The most powerful martial arts in Jin Yong's novels were not the Nine Yang Sutra because the evaluation and ranking of martial arts in different novels might be different, and the characteristics and usage of martial arts in different novels might also be different. In " Eight Demigods ", the sweeping monk was considered one of the most powerful martial arts. He could resolve the troubles in people's hearts through mysterious methods and achieve the sublimation of the state of mind. Although the Nine Yang Scripture was a very famous martial arts secret manual, not everyone could master and use the contents. Dugu Qiubai's martial arts were considered to be the highest in the " Smiling Proud Pugilistic World ". He could reach the peak of martial arts through the method of winning without any moves and his swordsmanship had reached the extreme. However, in this book, the Nine Yang Scripture was not Dugu Qiubai's main weapon. Therefore, the most powerful martial arts in Jin Yong's novels might be different according to the plot and character setting of the novel. It needed to be evaluated according to different novels.
