In Jin Yong's martial arts novels, the Nine Yang Scripture and the Nine Yin Scripture were both created by Patriarch Bodhidharma, but Jin Yong did not clearly state who the real master of these two scriptures was. However, we can infer some clues from some of the plots and characters in the novel. The Nine Yang Scripture and the Nine Yin Scripture were both martial arts secret manuals, and their names also indicated their uniqueness. The Nine Yang Scripture focused on masculine qi and emphasized strength, while the Nine Yin Scripture focused on feminine beauty and emphasized intelligence. These two sutras were very important in the novel and it was said that they were created by different masters and might involve different martial arts sects or martial arts figures. In the novel, there were some characters like Duan Yu, Xu Zhu, Huang Yaoshi, etc. Although they didn't cultivate the Nine Yang Scripture or Nine Yin Scripture, they were all influenced or learned from them. Therefore, we can infer that although the Nine Yang Scripture and the Nine Yin Scripture were both created by Patriarch Bodhidharma, they may not be completely independent existences. Instead, they may have been influenced or borrowed by other martial arts masters.
