Martial Arts Master in a Spellcaster's World

Pfft, so what if they can cast spells? I'm a mixed martial arts master.
Every single time, these idiots thing they can beat me by simply tossing a rock spell or trying to blow me to pieces with fireballs. It's kind of hilarious to see their faces twist in fear when I get close enough.
They know nothing about fighting; relying on spells has made them weak... their bodies are all as thin as twigs.
Well, I guess I can't talk... for now, mine is quite skinny too. This new body sucks - but that's something I'll fix... wait, I have a system? Well whatever, maybe it will be useful.

Just like in the last world, I will rise to the top once more. These nerds with their shitty magic systems don't stand a chance.
They will all come to know and fear my name: Roylan.
