"We have a little understanding of this. What we want to know is that the sick people can really switch personality seamlessly? To be honest, when I see this disease, I think it's very unreal because it's too unreal."

Qin Zhan expressed his true feelings without any hesitation. When he first saw this, and the videos that You Hemei asked him to watch, he felt very unrestrained, as if he was acting alone.

Yang Jun did not show any dissatisfaction with this, but instead gave an understanding look.

"It's not just you, I believe that most people think so, because they have never seen such things, and have never heard of them. Humans always have a skeptical attitude towards things that they have never understood. There is no doubt about this."

Qin Zhan fell silent after hearing this. He had to admit that what Professor Yang said in front of him was true.

"This disease is real. Even if the chance of it is small, people who will have this mental illness must be inseparable from childhood or past experiences. Some news from current research is that it has a great relationship with the abuse in childhood. Only when they suffer great despair or even pain, in order to escape, another personality will appear."

When he heard this, Qin Zhan and You Hemei looked at each other, and could see the shock in their eyes and the lack of knowing how to speak.

"The personality produced at this time is to protect the master's personality, inherit painful memories, and make the master's personality completely unaware that such a thing has happened. Once the first personality appears, other personalities will gradually be derived. This is what we call multiple personality, and personality also grows slowly, not that several personalities appear at once."

You Hemei and Qin Zhan can be said to have a clearer understanding of Yang Jun’s explanation.

"Professor Yang, I'll ask you presumptuously. According to what you said just now, does it mean that each personality appears because of what the master has experienced? The personality produced during this period is also for the purpose of protecting the master's personality? Is it possible that this personality that appears may also become worse?"

You Hemei hesitated for a moment and asked out the questions in her heart.

Yang Jun first glanced at the person, then slowly said: "Although this is not clearly proven in medicine, I think this is not impossible. You should know that each personality has its own world view, values, and personal view. In addition to the common container of this body, it can be said to be another person who is completely independent."

If you say this, You Hemi probably had some answers in her heart and nodded to others.

"Thank you Professor Yang for answering the questions."

"You are welcome, is the reason you came to me to understand the doubts?" Yang Jun smiled disapprovingly.

"Professor Yang, thank you this time. I think we have a clear understanding."

Qin Zhan stood up, reached out to the person, and said politely.

Yang Jun also stood up, shook Qin Zhan's hand, and smiled and said, "It's okay, I also heard that you need help in the case. If you think there is any problem in the future, you can come to me at any time."

This sentence proves that Qin Zhan can come to him at any time in the future without making an appointment or something.

"Okay, then we'll go back first." Qin Zhan also grinned and looked at the person with a smile.

After saying goodbye to the people, Qin Zhan and You Hemei left Yang Jun's villa and returned to his car.

"Professor Yang's words can be said to be very clear, but now that the suspect no longer shows up, we will have no chance."

Qin Zhan sighed and said helplessly.

"I just remembered one thing. I saw that woman at the bus stop several times before. When I asked you that time, I saw that woman had gone up to the eighteenth floor. It seems that the other party might have been preparing to start the second crime."

You Hemei also patted her head lightly. Why did she remember such an important thing until now?

In fact, it’s no wonder that she was spent after that incident, and it was normal that she didn’t think about it for a moment.

"I asked Xu Hao to investigate the community where I live and the nearby ones."

Qin Zhan immediately called Xu Hao and gave an order to the person.

Xu Hao was not vague and immediately acted according to the instructions of the people.

"Let's go back too." After Qin Zhan hung up the phone, he started the car and rushed back.

On the way, You Hemei was thinking about something. Professor Yang also said that people who suffer from this disease are all personality that is caused by huge harm in their childhood. So what kind of abuse has been suffered to make a normal person look like this.

Now, it is because of these things that have made irreparable mistakes.

When he thought of his childhood, You Hemi couldn't help but think of what he had experienced, and his body became stiff for a moment.

Qin Zhan seemed to feel the change in the body of the person sitting on the passenger seat. He frowned slightly, reached out and covered You Hemi's hand, and said softly: "Don't think about those unpleasant things."

You Hemi's thoughts were pulled back to reality, and she saw the soft expression on Qin Zhan's face and the other party holding his warm palm. A warm current in her heart passed by, and her body slowly relaxed.

"I'm fine."

Seeing that it seemed that it was really okay for Qin Zhan to take back his hand and drive the car carefully.

"Are we going back to the police station directly?" You Hemei asked again.

"Well, go back to the bureau and wait for Xu Hao's progress."

After hearing this, You Hemei didn't say anything. Anyway, she had nothing to do next, so why not go back to the police station and wait.

After making this decision, the two of them returned to the police station directly.

When he returned to the police station, Qin Zhan was called by the director. It seemed that because the case had a great impact, three people were killed in a row, but the suspect was still not caught. He said what was going on? If he was not capable of doing things, he would be handed over to someone else to do it.

You Hemei went to Qin Zhan's office and waited directly, sitting on the sand quietly waiting for people to come back.

Half a day passed like this. It was almost evening when Qin Zhan's figure appeared at the door of the office, and Xu Hao was also walking with him.
