Yun Zhan, an abandoned disciple of the Xingxiu sect, has a bloody feud and is hunted by the entire Western Region martial arts. In a desperate situation, he meets Li Suyi, a talented girl from the south of the Yangtze River who traveled west alone to find her missing father, and Xuan Nan, a Shaolin disciple who was ordered to go west to meet the Buddha's bones.
