Weird World: the Day I Worked for the Underworld

This world is never black and white, but a delicate gray. Young Li Feng encounters a ghost. At the last moment of his life, Li Feng signs a labor contract with the underworld. He pawned all his lifespan to Yama in exchange for a chance to be reborn. From then on, Li Feng began to work illegally for the underworld. From then on, it was terrible, sitting in the arms of Black and White and impermanence, and stepping on the feet of Yama's lovely wife. Ahem… Of course, this is all Li Feng's imagination. The door to the world of cultivating supernatural powers has officially opened, including humans, ghosts, demons, gods, and charms... Someone stands in the spotlight, accompanied by thousands of people, and he says that he is justice. There was a ghost sobbing in the mass grave. She said she had been waiting for someone for a long time. There is a demon building a human race's capital, seeking eternal life in the void. There is a god high in the sky, looking down at the world with cold eyes. And Li Feng, who just wanted to eat hot pot and hug the school beauty, was forced to get involved in a series of strange events. What is this world like?
