Gu Chen ignored him and continued to do all kinds of deduction in the transcript.
Although Liao Feng's words can be used as a reference, Gu Chen can't believe all of them. After all, Zhang Hao, who was most likely to be the murderer, was immediately proved to be absent from the scene.
However, in order to verify whether it is true or not, Gu Chen has to go to the scene to investigate whether Liao Feng's words are true or not, and whether he is really not favoring Zhang Hao.
But think back, if Liao Feng really wants to be partial to Zhang Hao, why does he have to tell himself about Zhang Hao, Gao Cheng and Han Jing?
He can pretend to be deaf and dumb.
Therefore, Gu Chen is not good at judging the time, and can only perfunctorily say: "at present, it is not clear. Since you said that you eat out all night, can you tell me where you eat and when."
"Of course." Liao Feng readily agreed.
After waiting for Professor Zhang to come back, Professor Zhang and Liao Feng were immediately accompanied in the whole ward.
So Gu Chen, Lu Weiwei and officer Wang simply explained to several people that they saved the photos of Liao Feng and Zhang Hao, and then left the scene.
Drive all the way.
When we found the restaurant according to the address provided by Liao Feng, the three immediately got off the bus and investigated the surrounding environment.
Fortunately, roadside monitoring can cover the entrance area of the store, and it's already past midnight and the store is already closed.
Therefore, officer Wang can only call the control room on duty, and then after explaining the situation, he sent photos of Liao Feng and Zhang Hao in the past.
When Zhang Hao and the dispatcher are on duty, ask the police officer to help him.
About ten minutes later, officer Wang's phone rang suddenly.
"Hello? I'm Lao Wang. "
"You found it, didn't you? Well, send it quickly. "
"Yes, yes, there is still some time for entering the store, and there is also the front and rear doors of the store. Please check carefully to see if there is any exit from the back door. Yes, I'll take it right away. OK."
After a brief communication, officer Wang received a lot of information in his mobile wechat.
Gu Chen and Lu Weiwei immediately went up to check.
The colleagues in the control room are very efficient, and they can edit some words for prompt at the top of each screen.
The first text on the top of the screen is about the time of entering the store.
At that time, we found that Zhang Hao was driving a white car and parked in the parking space at the gate of the store. Five people immediately got off the car, including Liao Feng.
After a few people stop at the door for a short time, they walk in with shoulder to shoulder.
"Look at the second video." Lu Weiwei can't wait. She urges officer Wang.
"Don't worry." After officer Wang returns, he continues to click on the next screen.
The second paragraph of editing text at the top of the screen indicates the time when several people leave the restaurant.
It can be seen from the picture that Liao Feng, together with Zhang Hao and three other colleagues, came out of the restaurant feeling their belly.
Several people are still in the dining room door chatting a few words, this just disperses separately.
Liao Feng left first. He stopped a taxi on the side of the road and left.
After that, three people from the same industry also took different vehicles to leave. Finally, it was Zhang Hao. He also had some quarrels with the drivers of neighboring vehicles on the parking problem.
At this time, a voice message was sent from the control room.
Officer Wang directly clicks on the play.
[Lao Wang, we have checked these five people for you. They have never left the restaurant since they entered the restaurant until they came out of the restaurant. Whew >.
Lu Weiwei frowned and said, "it seems that Liao Feng didn't lie. They did eat in the restaurant tonight, and they didn't come out."
"Is it the wrong direction of our investigation?" Gu Chen shook his head and said with a self mocking smile: "there was a suspect who could be suspected just now. Now, as soon as we investigate, the suspect is washed white directly."
"What can I do?" Police officer Wang showed his hands and was helpless.
Now all the clues seem to have been broken
Gao Cheng, who is still in the intensive care unit, seems to be very popular and has not offended anyone.
And in the whole Nanshan laboratory, it is only because of Han Jing's affairs that Zhang Hao has something to do with him.
But now it seems that there is no relationship between Zhang Hao and tonight.
Gu Chen walked back and forth in front of the police car. Without thinking, he said, "elder martial brother Wang and sister Lu, I want to go to the laboratory again."
"Do you want to go?" Lu Weiwei doubts way.
Gu Chen nodded: "must go, perhaps is we have previously missed clues.""All right." Officer Wang has no clue now. He is ready to return to the scene with Gu Chen. Maybe he can find some new discoveries.
Driving a police car, the three returned to Nanshan laboratory.
At this moment, it was three o'clock in the morning.
When Gu Chen came to knock at the iron gate, an old man in the duty room slowly put on his coat and took a flashlight to shine at the window.
When he found that it was three policemen, he immediately opened the door of the duty room and came to open the door for several people.
"Comrades of the police, are you here again?"
"Sir, I disturb your sleep." Gu Chen said.
After the gate keeper opened the door, he waved his hand and said, "what can I do for you
"We're going to the lab to investigate, just the lab tonight." She said.
Uncle nodded: "I know, you go in. When you come out later, just tap on the window of my duty room. I will open the door for you."
"Thank you." She said.
The three continued to move on, but when Gu Chen was halfway there, he suddenly turned back to the duty room and asked the boss, "Sir, you are on duty tonight. Did you hear the explosion of the laboratory?"
"No The guard shook his head and said, "it's cold outside. I've been looking at my cell phone in the duty room. In addition to the noise at the door, I don't know what's going on inside the laboratory."
"Besides, these young people often make big noise in the laboratory. As long as no one is killed, I basically don't care."
"OK, thank you." Originally, he wanted to ask for some information at the head of the guard. It seems that it is still in vain now, and Gu Chen has to give up.
Came to the scene, Lu Weiwei directly took out the key given by Professor Zhang and opened the door of the laboratory.
Then the cordon is dead and the laboratory lights are turned on.
Suddenly, familiar scenes reappear.
Lu Weiwei and police officer Wang, some boring put on gloves and foot covers, continue to carry out internal inspection in the laboratory.
Gu Chen stood at the door, closed his eyes and thought.
Soon, Gu Chen's mind whirled.
Open your eyes again, everything in the laboratory is the same as before, all kinds of utensils are put in order.
Gao Chengzheng sat quietly at his desk and began to sort out the experimental materials.
Gu Chen sits down and looks at Gao Chen's side.
"Now in the laboratory, only Gao Cheng is on duty, and he has not carried out the experiment. However, what is the matter with that explosion?"
Thinking of this, Gu Chen suddenly hit a ring finger. In an instant, a violent explosion broke out in the quiet laboratory.
Gu Chen's eyes are black, only hear the sound of all kinds of glass debris falling, smashing the ground crackling.
Gu Chen hits his finger again
By this time, Gaocheng had fallen to the ground, and various pieces of glass had pierced all parts of his body.
Gao Cheng lies on the ground, struggling in pain.
He wanted to call for help, but at this time he was badly hurt and his voice seemed to be difficult to convey to the outside.
At this moment, all parts of the body are pricked, and the red blood flows out instantly.
Gao Cheng's body was slowly dyed a deep red.
He struggled a few times, breathing more and more weakly, until he slowly closed his eyes.
Gu Chen hits a ring finger, the whole space picture suddenly freeze frame.
"It's still glass, but there's no inflammable and explosive materials? Is it an explosion caused by pressure? "
Thinking of this, Gu Chen suddenly remembers that when he inspected the laboratory before, he once found the big stone and the piano wire with knots tied on the glass bottle cap, which made the whole person's thoughts surge.
"Are all these accidents?" Gu Chen frowned: "no, it's not by accident. These things that seem to have nothing to do with the laboratory will never appear here for no reason. Someone must have brought them in."
"But who is it? What is his intention? Why did he do it? "
Gu Chen continues to use his master level reasonable reasoning to gather these fragmentary clues together for free combination.
In my heart, I think of something.
"Yes, I've picked up a piece of debris before, and it smells like alcohol. That's strange."
Gu Chen suddenly, under the influence of his master level reasonable reasoning, added the alcohol element to the conditions and continued to combine.
"There was no dangerous nitroglycerin, no gunpowder and no trace of burning. How did the explosion happen? Is it related to alcohol? "
"But how does alcohol explode suddenly? Is there any other way out of consideration? "
Suddenly, he thought of the big stone and Piano silk, and Gu Chen suddenly laughed: "yes, these things seem to be used to fix glass bottles, as if to prevent something from overflowing."Also at the moment of reasoning, Gu Chen used his specialized memory to recall that he had found that the bookshelf was wet and still dripping in his laboratory investigation.
"Is the glass bottle with water on the shelf?" Gu Chen immediately hit a ring finger.
At this moment, a large glass bottle appears on the bookshelf, and Gu Chen looks back. At this time, it is only one meter away from Gaocheng.
"I know, I know." Gu Chen was suddenly overjoyed and said with a smile: "this is the way Gaocheng is injured. The glass bottle suddenly explodes with great power. All kinds of debris seriously hurt the unprepared Gaocheng."
Gu Chen also uses his specialized memory to think of the wound on Gaocheng lying in the hospital bed. It is indeed on the left side, which matches the position of Gaocheng's desk and bookshelf.
"That is to say, the glass bottle, indeed, exploded from the shelf, but what would it be?"
"Alcohol, water, big stone, piano wire."
After listing the clues found in his investigation, Gu Chen suddenly combined the four elements again.
"First of all, it's a glass bottle. Alcohol is volatile, so it must be put in the glass bottle. The piano wire tied to the glass bottle cap must be used to fix the bottle cap and prevent the contents from coming out because of pressure."
"And the stone. Yes, the lid is smooth, and it's hard to hold down the contents of the bottle. So if you press a stone on it and tie it firmly to the cap with strings, will that solve the problem?"
Gu Chen's ideas were further opened. It seems that all the conditions given just now can be combined at this moment.
"What does he want to do? What is the killer trying to do? Why are alcohol and water in glass bottles
"What's more, since the mouth of the bottle is firmly blocked, if the glass bottle wants to blow up Gaocheng seriously, it must be under extremely strong pressure in the glass bottle, but..."
Gu Chen is full of water and alcohol in his head now, but he can't think of it all the time. How can the two mix together to create such a great pressure?
Or is there another form between the two?
"The bookshelf is wet and still dripping. It seems that the glass bottle must be full of water, but water will not explode
"If it wasn't water, what would it be? Is it ice? "
Thinking of this, Gu Chen suddenly raised his head: "yes, it's dry ice, yes, it's dry ice."
"Dry ice and alcohol mixed together, the temperature can drop to - 80 degrees Celsius, how can I forget this matter?"
Gu Chen is also making use of his specialized memory, trying to recall the materials he looked up in the library before.
At that time did see the relevant knowledge, but because the time is far away, so the memory is slightly blurred.
But when Gu Chen thought of dry ice and alcohol, the vague knowledge seemed to light up in an instant.
"When dry ice is mixed with alcohol, the temperature can drop to about - 80 degrees Celsius, or even lower."
"The composition of dry ice is solid carbon dioxide, which will sublimate into gaseous carbon dioxide at room temperature. The chemical reaction is a change in the formation of new substances."
"But when dry ice and alcohol are put together, dry ice will sublimate and cool down, because the freezing point of alcohol is - 117 ℃
"Although dry ice sublimates and absorbs heat, the temperature will not drop to - 117 degrees Celsius, so alcohol will not solidify."
"But alcohol is made up of alcohol molecules, and dry ice is made up of carbon dioxide molecules. Both of these particles are quite stable and will not recombine to form new molecules, so dry ice will sublimate, and alcohol will still be liquid."
"Dry ice and alcohol will only lower the temperature to - 117 degrees. Isn't that the principle?"
"What's more, the water in the glass bottle freezes into ice and expands, causing an explosion."
Thinking of this, Gu Chen probably already knew how Gaocheng was injured by the explosion, so he immediately hit a ring finger.
In front of her eyes, when Gu Chen opens her eyes again, Lu Weiwei and officer Wang are still searching the room carefully.
But the two seem to be the same as before, is still nothing.
Gu Chen smiles and shakes his head, and enters the laboratory as if nothing happened.
"Brother Gu." Lu Weiwei, who was squatting on the ground to pick up the glass, immediately turned her head and looked at him: "I think, there seems to be some alcohol left on these pieces."
After sniffing at the tip of her nose, Lu Weiwei affirmed, "it's alcohol. The glass bottle must have been filled with alcohol before."
Gu Chen pretends not to know anything, and calmly walks to Lu Weiwei, and then learns from her just now, and puts the glass fragment on the tip of her nose and sniffs.
"How about it? Do you smell anything? " Wei Wei looks straight into the eyes.
Gu Chen was stunned and said in surprise: "elder martial sister Lu, you have observed very carefully. Yes, it has the smell of alcohol. But how can the wine explosion well when it is packed in a glass bottle? Is there pressure in the bottle? ""What kind of pressure is that great?" Asked officer Wang, who was also collecting clues.
Gu Chen shook his head as if nothing happened, and then asked Lu Weiwei, "sister Lu, have we found a piano wire tied to the broken glass bottle cap?"
"Yes." Lu Weiwei nods hard, and continues to add: "not only found the piano wire, but also the big stone."
"Piano wire? Big stone? The piano wire is still tied to the bottle cap. What is the big stone for? Is there a big stone tied to the piano wire Gu Chen deliberately in front of Lu Weiwei crazy hint.
Lu Weiwei also finally lived up to expectations. Under Gu Chen's various hints, she seemed to have found some new clues, so she hit a ring finger and said, "I know."
"What do you know?" Officer Wang looked at her curiously.
Lu Weiwei immediately stood up and said in a loud voice, "I just mentioned the pressure problem of the glass bottle, and the piano wire tied to the glass bottle cap. I think it is used to bind stones, and the function must be to prevent the things in the glass bottle from overflowing."
"Great, sister Lu!" Gu Chen pretended to be surprised and looked at her, then thought thoughtfully: "in this way, the contents in the bottle will explode because of the pressure, but what is it?"
Gu Chen looks at the bookshelf again.
Lu Weiwei also according to Gu Chen's eye prompt, not aware of Li casually said: "is it? Is it water? "
"Maybe Can it be a solid object of water? " Gu Chen continues to suggest crazily.
Lu Weiwei's brain is a bit disordered, but she still tries to think, and replies weakly: "can't it be ice?"
Gu Chen frowned and continued to doubt: "but ice and alcohol don't seem to be so powerful? Is it... "
"Dry Dry ice? "
Lu Weiwei casually said that Gu Chen seemed to get a major prompt immediately. He suddenly realized: "yes, it's dry ice. If dry ice and alcohol are mixed together, the temperature can drop to - 80 degrees Celsius?"
"If the water in the glass bottle freezes into ice, the volume will certainly expand. At that time, if the bottle cap is fixed and sealed with piano wire and stone, will it not explode?"
Lu Weichen's words seem to have no reaction from Lu Weichen
"There is Do you have any? " Lu Weiwei also stayed for a while, but she immediately began to laugh: "ha ha, I wanted to get along with everyone in a harmonious way with the identity of rowing, but what she got was doubts and rumors."
"Well, I don't pretend. I have a showdown. Yes, sometimes I'm shocked by my talent. I'm so honest."

Gu Chen ignored him and continued to do all kinds of deduction in the transcript.
Although Liao Feng's words can be used as a reference, Gu Chen can't believe all of them. After all, Zhang Hao, who was most likely to be the murderer, was immediately proved to be absent from the scene.

Lu Weiwei casually said that Gu Chen seemed to get a major prompt immediately. He suddenly realized: "yes, it's dry ice. If dry ice and alcohol are mixed together, the temperature can drop to - 80 degrees Celsius?"
"If the water in the glass bottle freezes into ice, the volume will certainly expand. At that time, if the bottle cap is fixed and sealed with piano wire and stone, will it not explode?"
Lu Weichen's words seem to have no reaction from Lu Weichen
"There is Do you have any? " Lu Weiwei also stayed for a while, but she immediately began to laugh: "ha ha, I wanted to get along with everyone in a harmonious way with the identity of rowing, but what she got was doubts and rumors."
"Well, I don't pretend. I have a showdown. Yes, sometimes I'm shocked by my talent. I'm so honest."

Gu Chen ignored him and continued to do all kinds of deduction in the transcript. Although Liao Feng's words can be used as a reference, Gu Chen can't believe all of them. After all, Zhang Hao, who was most likely to be the murderer, was immediately proved to be absent from the scene. However, in order to verify whether it is true or not, Gu Chen has to go to the scene to investigate whether Liao Feng's words are true or not, and whether he is really not favoring Zhang Hao. But think back, if Liao Feng really wants to be partial to Zhang Hao, why does he have to tell himself about Zhang Hao, Gao Cheng and Han Jing? He can pretend to be deaf and dumb. Therefore, Gu Chen is not good at judging the time, and can only perfunctorily say: "at present, it is not clear. Since you said that you eat out all night, can you tell me where you eat and when." "Of course." Liao Feng readily agreed. After waiting for Professor Zhang to come back, Professor Zhang and Liao Feng were immediately accompanied in the whole ward. So Gu Chen, Lu Weiwei and officer Wang simply explained to several people that they saved the photos of Liao Feng and Zhang Hao, and then left the scene. Drive all the way. When we found the restaurant according to the address provided by Liao Feng, the three immediately got off the bus and investigated the surrounding environment. Fortunately, roadside monitoring can cover the entrance area of the store, and it's already past midnight and the store is already closed. Therefore, officer Wang can only call the control room on duty, and then after explaining the situation, he sent photos of Liao Feng and Zhang Hao in the past. When Zhang Hao and the dispatcher are on duty, ask the police officer to help him. About ten minutes later, officer Wang's phone rang suddenly. "Hello? I'm Lao Wang. " "You found it, didn't you? Well, send it quickly. " "Yes, yes, there is still some time for entering the store, and there is also the front and rear doors of the store. Please check carefully to see if there is any exit from the back door. Yes, I'll take it right away. OK." After a brief communication, officer Wang received a lot of information in his mobile wechat. Gu Chen and Lu Weiwei immediately went up to check. The colleagues in the control room are very efficient, and they can edit some words for prompt at the top of each screen. The first text on the top of the screen is about the time of entering the store. At that time, we found that Zhang Hao was driving a white car and parked in the parking space at the gate of the store. Five people immediately got off the car, including Liao Feng. After a few people stop at the door for a short time, they walk in with shoulder to shoulder. "Look at the second video." Lu Weiwei can't wait. She urges officer Wang. "Don't worry." After officer Wang returns, he continues to click on the next screen. The second paragraph of editing text at the top of the screen indicates the time when several people leave the restaurant. It can be seen from the picture that Liao Feng, together with Zhang Hao and three other colleagues, came out of the restaurant feeling their belly. Several people are still in the dining room door chatting a few words, this just disperses separately. Liao Feng left first. He stopped a taxi on the side of the road and left. After that, three people from the same industry also took different vehicles to leave. Finally, it was Zhang Hao. He also had some quarrels with the drivers of neighboring vehicles on the parking problem. At this time, a voice message was sent from the control room. Officer Wang directly clicks on the play. Lao Wang, we have checked these five people for you. They have never left the restaurant since they entered the restaurant until they came out of the restaurant. Whew . Lu Weiwei frowned and said, "it seems that Liao Feng didn't lie. They did eat in the restaurant tonight, and they didn't come out." "Is it the wrong direction of our investigation?" Gu Chen shook his head and said with a self mocking smile: "there was a suspect who could be suspected just now. Now, as soon as we investigate, the suspect is washed white directly." "What can I do?" Police officer Wang showed his hands and was helpless. Now all the clues seem to have been broken Gao Cheng, who is still in the intensive care unit, seems to be very popular and has not offended anyone. And in the whole Nanshan laboratory, it is only because of Han Jing's affairs that Zhang Hao has something to do with him. But now it seems that there is no relationship between Zhang Hao and tonight. Gu Chen walked back and forth in front of the police car. Without thinking, he said, "elder martial brother Wang and sister Lu, I want to go to the laboratory again." "Do you want to go?" Lu Weiwei doubts way. Gu Chen nodded: "must go, perhaps is we have previously missed clues.""All right." Officer Wang has no clue now. He is ready to return to the scene with Gu Chen. Maybe he can find some new discoveries. Driving a police car, the three returned to Nanshan laboratory. At this moment, it was three o'clock in the morning. When Gu Chen came to knock at the iron gate, an old man in the duty room slowly put on his coat and took a flashlight to shine at the window. When he found that it was three policemen, he immediately opened the door of the duty room and came to open the door for several people. "Comrades of the police, are you here again?" "Sir, I disturb your sleep." Gu Chen said. After the gate keeper opened the door, he waved his hand and said, "what can I do for you "We're going to the lab to investigate, just the lab tonight." She said. Uncle nodded: "I know, you go in. When you come out later, just tap on the window of my duty room. I will open the door for you." "Thank you." She said. The three continued to move on, but when Gu Chen was halfway there, he suddenly turned back to the duty room and asked the boss, "Sir, you are on duty tonight. Did you hear the explosion of the laboratory?" "No The guard shook his head and said, "it's cold outside. I've been looking at my cell phone in the duty room. In addition to the noise at the door, I don't know what's going on inside the laboratory." "Besides, these young people often make big noise in the laboratory. As long as no one is killed, I basically don't care." "OK, thank you." Originally, he wanted to ask for some information at the head of the guard. It seems that it is still in vain now, and Gu Chen has to give up. Came to the scene, Lu Weiwei directly took out the key given by Professor Zhang and opened the door of the laboratory. Then the cordon is dead and the laboratory lights are turned on. Suddenly, familiar scenes reappear. Lu Weiwei and police officer Wang, some boring put on gloves and foot covers, continue to carry out internal inspection in the laboratory. Gu Chen stood at the door, closed his eyes and thought. Soon, Gu Chen's mind whirled. Open your eyes again, everything in the laboratory is the same as before, all kinds of utensils are put in order. Gao Chengzheng sat quietly at his desk and began to sort out the experimental materials. Gu Chen sits down and looks at Gao Chen's side. "Now in the laboratory, only Gao Cheng is on duty, and he has not carried out the experiment. However, what is the matter with that explosion?" Thinking of this, Gu Chen suddenly hit a ring finger. In an instant, a violent explosion broke out in the quiet laboratory. Gu Chen's eyes are black, only hear the sound of all kinds of glass debris falling, smashing the ground crackling. Gu Chen hits his finger again By this time, Gaocheng had fallen to the ground, and various pieces of glass had pierced all parts of his body. Gao Cheng lies on the ground, struggling in pain. He wanted to call for help, but at this time he was badly hurt and his voice seemed to be difficult to convey to the outside. At this moment, all parts of the body are pricked, and the red blood flows out instantly. Gao Cheng's body was slowly dyed a deep red. He struggled a few times, breathing more and more weakly, until he slowly closed his eyes. Gu Chen hits a ring finger, the whole space picture suddenly freeze frame. "It's still glass, but there's no inflammable and explosive materials? Is it an explosion caused by pressure? " Thinking of this, Gu Chen suddenly remembers that when he inspected the laboratory before, he once found the big stone and the piano wire with knots tied on the glass bottle cap, which made the whole person's thoughts surge. "Are all these accidents?" Gu Chen frowned: "no, it's not by accident. These things that seem to have nothing to do with the laboratory will never appear here for no reason. Someone must have brought them in." "But who is it? What is his intention? Why did he do it? " Gu Chen continues to use his master level reasonable reasoning to gather these fragmentary clues together for free combination. In my heart, I think of something. "Yes, I've picked up a piece of debris before, and it smells like alcohol. That's strange." Gu Chen suddenly, under the influence of his master level reasonable reasoning, added the alcohol element to the conditions and continued to combine. "There was no dangerous nitroglycerin, no gunpowder and no trace of burning. How did the explosion happen? Is it related to alcohol? " "But how does alcohol explode suddenly? Is there any other way out of consideration? " Suddenly, he thought of the big stone and Piano silk, and Gu Chen suddenly laughed: "yes, these things seem to be used to fix glass bottles, as if to prevent something from overflowing."Also at the moment of reasoning, Gu Chen used his specialized memory to recall that he had found that the bookshelf was wet and still dripping in his laboratory investigation. "Is the glass bottle with water on the shelf?" Gu Chen immediately hit a ring finger. At this moment, a large glass bottle appears on the bookshelf, and Gu Chen looks back. At this time, it is only one meter away from Gaocheng. "I know, I know." Gu Chen was suddenly overjoyed and said with a smile: "this is the way Gaocheng is injured. The glass bottle suddenly explodes with great power. All kinds of debris seriously hurt the unprepared Gaocheng." Gu Chen also uses his specialized memory to think of the wound on Gaocheng lying in the hospital bed. It is indeed on the left side, which matches the position of Gaocheng's desk and bookshelf. "That is to say, the glass bottle, indeed, exploded from the shelf, but what would it be?" "Alcohol, water, big stone, piano wire." After listing the clues found in his investigation, Gu Chen suddenly combined the four elements again. "First of all, it's a glass bottle. Alcohol is volatile, so it must be put in the glass bottle. The piano wire tied to the glass bottle cap must be used to fix the bottle cap and prevent the contents from coming out because of pressure." "And the stone. Yes, the lid is smooth, and it's hard to hold down the contents of the bottle. So if you press a stone on it and tie it firmly to the cap with strings, will that solve the problem?" Gu Chen's ideas were further opened. It seems that all the conditions given just now can be combined at this moment. "What does he want to do? What is the killer trying to do? Why are alcohol and water in glass bottles "What's more, since the mouth of the bottle is firmly blocked, if the glass bottle wants to blow up Gaocheng seriously, it must be under extremely strong pressure in the glass bottle, but..." Gu Chen is full of water and alcohol in his head now, but he can't think of it all the time. How can the two mix together to create such a great pressure? Or is there another form between the two? "The bookshelf is wet and still dripping. It seems that the glass bottle must be full of water, but water will not explode "If it wasn't water, what would it be? Is it ice? " Thinking of this, Gu Chen suddenly raised his head: "yes, it's dry ice, yes, it's dry ice." "Dry ice and alcohol mixed together, the temperature can drop to - 80 degrees Celsius, how can I forget this matter?" Gu Chen is also making use of his specialized memory, trying to recall the materials he looked up in the library before. At that time did see the relevant knowledge, but because the time is far away, so the memory is slightly blurred. But when Gu Chen thought of dry ice and alcohol, the vague knowledge seemed to light up in an instant. "When dry ice is mixed with alcohol, the temperature can drop to about - 80 degrees Celsius, or even lower." "The composition of dry ice is solid carbon dioxide, which will sublimate into gaseous carbon dioxide at room temperature. The chemical reaction is a change in the formation of new substances." "But when dry ice and alcohol are put together, dry ice will sublimate and cool down, because the freezing point of alcohol is - 117 "Although dry ice sublimates and absorbs heat, the temperature will not drop to - 117 degrees Celsius, so alcohol will not solidify." "But alcohol is made up of alcohol molecules, and dry ice is made up of carbon dioxide molecules. Both of these particles are quite stable and will not recombine to form new molecules, so dry ice will sublimate, and alcohol will still be liquid." "Dry ice and alcohol will only lower the temperature to - 117 degrees. Isn't that the principle?" "What's more, the water in the glass bottle freezes into ice and expands, causing an explosion." Thinking of this, Gu Chen probably already knew how Gaocheng was injured by the explosion, so he immediately hit a ring finger. In front of her eyes, when Gu Chen opens her eyes again, Lu Weiwei and officer Wang are still searching the room carefully. But the two seem to be the same as before, is still nothing. Gu Chen smiles and shakes his head, and enters the laboratory as if nothing happened. "Brother Gu." Lu Weiwei, who was squatting on the ground to pick up the glass, immediately turned her head and looked at him: "I think, there seems to be some alcohol left on these pieces." After sniffing at the tip of her nose, Lu Weiwei affirmed, "it's alcohol. The glass bottle must have been filled with alcohol before." Gu Chen pretends not to know anything, and calmly walks to Lu Weiwei, and then learns from her just now, and puts the glass fragment on the tip of her nose and sniffs. "How about it? Do you smell anything? " Wei Wei looks straight into the eyes. Gu Chen was stunned and said in surprise: "elder martial sister Lu, you have observed very carefully. Yes, it has the smell of alcohol. But how can the wine explosion well when it is packed in a glass bottle? Is there pressure in the bottle? ""What kind of pressure is that great?" Asked officer Wang, who was also collecting clues. Gu Chen shook his head as if nothing happened, and then asked Lu Weiwei, "sister Lu, have we found a piano wire tied to the broken glass bottle cap?" "Yes." Lu Weiwei nods hard, and continues to add: "not only found the piano wire, but also the big stone." "Piano wire? Big stone? The piano wire is still tied to the bottle cap. What is the big stone for? Is there a big stone tied to the piano wire Gu Chen deliberately in front of Lu Weiwei crazy hint. Lu Weiwei also finally lived up to expectations. Under Gu Chen's various hints, she seemed to have found some new clues, so she hit a ring finger and said, "I know." "What do you know?" Officer Wang looked at her curiously. Lu Weiwei immediately stood up and said in a loud voice, "I just mentioned the pressure problem of the glass bottle, and the piano wire tied to the glass bottle cap. I think it is used to bind stones, and the function must be to prevent the things in the glass bottle from overflowing." "Great, sister Lu!" Gu Chen pretended to be surprised and looked at her, then thought thoughtfully: "in this way, the contents in the bottle will explode because of the pressure, but what is it?" Gu Chen looks at the bookshelf again. Lu Weiwei also according to Gu Chen's eye prompt, not aware of Li casually said: "is it? Is it water? " "Maybe Can it be a solid object of water? " Gu Chen continues to suggest crazily. Lu Weiwei's brain is a bit disordered, but she still tries to think, and replies weakly: "can't it be ice?" Gu Chen frowned and continued to doubt: "but ice and alcohol don't seem to be so powerful? Is it... " "Dry Dry ice? " Lu Weiwei casually said that Gu Chen seemed to get a major prompt immediately. He suddenly realized: "yes, it's dry ice. If dry ice and alcohol are mixed together, the temperature can drop to - 80 degrees Celsius?" "If the water in the glass bottle freezes into ice, the volume will certainly expand. At that time, if the bottle cap is fixed and sealed with piano wire and stone, will it not explode?" Lu Weichen's words seem to have no reaction from Lu Weichen "There is Do you have any? " Lu Weiwei also stayed for a while, but she immediately began to laugh: "ha ha, I wanted to get along with everyone in a harmonious way with the identity of rowing, but what she got was doubts and rumors." "Well, I don't pretend. I have a showdown. Yes, sometimes I'm shocked by my talent. I'm so honest." Officer Wang: www.mylovenovel.com , the fastest update of the webnovel!
