When it comes to adaptations of wuxia novels, TV and movie producers sometimes can't help going for the "Every Powerful Good Guy Gangs Up On The Super Powerful Bad Guy" ending. You know the drill: the bad guy has obtained some super martial art that makes him invincible. Even the most powerful good guys can't defeat him one-on-one, and even when ganging up on him, one or two of them must sacrifice their lives to secure the bad guy's defeat. Usually, the TV/movie producers need to radically rewrite the ending of a wuxia novel's story to make this work. Notable examples are TVB's DGSD '81 (where Siu Yeun San, Deun Yu, and Hui Juk had to team up to defeat a superpowered Mo Yung Bok, and Siu had to sacrifice his life) and LUK SIU FUNG III: THE BATTLE OF MO DONG (where Luk Siu Fung, Sai Mun Chui Sheut, Fa Mun Lau, See Hung Jak Sing, and Widow Fa had to gang up on the Jade Taoist/Old Sabre Tyrant, and See Hung and the widow sacrificed themselves). Leung Yu Sang's DRAGON INN ended this way (although I think that was true to the novel and not an innovation of the movie), but how many wuxia novels actually ended this way?
