Exiled, She Goes on a Rampage with Trillions in Supplies

[Exile + nation-building + farming with a golden finger + a fearsome demon king who's both gentle and fierce VS a sickly, obsessive antagonist] Hua You, unconscious from poisoning, transmigrates into another world. When she opens her eyes again, she's back, but her home is gone. The dog emperor wants to confiscate her entire household's estate and take her military power? Hua You retaliates by using her golden finger to take away the wealth her family has amassed over hundreds of years. She'll show him what it means to lose both people and wealth. Her place of exile has been changed from Ningguta to Qiongzhou, a desolate land of mountains and rivers? As the young and old in her household worry about the future, Hua You sneers. Desolate land? She can turn even a barren wasteland into paradise. Faced with a lack of food and clothing, extreme weather, cruel soldiers, and assassination attempts by the court on the journey into exile, she looks at the endless supplies in her pocket dimension and rolls up her sleeves. It's time to show what she can really do. She promotes farming, builds infrastructure, opens sea routes, and expands trade... Just as she turns the desolate land into the greatest city in the world, the sickly man behind her approaches, smiling gently, a chain in his hand...
