Black magic.

They used the magic with the demonic energy gained from the contract with the demon, negative energies gathered from others' suffering, and deeds are done against nature.

Though not at the level of demonic magic or the skills and abilities that demons use, this kind of magic is the most disgusting magic used by the black mage rakshasas of this world.

The black magic, though sounds like something of any normal fantasy novel, is something much different from the normal magic and low to mid-level magic skills people use.

It's not normal magic but somewhat more powerful than similar-tier magic spells, but in the end, it is still magic.

Sticky, dark, and disgusting magic.

Most mages loth this magic and mages who use it.

They hate it so much that the black mages aren't even considered mages by society.

And naturally, they aren't even considered part of humanity.

In this place where there was a ritual for the summoning of demons going on, anyone would just want to cold-heartedly kill this bunch with no hesitation.

Any strong person would just go against these fools and do their best to kill them as properly as possible.

But taking down fifteen (tier-3) black mages was no simple task at all!

Dark mages could work together like a single being, if not taken down in a bunch or at once.

Their simple (tier-1) spells could easily carry power equal to (tier-3) spells, they can easily cast (tier-3) spells with relatively low physical restrictions, unlike mages.

These were rakshasas, those who had forsaken humanity and fully become the subordinates of demons.

The restricted demons who can't properly interfere with the human realm on their own used them as their puppets to 'legally' come to this world and do things while still being under the rules of nature.

These people are the plague that is present in all parts of humanity, society, and culture. Hidden while wearing masks, or foolishly showing it far openly like these people.

The hidden ones are stronger, like this (tier-4) old mage priest. But they are far more sane and dangerous than this bunch.

This bunch was just disgustingly strong and dumb.

They were just insane lunatics and the person killing them was something so amazing that the ones watching this fight were genuinely surprised by his prowess.

They could guess he was just a young person like them and still, he was strong enough to just kill those fifteen mages in the blink of an eye like they were nothing before him.

His stealth, or more like a high magical skill that completely erased him from their senses, was amazing, unreal, actually.

Standing before someone and they have absolutely no idea that there is someone before them or anything is even abnormal in this place is just that amazing.

His attacks, that black flash of light, were even more amazing.

A quick moment, so quick that he traveled to his target in the flash of light, destroys his enemies, and endured all the possible recoil like it is nothing at all.

This person... he was strong and they could tell this without even considering his skills, techniques, and weapons.

He was physically strong enough to use this kind of swordsmanship as well as techniques.

He was mentally strong enough to naturally handle the recoil of the attacks and skills without any problem.

He was amazing as well as strange.

The light that had devoured the mage's bodies was even more strange and something very, very rare to consider as a possibility.

But that wasn't as amazing as the current fight that was going on right now.

The black mages were killed without resistance, their leader was alone in this place now, and the blood of black mages seeping out of the headless bodies was just increasing his rage.

This (tier-4) mage was now enraged, almost berserk, as he shot spell after spell at this person.

His attacks, the countless (tier-3) spells that were difficult to cast at the normal mage level, were made of their unique black energy.

They were different from normal magic that naturally felt weak, strong, and just normal. They had a strange sticky, murky, and unnatural feeling to them.

But they were definitely strong.

He used fire, electric, and ice attacks, most probably meaning he was a dual elemental mage with fire and water elements.

His spells were strong, but they were still disgustingly weird from any general point of view.The first reveal of this chapter happened through n(0)vel(b)(j)(n).

But the one they were pointed at, the person in black clothing, was as calm as he had been the whole time against them.

His eyes were sharp, calm, and cool, and there was no hesitation.

He was like a supreme beast who knew the attacks coming at him were nothing but mere sparks.

As the spells came close to him, he put his left hand on the sheath of his sword, pulled the sword with his thumb out of the sheath, grabbed the sword with his right hand, took an attacking stance, closed his eyes, took a deep breath, and...

-Click.

Another clicking sound echoed in the closed cave and the many spells coming at him at once... were cut in half by a slash of white light.

There was no blinding light this time, just a click and a crescent slash of white light that appeared before him after the clicking sound, and as this slash cut the spells in half... they just disappear.

A spell has a core, and that one attack had precisely destroyed the core of every spell coming at him.

And it was weird how the white light that barely touched just the spell was able to destroy the whole spell.

The core was definitely destroyed, but the attack only barely touched the core of some of the spells.

The power behind the spells was great enough that a single attack should never cut off them.

But it did happen, and the reason was the white slash of this dark-clothed person.

A powerful and strange attack that definitely shouldn't be anything normal.

But this thing didn't shock the already mad black magician, and he just continued attacking with a chaotic mind and almost red eyes.

His black eyes were starting to turn red, meaning he was going berserk for real now.

And a rakshasa going berserk was more complicated than a high-ranking beast going berserk.

Unlike the beast who just knew violence and lost their mind while berserk, the creatures like this dark mage just continued trying to destroy, kill, and survive until they achieved their goals for going berserk.

It was an innate characteristic of Rakshasas and it meant total chaos.

They were nothing less than half-demons in that state and the negative energy, demonic energy, and dead Mana they produced in the process also destroyed the surroundings.

Those things could happen and this area of the capital would be destroyed if that happens but.. this person in dark clothing had no plan of letting him go.

His normal, stoic golden eyes glowed with golden light, and.. a great pressure surrounded the whole cave.

The magic attacks were coming at him with the same swiftness as a while ago but, this time, he didn't do the same thing as last time and instead just took out his Katana from the sheath and held it with both hands.

The thin, sharp, single-blade Katana sword shined with golden light and changed into a two-edged, long sword.

And though this sword looked different from the previous one, they were the same swords.

A sword had changed its form and now he was fully ready.

The blade of the sword was shining with the same metallic silver glow as the previous sword and his eyes were looking at the spells coming at him as well as the mage with furious eyes.

The magic he was using was already unsightly in his eyes but, the appearance of this whole place was even more unsightly than that.

Holding the sword in his right hand, he looked at the spells and all these had happened in moments so, maybe the butterflies didn't make out some of it with their current lacking eyes.

His eyes were glowing with ferocious golden light and he was looking at the spells. These eyes were moving swiftly between spells, and the vines that appeared on his somewhat visible forehead were signs of deep critical thinking.

It was as if he was calculating at a lot faster speed than he was used to, almost as if using a skill that was stronger than normal.

But he was on the time. As soon as the spells were just before his person... he moved forward with a quick movement and his sword was covered by a black-white aura.

An aura that was white, as well as black. And this was balanced.

Two colors, perfectly harmonized, and with this sword covered in this strange aura, he just shot forward and.. in a blink of an eye, he reached the other side of this spell barrage.

And he didn't just stop at that point.

In the split second, he was on the other side, he took a firm stance, held his sword with nothing in his head, took a deep breath, intensified the black-white energy on his sword like fueling an already strong fire, and took a deep breath while closing his glowing stern gold eyes.

The black magician was a good mage despite being just a (tier-4).

To consistently cast these many spells at once was a huge thing and not many can do that.

It was a high-level casting rate and method, and right now; he was gathering all the demonic energy from the dead bodies at the same time as he cast these spells.

He was almost fallen to a berserk state after his precious plan to summon the great demons for the destruction of this part of the capital failed.

But that thing before him, the thing that even a (tier-4) black mage like him was worried about, was... dangerous.
