The prison was still extremely quiet, and there was no other sound except for the breath that would only sound more than a minute.

This claustrophobic environment will undoubtedly cause extremely strong mental torture to people. If anyone who is not so mentally strong here does not take more than one day to feel crazy. If it is not done well in three days, it will be on the verge of collapse.

According to the latest research report of the Milky Way, anyone, even the most mentally strongest warrior, who is forcibly detained in this environment for more than ten days, will suffer the most complete damage to his mental state and it is basically impossible to return to normal in the future.

Chu Nan has been locked up here for seven days.

But from the surface, he had no change compared to when he was locked up on the first day. His expression was still calm, his eyes were not flustered, his clothes were meticulous, his hair was not messy, his whole body was still neat and tidy, even all the facilities in the room were neatly arranged, and the bedding on the bed was very clean and flat, without any mess.

From this perspective, he seems to have not been affected by the detention at all, and his daily life is very stable and regular. In addition to normal eating and excretion, he also chooses a fixed time to bathe every day and spends a certain amount of time to clean himself from head to toe.

Although this prison is claustrophobic, the facilities inside are not bad. Everything has food, clothing and food, but there is nothing for entertainment.

In a room outside the prison, a huge virtual screen was showing images in the prison. Chu Nan was taking a shower on the screen. He seemed to have no idea that his every move was closely monitored. Even though there was no obstruction in the prison, he was still very calm and did not see any embarrassment.

"You said... how many days can he last like this?" In the room, an elderly man wearing traditional Dickland royal costume suddenly asked.

The others in the room looked at each other. An old man with a long pointed face and sparse hair, looking like he was probably over seventy, shook his head and responded: "It is not possible to observe for the time being. Judging from the surveillance situation these days, he has no signs of claustrophobia. All actions are normal, so it is not possible to judge how long he can hold on for the time being."

"Ha, Professor Fenerbar, what can't be seen?" Another middle-aged man next to him, with a fat, greasy face, looked like he was about fifty years old and pushed his decorative glasses clipped to the bridge of his nose, and his tone was full of mockery. "Although this guy seems to be in a normal state now, I'm sure his mental state is actually on the verge of collapse."

If anyone familiar with the psychology discipline of Dickland Empire is here, he will be shocked.

Because the professor Fenerbahce who spoke before was the most famous psychology master in the Dickland Empire now. Not only the Dickland Empire, but also many countries in the Milky Way will include the psychology textbooks he compiled.

The fat man who made a mockery later was not simple. He is a new generation of psychology masters who have gained fame in the Dickland Empire in recent years and has the title of "psychological magician". He is named Cleveland.

Compared with Professor Fenerbahce, his reputation in the academic world is quite different, but in the hearts of ordinary people, his reputation is much greater and he can almost be called a star-level figure.

"Why are you sure?" asked the elderly man wearing Dickland's traditional royal costume.

When facing Professor Fenerbahce, Cleveland could still act sarcastically and disdainful, but when facing the old man, he immediately showed respect.

"Your Highness, according to my research, people who are forced to close in confinement environments generally show two symptoms. The first is to be irritable and irritable at the beginning, and as the emotions arrive, they quickly slide down, and finally become very silent and quiet. The other is to be very calm at the beginning, but in the end they will suddenly collapse and be extremely extreme. It can even be called hysteria, which is very close to the traditional "madman". Chu Nan's performance a few days ago is completely consistent with the characteristics of the second type of person, so I judge that he will burst out due to mental breakdown at any time. It is best to be careful of his violent attack in this situation."

The old man nodded and turned right to Professor Fenerbahce and asked, "What about your opinion?"

Professor Fenerbahce's attitude towards the old man should be more calm, far less humble than Cleveland. Hearing this, he looked at Chu Nan's movements on the virtual screen for a while, and then replied: "I don't agree with Cleveland's judgment. Chu Nan's movements so far do not show any signs of collapse. I don't think he will collapse easily."

Speaking of this, he suddenly bowed to the old man.

"Prince Ferwood, I hope to study him more deeply. If I can study it carefully for a while, I believe that I can obtain very valuable information in my psychology research."

"Don't think about this. If he can spend it safely this time, he probably won't have time to do any research for you in the future. If not, there will be even less chance." The old man waved his hand. "I have told you the purpose of letting you come this time in advance. Now you answer me, what method can I use to let him tell you what he knows honestly?"

"There are many ways." Cleveland immediately rushed to answer. "The method of confinement is not very good now, because this may lead to mental breakdown, and the confidence gained from him afterwards will appear incomplete. We can completely try..."

Cleveland spoke eloquently and said a lot, and it took more than ten minutes to stop.

After listening, the old man nodded without saying anything more, turned to Professor Fenerbahce and asked, "What do you think?"

Professor Fenerbahce frowned and looked at Chu Nan on the virtual screen, turned around and asked, "Have you tried to directly stimulate the drug?"

Cleveland next to him made a hilarious laughter.

"Hey, Professor Fenerbahce, what the prince needs is to break through his psychological defense and obtain complete brain information. Do you actually recommend using drug stimulation directly? Don't tell me that you don't know that drug stimulation will cause unpredictable damage to the brain. If you do this, if such a result occurs, wouldn't all your efforts be wasted? I think..."

"I haven't asked you now." The old man interrupted Cleveland with an expressionless face.

Cleveland's throat was blocked with a word, and his already red face turned redder, but he didn't dare to refute anything to the old man. He could only hold it back and lower his head.

"There is certain that drug stimulation has no effect on him." The old man did not explain too much, but continued to ask: "Is there no other way besides drug stimulation?"

"If the drug does not stimulate it, I'm afraid that we can only take more primitive measures." Professor Fenerbahce frowned even more. "It's obvious that the pain will not have much impact on him. Do he have people and things he cares about? It should be more effective from these."

The old man also frowned: "What about besides these?"

"Not these are good?" Professor Fenerbahce frowned, thought for a while, and asked, "Can I let me talk to him in person? He is not old after all, and I should be able to break through his psychological defense and try to let him reveal useful information."

"No, you are not qualified to contact the things he knows." The old man shook his head without hesitation and refused.

Professor Fenerbahce and Cleveland were both surprised.

The two looked at Chu Nan on the virtual screen, and were surprised.

What did this young boy do? He actually knows something that the imperial royal family attaches so much importance to?

"If I can't talk to him in person directly, I can't accurately judge his psychological condition, so I can't give an accurate answer." Professor Fenerbahce said helplessly. "This young man's mind is very firm, and ordinary methods may not be effective."

The old man also frowned, turned to look at Chu Nan on the virtual screen, thought for a while, and looked at Cleveland.

"Say the methods you just said again."

Cleveland was immediately overjoyed.898)
