Author's Reincarnation in a Fantasy Setting

Back at the Zaforths magic academy, things were getting out of hand. All of the students had long been evacuated out of there, of course, and most of the teachers as well. 

But there were still a few staff members who were left behind to try and make the futile attempt to protect the academy infrastructure. 

And it truly was futile, since all of them were gruesomely murdered by the demon beasts within a few minutes. As of now, the academy grounds were open to the beasts, and they were ravaging all over the place. 

Destroying the buildings and places where they could find the smell of humans or any other living being. The academy grounds were dead, with no humans left there except the beasts. 

However, that soon changed. The air inside the basement chambers began to distort as the magic circle craved on the floor lit up, emitting a bright flash. 

When the light disappeared, it revealed the figure of a man named Ryfin—he had an exhausted expression on his face as if he was being forced to do something he really didn\'t want to.

"My my, just look at this place," he mumbled, casting his gaze around the basement that was now demolished. 

Although he could hear their sounds coming from above, there were no beasts in the basement.

"Ah well, let\'s get done with this too," he sighed. And with the same exhausted and bored expression on his face, he began to walk out of the basement. 

Fortunately for him, there were no beasts on the staircase either, thus he was able to come up to the grounds without any interruption. 

However, that happiness didn\'t last long since he caught the attention of all the beasts that were roaming on the academy grounds. 

All of them looked at him, growling and baring their fangs toward him. Some stomped the ground while some roared so hard as to make the ground rumble. 

"Woah, scary~" Ryfin whispered as he looked at all this. "Well, I want to finish this soon so I won\'t be fighting with you all. Sorry, but I hope you don\'t mind."

Saying that he activated a spell. Two intricate symbols materialized beneath his feet momentarily before dissipating. Within a few seconds, a gentle undulation rippled through the surrounding grass as he gracefully ascended, seemingly levitating above the ground.

In no time he was up in the air, even higher than the tallest building in the academy

"Well then," he said as he glared down at the academy, his hair billowing due to the air currents in the sky. 

"From depths concealed, in Ebony\'s embrace, Purify the impure, darkness\' grace: Shadow barrier."

Right after he completed the incantation, a blackish-purple wall emerged from the ground and took the shape of a dome-shaped barrier around the academy campus. 

"Good, now I can do this without worrying about accidentally killing any civilians who might be alive," Ryfin said, he was inside the barrier. 

He lifted his hand, unleashing electric sparks fueled by his mana. A magic circle formed, converting his mana into a growing sphere of pure energy. It swelled to the size of a triple-story building, then swiftly contracted, shrinking to the size of a tennis ball.I think you should take a look at

"Inferno…uhhhh, whatever explosive attack!" Ryfin said and threw that shining red ball of energy toward the academy. 

Upon impact, the energy ball expanded in a split second, covering all of the academy grounds and causing an enormous explosion. 

All of the buildings, infrastructure, and even the ground, vanished without a trace—all of it evaporated due to the sheer strength of the spell. 

The explosion was so colossal that if the barrier had not been there, the surrounding city would have also been demolished. But the barrier contained the explosion within itself, and that ended up increasing the damage inside the barrier. 

Now of course, when the smoke screen settled down there was no trace of the demon beasts as well. The entire ground within the barrier had been leveled clean, there was nothing left there. 

Except the man levitating up in the air. 

"Well, well, it was better than I expected. Although it would\'ve been even great if I got to name it first," he said to himself while looking at the destruction he caused. 

"Anyway, can\'t do anything about it now. I\'m not that good with naming after all—I\'ll probably ask Auciel to choose a name for it."

It was not unnatural for him to not have named this spell yet. After all, this was a new one he had created only recently. The spell he just unleashed was an imitation of an attack from the demon he had fought. 

He thought the attack looked cool, and decided to own it. 

As for the reason he just went and wiped out the Zaforths academy from the face of the planet, it was because those were the exact orders he got from the academy director. 

And it was totally understandable. Along with training students, the Zaforths Academy was also a hub for R&D on magic. 

There were a lot of important artifacts and magic items that were stored here, and while the most precious ones were transported to the safe zone, taking all of them was simply impossible. 

However, they couldn\'t let these fall into the hands of demons—since there was no knowing what they might do—thus the easy option was to blow everything up. 

That is why when everything and everyone was transported out of the academy, Ryfin was told to destroy everything on the campus so no one could use any information or magic item against humanity.

"Phew, finally done with everything after all," Ryfin exhaled as he looked at his surroundings. 

He released the barrier around the academy and was about to teleport himself out of there when his eyes wandered off in a direction he didn\'t want to look at—toward the city. 

Right before his eyes, many people were being killed by the demon beasts. The beasts were indifferent, whether it be a man, a woman, a child, or an infant. 

They knew just to kill, and killing was what they were doing.
