To be more specific, it can be understood as a unit story similar to "The Heavenly Master Takes the Throne". In short, it is the story of these two... Retired immortal king and the current ghost master going to the human world to make trouble (laughs). Please believe that this is indeed a BL novel, but the element of danmei is not so obvious at the beginning...
Please rest assured that this story is by no means a trap, because the entire text has been written, and will be updated slowly.
