The series is set in 17th-century China during the
Ming dynasty. The corrupt eunuch
Wei Zhongxian holds sway over the Ming government and plots to usurp the throne with the aid of his supporters in the
wulin. He instigates Meng Shentong to kidnap Li Shengnan and force her to hand over a highly coveted martial arts manual. The great hero Jin Shiyi rescues Li Shengnan and combines forces with her to defeat Meng Shentong. When Li Shengnan dies of her injuries, Jin Shiyi feels so deeply saddened that he leaves the
wulin to lead a reclusive life on a remote island. Years later, Jiang Haitian, Jin Shiyi's apprentice, has become a leading figure in the
wulin and started a rebellion against the corrupt Ming government. Shi Baidu, the chief of the Six Harmonies Clan, secretly pledges allegiance to Wei Zhongxian and promises to deal with the rebels. When Jiang Haitian invites guests from throughout the
wulin to attend his daughter's wedding, Shi Baidu seizes the opportunity to make an attempt on Jiang Haitian's life. Shi Hongying, Shi Baidu's sister, tries to dissuade her brother from helping Wei Zhongxian, but he ignores her so she sneaks out to warn Jiang Haitian. Around this time, Jin Zhuliu, Jin Shiyi's son, sets foot on the mainland in search of adventure. By chance, he meets Shi Hongying and falls in love with her. He also encounters Li Shengnan's nephew, Li Shengnan, and becomes
sworn brothers with him. They work together with their
wulin allies to resist Wei Zhongxian. == Cast ==
