Inside the dungeon, as you can see those Warriors who entered already begin to kill those Monsters one by one. As you can tell, compared to those Monsters, all of them were very powerful but still those Monsters made them surprised by their intelligence and the pattern of their attack. Even those Warriors never thought monsters like that would appear in a low grade gate like that.
Until now they have almost killed over 500 monsters. Also at this time they already became sure that they were present at the first floor of this house. Well this most likely the first time when they also face a surrounding area like that only showing them the environment of a house. The thing was that even if they wanted to get out the house they won't be able to do that as they cannot see the end of the house.
