It was first considered that it is better to start your adventure when you are young to it easy to get magical powers. If you don’t do a younger age then they will hardly grow. A thirty-year-old Rick Gladiator proves this wrong. He started his adventure at the age of thirty and got magical powers even achieving the highest rank in them. No one can compete with him. He built his team and then they fought with all the monsters and that adventurer who underestimated him.
