Wen Yunhe, a 21st-century intangible cultural heritage blogger, transmigrates into the body of a tragic character in the novel "The General's Little Wife." She becomes the impoverished wife of He Mingzhang, a man who was drafted on their wedding day and presumed dead. The original owner of the body, also named Wen Yunhe, had devoted her life to the He family, working tirelessly to support her mother-in-law, brother-in-law He Mingjie, and sister-in-law He Mingyu after her husband's disappearance. Despite her sacrifices, she was exploited, abused, and ultimately driven to suicide upon receiving news of He Mingzhang's death. The transmigrated Wen Yunhe awakens moments after the original owner's suicide attempt, rescued by the He family who only saved her to preserve their free labor.
Upon integrating the original memories, Wen Yunhe discovers she has brought her modern courtyard and a spatial dimension with her. This space contains a spiritual spring that accelerates healing and a well-stocked supply of food, tools, and resources from her previous life. Recognizing the dangers that lie ahead—including impending war and the tragic fate of her biological family in the novel—she resolves to change her destiny. She confronts the He family, who demand she continue working despite her condition. When He Mingjie threatens divorce to force her compliance, Wen Yunhe refuses to be bullied. Her younger brother, Wen Yunqing, arrives and, moved by her suffering, carries her away from the He household to their family home.
At the Wen family residence, Wen Yunhe reunites with her blind mother and younger siblings. Using her spatial abilities, she improves their living conditions, hunting wild game and preparing nutritious meals that help heal her family's ailments. She learns that the He family is entitled to a military pension of eighty-two taels of silver and ten stones of rice due to He Mingzhang's rank. Rather than letting the He family keep this money, Wen Yunhe plans to claim it as her rightful share as the widow. She also discovers that the spiritual spring water can heal her mother's blindness and improve her siblings' health.
As she settles into her new life, Wen Yunhe faces continued harassment from the He family, who send He Mingyu to demand she return and help with the rice harvest. Wen Yunhe refuses, realizing that the He family only values her for her labor and dowry. She begins preparing for the upcoming chaos by harvesting rice at night using a modern grass-cutting machine from her space, secretly accumulating resources for the future. The story follows her journey from a submissive, exploited wife to an independent woman determined to protect her family and forge her own path, armed with the knowledge of the novel's plot and the advantages of her spatial golden finger.
