In the fourteenth year of Zhenguan, Goguryeo fell, the foundations of the great clans east of the passes were shattered, and grain transport connected court and country.
Li Chengqian, once troubled by the struggle over succession, has recovered from his leg injury and now sits securely in the Eastern Palace. Tibet threatens Hexi from beyond the borders, Xueyantuo occupies the grasslands, and his brothers scheme in secret. The undercurrents have never subsided.
When a Tibetan envoy presents an arrogant letter at the Taiji Palace to pressure the court, he tears it up in front of everyone and sounds the call to secure the northern frontier.
Gao Yuan, battered by wounds and illness, traverses thousands of miles of grassland, risking life and limb to unite the tribes. Li Chengqian directs the campaign from behind the scenes, inspecting the troops through wind and snow and laying plans for the decisive battle at Yudu Junshan. Bloodshed on the battlefield intertwines with court intrigue, while broken pieces of a long-buried secret from the Eastern Palace lead to a vast game of strategy spanning the Central Plains and the grasslands.
