Lin Wanqiu was reborn and returned to 1966. She publicly canceled the marriage of her childhood sweetheart Gu Mingchuan, who had supported her for ten years, and took back all the tickets. Later she found out that she was pregnant with quadruplets, and the father of the children was He Changzheng, a tough guy soldier who had rescued her and had a crush on her for many years. Lin Wanqiu took the initiative to find He Changzheng, who had not yet set off on a dangerous mission, and the two registered for marriage and joined the army.
After joining the army, Lin Wanqiu opened the "Baicao Medical House" space and successfully saved high-risk quadruplets and successfully gave birth to them in an era of scarce supplies. Relying on her past life memory and space medicine skills, she was promoted from a military health worker to a maternal and child health expert, improving grassroots delivery and infant nutrition.
At the same time, Gu Mingchuan lost Lin Wanqiu's help after entering the city, and his life became worse and worse. When he learned that Lin Wanqiu married a meritorious officer, gave birth to four genius babies, and gained both fame and fortune, he felt filled with regret and begged for reconciliation, but was completely ignored by Lin Wanqiu. In the end, Lin Wanqiu gained a happy love, her four children grew into pillars of the country, and she also became a nationally recognized medical expert.
