Hidden Desires - Family Secrets - Chapter 7 - 00 It’s just a nightmare, kiddo...

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.

Shaymon, the man who has achieved the apex of dark magic, is framed as being a Demon King and is killed.

The last subject of the college entrance examination, comprehensive science, suddenly became the basic knowledge of Eudemons!
Sitting behind the desk, Chen Qiyue looked blank.

Looking at the contents of this test paper and the students around him who were busy writing, the corners of Chen Qiyue’s mouth twitched.
He must be dreaming.
Otherwise, the world is crazy!

Inside the Phantom Beast Breeding House,
“Sir, which one do you want to buy?” the waitress asked weakly.
Chen Qiyue pointed to one of the phantom beast eggs, “I want it!”
“Okay, I’ll take it off for you.”
“Wait! I choose this one!”
Chen Qiyue pointed to another egg.
“Okay, do you want to change it?”
“hold on!”
Receptionist: …
half an hour later,
Chen Qiyue happily embraced the black-and-white Laqiu in his arms, and left with the blue-spotted egg.
The female receptionist suddenly turned pale, her legs became weak, she fell to the ground, and began to cry.
This person is too bad, he deliberately pointed out all these phantom beast eggs.
Chen Qiyue spread his hands, who made my golden finger have to be like this…
Heck, I’m a decent person!
