The Worm Calls the Watchman

There is an inn next to the Naihe Bridge, named Naihe Inn. The innkeeper is Wangchuan, the lord of the Wangchuan River. Because he was tricked by the Lord of the Underworld and lost the bet, he promised to deal with the ghosts who escaped from the underworld. These ghosts are just cannon fodder. Behind the scenes is the extremely ambitious Ghost King. Humans have a life span, and ghosts also have a ghost life span. Even those who are as powerful as ghost kings can only live for 600 ghosts, so these ghost kings reach out to the world, but the yang energy in the world is too strong and they can no longer walk directly. They can only control the lonely wild ghosts to turn into insects, find a suitable living person to seize the body, and then use living people to practice to achieve immortality. But this goes against the order of reincarnation in the world and the imbalance of insect reincarnation in the book of life and death, so the Lord of the Underworld went to Wangchuan and asked Wangchuan to use the power of Wangchuan River to deal with these obsessions of seeking immortality.
