A mountain doctor is a fortune teller

He was talking about an orphan who was studying taoism. After he died unexpectedly, his soul went to Ying chau, and he returned to the real world after learning the orthodox heavenly book spell from the immortal in Ying chau. After he woke up, he had the ability to subdue demons and eliminate ghosts, from immature to mature, and when he realized that his ability was not recognized by modern times, how should he choose? The more he walked back, the more he finally understood that it was not a ghost but a human heart that was scary.
