The imperial court orders Qingfeng Sect to help wipe out the Ming Cult, shattering the peace of the martial world. To avert the crisis, Qingfeng Sect disciple Chu Yichen heads for the Ming Cult's headquarters. Along the way, he meets the quirky Su Yao, who guides him there. The two successfully meet Ming Cult leader Murong Yan. The three plan to work together to expose the court's conspiracy, but their plan fails when Zhao Lingfeng, Qingfeng Sect's second disciple, betrays them for personal gain. The imperial army surrounds the Ming Cult, and war erupts across the martial world. With support from the Beggars' Guild, the Emei Sect, and other factions, the martial world eventually drives back the imperial forces. As Chu Yichen and Murong Yan fight side by side, feelings begin to blossom between them.
However, the court then backs the Shadow Hall to stir up conflict between the Beggars' Guild and the Shaolin Sect. Chu Yichen and Murong Yan do everything they can to mediate. Chu Yichen risks his life to gather evidence and expose the conspiracy, then faces Ye Wuhen in a duel. Murong Yan is gravely wounded while saving him. Later, Zhao Lingfeng is hunted by the court and returns to Qingfeng Sect to beg forgiveness. Chu Yichen calls on the various factions to form a martial alliance and fight their common enemy. Despite many setbacks, they succeed. When the court launches another campaign against them, the martial alliance lays an ambush and wins a decisive victory. Chu Yichen and Murong Yan resolve to uphold chivalry and protect the martial world, which finally enters a period of relative peace.
