Zhang Cuishan (Francis Ng) and his wife and son Zhang Wuji (Jet Li) set out from the isolated island to celebrate his master's 100th birthday. On the way, they were ambushed and Zhang Wuji was hit by the Ice Palm. In Wudang Mountain, Zhang Cuishan and his wife were forced to death by the major sects. Zhang Wuji could no longer practice martial arts and could only survive by relying on the daily infusion of true energy from Zhang Sanfeng. Zhang Sanfeng's actions aroused the jealousy of Song Qingshu (Zou Zhaolong), who joined forces with the female disciple Zhou Zhiruo (Gigi Lai) of Emei to deal with Zhang Wuji. The Saint of the Ming Cult, Xiao Zhao (Yau Shu-ching), changed Zhang Wuji's fate. He first met a master on the cliff to cure the ice poison in his body, learned 90% of the "Nine Yang Magic Skill", and practiced the "Heaven and Earth Great Shifting Heart Method" in the forbidden area of the Ming Cult. When he learned that the Mongolian Princess Zhao Min (Zhang Min) designed to make the six major sects of the Jianghu besiege Guangmingding to annihilate the Ming Cult, Zhang Wuji decided to go through fire and water to save the Ming Cult.
