Kairos stopped in place and looked up with wide eyes.
"...What?"
They were still in the city, but there was a wall far up ahead in sight. It was a mixture of gray and brown while the wall itself was incomparably smooth. The walls encapsulated quite a large area, so much so that Kairos couldn't actually make out the end of the walls easily. As for the height, it should've been at the very least thirty meters high.
Surrounding these walls were various collapsed buildings. This created quite a large clearing surrounding the place, which made it stand out even more than it already did.
In a certain sense, it appeared as though it had just plopped itself down, and destroyed everything nearby. Basically, it just felt unnatural.
This made Kairos feel a little strange about this place.
He couldn't help but think this wasn't something humans constructed, thus he thought that it may have been some sort of natural phenomenon that was potentially dangerous.
