Transmigrate into a Book Set in the Seventies, Save the Cannon Fodder, and Enjoy the Gossip

Killer Lin Guanyue transmigrates into a book as the daughter of a capitalist family, only to become a cannon-fodder character. Her scumbag father and wicked stepmother are heartless, while her fiancé hooks up with her stepsister. If she's going to have a miserable time, then they can all head to the countryside and help build the motherland!

While everyone else suffers in the countryside, Lin Guanyue keeps getting supplies in endless waves.

Then one day, a handsome young officer shows up and acts like he's determined to stick by her side.

Lin Guanyue has a headache. Why won't the original story's hero and heroine follow the script?
