The whiteboard in the criminal police office rarely contained some information labeled as the murderer. With Qin Chuan as the center, a new relationship diagram appeared, while the information about the deceased Li Manyu was moved to a corner.

"Qin Chuan's father had a history of heart disease. Both Qin Chuan and Jiang Linli were present on the day of his death. Later, Qin Chuan followed his mother Jiang Linli to the Tea Country. Based on the interviews, two things should be confirmed."

Lei Zhen said: "First, Jiang Linli has a bad reputation and often hangs out with men. Second, after Qin Guisheng's death, Qin Chuan was in a trance, irritable, and fought with neighbors every day. Compared with before, he was completely different.

He has become a different person, and I suspect that he has been stimulated and suffers from a serious mental illness."

Xia Lan nodded slowly, "Jiang Linli has no job, and her ex-husband Qin Guisheng's income is not high. She does not have the financial ability to take Qin Chuan to live in the Tea Country. The person who provides her with funds is most likely her lover."

The police in the tea capital of the country have assisted them in investigating Jiang Linli's situation. The answer they gave was that Jiang Linli was not at home and there was no abnormal sign at home.

Because there is no surveillance in the town where Jiang Linli lives, the tea country police cannot give any more information.

Qin Chuan is a forensic doctor. With his professional ability, it is easy to eliminate traces at the scene. If he disappeared at this time, they can only think that Jiang Linli has been killed.

Lei Zhen's fingers tapped rhythmically on the table, "Based on the previous profile, I feel like this. Jiang Linli took Qin Chuan to live abroad and received psychological treatment at the same time. The effect should be very good. In order to prevent Qin Chuan from

After being stimulated again, Jiang Linli has been hiding the existence of his lover."

"One day a month ago, Qin Chuan found traces of his lover, probably his dander and hair at home. Qin Chuan was stimulated again, strangled Jiang Linli to death, and returned to Mengshan following clues

, I want to find that man to avenge my father."

Xia Lan's expression was a little complicated, "The tea country gave me some information about Qin Chuan. He is usually a sunny and warm man with a very good temper. He is completely different from the Qin Chuan we saw today. I feel that he may have a dual personality.

"

Dual personality.

We have all seen this word on TV or in books many times, but when we encounter it, we don’t know how to determine it. Fortunately, the police force already has a tacit understanding. When you are hesitant, ask Sun

Just feathers.

Everyone's eyes unanimously focused on Sun Yu.

Sun Yu never disappoints everyone. He said: "Dual personality is a serious psychological disorder. Simply put, a person has two relatively independent and separate personalities at the same time."

"According to Qin Chuan's experience, his dual personality should be a means of self-defense and self-protection. When he was 16 years old, he saw his father die with his own eyes. That day was the 47th day after Qin Guisheng divorced Jiang Linli. The only reasonable

The explanation is that Qin Guisheng suffered a heart attack due to strong stimulation that day."

"As a witness, Qin Chuan knew that his biological mother had killed his father and suffered an excessive blow, so he chose to isolate himself and escape from the incident by deriving a second personality. The second personality generally has a strong desire to protect the first personality.

, he will argue with the people around him over trivial matters to protect the body of the first personality."

After listening to Sun Yu's explanation, everyone had guessed what happened that day. Qin Chuan discovered the existence of his lover and fell into self-isolation again. The second personality appeared, which caused the tragedy that followed.

"Are there any intersections between the memories of the first personality and the second personality?" Xia Lan asked. She knew that Sun Yu was also a great psychiatrist.

Sun Yu shrugged, "It's hard to say. According to the data over the years, very few memories have no overlap, but there are two types of memories that have overlap. One kind can remember clearly what happened, and most of the time the other

There are only some vague fragments, just like a dream."

"Is there any way to awaken Qin Chuan's first personality?"

"Two methods. The first is to cooperate with a psychiatrist for treatment. You have also seen Qin Chuan. He will definitely not accept treatment. The second..." Sun Yu paused, "Hypnosis! Forcibly give up.

The second personality fell into a deep sleep."

"Then you..." Xia Lan didn't say any more. She didn't know if everyone knew that Sun Yu was also a psychiatrist. She believed that Sun Yu could understand what he meant.

Sun Yu shook his head, "General psychiatrists will use sleep hypnosis, which requires the patient to trust the doctor before proceeding. Qin Chuan's situation requires conscious hypnosis. As far as I know, there are only two people in China who can do this.

Professor Gong Yongsen from Kyoto.”

"As for Professor Gong, I have participated in one of his exchange meetings, and I do have his contact information." Lei Zhen said as he took out his cell phone, preparing to look for Gong Yongsen's phone number.

"I do not agree with using hypnosis to deal with Qin Chuan." Sun Yu said solemnly, "Hypnosis does not have any legal effect in the country. It can even be said to be an inhumane behavior. Also, you

Don’t you think it’s embarrassing to use hypnosis to solve crimes?”

The office suddenly became quiet. Sun Yu's first sentence was about truth, and they didn't pay much attention to it, but the second half was about face, or dignity.

Facing a case with no solution, searching for clues through hypnosis is not what a criminal police officer should have.

"Indeed!" Xia Lan broke the silence, "Qin Chuan is so arrogant, he will definitely continue to commit crimes and provoke the police again. The second personality was so impulsive when he was 16, and now he can only become more aggressive. How can he restrain himself?"

Bao Youliang, who has always been silent, echoed: "I also feel that although he was provoking us today, he acted too calmly. This made me feel that he was deliberately suppressing himself and needed to be released, so he would commit a crime soon."

.”

After that, Xia Lan arranged a task of two people working in groups to monitor Qin Chuan 24 hours a day. Although this might force Qin Chuan to suspend the crime, everyone knew that there was nothing worse than another death.

Another task is to find Jiang Linli's lover. This man has a high income and was a rich man eight years ago. He may have traveled back and forth between the tea country and China in these years.

These labels are relatively obvious, and based on the police's ability, they can roughly find out in a few days.

On the first day of monitoring Qin Chuan, Zhang Yao and Xu Hui, who were following him, sent back an irritating message.

After Qin Chuan arrived at the parking lot of a shopping mall, he got out of the car, came to look for them, and took photos of them. In the afternoon, Qin Chuan took photos of Fu Ming and Bao Youliang who were following him.

At that time, Qin Chuan even mocked Fu Ming, "Is this the level of domestic police tracking?"

This is a provocation, and it also tells the police that Qin Chuan has strong counter-reconnaissance capabilities.

At the end of the day, Qin Chuan visited many places, including supermarket shopping, bookstores, fast food restaurants, gyms, restaurants, and night fishing in Mengshan.

I have to say that Qin Chuan's appearance is indeed that of a young woman killer. According to the statistics of the trackers, there are 13 women who have talked to Qin Chuan, 8 of whom are over 35 years old.

"I prefer the gym, because Qin Chuan's muscles can be fully displayed there, which makes it easy to attract women." This is Fu Ming's opinion.

"I think it's a bookstore, because Qin Chuan's talent can be fully displayed there, and it's easy to attract women." This is Zhang Yao's opinion.

Xu Hui secretly asked several women who had spoken to Qin Chuan. They all had a good impression of Qin Chuan, and their words revealed their love for him.

It was still the same the next day. The first few places were exactly the same, but Qin Chuan changed his route when he came out of the gym in the afternoon. He drove to the Public Security Bureau and entered the reception room.

Xia Lan immediately had an ominous premonition, and sure enough, twenty minutes later she received a call from Zhao Changsheng, asking her to go to the director's office immediately.

When she entered Zhao Changsheng's office and saw the anger on his face, Xia Lan knew that she might have been plotted by Qin Chuan.

"First, let's talk about the relationship between the floating corpse case and Qin Chuan."

Xia Lan immediately told everything related to Qin Chuan. When he heard that Qin Chuan deliberately provoked Xia Lan, Zhao Changsheng showed a ruthless look on his face, but it was quickly replaced by helplessness.

"That Qin Chuan came to the bureau to complain about you, saying that you admired his appearance and asked to date him. After he refused, you arranged for people to follow him through work and put pressure on the people around him."

Xia Lan almost imitated Sun Yu and shouted "Fuck". She was so angry that she laughed, "Do you believe this?"

Zhao Changsheng looked at Xia Lan as if he were facing a formidable enemy. Xia Lan immediately stood at attention and said, "This person should have strong anti-reconnaissance capabilities, right?"

Seeing Xia Lan nod, Zhao Changsheng continued: "He took photos of all the people who followed him, and compared them with the women today. They recognized the person who asked them yesterday in the photos. This is evidence! Just rely on it.

Now, if he puts this matter online, where do you think the public opinion will be?"

Xia Lan was so angry that she clenched her fists and said coldly: "Then what should I do? Remove the people who are monitoring him and let him continue to commit crimes?"

"You haven't experienced the horror of public opinion. Listen to me and remove it publicly. I will arrange for you to have a group of people to monitor you from a distance."

Xia Lan opened his mouth, not knowing what to say. With Zhao Changsheng's rich experience, he also knew that once it was changed to long-distance surveillance, it would be equivalent to no surveillance for someone with strong anti-reconnaissance capabilities like Qin Chuan.

"Director Zhao, he provoked us like this and we still gave in, I..."

Zhao Changsheng interrupted Xia Lan, "Obey the order! Get out!"

Xia Lan knew that Zhao Changsheng had his considerations, but at this moment she really couldn't accept the order. After leaving the director's office, Xia Lan called Sun Yu and told him Zhao Changsheng's arrangement.

"Director Zhao is an old fox, and what he said is right. Have you ever thought about what the police will do once he posts this matter online?"

As soon as Sun Yu reminded her, Xia Lan suddenly woke up.

Once Qin Chuan makes trouble, the police can only respond truthfully, suspecting that he is related to the floating corpse case. Qin Chuan will definitely take the opportunity to ask the police to announce the progress of the case, and the DNA matter will have to be exposed.

At that time, they will have to determine the owner of the DNA.

This man is so scheming!

After thanking Sun Yu for the reminder, Xia Lan chatted for a while, "The case hasn't been solved yet, where have you been these two days?"

Sun Yu's answer comforted Xia Lan's bad mood.

"Wait for the wind to come!"
