In the dark villa, "Qing Xiran" talks about the principles of a bunch of crystal core reactors. In summary, crystal cores are actually a substance that can grow on their own, as long as the "soil" is suitable or the radiation is strong enough.

Crystal nuclear ore veins can make their natural growth difficult. When there are enough crystal nuclei, the crystal nuclei can release a kind of radiation. The radiation of the crystal nuclei interacts with the external radiation and can continue to grow.

The more crystal nucleus reactors, the faster the growth rate of crystal nucleus, and the smaller the crystal nucleus reactor, the slower the growth rate of crystal nucleus.

This is one of the reasons why "Qing Xiran" is not in a hurry to develop the crystal nuclear vein in Jinxian Village. She is raising this vein to make it grow thicker and thicker.

"The so-called 'soil' has extremely harsh conditions for forming. On this planet, Feihua Bio has not yet discovered a naturally formed crystal nuclear vein."

"Qing Xiran" looked at Zhai Fan. She only talked about Feihua Bio, but did not say that she was herself. Feihua Bio did not find the ore veins, but she found it, and this did not lie.

Looking at Zhai Fan again, as Qing Xiran said, his brows became tighter and tighter, and he asked:

"Crystal nuclei grow in the brains of those animals. Is this related to the crystal nuclei reactor?"

He vaguely understood something. With his brain, he couldn't understand such a complex principle of crystal nuclear reactors. But humans are originally a high-level animal. Crystal nuclei will grow in the brains of low-end animals. Humans will definitely do it too. Low-end animals will mutate. Don't humans also have psychics?

"Your question is very good."

"Qing Xiran" whose body was still motionless looked at Zhai Fan and said to him:

"You can sit down, I'll let you see the real scenes in Feihua Bio's biological factory, and then slowly talk to you."

Zhai Fan hesitated for a moment, but still chose to walk to the leather sofa next to him and sit down.

"Qing Xiran" with a slight stiff feeling during the action turned his head and a screen lit up opposite the sofa where Zhai Fan was sitting. On the screen was the internal camera of Feihua Bio Factory, which was photographed about the tragic situation of the human crystal nuclear reactor.

It was a reactor like a round pot, old man, woman, man, teenager... Among them, there were pregnant women, such a large number of people, crying and screaming, were driven into the reactor.

I heard "Qing Xiran" standing behind Zhai Fan's sofa chair and explained:

"Crystal nuclei will grow in the brain of animals, and human brains will also be in the brain. In the first year of the apocalypse, a human-shaped mutant monster appeared in the eastern district of Xiangcheng, which was mutated by humans. Oh, in the novel, they called zombies. At that time, Mu Fengliang, the commander-in-chief of the city system of Xiangcheng, broke into that catastrophe. Later, I asked the anatomical experts to dissect several such zombies and found the crystal nuclei from their brains. It was not big, but at least there were."

Zhai Fan's eyes widened and looked at the picture in front of him in disbelief. What a century has it been, and such a tragic biological factory can still appear. He sat on the sofa, his fists were pinched tightly, and the veins on his fists were exposed.

"The principle I analyzed is that a type of species has multiple directions of mutation, so we can see a variety of mutation monsters in this apocalypse, which have never been heard of or seen in the past. Humans naturally have multiple mutation directions, becoming ordinary people, or psychics, or mutating into zombies. This is just a radiation effect on everyone's body and a different reaction."

"Qing Xiran" slowly bent down, and said with unconscious eyes behind Zhai Fan's forehead:

"So, among humans, there is a kind of human brain that can grow crystal nuclei infinitely, which is the natural 'soil' of the crystal nucleus ore veins."

Zhai Fan shook all over and sweated coldly on his forehead. With the screams of men, women, young and old, she slowly turned around and looked at "Qing Xiran" behind him. She wanted to smile at him, but the expression on her face was really stiff. With lifeless eyes, the smile expression made by her smile seemed extremely creepy.

This made Zhai Fan, a person who was not afraid of heaven and earth, and who was not afraid of death, feel a sense of creepy in his heart. His butt moved and he was discomfortably away from some of the "Qing Xiran" behind him.

Then he asked, "Why did Feihua Bio catch you?"

He thought he had already known the answer. He said so much tonight. It seemed that "Qing Xiran" was talking about fragments and had nothing to do with it, but in fact, every word she said was not nonsense, it was all related.

"Qing Xiran" smiled sneer again and continued:

"The wider the brain, the better the quality of the 'soil'. That is what humans call smart people. As long as they are given strong radiation, crystal nuclei can grow in their brains. People with good brains can grow crystal nuclei trees, and the best brain can grow a crystal nucleus vein. As long as there is a crystal nucleus vein, it will take more than ten years to keep the crystal nucleus and the energy source will continue to grow on its own."

Looking at Zhai Fan who was sweating profusely, "Qing Xiran" said again:

"Have you noticed that there are no children in these internal videos?"

"Why don't there be children?"

Because he was too shocked and afraid, Zhai Fan's thinking was completely led away by Qing Xiran, but he himself did not realize this.

"Because children's brains are still growing and their brain domain still has room for continued expansion, so what would you do if you were Feihua Bio? Think about it carefully."

As Qing Xiran guided her words, Zhai Fan hesitated, and the sweat on his forehead fell drop by drop. He thought for a long time before he slowly spoke up.

"I will search for good-brained children in society everywhere, raise them in captivity, find ways to expand their brains, and raise them enough to grow crystal nucleus trees, or crystal nucleus veins..."

"Very good. Have you ever heard of Xiaolongren? An institution that went to major kindergartens and primary schools before the end of the world, specializing in training for mental arithmetics in early childhood."

As Qing Xiran said this, the camera on the screen changed and some Xiaolongren's brochures and publicity posters were played, as well as the scene of Xiaolongren, Xuyou and others in the east district of Xiangcheng to rescue Shao Mengli's children.

It hits people's hearts, and there are videos and truths. Compared to talking with your mouth, the video materials "Qing Xiran" showed Zhai Fan, which completely defeated Zhai Fan's heart.

He cried, covering his eyes with his hands and bent down, and a big man who was not afraid of death actually burst into tears.

Amid his crying, "Qing Xiran" gently placed a U disk in his hand next to Zhai Fan. In the U disk, the video content of "Qing Xiran" showed Zhai Fan. She said softly:
Chapter completed!
