Capítulo 166: 166. Blind Swamp Monster.

Dungeons and labyrinths in this world were a bit different from the ones Orion had read about in the novels from his previous world.

'The dungeons in this world were of different ranks,' He uttered in his thoughts.

'And each dungeon's rank had a specific terrain and group of monsters that was unique to it, but different from other dungeon ranks in the world.'

'For example, an F-rank dungeon may look like a cave that houses monsters like goblins and slimes. However, an E-rank dungeon won't look the same as an F-rank dungeon.'

'On the outside, the dungeons might look alike, but once an adventurer steps into it, a magic circle would appear, and he would find himself in a magical forest containing wolves, wild boars, and some other monsters.'

'Also, Mom said an F-Rank dungeon in the elf kingdom is different from an F-Rank dungeon in any other kingdom.'
