An imperial edict slandering the enemy and treason plunged the Shen family into the abyss. His father and brother died unjustly in prison, and his female family members were exiled thousands of miles away. Their former glory fell overnight.

Shen Zhiyi raised his eyes, with a sharp light in his eyes that he had never seen before: "Your Highness, what I want is more than just clearing away the reputation.
