Damien somewhat expected it after seeing the man's attitude, but Karlen himself was the one who gave the tour.
The Temple's Right Hand was an extremely notorious figure. There wasn't a person on this island who didn't know his face.
So, seeing him act as a tour guide for a mysterious man was definitely a strange experience for the people of the Earth Temple.
They went from top to bottom. Most floors were used only for housing, so the tour didn't take very long. There were many facilities on the higher floors that would be helpful to any practitioner who wanted to train, but they were nothing different from the norm.
Nevertheless, the tour did a good job raising Damien's fame. In the coming days before the tournament began, he'd likely have to do a lot more to secure himself the spot he was promised.
After all, no matter what happened, it was too suspicious for the single real tournament spot to be given to a new member.
