Eerie Cultivation: Don't Try to Out-Crazy a Psychopath

In the Great Heng Dynasty, strange phenomena ran rampant. The dynasty turned a blind eye as eerie immortals ruled over the mortal realm. Xu Chen came from another world, blessed with a Seven-Orificed Exquisite Heart. Yet all he saw were heaps of bones and grotesque, twisted monsters! As he faced the evil spirit's divine servant, Xu Chen fell into a bizarre mental chamber and had his mental illnesses extracted. Binge-eating disorder, mania, schizophrenia... I've got way too many illnesses. I don't care what kind of eerie demon or evil spirit you are. I'll fight until the sky grows dark! I, Xu Chen, am the true Spirit Immortal of this eerie world!
