Three years after his body was covered in snow at the border, Shen Zhao was sent to guard the border in a desperate situation as a death row prisoner, but deep in the ice field, he awakened the memory of being a famous general of Dayin in his previous life. He used his flesh and blood to recast the soul of his army, secretly integrated the remaining soldiers, tamed the barbarian war horses, and deployed behind enemy lines. Three years later, he returned to Beijing with the head of the enemy commander, only to find that the court had been infiltrated by powerful ministers and foreign emissaries. His former mentor turned out to be the mastermind of treason, and the bones covered by the snow turned out to be his wife and children who he had not saved in his previous life. He must reshape a military and political system that does not belong to this era amid imperial power strife and national hatred. His opponent is not only foreign enemies, but also the decadent dynasty itself.
