I Became the Villain's Wife in the Seventies

She transmigrates into a book set in the resource-scarce 1970s and becomes a 180-jin country girl?

No problem. She's got a golden finger.

She works hard and earns diligence points, then spends them freely in the shop.

Once she's got enough to eat, she makes sure to help her family prosper, too.

She mixes milk tea, fruit juice, and other drinks, then trades them for cash on the black market.

She makes hair ornaments out of fabric scraps and sells them on the black market, earning her sister-in-law some pocket money.

Her white-lotus neighbor is jealous that she married a powerful man and tries to smear her?

She fights back with sweetly barbed words, using the childhood sweetheart's own tactics against her and leaving her with nowhere to turn. She even sends her off for a little stay at the Public Security Bureau.

The reborn female lead doesn't want her to live well and tries to set a trap for her?

She turns the tables and makes the other woman lose everything!
