Su Wanqing time-travels into a period novel written by her cousin, becoming the cannon-fodder former wife destined to be forced into a substitute marriage with the injured rescue team captain Zhou Yanshen and to suffer in the countryside. Relying on her real-life traditional Chinese medicine skills and the preemptively activated "Myriad Phenomena Rubik's Cube" space, she takes back her salary and grain booklet, stockpiles goods to take to the countryside, saves people and cures illnesses, and gradually changes the tragic fate of herself and Zhou Yanshen's family in the original book. Revolving around post-marriage sweet pampering, battling obnoxious relatives, spatial stockpiling, and life in the Northwest land reclamation team in the countryside, the female protagonist stands firm in adversity through medical skills and golden fingers.
