Nightmare has arrived

Leo felt uneasy as he sensed the environment around him. 

This feeling was like going into an exam without having studied at all or realizing that school starts tomorrow and you haven't completed any of your homework. 

In any case, it was a very uncomfortable feeling.

Leo frowned and said, "You all need to focus. 

There's something strange about this place; it seems like Devil Race has occupied it, although I'm not quite sure how they invaded the instance dungeon."

Instance dungeons are not like public places; they have corresponding instances for each player, meaning every player can experience a brand-new and completely different dungeon. 

Under these circumstances, it's nearly impossible for Devil Race to invade instance dungeons.

After all, the Devil Race has limited numbers; they can't possibly infiltrate every instance dungeon, right?

So Leo found this a bit strange since his knowledge of the Devil Race wasn't extensive.
