In this world, there are two major races - humans, night ghosts and Tianxuan (also known as the Sun-eating Tengu). They are different tribes of the same race. Their main contradiction is reflected in their struggle for the throne of God. The background of the story is that the Sun-devouring Tengu race has inherited the throne of gods for centuries. The evolutionary path they led was found to be in danger of extinction if it continued. Humanity and the Chosen jointly cut off the previous generation of gods. The gods of the previous generation were killed, the throne of gods fell aside, and the night ghost race was severely damaged. The two major races established a balanced balance order in fear of each other (the night ghosts are at the lowest level).
Xu Mo left Qingjing City when he was fifteen years old. Unable to tolerate his memory defects, he wandered around Qingjing City while performing the Chosen Mission. Finally, in an encounter with a night ghost, he was mistaken by the "Light Gap" agency of the human camp for a fallen night ghost who was extremely dangerous and disqualified from the human world. At that moment, the gears of his destiny intertwined with other lives and began to rotate completely.
