Civil engineer Shen Zhou, his soul passed through the turbulent Great Xia Dynasty, and became the useless governor of Heishidu, the most barren place in the Northern Plains. Facing the coming genocide and the anger of the refugees, he has no system or space in his hands, only a head full of modern engineering knowledge. While the dignitaries were drunk and dreaming in the capital, Shen Zhou burned the first batch of cement in the cold wind of Beiyuan with the crudest furnace. When the enemy's cavalry broke through the border, Shen Zhou shocked the world with the steel defense line he built. This is a story about using steel bars, concrete and the laws of physics to create a prosperous age in a decadent apocalyptic dynasty.
