Fifteen years ago, hundreds of masters from the good and evil factions joined forces to defeat the demon sect, but they died together with the new demon on Guiwei Island. There are only two survivors - the righteous swordsman Zhao Yunhe and the devil's heroine Shen Qingbi. Trapped on an isolated island, they fell in love from hostility and gave birth to their son Jiang Tian.
Fifteen years later, in order to let his son see the real world, a family of three took a boat trip to the sea. Both parents disappeared in the huge waves. Jiang Tian drifted alone and was rescued by pirates. He defeated the pirates and rescued the young Tianjiu. He took the 108 magic weapons and martial arts treasures left by his parents to Wudang Mountain for help, but was turned away because of his mother's identity as a "witch".
