Wubang, hailed as the greatest fist fighter under heaven, kills people everywhere in his quest to claim the title of the world's best. When Daoist Master Qingmu, who lives in seclusion at a temple, hears about this, he finds Wubang and tells him he has been used. If he doesn't change his ways, a young man carrying a Qingmu Sword will one day kill him. But Wubang refuses to change. In an attempt to find the young man, he massacres Du Feixiong's village, wiping out the entire Du family. Amid the chaos, Du Feixiong's second son's wife escapes with her son, Du Peng. Du Feixiong's two sons were away from home and survive the massacre. When Wubang learns that they have returned, he pursues them to the Western Regions. Someone really has been using Wubang, turning him into a devil. In the Western Regions, the devil Wubang unexpectedly discovers who has been manipulating him. She has established an assassin organization and is recruiting assassins throughout the Western Regions. Realizing that Wubang is beyond her control, she can only kill him. Wubang returns to Wulong Town, where Du Feixiong's second grandson, Du Peng, comes to seek revenge, wielding a green wooden sword.
