The Villain Daughter Wanted to Survive, but Became the Queen of the North

[First person + villain daughter + light lily + western fantasy alchemy + territory construction + light comedy] When she was five years old, Nora, the daughter of a duke, remembered that she was the villainous daughter in a novel. In the original work, at the age of sixteen, she would die at the hands of her fiancé, the prince, for framing the saint. In order to survive, Nora began to study magic and alchemy - the first experiment left the Duke's Palace missing a window. Eleven years later, the saint awakened as scheduled. Nora skipped school and marriage all night and hid in the northern border, which was poor, cold and plundered by demons every year. She just wants to escape the death penalty in the original work, but the people in the north may not even be able to survive this winter. So Nora was responsible for blasting out the alchemy prototypes one by one, and the people from the North were responsible for making them truly usable. Later, the magical greenhouse covered the snowfield, and the people who were once afraid of the demons entering the village began to chase the demons to collect alchemy materials. Nora: "Why do they call me Queen of the North? Does this count as treason under the laws of the kingdom?" What's even more troublesome is that the saint who was supposed to fall in love with the prince also chased him all the way to the north.
