"Clang!"

"Crackle... crackle..."

A fierce, whistling wind howled across the icy landscape of Freezing Hell.

Two months had passed.

A blindfolded figure stood tall amidst the frozen wasteland, his silver hair flowing like a tempest, his robes fluttering with an aura of unshakable confidence.

Wilhelm, imposing and resolute, gripped the Shichiseiken. With a fierce slash, he clashed against a formidable prisoner—a warrior he had freed from Eternal Hell.

This man, possessing Conqueror's Haki and once bearing a bounty exceeding 800 million Berries, now stood as his opponent.

Black and red lightning crackled between their strikes, snaking through the air like dragons, radiating power and creating shockwaves that rippled outward.

The immense wind pressure made it nearly impossible for the onlookers to keep their eyes open, leaving them stunned by the sheer spectacle.

"Conqueror's Haki clash?"

From a distance, Shiryu of the Rain watched with a mixture of admiration and hunger for battle. His eyes gleamed with fiery determination. "It's insane how he's relying solely on Observation Haki to fight without his sight."

"No doubt about it," added 'Thousand Faces' Johnny, flashing his yellowed teeth in awe. "In just two months, the progress is unbelievable! Even blindfolded, Wilhelm isn't pushed far enough to use his Transfer-Transfer Fruit abilities."

Johnny gestured toward the "Ghost Swordsman," Wilhelm's current opponent.

"That guy had an 847-million-Berries bounty back in the day. Sure, he's not at his peak after years in Impel Down—tortured, underfed, and denied proper medical treatment.

He's old, worn out, probably at 70 to 80 percent of his prime. But even so, Wilhelm hasn't needed his moon lion transformation or that terrifying electric shock technique of his to hold the upper hand."

The more Johnny observed Wilhelm, the more unfathomable the young warrior seemed.

Wilhelm wasn't just tough—his body was monstrous, invulnerable, like steel wrapped in iron. On top of that, his Transfer-Transfer Fruit made him nearly impossible to pin down.

And then came the revelation that had left them all speechless: Wilhelm possessed Mink blood.

The realization sent chills through everyone. Not only could Wilhelm unleash powerful electricity, but he had also shattered the limitations of the Minks' natural transformations.

While most of their kind required the full moon to awaken their wild, primal state, Wilhelm could transform into the legendary moon lion at will.

Shiryu hadn't yet seen this transformation in action, but he didn't need to. Just imagining the overwhelming combat power Wilhelm would display in that form was enough to make even a seasoned warrior shudder.

Over the past two months, Wilhelm's training had been relentless, bordering on madness.

Out in the frozen wastelands of Freezing Hell, Wilhelm honed himself daily, endlessly sharpening his Haki and refining his skills.

What made it extraordinary wasn't just the training—it was how he pushed himself beyond all limits. Blindfolded, Wilhelm relied solely on his Observation Haki to react and respond.

Shiryu, wielding a Gatling gun forged by Dr. Hawkins using his Munch-Munch Fruit abilities, would rain down endless bullets, amplified to insane speeds and sizes through the power of Shiryu's Momo-Momo no Mi.

Bullets, moving faster than the eye could follow and striking harder than cannonballs, filled the air like a storm.

Wilhelm had two options: dodge them with pure Observation Haki or intercept them with Armament Haki-coated strikes.

Sometimes, he dodged gracefully, weaving through the onslaught. Other times, he stood his ground, fists or palms coated in Haki, deflecting and destroying incoming rounds with terrifying precision.

The training didn't end until either Wilhelm collapsed from exhaustion or Shiryu's own stamina gave out from using his fruit's power continuously.

Wilhelm refused to rely on his Transfer-Transfer Fruit. Instead, he faced the deadliest prisoners of Freezing Hell and Eternal Hell, forcing himself to adapt and grow stronger with each confrontation.

At first, Wilhelm had struggled, barely keeping up in these battles. But now?

Even against the Ghost Swordsman—a legendary figure whose strength rivaled his prime years—Wilhelm remained calm and dominant.

His mastery of swordsmanship and his control over Haki had reached astonishing new heights.

Every swing of his Shichiseiken, every strike charged with black and red lightning, reflected the sheer intensity of his growth.

"He's not human," Shiryu muttered under his breath, the corner of his mouth twitching as he observed the scene. "This is the kind of monster who could shake the world."

"Scrape..."

"Clang!!"

"Clang!!"

The relentless clash of swords echoed across the battlefield, the sharp sound piercing the frozen air.

Frenzied sword energy erupted, tearing the land apart in chaotic devastation. The ground lay scarred with deep, crisscrossing fissures, impossible to ignore.

Even the falling snow and ice failed to cover the destruction, leaving it exposed—a testament to the ferocity of the battle.

"Clang! Clang! Clang!"

The relentless sound of colliding steel made onlookers wince, the sheer intensity gnawing at their nerves.

Wilhelm moved like a phantom, his figure swift and fluid, radiating an aura of calm control.

His movements seemed effortless—dodging lethal strikes mid-air with precision and ease. When necessary, he swung his Shichiseiken, blocking the "Ghost Swordsman's" vicious attacks with unerring accuracy.

His Observation Haki, now honed to terrifying levels, had rendered his blindfolded state irrelevant.

With a perception that bordered on omniscience, Wilhelm's awareness extended in all directions.

No strike, no matter how cunning or unexpected, could escape his razor-sharp, almost 360-degree detection.

As time wore on, the battle began to shift.

The "Ghost Swordsman," though formidable, showed signs of wear. His years in Impel Down had taken their toll—despite the healing of his natural teeth, age and prolonged imprisonment had dulled his once-peerless strength.

Sweat poured from the veteran's brow as his stamina dwindled. His attacks lost their edge, becoming slower and less coordinated.

In stark contrast, Wilhelm remained unyielding, his movements as sharp and measured as ever.

The Shichiseiken in Wilhelm's hands moved like lightning, weaving a relentless and overpowering web of attacks.

The "Ghost Swordsman" found himself increasingly overwhelmed, forced to abandon any offense and focus solely on desperate defense.

One near miss followed another.

Cuts and wounds multiplied across his body, blood flowing freely and staining the snow beneath his feet.

"Keng!"

In a blink, Wilhelm's calm demeanor turned deadly. With terrifying precision, he dodged a blade aimed at his cheek and countered with astonishing speed.

His Shichiseiken, wrapped in formidable Armament Haki, unleashed a sinister and malevolent energy unique to the weapon itself.

The dark green blade cleaved through the air with unstoppable force, colliding with his opponent's weapon.

The sheer power of the blow sent the "Ghost Swordsman" stumbling back, his hands trembling as pain shot through his wrists.

The alloy blade in his hands—a masterpiece forged by Dr. Hawkins and strong enough to rival most famed swords—nearly slipped from his grip.

To his shock, visible cracks now marred its edge, despite being coated in his own Armament Haki.

Meanwhile, Wilhelm's Shichiseiken remained unscathed, its edge gleaming ominously.

The power gap between them had never been clearer. The "Ghost Swordsman" stared at Wilhelm in disbelief, his pupils shrinking. But there was no time for shock.

"Hey—!"

A thunderous slash tore through the air, roaring toward him like a flying dragon with fangs bared.

"What!?"

Covered in blood, his body trembling with exertion, the "Ghost Swordsman" gritted his teeth. Though overwhelmed, his eyes burned with unrelenting madness.

"Hell Ghost Slash!"

With a ferocious cry, he mustered every ounce of strength left in his battered body, unleashing a blazing slash of energy to meet Wilhelm's attack head-on.

The two monstrous waves of sword energy collided with a deafening "BOOM!"

Light flared, blinding and unbearable.

A storm of wind, ice, and debris erupted from the collision, ravaging the battlefield and swallowing the combatants in chaos.

But Wilhelm's figure moved like a bolt of lightning, impossibly fast.

Before the "Ghost Swordsman" could recover, a flash of cold steel streaked toward him.

"Chi!"

The next moment, his world turned upside down.

For a fleeting second, he saw his own headless body standing in the snow, sword still in hand.

Darkness consumed him.
