襄陽・樊城の戦い
Almost all of the characters in the series are fictional except Huang Daopo, Emperor Duzong, Mongol general Bayan, and Yelü Chucai. Most of the plot does not match actual historic accounts. There are references to the death of Emperor Duzong, the succession and abdication of Emperor Gongzong, Battle of Xiangyang, Battle of Yamen and the deaths of the Song's last two emperors; Emperor Duanzong and Emperor Huaizong.
