Stockpile Food, Claim Land, and Rise from Farm Girl to Emperor

[Transmigrate into a book + fleeing famine + farming + special abilities + pocket dimension + female official + heroine becomes emperor] Tong Shu, who managed to thrive even in the apocalypse, suddenly transmigrates into an unfinished book and becomes a disposable character destined to have her whole family slaughtered and her blood drained. Fleeing famine from the start, with companions eyeing her greedily? Not enough food or water, and on the brink of starvation? Fortunately, Tong Shu's special abilities come with her, along with her pocket dimension and enough strength to flip a cow. Watch as she deals with these scumbags, changes the original plot in which her family was doomed to die, and avenges them all. She'll also work hard (with cheat powers every step of the way), become emperor, unify the realm, bring prosperity to the people, and become an emperor for the ages! Oh, and that young general seems pretty good too. She needs to choose excellent genes for the sake of her descendants, doesn't she?
