Daxia Zhijinwu

Modern engineer Chen Du travels through time and starts as a death row prisoner. Relying on the "Book of Construction" to deduce the fortification blueprints, he escaped death and was exiled to an isolated city in the north. The Great Xia Dynasty was in a state of decline, corruption was rampant, and border troubles were constant. Others wield swords to kill enemies, but he holds rulers and maps, builds strong cities, builds beacons, manages water transportation, and uses engineering skills to cope with troubled times. From being a prisoner under the rank to holding Jinwu in Daxia. A great pass is easy to build, but a human heart is hard to guard against. When the ten thousand-mile defense line was completed, the court's sword was quietly aimed at him.
