A hundred years ago, immortals and demons fought against each other and thousands of beasts slaughtered the city. The founder of Xianjian Sect fought with the leader of the demon clan, Youhuang, for seven days and seven nights, and finally Youhuang was defeated and fled. A hundred years later, Zhang Zhilin became the new leader of Xianjian Sect. He used the purple and green swords that could kill the demon king as bait to lure Youhuang out, but found that the town was full of evil corpses and all the women were missing. Xianjian Sect flew down the mountain to rescue the people, but accidentally discovered the conspiracy of the demon clan to harm people with poison and Youhuang to absorb the essence of women to practice magic. In order to kill all the evil demons and save the people, Xianjian Sect set up the Tiangang Beidou formation to fight against the invasion of the demon clan. Zhang Zhilin and his wife launched a final counterattack against the revengeful Youhuang!
