So, he has God-level magic access?
Oh boy, the wish-fulfillment in this story is really starting to get out of hand.
At this point, any conflict is gonna be pretty much entirely manufactured. He's got level 10 magics in a world where even the most powerful magicians top out at level 7.
Even this world's closest thing to deities are beneath him in power.
I sure hope that the author doesn't keep trying to pretend like this Ministry of Magic is any sort of threat to him, because like... Objectively speaking, they aren't.
