Main character: Lin Shuang
[1970s setting + transmigration + nonviolent noncooperation]
In the modern world, Lin Shuang was an ordinary boxing coach who just got by, living on her own with no one else to feed. One day, she transmigrates into the role of a fool's wife in a period novel. Her birth family, eager to get rid of a burden, half-sells her off and throws her out, while her husband's family treats her like a punching bag. Everyone around her is a villain.
But she's not afraid. When it comes to throwing punches, they've already killed her once. She'll go mad right where she stands. Dock my work points? Cry, make a scene, and threaten to hang myself? That's old-fashioned. One isn't enough, so I'll hang several of them.
If my brother-in-law wants to sponge off the family like a leech, I'll drag his face through the dirt.
While getting revenge, she doesn't forget to build her fortune. She's landed in an era when even pigs can fly if they catch the right wind. How can she not take advantage?
[PS: The heroine is a little unhinged. She'll eat anything except a loss, and she has no morals.]
