Isekai Adventure in the Dimensional Cube

However, after more than a month, having regained my true name and with my power surging, the opponent could still handle the battle with me so effortlessly. How could Bagster not be astonished?

I’ve become stronger, but the opponent seems to have grown even stronger, and they’ve become unmatched.

"What happened? Why did you suddenly become so strong?"

There was no resentment in Bagster’s tone, but rather a glint of a predator’s desire, as if she saw delicious food becoming even more tempting.

"A lot has happened."

Reiger couldn’t help but recall his experiences after leaving the Fairy Country’s Lostbelt, feeling a bit wistful.

However, he naturally wouldn’t recount what he had been through here.

"Although it wasn’t my original intention, returning this time to settle things with you all isn’t so bad." Reiger smiled at Bagster and said, "You’re probably stronger than Lancelot before he regained his true name, right?"

"So, this is probably your last chance to possibly defeat me."

"I will keep getting stronger."

"If you can’t defeat me this time, you won’t have another chance in the future."

Reiger’s words did not make Bagster angry; instead, they intensified her predatory instincts.

She was originally a fairy who followed the principle of survival of the fittest.

The strong can protect the weak, but they can also trample the weak and hunt stronger ones.

Consuming the flesh and blood of the strong to become even stronger is not only Bagster’s instinct but also her desire and yearning.

Therefore, Reiger’s words did not anger her; instead, they made her gleeful at the hunt.

"I will defeat you, devour you, and then become even stronger!"

Saliva trickled from Bagster’s mouth, making her appearance extremely ferocious.

"If I lose, don’t expect me to let you go, Reiger Brillhaut!"

Overcome by instinct and desire, Bagster finally lost her rationality.

Even though she knew the person in front of her was the queen’s husband, whom she admired for his strength, in her current state, she could no longer hold back.

"Prepare yourself!"

Bagster, engulfed in fierce black flames, hurled Reiger away and casually slashed, unleashing a torrent of soaring flames towards Reiger.

"Bone-Burning Sun!"

Reiger, while being hurled away, also casually slashed, splitting out a large vortex of flames that collided with the incoming torrent of flames.

"Boom!!!"

A thunderous explosion echoed, and the flames surged like a violent explosion, turning everything in its path into a sea of fire, burning fiercely.

"Hmm?"

Reiger, who blocked Bagster’s flame attack, immediately stabilized his stance and sensed something unusual beneath the ground.

"Crack—"

Suddenly, the ground fractured, rising rapidly.

"Howl!"

"Howl!"

Several black hounds emerged from beneath, their mouths open wide, lunging at Reiger and biting his arms, legs, and back.

"Boom!"

Flames erupted from Reiger’s body, swirling around like a bladed wind.

This wasn’t the Sun Breathing’s sword style, but the fifth form of Moon Breathing—[Lunar Disastrous Vortex].

As the only defensive technique within Moon Breathing, this sword style can be unleashed without drawing the sword. As long as one can revolve themselves, it creates a massive vortex-shaped blade wind around them, repelling enemies that charge close.

At this moment, Reiger unleashed this sword style using Sun Breathing, transforming [Lunar Disastrous Vortex] into [Solar Disastrous Vortex].

This wasn’t a mixed breathing technique but purely using Sun Breathing to perform a Moon Breathing sword style.

As his strength increased, Reiger became more adept at using breathing techniques, now able to casually execute various forms of major breathing techniques without mixing them, displaying the characteristics of each sword skill with the supreme Sun Breathing, wielding various forms at will, clearly having honed the art of breathing to perfection.

For current Reiger, he no longer needed to intentionally switch breathing techniques. The essence of breathing techniques naturally imbued in each breath, and he could effortlessly unleash various sword skills with each movement, with the body instinctively exerting them even without deliberate intention.

In simpler terms, this state could be described as Unity of Man and Sword or Unity of Heaven and Man, integrating "skill" fully into oneself, no longer confined to its original form.

Now, Reiger can breathe however he wishes, as his breathing is the breathing technique, requiring no deliberate adjustment in breathing method, embodying an entire breathing style himself.

Naturally, he can execute sword skills at will, with no obsession over which breathing technique can use which sword style, using Sun Breathing to execute the style of Moon Breathing is fine, or using Moon Breathing to perform the style of Thunder Breathing too, even without any breathing techniques, he can perform various styles effortlessly.

Embodying myriad skills, every swing and slash is a technique.

This is the true pinnacle of swordsmanship.

"Boom!" "Boom!" "Boom!" "Boom!"...

Suddenly, the explosive fiery wind deterred each black hound clinging to Reiger, igniting them until they were burned to nothingness without leaving even a bone.

"Clatter, clatter—"

Immediately after, chains of crimson shot from the other side of the sea of flames, like snakes carried by foul winds, also biting towards Reiger.

"Swish!"

This time, Reiger didn’t intend to confront them head-on but dodged deftly, swiftly retreating with a faint whistling sound, evading the incoming chains of crimson.

"Boom!" "Boom!" "Boom!" "Boom!"...

Chain after chain struck the place where Reiger originally stood, shattering the ground he passed over.

For a moment, dust filled the air, fragments soared everywhere, and the sea of flames seemed overturned by the crimson dragons, rising and surging incessantly, forming an even larger flaming storm.

"Clang—clang—clang—clang—"

Closely followed by countless crimson chains, Bagster wielded a cursed sword enveloped in deadly black flames, appearing again to pursue Reiger, swinging the cursed sword violently, clashing incessantly with Reiger’s raised black blade, producing continuous booms.

"Don’t run!"

Bagster shouted, nearly losing her reason.

Reiger’s body suddenly came to an abrupt halt, surprisingly not retreating, charging directly towards Bagster with translucent gleams in his eyes, swinging the heaviest slash so far.

"Clang!!!"

The resounding clash erupted, accompanied by a fierce shockwave.

The black blade, wrapped in flames, cleaved the incoming cursed sword, forcing Bagster to retreat.

"What?"

Bagster’s pupils shrank.

"Sizzle—"

But, the black blade in Reiger’s hand was no longer burning with flames but flickering with black sparks.

"[Dimensional Slash]."

In the next moment, the black blade flickering with black sparks slashed downward abruptly, slicing through air and black flames.

"Clang—"

A dull heavy sound occurred, and the cursed sword reflexively raised by Bagster couldn’t withstand this effortlessly heavy slash, getting severed along with the flames.

"Puchi!"

Soon after, the sound of flesh being torn by a sharp instrument followed.

A splash of blood spread swiftly, dyeing the ground in red.
