Earth Instance Dungeon at My Side

Everyone thinks I'm a genius, able to learn anything and master anything I practice. They have no idea that I have a gateway to another world, where I can get dozens of times more time than everyone else.

With dozens of times more time at my disposal, what could I possibly fail to learn?

I have the support of the entire civilization of Earth to help me forge ahead!

So, you losers, are you ready to be crushed by me?
