The modern cow horse travels back to Zhao Hu, a personal soldier under the account of the old prime minister during the time of Emperor Shenzong of the Song Dynasty thousands of years ago. When Yongle City was defeated, Zhao Hu rescued Qu Zhen, the deputy commander of the battle. From then on, he began to eliminate the traitors who betrayed the Song Dynasty and resisted the invasion of Xixia. After going through all kinds of things, he destroyed Xixia, Tubo, Daliao, and Jurchen, allowing the Song Dynasty to dominate the world, and let the Jingkang shame never happen again.
