I Joined the Underworld Chat Group and Made All the Ghosts Cry

Yun Tian was inexplicably dragged into the chat group of the Underworld. From then on, his life was all about messing with ghosts, or on his way to mess with ghosts. Do these ghosts seriously come up with their names themselves? In charge of... Bao Someone, the Woman-Avoiding City King, and the Can't-Swim Mount Tai King. And what about the Minister of Justice? Are they serious about all these names?
