The Great Chu Empire's borders are in grave danger. Xiao Ce, the Marquis Who Guards the North, is reborn in the imperial court during peace negotiations. Having learned from his previous life, in which his foolish loyalty led to a tragic death, he surrenders his military commander's tiger tally and withdraws from public life, then joins Shen Jinghong, a surviving descendant of the previous dynasty. After the Northern Barbarians breach the capital, Xiao Ce takes advantage of their complacency and launches a nighttime raid to retake the city, drive out the invaders, and restore the Chinese realm! The two then reorganize their armies and launch a northern campaign. At Eaglefall Valley, Xiao Ce annihilates the Northern Barbarian forces and kills their Khan. Shen Jinghong ascends the throne and establishes the Great Jing Dynasty, appointing Xiao Ce as regent. Together, they share imperial power and usher in an era of peace and prosperity.
