DxD: Building A Demon Clan From Scratch. - Chapter 133: Kill Me! (BONUS)

MAIN CHARACTER GET TRANSFERED TO ANOTHER WORLD WHERE HE USE TO INCREASE CULTIVATION OF HIS WORLD

I became a scientist for an evil organization.…But I’m too competent.

In a world where martial artists reign supreme, strength is everything. Unfortunately, that logic doesn't apply to a certain Florida Man.

Refined in the nuclear fallout wasteland, Leo was the strongest mutant alive. He carried an alien artifact, allowing him to exchange his lifespan for modern items. After 50,000 years of solitary life in a humanless world, he collected enough lifespan to transmigrate to another habitable world.

Leo was later thrown into a mysterious planet. He soon discovered that his body produced radiation, and it mutated the surrounding plants and grasses. Worrying that he might ruin the beautiful planet, he chose to live in seclusion.

Unfortunately, the local population soon discovered his existence, and a misunderstanding ensued.

He was the cold-blooded prince of the Jin country. Decisive and smart, he had looked down on the world with apathy and disdain.
