Qin Wentian (Sheng Yilun) is born as a sickly child, and for some reason his adopted parents are forced to send him to the Bai family, who promises to give their daughter’s hand in marriage in return. The greedy Bai family eventually sets their sights on the royal Ye family, and unsuccessfully tries to back out of the marriage proposal by assassinating Qin Wentian. Qin Wentian escapes to Jiuhua Sect, and befriends his master’s daughter Mo Qingcheng (Wang Ziwen) and crown prince Yi Wuwei, who is currently in hiding.
