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.

My Beast Evolution System

Glimmer darted forward with the flames engulfing her body as she tried to weaken the body of the beast, and Thunder followed right behind her.

Diana charged in and her blade flashed in the light as she struck at the exposed bone of the beast.

The battle continued for a while, but in the end, Frostfang appeared out of nowhere to help them as well.

Together, with the wolf, Aaron and the girls were able to slay the beast and all the remaining demonic beasts in the barony as well.

"It's over." Aurora leaned heavily on her staff with a pale but relieved face.

"It's done," Diana sheathed her sword while breathing heavily.

Aaron placed a hand on Thunder's flank and his gaze swept across the chamber. "We did it. The graveyard is ours now."

"Yes, but the amount of miasma in the air is still concerning."

49. Final Threat.
