Isekai Adventure in the Dimensional Cube

"———!"

Struggling up from the pile of rubble, Jill's consciousness hadn't fully cleared yet. He was only feeling the pain in his body and instinctively seeking blood, when suddenly, an incredibly terrifying killing intent locked onto him.

The intensity of that killing intent caused waves of bone-chilling cold to instantly rise from the soles of Jill's feet, shooting up to his crown, which snapped his dazed consciousness from the pain to full alertness.

In this moment of clarity, Jill immediately saw Reiger, wrapped in gales, his robe fluttering wildly in the wind, making a whistling sound.

The look in the opponent's eyes and the relentless sense of lethal threat emanating from him finally made Jill feel fear.

Although Jill was under the influence of the demon swordsmanship and addicted to blood, he had not completely lost his reason.

Three years ago, when all the Demon Swordsmen were besieged by knights sent from various countries and faced with life-or-death situations, while others almost went mad with excitement and rushed out to fight bloodily against the knights, Jill, driven by an ominous instinct, allowed his fear to overcome his craving for blood and the desire for power, choosing instead to flee in disarray.

As a result, Jill was lucky to have survived the siege and continued to live up to this point.

Over these three years, Jill adhered to the principle of keeping a low profile, living in the wild, subsisting on animal blood, battling magical beasts, both easing his thirst for blood and gradually growing stronger.

It wasn't until he encountered Eredman in the wild and saw the strong knights around him that Jill could not suppress his craving for human blood and decided to indulge just once.

However, Jill did not act immediately to kill Eredman on the spot for his blood.

Since he decided to indulge, Jill naturally hoped for as much of this "feast" as possible.

Thus, Jill pretended to follow Eredman, actually only intending to use this as a chance to infiltrate human cities and hunt there.

In the week before the War Festival started, Jill often went out, seemingly wandering around the city, but in reality, he was secretly hunting humans, voraciously drinking the blood of thugs and thieves lurking in the darkness.

Once the War Festival began, with a large crowd converging in the training grounds, Jill would indulge in unrestrained slaughter, satisfying himself thoroughly before escaping Wendini and retreating back into the mountains to evade the pursuit of the kingdom's knights.

His first target was those strong competitors entering the duels.

Like Reiger Brillhaut, the Tactical Level Magician.

Like Yuri Franzel, the Strategic Level Magician.

One step at a time, Jill planned to take down the strong first, which would not only eliminate future threats but also strengthen himself with the blood of these powerful individuals. Then, he would hunt the weaker ones gradually, feasting and swiftly increasing his own power, potentially leaping into the rank of a Sword Saint, becoming a Demon Sword Saint.

This was why Jill had patiently waited to make his move after entering the arena.

Unfortunately, he was unlucky.

With his strength, whether facing Yuri, Marilyn, Ai En, Ian, or others, he could have caught them off guard and killed them instantly, their blood splattering on the spot.

However, his opponent, ironically, was the only one in the entire venue with strength comparable to Lv.6, and who was proficient in both sword techniques and magic—Reiger.

After being wounded by Reiger and driven by the instinctual excitement of Reiger's strength, Jill finally could no longer contain his thirst for the blood of the strong and fell into a semi-uncontrolled state.

But now, facing Reiger's undisguised killing intent and terrifying aura, Jill's rationality returned on the spot, and a fearful emotion also surged back into his heart.

But it was too late.

"Bang!"

Just as fear emerged in Jill's heart, the ground beneath Reiger exploded, and he himself suddenly vanished from the spot.

"———!?"

Jill's heart skipped a beat, yet he still, driven by his sense of the blood aura, detected Reiger's whereabouts.

"This way!"

Without thinking, Jill swung his blade to the right, unleashing a torrent of blood-red magic power that howled and overturned the atmosphere as it sliced toward the figure that suddenly appeared there.

Reiger, however, ignored the slash completely, lunging forward and closing the distance in an instant.

"Clang!"

Jill's forceful slash landed on the gale swirling around Reiger's body and was deflected cleanly, just as before.

"Pffsch!"

At that moment, Reiger launched a slashing attack, incredibly fast, as if slicing through space and time, it cut through Jill's shoulder, causing his flesh to burst open and blood to splatter.

"So fast!"

Jill's pupils shrank.

Reiger's slash was much faster than Jill's reaction could keep up, far faster than before.

No, it wasn't just the attack speed, even the movement speed had increased significantly.

"Pfft—Pfft—Pfft—"

Amidst a series of tearing sounds, Reiger's figure blurred like a colorless, invisible wind around Jill, flickering back and forth, sweeping out slashes aimed at every part of Jill's body, causing skin and flesh to burst open and blood to spill profusely.

"Ahhhhhhhhhh!"

Jill roared furiously, his blade in hand slashing wildly with blood-red magic power, creating sonic booms and loud whooshing noises that resonated frequently, but he never managed to hit Reiger, who dodged everything with astonishing speed.

Jill's missed strikes could only land on the ground and the walls, causing streaks of blood-red sword light to streak across, leaving cracks everywhere they touched.

Stones and dust were thrown up once again, turning the entire training arena into a storm of flying sand, adding to the tumultuous winds, creating an almost tempestuous atmosphere.

It was then that Jill suddenly realized the weapon in Reiger's hand had changed.

The weapon he now held was no longer a bright silver short sword but a somewhat dim silver long sword.

The long sword was thin as a cicada's wing, nearly transparent at the blade, and looked beautiful and noble—not at all like it was made of metal, but rather like a piece of clear, pristine crystal.

Yet this sword, which looked more like a piece of art than a weapon, exhibited a surprising sharpness and might in Reiger's hands.

"Pfft—Pfft—Pfft—"

Reiger, wielding the Fool's Sword, pushed his "Agility" skill to the limit, further enhanced by Wind Spirit Swift Walk and Lamu, reaching speeds that even Jill at Lv.6 couldn't react to.

Even before returning to the continent of Akasha, Reiger's strength had already surpassed Ais, beyond the Sword Princess Ais Wallenstein who was said to be able to battle beyond her level, competing with Level 6s.

With his full power unleashed, Reiger had confidence that even against the top of Level 6 fighters like Finn, Revilia, and Grace, he would not be far behind.

Although he had only recently reached Level 5, his accumulated high potential from several levels and multiple combat development abilities allowed him to surpass Ais, who was at the top of Level 5, even without using magic.

Now, Reiger used Lamu, which significantly boosted his "Agility" protection magic, and he also used the exceptional Wind Spirit Swift Walk, along with the Fool's Sword; dealing with Jill had ceased to be a challenge.

Therefore, amidst the blazing speed of his sword light, Jill endured a brutal beating; his body seemed to explode, continuously spraying blood and suffering wounds, becoming horrifically scarred.

"Ahhhhhhhhhh!"

Faced with a hopeless situation, Jill exploded with power, the blood-red magic power on his body surging, boosting his strength to a new level, finally catching up with Reiger's speed to make a reaction.

However, Reiger ignored Jill's counterattacks entirely, letting the bloody strikes fall one after another on his body without blocking or dodging.

But, with Lamu enhancing his "Endurance" and Wind Spirit Swift Walk's wind protection, even Jill's ultimate strikes were repelled one by one. Only a few managed to penetrate the wind's defense and land on Reiger, but they only left shallow wounds, causing minimal bleeding—nothing more significant than that.

In contrast, Reiger's slashes became faster and more ferocious, not only tearing Jill's flesh but also nearly shearing off all the flesh on his body, with several cuts on his shoulders and thighs deep enough to reveal bone.

Even so, Reiger did not cease his relentless assault on Jill, seemingly intent on grinding him into a bloody pulp, the speed and ferocity of his attacks undiminished, constantly slashing, slashing, and slashing!

The display, reminiscent of a merciless executioner, caused many in the audience to show looks of horror, with some even closing their eyes.

Finally, Jill broke down.

"Get out of my way!"

With a furious roar, Jill struck the ground with his sword, shattering the earth and creating a violent shockwave and billowing dust.

With that, Jill managed to push Reiger back and, without a second thought, turned and began to flee desperately.

In response, Reiger's eyes remained cold as he rushed through the thick dust, raising his hand as he chased Jill, who was fleeing with his back turned.

On it, a red surge emerged.

Reiger finally unleashed his trump card.

When the red surge was blasted out like a storm, splitting the earth and the air, catching up with Jill, it was too late for him to react.

"Boom!"

The red surge hit Jill, engulfing him completely.

"No—!!!"

Jill let out a despairing scream and was then disintegrated within the red surge, much like a monster from the underground city stripped of its magic stone, turning into ash and vanishing without a trace.

The inhumane torment thus came to an end.

Reiger dispersed the wind and deep green glow around him, staring coldly in the direction where Jill had disappeared.

"It seems you didn't even deserve to be reduced to a blood mist."

The Festival of War thus drew to a close.

The victor was, without a doubt, Reiger.
