They had built the wall. It wasn't easy—it took time—and only after a year and a half had it been completed.
Only one thin layer of stone with some sticky white paste the people of this world used instead of cement to bind the stones. A thin layer was on both sides, and in the middle was a wide, wooden interlocking, deeply buried wall. One person could climb above it and walk freely.
The villagers had no other ideas, so they had instantly agreed to give a try to his game-making plan. There wasn't much to invest other than a little free time in the evening for the blue-rank summoners and some carpenters. An empty warehouse near the village square was used by them, and every evening, after finishing up their work, all the needed parties gathered. They had six blue-rank wood summoners, so Auren only called two for twice a week, and the two carpenters had agreed to help, dividing a three-three day workload.
