In the Sixties, I Earned Foreign Currency for My Country

(Period setting + farming + food + strong female lead + 1v1)

Zhen Zhen accidentally transmigrates to the 1960s. She expects life to be hard, but thanks to her family's hard work, their days grow more and more comfortable.

Just when she thinks she'll go on living happily and peacefully, she discovers she's transmigrated into a farming and leveling game.

And she's merely a character not even worth mentioning in the game: the female lead's cousin, a supporting character.

Realizing she's on the villainess side, she decides to keep her distance from the female lead, lest she get splattered with blood when the heroine makes her move.

She also advises her cousin, another supporting character, to stay out of the leads' disputes.

After all, the heroine is a transmigrator from ancient times to the modern era, a master of household intrigue who knows how to stir things up.

But later, Zhen Zhen realizes that things are getting stranger and stranger.

The heroine isn't truly kind and virtuous, while her cousin turns out to be a blunt, guileless fool.

The heroine is completely steamrolling her!

That won't do. Zhen Zhen is fiercely protective of her own.

Besides, the heroine has started picking on her side, too.

Her rule has always been: If you leave me alone, I'll leave you alone. If you mess with me, I'll hit back.
