Reincarnated Hero System

Explosions of varying magnitudes rang out, with clouds of dust, smoke, flames and other elements rising up into the sky.

Thousands of magic circles of varying colours covered the sky as the undead mages clashed with the mages of Kasteblum, along with screams of joy and pain alike that rang out occasionally.

The commanding Dullahans used battle strategies against the resistance force, in an attempt to breach the tall wall of earth magic that had been constructed to serve as one of the last lines of defence against Vazgan's army, however, they were no match against the veteran army lieutenants and captains under Sir Luke.

Chaotic and Disordered.

Those two words were best to describe the current scene of the battlefield.

On one end, the Dullahan commanders and the military officer-ranked personnel were engaged in a battle of strategies, while on the other end, it was basically an all-out brawl between the adventurers, mercenaries and the undead.

Some knight platoons could be seen working together to take out droves of undead while others had long been either scattered or completely annihilated.

Black and red blood splattered in the air as both living beings and undead fell, never to rise again.

On a side note, any liches that were spotted were instantly attacked by a combination of high-ranked paladins and mages, in an attempt to prevent them from resurrecting the fallen combatants as undead.

The air which would normally carry the sounds of rustling leaves, small streams and nature's wildlife was now merely a canvas for the stench of 'death', along with the screams and shouts of combatants on both sides of the battle, those living and those who had crossed into the realm of undeath.

Explosions rang out in the skies as the high-level mages combated the Elite Dullahan troops who were mounting nightmare horses with the ability to ride on air with a skill similar to Evan's void steps.

However, they were unable to face their opponents undisturbed as the Dullahans and other undead with long-range skills and magic kept interrupting them every now and then.

Just as one of such undead was about to perform its routine interruption, its head was pierced by a red flaming spear, with its whole body going up in flames the moment after.

**SWISH!!!

A jet-black blade sliced through the air, releasing multiple black slashes that cut through the body of the flaming undead, as well as every other undead creature within a twenty-metre radius.

The wielder of this blade, flicked off the black blood on the blade to the ground before turning around and walking in the opposite direction, while the bodies of the undead behind them slowly split into five pieces and dropped to the ground.

Seated on their shoulder, was a small humanoid of about 30cm in height, with red hair and eyes, twirling around multiple rings of fire on her fair fingers.

[I need wind and lightning; I want to use my new skill.]

The small humanoid girl, High-rank Fire spirit Amy, spoke to her contractor, the Demon of pride who bore the same name as the deadly sin she embodied.

"New skill? Okay."

Pride replied as she coated her sword with pitch black coloured energy, before releasing multiple arced slashes both in a straight line and about 60 degrees in the air.

These slashes went on to shred both the ghouls running towards her and the ones who jumped in the air, along with the two undead crows into pieces of rotten flesh that fell onto the ground.

She then crouched slightly, before pouring magic power into her legs and jumping hundreds of metres up into the air.

In the few moments she spent in the air, she scanned the area she was in and spotted a particular location that had thousands of opponent-less undead, probably reserve forces that were not ordered to participate in the battle yet.

The high demon then activated her partial avatar, generating a small arm with the energy of 'pride' and stretching it out to grab the tail of a nightmare horse that was the mount of one random Elite Dullahan.

The Dullahan instantly realised something was wrong and quickly abandoned its mount, saving it the pain of being flung to the ground in the next moment like the nightmare horse that Pride had grabbed by the tail.

Just as gravity began bringing her back to the ground, Pride used her own avatar as a foothold and kicked off it, shooting through the air and towards the undead 'reserve?' force.

The high demon completely ignored the poor platoon of knights that were now saddled with the fae of having to battle the nightmare horse that suddenly crashed in front of them, as well as the mountless Dullahan which was quickly bombarded by multiple tier 3 magic spells, courtesy of the annoyed senior mages.

She landed in the middle of the thousands of undead, causing a shockwave that knocked back everything nearby.

"I see…Kayla would certainly be good for this but I'm sure I can do better even if lightning isn't my forte."

While making the kind of statement one would expect from a demon of 'Pride', the woman moved her left hand and generated a pitch-black two-ringed magic circle, before infusing it with demonic energy.

She then snapped her fingers and muttered a small chant before generating another three-ringed green magic circle, but it was quickly dyed black by her ominous demonic energy.

"Wrath of Flame."

An omnidirectional wave of dark red flames spread out with Pride at the centre, sweeping through hundreds of undead monsters and setting them ablaze.

The undead mages who were proficient with water magic, even the undead rift mages of the water element all tried and failed to quench the demonic energy-infused flames that rapidly burned through all undead within a 300-metre radius that increased by the moment.

One of the high-ranking mages who were airborne noticed this and screamed at the nearby adventurers and knights who were rushing towards the opponent-less undead, to get the fuck out of the area.

When everything within 500 metres of Pride had been set ablaze, the high demon then activated the tier 3 wind magic spell she had prepared.

"I invoke a storm to shred apart all those who dare stand against me.

Demon Wind Magic: Corrupted Cyclone."

With a very Pride-like chant, the high demon's magic activated.

First, a wind-like sphere similar to Evan's elemental shield formed around her body, at the same time that a vacuum field that sucked everything within the range of her spell towards the centre.

In the next second, the vacuum field dissipated and the wind began rotating clockwise, around Pride's position, resulting in the formation of an enormous cyclone that could be seen from all across the battlefield.

The winds were so powerful that all the undead who dared to resist were torn apart by the centrifugal force.

If living beings were caught within this (which some unlucky few actually were), then breathing would become difficult inside the cyclone and as the surrounding debris was sucked into it, its destructiveness was only further increased.

Of course, breathing wasn't going to be their only problem as the spell wasn't called 'Corrupted' for no reason, but that's currently not important.

Now, adding the flames that had already spread across the area, and we now had a large flaming cyclone that would give even a grandmaster-level existence a run for their money.
