Chen Chen walked out of Zheng Jian's office.
His expression was as usual. No one could tell that he had just argued with an associate professor half a minute ago.
Chen Chen walked down the stairs to the first floor, walked out of the lobby, and walked out of the office building.
At this point, Chen Chen took out his phone and looked at the time.
It was exactly 10 o 'clock sharp.
"Time... It's time."
Chen Chen murmured and then walked toward the dormitory.
When he had walked more than ten meters away, there was a sudden "thud" behind him.
It was as if something soft but heavy had fallen from the top of the building.
The passersby were silent for a moment, but then, there was a sudden burst of screams.
The entire campus was in an uproar...
Chen Chen did not look back. He chose to leave immediately.
Before this, Chen Chen was not sure if Zheng Jian had killed Zheng Jian's wife.
However, sometimes, there was no need for confirmation. A suspicion was enough.
As for why Chen Chen was suspicious?
It was simple.
First of all, medulloblastoma was not a common disease for people of Zheng Jian's wife's age. It was a malignant glioma of the posterior cranial fossa that often occurred in children. It was not common in adults.
Of course, Chen Chen would not have thought of this based on this alone. However, one should not forget Zheng Jian's identity.
Zheng Jian was a double doctorate in biochemistry and pharmacy. He was also a teacher at the Institute of Biological Sciences.
To put it simply, he had sufficient skills and conditions to obtain his wife's somatic cells at any time, induce them to generate cancer cells in the laboratory, and finally inject them back into his wife's body.
This was why Chen Chen asked a question like "Do you often give your wife an IV drip at home?"
Of course, these two points alone did not prove anything. Zheng Jian still needed a motive to kill his wife.
In that case, his second wife, the daughter of a high-ranking official, was the motive.
To put it simply, this was a crappy script of a scumbag abandoning his work after achieving success and choosing a woman with a more promising future as his wife.
Since he had a motive, he only needed to reverse engineer it and naturally conclude that Zheng Jian killed his wife.
However, this was only a guess. The real reason Chen Chen came to this conclusion was the photo he had placed in his office.
According to criminal psychology, this was a psychological compensation effect.
By placing a photo of his ex-wife on his desk, one, he could reduce the guilt in his heart.
Secondly, it could also make the people around him feel that he cherished his ex-wife very much and reduce the suspicion of him committing a crime.
However, humans were not cold-blooded animals after all. For many years, it was immorality that bound everyone. That threshold was not something that anyone could easily overcome.
Therefore, although Zheng Jian had successfully killed his wife, his heart was not at peace.
The fear of being exposed, the guilt he felt towards his wife, and the condemnation of his conscience constantly plagued him. He didn't even dare to see a psychiatrist.
This had been a thorn in his side for many years.
Later, the disease even made him fear his dead wife, which led to the previous scene.
Although there was a photo of his ex-wife on his desk, the photo was facing away from him …
At this point, Chen Chen's guess had a sixty percent chance of being correct.
Don't think that 60% is not a lot. In the world, other than some inevitable events such as "the sun rises from the east", "water flows to the bottom", "objects fall instead of rising", and so on, most of the world's events are random events with a certain probability.
A sixty percent chance was enough for Chen Chen to take a gamble.
Therefore, after Chen Chen entered Zheng Jian's office, the first thing he did was to show a submissive attitude to lower the other party's guard.
After that, he used the method of fiddling with the desk clock to plant a "seed" in Zheng Jian's mind.
This was a common form of hypnosis.
The human consciousness was divided into the surface consciousness and the subconscious. In general, when one was awake, the surface consciousness was dominant.
The so-called hypnosis was to induce the patient into a light sleep through guidance and suggestion. At this time, the subconscious would be released and the hypnotist could bypass the conscious and directly communicate with the patient's subconscious.
This was also why Chen Chen sent the information to Zheng Jian directly. He wanted Zheng Jian to completely let down his guard.
However, even at this point, Chen Chen still could not hypnotize Zheng Jian.
Although the concept of hypnosis was very mysterious, it was the same thing in the end. If a psychiatrist wanted to hypnotize a person, he must have the person's active cooperation. Otherwise, everything would be in vain.
Moreover, Chen Chen understood that no matter how submissive he was, Zheng Jian would not completely let down his guard.
However, this was only the first step for Chen Chen.
The second step was that the desk clock would chime the time.
When the desk clock chimed the time, Chen Chen raised the question of "who is the woman in the photo". This step made Zheng Jian subconsciously associate the desk clock with his ex-wife.
However, because Chen Chen had moved the desk clock forward by five minutes, it was only 9: 55 at that time. Therefore, Chen Chen moved the desk clock back and at the same time, deepened the impression of the "seed" in Zheng Jian's mind.
Following that was the third step.
Chen Chen suddenly made things difficult and questioned Zheng Jian about the cause of his wife's death. This kind of extreme contrast would usually catch the other party off guard.
Moreover, the interrogation question made him even more flustered and shocked.
This was why Zheng Jian was so angry.
Because sometimes, the expression of anger was actually a cover for a guilty conscience when people were caught off guard.
At the same time, Chen Chen laid his cards on the table again and took the initiative to tell Zheng Jian that he was going to hypnotize him.
Although this step made Zheng Jian completely vigilant, it was also a hint to Zheng Jian at the same time.
It was this hint that planted the seed of "I might be hypnotized" in Zheng Jian's mind.
Then, it was the final step.
Chen Chen deliberately made movements to hypnotize Zheng Jian, causing Zheng Jian's mind to be highly tense. Then, he suddenly made a mistake and dropped the photo frame on the ground.
At this time, Zheng Jian's first thought was – Chen Chen's method of hypnotizing him had failed.
Finally, Chen Chen turned around and left.
Seeing that the person who questioned him had left, Zheng Jian's tense will instantly relaxed. His will experienced a high-intensity change from relaxation, tension, high tension, and relaxation again in a few short minutes.
It was like going through a roller coaster. Zheng Jian's spiritual will was completely exhausted.
This was when Chen Chen's final blow came!
"Dong!"
A clock chimed, like the trigger of a pistol being pulled.
At this moment, the seed buried in Zheng Jian's heart completely erupted, igniting the fear and guilt that had been buried in his heart for many years!
Like a flash flood, under Chen Chen's hypnosis, Zheng Jian leaped from the fifth floor and ended his sinful life...
Everything was that simple.
However, he was really decisive. He killed a living person just like that.
Chen Chen thought silently.
