Shen Zhao, the former Dayin female commander-in-chief, who was framed and lost his command, captured and humiliated, used his mutilated body to seize the enemy's commander-in-chief seal with his own body, and bloodbathed the three armies. Yan Wuji, a young marshal from the enemy country, secretly protected her, but he didn't know that she was the enemy of the family. Liu Yanrou, a medical officer, worked undercover for five years, struggling for his daughter's loyalty. Scout Bai Ling stole pictures and sent messages, triggering an undercurrent in the army. When the secret box of the blood edict was opened, the old stigma actually led to the shocking conspiracy of the imperial family - what she took was not the handsome seal, but the corpse of the entire dynasty.
