Dong Zhuo, confident in his success, was slain by his follower Lü Bu, who plotted with minister Wang Yun. Lü Bu, in turn, was attacked by Dong Zhuo's former officers: Li Jue, Guo Si, Zhang Ji and Fan Chou. Wang Yun and his whole family were executed. Lü Bu fled to Zhang Yang, a northern warlord, and remained with him for a time before briefly joining Yuan Shao, but it was clear that Lü Bu was far too independent to serve another.
