Ymir's Holy War - Chapter 16: A deal. A bet. A contract.

Laws govern existence. Arcons enforce those Laws. Across the countless worlds, civilizations live and die beneath their silent authority.And within such worlds Mana Regains supreme.But, Kairos was born with none.A manaless orphan with nothing to his name, he carved his way to the top through Aura alone, becoming the strongest user in recorded history.For generations, the people lived beneath the dome they believed was their prison, a cage holding them back from the world beyond. They tore it down.They celebrated. But when the dust settled, they realized how wrong they were.Without it, the continent's pillars crumbled, and Kairos fell with them..Fate, however, doesn't deal in injustice. It sent him back rewinding time to where it all began, granting him a second chance no one was meant to have.But the world he returns to isn't the one he remembers. A kingdom that never existed now stands. The worlds themselves hide secrets no commoner was ever meant to see. Strange phenomena ripple across the land with no explanation.Armed with the knowledge of a future already lived, Kairos sets out to reshape the very laws that govern magic, unaware that the entire history of the world has always been bound to his fate.-----“Ah one fire ball not enough, It's alright I will make em ten!”“I see, One enchantment isn't enough, how about ten of them?”“One arrow isn't enough how about one hundred of them”Tags#OVER POWERED FROM THE START#WEAKLING#HAREM?
