Gu Wan, a veteran of a thousand quick-transmigration missions, expected to be reborn as a wealthy heiress after completing her contract with System 3888. Instead, the system abruptly transported her into the body of a cannon fodder female supporting character in a 1983 period novel. In this new reality, she inhabits the body of Gu Wan, a girl who was switched at birth with a fake daughter and raised as a slave by the abusive Gu family in Zhaojia Village. The original owner was drugged by her adoptive parents, Gu Jianshe and He Cuifen, and her sister Gu Xiuhua, who conspired to ruin her reputation by leaving her with a village bachelor in a thatched hut. Their plan was to expose her in front of villagers, forcing her out of the family so the fake daughter could remain in Shenzhen as a wealthy heiress.
However, the real Gu Wan, now in control, turned the tables. She knocked out her abusers, administered potent drugs to them, and staged a scene where the villagers discovered the mother and daughter in compromising positions with the bachelor. While the Gu family faced public humiliation and social ruin, Gu Wan escaped into the mountains to cool the drug's effects. There, she encountered Mo Beishen, a powerful special forces commander who had also been reborn from the future to 1983. Mo Beishen, who suffered from a severe allergy to women in his previous life, found that Gu Wan was the only person he could touch without reaction. Their encounter, sparked by her drunken advances, led to a passionate night together.
The next morning, Gu Wan revealed her true identity and the truth about the child-switching scandal. She explained that she was not the biological daughter of the Gu family and that her presence threatened the fake daughter's status. Mo Beishen, intrigued and protective, agreed to help her. They decided to marry quickly, with Mo Beishen utilizing his military connections to expedite the paperwork. Together, they returned to Zhaojia Village in a military jeep, shocking the villagers and the Gu family.
Upon arriving, Gu Wan confronted her adoptive family. She physically overpowered Gu Xiuhua and Gu Tianbao, who attacked her, and publicly exposed their crime of stealing her identity and attempting to murder her. She demanded 20,000 yuan in compensation for nineteen years of mistreatment and the severance of all familial ties. The villagers, siding with Gu Wan after hearing the truth, pressured the Gu family into compliance. Gu Wan, accompanied by Mo Beishen, stood firm, declaring her independence and setting the stage for her new life as the wife of a powerful military commander, leaving the Gu family to face the consequences of their greed.
