The eunuch Wei Zhongxian dominates the political scene and plans to bring the wulin (martial artists' community) under his control and usurp the throne.

He instigates Meng Shentong to kidnap Li Shengnan, the leader of the Heavenly Demonic Cult, and force her to hand over a highly coveted martial arts manual, the Baidu Zhenjing.

The great hero Jin Shiyi interferes, rescues Li Shengnan, and combines forces with her to defeat Meng Shentong.

20 years later, Wei Zhongxian feels threatened by Jiang Haitian, Jin Shiyi's apprentice, who has garnered much support from the wulin and started a rebel movement against the Ming government.

She tries to advise her brother against helping Wei Zhongxian but he ignores her, so she sneaks out of the house and travels to Jiang Haitian's residence to warn him about the impending danger.
