杨康
When Yang Kang finally meets his sworn brother, Guo Jing, the latter attempts to persuade him to take the Song Empire's side. Although Yang Kang initially agreed to join the Song Empire, he changes his mind later after witnessing how the Han Chinese society of the Song Empire is plagued by problems such as political corruption, internal conflict, and cowardice in the face of Jurchen aggression. Disgusted, Yang Kang succumbs to the temptation of being a Jurchen noble and denounces his ethnicity again. He collaborates with the Jurchens to exploit his own race (the Han Chinese) and pretends to have acknowledged his ethnicity. At one point, he attempts to kill Guo Jing by stabbing him with a dagger when Guo tries to persuade him to revert again. He murders Ouyang Ke so that he can take the latter's place as Ouyang Feng's apprentice. Yang Kang is also responsible for the deaths of five of the "Seven Freaks of Jiangnan", and for framing Guo Jing for the murder of Ouyang Ke.
