This last sentence was asked without warning and had nothing to do with the previous conversation. This is Qi Yuanchang's ability as an old policeman———— first paralyzing with ordinary topics, and then suddenly throwing out the core of the problem. Caught off guard, some clues can be seen from the interlocutor's reaction.

Liu Tianming felt his heart sink suddenly, but his facial expression was controlled by a strong concentration. He looked at Qi Yuanchang with blazing eyes in amazement: "Chicken farm? What chicken farms? ”

Qi Yuanchang was a little disappointed.

Mr. Liu's reaction apparently showed that he had nothing to do with the chicken farm.

If he had been to the chicken farm last night, his expression would have been diametrically opposed to the answer.

Thinking of this, Qi Yuanchang sighed secretly and said lightly: "Not far from Wu Jian's residence, there is a chicken farm. Last night, someone found Wu Jian's body there. ”

"You, what did you say? Wu Jian is dead? ”

Liu Tianming suddenly stood up from his chair, his eyes widened, his face was full of disbelief, and his speech became a little hurried: "He, why did he die?" ”

Qi Yuanchang carefully observed the changes in Liu Tianming's expression, and continued to induce the conversation: "Wu Jian was twisted off his neck and was stabbed more than a dozen times. The wound was deep, and the knife was fatal. The murderer's modus operandi was extremely brutal. We have seen the surveillance footage of the chicken farm, and at about ten o'clock last night, someone entered through the gate. That man is about the same height and physique as you. What do you go to that kind of place? ”

As soon as these words came out, Liu Tianming's nervous mood suddenly became relaxed.

He was sure that the Fu'an chicken farm did not have any surveillance cameras at all.

When he walked into the chicken farm last night, Liu Tianming had already sensed that danger was approaching. He was very meticulous in his surroundings and did not notice the presence of any surveillance equipment. From this, it can be determined that the old policeman who is sitting opposite him with a kind smile towards him is really difficult to deal with.

As for the statement that Wu Jian was stabbed more than a dozen times, it is even more false.

Liu Tianming's face was full of confusion: "What chicken farm?" I don't know! I haven't been there at all. I left the rental house last night and went straight home. ”

Liu Tianming has absolute confidence in his own rhetoric. Zhang Zhiqiang, a security guard in the community duty room, is the best witness. What's more, although he was very frightened last night, he had the best alibi in the panic.

It's so fast to run all the way back from the rental house. Liu Tianming usually likes to read mystery detective novels. He knew very well that the location of the Fu'an Chicken Farm was remote. Although it is not far from the city, the dirt road outside the chicken farm is very narrow and can only accommodate one car.

Last night, Liu Tianming found no cars in the Fu'an chicken farm. In other words, even if a car goes in and out, it should have happened after you left. Although the dirt road is only about two kilometers long, there are no lights along the way, and the ground is uneven. Liu Tianming obtained his driver's license two years ago and knows that driving on this kind of road is very skilled. With a little bit of speed, the stone clods will scrape through the chassis of the car. In short, it takes at least half an hour to drive back and forth on that stretch of road.

This conversation was doomed to nothing.

Qi Yuanchang didn't see any discouragement or anger on his face. Still smiling, he politely said goodbye.

Huang He was very excited. This means that old classmate Liu Tianming is not a criminal suspect. After the two left each other's contact information, Huang He left the hospital with Qi Yuanchang.

Sitting in the driver's seat of the police car in the parking lot and closing the door, Huang He smiled at Qi Yuanchang, the captain who was sitting in the passenger seat, and said: "Team Qi, I'll just say, this old classmate of mine will definitely not commit murder." You saw it at the entrance of the hospital before, hey, hey, hey! Be brave and courageous! ”

Qi Yuanchang didn't say anything, just took out a cigarette from his pocket, lit it, smoked it silently, and fell into deep thought.

Before coming to the hospital, they had already gone to the community where Liu Tianming lived and found Zhang Zhiqiang, the security guard on duty last night. Zhang Zhiqiang remembered Liu Tianming's return time very clearly, and even accurate to the specific minute and second numbers. It's not that Zhang Zhiqiang has an extraordinary memory, but the mother-in-law who drove Aoqi Q7 last night was really annoying, and the numbers on the parking card were firmly fixed at that time. Even another community security guard who was more than ten meters away at the time still remembered this incident vividly.

The journey from the rental house to Mr. Liu's residence takes about 20 minutes each way by taxi. Security guard Zhang Zhiqiang saw that the time when Liu Tianming came back and the time when Wang Fushou, the owner of Fu'an Chicken Farm, was attacked, and the interval was almost so long.

There were no vehicles coming out of the Fu'an chicken farm last night. The colleagues in the Trace Identification Division of the police station have already reached a conclusion on this point. The ruts on the dirt road outside the chicken farm were left four days ago.

This means that if Liu Tianming is the murderer, then he must leave the chicken farm on foot after the murder before he can return to the road near the village to take a taxi.

The time provided by security guard Zhang Zhiqiang is evidence that cannot be bypassed. If you want to complete a series of actions such as killing and running away in this time period, even if you are an Olympic sprint champion, Bolt the Flyer cannot do it.

Also, Wang Fushou, the owner of the chicken farm, is too picky. In order to save costs, he did not install any monitoring equipment at all. If there were surveillance footage, then this case would not have been so nerve-wracking.

All kinds of evidence show that Liu Tianming cannot be the murderer. Moreover, his performance today is also completely in line with the logic of an uninformed person. However, Qi Yuanchang still felt that things were not so simple.

It's not about the evidence, it's purely a gut feeling on your own.

Thinking of this, Qi Yuanchang took a deep breath of cigarette and said calmly to the Yellow River: "Walk around with your old classmate more." Maybe he'll remember something he hasn't told us about. Well...... Let's drive! Now that I'm back in the game, I should still be in time for lunch. ”

……

Liu Tianming sat in his office, looking through the window at the police car that had just driven out of the hospital gate, and exhaled secretly. It was only now that he realized that his palms were full of sweat.

A lot of things that happen unintentionally and accidentally, put together, become a completely different thing.

Liu Tianming doesn't know how long he can maintain this state?

The black body in the morgue has not been claimed, and the police station has not been able to find any information about the identity of the deceased.

Xiao Wu was bitten to death by me, and I also sucked all the blood in his body.

I'm infected by the virus now, will I become like Xiao Wu?

Fear was so intense that it suddenly came out of the depths of my brain. Liu Tianming felt a slight dizziness. He cheered up, walked to the desk and sat down, opened the computer on the counter, and clicked on the browser, hoping to find something relaxing to look at and soothe his overly tense nerves.

Baidu's search window is very eye-catching on the browser. I don't know why, Liu Tianming suddenly had the idea of looking it up and trying his luck. He quickly typed the keywords "black corpse", "unnatural death", "hunger", and "sugar" in the search column.

There are many sub-columns that have been found, and there are dozens of pages.

Liu Tianming clicked on a few and found that they were all advertising websites that were tricked into tricking viewers into watching. The content is either someone digging up black zombies in the wild, or a picture of a hungry African man skinny. It is mixed with a large number of pictures of bare-assed and fat-breasted beauties scratching their heads and posing. There is also a huge advertisement for a certain magic oil and a certain miracle medicine next to it. The advertising words are also shocking: you will be bigger, thicker, stronger! Just give it a try and you'll find that you're a powerful human drilling machine!

There are still more than 20 minutes before the afternoon work time. Except for Liu Tianming, there was no second person in the room. He continued to search his computer for materials and information that might be useful to him. Web pages are opened, briefly viewed, and then closed. Liu Tianming felt that his thinking and visual nerves had become numb———— there were so many advertisements and garbage that he almost wanted to vomit when he saw it.

The Baidu search engine has turned to page forty-eight. Just when Liu Tianming was about to give up the search and go downstairs to take a breath, he suddenly saw a line of words that interested him appeared on the page he had just clicked on.

"There are many causes of death under abnormal circumstances, and it is very rare for a body to turn black within 24 hours. Death in the conventional sense of the human term usually refers to the death of the brain. However, the cells in the deceased's body can still survive for a longer time after the brain dies. The specific time limit depends on the amount of energy converted by the remaining sugars in the deceased's body. ”

Looking at this short text, Liu Tianming narrowed his eyes slightly.

As an undergraduate medical student, Liu Tianming certainly understands the difference between brain death and cell death. According to the current accepted theory in the medical community, after a human being is recognized as dead, his body is still in an intermediate state of life and death for a certain period of time, which is what the professional term calls "intermediate life". The more cells or organs that need oxygen, the faster it will die completely.

In other words, the survival time of human cells is fundamentally related to oxygen.

The reason why the word "sugar" was entered in the search column was completely a whim of Liu Tianming. Since that time when I went out with the ambulance to receive patients, both I and Xiao Wu have become fond of candy, and last night we found a large amount of candy wrappers in Xiao Wu's rental house.
