Late Ming Dynasty: Base Construction System

At the end of the Ming Dynasty, the countdown to the country's subjugation began. Traveling through five hundred miles of barren mountains and ridges in Gyeonggi Province, you will awaken the base construction system. Build houses, open up wasteland, improve technology, and build guns. The Chuang army came eastward, the Eight Banners moved southward, and the Ming Dynasty collapsed. Everyone in the world is struggling to survive in troubled times, but I built a steel city at the foot of the Taihang Mountains! The destiny of China will be rewritten by me from now on.
