The next afternoon, the special dispatch team was still in the temporary office.

Zhao Yu did not go to the prison directly, but was careful and investigated the prison situation secretly.

He asked Zeng Ke to screen all the staff in Nong Zhifa Prison to try to find out the potential suspects.

The screening criteria given by Zhao Yu is that, first of all, the suspect's age must be at least before 1975. Because the first case of the murder memoir occurred in 1993, the suspect's age must be quite large;

Secondly, this person needs to have enough time to contact Nong Zhifa. If someone really gives Nong Zhifa psychological hints, then the contact between the two parties will definitely be very long;

Finally, and the most critical point is that the suspect's life trajectory must at least be consistent with or close to all the crimes in the murder memoirs.

As a result, after filtering through the above three criteria, the final result is "0"!

There wasn't a single one!

"Team leader..." At this time, Ran Tao gave Zhao Yu an idea and said, "Are we counting senior leaders like the warden?"

"No," Zhao Yu said casually in confusion, "I understand prisons. The prisoners and prison senior officials have almost no chance to meet..."

"What?" Ran Tao was surprised, "Do you know prison? Have you ever been to prison? Hahaha..."

Zhao Yu rolled his eyes and said in his heart that I not only had to be in prison in my previous life, but also had to be executed!

"But..." Zhao Yu thought for a while and said, "This possibility cannot be completely ruled out, so..." He turned to Zeng Ke and ordered, "Please pay attention to the prison's senior management too!

"And..." Zhao Yu said again, "Check the past records and check all the staff who have been transferred from their positions there, including the canteen master, no one can let go!"

"Yes!" Zeng Ke received the order and immediately devoted himself to work.

"Oh, boss..." At this time, Cui Lizhu walked in from outside and said to Zhao Yu, "There is another problem with Liu Cheng. This guy is annoyed by the question and doesn't say anything!"

"No way? What are you doing!" Zhao Yu frowned, "Didn't you say it? You can't ask too much. At least you have to let him go to the garden to talk to Shi Tou every day. These experts are really..."

"No wonder..." Cui Lizhu said, "There are too many suspects. There are hundreds of prisoners alone. It's annoying to see normal people!"

"No way?" Zhao Yu said, "Wang Can is not so stupid, right? At least you have to screen the suspect first and then show it to him!

"Pick out those who meet the conditions first, and you can't push them all to him!"

"Yes!" Cui Lizhu scratched her head, "I'll ask Wang Can, this idiot, he won't treat Liu Cheng as a normal person, right?"

After saying that, Cui Lizhu quickly called.

"Team leader..." As if discussing, as soon as Cui Lizhu left, Wu Xiumin entered through the door and said to Zhao Yu, "I have asked many psychological experts for advice!

"Psychological hints should not be fabricated by film and television, but they are indeed true. Moreover, in the field of psychology, this is already a relatively mature technical means!"

"Oh?" Zhao Yu's eyes widened, "Is this really such a thing?"

"Yes," said Wu Xiumin, "However, psychological suggestion is mainly used in treatment, using emotional interaction principles and various behavioral suggestion methods to provide psychological counseling for patients who have been traumatized, so that they can restore their optimistic and positive attitude.

"Of course, on the contrary, it can also bring pessimism to acceptance... Well..." Next, Wu Xiumin said a lot of professional terms and then said, "Especially for a person with psychological defects, implementing psychological hints will be easier to succeed!"

"..." Zhao Yu nodded, but his expression had betrayed him, obviously he had only a little understanding of it.

"To give the simplest example," said Wu Xiumin, "we ask students to recite a poem. If you tell him that this is a poem written by a famous poet, then his impression will be deeper and he will remember it more quickly.

"But if you tell students that this poem was written by you, it will be a little difficult for students to recite it!"

"This..." Zhao Yu swallowed and asked himself, "Can I write poetry?"

"But, just by suggesting, one person admits that he has killed someone..." Ran Tao raised an objection, "Is this a bit too much?

"If it can be done, wouldn't you want others to do anything? Do you carry a puppet?"

"Yes!" Wu Xiumin nodded, "You are right. It's really not that easy to admit that you are a serial killer and murderer, it's really not that easy!

"I have consulted relevant experts," Wu Xiumin said with a serious expression, "What they said was the same as I expected. If you only rely on ordinary psychological hints, you will definitely not be able to do it. In addition to having certain innate conditions, you also need more advanced means!"

"Advanced means?" Ran Tao raised his eyebrows, "What means?"

Wu Xiumin sank for a moment and said two words "hypnosis" heavily!!

As soon as these words came out, Zhao Yu and Ran Tao widened their eyes at the same time.

"What? Hypnosis?" Ran Tao asked in surprise, "What do you mean... Nong Zhifa may have been hypnotized?"

"Yes, if the team leader's speculation is correct, then only this possibility can be achieved!" Wu Xiumin said, "Hypnosis is also an important method or technique for psychological suggestion. It can make a person's consciousness enter a relatively weakened state, expose the subconscious mind, and then instill some new consciousness in him through repeated prompts. In this way, the hypnotized person will mistakenly think that those behaviors are what he does!"

Bang!

Zhao Yu suddenly snapped his fingers and said excitedly: "I said why do I look familiar! In the video of Nong Zhifa confessing, his eyes looked like that, looking fluttering...

"When I think about it now, it's really like I'm hypnotized!"

"This..." Ran Tao still felt incredible, "Hypnosis, is it really so evil? So... who hypnotized him? Or was it the prison guard in the prison? But we... didn't seem to have found anyone with suspicion?"

"Team leader," Wu Xiumin reminded, "If our assumption is true, then this person who can perform hypnosis must be a master! Perhaps... it should not be difficult to find out!"

"We..." Zhao Yu pondered for a while, then slowly walked to the whiteboard with the case, and said, "The first thing we need to do now is to focus on the situation before Nong Zhifa was imprisoned..."

"Before going to prison?" Ran Tao obviously couldn't keep up with Zhao Yu's jumping rhythm.

"Yes!" Zhao Yu said with a firm look on his face, "We need to know whether Nong Zhifa was in this state before he was imprisoned? If so, then we must focus on him before he was imprisoned!
