When Emperor Zhao Heng of the Song Dynasty succeeded to the throne, there were Khitan cavalry in the north looking at him, party heroes in the west establishing their own rule, and the barbarians in southern Xinjiang were in constant turmoil. Lin Xiao, a border soldier with a humble background, rescues the royal emissary by chance, and is forced to get involved in the turbulent court battles and war-torn battlefields.

In this turbulent era, he opened a completely different path to a powerful country for the weak Song Dynasty.
