Impressed by the hearsay that "The martial worlds gem Dragon Sabre commands the world and none dares to disobey", the three "Animals" of Chang Pai braved everything to steal it from the Hai She clan.

Playing around in the Temple, Kuo Shang struck an acquaintance with San Feng, and the two became good friends. Subsequently, Priest Wu Shih recognized Kuo Shang to be the daughter of Kuo Tsing, and extended warm hospitality to her. The Saint of Kun Lun deliberately makes trouble in the Temple on the pretext of searching for the lost classic.

Wu-chi loves Chiu-chen but he is always made a scene on by her and Wei Hi, her cousin. Wu-chi knows from Chiu-chen that Tsui-shan has saved the Tzu family. To prevent misunderstandings, Wu-chi does not tell them his true identity.
