The palace of the general protecting the country was brutally framed and charged with treason. All loyal members of the family were killed. Only Major General Ling Canglan, who was pierced by thousands of arrows and thrown to the battlefield, managed to survive by virtue of his extraordinary will and body. She concealed her identity, transformed into a low-level policeman in Jingzhao Mansion, and returned to the imperial capital with overwhelming hatred. On the surface, she repeatedly solved strange cases, rose to prominence in Beijing, and approached the center of power step by step; secretly, she used all means to collect evidence, contact her father's old department, and establish her own intelligence network. In the process, she had numerous confrontations with Xiao Jue, the seventh prince who was responsible for supervising all officials and was ruthless. The two began to suspect each other and test each other, until they discovered a common enemy and were forced to join forces. Ling Canglan purged the court with thunderous means, killed his enemies with his own hands, vindicated his family, and his fame shocked the world. And when the final mastermind - the most unexpected person - emerges, a decisive battle that can overturn the entire dynasty begins. Ling Canglan and Xiao Jue fight side by side. In the baptism of blood and fire, they must not only uphold justice, but also clarify the deep love between the two that has long been out of control.
