Shen family's legitimate daughter Shen Jiahe suffered framing by her fiancé Gu Yunzhou, leading to her entire family being sentenced to execution. At death's door, she returned to the time when their marriage contract was about to be set. She decisively tore up the betrothal letter, returned the betrothal gifts, and demanded the return of one hundred thousand taels of silver borrowed by the Gu family. Relying on her exceptional business talent, Shen Jiahe withstood the Gu family's supply cutoffs and suppression, founded a commercial alliance, revitalized north-south supply sources, and step by step took charge of the Shen family's industries. Hand in hand with Lu Jingyuan, she investigated the old case of northern border military provisions, got entangled in the power game between the royal family and the prime minister, and uncovered Gu Yunzhou's background and the secret left by the late emperor. Facing frame-ups, mystery of background, and court struggles, Shen Jiahe did not rely on attaching herself to powerful nobles, but established the Empire's Commercial Office, broke the shackles of the times, and walked out her own path of rebirth.
