It was rumored that the Grey Beastmen weren't natives of the Raging Flame Plane. Their ancestors were from another place, but by now the Grey Beastmen had been living in the Raging Flame Plane for countless years. After having developed to this point, even the other Beastman races of the Raging Flame Plane didn't feel that they were outsiders.
As for their fort, it was clearly inconsistent with the style of other Beastman races. It was a neat and tidy rectangular prism.
From a distance, it looked like the city walls had been cut from a huge grey rock. Metallic luster could be seen flickering on the walls, and wisps of mana fluctuations could be felt, even from several kilometers away.
Lin Yun couldn't help being somewhat amazed. He didn't know what material had been used to make the city walls, but the outside was covered with a layer of forged magic metal.
