I'm Interrogating the Murderer in the Copy

When Chen Zhihui woke up, there was a mental hospital wristband on his wrist. Medical records showed that he had been admitted to the hospital three days ago, but his memory stopped at last night. Midnight ward rounds, faceless nurses, missing patients, and tampered death files appeared one after another. Others just wanted to leave the dungeon alive, but he discovered that the key to clearing the level was not to escape, but to find out the hidden murderer.
