"Captain Wang, come and take a look." Everyone was chatting when a captain from the Shangjing Municipal Bureau came over and called Wang Liang, who immediately followed.

The main business tonight is still arrests. Wang Liang has high enough authority and can see arrest and case materials from all over the country.

Generally speaking, the law enforcement and case handling systems are independent in each city, and each city cannot see the cases of the other city, because each city has its own system designed by its own people. When there are arrests or large transcripts uploaded, the relevant information will be sent via intranet email, and then the police in the Beijing Municipal Bureau will make statistics, and these statistics will be reported to Wang Liang and others in the end.

Wang Liang was called away, and the others continued to talk about the case.

"Wang Liang is a little confused because of his concern," Liu Shuyuan said, "In fact, many of our ways of doing things can be traced. As long as you have dealt with Bai Song, how much you can deduce depends on your IQ."

"I have actually met quite a few people over the years," Bai Song nodded. "Okay, let's not guess anymore. Let's wait to meet Wang Shichun tomorrow. Let's go over and help Wang Liang first to see if the capture is going smoothly in various places. Maybe catching a certain fish can provide some new clues."

"Yeah," Liu Shuyuan nodded.

The list Hou Fangyuan brought back included Mi Mei and some of her partners' people in China, all of whom received money regularly. At present, some places have already arrested people and interrogated them to reveal some information.

These people in China are mainly divided into three levels. There are many people at the lowest level, who are just miscellaneous people. They are responsible for withdrawing cash, setting up company accounts, finding people to help withdraw cash, etc. They are generally suspected of assisting in information network security crimes and fraud, and are the easiest to be arrested. The people arrested this time are all middle-level people. These people are behind the scenes, with a lot of fake identities. They also get their salaries through fake identities, and then go to places to withdraw cash.

Generally speaking, the average monthly income of those arrested this time is more than 50,000 yuan. The middle-level people are also divided into two levels, the heads of large regions and the ordinary heads.

According to the arrested people, there are so-called senior officials, but they have never seen them. They only heard that the senior officials were in direct contact with the other side. The person who mentioned this was a person in charge of a large region. He also only heard that there were senior officials, but he had no idea how many there were or what they were like.

Not only that, but we also got an important piece of information from Shangjing. The person in charge of the big region in Shangjing confessed that they would continue to report some intelligence to the headquarters, and the reporting method was mostly through the dark web.

According to the system in Shangjing, when they distribute money, the regional director will arrange it, but the intelligence they obtain is reported to the headquarters separately, and no one knows each other. I didn't get much valuable information from this regional director, and most of the others may not have seen the situation clearly, so they chose to keep silent.

…

It was noon the next day when Bai Song saw Wang Shichun.

Last night's arrest went very smoothly, directly destroying Mimei's ten-year operation across the country. In addition, the arrest of these people directly led to the collapse of several servers. Several websites were already finished, and a phased victory was achieved. The entire task force was in a state of celebration, but this emotion did not affect Bai Song at all. These were not what he urgently wanted to know.

After Wang Shichun was detained in the detention center, Bai Song and Liu Shuyuan were the first to enter the interrogation room.

Criminal detention has been approved, so only a physical examination is needed to detain the person directly, and then a statement can be taken.

Wang Shichun had never been to such a place before. He looked around and found it somewhat novel.

"Why, you haven't been to this place before?" Bai Song asked.

"No, no," Wang Shichun then realized that the police had arrived.

"It's okay. You'll get familiar with it slowly. It'll take at least several months." Bai Song nodded.

"Hmm..." Wang Shichun didn't understand what "at least several months" meant. He stopped looking and asked Baisong: "Officer, you arrested me, what do you want to ask me..."

"What do you think I want to ask you? Do you have a lot of things to do?" Bai Song saw Wang Shichun was about to speak, so he interrupted him directly: "I can tell you responsibly that there is a reason for arresting you. You are suspected of a murder case. If you plan to confess to us, or have anything to tell us, I hope you will choose your words carefully, don't say too much nonsense, and don't avoid the important issues."

"I... I didn't kill anyone..." Wang Shichun looked around, feeling a little anxious.

"I gave you a chance, but you don't want to use it?" Bai Song wanted to start from the beginning: "You are suspected of conspiracy to commit murder, dismemberment and trafficking of human organs. After I have said so much, you should know which case it is, right?"

Seeing that Wang Shichun was still trying to argue, Bai Song continued, "Do you think that woman will go crazy? No, your psychological suggestion has long been discovered by our experts. She is fine."

"What?" Wang Shichun's eyes widened. He clenched his fists and slammed the table hard: "I said no!"

"So you knew it and are going to run away?" Bai Song asked.

"That guy, he...his words are very convincing. Anyway, I believed everything he said at the time. And everything worked out according to what he said. He was also very rich. I..." Wang Shichun suddenly became a little emotional: "But later, I had dinner with a gangster and talked about selling kidneys. He told me that the maximum amount would be less than 100,000. Later, I asked around and found out that it was true. I knew there was something wrong! Then, the way that woman looked at me! Something was wrong with her eyes, and I ran away!"

"Tell me about this person," Bai Song didn't expect that Wang Shichun didn't need to be interrogated, and he went straight to the point. Although Wang Shichun deliberately avoided the murder, it was almost the same as admitting it.

"He is only in his 20s, with bright eyes. I met him by chance, and I felt that he was very extraordinary. His...his eyes were really charming!" Wang Shichun didn't know if he was making excuses for himself, but he praised this person highly.

"What's his name?" Bai Song asked.

"I don't know his name, I only know his name is Y." Wang Shichun thought for a moment and said, "Well, it's just the English letter Y."

"Y?" Bai Song was stunned for a moment. Was Ren Xu really right? Was there really such a code name?

"Well, I thought it was a little weird at first, too, but that's just what he calls himself."

"How did he find you?" Bai Song asked.

"I don't know either. I was at the construction site that day, and he came to me on his own initiative. The first thing he asked was whether I wanted to make money. I thought he was a liar at the time. In this society, even brothers cheat each other, and they are all afraid that the other party will make more money than themselves. How can there be a good thing to arrange money-making opportunities for others? However, he really brought me an order very quickly, and really made me earn several thousand, and it was very easy. At that time, I was just trying to win over this woman, and he also helped me, and it was very, very smooth." Wang Shichun is still a little scared. He looked around again: "He said a lot to me, but..."

Wang Shichun fell into memories. He...

"Are you from Northeast China?" Bai Song suddenly asked.

"Yes, I'm from Jilin Province." Wang Shichun said.

"That's a bit strange. Why do you always speak Mandarin?" Bai Song said.

"Mandarin?" Wang Shichun was stunned, looking around, "Why am I speaking Mandarin now?"

Bai Song frowned. Was Wang Shichun brainwashed?

According to the current situation, Y influenced the woman who killed her husband through Wang Shichun, but what is strange is that the woman can't remember what Wang Shichun said to her, and Wang Shichun can't remember much of what Y said.

This situation has occurred before. Zuo Xiaoqin has a very poor memory of X's situation and cannot remember any specific details.

Bai Song looked at Liu Shuyuan, and Liu Shuyuan nodded.

Hypnosis.

Is there such a thing here?

Psychological suggestion and hypnosis are actually similar things, and can even exert some strong control over people. The principle of hypnosis is to put people into a trance state, in which the consciousness of the person enters a semi-dormant state, while the subconscious mind is more active and susceptible to psychological suggestion.

In the movie "Hypnotist", people can enter or leave a hypnotic state by snapping their fingers. This behavior not only exists in reality, but some people can also hypnotize animals. At present, some regular hospitals have hypnosis therapy for insomnia, and it is really effective.

"I've learned this before," Bai Song whispered in Liu Shuyuan's ear, "Hypnosis can even make people forget some memories. Some methods, through advance design and careful routines, can even make the hypnotized person show violent tendencies, a stronger sense of defense, or even kill people."

Liu Shuyuan nodded, indicating that he understood. He wanted to see Wang Shichun: "We here have to speak in Northeastern dialect."

"Hey, brother," Wang Shichun suddenly became more energetic. "Why do I feel so happy when you do this?"

"Then tell me quickly, what exactly did you do last time?" Liu Shuyuan asked.

"What's the matter, brother?" Wang Shichun looked at Liu Shuyuan with a confused look on his face.

Bai Song stared at Wang Shichun and nodded secretly.

This Wang Shichun seems to have two different states. It is unlikely that he has a dual personality, but it is more like a dual state.

When Wang Shichun was speaking Northeastern dialect, he was a very normal person. We need to find a police officer who is fluent in Northeastern dialect to ask him about this. In short, during the Northeastern dialect stage, Wang Shichun basically knew nothing about those things.

While Wang Shichun was speaking Mandarin, he knew that he had been in collusion with someone to kill someone, and he also remembered some less important processes. More importantly, he was very afraid of Y and was always worried that he would be killed. Even in the detention center, he kept looking around, fearing that Y would come out of the dark and kill him.

If the police kept speaking Mandarin, they would basically be unable to get anything out of him. But if the police kept asking questions in Northeastern dialect, Wang Shichun would probably gradually recover, but no one could be sure.

Some psychological suggestions have a special button, such as snapping fingers. Once this button is touched, the state of the hypnotized person will change. It is not suitable to try it rashly.

Bai Song and Liu Shuyuan can both speak a few words of Northeastern dialect, but not well enough, so they need an experienced old criminal policeman from Northeast China to come and talk slowly, so that Wang Shichun can completely regain his own personality, and they also need the cooperation of a psychological expert.

"Why did you go to the Magic City?" Bai Song thought of this question: "It's not convenient to go to a big city like the Magic City."

"I run around everywhere. I go wherever there are a lot of people." Wang Shichun looked around again. "I like places with a lot of people."

"Will you feel more at ease with more police officers?" Bai Song asked.

"No, I'm afraid of you." Wang Shichun retorted.

Bai Song nodded, stood up, and asked the guard to send Wang Shichun back to the cell with more than 30 people, and turn on all the lights so that the cell would be as bright as outside.

"We can't let him stay here for long," Bai Song said. "He doesn't feel safe here. Hurry up and find a psychologist. Although I'm good at criminal psychology, I'm not that good at hypnosis and psychological suggestion. Have you noticed that X and Y have their own strengths? X's psychological suggestion and hypnosis skills are average, but the cases he designs are more complicated and rigorous. Although Y can't design such complicated cases and doesn't understand human nature well enough, his hypnosis skills are really professional."

"Why are the opponents you are facing so strong?" Liu Shuyuan said, "I still don't understand what hypnosis is for. Although I can see that Wang Shichun's condition is not normal, I don't know the principle behind it."

"It usually makes people relax or concentrate, which makes them feel dazed. To put it simply, it makes the person being hypnotized have a reduced ability to judge themselves, lose some perception, and be more receptive to the hypnotist's orders. It can even reintegrate a lot of information in the subconscious of the person being hypnotized." Bai Song thought for a while, "A good hypnotist usually has a very high IQ. When talking about hypnosis, there is a modern figure that cannot be avoided."

"Freud?" Liu Shuyuan had a pretty solid foundation in university courses.

"Yes, Freud. When we were in school, we had several courses including criminal psychology that included him. Modern psychology cannot avoid this person. I have read his books The Interpretation of Dreams and Beyond the Pleasure Principle before, but I have basically forgotten them and have not studied them in depth," Bai Song said. "But in fact, these things have been further developed in modern times. Freud's research on human subconsciousness is groundbreaking. I have learned a little bit. For this matter... I think we should invite a professor from our school."

Bai Song knows very well that this is the police's greatest advantage. We have a country to back us up, and individual heroism will not work.
