A Female Agent Opens Her Eyes in the Seventies and Hits the Ground Running

[Historical Era + Sent Down to the Countryside + Powerful Face-Slapping + Pocket Dimension + Deliberately Switched at Birth + Family Life + Refuses to Take Abuse + Female-Oriented Feel-Good Story] Su Wan, an elite mercenary from the 25th century, opens her eyes to find herself in 1973, in the body of another Su Wan, who shares her name. The original Su Wan was deliberately switched at birth. When she returned to the Su family, she thought her suffering was finally over, but it was only the beginning of her bad luck. Her parents took her back because they didn't want Su Tang, the girl they'd raised, to marry the crippled man she'd been promised to as a child. The man she'd been promised to never came to propose, and the Su family feared she'd be a freeloader, so they signed her up to be sent to the countryside. During the half-month since she'd returned to the Su family, the original Su Wan had been stuck doing every dirty, exhausting job. After taking in all the memories, Su Wan realizes the original really was a walking disaster. But since she's here now, she'll avenge her. First, she'll deal with her mother and that white lotus. Wait, the white lotus is the scumbag father's child with another woman? Now there's work to do. She turns the Su household upside down, signs up her two brothers and the white lotus to be sent to the countryside, and clears out the entire family fortune. Once in the countryside, she torments the most awful educated youths with one hand and catches enemy spies to earn merit with the other. When she has nothing to do, she heads up the mountain to catch a wild boar for a snack. With her fighting skills and medical expertise, she thrives in the countryside. Wait, what's with the man she casually rescued? Why does he keep trying to get her attention? Su Wan: "Hey! Don't you have anything better to do?" The man gives a light cough. "A little. Let's talk." Su Wan rolls her eyes. "I'm busy." The man smiles and strokes his chin. "I heard you like men with eight-pack abs?" Su Wan: "What's it to you? It's not like you have them." The man grins mischievously. "Come on! I'll show you!"
