Qingshan Mental Hospital Explodes

The world's most dangerous mental hospital and their only director instantly create a subversive perception. Ten years ago, global supernatural powers went out of control, and the seven most dangerous S-level berserkers were secretly imprisoned here. Ten years later, this Qingshan Mental Hospital remains calm, until... the gentle director who measures blood pressure and dispenses pills to patients every day gently pushes his glasses. 'Ten years,' he says mildly to the seven 'patients' behind him. 'Time to go out and get some fresh air.'
