I created my own system

The frozen ground was no more, the battle melted the snow. The lightning had burn everything including the very bones of those unfortunate beast. However with the strengthening snowfall everything is turning white again, within seconds it become a blizzard of death, thick, icy sheets of snow crashing across the battlefield like waves of pressure. After the initial onslaught, the first wave of magical beasts lay either dead or burning though now they are merely being buried in the snow. The ground trembles more while mana became heavy, the next wave was even more monstrous—dozens of high-ranked magical beasts, coordinated and relentless. They are swarming in great waves to the extent that the cannons and ballitas are being overwhelmed, which surprises even Alicia.

"I should probably make a move" Alicia as about to cast a spell when she heard Sonya.

{We will take care of this horde reserve your strength for the coming days}

"Okay but don't worry I am not the type of person to get tired"

{That is why we will need that once a greater horde arrive, for now refrain from any kind of interference.

"Noted miss senior mage"

A second later after that conversation Apollo landed back at the watchtower platform, panting slightly.

[Your vitals are unstable, Creator] Jeremiah warned. [You are over stimulated]

"Cant be help I never saw such amount of enemies before, they are even more higher in number than the time I enter the demon subjugation army, these numbers I never seen something like this"

[That is why you need to use other spell, that doesn't consume too much power, remember Creator the blood season will last for five days]

"Jeremiah you know I have more reserve of energy than anyone here"

[I know but you shouldn't recklessly jump into a fight. I know you are powerful but dont be complacent]

"Alright point taken, thank you"

{Deploy the mechanical soldiers. Phase 1 formation}

{Command confirmed... coordinates and enhancements are ready.....]

The walls that protects the mines and the trenches around the fortress, sudden made a chorus of hissing steam and from those noise a gate open. One by one, mechanical soldiers, crafted from mythril-alloy and mana-hardened bone, rose eyes igniting with mana enhancement that was bestow upon it. On their metal like arms carried oversized halberds, elemental rifles, and tower shields enchanted with mana disturbing spell, similar to how Apollo's bullets works.

A low-pitched hum filled the area as the soldiers marched out in synchronized steps, the snow unable to slow them down. The sound of their metal feet crushed the frost, and the hiss of steam-cutters lit the night like flares.

"It seems they are already more powerful than the first time I saw them, I wonder how powerful they will became once sir Gavin perfectd the magic that I gave him. Well I suppose I still need to wait"

The battle continuous and all sorts of combinations of explosion echoes shaking even the fortified fortress.

"How come they are still coming!" Apollo was agitated the number of magical that is swarming up are more than what they received last winter's blood season.

"This is far too enermous, even the traps are useless against their numbers"

[Just focus Creator we should study them, we might not know if another unexpected happens}]

Apollo just nodded but then something attracted his attention.

The mechanical soldiers were already locked into combat, the mages of the tower were already to gather in the watchtower, ready in formation to attack. Each watchtower has a group of mage that stood in a spell circle glowing with runes that will empower spells and make thier casting faster.

"Lets begin, just like what we usually do lets do this!" shouted Sonya, her staff glowing as she started to chant along the other mages.

The current conquering spell became even more powerful assisting the new spell that is about to be cast. Inside the protective barrier hidden among the watchtower stood Vesta who as still playing her flute, Blair who is assisting Vesta's casting, then Agnes who already using her blessings to slow down the pouring enemies. Kieth who is increasing the gravity every minute and Samael who continue to use the power of the sacred flames to ignite the bodies of the weaker beast. Then here's Aaron who kept helping Arabela and Jillian in reloading the cannons and ballitas since thier three friend, McKenzie, Casper and Matilda continue firing without taking a break.

{Mckenzie aim at the ground, there is an enemy hiding there}

{Alya my radar doesn't pick up anytime are you sure?}

{Just fire your canon and why do keep doubting me, since when did my gut feeling wrong? Just fire!}

With her intense scolding Mckenzie and Matilda deciding to pay heed to her and shoot the ground. The ground shook and along it is five bodies they didn't expect to see.

{See, now more are coming tell Niko and Braiden to get the laser ready}

{Hear that you too, be ready!}

{Sure!}

{I am ready!}

Sonya and the other mages couldn't help but shook their heads at the banter but with the class help thier burden was decreasing. The position that should have been filled by the Blue moon tower and Black tower were replaced by the class. And to the reief of the Red sun mages, the kids are doing great.

From above, a cascade of high-tier spells rained down. Aurora Spears. Glacial Collapse. Mana Disintegration Arrows. Spatial Crush Orbs. Sacred Firestorm. The entire forest line glowed with auras of every element known to man.

The sky looked like it was bleeding light.

For a moment, silence.

Then came the beasts' response.

From all sides of the forest, the creatures howled and screamed in unison, and their mana surged outward. Dark shields, crafted from snow, roots, and ice-formed bone, materialized mid-air. At the center of their ranks, a Celestial beast roared, and the sky shattered into ripples of mana.

The spells crashed into the shields and were stopped. Explosions tore the earth but did no real damage to the enemy. The coordinated defense of the beasts—a rare, counterattack lead by thier instincts alone. Those attacks sent a shockwave that momentarily shook the entire mine.

"...They blocked it?" gasped one of the tower mages.

"No—they countered it."

"Attention we had one...no!..two troublesome enemies that is dashing fast towards the first layer of walls!'"

{I'm on it}

{I'm already shooting it!}

{Hey Braiden I think you should be moving that fingers now}

{I'm actually done killing it already!}

Apollo was a bit exasperated hearing their argue but somehow hearing them like that unexpectedly made his nerves a little calm.

"I should help out"

The mithril spear moved with wave of his command and without moving from where he was, his spear dance across the snowy field dying in red.

Another barrage from the tower mages followed. But again, the beasts—now with clearly combined spell defense abilities—met them halfway.

Despite all there effort the fight became a stalemate. The battlefield turned into a freezing chessboard—neither side gaining ground.

Until—

A thunderous explosion signaled the group of beast to retreat, their speed however was slowed that they could not even dodge the heat.

Then, with the force of lightning, Apollo returned, cloaked in mass cluster of electricity. Each beat of it brought thousands of volts that is ready to pulverized its targets.

"Thunder aura Negative lightning"

A bolt of lightning branch out spreading towards the end of the horde of beasts. But he wasn't done yet his spear was thrown, accompany by a command that bend Bunag to obey him.

"Gravity hundred times"

A wide radius of land were flatten by the sudden weight. With the might of his command together with the layers of already cast spell, the magical beast had no room to dodge. They can just brace the might of the spell without any options.

"Thunder aura, Ten thousand Lightning tribulations"

The air became heavy, charge with tension and pressure.....

And then...

Light tear down the sky, it exploded and a hot mass roll down. It was heavy boiling everything with the impact that could rupture anyone's eardrums

Each bolt branch out and carve deep craters into the ground, it melted the snow, it melted the ground. It burn anything yet somehow several figures still stood still.

"They have useful skills"

[Some of them have good affinities with fire and lightning so your spell was nothing to put them in danger]

"Right, then analyze them and give me their weakness"

[Affirmative, commencing battle gears]

Apollo's glow and in his vision shows dots that show the places he needs to strike while the color of it indicates the elements.

"Thank you"

The boy's figure disappeared and a trail of light was the only thing that be seen as he left.

He immediately cast several spell with the help of his spear,adding the chanting bracelets on his wrist. Five spells were immediately cast aiming at five different beast.

[Creator dodge!]

Apollo pay head and after he casted the spell he move to dodge the incoming fire spell from his back.

"Enertia" he commanded and the beast that attacked Apollo could not move.

"Thunder aura, positive lightning"

A second later a lightning struck, killing it.

"Okay show me more Jeremiah"

[On it Creator]
