Su Wanxing, the legitimate daughter of a wealthy Shanghai textile family, is reborn in 1975 at the critical moment when her stepmother, Zhou Meijuan, forces her to drink pesticide to protest an arranged marriage. In her previous life, Su Wanxing had refused the marriage to Lu Chenyuan, a military officer known as the Living King of Hell, in favor of a deceitful boyfriend. She was forcibly wed to Lu Chenyuan, neglected him, and went abroad, only to return after his death to discover his true nobility and that her parents were murdered by Zhou Meijuan. Killed while seeking revenge, Su Wanxing awakens in the past, resolved to change her fate and reclaim her family's stolen legacy.
Su Wanxing immediately agrees to marry Lu Chenyuan, shocking her stepmother and younger sister, Su Xueqing. Unbeknownst to Su Wanxing, Su Xueqing has also been reborn and seeks to steal Lu Chenyuan, whom she now recognizes as a powerful future commander. Su Xueqing attempts to sabotage the union by claiming Lu Chenyuan has agreed to marry her, but Lu Chenyuan publicly rejects her, declaring his intent to marry Su Wanxing. During a confrontation at a department store, Su Xueqing frames Su Wanxing for stealing a gold ring, but Su Wanxing exposes Su Xueqing's scandal with a local photographer, humiliating her in public.
Su Wanxing discovers she possesses a mystical space containing a spring of healing water and fertile land, activated by her mother's jade pendant. She uses this advantage to strengthen her body and prepare for life in the harsh northwest. She infiltrates the family textile factory, uncovering that Zhou Meijuan is having an affair with the accountant, Zhang Maocai, and they are embezzling family funds. Su Wanxing steals the incriminating ledger and the family's hidden treasures, including gold, antiques, and a will that disinherits her, before setting the house ablaze to destroy the evidence.
The Su family is left bankrupt and disgraced after Zhang Maocai and Zhou Meijuan are arrested for theft and adultery. Su Hongyi, Su Wanxing's father, attempts to rebuild his fortune by signing a lucrative contract with a mysterious businesswoman named Chen Wanyi, who resembles Su Wanxing. However, Chen Wanyi is an agent working for Su Wanxing. She deliberately provokes Su Xueqing into attacking her, then frames the sister for assault. Chen Wanyi uses this incident to void the contract and ruin the Su family's reputation in the textile industry, ensuring they cannot recover. With her enemies defeated and her assets secured in her space, Su Wanxing prepares to leave with Lu Chenyuan for the northwest, starting a new life with the man she now deeply loves and trusts.
