Zhao Yun
Zhao Yun, also known as Zhao Zilong, fought together with Liu Bei as an ally during Liu Bei's early career, leaving a very close relationship with each other in the novel. Finally when Zhao Yun and Liu Bei met in Ye, Zhao Yun decided that he would follow Liu Bei's leadership for the rest of his life. During his career with Liu Bei's force, Zhao Yun protected Liu Bei's family, and saved Shu Han's crown prince Liu Shan from numerous battles. Zhao Yun's most legendary battle was to save Liu Shan, who was an infant at the time, from Cao Cao's encirclement. During the Battle of Changban, isolated by Cao Cao's army, Zhao Yun held Liu Shan in his armor, slew more than 70 enemy warriors alone, and escaped the scene without disturbing the infant's sleep. In Shu Han, Zhao Yun led Liu Bei's royal guards, ensured the safety of the royal family, and kept the capital city in peace.
