Psychiatric Hospital: I Slay Ghosts with Physical Force

The paranormal has returned, and rule-based horror dungeons are sweeping across the city. Lin Chen, a master's graduate in theoretical physics, is inexplicably locked away in an asylum plagued by strange events, with a Key System bound to him. When others encounter ghosts, they can only burn incense, draw talismans, and flee in terror. He alone carries batteries and modifies all kinds of devices, using the laws of real-world physics to blast every kind of evil spirit head-on. The asylum is full of ever-stranger horrors. Every time he kills one, he unlocks new, advanced knowledge of physics. The world fears ghosts and gods. I believe only in the conservation laws of physics. I'll use physics to slay ghosts and gods, and never stop!
