Su Qing, a modern city planner, is dressed as the daughter of a convicted minor official in ancient times and lives in a run-down border town. Refugees are everywhere and the city walls are crumbling. She has no system or magic. She only has a head full of knowledge about property valuation, land planning and infrastructure. Starting from renovating dilapidated buildings and designing drainage, she unexpectedly embarked on a unique "farming" path - not to grow food, but to "plant" cities. She planned neighborhoods with the idea of developing new areas, resettled refugees with the concept of building housing projects, turned wasteland at the frontier into a business hub, and turned war fronts into steel homes. When the blueprint of the "ideal city-state" she drew eventually became the towering Great Wall that protected the people of the country, the entire era was shocked to realize that what this woman built was not only a masonry city wall, but also the backbone of a nation rising from the ruins.
