In the previous life, Su Jinye, the legitimate daughter of the Shangshu Mansion, was gentle and virtuous, but she was framed by her cousin and her fiancé. Her family was destroyed, her relatives died tragically, and her own life was ended in the cold palace by Sanchi Bai Ling. When she opened her eyes again, she was back to the age of sixteen, the night before her fate changed.
In this life, she lost her innocence and hid her sharp claws. In order to turn things around, she turned her attention to the powerful King of Zhenbei, Xie Xuan - the cold-faced God of War who she had avoided in her previous life, but who ended up collecting his body for her. She carefully weaves a web of love, approaches step by step, and turns him into the sharpest sword in her hand.
At first, Xie Xuan only felt that the little girl's eyes were complicated, and her calculations were written on her face, but she still pretended to be harmless. He watched her acting with cold eyes, but he fell into the drama unknowingly. When she finally achieved her goal and wanted to pull away, he grabbed her wrist and said in a low voice: "You want to run away after using her? Nothing in this world is that cheap."
From testing each other to joining hands, from being hypocritical to trusting each other in life and death. When the conspiracy reappears and the enemy is in front of them, they are each other's armor and weakness. In the whirlpool of intrigue and true love, they fight their way out and find each other's light.
