After leaving the island, Ouyang Feng practises the "Nine Yin Manual" obsessively since he believes that the copy Guo Jing gave him is genuine. He kidnaps Huang Rong and tries to force her to interpret the verses for him, but she provides him with wrong information, without him knowing that he has been deceived. At the end of the novel, Ouyang Feng becomes insane due to practising the manual's skills wrongly, but his prowess in martial arts has also improved tremendously, and he defeats Guo Jing, Huang Yaoshi and Hong Qigong at Mount Hua.
