Isekai Adventure in the Dimensional Cube

Yuri discovered something that others had noticed as well.

When Jill's body started to emit that layer of blood-red magic power, and he grew increasingly stronger under its enhancement, many people noticed the problem with the swordsman.

"So that's how it is, that person is a Demon Swordsman who has mastered the Demon Sword Technique?"

The noble young man from the royal capital revealed an expression of sudden realization.

"Demon Sword Technique?" The Attendant, hearing his master's words, immediately showed a shocked expression, saying, "The technique that caused the turmoil three years ago?"

"Exactly," the noble young man nodded and said, "That's the one."

This was a matter that had even been widely spread among the common folk.

Just three years ago, a group of very strange swordsmen suddenly appeared in various countries across the continent.

These swordsmen were all strong, not only due to their genuine Swordsman-class capabilities, but also without exception, they all had crimson eyes and used a weapon similar to a sword. When they fought, they would trigger a kind of blood-red magic power, and under the enhancement of that magic power, they would grow stronger as the battle progressed, rendering them nearly invincible in combat, rarely meeting any match.

Such a group of abnormally powerful and strange swordsmen inevitably attracted the attention of the major countries, which sent people to contact them, intending to uncover the secrets behind their eerie strength.

Then, at some point, the secret was revealed.

It turned out that these swordsmen were so strange and powerful solely because they had all mastered a very special sword technique.

Ordinary sword techniques, whether low-level or high-level, or even special-level, were practiced by using breathing techniques to stimulate the magic power within the body, allowing the individual to absorb magic power to refine the body and become stronger and stronger.

But this special sword technique was different.

When practicing this technique, the swordsmen did not refine themselves by absorbing the magic power within their bodies, but by absorbing the blood of those who died under their swords to strengthen themselves.

In other words, the swordsmen who had mastered this technique did not increase their power through training but through slaughter.

The more people they killed, the stronger they became.

The stronger the people they killed, the more powerful they became.

This was the sword technique that had once caused a great uproar in the Akashic Continent—the Demon Sword Technique.

This technique was suitable for anyone to practice; as long as one was willing to slaughter and absorb blood, there was no worry of not becoming stronger.

With such a special sword technique, that group of swordsmen caused troubles everywhere, committing countless killings, yet each one became stronger than the last, without a single one being weaker than a genuine Swordsman.

"The swordsman currently battling Reiger Brillhaut fits almost perfectly with the characteristics of the Demon Swordsmen mentioned in the rumors; he uses a weapon similar to a sword, his eyes are crimson, and he has the enhancement of blood-red magic power during battle, which allows him to grow stronger as the fight continues. It's certain that he is a Demon Swordsman who has mastered the Demon Sword Technique,"

the young noble declared with certainty.

But the Attendant was suddenly filled with doubt and uncertainty.

"But weren't that group of Demon Swordsmen eradicated already, and even the Demon Sword Technique destroyed by the countries?"

Indeed, both the Demon Swordsmen and the Demon Sword Technique were no longer existent in this world.

The group of Demon Swordsmen was just too crazy, too fond of killing, creating many disasters. Therefore, the major countries sent out their knights, who carried out a campaign against these Demon Swordsmen, ultimately succeeding in completely eradicating these dangerous elements.

Thanks to this, the Demon Sword Technique also fell into the hands of the major countries, but they unanimously decided to destroy it.

The reason was nothing else but the fact that the sword technique was too dangerous and the side effects too terrifying.

Those who practiced the Demon Sword Technique would create countless acts of slaughter in their lives to become stronger.

Of course, if it were just this, it wouldn't have been enough for the countries to destroy it.

The problem was that after practicing this Demon Sword Technique, the practitioners would become more and more desperate for blood, more and more fanatic, to the point where they could replace meals with blood three times a day.

Practicing this sword technique would cause an addiction to blood.

The blood of the stronger the person, the more it would attract them.

With such a side effect, naturally, countless people steered clear of it.

The countries were also worried that people, in pursuit of power, would recklessly practice this sword technique and become Demon Swordsmen who would disturb the peace of the land, so they decided to destroy it.

As such, theoretically, the Demon Sword Technique and the Demon Swordsmen who had practiced it should no longer exist.

However—

"You actually believe it when others say it's destroyed?"

The noble young man countered with a rhetorical question, leaving his Attendant speechless.

Indeed, just because others say it's destroyed, does it mean it truly is?

Given how unique this sword technique is, allowing one to effortlessly become a Swordsman-class expert, even if it has side effects, how many people would willingly destroy it?

Not to mention that the ones making such declarations were the great countries of the Akashic Continent—can we truly know what the upper echelons of a country do, whether they say one thing and do another?

This special sword technique, which strengthened one through killing, was coveted by many with ambition, and others wished to use it to cultivate a powerful killing force to eliminate dissidents.

Considering this, the so-called public statements of the destruction of the Demon Sword Technique by the various countries should be taken with a grain of salt.

"Moreover, no one knows whether among those Demon Swordsmen who were rounded up, there were any who escaped, becoming survivors."

The noble young man shook his head, watching the increasingly frenzied Jill, his eyes narrowing slightly.

At this moment, Jill truly was nearing madness.

"Give me blood! Give me blood! Give me your blood aaaaah!"

The crimson hue in Jill's eyes, aglow with blood-red magic power, had truly become nearly indistinguishable from a demon's eyes.

Inside, there was no trace of reason, only an unending thirst for the blood of the strong and the ultimate pleasure of slaughter.

"Clang—"

When a clash, louder and more intense than any before, sounded, Reiger, who had been defending against Jill's fierce assault, was finally sent flying.

His feet scraped the ground, his form uncontrollably retreating backward, plowing a deep groove along the way, sending fragments and pebbles flying chaotically.

"Hahaha!"

Jill laughed maniacally, exhilarated, like a demon emerging from hell, giving Reiger no time to catch his breath, shattered the ground, and rushed forward like a bolt from a crossbow.

Seeing this, Reiger knew he had to get serious.

"[The relentless sun of the skies, everything escapes your body.]"

"[Burst forth, the Armor of the Laurel Tree.]"

"[Lamu]."

Following the incantation that greatly strengthened "endurance" and even more so "agility," a deep green radiance emerged around Reiger.

"[Awaken (Tempest)]."

Super Short Spell enhanced magic of the breaking class with wind attributes was used again by Reiger, showing off its brilliance for the first time in this otherworld, unlike the Earth Mistake World.

The atmosphere then started to surge, transforming into streams of air that coiled around Reiger.

The howling wind, mixed with deep green brightness, turned the originally invisible and colorless force of wind into a deep green shade.

Reiger, wrapped in the deep green tempest, confronted Jill, whose body oozed with blood-red magic power.

"Boom—"

In the astonishing clamor of their collision, shockwaves spread out like an explosion, blowing away sand and dirt and shattering the ground, sending innumerable fragments flying.

"What!?"

"Ah!"

"Stones, stones are flying over here!"

In the spectator stands, people watched as fragments mixed with shockwaves flew towards them, immediately plunging them into panic.

Fortunately, these fragments and shockwaves were all blocked by a suddenly appearing transparent barrier.

Indeed, it was the protective barrier activated within the arena.

The barrier intended to protect the spectators finally served its purpose.

Seeing this, many people breathed a sigh of relief and calmed down.

They were then immediately captivated again by the battle in the arena, stripped of all their attention.

"Clang clang clang clang clang—"

In the shattered arena, two swordsmen, surrounded by deep green winds and blood-red magic power, swung their blades at a terrifying speed, making the sword lights flash, collide, vanish, and scatter in all directions.

Reiger's sword, the Hermit's Blade, had become so blurred that its form could not be seen; along with his movements, it transformed into ceaseless sword lights, slashing at Jill's entire body with the speed of a whirlwind.

Jill, in return, cleaved out blood-red sword lights. Although fewer in number than Reiger's, each one aimed straight for the throat, heart, head, or even the eyes of Reiger, targeting vital points, each capable of being lethal.

This made Reiger seem truly enraged, his expression and eyes remaining calm, but, he stopped defending against Jill's slashes, allowing them to cut into his body. The Hermit's Blade then pierced through countless sword lights, slashing brutally at Jill.

The crimson in Jill's eyes deepened as if spurred by Reiger's reckless behavior. He too, in turn, ignored Reiger's slash, his blade breaking the sound barrier, cutting towards Reiger's head.

This act, akin to mutual destruction, did not actually lead to both sides perishing.

"Ching—"

Jill's retaliatory blade struck Reiger's forehead fiercely, but was deflected by the wind coiling around Reiger, sparking a burst of fire, causing no damage.

"What—!?"

Jill's crimson eyes suddenly narrowed.

And by that time, Reiger's attack had already landed on Jill.

"Puchi—puchi—puchi—"

Sounds of flesh tearing arose, resulting in blood splattering.

Reiger's slashes landed on Jill's cheek, side, thigh, shoulder, and close to the major arteries, mercilessly cutting them open.

Jill, with fresh wounds all over his body, staggered as if struck by lightning, his body convulsing, retreating violently.

"[Arc-shaped Beam]."

Reiger quickly invoked a Super Short Spell, gathering a more potent blast magic, directing a life-sized arrow of light towards Jill.

"Roar—"

The next second, an explosion shook the entire arena, and flames surged with the shockwave, reaching the spectator stands.

The transparent barrier trembled suddenly.
