- Description from novelbuddy

Zack “Kazz” Foreman once was a human from the earth when humans went through a dramatic change because of an event. This forced them to evolve into energy-based beings but was sucked into another dimension.

Forced to start living out lives on random worlds in a fractured dimension, Humanity is placed on the path of complete extinction.

This is controlled by a demon king at a place called The Center of Everything.

The Demons try to force Humanity's mark from every reality, so there are only demons, but the Demon King feeds from anger and pain. A constant tournament going at the center of everything to feed his hunger.

Kazz made it to that point once, but was tricked, refused entry to the tournament because he had offed a place one of the gods of the worlds.

Refusing to give up, Kazz goes back to the beginning to start again. To do this, Kazz must give up all of his memories to choke the flow of demons born fully grown from a pool of recycled souls.

This journey starts after he lives a solitary life trying to get stronger but not knowing why. The world Kazz is on is like our earth, but it was only a mimic of the earth we know.

Caught using steroids and about to give up and join the army, Kazz stumbles onto a cave in the ground. He is transported to a world filled with demons and monsters, and a human god named Hero is speaking in his head.

Hero, a person Kazz knew but was not friends with, followed him to help but was lost from him. Upon meeting Kazz, Hero offers him the Hero System to help him advance in this new world.

Kazz refuses after trying to get to the top and failing to use the easy route. This starts a series of frustrating events for both Heroes, but they learn to work as a team over time.

Kazz will meet misbegotten monster girls and demons that he agrees to take care of in this world, using the Ranching System. It only gives bonuses to the girls and skills to help raise them, but he will also learn to control the Elements with Shamanic abilities.

Renji was nothing special. No wealth, no fame, no grand ambitions—just a 23-year-old gamer wasting his days in a cluttered apartment, escaping reality through the immersive world of Eternal Realms. In the game, he was powerful, respected, a leader—the elven king, commanding armies and shaping the fate of kingdoms. But outside the screen, he was just another nobody.That all changed the moment his world shattered.What started as a routine gaming session took a terrifying turn when his screen flickered, reality twisted, and an unnatural force yanked him from his chair. When he opened his eyes, he wasn’t in his apartment anymore. He was in a world of towering forests and ancient magic. He was wearing regal robes, a golden crown resting atop his head. And before him stood four elven women, their expressions filled with reverence and concern.They called him King.Memories not his own flooded his mind—battles, alliances, the weight of a kingdom’s future resting on his shoulders. It wasn’t just a game anymore. This was real. And the fate of the elven race now depended on him.But Renji wasn’t a hero. He wasn’t a warrior. He was just a gamer who had no idea how to rule a kingdom, let alone survive in a world teetering on the brink of war.But Just as he was pondering on it a mechanical voice sounded in his mind.
