Li Shuai delivers a mysterious package to the Wang family’s skyscraper, one of the four great clans, and accidentally saves the Wang family’s jinxed daughter before marrying into the family. He thinks he is about to die on his wedding night, but his memories from three lifetimes and ten thousand years of magical power return. His mortal body cannot handle them, however, and after a brief bout of amnesia, he earns the old matriarch’s disdain. Once an ancient medical text fuses with him, his body is strengthened and he regains his ten thousand years of magical power, but he is bound by a three-year contract as the Wang family’s live-in son-in-law. This world seems peaceful, harmonious, and beautiful, but among the people is a group that guards the boundary between Blue Star and the Dark Dimension, slaying demons and monsters to protect Xia Kingdom’s peace. They are the Nightwalking Red Gate. When the Demon Emperor of the Dark Dimension returns to Blue Star, the gods who protect the nations of the world also return. Odin, Father of the Gods; Uranus, King of the Gods; Brahma and Atum, gods of creation; and Pangu, the creator god of China: a creation war among gods, humans, demons, and monsters begins without warning, and the universe turns a new page.
