Chen Yan reported his reasoning to Lin Gang.

Lin Gang nodded: "Your reasoning makes sense."

"Our original next step is to trace the source of the drug and break the chain. This can be considered a complete conclusion."

Lin Gang originally wanted to get clues from Zhang Cunshu.

After all, it would be impossible for him to advance drug trials alone.

At the very least, the source of medicine is not so simple.

Moreover, in Zhang Cunshu's clinic, Lin Gang and the others did not find any residual drugs.

Only the blue transparent vial that Chen Yan found.

This is kind of weird.

In a new drug test den, there was no drug left.

It doesn't make sense.

So, when they do drug trials, where do the drugs come from?

who sent it?

Is it local production or smuggled from Yang Kingdom.

This is all suspicious.

Since Lin Gang and Chen Yan have reached a consensus, the next work is to move forward.

To Chen Yan and Lin Gang's surprise, Li Yuling's interrogation went very poorly.

Since Li Yuling was arrested, she has been intent on committing suicide.

Not cooperating at all.

Lin Gang couldn't use special means to ask questions. For example, the medicine used by the senior officials of the US-Japan International Hospital cannot be used here.

Although that thing can reveal the truth of the suspect, it does too much damage to the brain.

After Li Yuling used the drug, it would be fine if she explained everything, but if she didn't explain it comprehensively, she would become an idiot, and the follow-up work would not be able to be carried out.

So, now is the time for professionals.

Professor Sun Muzhi.

This psychologist, who is good at hypnosis, was originally responsible for interrogation in the National Detective Corps.

However, his interrogation method is a bit special.

...

Monitor indoors.

Professor Sun Muzhi has been invited by Lin Gang: "Professor Sun, I will trouble you next time."

Professor Sun Muzhi has not been idle either, and has been studying the video recording of Zhang Cunshu's enslavement of Li Yuling.

"I'm here to help you!"

After Sun Muzhi smiled and patted Lin Gang on the shoulder, he turned to look at Chen Yan: "Xiao Chen, I have probably finished researching the video you asked me to watch."

Research done?

After Chen Yan speculated that Li Yuling might reverse hypnotize Zhang Cunshu, he contacted Professor Sun Muzhi to view the video.

"Professor Sun, what's the result?"

If Chen Yan's guess is correct, it proves that Li Yuling is one of the main culprits, and there may be a bigger black hand behind it.

"Probably have eyes and eyes," Professor Sun Muzhi nodded: "Zhang Cunshu's hypnosis technique is very powerful, and it is a variant of a very profound hypnosis technique in Yanguo."

"According to common sense, it is unlikely that Li Yuling could reverse hypnotize Zhang Cunshu with this hypnotic technique and the influence of some drugs."

Chen Yan frowned: "You mean, Li Yuling was really hypnotized by Zhang Cunshu?"

Professor Sun Muzhi nodded: "There should be no doubt about this."

"In the video, Li Yuling's characteristics of being hypnotized are very obvious, and the reaction is much stronger than that of Wang Hu and others after being hypnotized. This is difficult to hide in the eyes of our professionals."

"Also, Li Yuling should not understand hypnosis. She did not show any hypnotic techniques in the video."

call……

Chen Yan let out a long breath.

It seems that his reasoning has gone wrong.

"But, Professor Sun," although Chen Yan believed in Professor Sun Muzhi's judgment, after all, he was a professional, but from the perspective of handling the case, he still had doubts.

"If Li Yuling was really hypnotized, judging from the servile obedience she showed in the video, how could she have killed Zhang Cunshu!"

Chen Yan looked at Li Yuling, who was being monitored, with a solemn expression: "Also, although Li Yuling looks thin, her arms are very strong."

"And the blade in her mouth shows that this woman is not just a helper for Zhang Cunshu's hypnosis."

Chen Yan was deeply touched by this.

When Li Yuling killed Zhang Cunshu, Chen Yanke grabbed Li Yuling's arm.

With Chen Yan's power that has been blessed by the system, Li Yuling is naturally impossible to surpass Chen Yan in power.

However, Chen Yan could clearly feel the strength on Li Yuling's arm.

Strong, stronger than the average adult man.

Moreover, Li Yuling should have a blade in her mouth.

Why?

If not specially trained, ready to kill at any time, what would you do with a blade in your mouth.

In Chen Yan's opinion, Li Yuling was not so much a slave of Zhang Cunshu as she was monitoring Zhang Cunshu.

Its purpose is to kill people at critical moments.

Sun Muzhi paused, he had no way to refute Chen Yan's statement.

"I know your speculation is reasonable," Sun Muzhi still shook his head. "However, the possibility of Li Yuling's reverse control of Zhang Cunshu is indeed infinitely close to zero."

"but……"

Um?

"But what?"

Sun Muzhi turned his head and looked at the figure in the surveillance camera: "This Li Yuling is indeed very strange!"

"However, I need to contact her to give a specific answer."

"That's fine," Lin Gang opened the monitoring room, "I asked you to hypnotize Li Yuling to see if you could find some clues..."

...

after an hour.

Professor Sun Muzhi's hypnotic interrogation is over.

During the hypnosis, Professor Sun Muzhi specifically explained that monitoring cannot be turned on. It's about some secrets.

Lin Gang knew this rule for a long time.

Chen Yan didn't care either. Seeing Professor Sun coming out, he hurried forward: "Professor Sun, how are you?"

Professor Sun Muzhi seemed very tired, wiped the sweat from his forehead and shook his head: "Nothing gained."

No gain?

This time, Lin Gang was shocked.

Who is Sun Muzhi?

He is a psychology expert from the top universities in China and one of the most famous hypnotists in China.

Special advisor to the National Detective Corps.

Over the years, they have helped Wang Min and the others to investigate many major cases.

Now, interrogating a person, there is no gain?

how can that be!

Professor Sun Muzhi also noticed Lin Gang's surprised expression, and smiled weakly.

"Why are you looking at me like that?"

Chen Yan took a cup of tea and handed it to Professor Sun Muzhi, then helped the obviously very tired old man to sit on the sofa.

"Professor Sun, I'm just a little surprised," Lin Gang also sat aside: "I didn't expect that there are people you can't break through."

Professor Sun Muzhi took the teacup: "Old man, I am also a human being, not a god. Of course, there are things I can't do."

After drinking a sip of tea, Professor Sun Muzhi slowed down and continued, "It can't be said that there is no gain at all."

"At least, there is an answer to what Xiao Chen is concerned about..."

...

"Double hypnosis?"

Lin Gang and Chen Yan spoke in unison.

Professor Sun Muzhi nodded: "That's true."

Putting down the teacup, Sun Muzhi got up and looked at the surveillance screen monitoring Li Yuling: "Before Li Yuling was hypnotized by Zhang Cunshu, she had finished a very deep subconscious hypnosis."

"Usually, this hypnotic state and symptoms cannot be manifested unless they touch the activation signal preset by the hypnotist..."

Chen Yan's eyes lit up: "For example, Zhang Cunshu wants to confess?"

"Not bad!" Professor Sun Muzhi nodded: "That's why Li Yuling killed Zhang Cunshu."

"Because Zhang Cunshu's hypnosis and enslavement training on Li Yuling were all conscious."

"In other words, a means of hypnosis that has a lower priority than subconscious hypnosis."

"Once there is a conflict between the two commands, it must be a deep subconscious hypnosis that works."

"That's why I can't get valuable clues from Li Yuling's mouth."

Chen Yan's mind is spinning fast now: "Because, you are also conscious of her hypnosis!"

"And Li Yuling in her conscious state really doesn't know anything, right?"

Professor Sun Muzhi looked at Chen Yan with a somewhat surprised look: "Xiao Chen, you are right, that's what you mean."

"Xiao Lin, your head is not bright, look at Xiao Chen..."

Lin Gang: "..."

What does this have to do with me.

Chen Yan scratched his head: "Professor Sun is very polite."

"By the way, can this subconscious hypnosis be lifted?"

If it can be lifted, then it would be a no-brainer.

Isn't the black hand hidden behind Li Yuling exposed?

"Removing it is possible to contact," Teacher Sun Muzhi nodded, "But it will take a long time."

"How long?"

"At least half a year!"

half a year?

After half a year, the day lily will be cold.

The other party is estimated to have already run away.

"Professor Sun, is there no other way?"

Lin Gang also knew that if he waited half a year, there might be many more people to be killed.

Sun Muzhi shook his head: "This is already a very fast speed. The subconscious's deep hypnosis is generally difficult to recover after it is used."

"I'm talking about half a year, just to restore Li Yuling to a normal person. If you restore the memory of being hypnotized at the same time, it will be more than ten times more difficult!"

...

Well, this road is basically blocked.

As for the prescription to control Li Yuling's speech with medication, it was also denied by Professor Sun Muzhi.

The drugs of the Detective Corps are easy to use, but compared with Professor Sun Muzhi, they are not even a star.

He can't do anything, let alone drugs.

After all, Professor Sun Muzhi also participated in the research and development of that drug...

The thread... interrupted.
