Song Yuanzhi, the legitimate daughter of the general, was reborn at the moment of death when her brother-in-law Xie Xiao fell into the ice lake. In her previous life, she rushed to rescue her, but in exchange she was imprisoned by Xie Xiao and her concubine Song Xuening to have her blood drawn and tortured to death. In this life, she watched with cold eyes, backhandedly passing the responsibility of rescuing to the concubine who had a clear vision above all else, and let her suffer the consequences. Faced with Xie Xiao's groundless accusations, Su Hechen, the new top scholar in the science, stepped forward to protect her and officially announced their engagement, breaking the tragic fate of her previous life. From then on, Song Yuanzhi worked step by step, tearing apart the hypocritical concubine and the cold brother-in-law, shattering their plots time and time again, making them pay a heavy price for their evil deeds in their previous lives.
