In the martial arts world of Jin Yong, there was only one person who could challenge Shaolin Temple and defeat the sweeping monk with his true strength, and that was Duan Yu. Duan Yu was the third son of the Emperor of Dali, Duan Zhengchun. He was proficient in the Duan family's martial arts, including the "Six Meridians Divine Sword". In the novel, Duan Yu had a duel with the sweeping monk in Shaolin Temple and finally defeated the sweeping monk with his own strength and wisdom. In the battle, Duan Yu used the "Six Pulses Divine Sword" of the Duan family of Dali to attack the sweeping monk. At the same time, he used his own intelligence to avoid the sweeping monk's attacks. Finally, he took advantage of the sweeping monk's carelessness and defeated the sweeping monk with a delicate "Northern Dark Divine Skill". Therefore, Duan Yu's strength and ability could not be ignored in Jin Yong's martial arts world. He was able to challenge the Shaolin Temple alone and his true strength could defeat the sweeping monk. He was a respectable character in the novel.
