The Taoist priest came down from the mountain with nothing but an old inkstone, a bald brush, and a purple gold gourd filled with wine. Yu Chen is the most talented person in the Taoist generation, but he is not very serious - he can lie down but not sit down, and he can drink wine but not tea. The master thought he was either sleeping or drinking all day long, so he kicked him down the mountain to travel around the world, and asked him to find his senior brother Lin Yuan who was driven down the mountain three years ago. When the senior brother found him, before he could reminisce about old times, he received a strange incident: the old man of the Zhao family in Zhendong was having a funeral, and the coffin could not be lifted. A series of unbelievable and strange things happened one after another: a family of four slept on the ground every night in a newly built villa, three girls disappeared one after another in an old residential building, and finger bones that had been buried for hundreds of years were hidden in an unknown cave in the mountains. As he solves cases and catches ghosts along the way, he gathers more and more people around him - the mature and sultry senior brother Lin Yuan, the neat and tidy police captain Tie Xinlan, the gentle and reserved Su Wanqing, the young monk Jing Kong who accepts death, and a white fox of unknown origin. People walk in the mortal world, and ghosts walk in the dark.
