Leon had to use Transfer many times before he could get close enough to the castle to the point where he could touch its walls. The building was massive. It was ten kilometers tall and forty kilometers long and wide. The material was just regular earth, and it looked like it had been made by the same woman who talked with Leon.
"I wonder how many years it would take to build something like this with my current status," Leon rubbed his chin. "Rather, why build something so massive? Just to show off or level up her skills? I guess it is probably the second option... I did something similar, creating the spear that killed the galactic snake, and I received a lot of points."
There were no windows on that building, but it had four massive entrances that were being used only by the elementals. As expected, they were leaving in groups of fifteen and walking toward very specific locations... they were going toward several purple crystals.
