After I Transmigrated Into a Book, the Cannon Fodder Supporting Actress Fights Back

[Transmigration into a book, cannon fodder, comeback, feel-good story] After posting a furious long review, Yu Rushuang transmigrates into a book as a character with the same name: the Marquis's third legitimate daughter. From the start, she's thrown into a sex scene. But with no fighting skills, she can't escape, so she has no choice but to run first and figure out the rest later.

As her fate begins to change, Yu Rushuang gets a “good luck” System. No, wait, what's this about adding fertility luck? Having one child is already more than enough! And what about that man who's slowly getting closer? Didn't he say that if she dared to set him up, he'd make her regret it? So why is he clinging to her now?

Feng Mingjin leans closer. “My beloved, good fortune with children is here. We can't let it go to waste.”
