There was no system or golden fingers, and all he relied on was the rough skills of ten years of traveling to construction sites. He looked at the soil to find water, recognized the grass to fill his stomach, used stones and weeds to filter water and build defenses, and relied on the terrain to avoid the insurgents.

In this age when human life was less than grass, they used their hands to dig out a way out of the ruins and became a stronghold in the troubled times!
