Allen was right now checking the map and thinking which place he should go for the next dungeon. Well as you can tell after clearing the previous dungeon he did not create any other than and because of that right now he had many places that could turn into dungeons. Naturally he will only choose the best place for him and after looking at the map for sometime he already decided to choose the small forest.
Actually inside the white tiger Academy many places like that present. So he decided to choose a small forest and instantly as you can tell a Dungeon appear in his system and the name of the Dungeon was,
"Forest dungeon (level 50 to level 55)
[You should be careful of these dungeons. Who knows which type of Monster you will face and how powerful was those Monsters.]"
