Shen Jingyu, a female PhD in architecture, suddenly transmigrates into a princess consort who has just married and is immediately caught up in her family's confiscation and exile. With no system or pocket dimension, she faces the harsh winds, sandstorms, and miasma of Lingnan, while her husband, a legendary god of war, has had the tendons in his hands severed and both legs crippled. Her younger sister, the apple of the family's eye, knew what was coming and broke off her engagement to marry the Crown Prince, escaping the disaster. Everyone expects Shen Jingyu to perish in the wilderness. Fortunately, her mind holds thousands of years of infrastructure knowledge, blueprints, and industrial formulas. She makes bricks, builds canals, smelts iron, manufactures crossbows, clears wasteland, and cultivates fields, transforming a desolate place of exile into fertile land. At first, her husband thinks she is merely indulging in wild fantasies. But after recovering, he takes up his sword to protect her: You build the city; I shall protect the realm. When chaos engulfs the land, the Crown Prince and her younger sister flee, only to discover that the once-barren wilderness has become an impregnable steel fortress.
