After attending the team's celebration banquet, game text planner Lin Qingliu stumbled upon another world by sheer luck:

Meteorite? What meteorite?

What do you mean by "humanity is left with only one city and the outside world is full of strange beasts"?

Before he could figure out what was going on, Mr. Lin discovered that the USB drive that had traveled with him had become his cheat system, and the discarded design drafts stored on it seemed to be having a strange collision with this world...

"Huh? I've become a god? Really...?"

Is it really possible to gain great power simply by cultivating followers? Is there such a good thing as harvesting韭菜 (a metaphor for exploiting followers)?

In a world on the verge of destruction, a self-made god-in-training chooses to embark on the path to godhood, and incidentally saves this somewhat absurd world.

But before that... even the gods need to mend their own roofs...

A story of a "trinity" of a god, a preacher, and a paperhanger...

"As for those legends of exploration teams, secret police leaders, great inventors, and shadow godfathers of the outer city, what do they have to do with an ordinary psychiatrist like me?"

(Author's notes: 1. The characters have relatively even screen time, so those who are sensitive to ensemble casts should proceed with caution. 2. The story is generally lighthearted, and the protagonist is incredibly human... 3. There will be some imaginative and modified short stories; treat them as side stories. 4. If you find any issues with the world-building... perhaps you should read on?)
