I Transmigrate into a Book During a Natural Disaster, but No Worries, I've Got a Golden Finger

Hu Qianqian transmigrated, and not only that, she transmigrated into a book! She quickly pieced together the entire plot of this melodramatic novel about a doomed supporting character in the Duke's household. Then she rapidly worked out how she should navigate the life ahead of her. Transmigrate → become a widow → discover her golden finger → be exiled → face the challenges along the way → reach the place of exile → start a business → reunite with her dead husband → face extreme weather all over again!
