At the end of the Southern Song Dynasty, the Red-Filmed Fairy Li Mochou (played by Meng Guangmei) went to the south of the Yangtze River to seek revenge on her former lover Lu Zhanyuan (played by Hu Dong). When the great hero Guo Jing (played by Wang Luoyong) and his wife Huang Rong (played by Kong Lin) were helping Lu Zhanyuan's family, they discovered that the beggar boy Yang Guo (played by Dingdang) was the son of his sworn brother Yang Kang, so they took him back to Peach Blossom Island and sent him to Quanzhen to learn martial arts. As an adult, Yang Guo (played by Huang Xiaoming) was bullied in Quanzhen Sect, but fortunately he was rescued by Xiaolongnu (played by Liu Yifei), the heir of the Tomb School. From then on, Yang Guo became Xiaolongnu's disciple and started a great love affair with her. At the same time, Guo Jing's two daughters Guo Fu (played by Chen Zihan) and Guo Xiang (played by Yang Mi) both fell in love with Yang Guo by mistake, but brought different fates to Yang Guo. At the same time, the Mongolian army was eyeing the Southern Song Dynasty. Facing national hatred, family feuds, and the love and hatred of his children, Yang Guo finally turned from a playboy into a great hero. After waiting for 16 years, he and Xiaolongnu finally got married.
