The Simple Life of Killing Demons - Chapter 87Book 12:

Aaron, a wildlife biologist, became a military strategist right after a global war between nations began.He never wanted to participate in the war but he had to, because he wanted to continue his studies on endangered species the moment the war was over, but to his surprise, everyone in his unit were killed, including him, and the next thing he knew, Aaron woke up in the body of a young noble having a similar name to his.However, he also noticed he had awoken in a world different from Earth.In this world, demonic beasts ran rampart with only one thought in mind, causing them to feed on anyone they see, be it humans, elves or even magical beasts as well.During his first encounter with a magical beast, Aaron awakened a system which allowed him to bond with magical beasts and to obtain terrifying abilities from these bloodcurdling magical beasts, so he used his experience as a wildlife biologist to help make it easier for him to bond with these beasts.However, Aaron also noticed he could evolve these beasts if their loyalty towards him had reached a certain level, so he vowed in his heart to grow strong enough to protect those he cared about in this world with the hope of living a happy, peaceful life where he'll be able to focus fully on his passion as a wildlife biologist.

In a game-like world where dungeons, monsters, and players appear.

Humanity achieved dominion over the galaxy long ago.Once that was accomplished, they turned their ingenuity inwards. With their prowess over biological engineering, they transformed themselves into deific beings now called the Gene Tyrants. For centuries, the Gene Tyrants terrorized the galaxy, designing and abusing their genetically engineered servants and serfs as their whims took them.No tyranny can last forever, though, and the Gene Tyrants were eventually overthrown. The rebels discovered a strange light of the mind called Aether, which gave them the strange and fantastical powers they needed to eradicate their creators. Once that was done, however, that by no means meant peace.In the thousand years since, the face of the galaxy has changed. The most powerful human civilization is called the Supremacy, the homeland of 'might makes right'. In the Supremacy, a crime committed by the strong is no crime at all. With their military strength and mastery of Aether, the Supremacy has spread across the galaxy -- with the other powers able to do little but stall their advance. This struggle has developed into a cold war, and that cold war has frozen over for years now.Dragan Hadrien, a low-level administrator in the Supremacy, cares nothing for any of this. Dragan's primary concern is getting himself a promotion and taking it easy for the rest of his days. When a mysterious prisoner is brought aboard his ship, he thinks he has found the means to do just that.How naive of him.

“I thought I was becoming powerful, but it never occurred to me I was inching closer to the abyss.”

The Blue Planet: Earth.

Shane was living a beautiful life. He was a topper in his university. Girls flocked around him like birds and bees. His friends treated him as some God.

Everything was good until he was electrocuted.

If you are wondering if his adventures have ended, you're wrong. This was just the beginning.

The next moment he opened his eyes, he became something he never dreamt of—a system. Wait, why wasn't he a host instead?! Wouldn't people enter into amazing fantasy worlds with a cool system after dying?

Why did he have to wake up in a white room?!

He thought everything would be fine even after becoming a system. What could go wrong when he just had to sit behind the desk and handle different hosts?

Boy was he so wrong.

He could use Dark Cosmic Energy! Something only demonic beings could use!

What was going on? He was a human being in his previous life! How the heck could he use demonic power?

“D-Destroy….” Shane's mind buzzed as he thought of something, “Y-You don't mean…. I-I have to destroy an entire world?”

“No,” When Ed said that, Shane's shoulders relaxed as if he had been unburdened, only to freeze again after hearing the next words: “You have to destroy worlds.”
