Rifts into alternate spaces known as the "Ghost Realms" appear randomly around the world. Each Ghost Realm is a closed loop of rules formed from the remnants of an undiscovered extreme tragedy from the past. Anyone who stumbles inside must strictly follow the hidden rules to survive. Those who break them are erased by the realm's punishment mechanism. After Lin Yan, an ordinary librarian, is accidentally trapped in the first Ghost Realm, he discovers that he can sense the fragmentary energy left behind when a realm collapses. Relying on careful deductions, he escapes the Ghost Realms time and again while collecting fragments to compile his own Guide to the Ghost Realms. Gradually, he uncovers the human conspiracy behind their mass appearance, as well as the truth about his parents' disappearance twenty years ago.
