Standing around one of the sewage work sites, Alexander easily noticed the hustle and bustle of the work, as workers moved with speed and urgency to and fro through the many small doors which were the entrances of the city's bowels.
The ones going carried a variety of materials inside, ranging from building materials such as stone, bricks, cement, and even wood, to food and drinks for the workers inside, to lastly firewood for the braizer that worked to illuminate the place.
All these were usually carried in large wooden buckets they carried on both hands or sometimes more curiously in cast iron metal pans that the workers placed on their heads
Alexander had noticed it before too, but it seemed that due to the abundance of iron, many construction sites were starting to substitute bronze tools for iron.
Anyway, this traffic was not only one way.
Because there were workers coming out of the tunnels too, though their accompanying material was much more simple.
