The plot of "Heaven Sword and Dragon Saber" by Zhang Jizhong tells the story that at the end of Yuan Dynasty, Zhang Cuishan, a disciple of Wudang, and Yin Susu, the daughter of the Lord of Tiangeng Sect were involved in the dispute over the ownership of the Dragon Saber. Together with Xie Xun, the Lion King with Golden Hair, they drifted to an uninhabited island in the sea. Zhang and Yin got married and had a son named Wuji. Ten years later, Zhang Cuishan returned to Central China with his wife. However, because of their connection with the Dragon Saber, they were forced to commit suicide, leaving behind only an orphan, Zhang Wuji.
