The days passed, and it had been quite a short time since Yu Zecheng and Xiao Chiyo came to Mr. Shangxun's house in Birch Page.

During this period of time, Yu Zecheng is naturally studying the information of the next script every day, this script is very interesting, and the time point of its occurrence is a little earlier than before Yu Zecheng's rebirth, that is to say, in this script world, it is very likely to meet some old acquaintances before rebirth...

And Xiao Chiyo's side, she is with Wei Huang's second daughter every day, although Yu Zecheng is not an eventful person, but he can see that this time he was invited to Birch Pages Town, Mr. Xun's main purpose is to come to Xiao Chiyo, what purpose should this be, and the specific executor of the purpose is Wei Huang's second daughter. In addition, Mr. Xun gave Yu Zecheng a lot of special information for him to study, and Yu Zecheng benefited a lot during this period of time.

Soon it was time for a new script to begin. This morning, the five of them had breakfast together, and Yu Zecheng thought about it again and again, but still asked questions.

"Hmm... Can I know what happened to Chiyo during this time? I feel like she's in a better state of mind than before. Yu Zecheng rarely asked questions directly without beating around the bush, he understood that in front of an unfathomable person like Mr. Xun, it was best not to be smart, and treating each other with sincerity was the best way.

Mr. Xun said: "You can basically be regarded as the guardian of Xiao Chiyo in the future, of course, you have the greatest right to know." After speaking, he motioned to Wei Shengnan with his eyes to explain to Yu Zecheng.

Wei Shengnan put down his chopsticks and said, "During this period of time, we helped Xiao Chiyo cure a disease. ”

"......" Yu Zecheng had a headache when he heard that Xiao Chiyo was still sick: "What disease?"

"Mad cow disease. Wei Shengnan's words were concise and to the point.

"Why?!" Yu Zecheng rarely lost his temper slightly, but instantly adjusted his mood and said: "Why does Xiao Chiyo suffer from mad cow disease again? Why is it always such a strange terminal illness?"

Wei Shengnan explained: "The self-attacking disease of the immune system that Chiyo suffered from before came from his innate overly strong immune system, and the source of mad cow disease later was acquired by some factor... Speaking of which, you have also 'contributed' to this. ”

"What factors?" said Yu Ze.

"Oral immune tolerance. Taking allergens orally, in small amounts, on a regular basis, is a useful way to treat allergic reactions, except in one case. ”

"This is the kind of special disease that Chiyo suffers from that is allergic to the human body, and although oral body ingredients can cure the disease, it will also invite the punishment of nature. "Wei Sheng South Road.

"What punishment?"

"Punishment for cannibalism. Wei Shengnan said: "As a creature in nature, although human beings have surpassed other creatures and are almost free from the constraints of the food chain, in essence, human beings are still a member of the food chain. ”

"Since you are a member of the food chain, you are naturally bound by the food chain. In the food chain of nature, the behavior of all organisms is to reproduce, that is, if an abnormal behavior of an organism runs counter to the general principle of reproduction and reproduction, then nature will use some extreme methods to correct this abnormal behavior, or even eliminate this creature. ”

Wei Shengnan explained this, and Yu Zecheng had completely understood.

The best way for an organism to reproduce and survive is to promote its own evolution, so that it can obtain more resources for reproduction, which is the "right way" prescribed by nature for organisms.

Cannibalism, on the other hand, is contrary to the main purpose of reproduction and evolution. If an organism uses the same kind as food, although it can allow one or two individuals to obtain survival resources in the short term, but when it is magnified to the reproduction level of a population, this kind of eating the same kind of behavior is a very inefficient or even negative efficiency method, not only can not increase the number of populations, but will accelerate the rate of population extinction.

But there is a paradox, although eating the same kind is not conducive to population reproduction, but for animals, the same kind is the best "hunting" object, their own habits and characteristics of the same kind are not only well understood, but also can accurately judge the same kind and their own combat effectiveness, and can even calculate the time for the same kind of rest to launch a sneak attack...

Therefore, in order to prevent this phenomenon of hunting each other within the population, the miraculous nature has given all the higher species an insurance, and this insurance is mad cow disease.

If there were no large numbers of cannibalism, the disease would never have appeared, but if there was a large number of cannibalism, the disease would have come as a nightmare as a punishment of nature.

Historically, the cause of mad cow disease in Europe was that some farms used very cheap cattle bones and cow offal (foreigners rarely eat offal, so it is cheap) to grind and mix with feed to supplement the cattle in the farm with protein and calcium. This inadvertently contributed to the conditions of cannibalism, which led to mad cow disease.

In fact, cannibalism is theoretically okay, just don't eat the brain, because disease-causing prions are present in large numbers in the brain, and there are basically no other parts of the body. But no one can guarantee that you will be fine if you only eat your body, after all, no one can tell how many biological codes and traps are contained in such a delicate and complex masterpiece of nature.

Therefore, in the script of "Loving Heart", although Chiyo's extreme allergy was cured by eating the body of his relatives, it also inevitably ingested a large amount of human body ingredients, so the seeds of mad cow disease were planted in Chiyo's body...

Yu Zecheng thought for a moment and asked, "If I hadn't chosen to use the 'Delusional Paranoid Girl' skill card to bring Chiyo back to reality, wouldn't she have died of mad cow disease in the end?"

Mr. Xun smiled: "I think it doesn't matter, the law of evolution of living things is to eliminate those individuals who are not suitable for survival, but Xiaobo doesn't agree...", he said and gestured to Huang Yanbo next to him with the corner of his mouth, "Xiaobo This guy and I are not exactly the same thinking, even if you don't pull Xiao Chiyo to reality, Xiao Bo will personally go to the parallel universe of "Loving Heart" to treat Xiao Chiyo, after all, that universe is completely our originality..."

Mr. Xun stopped here and made a conscious expression, but Yu Zecheng understood that this was for himself to see, and it was deliberately revealed information, and it would take time for him to understand it in more detail.

......

In the afternoon, it was time to enter the world of the script, Yu Zecheng calmly sat on the sofa and chatted with Mr. Xun, Xiao Chiyo sat in Huang Yanbo's arms obediently, holding Wei Shengnan's hand, although he made up his mind, but in the face of unknown things, Xiao Chiyo was still very nervous.

The familiar diamond-shaped light appeared, and Yu Zecheng once again entered the world of the script, only this time he was not alone, and there was a small chiyo who needed to take care of him.

His eyes began to blur, and after a few CG scenes, Yu Zecheng regained control of his body.

！！

After being reborn this time, Yu Zecheng was very surprised. First of all, the background of this rebirth is the beginning of 1944, the era when World War II was about to end, but this is not a point of surprise, Yu Zecheng was surprised that he found that his body had not changed after being reborn, it was Yu Zecheng's own body!

Secondly, Yu Zecheng found that Xiao Chiyo was not by his side.

Could it be that in this script, he and Chiyo have different tasks?

Just as Yu Zecheng was thinking about these questions, a prompt appeared in the task screen in his mind.

Main Quest: Extinction of Japan.

Side Quest: Find Chiyo Ko.
