Su Di, a fabulously wealthy heiress, was chosen by a book spirit and transmigrated into a bawdy novel set in the 1970s. She was told she had to change the story's course and restore its proper values and moral outlook before she could return to the real world.
She thought she would become the heroine, but instead Su Di landed in the body of a hapless girl with a tragic background who had just been beaten to death by her own family.
Su Di: “…That's a nice rope. Perfect for hanging myself.”
The bawdy book: “Ancestor, put down the rope! I'll give you a golden finger. I'll give you everything I have! Di, don't go!”
Su Di valued her life, and with her golden finger, she knew she could make a decent life for herself anywhere.
Her wicked father and grandmother wanted to steal the job the hapless girl had earned at the cost of her life, so Su Di promptly sold it.
They wanted to marry the girl off to a blind, ugly cripple, so Su Di went straight to his house. “Let's see what kind of family dares to marry me.”
The hapless girl turned out not to be the wicked couple's biological daughter. Su Di smiled. “No problem. I'll make you send me back yourselves.”
…
Then one day, someone suddenly appeared in her golden finger's pocket dimension. Su Di looked up in shock. “How could it be Qi Jin?!”
Since he was already here, there were a hundred mu of land in the dimension with no one to farm it, and the cows still needed milking. She'd leave it all to Qi Jin.
The bawdy book: “Ever since Qi Jin arrived, I haven't had to work like an ox anymore. I'm so clever.”
The male lead's perspective: Years of unrequited love finally come true.
The male lead appears fairly late in the story!
