Endless Twins

Three thousand years ago, a commoner boy walked out of a small village. After many hardships, he grew into the most powerful king in the world. Finally, he single-handedly fought against all races and twelve god-kings, expelling all races from the world. The remaining races also went into seclusion. After ending an era of turmoil and allowing the human race to stand on the top of the continent, he retired after his success and shattered the void to pursue his origins. Three thousand years later, the continent was in turmoil, chaos gradually emerged, thousands of races were born, strange demons first appeared, and the God-King returned. Can a black-haired boy from another world turn the tide and save the world? Unravel the mysteries of the continent? Discover the nature of the world? Finding your identity? Where should the human race go? Is it destruction? Or, a new student? The black-haired devil: "I don't fight for the world, I only fight for what I love."
