I Transmigrated into an Exiled Noble Consort and Took Off Through Infrastructure

[Transmigration and exile + no System, pure infrastructure-building + fighting back from desperate odds + evenly matched leads + strong female lead] Shen Jingyu, a female PhD in architecture, transmigrated into the body of an unlucky princess who had just married into the family, only to have her household confiscated and be sent into exile. She had no portable dimension and no sign-in System, only endless sandstorms along the thousand-mile road into exile, and at her side, a famed war god of a husband with crippled legs and severed tendons in his wrists. Her foil was her younger sister, the beloved woman who had heard of the impending disaster early and broken off her engagement in advance to marry the Crown Prince. Everyone was waiting to see the once-famous young lady die in Lingnan's miasma. Looking at the desolate land and the crowd of elderly, weak, sick, and disabled people, Shen Jingyu rolled up her sleeves. “I may not have a portable dimension, but I have five thousand years of infrastructure plans and heavy-industry formulas in my head!” Improving farm tools, firing bricks and tiles, building waterworks, smelting steel... Bandits came to rob them? No problem. She hand-built a repeating crossbow overnight, taught the bandits a lesson, and recruited them as construction foremen. No food to last the winter? She led the way in clearing land, planting crops, and improving the soil, turning barren country into a paradise beyond the frontier. At first, her disabled husband thought she was crazy. Later, he silently walked on his healed legs and stood before her with his sword drawn. “You just focus on building your city. I'll conquer this world for you and keep it safe.” Years later, the empire fell into chaos. The Crown Prince and his beloved fled in a panic, only to be stunned to discover that the supposedly barbaric place of exile had long since become an impregnable city of steel. And the cripple they had abandoned was now looking down on the world, his arm around the city lord's wife, whose wealth rivaled that of an empire.
