Pei Zhaoxuan, a modern-day office worker, travels through time and becomes the new emperor of Great Yu. He is bound to Tuan Tuan, a little fortune spirit who disperses his imperial fortune. By consuming imperial fortune, he can gain cultivation power, and once his imperial fortune reaches zero, he can ascend to immortality. Yet crises abound both inside and outside the court. Prince Jing, Pei Zhaoheng, watches him covetously, while Northern Yin forces Great Yu to cede territory and pay reparations. Refusing to play by the rules, Pei Zhaoxuan cleverly puts He Chongshan, Qin Zhaoye, Shen Qianzhou, and others to use. Through court intrigue and border conflicts, he repeatedly turns the tables, crushes Prince Jing's conspiracy to usurp the throne, and ultimately safeguards his country and people before choosing to live out his life in the present world.
