Ren Yu and Qi Xiao went to have a meal and watch a movie first. At night, they each called a few friends to go to the bar they often go to.
In fact, Ren Yu likes drinking very much. Although he doesn't drink too much, they strictly prohibit drinking when they are on duty. It's rare to have a holiday. Naturally, they should relax.
In the middle of the night, a group of talents gradually dispersed. Ren Yu drank a lot, but he could walk steadily. Qi Xiao hung dangerously on him.
In front of the car, Ren Teng took out his hand and took out his mobile phone: "wait, I'll call a valet."
Qi Xiao put his arms around Ren Yu's neck. He raised his head, put his warm lips on it and kissed Ren Yu gently.
Ren Yi put his arms around his waist and said vaguely, "OK, let's go home first."
Qi Xiao stared at Ren Yu with blurred eyes and whispered, "brother, you are very good, especially good."
"Well, I know." Ren Yu smiled, "what's the matter with you? This is."
"Actually... I really want to be serious with you." Qi Xiao said drunkenly, "but I feel that now... I'm nothing, neither red nor rich, so I'm not qualified to fall in love."
Ren Yu comforted, "you're only 23. What's the hurry? You'll be red." He placed an order on the software and waited for the valet to come.
"Now those children, teenagers, cough, have entered the entertainment industry." Qi Xiao rubbed Ren Yu's face with his cheek. "The one who just accosted you, eighteen or nine years old, you... Will you also be robbed by the young."
"Pure nonsense." Ren Yu laughed, "I'll take you back to have a good sleep."
"You... Why don't you fall in love?"
"I don't have time."
Qi Xiao looked at Ren Yu with a silly smile: "why don't... Let's try?"
Ren Yi rubbed Qi Xiao's hair and said softly, "wait until you wake up." He doesn't want to fall in love, but he knows that there are too many differences between him and Qi Xiao from background to pursuit to values. I'm afraid he can't talk about feelings.
Qi Xiao hugged Ren Yu's waist, and the whole person hung on him. His face was buried in his chest and rubbed slowly, like a clever cat.
After a while, Dai Jia came. Ren Yu got Qi Xiao on the bus and found that he was already asleep.
He asked the valet to drive to Qi Xiao's house.
----
At dawn, Ren Yu was awakened by the phone. He vaguely grabbed the mobile phone on the bedside table, stuck it to his ear and "fed" it in a hoarse voice.
The other end of the phone paused: "Why are you still sleeping at this point?"
Gong Yingxian's cold voice poured on Ren Yu's face like a bottle of cold water. He suddenly woke him up. He reluctantly opened his eyes: "what time is it?" After asking, he looked at the mobile phone screen. It was almost nine o'clock.
"You drank." Gong Yingxian's voice was obviously a little unhappy.
"Ah, I drank very late with my friends last night." Ren Yu got up, "I really haven't woke up so late for a long time... What's the matter?"
"Forget it." Gong Yingxian simply hung up the phone.
Ren Ying listened to the busy tone on the other end of the phone and was stunned for a long time. When he finally recovered, he remembered that the two made an appointment to go to Wanyuan community again yesterday. The blockade of the fire scene cannot be too long because it will affect the normal life of the people, which is different from the bar, so their time is limited.
He was so drunk last night that he forgot.
Ren Yu beat his head, got up from the sofa and went to the bathroom to wash.
Last night, he spent the night here with Qi Xiao. After he put Qi Xiao to bed, he was too sleepy to move. He also fell asleep directly into bed. When he woke up, he had a sore back, dizziness and vomiting, typical hangover sequelae.
When he took a bath, Qi Xiao was still sleeping. He rummaged through the wardrobe and picked out a set of relatively simple T-shirt jeans from a pile of trendy clothes. He was not much higher than Qi Xiao and could make do with his size.
After changing his clothes, Ren Yi left Qi Xiao a note saying he had something to go first, then grabbed the key and went out of the door.
This time is the rush hour. Ren Yu is blocked in the third ring road. He looks at the car dragon in front of him impatiently. He picks up his mobile phone and sends a message to Gong Yingxian: it's a little blocked. I'll be there in a minute.
On the way, Ren Ying received a call from Zhang Wen and sent back the sample results of laboratory testing. It was really gasoline. Ren Ying asked Zhang Wen to come again. They wanted to look for clues that could help them find the murderer at the scene.
Just ten kilometers away, Ren Yu drove for more than 40 minutes. He saw Gong Yingxian's car outside Wanyuan community. He was relieved that he was still there.
Ren Yi climbed up the stairs and saw Gong Yingxian and several min policemen at the scene.
After seeing him, Gong Yingxian just glanced at him casually and turned away. Only a pair of beautiful eyes appeared on his face with a mask, hiding many emotions.
Ren Yi walked over: "the fire control laboratory confirmed that there was gasoline as combustion supporting agent at the gate of 2209, which was arson."
"Well, I already know." Gong Yingxian said.
"It is estimated that the neighbor on this floor set fire." Ren Yu looked around, "there were 12 households in total, and 2211 people died. The other households were also slightly and seriously injured. I don't know whether the arsonists ate the consequences of their own."
Gong Yingxian didn't respond, but focused on searching in 2209.
Ren Yu followed him and continued, "the arsonist may just want to revenge 2209, but he didn't expect to cause such a big fire."
Gong Yingxian still didn't speak.
Ren Yu was helpless and stood in front of Gong Yingxian, forcing Gong Yingxian to look at him.
"Why, Dr. Gong, are you angry with me?" Ren Yu looked at Gong Yingxian in bewilderment.
Gong Yingxian said coldly, "I don't have that time."
"Didn't I arrive a little late? It's rare for me to take a holiday. It's human to have a drink and indulge." Ren Yu joked, "you're not."
Gong Yingxian bypassed him and went to the kitchen of 2209, looking for something.
"You... What are you looking for?"
"Coffee machine."
"What?"
Gong Yingxian turned over the burned kitchen carefully, frowned and thought for a while, then went to the bathroom and continued to find something.
"What are you looking for now?"
"Electric toothbrush."
Ren Yu was even more confused: "what are you going to do?"
"Instead of talking nonsense, you'd better find it with me."
Ren Yu had to find it with Gong Yingxian, but only found half of the plastic toothbrush handle under the burnt down bathroom cabinet.
Gong Yingxian also put the toothbrush handle into the evidence bag.
Ren Yu was a little upset: "what are you doing? At least say it. I know everything when I help you."
Gong Yingxian finally looked straight at Ren Yu and said expressionless, "I found some domestic garbage that may not belong to the family in the pile of burning garbage at the door."
"For example?"
"I observed that the living standard of this family is not high. There are no new electrical appliances worth noting at home. Even the washing machine is old-fashioned." Gong Yingxian lifted the bag in his hand, "but there are coffee grounds, electric toothbrush replacement heads and so on in that pile of garbage."
Ren Yu's eyes lit up: "Wow, you observe so carefully, so the pile of garbage at the door doesn't belong to the family?"
"Part of it. My colleagues have visited some neighbors and confirmed what Xue Fei said. The family often piles garbage at the door. Later, they may deliberately want to be right with their neighbors and often save it for several days or even a week or two."
"Then why is there garbage at the door that doesn't belong to their family?"
"This can only ask the murderer."
Ren Yu thought, "there's surveillance downstairs, isn't there any clue?"
"Just got back to the branch, my colleagues are watching." Gong Yingxian said, "can you draw a fire spread map for me according to the scene? It's not in the house, but on the whole floor. The direction of fire spread may explain a little bit."
"Yes."
Gong Yingxian took out his iPad, called up the floor plan of the building and handed it to Ren Yu.
Ren Yu took it over and went back to the corridor. He drew the direction and sequence of the fire according to the various traces left by the fire - the burning marks on the ground, the burning pits, the smoked shape and position of the wall, the falling ceiling and so on.
At the right time, Zhang Wen also arrived and checked with him.
After drawing, the three stared at the picture and fell into silence.
"Strange..." Ren Peng looked at the window at the end of the corridor. "2209 is on the west side. When the fire starts, it should first spread towards the ventilation window on the west side. How can it spread to the East in turn? The fire on the west side burned through the ceiling."
"How do you know that the fire on the west side burned through the ceiling?"
Ren Yu picked up a gypsum board: "it's very simple. If the ground on the west side catches fire first, then the ceiling will be blackened after going up the wall. When the ceiling falls, the landing side will be black, and at the same time, it will fall on other combustibles. But this gypsum board..." he turned over the scorched gypsum board, but the back is snow-white, "Not only is there no smoke trace on the landing side, but there is no combustor below, which proves that the fire burns in the ceiling and then falls to the ground, causing the ground to catch fire."
"How could this happen?"
Ren Zhuo shook his head: "because both sides were badly burned, and when I came to the rescue, I only acted on the east side, while the west side was too big to go because it was a fire. I preconceived that it was the west side that burned first, and the open window also confirmed this. But after looking at all the evidence, the fact is just the opposite."
"Why did this happen?"
"I only looked at 2209 yesterday and didn't look at the corridor carefully." Ren Yu said with some chagrin, "I'm careless. One of the possibilities I can think of is that the west window was closed at that time, so the fire will spread to the windows in the East corridor."
"Go and have a look."
The three men went to the window on the west side. The window had already been burned, leaving only the frame, and the glass was broken. If only judging from the current state of the window frame, the window is closed, but it does not rule out the possibility that the heat field pressure will top it.
"This window is used for ventilation. Generally, the corridor will not be closed except in winter." Gong Yingxian thought cableway, "if there is stinking garbage in the corridor for a long time, no one will close it."
Ren Yi took a deep breath: "someone closed it and wanted the fire not to spread to the west?"
At the same time, they looked back to the deep corridor. Who would be the arsonist in the six families in the west?
