Dr. Liu said that he had studied many historical Gu arts and divination methods, and Fu Ping was one of them. Ancient people, in their hearts were convinced of the words of ghosts and gods, so their own psychological hints to themselves were much stronger than those of today's people, so Fu Ping would be passed on so much, and it has been passed down to this day, and has evolved into a psychic method for inviting ghosts such as pen fairies and dish fairies.

Of course, Dr. Lau does not rule out the factor that some people are pretending to be ghosts. After answering our questions, Dr. Liu was leaving, saying that he didn't have many years to live, but he still had a lot of questions to study. He asked the leader not to send him, and walked towards the door by himself, I remembered something important, asked everyone to wait for me, and immediately chased him out.

I stopped Dr. Liu, he turned his head, his cloudy eyes stared at me behind his aged glasses, he smiled kindly, and asked me what was wrong. I have communicated with Dr. Liu many times, and I have not studied psychology, especially psychiatry, but I have been exposed to them all, all thanks to Dr. Liu.

"Dr. Liu, if it is hypnosis, is it possible to make people fall into a state of deep sleep?" I asked.

Dr. Liu nodded, and he continued to walk forward, telling me that in mainland China, mental hypnosis has not yet fully attracted the attention of the academic community, and even many ordinary people do not understand this concept. However, in the non-mainland areas of China, especially in the southernmost part of the motherland, mental hypnosis has long been a research topic in the academic community, and it has been slowly used in the profession of psychologists.

Theoretically, hypnosis is a psychological suggestion behavior, the practitioner through the psychological suggestion of language, sound, movement, and eyes in the recipient's subconscious input information, change their thinking mode and behavior pattern, the recipient can close their eyes, or do not close their eyes, and even unconsciously accept the hypnotist's psychological suggestion.

Dr. Liu said that he started studying hypnosis as early as 10 years ago, but until now, he has only studied the tip of the iceberg. Dr. Liu admits that he can use hypnosis to put people into a state of deep sleep or change people's subconscious thoughts in a short period of time.

"What if you put several people into a deep sleep at the same time?" I asked again.

There is a purpose in asking these questions, I want to know if the criminal policemen who fell asleep in the case of the woman in red and the Qiu Xinghua case were hypnotized, and through the examination, the criminal policemen did not find any chemical components in their bodies that could make people unconscious, and they woke up almost at the same time.

The news of Dr. Liu's research on hypnosis is nothing new in the police academy, everyone has heard of it, and I have read some academic papers and journals on mental hypnosis, and I know the difficulty of hypnosis, so I don't think those people are hypnotized.

Dr. Liu frowned, and he shook his head, thinking it was unlikely. Everyone's psychology is complex, and hypnotism is not effective for everyone, even in developed countries abroad, psychologists who are good at hypnosis need to use different hypnotic methods according to the psychological conditions of different individuals.

"Li Ke, in the same environment, it is almost impossible for the same hypnotist to make multiple people enter the hypnotic state. Multi-person hypnosis, both now and for a long time to come, is a difficult problem in both academic and practical circles. Dr. Liu patted me on the shoulder, and before I knew it, we had walked to Dr. Liu's laboratory.

Before Dr. Liu entered the laboratory, he said to me, he said that hypnosis, if used well, can solve people's mental troubles, but if abused, the consequences are unimaginable. Many people have come to him to ask him about the methods of mental hypnosis, but he is tight-lipped and does not disclose it, he is afraid that some people will use hypnosis to harm others.

At the Police Academy, Dr. Liu was also very careful, even if leaders or officials came to ask for advice, he did not hand over his research results to others. Dr. Liu has not published any papers on mental hypnosis in China, and all his research results are only recorded in his head, and no paper literature has been left.

Dr. Lau was reassuring to me and said that if he had the opportunity, he could come back to this area.

After speaking, Dr. Liu closed the door of the research room, and I stood outside the research room for a while, and then strode back to the task force office. Everyone was discussing, and as soon as I arrived, Wen Ning told me about his next plans. Dr. Liu's statement is authoritative, and he naturally believes it, but Dr. Liu did not rule out that the pen movement was because the two girls had subjective malice, so in order to be sure, he would still investigate the two girls.

On the other hand, as we have previously decided, the case will start from two sides. One is to assume that the fourth girl is the murderer and commits suicide after the murder, and the other is to assume that the murderer is someone else.

The traces of the scene all point to the fourth girl as the murderer, and the father of the fourth girl said that the girl had called home, said that she had quarreled with the other three people in the dormitory, and said that she did not want to live, if there was no way to find other clues, the nature of the case would probably be characterized as such.

But Wen Ning wants to solve all the suspicions clearly, so while he collects clues about the first hypothesis, he will spend more police resources on the second hypothesis. By the time I returned, he had already sent someone to investigate the source of the books. He sent a lot of people out, mainly in the vicinity of the police academy, and went out to investigate all the regular and informal bookstores and roadside stalls to see if they could find the same book or similar books.

In addition, Wen Ning has begun to secretly investigate the two frightened girls, including questioning a small number of classmates who left school together, and also calling back to the homes of the two girls to ask if there is an alibi. I have to say that Wen Ning is very wise, in order not to make people panic, he did not investigate the two girls on a large scale and publicly.

The leader of the police academy said that the mood of the two girls had slowly recovered, and he was ready to disseminate my and Dr. Liu's analysis in the form of lectures, so as to reduce the panic in the school, especially among the female students.

The criminal police who Wen Ning stayed in the back mountain to investigate also came back one after another, and no more valuable traces and clues were extracted from the scene. The criminal police also found the owner of the grave where the corpse mud was extracted, and with the permission of the owner's family, the criminal police dug up the entire body buried in the soil.

Wen Ning wanted to find clues in the tomb, but his calculation did not start. The tomb was only dug with a small pit to expose one of the heads of the corpse, and I don't think any clues could be found in the tomb.

The relatives of the victim did not come to make trouble again, and the parents of the fourth girl were arranged by the leaders of the police academy to live in a hotel near the police academy.

After dark, I went back to the unit, had dinner, and we went to bed early. The next day, I received a call from Meng Ting, who invited us to her home. Several of us were very worried about Meng Ting's mental condition, Wen Ning hadn't brought me good news yet, so I agreed without much thought.

According to the address given to us by Meng Ting, we took our mother to You Lu's house in a taxi. The house is very large, it is a very spacious villa, and when Jiang Jun saw the villa, he was surprised at how much money You Lu made by painting. Meng Ting was waiting for us at the door, and compared with the previous few days, Meng Ting's complexion was much better.

She welcomed us into the house, Meng Ting took the initiative to hold the hands of Xu Yi and her mother, I paid attention to Meng Ting's palm, on the day of the wedding, Meng Ting removed the gauze, and now look at it, the wound has recovered very well. Meng Ting said that You Lv was painting at home and forgot the time, so he didn't come out to pick us up.

You Lu didn't live with his parents, and only Meng Ting and him lived in the huge house. Meng Ting said that before getting married, You Lu lived alone in such a big house, and You Lu said that when he painted, he didn't like to be disturbed. Meng Ting took us to the living room to sit down, and Xu Yi asked her why she didn't go on a post-marital trip with You Lu.

Meng Ting smiled and said that You Lu was uncomfortable not painting for a day, and she didn't want to walk around, so she didn't go. Meng Ting got up to make tea for us, and we looked around.

The painting that You Lu painted for Meng Ting was hanging on the wall of the living room, and Meng Ting on the wall was lifelike, staring at us and smiling......
