Chen Yan reported his reasoning to Lin Gang.

Lin Gang nodded: "Your reasoning makes sense."

"Our next step was to trace the source of the drugs and break the chain. Only then can the case be completely closed."

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 drugs is not that simple.

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

Only the blue transparent vial found by Chen Yan.

This is a little weird.

In a new drug testing site, not a single drug was left.

This doesn't make sense.

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

Who sent it?

Is it made locally or smuggled from Yang Kingdom?

These are all doubtful.

Now that Lin Gang and Chen Yan have reached a consensus, the next step is to move forward.

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

Ever since Li Yuling was arrested, she has been obsessed with committing suicide.

Not cooperative at all.

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

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

After Li Yuling took the drug, it would be fine if she fully explained it, but if she did not fully explain it and became an idiot, the follow-up work would not be carried out.

So, now it’s time for professionals to take action.

Professor Sun Muzhi.

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

However, his interrogation method is somewhat special.

…

Monitoring room.

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

Professor Sun Muzhi has not been idle either, and has been studying the video records of Zhang Cunshu enslaving Li Yuling.

"I'm just here to help you!"

Sun Muzhi smiled and patted Lin Gang's shoulder, then turned to look at Chen Yan: "Xiao Chen, I've probably finished studying the video you asked me to watch."

Finished the research?

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

"Professor Sun, what was 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.

"I guess I have some clues," Professor Sun Muzhi nodded: "Zhang Cunshu's hypnosis technique is very powerful. It is a variant of a very advanced hypnosis technique from the Yang Kingdom."

"According to common sense, with this kind of hypnosis technique and the influence of some drugs, it is unlikely that Li Yuling can reversely hypnotize Zhang Cunshu."

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

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

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

"Moreover, Li Yuling probably doesn't understand hypnosis. She didn't show any hypnosis techniques in the video."

call……

Chen Yan let out a long breath.

It seems that his reasoning has gone awry.

"But, Professor Sun," although Chen Yan believed in Professor Sun Muzhi's judgment, he was a professional after all, 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 kill Zhang Cunshu!"

Chen Yan looked at Li Yuling who was under surveillance with a solemn expression: "Although Li Yuling looks thin, her arms are very powerful."

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

Chen Yan was deeply touched by this point.

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

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

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

Very strong, stronger than the average adult man.

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

Why?

If he hadn't gone through special training and was ready to kill at any time, what would he be doing with a blade in his mouth?

In Chen Yan's view, Li Yuling was more like monitoring Zhang Cunshu than Zhang Cunshu's slave.

Its purpose is to kill people and silence them 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 controlling Zhang Cunshu in reverse is indeed infinitely close to zero."

"but……"

Um?

"But what?"

Gufu

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

"But I need to get in touch with her before I can give a specific answer."

"That's no problem." Lin Gang opened the monitoring room: "I originally asked you to hypnotize this Li Yuling to see if you can find some clues..."

…

An hour later.

Professor Sun Muzhi's hypnosis interrogation is over.

During the hypnosis period, Professor Sun Muzhi specifically stated that monitoring cannot be turned on. This involves some secrets.

Lin Gang already knew this rule.

Chen Yan didn't care. When he saw Professor Sun coming out, he quickly stepped forward: "Professor Sun, how are you?"

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

No gain?

At this time, Lin Gang was shocked.

Who is Sun Muzhi?

A psychology expert from the top university in China and one of the most famous hypnosis masters in the country.

Special Advisor to the National Detective Corps.

Over the years, I have helped Wang Min and others investigate many major and important cases.

Now, there is nothing gained from interrogating a person?

How is this possible!

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

"Why are you looking at me like this?"

Chen Yan handed a cup of tea to Professor Sun Muzhi, and then helped the obviously very tired old man 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 who you can't break through."

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