When Lin Mo's roommate Zhao Yang fell into a coma due to a mysterious red-covered book, all ordinary college life came to an abrupt end.
In order to save his friend, Lin Mo stepped into the unknown "Midnight Library" on campus - a mysterious place that is only open at midnight and has thirteen strange borrowing rules.
"Don't look back down the hallway."
"If you hear someone calling your name, don't respond."
"If you see a girl wearing red glasses, close your eyes and leave the current area immediately."
There is a terrible price hidden behind every rule, and every borrowing is a game with unknown forces.
As Lin Mo gradually uncovered the secrets of the library, he discovered that it was not only a treasure house of knowledge, but also a huge trap that preyed on human curiosity. And is that mysterious librarian a protector or a prison warden?
In the maze of knowledge and price, Lin Mo must find a way to break the rules, not only to save his friends, but also to reveal the truth and liberate all souls bound by the rules.
Midnight Library never owes anything, but it evolves. When the bell rings, do you dare to push open that door?
