21st Century Archmage

“Greater Air Boom!”

I cast a 7th Circle offensive spell that I created for aerial combat.

Despite being a 7th Circle spell, the incantation wasnt very difficult. I densely compacted the mana density of the 4th Circle spell Air Boom to maximize its destructive power.

This was the moment marking this new 7th Circle spells worldwide debut. Having absorbed its fill of mana, the magic shot off, leaving a trail of blue light.

“Air Shield!”

We were about 2 km away from the enemies. Since I hadnt had a chance to determine the exact performance of Greater Air Boom, I cast an Air Shield around Bebeto that could simultaneously offer physical defense and block air waves.

‘Its exploding!!!

As expected of 7th Circle magic, Greater Air Boom absorbed a great deal of atmospheric mana as it flew at a speed slightly slower than a spear. Then, it reached the place directed by my will.

Flash!

At first, there was no sound. Like a pouch of light bursting apart, blue kernels of mana scattered into innumerable fragments and spread.

Boom!

There was only a small boom to begin with.

‘Hrm?

It was so quiet that I started to wonder if something had gone wrong with the mana or the incantation. I watched the spell radius with eyes of alarm.

BOOOOOOOOOOOOOOOOOM! BOOOOOOOOOOOOM! Ruuuuuuuumble! BOOOOOM!

‘Gahh!

However, I need not have worried. Explosive booms with the auditory impact of hundreds of lightning bolts striking in one concentrated spot rocked the air.

“A-Air Shield! Silence!”

The massive explosions even rattled my eardrums. I hastily cast Air Shield and Silence simultaneously around me.

“…..”

Boooooooooooooom! Boooooooooooooom!

With Silence and a doubled Air Shield, the explosions were muted to the level of popcorn kernels popping. The sound was reduced, but my eyes were growing bigger and bigger.

‘Holy… holy shit.

It was utter chaos.

The kingdom wyverns and their Skyknights had been posed to attack, ready to throw spears at me and the imperial troops as we came into firing range. The moment the spell exploded in close quarters, the ten or so wyverns at the center of the explosion were strewn into thousands of fragments, turning into a bloody rain.

That wasnt all. The explosive power of the spell was so insane that most of the wyverns in the sky were sent crashing to the ground, their eyes rolled back. Air Boom didnt have much physical force, but because it was fueled by a mana quantity near the 8th Circle, the kingdom wyverns dropped from the sky like dust motes being scattered by a broom.

I could hardly believe my eyes. I might be a 7th Circle mage close to an 8th Circle mages level, but I had never imagined that my spell would bring about such devastation.
