On the surface, it is a modern city (Yunhai City) where materialism prevails, but secretly it hides an ancient martial arts family and a secret inheritance. In the outskirts of Yunhai City, at the bottom of the "Burial God Abyss", a forbidden area where no one can approach, there lives a group of "Thirteen Ghosts" who are hiding from secular vendettas. They master the lost ancient martial arts and mysterious medical skills. The wealth and order of modern society are actually controlled by these plutocrats and the forces of the dark world who wield extraordinary force.
