On the third day after Shen Ci was imprisoned in the mental hospital, he discovered that the patients were missing one after another. In Room 404 at the end of the corridor, the sound of nails scraping against the wall could be heard every midnight. Last night, the shadow of the nurse on duty turned into a monster with three arms.
No one believed him. Everyone said he was crazy.
But Shen Ci knew that he was awake - because he could see these things that normal people could not see. He is not a patient, he is a "drug experimental subject" who was sent in, code-named: Zero.
Under the hospital, there is a being sealed that even the evil god would kowtow to. The seal is breaking and it's hungry.
A greater disaster is brewing. There are four words written on Shen Ci's medical record - "Voluntary Check-in". Deep in the spirit, a voice whispered: Mortal, are you willing to be my knife?
