In 2035, Ling Xi, a national treasure-level scientific research and weapons genius, died in a major experimental accident, and his soul traveled back to 1970 to an educated youth of the same name who had just been pushed into the water and drowned by his fake best friend. After waking up, she faced an era of scarcity of materials but passionate family love. Her father is the captain of the production team, and her mother is a crazy protector of girls.

She originally wanted to keep a low profile and build a strong country through scientific research, but she accidentally became the center of the family's pet. In the process of avenging a scumbag, leading her family and the village to wealth, and silently contributing to the country's technological progress, she began a love and marriage that was evenly matched, warm and healing, and her brother-in-arms Zhou Rui, who rescued her ashore and was a soldier king with an extraordinary background.
