Making a Fortune in the 70s with a Foodie System

Xia Ning'an, a 27-year-old film directing graduate student and food streamer, is transmigrationed into the body of a 17-year-old girl with the same name in 1974 rural China. The original owner died of despair after being forced to care for her injured fiancé, Lu Zecheng, a blind and legless soldier abandoned by his cruel adoptive family. Upon waking, Xia Ning'an discovers she has inherited a "Foodie System" and a parallel space resembling a modern farm resort. The system requires her to earn 100 million gold coins to return home, a goal achieved by selling food from her space to interdimensional buyers. She also receives compensation for the transmigration error, including an infinite material warehouse, a smart robot named Bond, five doses of gene optimization agent, and a powerful healing agent capable of curing ten people.

The core conflict begins immediately as Xia Ning'an decides to retrieve Lu Zecheng from the Lu family, despite her initial reluctance to marry a disabled man. Her father, Xia Changhai, a village accountant and veteran, supports the decision, viewing military service as honorable. At the Lu household, she witnesses the abuse Lu Zecheng suffered, having been locked in a firewood shed without care. Lu Zecheng, unaware of his adoptive mother Zhang Dahua's true nature, reveals he is not her biological son. He presents evidence of his adoption, including a longevity lock and an embroidered blanket, forcing the village head to mediate a separation. Lu Zecheng demands only his share of the military allowance he sent home over five years, refusing the house built with his money. The Xia family agrees to take him in, and he formally severs ties with the Lu family.

Back at the Xia residence, Xia Ning'an begins Lu Zecheng's recovery using the healing agent hidden in water, carefully pacing his treatment to avoid suspicion. She also utilizes the system to improve the family's quality of life, making soap and dishwashing liquid to replace harsh traditional alternatives. Recognizing the economic constraints of the era, she explores the local black market. Using items from her space, such as iron pots and army water bottles, she trades with female educated youths and black market managers. She accumulates cash, grain tickets, and industrial coupons, while also acquiring rare diamonds and a gold pocket watch from a disguised scholar selling his possessions for grain.

Xia Ning'an's actions transform the household dynamic. She cooks nutritious meals, including hairy crabs and fish, which the family enjoys for the first time in years. Her second brother, Xia Ninghao, and eldest brother, a soldier, become supportive of her efforts. She purchases a radio for Lu Zecheng to alleviate his isolation and provides the family with modern amenities like towels and toothbrushes. As she navigates the political and social landscape of 1974, she balances her secret system operations with her public role as a devoted fiancée. The story follows her strategic planning to build wealth through the black market and system trades while managing Lu Zecheng's gradual physical and emotional rehabilitation, setting the stage for her long-term goal of earning enough to return to her original world.
