The most desperate thing in the world is not a miserable life, but a clear desire to die, but having to shoulder a heavier burden and continue to face it.

With the extension task "Make Your Choice" in his mind being marked with a green tick, Yu Senmin's suffering is over, but Yu Zecheng's suffering has just begun.

With the end of this flashback plot, all the memories of Yusen Wanli poured into Yu Zecheng's mind...

The ins and outs of the whole thing and the details fill in the framework that has been sorted out at the rest of the cost, and the truth of this "Loving Heart" script is completely restored.

Chiyo was originally a healthy little girl, but she suddenly contracted that unknown disease at the age of three, and then her condition began to deteriorate, and finally she became severely allergic to herself, triggering her immune system to attack her own tissues and organs, all for a reason.

The human body itself is a relatively perfect internal circulation, and this internal circulation can run smoothly and maintain its own health under the attack of various strange bacteria and viruses in nature, thanks to its own strong immune function, and the immune system with continuous logistical support is like an unbreakable computer firewall guarding our body.

But this is a paradox, because in a way, the firewall is the biggest virus.

The same is true of the immune system, which is very difficult to treat, and the difficulty in treating it is not that the immune system is not inadequate, but that the immune system is not able to function properly.

Just like cancer, those cancer cells are really the fluorescence of rotten grass for the immune system, compared to the bright moon in the sky, the immune system can crush all cancer cells casually, but the key to the problem is not this, but the immune system can not perfectly recognize all cancer cells, which is the reason why cancer cells always resurge, and at the same time, in the process of catching mice and cats with the immune system, cancer cells will continue to evolve themselves, and when cancer cells can be completely confused, cancer will begin to deteriorate and metastasize.

It's better if the immune system can't distinguish between the enemy, but if the immune system doesn't distinguish between its own people... That will target normal food or other foreign organs transplanted into oneself and attack itself, which is the truth of allergic reactions and rejection reactions in the human body.

And Chiyo's immune system has happened to be arguably the worst situation in history, because Chiyo's immune system recognizes the human body as an attack, as long as Chiyo is close to someone, the immune system will attack, even if Chiyo is isolated, her immune system will still target her own tissues and organs, and continue to carry out endless self-attacks...

The facts of nature continue to expound a truth, and the most difficult thing for man to overcome is himself.

Lao Tzu said: Those who know others are wise, and those who know themselves are clear.

The reason why Chiyo suffers from this extreme self-allergy is that after Chiyo was born, Mr. and Mrs. Yumori loved Chiyo too much, so they had too close contact with Chiyo in their daily life and when they slept. ”

Actually, this is not a big deal, but Kochiyo is a person with an abnormally developed immune system.

There is a process and law for the immune system to recognize enemies and friends, and this law can be summarized as follows: as long as the intestines are exposed to foreign objects first, then the foreign objects will pass the self-test of the immune system, and if the foreign substances are contacted by the skin or other organs before the intestinal and other digestive systems come into contact, then the probability of the foreign object being recognized as an enemy by the immune system will be greatly increased.

This is easy to understand, because people always have to eat, and food must be foreign to the human body, so in order to prevent the immune system from attacking food and intestines, the digestive system has the function of helping foreign substances that enter it to pass the strict inspection of the immune system.

For example, if a child has not eaten pasta after birth, but for some reason the skin or nasal passages are exposed to flour, then the child's allergy to flour and pasta will be greatly increased. The immune system is not intelligent enough, they mechanically think that what enters the human body from the mouth is the friend, and what enters the human body from other organs is the enemy, and the more developed a person's immune system, the more likely it is to develop allergies due to the above reasons. This is also the reason why scientific parenting advocates adding complementary foods to babies as early as possible.

Chiyo's unusually developed immune system is the root of all this tragedy, in infancy due to too frequent close contact with parents, which leads the immune system to think that the human body that comes into contact with organs such as skin and nasal cavity is a foreign body, an enemy, and then launched an attack, because the constitution is inherited from the Yumori couple, so Chiyo's own organ tissue is also included in the attack list...

The skin is constantly festering, the organs are constantly bleeding internally, and the whole body is collapsing...

So, after understanding all this through research, the Yumori couple put all their energy into how to alleviate Chiyo's severe allergies, but with the two of them fighting against the complex and sophisticated human body and Chiyo's incredible immune system, the amount of work was too large, and Chiyo's illness could not be delayed.

It is easy to know the sky, but it is difficult to go against the sky. Many times you know the root of all the problems, but you are powerless, this is a very fucky logic, but this logic appears in our lives all the time, otaku who compromise with reality, staff who have the ability but can't shoot horses, generals who are powerless on the battlefield, politicians who want to change the system but can only keep themselves clean...

Oral immune tolerance. Reality left the Yumori couple with only this one way, a path of self-sacrifice.

This is the stupidest way to treat allergies, since the digestive system is the only legal passage into the human body, then through a small number and multiple oral allergens, the body slowly adapts to the allergen, so that through the immune system's self-test, eventually to a large extent to weaken or even eliminate the allergic reaction.

To put it simply, you are allergic to peanuts and eat peanuts, and you are allergic to milk and drink milk.

Then you have to eat people.

So Mr. and Mrs. Yumori obtained some human tissue through their duties, processed it into capsules containing human tissue protein through a pharmaceutical machine in the basement of their home, and then carefully controlled the dose and fed it to Chiyo, so that Chiyo could slowly adapt to the human body.

Soon, Chiyo-chan's condition improved, her body adapted to human tissue proteins, and she was no longer allergic to strangers.

But this is far from completely curing Chiyo, Kochiyo is still allergic to the Yumori couple and herself, and the immune system's attack on herself continues, if you want to continue the treatment, you can't let Chiyo eat herself, right?

Of course, it is impossible to eat yourself, but it is possible to eat grandparents and blood relatives who are very close to your own physique and bloodline.

The closer the blood relationship, the closer you are to completely curing Kochiyo...

So three years ago, Tom Yumori's parents and Mr. and Mrs. Akagi chose to kill themselves in order to treat their only blood relatives, Kochiyo, and then their bodies were made into special capsules by Mr. and Mrs. Yumori, and after starting to take this capsule, Chiyo's condition was further improved.

But it's not enough, more allergens need to be taken orally in order to control Chiyo's allergies within a survivable range.

The next self-sacrificial person is the great mother who is willing to go to the soup for the sake of her children, Yu Senmin.

After Yu Sen's death, the body was crushed and dusted, and it was crushed and processed into a special medicine that could treat Chiyo-chan.

Although Yu Senmin died, the love for his daughter remained, and it turned into a special effect capsule, along with Yu Senmin's body fragrance was put into the safe, and slowly turned into his daughter's flesh and blood in a year...

The only thing that remains in the world now is the right eye that allows Yu Mori to unlock all the research permissions he had before his death.

Yu Senmin's sacrifice lasted another year, and if Yu Sen Wanli couldn't find another cure within a year, then who would be the last victim next, the answer was self-evident.

……

This is the whole story, after figuring out all these situations, on the task screen in Yu Zecheng's mind, the main quest "struggle" was marked with a green tick, and at the same time, Yu Zecheng's emotions fell into an unprecedented struggle!
