"Shhhk... Shhhk... Shhhk... Shhhk!"
This was the sound of a sharp blade slicing through the air at an incredible speed.
The twin magical swords in Lecty Eisenach's hands appeared to transform into countless flashes of light, flickering and enveloping Rozen, attacking with merciless precision.
Rozen felt his vision blur for a moment, and then his entire body was engulfed by a barrage of sword lights.
The relentless slashes were even more refined and lethal than when Lecty had defended against Rozen's barrage of earth bullets earlier.
This was a technique that the previous Lecty could never have performed.
Due to her personality, Lecty's slashes were often filled with hesitation, confusion, and fear, significantly reducing their power. Even when she successfully executed a technique, it never reached its full potential.
But now, Lecty unleashed her most powerful Eisenach-style twin sword technique without any hesitation.
The level of her swordsmanship surpassed the pinnacle of Lecty's life, reaching its ultimate form.
This was the pinnacle of the Eisenach-style twin swordsmanship — "Two Flashes, Ten Slashes."
"Excellent."
The ghostly glow in Rozen's eyes faded away, replaced by a determined smile.
Faced with the fastest sword, Rozen didn't retreat but instead advanced, closing the distance.
Telekinesis was applied to his body.
Several runes appeared on Rozen's limbs, embedding themselves into his hands and feet.
In that moment, Rozen not only used his "Telekinesis" ability but also cast a body-enhancing spell, employing the technique of "Rigid Body," bringing his physical abilities to the peak that rivaled those of a master who had trained for years.
Then, Rozen moved.
"Clang—!"
Amid the countless sword lights, the sound of metal clashing reverberated.
Rozen's magical sword seemed to pierce through the myriad of sword lights, as if he had precisely discerned their trajectories, following the shortest and closest path. He cut into the midst of the "Two Flashes, Ten Slashes," colliding with one of Lecty's sword blades.
As a result, one of Lecty's twin magical swords was deflected, and half of the enveloping sword lights vanished.
This incredible insight, angle, and counterattack directly neutralized the pinnacle of Lecty's Eisenach-style twin swordsmanship.
However...
"Clang—!"
Amid the sound of a sword cutting through the air, the sword in Lecty's other hand continued its unrelenting advance. It was as if the unbelievable scene before her didn't affect Lecty at all, as she coldly slashed at Rozen, this time aiming directly at his throat.
At this moment, Lecty had completely shed her previous hesitation and weakness, transforming into the most fearsome killing machine. Even though her opponent was the strongest Sky Wizard in Mistgun, she showed no hesitation or doubt.
This was the strongest Lecty Eisenach, the most powerful member of the E601 squad.
"What... what is going on?"
"...."
Misora Whitale and Rico Flamel, who had been practicing nearby, were finally drawn to the commotion. Seeing Lecty, who was relentlessly pressing Rozen and delivering lethal slashes with a blank expression, one was stunned, and the other showed a look of seriousness.
In contrast, Rozen seemed as if he had been prepared for this all along. He slightly tilted his head back, narrowly avoiding the magical twin sword that was slicing towards his throat.
The cold edge of the blade brushed against the skin of Rozen's throat.
Yet, after delivering such a slash, Lecty suddenly pulled back.
"Zing!"
In the next instant, the twin magical swords in Lecty's hands began to emit a brilliant light.
The light came from the runes inscribed on the magical swords, which started to glow as mana was infused into them.
Seeing this, both Misora and Rico cried out in shock.
"That's...!"
"A battle skill...!"
— "Battle Skill."
This was a special skill that combined magic with personal technique, utilizing the magical alchemic weapons as a medium to unleash a deadly strike, similar to the Noble Arts used by Blazers. It could play a crucial role in combat.
Most Sky Wizards could use battle techniques, utilizing their magical alchemic weapons to demonstrate extraordinary combat power.
In short, these were the ultimate techniques of Sky Wizards.
And now, Lecty was using the Eisenach-style twin sword battle skill.
"Thousand Force."
Lecty, with a blank expression, whispered the name of the battle skill and instantly closed in on Rozen. The twin magical swords in her hands transformed into a porcupine's quills, unleashing countless thrusts in the blink of an eye.
Those thrusts turned into beams of light, with an attack frequency so dense that it was terrifying.
It wasn't a matter of attacking ten times in an instant, nor a hundred times, but a true, literal thousand times in an instant. The twin magical swords in Lecty's hands were thrust forward with an incredible frequency.
Suddenly, Rozen felt as if the skin on his entire body was about to be stripped away.
So, Rozen acted without hesitation. He knew that if he didn't, Lecty's attack would undoubtedly leave him riddled with wounds, dead on the spot.
But...
"It wouldn't be fun otherwise."
Rozen's figure swiftly retreated like a phantom, using telekinesis to manipulate the ground as he retreated. A large boulder rose up, intercepting the countless thrusts from Lecty.
"Boom—!"
The massive boulder couldn't withstand even a second; it was shattered by the countless thrusts, turning into a shower of fragments that scattered in all directions.
And Lecty, undeterred, continued her relentless pursuit.
"Eisenach-style twin sword battle skill — 'Sky Slash.'"
Lecty raised her twin blades and spun them rapidly.
"Boom...!"
As Lecty spun, the atmosphere was completely stirred up, transforming into a vortex-like whirlwind that spiraled towards Rozen.
In response, Rozen's figure abruptly halted.
"Zing!"
In his hand, the magical sword was enveloped in what seemed like an infinite amount of telekinesis energy, extending into a blade of pure telekinesis, radiating a blinding light.
This was "Magic Resilience," a technique of a magus at the seventh rank, after mastering it to the extreme, could extend their telekinesis energy into a blade.
After many years, Rozen finally used this technique once again.
And he combined it with the most powerful single-handed sword skill from SAO.
"Vorpal Strike."
Rozen's figure suddenly lunged forward, like a spear piercing through the air. The magical sword, enhanced with "Magic Resilience," was then swung with great force towards the oncoming whirlwind.
"Boom—!"
With a deafening roar, the telekinetic spear struck the vortex head-on, dispersing it completely.
Countless wind currents and shockwaves swept through the surroundings, kicking up a cloud of dust that blotted out the sun.
Rozen and Lecty had suddenly engaged in a fierce battle.
It was a fight that left everyone breathless.
