I created my own system

Sato, no, Alphonse's face became swollen due to the impact of Sun's strike. Though the latter immediately recovered and covered himself with aura.

Sun just observed and even when the miasma covered the entire area his vision could still see through everything.

"He is proficient in mana control and Ki circulation, we have a fighter mage here"

So Sun began to form his stance while a pair of bracelets adorned his left and right wrist. His eyes then scan his opponent's stature fully engraving its every movement in his mind.

"He is moving now!"

Ki circulated inside his body like a rolling engine while mana sparked upon his command. A mixture of two energies created a powerful synergy that almost left Alphonse surprised.

"I should have known you were hiding your trump card" he voiced out while an artifact envelope his body.

"Trump card?" Sun scoffed at his opponent's words before continuing to speak, "Unfortunately Sir Alphonse you are unworthy to witness it"

After speaking such words the two fighter mages took a step forward and began their magic slugfest.

The entire dungeon is now filled with magic miasma that already causes a zero visibility area. However, amidst the deathly field of smoke strong vibrations and clashes of energy shook the very ground of the underground labyrinth.

Sun who continues neutralizing all attacks from Alphonse began to see the patterns and traits he has.

"He seems to be a mage who specializes in lightning magic and is skilled in acrobatics and hand-to-hand combat" he could conclude since each of his strikes has the power of lightning while his flexible movements and strong punches only cement his conclusion. However Sun doesn't dismiss the fact that this must be a feign move to deceive him.

So to test his reaction again he pointed his hand towards his opponent and chanted "Wind Element, Air Gun"

A compressed bullet of air punctured through the deadly fog until it made its way to Alphonse's face.

The receiver of the attack was taken aback since his vision was being hindered by the miasma. So to evade the fast-moving projective he had no choice but to charge himself with lightning.

"Hmmm....he is not casting, is he perhaps using instant incantation?"

That immediate magic response was way too quick especially since lightning spells are very long to cast. Normal mages would switch to wind elements to have a fast incantation process.

"Interesting"

Sun now turn the tables he is now on offence while Alphonse is on defense.

"Let's test him more," he thought as started by darting towards his opponent with incredible speed, using a combination of clinching and wind movement enhancement.

Feeling the approaching presence, Alphonse prepares to welcome his opponent. His body crackles with electrical energy as he prepares to unleash a spell. Then as he got a clear vision of his target he immediately released his spell. A pulse of an intense cluster of lightning took a sharp turn and went flying towards the speeding opponent.

Due to the spells being cast the surrounding miasma was suddenly blown away. That resulted in their field of vision being suddenly clear of any hindrance.

Sun saw the incoming spell and immediately tilted his body to the side to evade the attack without losing his speed. Then he firmly planted his foot on the ground before doing another clinching. This move closed the distance between the two which took Alphonse to raise his guard.

Wind channelled across Sun's body and with his swift movement, his opponent had no choice by to put his guard on.

Alphonse stands his ground, focusing on the ground beneath him. He channels earth magic to create a defensive barrier, a low, vibrating shield of rock and soil that materializes in front of him.

Sun frown not expecting a different element than the one he previously used. However, it doesn't really matter as his fist drills through the defensive shield.

A cracking sound was heard and the shield was broken to bits.

As the fallen dirt momentarily blocks Sun's vision Alphonse took this opportunity to perform a quick, spinning kick imbued with lightning, aimed at Sun's chest. The kick generates a burst of electric energy intended to stun him.

He moved very fast however just like before Sun had anticipated the attack and used his barrier to absorb most of the electric charge. He then counters with a low, sweeping kick that sends a shockwave through the ground towards Alphonse, trying to destabilize his footing.

Lightning created a speedy transit of message across Alphonse's body which is why he immediately avoids the shockwave by leaping into the air, his form surrounded by a crackling aura of lightning. He then summons a lightning bolt and hurls it directly at Sun from above.

In response to this attack, Sun reacts by raising his hands, causing the wind to redirect the power of the lightning. As he sees his opponent being busy Alphonse lands gracefully and uses his agility to close the gap again. Then he performs a series of rapid, electrified punches and kicks, aimed at Sun's midsection and limbs.

However just like before Sun had anticipated his attack and adopted a defensive stance. It felt like Sun was reading his opponent's mind since his precise and measured movements deflected Alphonse's attacks. His movements are heavy and deliberate, but each block is powerful enough to redirect his strikes.

Then the moment Sun redirected his opponent's attack to the side he decided to go on the offensive. He stomps the ground, causing a series of jagged movements of wind to erupt in Alphonse's path, forcing him to jump and maneuver through the dangerous terrain.

As he deftly evades the strike, he retaliates by conjuring a chain lightning spell, which forks out towards Sun in multiple directions.

"Just what the hell is up with him!"

He said while his breathing was getting worse, he thought when it came to speed he should be able to win but the way his opponent uses the element of wind left him no room to catch his breath. So at that moment, he wanted to end the fight. Before the deathly fog returns, he must finish his opponent.

So within his hand, a powerful lightning spell sparks up. Sun responds to that attack and using his wind magic he creates a solidified air that disrupts the chain lightning's path. This causes it to dissipate before it can fully reach him. He then charges forward activating a spell he has been casting from the start of the fight.

"Wind Element, Tempester, Focus, Hundredfold"

Knowing the power of that spell Alphonse felt his blood begin to run backwards.

"Damn it!" he shouted with a bit of panic as he uses his agility to avoid the spell. Even with the spell's pressure he forcefully slides between Sun's legs and delivers a quick, electrified elbow strike to his lower back.

Sun grunts in due to being surprised but quickly recovers. He slams his feet onto the ground, causing a massive wave of wind that sends ripples and cracks through the dungeon floor. This causes his opponent to lose his balance.

"Argh!" groan of Alphonse feeling that the energy in his body went haywire due to Sun's casual stomp.

However, it is not the only thing he needs to take care of because the miasma is getting closer, it begins moving back towards them. So the first thing he did was leap high into the air, avoiding the wind ripples on the ground. Then he prepares to unleash a final, concentrated lightning strike from above.

Mana seems to be manipulated at a single point and the poisonous air is blown away.

"Lightning Element, Lightning Strike"

Sun didn't just stand and on his hand was also a spell he had cast.

"Wind Element, Zephyr"

Lightning and wind suddenly meet causing a clash of mass of electricity and air.

Many things blew up including the miasma while the ground was going everywhere.

"NO!"

Alphonse shouted feeling his arms weak due to the weight of the clash. However opposite to his situation Sun was unscathed and no emotion can be seen on his face.

"Damn it, what kind of monster are you!"n/ô/vel/b//jn dot c//om

Blood drips down from his eyes, mouth and ears however he can't stop.

"I should probably end this"

While Alphonse desperately clung to his life a voice devoid of any emotion suddenly went towards his ears.

Then from Sun's body, a pulse of electricity danced across his body as he raised his other free hand.

"Ah, I forgot to say..." he began to speak while a smirk slowly formed on his face.

"I can multicast"

That smug expression drove Alphonse to madness causing him to put even his life force to push through the clash.

"Combination spell, Windstorm"

Sparks of massive amounts of lightning flow through the gaps of wind and channel its power on it. As they became one the cluster of wind turned into a cluster of clouds. These clouds generate a bolt of even more powerful lightning.

"Goodbye Sir Alphonse" Sun just said while witnessing how his opponent's body disappears.
