The 1970s: A Childless Research Genius, and I Gave Him Twins

[A Sterile Research Genius VS A Beautiful Doctor Who Brings Good Fortune and Fertility, Swapped Marriages + Love After Marriage]

Jiang Wanwan transmigrates into a cannon-fodder character in a period novel, arriving just in time to become the unlucky girl who has to be buried alive with a fool.

Her younger sister steals her match? She turns around and takes over her sister's lazy fiancé, the one said to be sterile!

Staying alive is what matters! Who knew her "lazy" husband would turn out to have an astonishing secret identity: he's a hidden research genius!

With the genius husband by her side, she never has to worry about food or clothes. But... wasn't he supposed to be sterile? What's this baby in her belly?!

Jiang Wanwan clutches her back and protests: "You liar!"

The genius has mastered the art of apologizing. He kisses her forehead. "Yes, my fault. Please calm down, my dear wife."
