Born Without Magic And Disowned, The Returning Of The Weakest Who Trained for 666 Days
It was the 3rd age of civilization, the Age of Magic.
Equality is slim and equity is vague.
Energies and essences were the norm, how many you possessed or how good was it in your hands defined your status and power. Wheels was not a big thing anymore, for people were more focused on developing spells, curses and charms.
Borned in a noble Human family, I was the weakest, no, I was the one with literal zero magic among my siblings, the energy in my body was so little it could not be fused with any essences in existence.
Disowned, exiled to live on top of a mountain never expected to return, I can make one request before they my existence was deleted from society.
"Send me training dummies of all races and known monsters."
I vowed to be the strongest man without magic, training for 666 days before returning and make everyone regret what they did.

Expect reallllllly slow progress. Like, nothing much will happen until 666. So you can just bookmark this, wait 3 years when it's all finished before reading, I guess?
