The Whole Family Travels Through Time to the Era — Fortune Baby Holds a Hundred-Billion Medical Space

Dr. Su Wanwan, a brilliant researcher from the modern era, dies from overwork and transmigrates into the body of a seven-year-old girl with the same name in 1970s rural China. The original owner was an outcast in Qingshui Village, suffering from a disfiguring skin disease and bullied by her cruel grandmother, Old Madam Su, and her uncle’s family. Upon waking in a dilapidated mud house, Su Wanwan discovers she has brought her fully equipped medical research laboratory with her. This portable space contains advanced pharmaceuticals, nutritional supplements, and medical equipment that function as a cheat in this resource-scarce era. After using a nutritional solution to recover her strength and cold medicine to cure her ailments, she realizes she can treat her own skin condition and improve her living standards without anyone knowing her secret.

The core conflict centers on the Su family’s exploitation of Su Wanwan and her mother, Ye Xiu’e. Ye Xiu’e is a respected barefoot doctor who sends her entire monthly subsidy to the family, yet she and her daughter are forced to live in a crumbling hut while the rest of the family enjoys a new brick house built with Su Wanwan’s late father’s compensation money. Old Madam Su and her son, Su Wangcai, view the mother and daughter as burdens and have subjected the child to years of physical abuse and neglect. The situation escalates when Su Cuifen, the cousin, and her brothers torment Su Wanwan, leading to the original owner’s death by fright. Now, with Su Wanwan’s changed personality, the family’s schemes begin to unravel. When Ye Xiu’e returns home to find bruises on her daughter, she confronts the family with a cleaver, exposing their greed and cruelty in front of the villagers.

Key turning points include Su Wanwan’s retaliation against her bullies and her mother’s growing defiance. When Su Cuifen and her brothers attempt to scare Su Wanwan with a snake, she turns the tables, causing Su Cuifen to accidentally scald herself with hot water. Su Wanwan manipulates the situation to protect herself, leading her mother to believe the children were the aggressors. Simultaneously, Ye Xiu’e discovers that her two hundred yuan share was used by Su Wangcai to buy a bicycle. She demands its return, but the money is gone. The family then attempts to force Ye Xiu’e into a marriage with a known abuser, Zhu Fenqiang, hoping to get rid of her so Xu Shi, the aunt, can take over the barefoot doctor position. Su Wanwan helps her mother sabotage the matchmaking attempt by faking a severe illness, causing the prospective in-laws to flee in terror.

As the story progresses, Su Wanwan solidifies her bond with her mother, who begins to plan for independence. Ye Xiu’e decides to separate from the Su family and reclaim her daughter’s inheritance. Su Wanwan uses her laboratory to provide her mother with better nutrition and medical care, improving their quality of life while keeping her abilities hidden by claiming an immortal taught her. The narrative follows their struggle against the patriarchal and greedy relatives who refuse to accept their loss of control. Su Wanwan’s cold, calculating demeanor contrasts with her mother’s protective warmth, creating a united front against the family’s continued attempts to undermine them. The story moves toward their eventual separation and the gradual exposure of the Su family’s true nature, as Su Wanwan prepares to use her medical knowledge to rise above her circumstances in the 1970s.
