The Chef Rules the Last Days - Chapter 198 - 196:

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.

Xia Ming, a university student who just graduated, accidentally got hold of a system. Xia Ming became powerful! Medical skills? OK, I don’t have the skills. But on the following day, even the highly skilled doctors couldn’t be compared to him.

Force? OK, I’m not your match today but on the following day, even the Great Master would have to concede defeat.

Basketball? OK, I’m a fusion of the world, the strongest basketball star, would I be afraid of you?

Wife, that is even better. I have a beautiful President Lin, and a Missy who is like a rose. Each of them is beautiful, how are you going to compare to me? … … You guys spent a hard time learning skills, acting but I am different.

I have an Almighty System, what skills do I not have? As long as I’m willing, even the celestial beings cannot stop me. With Xia Ming’s words: “As long as the system is in my hands, the whole world is under my control.” I am Xia Ming, I speak for myself.

Or," his lips turned into a sly smile as he whispered close to her ear, "Be my boyfriend." He even dared to wink right before her as his dark orbs glinted amusingly.
