Rain Before is very famous, very, very famous. There is no other reason, just because he is the only male Meng Po in the history of the underworld. Therefore, he repeatedly emphasized that "Meng Po" was just his position and everyone had to call him by his real name - "Yuqian".
Except when the souls left their previous lives and stepped onto the Naihe Bridge and were about to leave the underworld, he hated others calling him "Meng Po". If any of his colleagues or acquaintances, demons, ghosts, gods, humans or animals, at any other time, intentionally or unintentionally, as long as someone calls him "Meng Po", he will immediately give him a knife. It's really an eyesore. Although it is not stuck on the body, this "knife" is enough to immobilize all living creatures, and then they will be fed a bowl of "Meng Po Soup" before their eyes.
One day, a strange thing happened on the 19th level of the underworld. The result of this incident made everyone in the underworld worried. If not for anything else, it's because the position of "Meng Po" is likely to have no successor. As a last resort, Yuqian had no choice but to take the four little ghosts, Demons and Demons, on a journey to find the next "Meng Po".
