"Professor Sun," Lin Gang stepped forward and shook hands very politely: "I haven't seen you for a long time, I'm going to trouble you again this time."

"Xiao Lin, why are you being polite to me?" Professor Sun was over sixty years old and full of silver hair, but he was in high spirits: "Didn't Team Leader Wang come this time?"

Lin Gang shook his head: "The team leader is staring at a big eucalyptus recently, and I will handle the matter here."

"However," Lin Gang turned sideways and let Chen Yan behind him: "The boss sent me a strong general to support me."

"Chen Yan, this is Professor Sun Muzhi, a psychology professor at the highest university in China, an expert-level national treasure, and his specialty is in the field of hypnosis."

"It's the special advisor of our National Detective Corps!"

ho!

With this series of titles, Chen Yan knew that Professor Sun Muzhi was very powerful just by hearing it.

What's more, he is a special advisor to the National Detective Corps.

Compared with him, the special advisor of the Liao Provincial Detective Team, he is a big level higher.

"Hello, Professor Sun," Chen Yan hurriedly stepped forward and saluted, "I'm Chen Yan of Liancheng Detective Team, it's an honor to meet you."

"Chen Yan?" Sun Muzhi smiled slightly: "Xiao Lin told me about you on the phone just now."

"At a young age, he has won many merits, and he is already the deputy captain of a detective team, Captain Chen, that's amazing!"

"Professor Sun, you're welcome," Chen Yan smiled politely: "I'm not a captain. If you don't dislike it, just call me Xiao Chen."

Along the way, Chen Yan could see that Lin Gang respected Professor Sun very much.

Even, it is not an exaggeration to be cautious.

However, Professor Sun seems to be more interested in Chen Yan: "What does Xiao Chen think about this eucalyptus?"

Before inviting Professor Sun Muzhi over, Lin Gang had already sent the relevant materials.

Therefore, Professor Sun Muzhi is already familiar with these four suicide cases.

Especially the situation of Xu Dongtian, the materials have made a detailed introduction, and there are even a lot of videos.

Speaking of eucalyptus, the smile on Chen Yan's face disappeared.

"Professor Sun, I have big doubts about this eucalyptus."

Chen Yan took out a tablet and handed it to Sun Muzhi: "Professor Sun, this is Xu Dongtian's reaction after watching the video."

"From the analysis of his pupils, expressions and behavior, the other party should have entered a state of hypnosis."

"Also, it should be in a state of deep hypnosis."

"However, I also checked some information, and it is impossible for hypnosis to cause the hypnotized person to behave against the laws of biology."

"Such as suicide, not to mention masochistic suicide."

"However, the facts tell us that the other party has done just that."

Sun Muzhi nodded: "Xiao Chen is right."

"I've already watched Xu Dongtian's video."

"The other party's state at the time was a very obvious stressful deep hypnosis."

Sun Muzhi pointed to the picture in the video: "Look, Xu Dongtian's pupils are rapidly shrinking and dilating. This is a sign that his consciousness is dormant and his consciousness is awakening."

"The other party is a master, very proficient in hypnosis."

Professor Sun Muzhi showed Chen Yan the flat-panel video: "Of course, all this is just an appearance."

"What I can tell you for sure is that Xu Dongtian's current appearance is in line with the characteristics of deep hypnosis."

Professor Sun Muzhi paused, then continued: "As for the other thing, as Xiao Chen said, the other party just relies on hypnosis, no matter what method, it is impossible for the hypnotized person to commit suicide by self-abuse. degree, but…”

Sun Muzhi looked at the video of Xu Dongtian's drug addiction attack: "If you combine some drugs, it is possible to do this!"

drug?

Lin Gang frowned, Chen Yan did the same.

Xu Dongtian's highly hallucinogenic drug addiction has been identified.

Now, the blood and urine analysis of Yin Chengwen and Gao Tiancheng are in progress, and there is no news yet.

"If that's the case," Chen Yan has another doubt: "Professor Sun, is there any way to make people enter a hypnotic state in an instant, and then cooperate with the effect of drugs to achieve similar effects?"

Sun Muzhi shook his head: "Judging from the current hypnosis methods and techniques, there is nothing that can make people enter a hypnotic state in an instant."

"The phenomenon of instantly entering hypnosis does exist," Sun Muzhi continued, "However, the premise is that you have undergone long-term hypnosis training."

"Let the hypnotized person be familiar with certain hypnotic conditions, and it is possible to be hypnotized instantly."

...

After Professor Sun's popularization, Chen Yan and Lin Gang have learned a lot about the process and effects of hypnosis.

After setting up Sun Muzhi, Chen Yan and Lin Gang returned to the Kun City Detective Team.

"Brother Lin, according to Professor Sun, these four people should have received hypnosis training?"

Lin Gang nodded: "But, we have almost checked the past of the four of them."

"There is basically no intersection..."

"I found it!"

"The body fluid examination of Lin Group, Chen Group and Wang Hu is impossible, but the blood and urine analysis of Yin Chengwen and Gao Tiancheng have been completed!"

Although the two have been dead for a long time, the body fluids have been collected at that time.

Just to do a similar check in the future.

After taking the report, Chen Yan was excited!

"really!"

In the test report, trace amounts of unknown drug ingredients consistent with Xu Dongtian's body were also found in the body fluids of Yin Chengwen and Gao Tiancheng.

"Team Leader Chen," the detective who followed up the test also flushed with excitement: "The content is very small, if it were not for the comparison of the drug components detected in Xu Dongtian's body, we would not be able to find it!"

...

Standing in front of the eucalyptus analysis panel, Chen Yan fell into contemplation.

Not to mention Wang Hu for the time being, his body has been cremated, leaving no clues.

And the remaining three.

Why did the murderer kill these three people?

This is what Chen Yan needs to figure out.

Only by figuring out the cause can we infer what happened later.

Because they knew about the existence of the drug, and silenced?

Obviously not, Xu Dongtian didn't even know that he was addicted to drugs before he was discovered.

Therefore, it is impossible for these three people to actively reveal the existence of the drug.

After all, these three people, at least Xu Dongtian who hasn't died yet, doesn't even know that he sucks.

Since it's not to hide the existence of drugs, why kill people?

The task of experimenting with new products has been completed, hiding the existence of new products, or the existence of experiments?

There is a possibility of this.

However, Xu Dongtian has clearly exposed the fact that he is addicted to drugs, and there is no way to hide it...

and many more!

wrong!

Xu Dongtian's suicide was unsuccessful. If he succeeded in suicide the day before yesterday, his drug addiction would not have been exposed!

It was because of the failure of suicide that Xu Dongcai exposed the situation of drug addiction.

This allowed the special team to grasp this clue.

So, the death of Yin Chengwen and Gao Tiancheng is to hide the truth of their history of highly hallucinogenic drug addiction?

Yes, it makes sense.

However, how did the other party judge that Yin Chengwen, Gao Tiancheng, and even Xu Dongtian would expose drug addiction.

After all, according to Xu Dongtian's situation, they don't even know that they are addicted to drugs.

Hypnosis...drugs...addiction...exposure...

Hypnosis plus medication?

Suddenly, Professor Sun Muzhi's words echoed in Chen Yan's mind.

Like a flash of lightning!

Gan!

Why did Xu Dongtian suffer from drug addiction?

Isn't it just medicine?

If he has been taking duds, he will definitely not become addicted.

And the heuristic condition of hypnosis, if it is set to lack of drugs, you will commit suicide when you see the game screen, can you explain it?

Thinking of this, Chen Yan immediately called Professor Sun Muzhi's phone.

"Professor Sun, if, I mean if, a hypnotist, the content of a certain drug is the trigger threshold Once the content of the drug in someone's body is lower than a certain value, plus the game's Stimulation, will there be a deep hypnosis like Xu Dongtian?"

On the other side of the phone, Sun Muzhi frowned in thought.

After half an hour.

"It's theoretically possible."

"If a person takes a certain drug for a long time and receives a certain hypnosis for a long time, it is possible for a hypnotist to control the content of the drug as a starting condition for hypnosis."

"However, there are preconditions for this..."

Chen Yan answered immediately: "Does it take time?"

"Yes, it takes time to train, at least a few months to do it."

what!

Putting down the phone, Chen Yan looked excited.

What is the scariest thing.

The unknown is the scariest.

For example, the suicide of Wang Hu and the others.

Suddenly, he went crazy and ended his life madly.

Anyone who sees it finds it scary.

However, once exposed the possibility of such behavior behind the scenes.

Everything is back to square one.

Four of them, if they really followed Chen Yan's reasoning, eventually committed suicide.

Then, as Professor Sun Muzhi said, after a long period of hypnosis and drug training, it is possible for them to instantly achieve the effect of masochistic suicide.

So, the origin is where are they trained in hypnosis?

Who hypnotized them?

When the detective solves the case, it is essentially playing a game of hide-and-seek.

The murderer left clues, and according to the clues, the detectives found them in the vast crowd!

The difference is whether the murderer leaves more or less clues.

Whether stealth is low or high.

And this wave of hide-and-seek, the murderer is obviously clever.
