I created my own system

A sound of thunder erupted, followed by a shockwave that blew the surroundings; the ground was torn up, creating a cloud of smoke that obscured visibility.

"I guess you aren't just relying on your weapon to fight," Apollo commented, seeing how Nero was able to block his last attack without being pushed back.

From above, a giant crater can be seen, and at the center of it are two individuals dueling at the torn ground beneath them, which began to be covered in flames.n/ô/vel/b//in dot c//om

Apollo has been executing the swordsmanship he learns from Mahika, not letting his opponent form his attack. He plans to completely overwhelm him before disarming Nero away from his weapon. However, despite his initial advantage at the start, the sword's might is still too hard to challenge, especially with Nero slowly adapting to Apollo's fighting style.

A radiant golden light arc with Nero advancing; midway to his attack, he began casting spells; these spells were rampant at the very start of the fight, but Jeremiah kept canceling them. Now, though, something was aiding the former king that made the artificial intelligence confused. What he cast was a different type of spell that didn't have a direct effect on his creator. That is why he couldn't cancel them like before.

Nero successfully cast his spell, creating illusory doubles to obscure his true position. As the images surrounded Apollo, Nero unleashed a flurry of sword strikes, each one faster and more precise than the last.

The receiver of the attack just smirked, his eyes narrowing as the skill Light of Aegis puts its maximum power to protect him, a dome of white light deflected the illusions and revealed the real position of Nero. Then, as if reading his opponent's mind, Apollo sidestepped a downward slash and retaliated with a spell-infused thrust of his blade.

"Fusion technique, Spell art!" magic and swordsmanship combine in a single strike.

The tip of Apollo's sword erupted with brilliant light, forcing Nero to fall back and shield his body. The power of the five elements was guided by the power of the sword, and the compressed attack brought great impact with it. And even distance wasn't able to reduce the power it has.

The tide of the battle keeps changing, and now Nero is being pushed back by a sword that barely existed than the one in his hand. However, despite the situation, he didn't falter. He immediately began casting another spell, one that could amplify his physical abilities and infused his strikes with bursts of explosive energy. Excalibur glowed brighter as he launched a series of calculated attacks, each blow perfectly timed to exploit potential openings.

Apollo reacted well and combined his foresight with his movements, so even with the fast rain of attack, Apollo was still able to parry and dodge, even landing a strike from unexpected angles.

The biggest obstacle he has right now is Excalibur's overpowering light. No matter what he does, it would block anything. It was the greatest defense he had encountered. He could not penetrate it.

"I should also do the same, overwhelm my enemy with more power," the boy said to himself as he gathered more energy from the stars. All the Apollos watching the current battle are not joining for this particular reason.

Back to the main fight, Apollo began to prepare for the final attack; he cast a spell while repelling attacks until it stopped due to meteors falling from the sky. Nero was forced to disengage, dodging the fiery projectiles while countering with sword armament, a sharp blade made from aura sliced through the smaller meteors. But while he focused on the meteors, Apollo started the plan; a command was enforced while the enemy's artifact was shut down. Gravity suddenly increases its pull, distracting Nero while he dodges; a window of opportunity comes with both Nero and the sword destabilize; Apollo doesn't waste time and follows that with a modified version of his bullet.

A gunshot rang, and the mana turned into chaos, disrupting Nero's body and Excalibur's connection to its wielder. The first steps were fulfilled, and before the enemy could even recover, one of the observing Apollo took his weapon, a bow and arrow. From the sound of bullets, it was then replaced by the hustle of wind due to an arrow being released. Five arrows landed on the ground, circling Nero; then the runes embedded on the body of the arrow glow, creating a field of shackles that bind Nero down.

In that moment of danger, Excalibur responded to its master's need, and the shackles were broken. The former king plunged his sword into the ground, releasing a holy wave, a burst of radiant energy that disconnected the gravity command and almost knocked Apollo back.

But it was still good, that outburst was well taken into consideration when Apollo created the plan.

Underneath the broken soil lie scrolls that were drilled under before gravity first struck. So when Nero released that wave of energy, the scrolls absorbed most of the power and activated. A focused attack consisting of 800 magic scrolls struck Nero, causing the weapon in his hand to fly away; it was only a split second because as soon as the weapon parted from his hand, it immediately flew back. But Apollo won't let that happen; the sword was suddenly clad by the system's power, disconnecting any connections it had with its wielder. Nero panicked when he felt that Excalibur was no longer under his command. Apollo's inventory opened, and the legendary sword was eventually sealed inside.

"No!" Nero shouted in distress as the golden light disappeared along with the sword.

Even with the sword gone, the fight is not yet over before Apollo can store the sword inside his inventory. Excalibur gave a portion of its power to Nero. The boy knew this would happen considering the info he got from the Sage's circle. So, as soon as his enemy was about to make his move, the energy he had been keeping from the stars began to shine. The scarlet red weapon in Apollo's hand suddenly turned purple until some parts of it had a shade of blue. The power of the heavens was swelling inside the sword, and with all Apollo's might, he swung it and struck the attacking enemy. An immense cluster of golden light clashes with the power from Apollo's sword, causing a deep crater to be created.

A painful cry was soon heard followed by a loud crash as if something hit the ground. A continuous draw of breaths soon reaches Apollo's ears as the remaining power of Excalibur disappears from Nero. The former king was down and unconscious while the wolf with him was running desperately to his side.

"I must say I admire how she didn't even leave him despite the current situation"

[I agree, so Creator we will kill him now? You are not bound by the oath anymore]

"Well, truthfully, I was about; however, it seems we caused so much ruckus that we attracted someone's attention," he said as his voice faded away along his body, "I will keep an eye on you, Nero," he added as he teleported away before the imperial soldiers see him.

As soon as Apollo was gone, a group of men arrived. These people wore the insignia of the imperial house.

"Well, it seems my dear brother got himself beaten," Augustus said; he was the one who led the army to investigate the riot that was currently happening.

"Brother..." Nero began to speak, "You wouldn't believe what just happened"

The emperor just shook his head as his eyes fell on a certain object, "Well it seems you are right, I might not believe how this happened"

Planted on the ground where Apollo was previously standing was a sword that made the battlefield broken as it is.

"Your imperial majesty!" The nameless soldier who was always by the emperor's side shouted in disbelief as the sword from the legend came to life.

"Excalibur" Augustus just said as he summoned the sword to his hand. The weapon glowed, feeling the command, and without struggling, it flew and obeyed the order of the emperor.

Nero defeatingly closed his eyes, knowing his brother had finally formed his connection to the weapon just like he did.

"Ha.... Really, I wonder where my plan started to fail." he thought so until a certain someone came to his mind, "I wonder why you didn't even see me, teacher." his mind trails off, thinking of a certain place that had long been forgotten by time.

"That demon.....I am certain he has some connection with that place. His attacks were too familiar to me almost as if he was a mage there like me...." Bit by bit, the consciousness of Nero is fading away; even Nepheline's cry wasn't able to keep him from falling asleep. Deep within his dreams, a certain person was waving at him, a man he thought he had forgotten.

"Teacher... Apollo"

Sounds of explosion came to his ears along with eyes that bore pain and hate.
