Humiliated, Jiang Zhong collaborates with Instructor Zhang and garrison inspector Zhang Mengfang () to get back at Wu Song. Inspector Zhang pretends to admire Wu Song for his mighty strength and invites him to stay at his manor. Wu is caught in an ambush and sent to prison on the false charge of theft. After being jailed for six months, during which Shi En thwarts a plot to murder him in prison, Wu is exiled to another place. Shi En warns him of danger when sending him off. Indeed Jiang Zhong has bribed Wu‘s escorts to murder him on the way with the help of two of his students. When the group come to Flying Cloud Pool (), Wu breaks up his cangue and kills all the four men. He returns to Inspector Zhang's manor and finds his way to the Mandarin Ducks Tower (), where the trio — Jiang and the two Zhangs — are drinking in celebration of his certain death. He kills all three and practically the whole family of Inspector Zhang. Overall 15 are killed in Zhang's house. He then writes the characters "The killer is Wu Song the tiger-slayer" with blood on a wall before leaving.
