In her previous life, Shen Qingluan (the heroine), the legitimate daughter of the prime minister, was madly in love with the prince Murong Jue, but was tricked by her concubine Shen Yurou and the prince. She was ruined and died tragically in the cold palace. After being reborn, she vowed to pay with blood. In order to take advantage of the opportunity for revenge, she took the wrong approach and took the initiative to marry the powerful and ruthless regent Murong Che (the male protagonist), who was on the same level as the prince. They thought it was a contractual marriage for mutual use, but in fighting side by side and sharing life and death again and again, they uncovered the mystery of the past life and discovered each other's hidden sincerity and shocking identity. The two work together to stir up the chaos in the court, smash the conspiracy, and finally reach the top, taking control of the mountains and rivers together.
