In the Last Days of Silent Desolation, I Will Build a Sacred Wall of Thousands of Miles to Protect All Races.

Eternal desolation, everlasting night, rampant shadows, the powerful monopolizing resources regard the refugees as ants. Lin Yan, a civil engineer who traveled through time and became an abandoned son of his family, activated the boundary-building system. He used fortifications to build barriers and city walls to suppress evil spirits without relying on his bloodline. Lay traps, build high walls, erect divine cannons, build the Great Wall, resist shadow erosion, resist nobles, defend against predators from outside the territory, protect thousands of refugees and alien creatures, and reshape the order of heaven and earth with your own hands!
