On their wedding night, Ye Xuan, the former fourth prince of the Tianfeng Empire, became a son-in-law. He was publicly humiliated by Changle Princess Mu Qinghan and forced to sign a divorce letter. When he couldn't bear it any longer, he awakened to the ancient times to devour the holy body, burned the divorce letter and swore an oath: to wash away his humiliation, divorce his wife, and seize the kingdom!
The former good-for-nothing son-in-law secretly devoured spiritual power and quickly rose to prominence. He slapped the dignitaries in the face, hunted and shocked everyone, and defeated powerful enemies on the border. From contempt to regret, Mu Qinghan fell in love with her husband every step of the way, and summoned him for defying his father and risking his life.
Revealing the truth about the murder of his mother and concubine, and confronting the sect's villains, Ye Xuan used his iron-blooded tactics to defeat both the government and the opposition. At the enthronement ceremony, he tore up the old divorce letter and took the princess's hand: "The country is mine, and so are you." This is an emperor's legend of a son-in-law's counterattack and love and hate!
