Su Wanxing is a twenty-four-year-old web novelist living in a 23rd-century metropolis. Orphaned by a plane crash at age twenty, she inherited a vast fortune managed by her father’s loyal friend, Qin Bei. She lives a comfortable, isolated life dedicated to writing and studying traditional Chinese medicine and martial arts. Her existence changes when she experiences a hyper-realistic dream in which she transmigrates into the body of a fourteen-year-old girl with the same name in the Great Jing Dynasty. In this ancient rural setting, the girl is an orphan living with her two younger siblings, Su Wanyue and Su Wanfeng, under the cruel care of their paternal grandparents and uncles. The dream depicts a harrowing scene where the relatives attempt to sell four-year-old Wanyue to a broker to fund a cousin’s marriage, leaving the protagonist powerless to stop them due to her physical weakness.
Upon waking, Su Wanxing discovers that the "Intelligent Myriad Space" mentioned in the dream is real. The space is divided into a Modern Zone and an Ancient Zone. The Modern Zone features shelves that automatically refresh stocked items daily, while the Ancient Zone, initially locked, adapts to the environment of the ancient world. Realizing the dream may be a premonition of her future transmigration, Su Wanxing decides to prepare thoroughly. She liquidates her company shares through Qin Bei, converting her assets into gold and silver bars. She then engages in massive stockpiling, purchasing food, medicine, clothing, tools, and high-tech combat equipment. She also travels to M Country to purchase firearms and ammunition, defeating a treacherous arms dealer and looting a local armory to acquire heavy weaponry, which she stores in her space.
The transmigration occurs during a second air disaster on her return flight. Su Wanxing wakes up in the dilapidated courtyard of Su Family Hollow at the exact moment her dream ended. This time, she is not powerless. Using her martial arts training, she incapacitates her abusive relatives who are attempting to sell Wanyue. She demands the village head intervene and forces her relatives to sign a legal severance document, voluntarily giving up her parents' inheritance in exchange for complete independence and the return of her siblings' household registration to a deceased granduncle. She moves her siblings into the village ancestral hall, which is in disrepair but offers temporary shelter.
Inside the space, Su Wanxing discovers new developments. The Ancient Zone has unlocked, featuring a stone well with water that possesses healing and purifying properties. She uses this water to treat the scars and bruises on her body. She also learns that items transferred from the Modern Zone to the Ancient Zone change their packaging to match the historical period, allowing her to use modern goods without suspicion. To secure their future, she ventures into the deep mountains to gather medicinal herbs. There, she encounters a rare white wolf trapped in an iron snare and its injured mate with newborn pups. Using her medical supplies and the well water, she treats the wolves and feeds them cooked meat from her space. The white wolf shows gratitude, establishing a bond.
Su Wanxing takes the gathered herbs and premium wild ginseng to the county town. After being dismissed by an arrogant pharmacist, she sells her goods at a smaller, more reputable pharmacy for over two thousand taels of silver. With this capital, she purchases clothing, food, and household essentials. She also enlists the help of village elders, Grandpa Li Zheng and Aunt Li, to watch over the children and assist in finding property. She learns of a suitable brick-and-tile house with a courtyard and well for sale on the village outskirts. The story follows her transition from a desperate orphan to a capable provider, using her futuristic knowledge and space abilities to build a stable life for herself and her siblings while navigating the dangers and politics of ancient rural society.
