After dying in laboratory tests, Klaus transmigrated to a Sorcerer World, in a strange and peculiar character whose existence is an enigma. He knew this world, for it was the world of the novel one of his students wrote. He also knew the character because he created it. But it was a discarded character; it never appeared in the novel. How could he have transmigrated in it? Reality hit him soon after when he was sent to cross through the first test that every sorcerer must pass to awaken his abilities. There, he will have to fight against powerful monsters, which they call Curses, and against other Sorcerers, all to try to enter the select group of Sorcerers to discover the secrets that await in this world and understand his arrival to this and his existence. Just when he thought his journey might be boring, he received a peculiar and mighty power bordering divinity, capable of making him reach unimaginable heights. Although a bit dangerous...

The little handsome son-in-law passed through a world as waste material and the husband of a wealthy family. But because of his lacking aptitude, the wealthy family had driven him out. So he worked hard and found a more powerful family’s thighs to hold onto. Soon enough, he became the strongest son-in-law and husband in history.

In this world, it was impossible to practice martial arts. It was futile so he might as well take advantage of his wife’s thighs and maintain a comfortable and leisure lifestyle.

He’ll train his wife to become the strongest and best person in the world.

“Whoever dares to provoke me, let my wife kill you!”

Project BIOHUMAN was supposed to be a quiet project that tested to see if they could create superhuman beings. The Creator, Dr. Vang Chang created the Numbers, ten individuals who took the BIOHUMAN serum and came out different.

Countries caught wind of this and demanded the Creator to disperse the serum to strengthen the humans. The BIOHUMAN serum was shot into the sky and dispersed all over the world. Little did anyone know, it changed Earth and everything living on it. Plants, animals and humans were genetically changed forever.

25 years later, the Creator's son, Lee Seng Chang is a high school student without any Biohuman powers. The serum had given him almost no Dark Matter and only increased his overall human abilities to a super-Biohuman level. Even with that, the power standing only made him seen as the weakest amongst everyone.

Picked on because of his powerless status, Lee Seng was left by all of his friends and labeled powerless. He desperately tries to keep going with a smile on his face. Lee Seng one day gets an option from a man with a Fox mask.

“Awaken your power but at a huge price.”

Lee Seng takes the deal and watches as the world he knew quickly changes and isn't what it seems. Put under the pressures of his Father's status and his new profound power and changes, Lee Seng battles the demons within him and the unknown coming for him.
