Her father and brother were bloody in the northern frontier, so she put on armor and went into battle, using her body as a woman to hold up the Shen family's army's undefeated flag. The world only knows that she is a peerless general who is undefeated in a hundred battles and the patron saint of the north, but they don't know how heavy the scars and loneliness are under that cold armor.
A carefully planned "fiasco" and a desperate "rout". When everyone thought she died on the battlefield and the empire's generals fell, she was like a frost blade hidden in the dark night, quietly cutting towards the carrion at the heart of the empire.
Conspiracy, betrayal, and a near-death sneak, she wants to tear apart the giant net covering the court and the border with her own hands, use the blood of the enemy to pay tribute to the loyal soul, and use her own hands to reshape the world. In this world, she wanted to get back everything she owed to the Shen family, one by one, with interest!
