20th Floor.
As soon as they touched this place, a strange cold mixed with a strange heat hit them.
They were in one of the Cities of the 20th Floor, the City of Entrance. This entire city was built on a mountain with a large protective wall.
At the same time, above the city was a concrete roof with protective magic to prevent solar pellets from falling on the city.
This also prevented the wind, created by huge fans that ventilated the city to keep it cool, from escaping its walls.
As soon as Louis set foot in this place, he felt the heat coming from the depths of the earth and the curious cold from the huge fans.
'How curious,' he thought.
