Kyle looked around the city some more.
'Buildings,' he thought. 'Normal buildings.'
Sure, the buildings were old, but they didn't seem very different from any other kind of building.
They had roofs and walls.
Most of them were constructed out of old wood, stone, and some metals.
'Wait a second. Wood?' Kyle thought.
Kyle looked around the walls of the cave and saw some chunks of iron and copper.
Metal Elementals were not really interested in such low-level metals since they barely had any Ether.
When Kyle looked at the buildings again, he saw some parts made of iron and steel.
After that, he looked at the surroundings of the cave.
There were some tunnels, but they were all made recently, most likely by Metal Elementals.
'Why the fuck would you use wood in an underground city? You obviously know how to make steel, and there's a bunch of iron. Why go through the trouble of getting wood from the surface?'
At that moment, Kyle had a thought.
