In the next few days, the curtain of light gradually shrank. As the curtain moved, Roland basically figured out where the center of the map was.
He estimated that the center would be the battlefield for the final battle.
So, F6 marched to that location.
On their way, they ambushed many other groups, explored a lot of ruins, and gradually replaced their equipment. With Roland's expertise in Enchantment, the quality of their equipment was increasing.
On the sixth day, Roland and his friends came to the center of the map.
This place had massive ruins. Taking advantage of their excellent equipment and resources that were enough to last them to the end of the event, they spent a day and a night clearing the undead creatures in this place and looting all the treasures in the ruins.
They found equipment of higher quality and countless magic materials.
