Control room.
While everyone was arguing about the masquerade arsonist, Gu Chen stood quietly by himself.
In my opinion, the purpose of this man's arson is secondary, and the key is to find the trace of this man's evacuation.
From the side of the road monitoring, we can see that the arson took off a wig and coat, so we can judge that this is a man dressed as a female suspect.
But after all, the monitoring outside Jinma Furniture Plaza, because of renovation factors, led to the removal of all monitoring systems.
But in this way, everyone lost a clue at the exit of the alley.
And what roadside monitoring can capture is only a long-range picture, and the position where the man appears is only a corner of the lens.
As a result, the pursuit of suspect seems to be a big problem.
"But did he really leave like this?" Gu Chen took a deep breath and asked himself.
"Judging from the clues available at present, the arsonist obviously knows very well about the renovation plan of Jinma furniture Square and is fully prepared."
"And the man came with tool pliers. Obviously, he came prepared. After entering Jinma furniture Square, he cut off the door locks of some shops."
"After entering the house, directly ignite inflammables. The action is skilled, professional and purposeful."
"And from the monitoring screen, it seems to be a random crime, not for a specific shop."
Gu Chen looked up at the main screen in front of him and thought deeply: "if so, his goal is only Jinma furniture Square, whether it is a specific shop or not."
"No matter what his purpose is, will the criminal suspect not come back to see his masterpiece after he leaves?"
Gu Chen has reason to believe that most of the suspects will return to the scene at the same time when the crowd is gathered, so as to confirm the effect of their crime.
This may seem incredible to many people.
But from a psychological point of view, most suspect can not evade this problem.
Of course, the suspect's return to the scene also needs to meet some objective conditions.
For example, a large number of people gather.
Only in this way, the appearance of the suspect can not be easily discovered by the police.
However, it can be seen from the monitoring picture that after the fire broke out in Jinma furniture Square, the fire brigade was also on duty and evacuated a large number of residents.
A large number of residents ran out of their homes overnight to avoid the fire, which also made the roads around the whole Jinma furniture Square crowded.
Not only fire engines, police cars, but also ambulances are on standby.
This situation obviously provides the possibility for the suspect to return to the scene.
"Elder martial brother Gu." seeing that Gu Chen has been lost in thought, Lu Weiwei couldn't help asking him, "what are you thinking?"
"I wonder if this guy will return to the scene when evacuating the crowd after escaping?"
Gu Chen also said what he thought.
Lu Weiwei smells, and nods, "well, there's such a possibility. Generally, the suspect will have the psychology of returning to the scene, especially with so many evacuating residents."
"But......" hesitated for a few seconds, Lu Weiwei added, "but there are so many crowds that even if a criminal suspect appears, maybe he will appear in another disguised form. How can we find him from so many scattered masses at that time?"
"That's right." Gu Chen nodded slightly and agreed. "At present, it's not easy to find this guy among hundreds of people, but it's not impossible."
"Gu Chen." officer Wang heard two people talking, and walked to Gu Chen's side. He asked, "if the suspect appears in the picture, are you sure you can find him?"
"No." Gu Chen shook his head first and then said, "but I can try."
"Gu team." the tall and thin trainee policeman was a little surprised, but also reminded and said, "that's hundreds of people?"
"How about hundreds of people?" Gu Chen saw that the young trainee policeman didn't seem to understand the investigation method at all. He also reminded him: "you should first distinguish between evacuees and bystanders."
"Most of the people evacuated came out of the residential building above the Jinma furniture Square. There are only a few exits. You can observe them carefully and record them."
Seeing the tall and thin trainee police with a confused face, it seems that this is a huge project.
So Gu Chen said again, "although there may be hundreds of these people, they can all choose to exclude."
"Once these huge cardinal numbers are excluded, the remaining bystanders may be much easier to distinguish."
"After all, normal people are sleeping at night. Even if a fire is found in Jinma furniture Square, most people will only wait and see at home."
"Only a small number of people will choose to go out of the house and join the fun outside, but this base will not be many."
Looking at the tall and thin trainee police, Gu Chen also smiled and said: "so this exclusion method can quickly eliminate most of the base population."
"The rest, excluding firefighters and police, are those onlookers."
"The number of these people can never be very large."
"But..." the strong trainee policeman on the other side hesitated for two seconds, and then asked again: "but these people are clustered together, it's hard to distinguish."
"It's too difficult for you to distinguish such a huge base on this main screen?"
"Yes." the three-level superintendent heard the speech and quickly echoed, "it may be easy for you to say that dozens of people stand in the same monitoring picture and check."
"But it involves hundreds of people, which is a little troublesome."
"Only you think it will be difficult, but it is not difficult for us to check."
It seems that it is very difficult to monitor and investigate these police in the control room.
No wonder these people misunderstood the little boy and mistook the little boy for the suspect of rowing, so there was a big misunderstanding.
If Gu Chen hadn't corrected it in time, the shadow area of the little boy's childhood might not be known.
In particular, the view of the police may also lay a curse, and may dislike the police.
Therefore, Gu Chen also strives to be accurate and efficient in many cases, and never perfunctory.
But then again, in the face of a large number of evacuees, it is also very difficult for these police officers to identify arson suspects.
But Gu Chen has master observation and master memory.
Coupled with the continuous training of their own abilities, they have been able to integrate these abilities well.
In particular, it can make corresponding strategic adjustments according to the actual situation.
Therefore, in Gu Chen's view, it may not be difficult for the three police officers to complete the task that is impossible.
But the difficulty is whether the arsonist will appear.
Seeing the three people with a skeptical attitude, Gu Chen also opened the door to the mountain: "elder martial brother he, you turn back the monitoring time. I want the picture before these residents evacuate."
"I understand." he Junchao, who has been working with Gu Chen for many years, certainly knows what Gu Chen means.
Gu Chen wants to use his super memory to eliminate these evacuated residents.
It is also an operation video screen, which returns directly to before evacuation.
At this moment, in the main screen, Lao Ma is discussing countermeasures with the police on duty.
After simple communication, some firefighters rushed to the residential building directly with the police on duty and began to guide the evacuation.
Before long, in the picture, several residents in pajamas came out of the exit.
At first there were two or three people, then four or five groups, and then almost in line to the street.
Gu Chen was absorbed and stared at the screen.
Use your master memory to firmly remember everyone's specific characteristics.
Of course, it may be difficult to remember the appearance characteristics of hundreds of people only by master observation.
But Gu Chen skillfully used some special memory methods
For example, people evacuated from residential buildings are basically awakened from sleep.
Therefore, people will dress casually.
Some are in pajamas, some are even bare.
But everyone has a remarkable feature, that is, wearing slippers.
Gu Chen uses his master memory and observation to remember the specific characteristics of these people.
While observing the shoes on these people's feet to confirm whether they are all wearing slippers.
However, Gu Chen is gratified that almost all the evacuated residents are slippers of the same color.
"Stop." seeing the residential building upstairs in Jinma furniture Square, Gu Chen resolutely stopped the monitoring picture after no one came downstairs.
Then he said, "rewind the picture at the scene. I want to see it again."
"Is it going back to the time just now?" he Junchao asked.
"That's right." Gu Chen nodded slightly.
This time, Gu Chen's focus of observation should be shifted from these evacuated residents to focus on the later onlookers.
On the other hand, he Junchao obeyed and continued to operate the monitoring screen.
This time, Gu Chen once again asked to speed up the playback progress of monitoring.
With the increasing fire, smoke billowed around.
From different angles in the monitoring picture, many bystanders began to appear.
Although the number is also increasing, Gu Chen noticed the specific clothes of these people, especially shoes.
Like those evacuated residents, most of the people who came out to watch the fire were wearing slippers.
But in the crowd, Gu Chen suddenly found a suspicious looking person.
The point is that the man came out of the alley in board shoes.
"Stop!" Gu Chen stopped the monitoring again and hurriedly said, "turn back the time for 5 minutes, focusing on the alley next to Jinma furniture Square."
"I see." he Junchao obeyed and directly played back the picture for 5 minutes according to Gu Chen's meaning.
At this moment, the man in black whom Gu Chen focuses on appears in the picture again.
The man first looked around and confirmed that there were several evacuated people passing by. Then he pretended to be nothing and went into the crowd.
From the movement point of view, it seems very casual and can't see any difference.
But this pair of white board shoes is particularly eye-catching.
Due to Gu Chen's previous reminder, everyone turned their attention to the man in black.
Lu Weiwei also saw the clue and hurriedly said, "the man in black, the little white shoes he wears on his feet seem to be the same as those on the arsonist's feet."
"That's right." officer Wang also found something fishy and said quickly, "everyone is wearing slippers, but only he is wearing board shoes. This guy... Is a little unusual."
"Focus on him." seeing that his colleagues have understood their meaning, Gu Chen also hurriedly reminded him.
He Junchao nodded silently, in order to make people accurately find the shuttle man among a large number of people.
He Junchao directly operated the mouse to circle the man's trace on the main screen with a red line.
"Do you see?" seeing that the man's whereabouts had been exposed, Gu Chen went directly to the main screen, turned around and said to everyone:
"The place where the suspect disappeared is the alley of Jinma Furniture City, and the place where the man came out is precisely this alley, which seems very coincidental."
"And this man has been wandering around here. Looking around, he seems to be vigilant. Then he returns to this position, which is the place where he came out of Jinma furniture city."
"HMM." seeing Gu Chen's introduction, officer Wang also held his chest with both hands, nodded and said, "we can also boldly assume that this mall, this exit and these stores are likely to be his place of stay."
"From the previous video, we can see that after the suspect entered the shopping mall, he did not take away any property, so his motive was not a financial gain, but it could be a deeper reason."
"Yes," Lu Weiwei nodded. He hurriedly added, "moreover, the suspect knows the layout of the camera nearby the shopping mall."
"Later, we also found that after camouflage, the man took off his coat and wig. His body shape at that time was very similar to that of the man in black."
"Moreover, he is also wearing the same small white shoes, but others are wearing slippers, which is too different."
"This... Even if it's found?" listening to the discussion, the tall and thin trainee policeman whispered, feeling a little incredible.
Of course, these thoughts were broken and soon captured by Lu Weiwei.
Lu Weiwei glanced at the tall and thin trainee policeman, who also had no good airway: "so, what you think is very difficult, as long as you pay more attention, it is actually very easy to solve."
"Take the investigation just now. You also know how to investigate the evacuation of hundreds of people? Don't you use your brain to focus on their clothes, especially their shoes, instead of the number of people."
"I see. Elder martial sister Lu, I've been taught."
The tall and thin trainee policeman was embarrassed.
The heart said the criticism was worth it.
You know, when Gu Chen came here last time, he criticized several people because they worked hastily and confused black and white with an untrue car rowing incident.
This time, Gu Chen used his major to tell everyone that difficulties are not terrible, but that he is frightened by difficulties.
And Gu Chen's investigation method also quickly produced results. At least, we have found the suspect from a large number of people.
Gu Chen held his chest with both hands and stared at the screen again. He couldn't help saying, "this person may be a nearby resident or a surrounding owner, such as the operator of a store or something."
"To inquire about this person, we'd better find some relevant decoration personnel and take photos of arsonists taking off their wigs and coats to identify them."
"After all, I know that the monitoring system of Jinma furniture plaza is to be demolished. Obviously, the arsonists also know very well. When to demolish it, we have to ask these people who are engaged in decoration."
"And those engaged in decoration should have had more or less contact with arsonists. If they were given it to them for identification, perhaps the accuracy would be higher."
"I agree." as soon as Gu Chen's voice fell, Lu Weiwei raised her hand and said, "why can the arsonist enter the golden horse furniture Square, like a deserted place."
"Obviously, he knows very well about the renovation progress of Jinma furniture Square. Maybe he has made it clear that all monitoring systems of Jinma furniture Square will be dismantled yesterday morning."
After a pause, Lu Weiwei also took two laps in front of the crowd and said, "but what he never thought was that there was monitoring. It didn't use the same line, and it was a wide-angle lens."
"But from the previous situation, he may have communicated with the decoration personnel. Let's ask the decoration personnel. Maybe everything will come out."
"What are you waiting for?" officer Wang couldn't wait and hurriedly said, "what, he Junchao, hurry up and see where he finally went?"
"It's the fastest." he Junchao complained on his face and said, "finally, this man disappeared in the alley next to Jinma furniture Square."
"OK." officer Wang was satisfied with this and turned to Gu Chen and said, "let's go now?"
"Let's go now." Gu Chen also said in a positive tone.
There was a movement in the dispatching room. Gu Chen quickly took the members of the criminal investigation team out of the gate and went directly to the parking lot of the compound.
Driving to the crime scene again, it was already 11 a.m.
Although the fire in Jinma furniture plaza was put out in time and protected by smoke sprinkler, it was not seriously damaged although it was burned in a mess.
The nine fires were the hardest hit areas, and there was not much damage in other places.
However, the power supply was interrupted by the fire, which also caused many potential safety hazards.
Therefore, the police at the scene have evacuated those shops and businesses, and the police have set up a cordon around and refused anyone to approach again.
While Gu Chen arrived at the scene, his roommates Ding Liang and Huang Zunlong, with several auxiliary policemen, were explaining some information according to the pictures sent by Gu Chen and began to inquire about the surrounding residents and businesses.
It seems that he wants to find out the real murderer ahead of Gu Chen.

The action is skilled, professional and purposeful.""And from the monitoring screen, it seems to be a random crime, not for a specific shop."Gu Chen looked up at the main screen in front of him and thought deeply: "if so, his goal is only Jinma furniture Square, whether it is a specific shop or not.""No matter what his purpose is, will the criminal suspect not come back to see his masterpiece after he leaves?"Gu Chen has reason to believe that most of the suspects will return to the scene at the same time when the crowd is gathered, so as to confirm the effect of their crime.This may seem incredible to many people.But from a psychological point of view, most suspect can not evade this problem.Of course, the suspect's return to the scene also needs to meet some objective conditions.For example, a large number of people gather.Only in this way, the appearance of the suspect can not be easily discovered by the police.However, it can be seen from the monitoring picture that after the fire broke out in Jinma furniture Square, the fire brigade was also on duty and evacuated a large number of residents.A large number of residents ran out of their homes overnight to avoid the fire, which also made the roads around the whole Jinma furniture Square crowded.Not only fire engines, police cars, but also ambulances are on standby.This situation obviously provides the possibility for the suspect to return to the scene."Elder martial brother Gu." seeing that Gu Chen has been lost in thought, Lu Weiwei couldn't help asking him, "what are you thinking?""I wonder if this guy will return to the scene when evacuating the crowd after escaping?"Gu Chen also said what he thought.Lu Weiwei smells, and nods, "well, there's such a possibility. Generally, the suspect will have the psychology of returning to the scene, especially with so many evacuating residents.""But......" hesitated for a few seconds, Lu Weiwei added, "but there are so many crowds that even if a criminal suspect appears, maybe he will appear in another disguised form. How can we find him from so many scattered masses at that time?""That's right." Gu Chen nodded slightly and agreed. "At present, it's not easy to find this guy among hundreds of people, but it's not impossible.""Gu Chen." officer Wang heard two people talking, and walked to Gu Chen's side. He asked, "if the suspect appears in the picture, are you sure you can find him?""No." Gu Chen shook his head first and then said, "but I can try.""Gu team." the tall and thin trainee policeman was a little surprised, but also reminded and said, "that's hundreds of people?""How about hundreds of people?" Gu Chen saw that the young trainee policeman didn't seem to understand the investigation method at all. He also reminded him: "you should first distinguish between evacuees and bystanders.""Most of the people evacuated came out of the residential building above the Jinma furniture Square. There are only a few exits. You can observe them carefully and record them."Seeing the tall and thin trainee police with a confused face, it seems that this is a huge project.So Gu Chen said again, "although there may be hundreds of these people, they can all choose to exclude.""Once these huge cardinal numbers are excluded, the remaining bystanders may be much easier to distinguish.""After all, normal people are sleeping at night. Even if a fire is found in Jinma furniture Square, most people will only wait and see at home.""Only a small number of people will choose to go out of the house and join the fun outside, but this base will not be many."Looking at the tall and thin trainee police, Gu Chen also smiled and said: "so this exclusion method can quickly eliminate most of the base population.""The rest, excluding firefighters and police, are those onlookers.""The number of these people can never be very large.""But..." the strong trainee policeman on the other side hesitated for two seconds, and then asked again: "but these people are clustered together, it's hard to distinguish.""It's too difficult for you to distinguish such a huge base on this main screen?""Yes." the three-level superintendent heard the speech and quickly echoed, "it may be easy for you to say that dozens of people stand in the same monitoring picture and check.""But it involves hundreds of people, which is a little troublesome.""Only you think it will be difficult, but it is not difficult for us to check."It seems that it is very difficult to monitor and investigate these police in the control room.No wonder these people misunderstood the little boy and mistook the little boy for the suspect of rowing, so there was a big misunderstanding.If Gu Chen hadn't corrected it in time, the shadow area of the little boy's childhood might not be known.In particular, the view of the police may also lay a curse, and may dislike the police.Therefore, Gu Chen also strives to be accurate and efficient in many cases, and never perfunctory.But then again, in the face of a large number of evacuees, it is also very difficult for these police officers to identify arson suspects.But Gu Chen has master observation and master memory.Coupled with the continuous training of their own abilities, they have been able to integrate these abilities well.In particular, it can make corresponding strategic adjustments according to the actual situation.Therefore, in Gu Chen's view, it may not be difficult for the three police officers to complete the task that is impossible.But the difficulty is whether the arsonist will appear.Seeing the three people with a skeptical attitude, Gu Chen also opened the door to the mountain: "elder martial brother he, you turn back the monitoring time. I want the picture before these residents evacuate.""I understand." he Junchao, who has been working with Gu Chen for many years, certainly knows what Gu Chen means.Gu Chen wants to use his super memory to eliminate these evacuated residents.It is also an operation video screen, which returns directly to before evacuation.At this moment, in the main screen, Lao Ma is discussing countermeasures with the police on duty.After simple communication, some firefighters rushed to the residential building directly with the police on duty and began to guide the evacuation.Before long, in the picture, several residents in pajamas came out of the exit.At first there were two or three people, then four or five groups, and then almost in line to the street.Gu Chen was absorbed and stared at the screen.Use your master memory to firmly remember everyone's specific characteristics.Of course, it may be difficult to remember the appearance characteristics of hundreds of people only by master observation.But Gu Chen skillfully used some special memory methodsFor example, people evacuated from residential buildings are basically awakened from sleep.Therefore, people will dress casually.Some are in pajamas, some are even bare.But everyone has a remarkable feature, that is, wearing slippers.Gu Chen uses his master memory and observation to remember the specific characteristics of these people.While observing the shoes on these people's feet to confirm whether they are all wearing slippers.However, Gu Chen is gratified that almost all the evacuated residents are slippers of the same color."Stop." seeing the residential building upstairs in Jinma furniture Square, Gu Chen resolutely stopped the monitoring picture after no one came downstairs.Then he said, "rewind the picture at the scene. I want to see it again.""Is it going back to the time just now?" he Junchao asked."That's right." Gu Chen nodded slightly.This time, Gu Chen's focus of observation should be shifted from these evacuated residents to focus on the later onlookers.On the other hand, he Junchao obeyed and continued to operate the monitoring screen.This time, Gu Chen once again asked to speed up the playback progress of monitoring.With the increasing fire, smoke billowed around.From different angles in the monitoring picture, many bystanders began to appear.Although the number is also increasing, Gu Chen noticed the specific clothes of these people, especially shoes.Like those evacuated residents, most of the people who came out to watch the fire were wearing slippers.But in the crowd, Gu Chen suddenly found a suspicious looking person.The point is that the man came out of the alley in board shoes."Stop!" Gu Chen stopped the monitoring again and hurriedly said, "turn back the time for 5 minutes, focusing on the alley next to Jinma furniture Square.""I see." he Junchao obeyed and directly played back the picture for 5 minutes according to Gu Chen's meaning.At this moment, the man in black whom Gu Chen focuses on appears in the picture again.The man first looked around and confirmed that there were several evacuated people passing by. Then he pretended to be nothing and went into the crowd.From the movement point of view, it seems very casual and can't see any difference.But this pair of white board shoes is particularly eye-catching.Due to Gu Chen's previous reminder, everyone turned their attention to the man in black.Lu Weiwei also saw the clue and hurriedly said, "the man in black, the little white shoes he wears on his feet seem to be the same as those on the arsonist's feet.""That's right." officer Wang also found something fishy and said quickly, "everyone is wearing slippers, but only he is wearing board shoes. This guy... Is a little unusual.""Focus on him." seeing that his colleagues have understood their meaning, Gu Chen also hurriedly reminded him.He Junchao nodded silently, in order to make people accurately find the shuttle man among a large number of people.He Junchao directly operated the mouse to circle the man's trace on the main screen with a red line."Do you see?" seeing that the man's whereabouts had been exposed, Gu Chen went directly to the main screen, turned around and said to everyone:"The place where the suspect disappeared is the alley of Jinma Furniture City, and the place where the man came out is precisely this alley, which seems very coincidental.""And this man has been wandering around here. Looking around, he seems to be vigilant. Then he returns to this position, which is the place where he came out of Jinma furniture city.""HMM." seeing Gu Chen's introduction, officer Wang also held his chest with both hands, nodded and said, "we can also boldly assume that this mall, this exit and these stores are likely to be his place of stay.""From the previous video, we can see that after the suspect entered the shopping mall, he did not take away any property, so his motive was not a financial gain, but it could be a deeper reason.""Yes," Lu Weiwei nodded. He hurriedly added, "moreover, the suspect knows the layout of the camera nearby the shopping mall.""Later, we also found that after camouflage, the man took off his coat and wig. His body shape at that time was very similar to that of the man in black.""Moreover, he is also wearing the same small white shoes, but others are wearing slippers, which is too different.""This... Even if it's found?" listening to the discussion, the tall and thin trainee policeman whispered, feeling a little incredible.Of course, these thoughts were broken and soon captured by Lu Weiwei.Lu Weiwei glanced at the tall and thin trainee policeman, who also had no good airway: "so, what you think is very difficult, as long as you pay more attention, it is actually very easy to solve.""Take the investigation just now. You also know how to investigate the evacuation of hundreds of people? Don't you use your brain to focus on their clothes, especially their shoes, instead of the number of people.""I see. Elder martial sister Lu, I've been taught."The tall and thin trainee policeman was embarrassed.The heart said the criticism was worth it.You know, when Gu Chen came here last time, he criticized several people because they worked hastily and confused black and white with an untrue car rowing incident.This time, Gu Chen used his major to tell everyone that difficulties are not terrible, but that he is frightened by difficulties.And Gu Chen's investigation method also quickly produced results. At least, we have found the suspect from a large number of people.Gu Chen held his chest with both hands and stared at the screen again. He couldn't help saying, "this person may be a nearby resident or a surrounding owner, such as the operator of a store or something.""To inquire about this person, we'd better find some relevant decoration personnel and take photos of arsonists taking off their wigs and coats to identify them.""After all, I know that the monitoring system of Jinma furniture plaza is to be demolished. Obviously, the arsonists also know very well. When to demolish it, we have to ask these people who are engaged in decoration.""And those engaged in decoration should have had more or less contact with arsonists. If they were given it to them for identification, perhaps the accuracy would be higher.""I agree." as soon as Gu Chen's voice fell, Lu Weiwei raised her hand and said, "why can the arsonist enter the golden horse furniture Square, like a deserted place.""Obviously, he knows very well about the renovation progress of Jinma furniture Square. Maybe he has made it clear that all monitoring systems of Jinma furniture Square will be dismantled yesterday morning."After a pause, Lu Weiwei also took two laps in front of the crowd and said, "but what he never thought was that there was monitoring. It didn't use the same line, and it was a wide-angle lens.""But from the previous situation, he may have communicated with the decoration personnel. Let's ask the decoration personnel. Maybe everything will come out.""What are you waiting for?" officer Wang couldn't wait and hurriedly said, "what, he Junchao, hurry up and see where he finally went?""It's the fastest." he Junchao complained on his face and said, "finally, this man disappeared in the alley next to Jinma furniture Square.""OK." officer Wang was satisfied with this and turned to Gu Chen and said, "let's go now?""Let's go now." Gu Chen also said in a positive tone.There was a movement in the dispatching room. Gu Chen quickly took the members of the criminal investigation team out of the gate and went directly to the parking lot of the compound.Driving to the crime scene again, it was already 11 a.m.Although the fire in Jinma furniture plaza was put out in time and protected by smoke sprinkler, it was not seriously damaged although it was burned in a mess.The nine fires were the hardest hit areas, and there was not much damage in other places.However, the power supply was interrupted by the fire, which also caused many potential safety hazards.Therefore, the police at the scene have evacuated those shops and businesses, and the police have set up a cordon around and refused anyone to approach again.While Gu Chen arrived at the scene, his roommates Ding Liang and Huang Zunlong, with several auxiliary policemen, were explaining some information according to the pictures sent by Gu Chen and began to inquire about the surrounding residents and businesses.It seems that he wants to find out the real murderer ahead of Gu Chen.www.mylovenovel.com, the fastest update of the webnovel!
