The Shadow World is a separate world that exists outside the ordinary world. That world had a strict system, a strict hierarchy, a distinction between high and low, and power was supreme. There are four different ethnic groups living there, they are the blond royal family, blue-haired nobles, red-haired middle people, and brown-haired flat people. Under these four ethnic groups, there is also a special ethnic group: the black-haired inferior race.
The black-haired inferior race is a lowly ethnic group that has no identity certification in the shadow world and is not recognized by the shadow world. They live in the poor and dirty Dongcheng District, doing the most menial jobs and receiving the lowest wages. They are the shame of the shadow world, a dirty race that everyone in the shadow world avoids.
Cang Yan, the highest-ranking blond royal family in the Shadow Realm, has a distinguished status, but has an extremely bad character. He enjoys playing with others and seeing others suffer is the source of his life's fun.
Qingcheng, the lowest black-haired inferior race person in the shadow world, has no connection with the blond royal family, but he was attracted by Cang Yan because of a few insignificant Ganoderma lucidum fruits, and was forced to sign a three-year bet. From then on, he has been tied to Cang Yan for life.
