I like them big, do you? - Chapter 109: Bet with Aria

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.

You thought being reincarnated as an extra-side character was bad? Imagine being thrown into the body of a villain who is disowned by his own family and discarded by the author.

When she woke up, she had transmigrated into An Jiuyue, a woman living with two young children on a mountain after her husband abandoned her. She was pushed to the ground, and now, there was a bloody wound on her head.

With only a handful of rice left in the rice bag, she had relied on digging wild vegetables to satisfy their hunger every day. Her children were so often starved that they were all skin and bones. On top of that, a wicked woman threatened her to sell her son! If she refused, the woman would snatch him away forcefully.

But An Jiuyue took a deep breath, revealed her sharp claws, beat the woman up, and threw her out of the house. She could show the woman she was not to be messed with!

They were out of rice and vegetables now, but she was not afraid. Acquiring food using her spatial abilities was as easy as curling her fingers!

Moreover, her spatial abilities were unlimited, and her medical skills did not deteriorate. She could no doubt earn money and raise her children well!

As for her ex-husband…

The prince, who had returned from the battlefield, smiled maliciously. “My beloved concubine, please calm down. I brought back a mountain of gold from the battlefield as a gift for you and our children.”

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?
