Exiled into a Phoenix: the Infrastructure Queen and the Downtrodden Prince

From a prisoner in purgatory to the founder of a prosperous age; from a deposed prince to the co-ruler of the world. This is a desperate counterattack that spans time and space, and is also an epic about infrastructure, power, and immortal affection. Modern engineer Lin Wan was transformed into an exiled prisoner. He was on the verge of death at the beginning, with the abandoned prince Xiao Yan lying next to him with festering wounds. In the ice wilderness, she used her knowledge to survive: identifying wild vegetables, making water purification, and treating serious injuries. With wisdom beyond the times, she established absolute authority in the exile team. Arriving at the bitter cold border town, everyone accepted their fate, but Lin Wan wrote to paint a new sky. Improving farm tools, innovating mine tunnels, promoting work points, and building blast furnaces... She used modern thinking to set off a technological revolution, turning the barbaric land into a miracle city where everyone can live. Xiao Yan went from watching with cold eyes to being devoted to each other, and his silent ambition was burned again because of her. He holds the sword to guard her blueprint, and she builds his empire with machines. She created a prosperous age for him, but she was forever absent from this prosperous age. He no longer established a queen for the rest of his life, and history books only lamented the emperor's infatuation. Little did he know that what he lost was the one who used modern wisdom to win the entire era for him - the Queen of Infrastructure.
