In the middle of winter in Beijing, the iron gate of the prison creaked open, and Xiao Ce walked out of the darkness dragging the scars left by eight years in prison. Eight years ago, he was the youngest general in the Nanxuan Kingdom, and his silver armor was stained with blood to protect his family and country; eight years later, he was a criminal accused of "collaborating with the enemy and treason". The pain of the tragic death of his relatives and the betrayal of his best friends has long been engraved in his bones.
Emperor Xiao Yu suddenly released him from prison. Was it mercy or a trap? Beidi on the border is watching with eager eyes, and the undercurrent in the court is turbulent. The black hands who framed him back then are still in high positions. When he meets young Su He by chance, his pure goodwill becomes the only warm light on his way to revenge, but it also puts him in a dilemma between "protecting people" and "revenge".
Is the old department still there? How to redress an injustice? When Xiao Ce picks up the rusty sword, the wind and snow in Nanxuan Kingdom will eventually be ignited by the return of the God of War.
