Ren Yi looked at the burning ruins in front of him and forgot to breathe for a long time. Anyone would feel depressed in such an environment.

Gong Yingxian handed him his foot covers and gloves: "Go and take a look."

After Ren Yi put it on, he walked over step by step.

There are many police blockades and evidence marks here. While looking at the photos, Ren Yan restores the original location of some evidence based on the situation on the scene.

Following the various burning traces, Ren Yi first analyzed the site roughly. This is a very simple fire scene. The key points of gasoline-ignition-combustion, fire point, combustion aid, and spreading direction are also very clear. The overall situation is not different from the report of the Fire Adjustment Department.

Ren Yi was a little disappointed and stood at the fire point in a daze.

Gong Yingxian walked to him: "How is it, have you found anything?"

Ren Yi shook his head and said unwillingly: "I'll read it again."

Ren Yi carefully investigated the scene again. He found a special trace under a pile of burnt clothing. It was a square burn mark that was only the size of a palm and not very complete. This was a very difficult trace to be discovered. The first is because it was under the clothes, and the second is because it was covered by a combustion aid. Since the burn marks and pits where the combustion aid passed were particularly obvious, it seemed very shallow.

Originally, this trace was nothing special, like something like a switch or socket, but Ren Yi remembered that there seemed to be nothing similar in the photo of the evidence. He looked through the photo again, but he did not find it.

Gong Yingxian squatted down: "What is this?"

"Not sure." Ren Yi said, "It looks a bit like a switch socket, but there is obviously no ground plug here. The key is that there is no similar shape in the evidence. It may be washed away by water when extinguishing the fire." Due to the strong momentum of the fire, the fire water gun often washes away, destroying many things, especially those burned by the fire, which is already very fragile.

"Is there a possible wooden stake that supports the stall? This shelf is so heavy that maybe it needs additional emphasis."

“It is also possible.”

"Let's look for it on the spot?" Gong Yingxian finished speaking, looked at the overfire ruins of hundreds of square meters, and took a breath.

Ren Yi sighed: "Flip around nearby."

The two of them turned around for a long time, but they couldn't find anything of similar shapes, but they had other gains. They found some incomplete shoe prints a little far from the fire point.

The reason why it is said to be shoe prints rather than footprints is because the footprints are marks of weight sinking, but the shoe prints will show the pattern of the soles. This mark is that some have shoe print patterns, while some only have marks of sinking.

Ren Yi immediately became alert because the shoe prints definitely did not belong to fire extinguishers or investigators. The firefighters' boots were in a unified manner. He knew the sole patterns of each shoe. Investigators - whether they were policemen or fire department - would wear gloves and shoe covers to protect the scene. The fire point here is the opposite direction, not the place where the investigators focus on investigating.

These shoe prints are strange, one by one, and sometimes disappear and appear, spreading to the exit.

"These shoe prints must have appeared later. It is impossible for such important traces to be missed during the on-site investigation." Gong Yingxian said in a deep voice, "Someone has been here at night."

"Didn't you send someone to the scene?"

"I stayed for seven days, but later I was too short of people, so I retreated." Gong Yingxian frowned, "These traces are so strange. I suspect that the person who came brought a shoe cover, but the shoe cover was scratched by the things on the scene, and he himself did not notice it."

Ren Yi suddenly understood: "Yes, that's it, otherwise it would be impossible to leave such strange traces."

"Come with me."

The two left Building A, and Gong Yingxian took Ren Yi straight to the nearest trash can. When they walked to the trash can, Gong Yingxian raised his eyebrows and signaled Ren Yi to check.

Ren Yi took a deep breath, then held it in, rolled up his sleeves and turned his head back.

"In this kind of densely populated area, the garbage truck originally came once a day, but now it is blocked around, with only investigators and staff coming and going. These municipal trash cans may not have been cleaned for several days." Gong Yingxian explained.

Ren Yi flipped it over quickly, then stood up straight, and gasped: "No."

"Let's go around the building."

Although Ren Yi was unwilling to flip through the trash can, especially unwilling to flip through it alone, he knew that "Miss Gong" would not do anything.

He followed four trash cans in a row, and Ren Yi took out a pair of shoe covers from inside, and a hole was scratched at the bottom of the shoe cover.

Gong Yingxian opened the plastic bag containing the evidence: "Sure enough, someone has come here, but I don't know if it's the one who sets a fire."

"He is coming, it must be you who have removed the person and you will pick it late at night. If you search the cameras in several nearby streets, you should be able to find people."

"Well, this range suddenly narrowed a lot." Gong Yingxian smiled coldly, "It really left a flaw."

"But what is he doing when he comes back? Take photos? Live broadcast? It's too risky. When the task force is keeping a close eye on this case, he still takes such a big risk for a little money?"

"You are right. This risk is too great. It should not be for money." Gong Yingxian thought, "In this case, the biggest possibility is to destroy the evidence."

Ren Yi cursed: "How did this person know when the police retreated, and what evidence was to destroy."

"It can be seen that he is very careful. He is an arsonist with anti-reconnaissance consciousness. He didn't even notice that the shoe cover was broken." Gong Yingxian's eyes sank, "He knew that he would go back to the scene to destroy evidence, and knew when the police would withdraw people. He was an insider."

Ren Yi felt his hands trembling. He couldn't imagine how penetrating the organization was. There was obviously an insider in the case nineteen years ago. Now they are facing the same dilemma?

Gong Yingxian's face looked very ugly: "Although this shoe print is incomplete, it is enough to find out the style of the shoe. We have a very complete shoe print database. After checking the shoe samples, I will compare it with all the case handlers."

Ren Yi clenched his fist and suddenly kicked it hard on the trash can. He kicked it several times in anger, and the churn rage in his heart could not calm down.

In the end, Gong Yingxian pulled him: "Enough, you still have injuries on your body, don't do violent movements."

Ren Yi turned his back and tried hard to digest the hatred of wanting to kill people.

He can be calm and objective in other arson incidents because he was ordered to be calm and objective, but this incident killed his brother, and the resentment in his heart never really subsided, like a restless volcano. Originally, the police were their biggest hope, but now they found that this hope may not be reliable. How could he not be angry or disappointed?

Gong Yingxian looked at Ren Yi's back, but didn't know how to persuade him, so he could only stand by in silence.

After a while, Ren Yi calmed down his emotions. He turned around and looked at Gong Yingxian apologetically: "I'm sorry, I'm not angry with you."

Gong Yingxian reached out and grabbed Ren Yi's neck, pressed his head on his shoulder, and said in a gentle tone that he hadn't noticed: "I understand you."

Psychology divides the process of sadness into several stages. Although there are different opinions, anger is a very important and necessary link. It has not been too long since the incident happened, and Ren Yi's anger is far from over. It just tries to suppress it. No one understands the pain of losing an important person better than him.

Ren Yi used his forehead to drill Ren Yi's shoulder hole, enjoying this moment of peace and warmth.

After all, the two of them were on the main road and didn't dare to get tired of it for too long, so they quickly separated.

They returned to Building A, extracted evidence of footprints, and carefully checked the scene, and did not leave until the sky became dark.

Gong Yingxian sent Ren Yi back to the squadron, and they were also communicating the case on the way.

When he arrived at the door of the squadron, Ren Yi sniffed Gong Yingxian's face and said reluctantly: "I guess it will be the New Year next time we meet."

"Well, it's been a few days. You should be extra careful during this period."

"Don't worry, so are you." Ren Yi smiled, "Then I'll leave."

"Wait a minute." Gong Yingxian's expression was obviously hesitant.

"What's wrong?"

Gong Yingxian paused and took out a file bag from the storage box. "This was sent to me by the hospital two days ago. It was about your father's second stage treatment plan. It requires your signature. It should have been sent directly to you, but..."

"Oh, okay." Ren Yi thought about his condition a few days ago. Even if he sent it to him, it would be useless. He picked up the pen and signed it directly.

Gong Yingxian opened her mouth, and a struggling look flashed in her eyes: "Don't you look at it?"

Ren Yi flipped it out a few times and said with a smile: "This ghost can understand it. I know every word and don't even know it. Anyway, the first stage is very effective, and your doctor is really awesome, thank you."

Gong Yingxian said "Yeah".

Ren Yi stared at Gong Yingxian deeply: "I was really uncomfortable just now, but after thinking about it, even if there are unreliable people in the police, I believe you, you will definitely catch the beasts raised by the bastard, avenge your family, my brothers, and those innocent and innocent people who died in vain."

Gong Yingxian's lips trembled slightly, and he nodded slowly.

"See you during the New Year." Ren Yi got out of the car, waved his hand to Gong Yingxian before entering the squadron.
