Plot
The film is a spin-off of the original story of The Heaven Sword and Dragon Saber. Zhang Wuji retrieves the Heaven-reliant Sword and the Dragon-slaying Saber and places them in the Ming Cult's headquarters. He carves the inscriptions from the Nine Yang Manual on the walls of a secret chamber and asks his godfather Xie Xun, who has become a monk, to help him guard the chamber. Zhang returns the original copy of the manual to the Shaolin School.

Song Qingshu, a defeated villain from the original story, returns and starts a reign of terror. He traps a beautiful Mongol princess and masters a new Yin and Yang-combined martial arts technique, becoming almost invincible. Zhang Wuji has to put an end to Song Qingshu's rampage.
