I Became a Villainess's Wife in the 1970S, and I Married a Retired Soldier

I transmigrated into a book set in the resource-strapped 1970s and became a 180-jin village girl from the countryside? No problem. I have a golden finger. Work hard and endure hardship to earn diligence points, then spend them freely in the shop. Once I’ve fed myself, I’ll make sure my family prospers too. Mix up milk tea, fruit juice, and other drinks, then sell them on the black market for cash. Make flower hair clips out of scraps of cloth, then sell them on the black market to earn my sister-in-law some pocket money. The white-lotus neighbor is jealous that I married a big shot and tries to smear me? I’ll beat her at her own game, using her childhood sweetheart’s tricks to leave her with nowhere to turn, then send her off for a few days’ sightseeing at the Public Security Bureau. The reborn female lead doesn’t want me to have a good life and tries to set a trap for me? I’ll play along and make her lose everything she has!
