Of course, Hill didn't go into seclusion.
But he did need a little time.
After all, the adjustment and changes of spells from levels 0 to 3 were almost no difficulty for him, even those of the destructive type.
Even for spells like casting a big fire, Hill actually just has to use incantations, and he can't cast it instantaneously; it also requires a bit more mana input, though it's not that he can't use them.
You could say there's not much difference from ordinary mages; it's just not as effortless as his talented spells.
For spells above the Fourth Ring, Hill had no problem using them himself, but changing them according to this world's laws, especially those involving destructive laws, was a bit more troublesome.
Mainly because, after reaching the intermediate level, the magical energy of this world inherently carries some darkness... It's not just because most of the world's laws are controlled by the Lord of Hell, but also because of the despair within the world itself.
