"Well, you know arcane arrays better than all of us here, Mr. Sullen!" Gustav said. They knew nothing about arcane arrays, so they couldn't possibly detect spiritual energy waves like that. Jacob stopped talking and carefully observed the building in front of him.
Given how lavish the surrounding architecture is, it doesn't make sense for the count to leave this house unrenovated. As old and worn-down as this house may seem, it would still cost a lot of spirit coins to build. If the count stays here and is keeping it the way it was, then it must be something special to them!
Jacob was snapped out of his train of thought when the door opened all of a sudden. Hester then stepped out of the house and said, "The count welcomes you all inside." Nodding, Jacob proceeded to lead the group into the house. They were all feeling excited and curious as to what kind of person the count would turn out to be.
