Fan Xian is born in the ancient empire of Southern Qing with memories of the 21st century. He is raised by his grandmother in the rural town, Danzhou as the illegitimate son of the Minister of Finance. His mother, Ye Qingmei was once a celebrated inventor who founded the Overwatch Council, the country's spy network and the Royal Treasury but was killed shortly after her son was born. Fan Xian has been protected since birth by a blind martial arts expert, Wu Zhu, his mother's bodyguard. He learns martial arts and the art of poison as a child, also assisted by his knowledge from the 21st century. After an assassination attempt, he decides to venture into the capital to find out more about his mysterious mother and why anyone would want to kill him, as he perceives himself to be an unimportant person. He also wants to know why he has memories of an obviously different era. In the capital, he accidentally meets Lin Wan'er, the sickly illegitimate daughter of the Princess Royal and falls in love with her. Unbeknownst to him, she is the woman the Emperor chose for him to marry so that he could take over the Royal Treasury, an institute Fan Xian's mother established in the palace and currently handled by the Princess Royal. In the capital, however, he gets entangled in the relationship between the Emperor and the two Princes, as well as the Overwatch Council, leading to him question his whole identity and motivating him to find his true life goals, abandoning his original intention to just "enjoy life".
In the 46th (and final episode of season 1) Fan Xian, choosing loyalty to friends and family over loyalty to state, is apparently killed. Two more seasons are planned.[8]
