“What you cannot obtain on the battlefield, do not expect to get at the negotiating table.” The Fuping Battle of the fourth year of the Jianyan era was the decisive battle for the Song and Jin Dynasties' struggle over Shaanxi and the northwest. The Song army suffered a crushing defeat, and the strategic focus of the Song Dynasty shifted to defending Sichuan.

When a soul from the future awakens during the Fuping Battle, everything changes.
