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

[A childless research genius and a lucky, beautiful doctor, a swapped marriage, love after marriage]

Jiang Wanwan transmigrates into an era-novel as a cannon-fodder character, a hapless woman who's just arrived and is already about to be buried alive as a sacrifice for a fool.

Her younger sister steals her marriage match? She turns around and takes her sister's supposedly "infertile" slacker fiance instead!

Staying alive comes first! But who could have guessed that this "slacker" husband would turn out to be a research genius in disguise?

From then on, with the genius by her side, she wants for nothing. But... wasn't he supposed to be infertile? Then what's this baby in her belly?!

Jiang Wanwan clutches her lower back and cries, "You liar!"

The genius readily admits his mistake and kisses her forehead. "Yes, it was my fault. Please calm down, my dear wife."
