馬忠
Fu Shiren and Mi Fang appear in the novel again before the Battle of Yiling. They overhear a plot to kill them, so they assassinate Ma Zhong (馬忠), who captured Guan Yu in an ambush, and bring his head along when attempting to return to Liu Bei's side. However, Liu Bei refuses to accept them and orders Guan Xing (Guan Yu's son) to execute them for betraying his father.
