In the sequel, Ouyang Feng accepts Yang Guo as his godson and teaches him the Toad Skill. He becomes insane eventually as a consequence, but his prowess in martial arts also increases tremendously in an unorthodox manner. He attempts to seize the Nine Yin Manual, a book detailing powerful martial arts and inner energy techniques, but is tricked into practising skills based on a corrupted version of the manual. In the first novel, he is depicted as a ruthless villain who resorts to all sorts of unscrupulous means to achieve his goal of becoming the most powerful martial artist in the jianghu.
Ouyang Feng is best known for his signature martial arts technique, the Toad Skill, and his expertise in toxicology. He is the 'Western Venom' of the Five Greats of the wulin (martial artists' community) during the Song dynasty, alongside Wang Chongyang, Hong Qigong, Huang Yaoshi and Duan Zhixing.
Ouyang Feng is a fictional character in the wuxia novel The Legend of the Condor Heroes and its sequel, The Return of the Condor Heroes, by Jin Yong. In this Chinese name, the family name is Ouyang.
