Zhang Tianyi sat on a chair in the monitoring room, the computer screen was playing back last night's surveillance video, and when he saw Ye Zi's figure appear in the surveillance, the cigarette between his fingers fell to the ground with a "snap".

Zhang Tianyi pretended to be casual and lit a cigarette, turned his head and asked Lin Fan, "What do you think?" ”

Lin Fan shook his head and said, "I'm not sure yet, this only proves that he appeared in this corridor last night." And as you can see, the police station is so big, and no matter where you go, you will pass by this corridor. ”

"I hope so......" Zhang Tianyi smoked a cigarette and had a lot of thoughts in his heart.

After going to Wang Fugui's rental house last night, Zhang Tianyi found that the voice-activated light at the door had been replaced with a toilet, and there was no doubt that someone had been to the place of the crime after the crime. Later, Zhang Tianyi found a set of fingerprints on the voice-activated lamp, but he didn't collect and compare them, and he didn't know who left them. And the reason why it is suspected that there are ghosts in the police station is because only his own people can unknowingly take out Wang Fugui's mobile phone from the Physical Evidence Department and return it.

Of course, this is possible as long as the people in the police station can do this, but if you want to destroy the evidence in every case, it is not possible for ordinary people to do it. No matter how calm a murderer is when committing the crime, he will always leave clues, but from the beginning of the first case to the present, the murderer of Dakui has not left any strong evidence, which is also only the technical team can deal with the suspicions at the crime scene without leaving a trace, and the technical group is responsible for collecting fingerprints and comparing DNA, including a series of test results.

From the time Wang Fugui was discovered, Zhang Tianyi knew that there must be more than one murderer, and both the modus operandi and the victim group proved that the murderer was committed by a gang, at least two or more. Moreover, the murderer also has professional criminal investigation capabilities, especially in the anti-investigation, which is comparable to a professional police officer, and combined with the previous reasoning, Ye Zi's suspicion is more confirmed.

Zhang Tianyi is going to investigate the case to the end no matter what, on the one hand, to give Senzi Dakui and them an explanation, and on the other hand, it can be regarded as clearing Ye Zi's suspicion, he doesn't want to see that it is his brother who gets along with the murderer day and night.

At this moment, there was a knock on the door outside, and Lin Fan walked over and opened the door to find that it was a leaf.

Ye Zi's eyes were slightly red, and he looked tired, as if Da Kui's death had hit him hard.

"Is the lab report out?" Zhang Tianyi pretended to be casual and glanced at Ye Zi a few times, but he didn't see any traces of strong concealment on Ye Zi's face.

"I tested the physical evidence from the scene brought back by the second team, in which chemical elements such as lysergic acid diethylamide were found in the candles. ”

"Hallucinogens?" Lin Fan asked.

"That's right." Ye Zi nodded and continued: "Lysergic acid diethylamide is a neurological drug, usually added to hallucinogens, and common drugs on the market also contain this ingredient, which can cause people to hallucinate after burning, and even cause ataxia and hyperreflexia in severe cases, resulting in death. ”

"Sure enough, the victim didn't fall ......to death by accident," Zhang Tianyi said to himself, and then turned his head and asked: "This drug should be difficult to buy on the market, right?" ”

Lin Fan replied: "That's true, the control of this kind of neurological drugs in China is very strict, and at present, except for some large hospitals or chemical laboratories, it is difficult for ordinary people to access other channels. ”

"Not necessarily." Ye Zi continued: "The ingredients on the white candle are very few, and the purity is not very high, it is very likely that the murderer extracted it from drugs. ”

Zhang Tian didn't say anything at all, he looked at the slowly setting sun outside the window and lit a cigarette......

After Ye left, the technical team also came to the news that the fingerprints on the voice-activated lights in the bathroom were not Ye's, and they compared the fingerprint library and did not match the same fingerprints.

After getting the appraisal results, Zhang Tianyi's tense heart suddenly relaxed, but then he thought about who it would be if it wasn't Yezi?

Zhang Tian suddenly thought of Yang Yong, but after talking to the surveillance personnel in Sanli Coffin Town on the phone, he learned that Yang Yong had been staying at home honestly during this time and had no unusual behavior.

Zhang Tianyi now feels an invisible sense of urgency driving him, the murderer is no longer satisfied with ordinary crimes, the modus operandi is becoming more and more cruel, and even the target of the crime has been changed from ordinary people to police, if it is not stopped in time, I am afraid that more people will encounter accidents.

After making up his mind, Zhang Tianyi talked to Lin Fan about tonight's actions, Da Kui prepared all the things he needed before his death and put them in the utility room on the second floor, and he could enter the mountain as long as he waited for the blood moon to appear tonight.

"That's right." Lin Fan looked at Zhang Tianyi: "Do you want to call the Shangwu reporter to come with us?" ”

Zhang Tianyi understood what Lin Fan meant, Wu Shengnan seems to be very mysterious at present, whether it is going to the earth gate or the murderer, she knows very well the bizarre modus operandi, although it will be a lot easier for her to join this operation, but Zhang Tianyi does not fully trust her now.

Sometimes it's not a good thing to be too mysterious, and an ordinary murder case eventually involves one strange murder after another, and one seemingly unrelated person after another gradually surfaces. As for Wu Shengnan, she obviously knows a lot, but she doesn't hide it, but reveals the secret to you little by little, everything seems to be in her expectation, and she has always been a calm and breezy appearance, which is somewhat similar to Yang Yong.

Thinking of this, Zhang Tianyi raised his head and said to Lin Fan: "Don't let Wu Shengnan know about this matter for the time being, just the two of us will act this time." ”

Lin Fan nodded in response, but was stopped by Zhang Tianyi and said, "Call the leaves too." ”

Lin Fan didn't understand Zhang Tianyi's intentions, but he didn't ask much, and after finishing speaking, he went out to prepare for tonight's action.

Zhang Tian looked at the slowly setting sun outside the window a little bit of a cigarette and was a little absent-minded, he had a hunch in his heart, tonight's rescue plan may not be so simple.

Zhang Tianyi can't say whether there is an internal ghost inside the police station, but what he can be sure of is that even if there is that person, it will not be Yezi.

First, the fingerprints on the voice-activated lamp have cleared Ye Zi's suspicion, and secondly, whenever he commits a crime, there must be a motive for committing a crime, Zhang Tianyi really can't think of any grievances between Ye Zi and Senzi Dakui.

Ye Zi and Da Kui Senzi graduated from the same school, and at that time, including Keren, they were assigned to Ping'an Town, and Zhang Tianyi and Lin Fan also graduated in the same year and came to Ping'an Town. Lin Fan served as the town's forensic doctor, Zhang Tianyi Senzi was responsible for handling the case in the criminal investigation team, and Ye Zi was assigned to the internal technical team to assist in the criminal investigation and solve the case. After several years of contact and cooperation, they have become a very tacit team, and it is impossible for Ye Zi to kill them, and besides, there is no reason for them to rise to the point of killing each other.

Through the analysis of the previous case, Zhang Tianyi found that the birthdays of all the deceased were March 3, which did not change until Moriko and Da Kui were killed later, and it was also after Moriko's accident that the case seemed to have risen to another level.

From the selective crime at the beginning to the murder in the end, Zhang Tianyi didn't believe it if he didn't have anything to do.

On the other hand, Zhang Tianyi felt that the previous case and the subsequent murder of Senzi Dakui did not seem to be committed by the same person, according to the initial assumption that the murderer was committed by a gang, and the victim group was set to target the people from Sanli Coffin Town on March 3rd, and then the case changed since Senzi, the only thing that is the same is that this time the murderer targeted the police, and looking at the death of Senzi and Dakui, the murderer seems to be maliciously retaliating, killing or torturing the deceased through cruel means to vent his anger, Or as Lin Fan said, the murderer enjoys the feeling of dominating people's lives.

Zhang Tianyi thought of Wu Shengnan at this time, if she was there, she would definitely know what the birthday of March 3 represents. Speaking of Wu Shengnan, Zhang Tianyi is still suspicious of her origin, Senzi's death is nothing more than a high-profile crime committed by a perverted killer in the eyes of ordinary people, but in her opinion, it is a premeditated occult game, the murderer uses the law of the five elements to complement each other and a series of incredible operations to take the soul and practice evil arts.

There is also the coffin nail in Moriko's throat, which he seems to have seen somewhere......

Zhang Tianyi suddenly patted his head, and only then did he remember that Da Kui had more than twenty identical coffin nails nailed to his body when he died.

Da Kui was killed at the entrance of Sanli Coffin Town, and Sanli Coffin Town makes a living by making and selling coffins, and there will definitely be no shortage of coffin nails!

Zhang Tianyi was a little annoyed that he had just remembered it, so he immediately called the police stationed in Sanli Coffin Town, asking them to thoroughly investigate the origin of the coffin nails on Senzi and Da Kui, and by the way, he also told them to be optimistic about Yang Yong, in Zhang Tianyi's heart, Yang Yong is still the first suspect.

Zhang Tianyi lit a cigarette after arranging, and he squinted his eyes and thought a little fascinated.

Moriko was shot, and the gun that shot him was the lost gun he lost in the White Fox's Den, and there was no way to look back in that situation at that time, which means that after he escaped, someone entered the White Fox's Den and took out the gun and shot Moriko. Zhang Tianyi is very clear about the situation in the white fox den, it is impossible for ordinary people to come out alive after entering it by mistake, not to mention that there is a white fox king with the physique of a Bengal white tiger, it is estimated that even Yang Yong may not be able to please it in his hands.

But apart from Yang Yong, Zhang Tianyi really couldn't think of anyone else who had such a great ability to come out of the white fox's den intact. Take yourself as an example, if you hadn't found the exit by mistake, I'm afraid it would have become the winter food reserved by the white fox, although it came out alive in the end, but it was injured, not to mention that he lost his gun, and more importantly, he has been unconscious since he came back from the white fox's den.

Yang Yong...... White Fox King...... Unfinished sacrificial ......" Zhang Tian repeated these key words in his mouth, his eyes were a little dull, and the half cigarette in his hand burned unhurriedly......
