Du Yiyi's words are so realistic, so realistic that Cheng Jiayi didn't want to find an excuse to refute it.

To say that the killing at the beginning of the chaos was to survive, it was helpless, Liu Heizi did have a bit of a meaning to kill for the sake of killing, and she knew clearly in her heart that it couldn't all be pushed on leaving the research institute in exchange for her father.

The same was true of the subsequent slaughter of birds.

She does have the intention of finding a suitable person or something to kill in order to satisfy her desire to kill.

Du Yiyi didn't say anything, and Cheng Jiayi didn't want to think about it, and even deliberately avoided it in his heart. But now that Du Yiyi has made the facts clear, Cheng Jiayi has no choice but to face the facts.

As Du Yiyi said, Cheng Jiayi knew that she couldn't bear the blow of knowing the facts, she just subconsciously avoided it.

She really liked killing, and she also liked the exhilarating feeling that it brings.

Professor Still looked at her son in amazement, even though she knew that Yiyi had her own opinions, but she had observed so carefully and came to conclusions that were close to research, which still made her feel complicated beyond words.

How attentive you have to Cheng Jiayi is to discover these things that even Cheng Jiayi herself has not noticed. Thinking that Yiyi and Cheng Jiayi might really be in love, the professor's heart couldn't help but be sour.

But immediately, the identity of a medical worker replaced the mother's thoughts, and the professor still whispered: "Maybe, not so. ”

Du Yiyi and Cheng Jiayi both looked up and looked still.

Professor Still looked at Du Yiyi: "The environment can change people's thinking, the dependence of the surrounding people, the sense of responsibility, the atmosphere at the time, and a few words from bystanders can all stimulate a certain impulse."

Judging from the environment you are in, Jiayi's killing actions can also be attributed to the influence of the environment and the admiration of the people around you. From a psychological point of view, this age is the most susceptible to external influences and interventions. ”

The professor still paused, waiting for Du Yiyi and Cheng Jiayi to digest and understand.

Du Yiyi asked, "Mom, do you think that these things that Jiayi did were not because of the influence of crystals?" ”

Professor Still pondered: "There is no specific comparative test, and I can only tell my own opinion from what I have seen and what you have said." ”

Du Yiyi couldn't help but laugh and said, "Mom, you don't have to be so cautious with us, Jiayi won't mind what you say." ”

Cheng Jiayi also showed a shallow smile: "Auntie, your opinion should be extremely useful to us, and we are also willing to listen to your opinion." ”

Professor Still nodded: "In that case, I'll also tell you what I think, starting from the first time I saw you in the hospital." ”

"When we met that day, everything was normal, and I didn't know that you had killed someone during the day. That day, Jiayi, did you hesitate when you killed someone? ”

Cheng Jiayi squinted his eyes and recalled: "At that time, when I was dragged into the room, I smelled blood, and then ...... I didn't have any hesitation at the time. ”

Du Yiyi interjected one by one and explained for Cheng Jiayi: "Mom, Jiayi and I have seen a lot of doomsday before, and we have discussed it together. Mom, you don't know how dirty some men are written in those apocalypse. In that case, if I had been murderous, I would have had the intention of killing. ”

Professor Still nodded, but looked at Cheng Jiayi and said, "At that time, just because that man smelled of blood in his house, you first judged that there was a murder in his house.

Then the man's actions also showed his ill intentions towards you, so in fact, you had already prepared for the worst when you were pulled into the room by the man. ”

Cheng Jiayi thought about it and nodded.

"It turns out that your judgment is not wrong, that man killed his wife first, and he is a person who should be killed." The professor was still worried that Cheng Jiayi would misunderstand his statement, so he affirmed it before continuing:

"But it also shows that the time you killed someone was not affected by the crystal, but the environment and danger that prompted you to do what was most beneficial to you."

Cheng Jiayi and Du Yiyi both nodded slightly.

Professor Still continued: "You arrived at the hospital that night, and then you encountered a sudden mutation, and I twisted my feet and carried me one by one. ”

Professor Still said, turning his head to look at Du Yiyi: "Yiyi, if I hadn't twisted my foot at that time, would you have killed someone?" ”

Du Yi was stunned and said, "Yes, absolutely." ”

The professor nodded again: "Yes, in times of crisis, people are often forced to bring out their potential. In particular, you have discussed what will happen after the end of the world, and what you have subconsciously discussed will be confirmed in reality.

To be honest, I was really shocked when I saw Jiayi make a move, but I was also infected at that time...... If it weren't for what I just said, I wouldn't have thought of many things. ”

Du Yiyi groaned one by one: "Mom, but those two times were forced to do so, Jiayi will be killed if he doesn't kill someone." ”

The professor still said: "Yes, those two times were indeed the case, Jiayi should be decisive, not only to protect himself, but also to protect you and me." Jiayi, after those two times, do you have more confidence in yourself? ”

Cheng Jiayi nodded.

"You've seen something similar to Yiyi before, even if you don't believe all the content, but since you've discussed it, you're still subconsciously affected, right?"

Cheng Jiayi nodded again.

"Then, you and Yiyi are faced with a burglary. Jiayi, there's a question I've always wanted to ask you, if my question offends you, can you just treat it as if it were a medical worker's job? ”

Cheng Jiayi looked at Professor Still strangely and said, "Auntie, what do you want to ask me, I have always admired you." ”

Professor Still shook his head and said, "When you say that, I feel more and more that I shouldn't ask. ”

Cheng Jiayi didn't know how to answer, so she had to look at Du Yiyi as if asking for help.

Du Yiyi: "Mom, Jiayi won't care, even if you are so polite, I also feel awkward." ”

The professor still smiled, "Okay, I'm welcome." Jiayi, can you tell me what kind of thoughts you had in mind at that time, when you went and smashed the heads of those two people to see if there were any crystals? ”

After a pause, Professor Still continued: "Yiyi was still by your side at the time, you were still a girl, it stands to reason that you should either do it with Yiyi or let Yiyi do it yourself." ”

Cheng Jiayi was stunned, it was too long, she forgot what she thought about that day, and now in retrospect, only a vague feeling remained.

yes, why did she do it herself? Isn't she afraid?

"I probably think I've killed someone." Cheng Jiayi muttered after a while.

"One by one, I also did it." Still the professor pressed a sentence.
