典韋
After Dong Zhuo's defeat, Cao Cao focuses on uniting the land. He is surrounded by enemies: Dong Zhuo's general Lu Bu has taken over all of Dong Zhuo's troops and taken Xiapi Castle; Zhang Xiu has rebelled in Wan Castle; to the north, Yuan Shao threatened to swallow the north whole. Cao Cao defeated Zhang Xiu at Wan Castle, with his guard Dian Wei holding foes back in the burning castle. Cao Cao, having escaped, defeats Lu Bu in alliance with Liu Bei at Xiapi in 198 AD, exterminating his army and gaining several officers. Cao Cao's final victory is at the Battle of Guandu in 200 AD, where he destroys Yuan Shao's army before he even arrives.
