The second prince’s sincerity (3)

The next destination that we headed to was…a quarry.

This wasn't just any quarry, it turned out to be a quarry that was filled with a special material.

Limestone.

This was a limestone quarry.

As soon as I saw this, there were things that were suddenly made clear to me.

When we were in the village, there was something else that I had noted.

The buildings that were in the village weren't just the normal stone and wood buildings that could be seen everywhere else. The buildings in that village were like stone buildings, but the material seemed different.

The fourth prince didn't really pay attention to this since he didn't know what this material was in the first place.

However, it was different for me who had come from a more modern world.

The moment that I saw it, I recognized it.

It was concrete that was used to make these houses.

Though I had no idea what that concrete was made from until I saw this mine.
