Susu is pregnant. A few months later, Xie Xun went berserk and wanted to kill the two. At this time, the cry of the baby (Zhang Wuji) woke Xie Xun up. Xie Xun used the Dragon Slaying Sword to carve a wooden model of the Dragon Slaying Sword as a full-month gift for Wuji. Susu suggested that Wuji recognize Xie Xun as his adoptive father. Xie Xun recounted the past of his master Cheng Kun (Yuan Zhen) forcing his wife to rape and kill his parents, wife and children (when the six major sects besieged Guangmingding, they learned that Cheng Kun's junior sister was taken away by Yang Dingtian, which was the fundamental reason why Cheng Kun destroyed the Mingjiao). Xun killed people everywhere to force Kun to show up, and wrote "Cheng Kun, the Hunyuan Thunderbolt Hand" on his name after killing them. But after killing many people, he did not see his master, and wanted to kill Yuanqiao to shock the martial arts world. Shaolin Kongjian stepped forward to stop him. Xun was undefeated by Kongjian, and in order to see Cheng Kun, he pretended to be injured and attacked Kongjian, almost killing him. Cheng Kun has not appeared yet, and Yin Zhang and Xie have become sworn brothers.
