In Kunlun Mountain among the Shu Mountains, the head of the sect, Master Gu Yue (Cecilia Cheung), fell in love with his apprentice Xuan Tian Zong (Ekin Cheng). She had a premonition that the evil Youquan Blood Demon would attack Kunlun. Knowing that she was powerless to resist, she used an excuse to drive him down the mountain to save Tian Zong's life, and handed over Kunlun's secret weapon "Sun and Moon Golden Wheel" to Tian Zong, while she was killed by the Blood Demon, and all the spiritual energy of Kunlun Mountain was sucked away. Two hundred years later, the evil forces invaded the righteous again. The founder of Emei, Emei Zhenren (Sammo Hung), feared that this battle would hurt the mortal world, so he sent his eldest disciple Dan Chenzi (Louis Koo) to the foot of the mountain to alienate the warring armies in the mortal world. On the way, he met Cheng Letian (Zhang Ziyi) and Xuan Tian Zong, but accidentally discovered the secret of the Blood Demon and fell into a trap. At the moment of life and death, Emei Zhenren led his disciples to rescue, and Xuan Tian Zong suddenly discovered that one of the female disciples, Li Yingqi (Cecilia Cheung), looked exactly like his master, Master Gu Yue. At the same time, Master Emei discovered that he had fallen into the trap of the Blood Demon, and a more dangerous battle between good and evil was about to begin...
