The location that Ben had given them was quite far inside the Desolate Plains of Gahana. While driving toward that location, Rein told Sophia and Ruby about Prucia and how she was actually a real intelligent monster. He also told them about how she and an amber of eternal fire inside her and how dangerous she could be. All this revelation made both Sophia and Ruby extremely surprised.
It was very understandable. According to what Rein said, this girl was a calamity that could destroy several nations without any problems. If her presence allowed the other monsters to leave the Desolate Plains without dying, then hundreds of not thousands of powerful monsters could attack the human cities. This would need many nations and their UR grades to team up together in order to solve it.
But for the time being, all three of them decided to not worry about it. All of them had confidence in their strength so even if what they were thinking happened, they would do their best to stop it.
