In this wasteland world ruled by monsters and steel, humans are sheep, androids are sheepdogs, and fear is the wool that must be turned in every day.
In order to prevent logic from crashing, the androids stuffed low-level humans into extraction chairs and forcibly extracted the "source essence" secreted under extreme fear. Here, only the strong who burned out their nerve [marks] when they were about to die deserved the right to breathe.
Ji Lin is a low-level scavenger who doesn't even have a file. In order to prevent his sister from being drained as a "biological battery", he was forced to hold double blades and became a low-level "hound" who specializes in dealing with monsters. Relying on the lowest-grade defective discarded chips, Ji Lin transformed from a wild dog in the sewers into a midnight scavenger who made the entire underground black network fearful. Struggling to survive in desperate situations.
Until one day, he discovered that the monsters wandering the wasteland, the androids ruling the city, and the meaning of the world's existence all seemed to hide the same secret.
And that secret. Enough to subvert the entire human civilization.
Nice! Like! Wonderful!
