Hou happy was diagnosed with "hereditary delusional disorder" since he was a child. He sees strange things that ordinary people don't see: human-faced bugs squirming in the cracks of the wall, black shadows walking backwards in the mirror, and a tongueless old woman knocking on the door late at night. The medicine allows him to live in a numb "reality", and when he stops taking it, he falls into the "realm of skeletons" where monsters and monsters are rampant - where the sky is a huge pupil, the earth is covered with vein-like ravines, and practitioners use their own bones as containers to refine ghosts into "skeleton pills", and the avenue is the reflection of madness.
When the real-life psychiatrist becomes the "soul-eating doctor" of the skeletal world, and when the patients in the ward turn into "skeleton slaves" seeking their lives, Hou Xi discovers that the so-called "delusions" are actually the reverberations of ancient mystical ways, and his "disease" is the "body of skeletal remains" that can connect the two worlds. He must choose between the sanity maintained by drugs and the power given by weirdness. While resisting the shackles of "treatment" in the real world, he also deals with cannibal monks, deformed monsters, and sanctimonious pseudo-fairies in the skeletal world to find the truth about the imbalance between the two worlds and his innate "madness destiny."
