The Fertile Army Wife Returns to the Seventies: Her Cold Commander Has Three Babies in a Year

[Infertile army commander + transmigrated special agent + swapped marriage + love after marriage + medical skills] Shen Shiyun transmigrated and became an adopted daughter of the Shen family in the 1970s. As soon as she arrived, the real daughter, Shen Lingling, who had been reborn, switched their marriage prospects. She heard her intended was a regiment commander, perfect in every way except that he couldn't have children. Shen Shiyun happily married him. She was a special agent from the twenty-first century. Curing a man's problem in that department would be a piece of cake. Besides, she was highly fertile. After they married, Shen Shiyun spent every night holding her aching waist. One day, Gu Cheng'an returned from leave and was feeding the four little ones at home when Shen Shiyun suddenly threw up. She glared at him furiously and ground out, “I'm going to sleep in a separate room from you!” Gu Cheng'an could only coax her and beg for mercy again and again. Meanwhile, Shen Lingling, who had stolen Shen Shiyun's husband from her previous life, was living through hell. Wasn't it supposed to be that educated youths who became high-ranking officials would enjoy smooth careers? How had he been dismissed after only a few days in office, with no chance of making a comeback? By then, Gu Cheng'an had been promoted again, and his and Shen Shiyun's fifth child had just been born. The fabulously wealthy Gu family announced that they would give half their fortune to their great benefactor, Shen Shiyun. When Shen Lingling heard the news, her eyes reddened with rage! Why? Why was Shen Shiyun so lucky?
