Chapter 703 - Increasing stats

" All the Saints are able to break through to S-grade or you can say early Elite grade before anyone and they are also able to save our planet from those monsters who suddenly appear on our planet. All the saints were the one who established the warrior association and all those other associations that would be necessary to maintain the peace of our planet.

Like this they also created those Warriors schools and Academy where they also appoint other Warriors to teach students about the danger of those Monsters and characteristics of those Monsters.

The same thing I also notice present in Terraria. But here many people could graduate from the warrior Academy on our planet. You won't be able to graduate early even if you learn everything from your house or something like that.
