Ren Yi and Qi Xiao went to have a meal first and watched a movie. At night, they each called a few friends to party at the bar they often went to.

In fact, Ren Yi likes to drink very much. Although he doesn’t drink too much, he is strictly prohibited from drinking when he is diligent. It is rare to have a holiday, so he naturally needs to relax.

After playing until midnight, a group of talents gradually dispersed. Ren Yi drank a lot, but he could still walk steadily, but Qi Xiao hung it on him staggeringly.

When he walked to the car, Ren Yi freed up one hand to take out his cell phone: "Wait, I'll call a designated driver."

Qi Xiao hugged Ren Yi's neck, raised his head, put his warm lips on, and kissed Ren Yi lightly.

Ren Yi hugged his waist and said vaguely: "Okay, okay, let's go home first."

Qi Xiao stared at Ren Yi with his misty eyes and whispered: "Brother, you are so nice, very good."

"Well, I know." Ren Yi smiled, "What's wrong with you? This is."

"Actually... I want to be with you seriously." Qi Xiao said drunk, "But I feel that now... nothing is there, not popular, and have no money, so I am not qualified to fall in love."

Ren Yi comforted him: "You are only 23, why are you in a hurry? You will definitely become famous." He placed an order on the software and waited for the designated driver to come.

"Now those kids, who are teenagers, are just snatching him, are you snatching him from the entertainment industry." Qi Xiao rubbed his cheek against Ren Yi's face, "Just just chatting with you, at the age of 18 or 19, are you... going to be snatched away by the young ones too?"

"Just talk nonsense." Ren Yi laughed, "I'll send you back and have a good sleep."

"You...why are you not in love?"

"I don't have time."

Qi Xiao looked at Ren Yi with a silly smile: "How about... let's try?"

Ren Yi rubbed Qi Xiao's hair and said softly, "Let's talk about it when you sober up." It's not that he doesn't want to fall in love, but he knows that he and Qi Xiao have too many differences from background to pursuit to values, and they may not be able to talk about feelings.

Qi Xiao hugged Ren Yi's waist, hung his whole body on him, his face buried in his chest, and slowly rubbed it like a well-behaved cat.

After a while, the driver arrived. Ren Yi brought Qi Xiao into the car and found that the person was asleep.

He asked the driver to drive the car to Qi Xiao's home.

----

When it was just dawn, Ren Yi was woken up by the phone. He grabbed the phone on the bedside table in a daze, put it in his ear, and "feed" it in a hoarse voice.

I paused on the other end of the phone: "Why are you still sleeping at this point?"

Gong Yingxian's cold voice poured on Ren Yi's face like a bottle of cold water, which immediately made him wake up a little. He forced his eyes to open: "What time is it, what time is it?" After asking, he looked at the screen of his phone himself, and it was almost nine o'clock.

"You've drunk." Gong Yingxian's voice was obviously a little unhappy.

"Ah, I drank very late last night with my friend." Ren Yi got up, "I haven't woken up so late for a long time... What's wrong?"

"Forget it." Gong Yingxian simply hung up the phone.

Ren Yi was stunned for a long time when he finally came to his senses. He remembered that the two of them had made an appointment to go to Wanyuan Community again yesterday. The blockade at the fire scene could not be too long because it would affect the normal life of the people. This is different from a bar, so their time is limited.

He drank so much last night that he forgot.

Ren Yi pounded his head, got up from the sofa, and went to the bathroom to wash.

Last night he spent with Qi Xiao, after he put Qi Xiao on the bed, he was too sleepy to move, and fell asleep directly on the bed. When he woke up, he felt sore back and dizzy and wanted to vomit, which was a typical sequelae of hangover.

After he took a shower, Qi Xiao was still sleeping soundly. He flipped through the closet and picked out a relatively simple T-shirt denim from a bunch of trendy clothes. He was not much taller than Qi Xiao, and he could only get the size.

After changing his clothes, Ren Yi left a note for Qi Xiao saying that he had left in advance, then grabbed the key and went out.

This time was the peak hours of work, and Ren Yi was blocked on the third ring road. He looked at Che Long in front of him with annoyance, picked up his phone and sent a message to Gong Yingxian: It's a bit blocked, I'll arrive later.

On the way, Ren Yi received a call from Zhang Wen and sent the sample back to the laboratory for testing. The result was indeed gasoline. Ren Yi asked Zhang Wen to come over again. They wanted to find clues on the scene that could help them find the murderer.

In just ten kilometers, Ren Yi drove for more than 40 minutes. He saw Gong Yingxian's car outside the gate of Wanyuan Community and breathed a sigh of relief. Fortunately, he was still there.

Ren Yi climbed up the stairs and saw Gong Yingxian and several police officers at the scene.

After seeing him, Gong Yingxian just glanced at him casually, then turned her face, and only a pair of beautiful eyes appeared on her face wearing a mask, hiding a lot of emotions.

Ren Yi walked over: "The fire regulation laboratory confirmed that there was gasoline at the door of 2209 as a combustion aid, which was arson."

"Well, I already know." Gong Yingxian said.

"It is probably the neighbors on this floor who set the fire." Ren Yi looked around and looked at it. "There are twelve households in total, and 2211 people were also dead. The other households were also a little bit minor and seriously injured. I wonder if the ones who set the fire also suffered the consequences."

Gong Yingxian did not respond, but just focused on 2209.

Ren Yi followed him and continued, "The one who set the fire might just want to take revenge on 2209, but he didn't expect it to cause such a big fire."

Gong Yingxian still didn't speak.

Ren Yi was helpless and stood in front of Gong Yingxian, forcing Gong Yingxian to look at him.

"What are you doing, Dr. Gong, are you angry with me?" Ren Yi looked at Gong Yingxian in confusion.

Gong Yingxian said coldly: "I don't have that time."

"I'm just a little late? I have a rare vacation, and it's normal for me to drink some wine to indulge it." Ren Yi teased, "You won't be."

Gong Yingxian walked around him and walked to the kitchen of 2209, searching for something.

"You...what are you looking for?"

“Coffee maker.”

"What?"

Gong Yingxian carefully flipped through the kitchen that was burnt beyond recognition, frowned and thought for a while, then walked towards the bathroom, and continued to look for something.

"What are you looking for now?"

“Electric toothbrush.”

Ren Yi was even more confused: "What the hell are you going to do?"

"Instead of talking nonsense, you might as well find it with me."

Ren Yi had to find Gong Yingxian, but only found half of the plastic toothbrush handle under the burned bathroom cabinet.

Gong Yingxian also put the toothbrush handle into the evidence bag.

Ren Yi was a little unhappy: "What are you doing? At least I will say anything. I will tell you everything when I assist you."

Gong Yingxian finally looked at Ren Yi with his direct eyes and said expressionlessly: "I found some domestic garbage in the pile of burning garbage at the door that may not belong to this family."

"for example?"

"I observed that the family's living standards were not high. There were no emerging appliances worth noting at home. Even the washing machine was old-fashioned." Gong Yingxian carried the bag in his hand, "but there were coffee grounds, electric toothbrush replacement heads and other things in the pile of garbage."

Ren Yi's eyes lit up: "Wow, you observe so carefully, so the pile of garbage at the door is not owned by this family?"

"Part of it. My colleague has visited some neighbors and confirmed what Xue Fei said. The family does often pile up garbage at the door. Later, they may have deliberately wanted to go against their neighbors. They often save for several days, or even a week or two before throwing them away."

"Then why is there any garbage at the door that does not belong to their house?"

"This is all I can ask about the murderer."

Ren Yi thought for a while: "There are surveillance monitors downstairs. Are there any clues?"

"Just just took it back to the branch, my colleagues were watching." Gong Yingxian said, "Can you draw a picture of the fire spread for me based on the scene? It's not in the house, but from the entire floor. The direction of the fire spread may explain a little."

"Can."

Gong Yingxian took out his iPad, called out the floor plan of the building, and handed it to Ren Yi.

Ren Yi took it over and returned to the corridor. Based on the various traces left by the burning - the burning pit on the ground, the smoky shape and location of the wall, the drop of the ceiling and other evidence of silence at the scene after the fire, the direction and sequence of the fire spread were drawn.

Just as Zhang Wen arrived, he also checked with him.

After the drawing, the three of them stared at the picture and fell into silence.

"Strange..." Ren Yi looked at the window at the end of the corridor, "2209 is on the west side, and the fire should be spreading towards the ventilation window on the west side first. How could it spread to the east side? The fire on the west side burned through the ceiling."

"How do you make sure the fire on the west side burned through the ceiling?"

Ren Yi picked up a piece of plasterboard: "It's very simple. If the ground on the west side catches fire first, then the ceiling will be blackened after it is put on the wall. When the ceiling falls, the side that hits the ground will be black, and at the same time, it will fall on other burning objects. But this plasterboard..." He turned over the charred plasterboard, but the back is snow-white. "Not only does there be no smoke on the ground, but there is no burning objects below. This proves that the fire burns in the ceiling and then falls to the ground, causing the ground to catch fire."

"how so?"

Ren Yi shook his head: "Because both sides were burning very seriously, and when I came up to rescue, I only operated on the east side. The west side was the fire point and the fire was too big and could not be overcome. I preconceived that it was the west side that burned first, and the open window also proved this. But after checking all the evidence, the facts were exactly the opposite."

"Why does this cause?"

"I just looked at 2209 yesterday and didn't look at the corridor carefully." Ren Yi said with some annoyance, "I'm careless. One of the possibilities I can think of is that the window on the west side was closed at that time, so the fire would spread to the windows on the east side of the corridor."

"Go and take a look."

The three of them walked to the west window. The window had been burned to the point where only the frame was left, and the glass was broken. If we only judged from the current state of the window frame, the window was closed, but the possibility of the heat field pressure pushing it up is not ruled out.

"This window is for ventilation. Generally, the corridor will not be closed unless it is winter." Gong Yingxian thought, "If there is foul stinking garbage in the corridor for a long time, no one will close it."

Ren Yi took a deep breath: "Someone shut it down and wanted the fire not to spread westward?"
