The Five Tiger Generals, Cao Cao, Xiao Qiao, Diao Chan and Xiu/Liu Bei are celebrating in a restaurant when Guan Yu's arm suddenly petrifies after it got shot by a poisonous arrow during the Eight Doors Golden Lock Formation's final trial. They drag him to see miscellaneous doctors, including witch doctors, all end up saying that his arm is incurable. Though Famous Doctor and Ma Chao solve their issue, she still refuses to heal Guan Yu and the responsibility is passed on to her apprentice, Hua Tuo. Hua Xiong successfully heals Guan Yu's arm within 10 days.
