Dugu Qiubai is a fictional character who is mentioned by name in three wuxia novels by Jin Yong (Louis Cha). He does not appear in any of the novels because he lived in an era long before the events of the novels took place. Nicknamed "Sword Devil" (劍魔; jiàn mó) to reflect his prowess in and devotion to the practice of swordplay, he attains the philosophical level of "swordsmanship without a sword", which means that he uses swordplay techniques in combat without the physical existence of a sword.
