There are seven different areas in the underworld, namely the black area, the white area, the red area, the blue area, the blue area, the gray area, and the purple area. The black domain is the highest level and is where the central government is located, followed by the white domain. The other five domains are all the residences of people of low blood, and there is little differentiation in power. For thousands of years, there has been a very strange rule in the underworld, that is, only princes with silver-white hair can inherit the throne of the God of Death. Among the princes born in the seventh generation, only the sixth prince, Xie Zhi, has white hair. But everyone is confused that his hair is only pure white, which makes the eldest prince eager to spy on the throne of the God of Death. Among the new maids, there was a girl who looked like Baozhu Yuxi, the princess-to-be of Xiezhi. Under the deliberate arrangement of the eldest prince, she became Xiezhi's maid. During the long-term relationship, Xiezhi fell in love with this maid and wanted to give up Baozhu Yuxi of the Baiyu tribe, which made the seventh generation furious, and sent everyone around Xiezhi into the human world to suffer the sin of reincarnation. Xie Zhi in the human world was kind and gentle, and liked a comfortable life. They lived a small life of fighting and fighting together until one day a woman named Wu Heng appeared. From then on, hell and the world became one. The eldest prince rebelled and was killed in the underworld, and her next target was Xie Zhi. The women who were thrown into the human world together with Xie Zhi died at the hands of Wu Heng to protect him. In the end, Xie Zhi accepted the fate of death and suffered the pain of memories in the underworld.
