"So, as you can see why I am serious about those abyss humans. I think they are targeting Livia. The more pure royal blood they will sacrifice, the more reward they will get from the demons."
After saying that, old man Perry stopped talking. But at this time you can say that Sam already guessed many things after hearing all of this. And he is definitely sure that mos t likely someone from this Kingdom approached those people and then previously told them the location of Livia.
Sam doesn't know if his guess was right or not, but it looks like old man Perry did not have any intention to tell him about this. Because of this he also did not ask him about this. Most likely this is related to the royal family and because of this, old man Perry did not want to reveal anything related to the royal family or something like that.
