In her previous life, Xin Xue cleared away all obstacles for her sweetheart Yan Xuechi, and even had her hands stained with blood. However, she ended up dead with random arrows piercing her body and gouging out her heart. Only on her deathbed did she realize that she was just a pawn paving the way for Princess Bai Yueguang. When she breathed her last with regret, broken snow mixed with blood foam was choked into her throat: "Snow must be dirty after all, people... Are born to be broken."
When she opened her eyes again, she turned into a ball of chaotic fetal breath, curled up in a strange belly. This dynasty emperor named Gao Xinling, in the name of "the princess descended from heaven", borrowed the ancient artifact "Huayingzhuanpo tripod" to transfer her from the mortal body, and earned her the golden position of the first crown princess in the Huangji Celestial Dynasty where women are the most important.
In ten years, Xin Xue grew from an ignorant baby to an iron-blooded prince. Under the gentle protection of her adoptive father Gao Xinling, she dealt with the ambitious female prime minister Ji Yu while hiding her past life memories and observing the situation coldly. She thought this was a one-sided redemption, but she didn't know that Gao Xinling had used blood as a chess piece as early as ten years ago - in order to avenge the emperor's sister and stabilize the precarious royal power, he personally shaped her into a dynasty sword.
