RUMBLE—CRACK!!!
A titanic bolt of lightning, bridging roiling storm-clouds and shattered earth like a spear of divine judgment, violently ripped the battlefield apart!
Raging ions and cyclonic wind formed a fleeting, insurmountable wall, forcibly splitting the two combatants who had been locked in struggle until now.
On this side of the storm, Rayleigh drove his long-sword deep into the scorched ground, barely keeping himself upright.
He was drenched in blood; what had once been decent clothes were now tattered rags glued to countless fine or gaping wounds.
Every labored breath carried scorching pain and the iron tang of rust, chest heaving.
He lifted his head, gaze piercing the chaotic arcs of electricity and dust to look across the storm.
There stood Luffy in the sky—stable, intact, save for a few tatters and some old, dried blood; virtually unscathed!
That boundless vitality, despair-inducing, made the half-day clash—enough to wipe a nation off the map—feel to him like a merely satisfying warm-up.
"—Whew…!!"
Rayleigh exhaled a blood-flecked breath, a weary, admiring, utterly helpless smile tugging at his lips.
He twitched a corner of his mouth; though hoarse with exhaustion, his voice stayed clear:
"Fighting a monster whose life-force is even more absurd than a Mythical Zoan, I finally know what it feels like to punch cotton—no, an ever-bouncing Sea Stone spring!"
Infuriating! Even his time-worn calm couldn't suppress a pang of powerlessness.
Can you imagine? Every all-out slash lands with solid feedback, yet in the blink of an eye the wound knits itself before your eyes under his boiling vitality and ridiculous recovery.
This isn't battle—it's tossing fuel into a bottomless furnace!
"Shishishi!!"
From across the storm came Luffy's trademark laugh, bright as ever, even louder after the satisfying fight.
This day-long, limit-breaking clash was an irreplaceable treasure to him.
He could "hear" every cell in his body moaning in satisfaction and cracking with growth under the high-stress combat.
Especially Haoshoku; grinding, compressing, and merging with Rayleigh's tempered kingly will made it sharper, deadlier.
And his physique, reforged anew under such pressure.
Rough mental tally:
Hmm… though the gains aren't as extreme as Teacher Kaido's "beat-him-to-death-then-evolve" training,
Rayleigh's "lessons" are fuller, focused on Haki "quality" and battle "technique"—weighty experience!
[Physique: 92.94 → 93.36]
[Haoshoku: 91.36 → 92.08]
Numbers are only abstractions; what matters is the tangible feeling of getting stronger.
Grinning, Luffy looked at Rayleigh with gratitude and undisguised fighting spirit.
'If anyone ever dares call Rayleigh a mediocre teacher again…'
Luffy clenched his still-burning fist, mind set:
'I, Monkey D. Luffy, will be the first to "reason" with my fists!'
This is a top-class sparring partner who perfectly fuses "Haki" and "combat"! The fight is far from over!
—————————
"Uh…?!"
Seeing the pure fighting blaze in Luffy's eyes flare into something almost solid, Rayleigh's mouth twitched.
Is this kid some kind of perpetual-motion machine?
The last dregs of strength in these old bones were squeezed dry in that last burst, yet he looks like he's just getting started!
A long-lost "out of juice" feeling of old age welled up.
He tapped the ground with his scabbard, half-joking, half-serious, sighing in surrender:
"Hey, Luffy… are you set on grinding this old skeleton to dust before you'll quit?"
"Huh?!"
The excitement on Luffy's face froze like a high-speed train slamming the brakes.
He scratched his messy hair, bewildered:
"We're… not fighting anymore?"
His voice brimmed with huge disappointment and disbelief, as if Rayleigh had said the most killjoy thing imaginable.
Seeing that candy-taken-away look, Rayleigh blinked, then a mix of nostalgia, relief, and a spark of defiance rose.
—Memory, comfort, maybe even a stubborn refusal to yield to this pure spirit.
He glanced across the "hell" they'd carved with their own hands, then back at Luffy.
The boy's stamina is a bottomless abyss; his own is nearly spent.
Dragging it out is pointless.
So be it.
Rayley drew a deep breath and slammed his sword fully home into its sheath.
Not surrender, but ritual convergence—compressing every ounce of aura, will, and lifelong insight inward.
He straightened his blood-stained spine; exhaustion remained, yet the majesty of "Dark King" flared anew, gaze like lightning:
"Come, Luffy!"
His voice wasn't loud, but it carried absolute finality, cutting cleanly through the storm's dying howl.
"Forget defense, cast off distractions! Give me everything you've got!"
Feet set, right hand steady on the hilt, he entered perfect stillness.
Not emptiness, but the calm at a storm's eye—ultimate compression before eruption.
"One move settles it!"
Crackle—zzzzzz!!!!
Around Rayleigh, decades-thick Haoshoku—deep as a scarlet sea—surged like an underworld river breaking its banks, pouring into the plain silvery blade.
The sword did not shine; instead it turned darker, swallowing light.
An indescribable silence of annihilation seeped from its edge.
Not the cold of death, but the absolute stillness after an end—an absence where even time halts.
This is the ultimate sword principle distilled by Silvers Rayleigh, the "Dark King," from lifelong experience and kingly will—Nether Truth of the Underworld.
Where the tip pointed, space cracked and caved, revealing deep nothingness behind it.
Echoing from afar—
High above, Luffy threw his head back and laughed; the final shackles seemed to snap apart.
Black thunder brimming with ruinous will and blazing golden fire burning with unyielding spirit erupted from his body like twin rampaging dragons.
In an instant they drove out and devoured every anomaly in the sky, turning the pitch-black heavens into a searing white purgatory of intertwining lightning and flame!
The radiance was so intense the night shone brighter than noon.
Crimson Conqueror's Haki gushed out like a volcanic eruption, spiraling together with his tempered, ink-black Armament Haki, fusing and ascending.
The savagery of thunder, the wildness of flame, the supremacy of Conqueror's Haki… every force became one.
Within that fist, bearer of dreams and promises, they were brutally compressed, merged, evolving into a chaotic yet tyrannical terminal force that surpassed any single attribute.
Across the shattered void the two locked eyes, their gazes smashing through lightning, flame, and nether aura.
No hesitation, no fear.
Both mouths curved into a grin—unbridled, exhilarated, and wild.
In that smile lay a warrior's highest respect for a worthy foe, a silent acknowledgment passed between eras.
"Terminus—"
Two war-cries fused into one, like a declaration or a dirge.
The next instant both figures vanished.
Speed and force broke the limits of perception, turning into two world-ending comets colliding head-on.
One trailing a dark Stygian river that devoured all, the other blazing with fiery lightning destined to incinerate everything in its wake!
With power enough to erase the island beneath them from the map, they crashed together.
"—Yomi-no-Kuni's Slope!!"
Rayleigh swept his sword.
The motion was simple and ancient, as though carving not a slash but a border between life and death.
Where the blade passed, a deep, silent, pitch-black passage linking the "living world" to the "underworld" suddenly opened.
Along its rim, hair-thin spatial cracks spread like a web, exuding an irresistible suction that greedily swallowed and annihilated all matter and energy, even light unable to escape.
"—Tyrant's Requiem of Thunder & Flame!!"
Luffy punched.
Upon his fist the fused chaotic energy finally bared its fangs.
Not mere lightning and fire, but a bizarre existence violently oscillating between "destruction" and "rebirth," exuding an absolute might that ground all things down and suppressed everything.
Where the fist advanced, space itself was forcibly compressed, twisted, then ground into elementary particles by this domineering force!
One path severed all, returning it to the void of the underworld.
One crushed all, a tyrannical finale of lightning and flame.
The clash of termini, in that instant—
detonated!
An instant—
Time lost meaning.
Space lost form.
At the contact point of those ultimate forces from different eras and paths, the first thing to appear was not an explosion but an absolute "nothing."
Light, sound, even the most basic particles of matter were annihilated, forming a miniature "black hole" that kept collapsing inward, devouring everything.
Immediately—
Bzzzzzz—————!!
A primordial roar surpassing all sound burst from that "nothingness."
It was not noise but the terror-filled shriek of space itself on the verge of disintegration.
From the impact center, a sphere of indescribable hue expanded at a speed faster than thought, an apocalyptic ripple of ruin.
Luffy's Iron Fist and Rayleigh's sword-tip pressed dead against each other.
Their forces still madly clashed, annihilated, seeking the slightest chance to overwhelm the other.
Rumble——————!!!!
That was not sound but the ultimate fury of a world buckling under the strain.
The unstable black-red orb pulsing between fist and blade finally passed its critical limit.
First to bear the brunt were the two who had birthed this destruction.
"—!!"
Two silhouettes blasted away from the white core of devastation faster than perception.
Behind them trailed blazing contrails kilometers long from violent friction with the air,
like reverse meteors tearing across a sky only beginning to regain its color.
Splash!!!!!!
One figure traced a long arc and slammed into the churning sea, sending up a gargantuan column of water that blotted the sky.
It was Rayleigh.
Beneath the waves, the former "Pluton" felt every bone as if unjointed, each cell screaming from overload.
Cold brine enveloped him; only the roar of blood and the echo of quivering organs filled his ears.
Extreme exhaustion and the mental shock of impact left his thoughts blank and chaotic; only the hand still clutching his hilt retained a final instinct.
On the other side—
Shhhhk!!!
Air shrieked as it tore.
Luffy stamped on the void, white sonic-boom clouds bursting underfoot as he forcibly halted his backward flight.
Knees slightly bent, he hovered, chest heaving; every breath rasped like a broken bellows, spitting hot white steam.
A shocking sword wound slanted from left shoulder to right flank.
There Rayleigh's absolute sword intent—severing all and returning it to silence—lingered like a stubborn brand, resisting every attempt at closure.
Scalding blood, rich with vitality, poured unchecked from the wound's edge,
falling in ruby droplets that hissed on the seething sea before the waves swallowed them.
The stage of their battle… that once-substantial uninhabited island.
Now it had vanished entirely from these waters.
Where it had stood, only a vast, deep, red-rimmed void remained, still glowing with residual heat and energy turbulence.
Seawater poured madly into the hollow, forming a colossal whirlpool that kept on spinning—a wound the ocean could not quickly heal.
Between sea and sky only the maelstrom's roar, the after-shocks of energy, dripping blood, and two exhausted warriors remained.
