They prepared some supplies before leaving for the central continent. Someone who did not want to be left behind was Sully, who turned into his small version, hiding inside Arthur's pocket, waiting for him to leave toward a new area!
Speaking of Sully, he was growing stronger and stronger, having his power almost equal to that of an Official Mage. It was not there yet, but Arthur was sure he would reach that point given enough time, or perhaps with the usage of the bloodline treasure Arthur got from the dimensional realm, although he was waiting to use it when on the central continent.
Arthur wanted to know how to get to the central continent, and George was the only one that knew how, but Arthur was reluctant to speak with him, afraid that George was not someone he could trust.
Still, he spoke with him anyway, as he had no other choice.
Just like he imagined, the way to reach the central continent was through a hidden portal, but it was not a simple task to get to that portal.
