The God-Slaying Demon King: Reincarnated as a Mere Mortal to Become the Strongest in History!

Once known as the Supreme Demon King who defied even gods, Hyram met his end battling the tyrannical Demon God. Refusing to offer sacrifices like others, he challenged the divine order itself. Though he fell in combat, his legend whispered a truth—no demon could ever overthrow their creator. Centuries passed before fate granted him a second chance, reborn in the frail body of a human boy. Considered the weakest species, humans held hidden potential beyond any demon’s grasp. Now armed with mortal flesh yet immortal will, Hyram embarks on a quest to shatter destiny’s chains. His twin goals burn bright—to slay the lurking Demon God that rules their world, and to reunite with Fillfee, the cherished daughter torn from him long ago. The battlefield awaits where human determination will clash against divine tyranny, as history’s mightiest demon walks the mortal path to ultimate vengeance. Through human limitations, he seeks to achieve what no demon ever could—true godslaying. Every step forward echoes with the weight of centuries-old wrath and the fragile hope of a broken family’s reunion. The world shall witness whether mortal flesh can bear the soul of the demon who dared defy heaven itself.
