There exists a certain type of person in the world:... more>>

Their eyes see no colors, only black and white; they hold no hope for the world, only despair; they lack the will to live, accustomed to curling up in the shadows of darkness.

As part of a newly developed batch of caretaker systems designed to help such patients rekindle their love for the world, System 2020 is very enthusiastic about its work. It has even studied numerous cases from its predecessor systems, such as: "How to Save Autism Patients," "Counseling and Guiding Dark Criminal Minds," "Making the Wolf Fall in Love with the Lamb," and many more.

Then it met its first host.

System 2020: Mama, I met an angel ⊙ω⊙!

After traveling through many worlds, its host would comfort the system, which was often doubting its purpose.

Host: It's okay, I feel fine ^_^

System 2020: QAQ *sobs*

Host: Really, except for sometimes having to block knives, bullets, and hidden weapons for others, sometimes not being able to get out of bed for a month, sometimes waking up locked in a dark room, sometimes... everything else is fine ^_^

System 2020: o(╥﹏╥)o !!!!

The author has a wild imagination and might introduce unexpected plot twists from time to time. If you're not comfortable with this, please avoid reading.

In the third world, both the top (攻, gong) and bottom (受, shou) are animals. Although they will eventually transform into humans, and there won't be any explicit beast-related scenes, if this bothers you, please do not continue. <<less

Wen Xin had an emotional disorder since childhood. On his doctor’s advice, he began keeping pets. One torrential rainy night, he picked up an injured little black furball and brought it home.... more>>

The black furball was extremely aloof—it refused to eat pet food, wouldn’t let him hold it, and its body would occasionally mutate, emitting low groans of pain.

But Wen Xin didn’t find anything amiss. He put effort into creating recipes for the furball and, when it was in pain, he would hold it in his arms, gently patting and soothing it.

Later, more and more furballs appeared in Wen Xin’s home, each with its own ferocity. Even the aloof black furball began to rebel, taking advantage of his inattention to violently beat up the other furballs.

Wen Xin was so tormented that he no longer had time to feel down.

After finally getting through the difficult adjustment period, before Wen Xin could enjoy a few days of cuddling with the furballs, the apocalypse broke out.

He and the furballs were accidentally separated. He joined a large group heading to a survival base, where he heard that top-level mutants were appearing all over the place.

They were powerful enough to dominate territories as kings, so ferocious they made people tremble—yet they were all frantically searching the world for one human.

That human was named Wen Xin.

Gold, silver, wealth, fame, power—anyone who could help them find “Wen Xin” would be treated as an honored guest by the mutants.

Struggling humanity seemed to see a ray of hope; all at once, the entire world set off a frenzy to search for “Wen Xin”! <<less
