The Emperor of the Nine Heavens, Yang Di, once ruled the world and oppressed all races, but was betrayed by his close friends and old enemies. His soul was burned, and he was reborn with a trace of his origin, becoming an ordinary young man in the city.
After three years of dormancy, he gathered his supreme sharpness and made a living as a groom in a village in the city. He watched all the fireworks in the world, but also hid the power that could shake up the world. The blackmail of gangsters and the trivialities of life were just a passing thing for him, until an unexpected encounter gradually revealed the dormant dragon shadow.
Enemies from the past loom, and strife ensues in the world. As a mortal, he performed the duties of an emperor, pretending to be a pig and eating a tiger, just to protect the pure land in his heart and the figure that inadvertently broke into his life. When the edge is revealed again, the world is shaken, and then it is realized that the so-called ordinary is just the prelude to the emperor's hidden edge.
