The script is based on the story of Xue Gang kicking the prince to death, shocking the emperor and killing all 365 members of the Xue family. Against the backdrop of Wu Zetian's "changing Tang to Zhou" and Li Xian and Li Dan wanting to restore the Tang Dynasty, the script tells the grievances and hatreds between Xue Gang and the Zhou Dynasty forces, as well as Xue Gang's complex emotional entanglements with Wu Zetian's adopted daughter Princess Jiuhuan, Ji Luanying, the daughter of the mountain chain king, and Princess Pixia of Xiliang. It also interweaves the cooperation and secret struggle between Li Xian and Li Dan, showing how Xue Gang freed himself from the contradiction between personal emotions and family destiny, as well as the responsibilities of the country and the family, and finally successfully destroyed Zhou and established Tang.
