After I Transmigrate into a Book, I Become the Richest Man in Exile

[Transmigrate into a book, spatial storage, mind-reading, exile] A special forces doctor transmigrates into the body of a vicious cannon-fodder princess. With the whole household about to be exiled, she ransacks the estate and loots the imperial treasury to stay alive. Everyone in the household becomes her devoted sidekick. Her father, the prince, secretly listens to her thoughts every day, convinced she is possessed by a fox spirit and constantly afraid she'll give away their plans. One day, Gao Tongtong realizes: [Why is everyone reborn except me?] Fine, so that's how we're playing it?
