Zhao Huan transmigrates into the body of the last emperor, just as he is about to ascend the throne. But on that very day, Regent Jiang Heng and the Empress Dowager join forces to depose him and throw him into the imperial prison. At this desperate moment, he pulls 108 edicts of annihilation left by the dynasty’s founder from a hidden compartment in his dragon robe. Each one is enough to wipe a powerful clan off the map. Using the edicts, Zhao Huan escapes and allies himself with Jiang Wantang, who is disguised as a spoiled playboy. He also wins over the common-born censor Gu Qingci, the shadow guard Su Tan'er, and Zhou Yuanlang, son of a general seeking revenge, gradually dismantling Jiang Heng’s network of power. But a mysterious secret decree that contradicts the edicts comes to light, revealing an even deeper conspiracy behind the upheaval of imperial power.
