李愬
In 192, Li Su joined Lü Bu and Wang Yun in a plot to assassinate Dong Zhuo in Chang'an. He led about a dozen soldiers and pretended to stand guard near the entrance. When Dong Zhuo arrived, Li Su tried to stab him with a "ji", but Dong Zhuo's body armour saved him. Lü Bu then came up close and killed Dong Zhuo.
