Arifureta Shokugyou de Sekai Saikyou (WN) - Chapter 404 - Three Don’t Say I’m Disqualified as Human

Long ago, there were people who stood upon the earth with their heads held high. They never bowed to anyone because of their indomitable spirit. They were capable of controlling wind and lightning, and conquering dragons and serpents. They seemed strong enough to split the earth and shatter the stars with their fists. They traveled throughout the land and called themselves Magi. Eventually, one of them would become a Supreme Magus! These men are the ancestors of human beings. Their blood is what we all share today.

This world, this game of destiny...

- Description from novelbuddy

Living things really are ignorant – the greed to obtain the key to knowledge and the fundamentals of energy overpowers them. Little do they know that knowledge is full of lies and energy is the root of destruction. Us, mages, have mastered travelling through space and time. We are invincible, we can turn worlds into dust and you, mere ants, will be wiped out with no trace.
