Supernatural: My Family's Ancestral Yin-Yang Business

On the Ghost Festival, my grandfather suddenly emerged from the grave and told me that my family is an ancestral Yin and Yang merchant, and all ghosts traveling from the underworld to the Yang world must obtain my approval. Think about it, be polite and take the money! No money? Where did you come from and where are you going? When I have had enough fun and no longer want to live, I can travel to the underworld like him. This novel and its characters are purely fictitious.
