"As usual, every time a new dungeon appears, this kind of thing will happen. It would be good if Sam was able to find out about that strange energy.
Every year, somehow, those monsters get affected by those strange energies, and they will get the power to break out of the dungeon. Previously, we had already tried to bring out monsters outside the dungeon. Unfortunately, all those monsters did not survive outside the engine.
But I am definitely sure, because of that strange energy, those monsters could survive outside the dungeon."
"Hmm… you are right. If we get to know how to counterattack or destroy the connection of that strange energy, then I don't think any of the monsters will be able to come out of the dungeon.
Unfortunately, even though we had already tried to search for that strange energy and the reason for those monsters getting the ability to go outside, we did not find anything.
