I'm Undercover in the Fierce Ghost Chat Group

Ning Yan traveled through the parallel world and became an employee of a funeral home. During an ordinary corpse-moving job, the Yin-Yang undercover system was awakened, and he was pulled into a ghost chat room. Fierce ghosts: "Boss Ning Yan, they say you are a spy sent by the underworld. Is this true?" Ning Yan: "Have you ever seen an underworld spy who killed a ghost?" Underworld: "Ning Yan, although you helped the underworld capture countless ghosts, it is said that you also worked with them to plot rebellion. Is this true?" Ning Yan: "Since I am said to be treasonous, then from today onwards, the Ten Palaces of Yama will be replaced!" Three years and three years passed, and Ning Yan didn't know why he was an undercover agent and later became more vicious than the King of Hell! This novel and its characters are purely fictitious.
