The room of the task force was dark, only the lamp on Lin Zifan's desk emitted a faint light, the police are also people, and they have to go home after work, even if they stay in the office overnight, the murderer will not come out by himself.

"Team Qin, I didn't go home."

I was nestled in a chair, looking at the ceiling, and Lin Zifan walked into the office with a file in his hand.

"I'm the only one to go home, and it's the same everywhere." I lifted my coat and staggered to my feet: "Why didn't you come home?" ”

Lin Zifan's desk was across from me, and he stretched out a big stretch towards me. "It's like I'm not going home alone."

We looked at each other for a few seconds, and suddenly we all laughed.

In fact, there is nothing funny, it's just that two bachelors take the initiative to work overtime in the office, and we look at each other's pitiful appearance, and we want to laugh inexplicably. Sometimes, a man's happiness is as simple as that.

He took out a box of cigarettes from his pocket, took one out and threw it to me, a brand I smoked.

Sometimes men know each other better than couples, at least we don't have to dig out to guess each other's preferences.

Lin Zifan lit it himself and threw the lighter to me. In the dim light, this familiar action made me feel like I was traveling, and I couldn't help but think of my good brother Ye Yun, who would throw it to me like this when he was still there. I haven't touched a cigarette since his whereabouts are unknown.

It's been three years, I hope he's still alive......

"What's wrong, Team Qin? Got something on your mind? Lin Zifan spit out a smoke ring, and saw that I was a little uneasy.

"It's not that this case is too troublesome, the case will be solved within a time limit, and after tonight, as soon as the morning dawns, it will be the fourth day." I let out a long sigh and lit my cigarette.

"This case is much more complicated than I imagined, I thought that Zhou Li could make any progress in solving the case, but in the end, Zhou Li can only be regarded as an unexpected gain."

After Lin Zifan finished speaking, he took out a report from the file bag and handed it to me: "Zhou Li's criminal responsibility capacity judgment report has come out." ”

According to the report, Zhou Li was judged to be a mentally ill person with limited capacity for criminal responsibility, which, judging from the current facts of the case, constitutes the crime of insulting a corpse, and what awaits him will be a trial of the law.

"Team Qin, you have solved a lot of cases, have you encountered such a situation?" Lin Zifan extinguished the cigarette in his hand and suddenly asked me.

He is now the head of the criminal police, and my current position is in the Public Security Section, although I am in the task force, but according to the procedure, I can only be regarded as a supernumerary member of the criminal police team. But Lin Zifan still chatted with me as a modest junior as usual, which made me a little embarrassed.

"I've solved a lot of criminal cases in the past, most of them are not so complicated, the murderer will leave clues at the scene, and the suspect can be easily locked through the crime tools. The reason why the current progress of this case is slow is the lack of key clues of the tools of the crime, although the suspect has been locked up, Liu Yan's hands are crippled, and he cannot complete the ...... of disembowelment."

I was just halfway through my sentence when a strange thought crossed my mind.

"You say...... Will the murderer not use his hands......"

In the middle of the night, there was silence in the office of the task force, and I suddenly leaned on my desk and poked my head at Lin Zifan opposite, and the scorching light hit my expressionless face, which looked particularly gloomy.

Lin Zifan didn't understand what I meant, and burst out laughing: "You don't use your hands, do you use your feet?" ”

"Some people's feet are indeed more flexible than their hands." I said coldly.

Lin Zifan's smile slowly froze, and he also leaned on the table and poked his head out: "Murder with your feet? Wouldn't it be outrageous? ”

"After eliminating all the impossible, the rest is the truth, no matter how inconceivable."

There was a dead silence in the office, and even the air began to freeze.

"Don't be crazy about me! I'm just a legend! "A cell phone rings and startles both of us.

"Lao Qin, have you slept, hurry up, there is a change in the corpse." Ren Qiushi's voice came from the phone.

This Ren Qiushi, although the smell of corpses on his body is relatively strong, can give me new clues at every critical moment.

"I'm in the office, and I'll get there."

In the dissection room of the forensic department, Zheng Pingping's body was lying on the planing table again, only this time, Zheng Pingping had a head.

The corpse has been refrigerated and embalmed in accordance with regulations, and it does not appear to show any obvious signs of decomposition. The flesh and skin tissue of the anterior chest incision is inactive and takes an eversion shape.

"The musculature of the body was still elastic when the person just died, and the murderer wanted to disembowel the internal organs, so he would inevitably use his hands to tear the incision to the sides to create more space, and acupressure marks were also found during the initial autopsy, but no fingerprints were found."

Ren Qiushi said unhurriedly, his perennial forensic career has allowed him to develop this kind of patient character, and Lin Zifan and I stood aside and waited for him to continue.

He pointed to the incision on the front chest of the corpse with his gloved fingers, because the corpse had shown stiffness and the skin muscles were inactive, so the original acupressure marks were more obvious, and it was obvious that there were four finger prints on both sides, and there were obvious signs of decomposition.

"What do you mean by mutation?" I asked him directly.

"The level of decay of the entire corpse was consistent, except for the accelerated decomposition of the acupressure, which seemed to be caused by some kind of accelerated decomposition, most likely catalyzed by chemical agents. When the murderer committed the crime, it is very likely that his hands were contaminated with some kind of catalyst. ”

Ren Qiushi's expression was solemn, he had known him for so many years, and he had never seen him show such an expression, he shook his head: "I don't know the ingredients of this catalyst, and this is the first time I have encountered this situation." ”

With what I know about him, he would never contact me urgently in the middle of the night when he encounters such a problem, and he must have found something else.

Ren Qiushi looked at me in a daze, as if waiting for my question.

After a while, he looked at me and shook his head, and took the initiative to say his new discovery: "Lao Qin, Lao Qin, you still give me a little face, come on, look at this." ”

He waved his hand at me, and I walked slowly to the dissecting table, the smell of corpses on his body was so strong.

"Look at this."

Looking in the direction he was pointing, I found four blackened fingerprints next to each other in the incision on my chest.

"What's so strange about that?" I frowned.

"You're still an old detective, can't you see anything strange?"

He straightened up and looked at me in a swaggering manner. Well, this time it's you who wins.

I shook my head.

"When people tear things hard, they need to fix them with both hands, and the whole arm exerts force, and at this time, in order to have a larger support point, the hands will definitely open their five fingers, bend their fingers, completely buckle the target, and tear vigorously. And the guidance presented by this corpse, with the limbs together and the gaps not large, and the fingertips clasping the target, and the thumb and the rest of the limbs exerting force in the same direction, is not anatomical or mechanical. ”

Things that were originally quite easy to understand became complicated when he said them, and I didn't listen to him analyze them slowly, so I asked him directly: "What is your conclusion?" ”

"After studying the acupressure marks, these are not human hands."

Ren Qiushi came up with a shocking conclusion.

"What's that?"

"It's a pair of feet."
