There is a century-old library in the old town of Haicheng that is about to be abandoned, and strange stories about it have been circulating for a long time. Every time after the library closes at midnight, there will always be sounds of turning books, footsteps, and book return slips appearing inexplicably on the borrowing desk. Lin Wu was forced by life to take the job of night shift administrator. He thought he would just stay up late guarding an old building. Unexpectedly, he bumped into the ghost who only appeared on the surveillance camera on the first night.
What's even more terrifying is that the ghost's face is exactly the same as mine.
As the investigation deepens, Lin Wu discovers that there is a batch of banned books hidden in the library that have never been made public. The books record not knowledge, but erased lives, folded time, and a disappearance case that lasted for ten years. Ten years ago, a young man borrowed a book that should not have been opened and disappeared from the world. And all the evidence points to a ridiculous and chilling answer - the missing person is none other than Lin Wu from another time.
In order to find out the truth, Lin Wu had to travel between reality and book pages, tracing the secrets of past administrators of the library, the origin of the catalog of banned books, and the ghost of the director who always sat in the deepest reading room and refused to leave. With each layer of mystery solved, Lin Wu gets closer to the truth and closer to the fate of being swallowed up by the library.
But when he finally understood why the ghost became himself, he discovered that what this library really collected was never books, but people's fate.
