Lü Bu is outraged and goes to Wang Yun's house to vent his frustration. Wang Yun then uses the opportunity to instigate Lü Bu to join the plot to kill Dong Zhuo. Lü Bu kills Dong Zhuo when the latter shows up at a ceremony for Emperor Xian to abdicate the throne to him; the ceremony is actually a trap set by Wang Yun and Lü Bu. After Dong Zhuo's death, his former followers, led by Li Jue and Guo Si, attack Chang'an to avenge their lord. Lü Bu is defeated in battle and forced to flee.
