The problem was more complicated because Jin Yong and Roshi Hermit in Dragon Ball were fictional characters without real historical background and combat strength data. Therefore, it was impossible to determine whether they could defeat each other. But if we follow the plot of the novel and speculate that Master Roshi is a very powerful warrior in Dragon Ball, he has the power of a Super Saiyan and can transform into his strongest form. He also possessed powerful skills such as the Power of the Universe and the Unrestrained Mastery Skill, which could easily defeat many ordinary humans. In Jin Yong's novels, there were also many very powerful characters such as Huang Rong, Guo Jing, Ling Huchong, and so on. However, the combat power of these characters also depended on their cultivation and combat techniques, as well as the specific situation at that time. Therefore, he could not get a definite answer. If we only look at the plot of the novel, we can't be sure whether Jin Yong and Turtle Hermit can defeat each other because they are all fictional characters without real historical background and combat strength data.
