The professional quality of the male protagonist

As a result, there were basically countless results on the first day. Li Yancheng carefully read the materials from beginning to end, and Zhang Xuan remembered watching the surveillance videos brought back a few times, but he didn't gain anything.

The information Li Yancheng read before was all investigated by the police before, so he couldn’t see much. The investigation is not to say that it is useless, on the contrary, it is very useful, allowing Li Yancheng to understand the whole story of this incident. clear.

But those data are very formulaic, perhaps because the investigation was divided into several groups before, and after some deletions, what Li Yancheng has in front of him is basically some very objective data statistics.

However, the investigation of the case does not result from sorting out all the information. This is not a simple addition and subtraction.

Zhang Xuan checked all the surveillance videos at the time of the incident that day, but found no one worth noting, so he extended the time by 24 hours for the second time, and began to look at the 24 hours before and after the incident. surveillance video.

Maybe the murderer deliberately staggered the time to avoid being discovered, but Zhang Xuan's idea has not been verified. He has watched all the surveillance videos back and forth many times, but he has not found anyone suspicious. .

There are a lot of people living in the community. Those old, weak, and young who were excluded by Li Yancheng, and the remaining qualified people Zhang Xuan has noticed. Although there are many people walking back and forth at the door every day, they can carry the blood Not many went out.

However, in this way, some people were excluded. Those who happened to be at the door at the time of the incident were basically not suspected of committing the crime.

But there are too many people in the community, even after such exclusion, there is still a huge number left.

Fortunately, around 7:[-] the next morning, Aman and several other people arrived here one after another.

After agreeing to meet at the restaurant at the gate of the community, Zhang Xuan quickly led a few people back to the office.

Several of them had known about this case before, and Zhang Xuan had also sent them relevant documents to let them have a look first, so these people had all heard of the legend of vampires.

After arriving here, except for his younger brother Ye Zhong, who looked a bit ugly, the rest of the people didn't react too much.

After all, if you believe in something, it works, but if you don't believe it, it doesn't work. Not everyone believes in vampires.

When An Xiang saw that he had found a similar person, he immediately developed a good impression of Ye Zhong, and was very relieved when he saw Ye Zhong.

His brother Ye Kai was a little funny when he saw this. In the office, seeing two people sitting together on the sofa, Ye Kai said: "You two should use your brains, too. There are really things like vampires in this world." , why go to so much effort to cut these people upside down and hang them upside down, wouldn't it be enough to secretly bite and suck blood?"

After hearing Ye Kai's words, the eyes of the two people with ugly faces suddenly lit up, as if they felt that Ye Kai's words were very reasonable.

On the contrary, Ye Kai's complexion was even uglier.

Thinking about it, he probably never thought that these two people actually believed that there were vampires in this world.

Fortunately, Ye Kai didn't have much time to correct his younger brother's thinking, because soon there were tasks falling on him.

Zhang Xuan is still struggling with the surveillance video, so Ye Kai will take people to visit a few relatives and friends who are related to the victim to see if they have any news.

That cruel way of killing, although on the surface it seems to be for the blood in the opponent's body, but it cannot rule out the possibility that the opponent is pretending to draw yarn, because this kind of death is too cruel, not like ordinary murder case.

The wounds on Hu Xingfan's body are basically all fun, but he still needs to rest, so he didn't go to the field with Ye Kai, but was responsible for sorting out the rest of the information.

Li Si and He Xiuwen also came back that afternoon to join the investigation. The two of them were responsible for even more difficult tasks, because they had to check all the people in the entire community.

Although such an approach is no different from finding a needle in a haystack, fortunately, the site where the plan was issued this time is in the community, so although the investigation is extensive, it is not impossible to find the needle.

The two of them were too busy, so they specially called Zhang Xia and Ye Zhong over.

In this way, the only people left were Xie Wenyuan and Ye Zhong. Aman had already reported to the forensic department, and he had to go to the last crime scene himself.

After everyone's tasks were assigned, Xie Wenyuan and Li Yancheng sat down at the desk in the middle of the night, and in front of them were a huge number of documents.

Most of these are the files of some people in the community, and some are related to cooperation cases.

"What do you think now?" Xie Wenyuan asked.

In the beginning, he really didn't like Li Yancheng who appeared out of nowhere, but now this has changed.

Li Yancheng thought for a while, and roughly expressed his opinion, "I don't know why, so he has been committing crimes here and has not left. This may be some kind of wrong cognition, or self-suggestion. In short, he thinks he should not Get out of this neighborhood."

At the end, he added, "So he only committed crimes in the community, and even felt that he couldn't leave the community."

And this reason is likely to be the stimulus that made him become abnormal and start attacking the victim.

"Can't leave?" Xie Wenyuan pondered the meaning of Li Yancheng's words.

Xie Wenyuan didn't have much time to participate in the investigation, but he used to manage files, so he was no stranger to this kind of thing.

"What do you think the source of the stimulus will be? Illness?" Xie Wenyuan knew that Li Yancheng had asked people to check whether anyone in the community was seriously ill before, but such an approach was too general and somewhat confusing.

"I'm not sure yet, but I can't think of anything other than illness that can be related to my studies." Li Yancheng said frankly.

"Then do you think there is such a possibility." Xie Wenyuan hypothesized, "This may be a new type of crime of blood trafficking. As far as I know, so far the healthy blood types on the market are not cheap. "

Xie Wenyuan and the others were not playing around in the past. After hearing that Li Yancheng took over the case, they tried to understand this 'vampire' legend like Li Yancheng did.

The possibility that Xie Wenyuan thought of was blood trafficking.

Moreover, Xie Wenyuan's speculation is not without reason. At first, the victim was disembowelled, and some organs in his body were not found.

Ye Zhong stopped what he was doing and looked at Xie Wenyuan. Compared with the current strange rumors, the possibility proposed by Xie Wenyuan was obviously higher than them.

But Li Yancheng shook his head, "If it were me, I would not do this. First of all, the risk of doing so is too great. If it were me, I would want to obtain blood from other people's bodies, so I would not choose such a community. Instead, I will choose an ordinary community with a large number of people. First of all, such a community is not easy to be noticed, because there are more strangers coming and going every day. Secondly, I will not choose to commit crimes in the same community, because I will be caught in this way. The possibility of living is very high. I will choose to carry out selective attacks in multiple areas. Once I succeed, I will never go back. If the case cannot continue to be investigated, it will become a cold case. Usually, the validity period of the cold case will not be It’s too long, and no one will pursue it after 10 or 20 years.”

Ye Kai shuddered and stepped back.

Zhang Xuan, who was watching the surveillance video at the side, stopped what he was doing after hearing Li Yancheng's words, and turned around while pulling the stool.

"The most important point is that the blood in a person's body does not know the price. The blood in a person's body is at best, a few thousand to 1 yuan." Li Yancheng said, "The price of human blood in the black market is far away. It’s not as high as it is rumored, and most of the time this thing is worthless.”

The reason is simple, because it is not very difficult for you to get what you want.

Taking such a big risk for very little profit, if it is because of the blood trafficking that Xie Wenyuan said, it is really not worth the candle.

Xie Wenyuan thought about it for a while, and felt something was wrong. How could Li Yancheng know the price of human blood on the black market?

But before he could think about it, Li Yancheng said again: "Compared to selling human blood, I think it might be a murder like revenge. What method was used to gain the victim's trust, but if the other party wanted to cover up something in this way, then he did it very successfully."

"You mean that the murderer's purpose is actually only one of the victims, but in order to cover up the relationship between the victim and her, so he killed more people to cover up?" Zhang Xuan understood.

"So our focus of investigation is still on the community, centering on the community and spreading out, dividing the community into two districts and investigating separately. Investigate all the places where the murderer may appear one by one, as well as all the connections between the victim and the murderer .” Li Yancheng said.

"Speaking of which, there is one thing that is very strange. Do you remember what happened when we went to the building of the last victim?" Zhang Xuan said.

Li Yancheng nodded, and then he went several times to check the scene.

Zhang Xuandao: "The first time I went there, I saw a lot of surveillance videos over there, so I checked the surveillance videos later, but I found that there were no videos there, and the cameras were all unused. Those The video heads are basically new, that is, they have not been turned on since they were installed, and their memory disks are also broken, so even if they are turned on, they cannot record anything at all.”

Zhang Xuan wanted to continue talking, but at this moment a phone rang in the room. The phone was from Li Yancheng. He took the phone and saw that it was Aman.

But he wouldn't call for no reason and say that the establishment of UnionPay would reach out to Zhang Xuan to continue talking, and then he connected the phone.

Aman on the other end of the phone seemed a little excited. He asked Li Yancheng to go to the scene of the last victim immediately, saying that he had found something.
