Welcome to the Endless Library - a huge archive and colosseum that exists in the dimensional rift and contains the knowledge of all worlds and anomalous individuals.
Chen Mo wakes up here, and his memory becomes a mystery. The rules of survival are cruel and simple: borrow every day, pay the price, otherwise you will be "cleaned". He and his companions are forced to struggle to survive among bookshelves full of deadly rules and mysterious entries.
However, they soon discovered that behind the so-called "game" was a game between a cold observer named "Chengdian" and an even more ancient "god" who regarded all living beings as pawns.
From the abyss of the library to the "threshold" with chaotic rules, Chen Mo holds a silver pocket watch in his hand and carries the forbidden plan of "Ouroboros". While pursuing freedom, he gradually uncovers a huge conspiracy that is closely related to himself and can subvert reality.
