Zhang Wenzhong, Tan Qingqing, and the captain of the criminal police team went up to the staircase on the fourth floor.

In the process of going upstairs, Zhang Wenzhong had already learned the name of the captain of the criminal police team from Tan Qingqing -- Li Chaoyang. This is a senior criminal police officer with rich experience in criminal investigation and has solved many major and important cases. Even Tan Qingqing was brought out by him, so he had a kind of awe for him from the bottom of his heart.

At this time, in the corridor on the fourth floor, apart from Cai Ni and the girl she had kidnapped, there were only negotiators, psychiatrists, and two special police officers. The other policemen hid at the top of the staircase where Zeni couldn't see, so as not to irritate her, causing irreversible consequences.

When these policemen hiding at the stairs, after seeing Li Chaoyang and Tan Qingqing, they all hurriedly greeted softly: "Team Li, Deputy Team Tan, you guys come up." Hey, didn't you say there's a new negotiator? Why didn't you see anyone? Where is he?"

"That's him. Li Chaoyang stretched out his hand and pointed at Zhang Wenzhong, who was standing beside him.

The policemen couldn't help but be stunned, they never thought that this new negotiator was so young. And at this time, they also saw the identity tag pinned to Zhang Wenzhong's white coat.

"Yongcheng University Campus Hospital Zhang Wenzhong...... School doctor?"

"Team Li, you're not joking with us, are you? Isn't it said that the person who came here is an expert negotiator? How is it a school doctor?"

"The negotiators and psychiatrists are helpless, how can this school doctor be able to persuade this mentally disturbed suspect at a young age? Team Li, you must be the wrong person, right?"

The policemen were surprised and whispered their opinions. As expected, no one believed that Zhang Wenzhong could persuade Caini.

"Okay, don't talk nonsense, can you do it, let him go up and try it? You just have to be prepared to rescue the hostages, and you don't need to worry about other things. Li Chaoyang snorted and stopped the discussion of the police.

"Yes. The policemen looked grim and answered softly in unison. They are both respectful and afraid of this unsmiling Li Chaoyang.

"It's up to you now, and I hope you won't let us down. Li Chaoyang gestured to Zhang Wenzhong, signaling that he could go and try to persuade Caini.

Zhang Wenzhong smiled and nodded, which was an answer. He didn't rush out of the staircase, but quickly took off his white coat, revealing the shirt he wore inside, and then walked out of the staircase and entered the corridor. At this time, he looked like a young college student. He did this for a reason, to weaken Zeni's vigilance and gain her trust more easily.

Zhang Wenzhong's appearance not only attracted the attention of Caini, but also the attention of negotiators and psychiatrists.

"Who are you, what are you doing here, get out of here!" the negotiator and psychiatrist asked softly.

Zhang Wenzhong's age made them mistakenly think that he was a student of Yongcheng University, and they were all surprised at the moment, wondering why the policemen guarding the staircase let this young man in.

"I'm here to persuade you to take over Zeni, you can go and rest for a while. Zhang Wenzhong replied, and at the same time he also said to the two special policemen: "You two should also go, there are more people staying here, but it is easy to strengthen Caini's vigilance." ”

"You...... Let's all go?" the negotiators and psychiatrists all looked at Zhang Wenzhong with idiot expressions, and they couldn't help but wonder if this person could be a mentally deranged person like Caini?

Li Chaoyang, who was hiding at the top of the stairs, suddenly turned gloomy, turned his head to stare at Tan Qingqing, and snorted softly: "Let the special police also leave?

Tan Qingqing said: "Since we have chosen to believe him, we might as well believe it to the end." Moreover, he is also a practitioner, and his kung fu is still above me, if there is any sudden situation, he should be able to deal with it. Even if he can't handle it, isn't there still you, the sharpshooter? ”

He ...... Is it really as powerful as you say?" Li Chaoyang was a little skeptical about Zhang Wenzhong being a martial arts master, but he knew very well how powerful Tan Qingqing's fist and foot kung fu was.

"Yes, I used to fight him, and I was not as good as him. Tan Qingqing told the truth.

"Well, we'll believe him once. After muttering for a few seconds, Li Chaoyang chose to believe Zhang Wenzhong, and at the same time he also pulled out his police pistol, so that in the event of an accident, he could injure or kill the suspect in time, so as to play a role in rescuing the hostages.

It can be seen from this action that he still doesn't believe Zhang Wenzhong very much. This is also understandable, anyone who doesn't know Zhang Wenzhong probably won't believe him at this time. After all, he was too young and unfamous.

Tan Qingqing picked up the walkie-talkie and said, "Do as he said, you guys will withdraw from the corridor for the time being." ”

Although there were many doubts and dissatisfactions, the negotiator and the two special police officers could only obey the order and temporarily evacuate the corridor. As for the psychiatric expert, although he is a professor at Yongcheng University, he is not under the jurisdiction of the police, and he is only assisting them in handling the matter. But when he saw that the two special police officers had withdrawn, he looked at Cai Ni, who was holding a kitchen knife and covered in blood, and finally looked at Zhang Wenzhong, shook his head involuntarily, and sighed lightly: "It's all *** crazy......" Then he hurriedly followed behind the two special police officers and withdrew from the corridor.

In the corridor on the fourth floor, only Zhang Wenzhong and Cai Ni were left, as well as the girl who was held hostage by Cai Ni and was already stunned.

Suddenly, a smile appeared on Zhang Wenzhong's face.

This smile is very peaceful and soft, and people can't help but feel that Zhang Wenzhong is a very kind and trustworthy person, as if he is the brother or younger brother next door who has played with him since he was a child.

Zhang Wenzhong took this smile and walked slowly towards Caini.

Cai Ni tilted her head, staring at Zhang Wenzhong with a pair of eyes, and gradually, in her eyes, she was a little less vigilant, a little more intimate and confused.

"It's ...... Hypnotism?" The psychiatrist had evacuated the hallway, but he was hiding at the top of the staircase, and he could still see what was going on in the hallway by the angle. Although he couldn't see the smile on Zhang Wenzhong's face, from the change in Caini's expression and the special regularity that Zhang Wenzhong showed in his gestures, he still guessed at once that Zhang Wenzhong was performing hypnotism on Caini.

The psychiatrist guessed correctly, Zhang Wenzhong was indeed performing hypnotism at the moment.

Through the information about Caini obtained from Su Xiaomei and her room director, Zhang Wenzhong keenly judged that if he wanted to convince this slightly introverted and autistic Caini, he had to gain her trust and favor. In a short period of time, the only way to achieve this effect is hypnosis!

The so-called hypnosis is the use of special behavioral techniques, combined with verbal cues, to make people enter a temporary, sleep-like state. In the current situation, hypnosis can reduce Caini's nervousness and irritability, so that she can't help but trust Zhang Wenzhong.

In fact, hypnosis has been used in clinical treatment for a long time. There is even a record of hypnotism in the Neijing. However, at the time, hypnosis was known as Zhuyu, a kind of psychotherapy that did not require acupuncture or drugs, but only relied on verbal and motor cues to achieve therapeutic effects.

Unfortunately, because this kind of psychotherapy is relatively difficult to master, and it is shrouded in a layer of mystery, it gradually evolved into superstitious witchcraft that uses charms to cure diseases.

What Zhang Wenzhong is now performing is the genuine Zhu You technique! That is, the ancient Chinese hypnotic technique!

Gradually, the distance between Zhang Wenzhong and Cai Ni has been shortened to five meters.
