The first proof of the printing press

During the afternoon, Einar, who was on the outskirts of the village, looked serious as a group of slaves was working on the drain.

These used red partitions which were stacked forming a tunnel whose upper shape was arched.

Einar hadn't wanted the sewer tunnel to be too big, so it was barely one meter high, eight inches long, and one meter fifty wide.

This he did so that if an enemy wanted to infiltrate, they could not have so much room to maneuver so it would simply be enough to open one of the valves that were connected to the different hot springs so that the sewers were filled with hot water.

Ensuring that any enemy would be drowned.

Another thing that he also noticed was that the fire pit system was being implemented correctly since wherever cement was being used they were present.

Einar with his arms crossed looking at all the workers and slaves present.
