Dungeon Core 563 was the leader of this group of S Rank Adventurers, so his reaction was something that everyone noticed since he was the center of attention at this moment.
When everyone saw him knit his brows all of a sudden, they couldn't help asking in concerned voices, "Is something wrong?"
Dungeon Core 563 didn't seem to care about what they said as he looked around with the same frown on his face, but it only grew as he couldn't find what he was looking for.
This was a voice that had spoken right into his mind, so he knew that whoever it was that spoke to him just now wouldn't be a normal person. As such, he had been using the different methods that were available to him to search for any other kind of method that could have been used.
But even then, Dungeon Core 563 couldn't find anything which was why he had this frown on his face.
"Just give up, you'll never be able to find me."
