Soul Chamber
The details about the origin of summoning magic made Adrian glad because that means that his job class is special. It would also mean that it is highly unlikely for another summoner to be the same as him. Some job classes are basically just offshoots of the base class with just different specializations.
"What I am really curious is the Soul Chamber? How would I be able to go inside it?" Adrian muttered but Pann finally answered him.
"You should be able to easily visualize it because you have been in your subconscious before. Except this time, you would enter in another door because the Soul Chamber is located at the magic circle that is carved in your heart." Pann stated.
"I see. Thanks for the tip old man" Adrian stated as he waved Pann goodbye, but the latter was not finished with the former.
"Do you need something, old man?" Adrian asked but what was really on his mind is, "Do not tell me that this old man will ask for a compensation."
