I Transmigrated into a Book Set in the 1970s. Before My Disabled Husband Died, I Helped the Whole Village Get Rich

Shen Ning transmigrates into a book set in the 1970s as a disposable character who doesn't survive past chapter three. Her father died in service, her mother is mentally ill, her aunt's family has taken over their home, and she's being forced to marry a disabled soldier. But Shen Ning doesn't panic. She heals his leg, puts the villains in their place, and makes money hand over fist, leaving her aunt's family so jealous their eyes turn red.
