Ruan Tong, a skilled surgeon from the modern era, wakes up in a bridal chamber in 1986, having transmigrated into the body of a twenty-year-old village girl who had just married Gu Bai. The original host was known for her reckless behavior and had resisted the arranged marriage, but Ruan Tong quickly adapts to her new reality. She discovers she possesses a mysterious spatial dimension containing a fully stocked laboratory with inexhaustible medical supplies, a powerful asset in an era of scarce resources. Her new husband, Gu Bai, is the fourth son of the Gu family, a former soldier who retired with a severe leg injury after his team leader died in action. He is now responsible for raising his late commander’s two young children, Dabao and Erbao, while living with his extended family in Luoxia Village.
The core conflict arises from the tension between Ruan Tong’s modern medical expertise and the primitive healthcare conditions of the 1980s countryside. When Erbao suffers a life-threatening febrile seizure, Ruan Tong uses ibuprofen from her Space to save him, earning the gratitude of her mother-in-law, Wu Minzhen, but also drawing the suspicion and hostility of her sister-in-law, Xu Yan, and the younger sister-in-law, Gu Qin. Xu Yan, who once harbored feelings for Gu Bai, views Ruan Tong as a rival and actively works to undermine her, spreading rumors and creating domestic strife. Despite these challenges, Ruan Tong steadily wins over the family by treating illnesses with her advanced knowledge and medicines from her Space, gradually shifting from an unwelcome outsider to a respected member of the household.
A key turning point occurs when Gu Bai’s leg injury flares up after a trip to town. Ruan Tong insists on treating him, using acupuncture and modern medical techniques from her Space. Although Gu Bai is initially skeptical and guarded due to his past traumas and physical limitations, he begins to see Ruan Tong’s sincerity and competence. Their relationship evolves from distant cohabitation to a partnership, with Gu Bai offering financial support and protection while Ruan Tong provides medical care and emotional stability. She also successfully bonds with the children, particularly Dabao, who initially resents her as a stepmother but eventually accepts her through patient and kind interactions.
The story takes another significant turn with the arrival of Qiuhong, a cultural soldier from Gu Bai’s military past whom Gu Qin idolizes and believes is his true love. Qiuhong’s visit threatens to disrupt the fragile peace Ruan Tong has built, as she attempts to rekindle a relationship with Gu Bai. However, Ruan Tong asserts her position confidently, displaying jealousy and ownership that surprises Gu Bai. Meanwhile, Ruan Tong discovers she is pregnant, adding a new layer of complexity to her life in this era. The narrative follows her efforts to navigate family politics, manage her secret Space, and build a future with Gu Bai, who is slowly opening up to the possibility of happiness after years of grief and isolation. The story highlights Ruan Tong’s determination to improve her circumstances and her family’s well-being using her unique advantages, while dealing with the ongoing challenges posed by jealous relatives and the limitations of their rural environment.
