Su Jinning, the eldest daughter of the Duke of Zhenguo, mistakenly believed in the scumbag scout Gu Yanzhou and the scheming concubine Su Yuwei in her previous life. The two teamed up to rob the family property, murder her parents, and eventually died tragically in the cold palace. Returning from the dead with overwhelming hatred, she tore her concubine's concubine to pieces on the spot and broke off her previous engagement in public, shocking everyone.
From then on, Su Jinning took the memory of her past life and worked step by step with all kinds of clever plans: taking back the power of the Su family, tearing apart her mother and concubine, and driving them out of the house; she planned to end the official career of the scumbag Gu Yanzhou, and even calmly proposed a divorce at the time when he was most proud of his marriage, so that he could leave the house and lose his reputation.
In a desperate situation, she encounters Xie Heng, the powerful King of Dingbei - this cold-faced prince who secretly helped her in his previous life but failed to save her. This time he recognizes her tenacity and intelligence at a glance and becomes her strongest support on the road to revenge.
The female protagonist builds a business empire and accumulates power with her business talents; the male protagonist is cold on the outside and warm on the inside, and is affectionate and protective. The two work together in court intrigues to liquidate the remaining power of the Gu family and expose Gu Yanzhou's heinous crime of colluding with foreign enemies.
The bloody feud was avenged, and the family's injustice was revealed. Su Jinning put aside her obsession, accepted Xie Heng's love, and married King Dingbei. From then on, the couple stood side by side, sharing power, and continued to write a stable and complete life in the brocade tent.
