One Piece: With Sign-in System-Chapter 166 - : Kaido Transforms into a Dragon!

"Kaido, get out here."

The drunken Kaido, lounging in the palace, opened his eyes slowly upon hearing the words. Swaying unsteadily, he rose to his feet.

"Looks like a little brat with a lot of confidence in his strength has shown up. Such a level of Conqueror's Haki... this guy's got some serious skill."

"King and Jack aren't around, and Queen... that lazy fool must've gone off slacking again."

"Well, there's no helping it..."

He grabbed the spiked kanabo beside him and stepped out of the hall.

Black Maria, one of the Flying Six, had just crawled out of a crater when she spotted Kaido emerging from the palace. She quickly bowed her head. "Master Kaido."

The other Flying Six members turned to look at him as well. Their expressions varied, but deep within their eyes was a shared sense of awe and reverence.

Even though they had just taken a direct blow from a swordsman of the highest caliber, their Ancient Zoan durability and vitality meant they were relatively unscathed. Still, the overwhelming force of that strike and the Conqueror's Haki emanating from above made one thing painfully clear:

The enemy above them was far beyond their level.

"Stand down."

Kaido strode past them, the kanabo in hand.

The group stepped aside.

Kaido walked to the open area ahead and looked up into the sky.

Descending slowly from the heavens was Ron.

"So, you're the one who told me to get out..."

Kaido didn't finish his sentence before his gaze fell on the black-haired youth floating in the air. In Ron's hand was King, bloodied and limp, like a lifeless dog.

Kaido's drunken haze vanished in an instant, his pupils narrowing sharply.

"King?"

The Flying Six also stared at the scene, their eyes wide with disbelief.

"Is that... one of the All-Stars?!"

The pirates of the Beast Pirates on Onigashima looked up at Ron and the defeated King in his grasp, their faces filled with shock.

"No way... the All-Star was beaten? How is that possible?!"

"That's one of the All-Stars! This has to be a joke!"

"Wait a minute, isn't that... the Wanderer, Ron?! What's he doing in Wano?!"

Some among the crowd recognized him.

"What's his plan? Is he declaring war on the Beast Pirates?"

"Him? Alone? Hah! Even jokes have their limits."

Many refused to believe Ron had come to declare war. Even though he had defeated King, he hadn't killed him outright but had instead brought him to Wano. Surely, this was a ploy to negotiate some kind of deal with the Beast Pirates.

"Kaido, you should already know why I'm here."

Ron's calm voice echoed from above.

Kaido, now almost entirely sober, glared at him with a dark expression.

He had recognized Ron as well and understood the implications of his words.

It was about the deal with Doflamingo and Kaido's order for King to attack Ron's Ship, The Traveler.

What Kaido hadn't expected was for King to fall into Ron's hands...

Kaido's cold eyes locked onto Ron, who floated above. "Kid, what are you planning to do?"

"Nothing much," Ron replied flatly.

Gripping King's head tightly, Ron lifted him higher.

Under the disbelieving gazes of Kaido, the Flying Six, and all the Beast Pirates on Onigashima, Ron's right hand clenched with terrifying force.

With a sickening crack, he crushed King's skull like it was a watermelon.

The indomitable vitality of King's Ancient Zoan ability extinguished in an instant.

His headless corpse plummeted to the ground, crashing with a loud boom and leaving a massive crater where it landed.

Every pirate on Onigashima was stunned, their minds reeling from the horrifying sight.

The entirety of Onigashima fell into a dead silence.

In the sky, the black-haired youth casually shook the blood off his hand. His calm voice rang out across the ears of everyone present.

"Kaido, I came all the way to Wano specifically so you could watch your prized All-Star die before your very eyes. So, what do you think? Quite the show, isn't it?"

"You brat! You're courting death!"

A terrifying aura and murderous intent erupted from Kaido's body, shaking all of Onigashima to its core. Fierce winds surged in all directions, the sky darkened rapidly, and countless storm clouds converged and descended.

"If you're so eager to die, then I'll grant your wish."

Kaido's icy voice cut through the roaring winds as his body began to transform. Mist and clouds materialized around him, forming a massive vortex on the ground, flashing with crackling lightning.

Then came a deafening dragon's roar, shaking all of Wano to its foundation. A shockwave of immense power rippled outward, carving massive scars into the sea beyond the island.

A colossal azure dragon burst forth from the vortex, coiling high in the sky. Its cold, piercing eyes locked onto the floating black-haired youth before it.

"Today... you die here."

"That's not so certain," Ron replied with a faint smile, his eyes still closed.

In the next moment, the Conqueror's Haki and murderous intent from both sides erupted, clashing violently in midair.

In an instant, the world quaked.

Below, Onigashima trembled violently, as if it could no longer withstand the sheer force of their aura and would crumble at any moment.

"To think someone could match that bastard father of mine in presence... Who the hell is that guy?"

High above Onigashima's palace, Yamato, with her hands bound by explosive cuffs and her face concealed by a Hannya mask, stared at the sky in utter shock.

Though she despised her wretched father, she couldn't deny his overwhelming strength.

And yet, that boy—who looked even younger than herself—was holding his own against him?!

This had to be a joke!

Kaido, in his Mythical Zoan Azure Dragon form, was over a thousand meters long. Even the slightest movement from him unleashed howling winds. Now that he had set his sights on Ron with murderous intent, his massive tail swung ferociously, causing the very air to explode from its sheer force as it hurtled toward Ron!

Though Yamato was far away, the gale generated by the tail's strike was so intense that she instinctively raised her arm to shield her face. She barely managed to keep her footing, but the force blew her mask clean off, revealing a strikingly beautiful face that bore no resemblance to Kaido's.

"If that bastard father's strike hit directly, it could destroy an entire small island... How's that guy going to block it?"

Yamato, with her white-to-green gradient hair, adorned with hairpins, her tall and slender figure, and ruby-red eyes, looked nervously toward the sky.

At that moment, Ron's figure flickered.

He deftly dodged the dragon's tail strike and appeared high above, gripping his black blade, which was now wreathed in a terrifying sword aura. Without hesitation, he slashed downward.

Yamato saw only a dazzling flash of black light illuminate the sky.

In the next instant—

A massive black slash tore through the heavens, descending toward Kaido's dragon form!

Against the tens-of-thousands-of-meters-long slash that seemed to split the very sky, Kaido's colossal dragon body no longer appeared invincible.

In Yamato's stunned and trembling gaze, Kaido's dragon eyes narrowed.

With both massive claws, he caught the earth-shattering slash head-on.

The immense force of the attack drove Kaido's massive body back hundreds of meters. However, with a roar, he exerted his strength and ripped the condensed slash apart, shattering it completely.

"This level of attack... you thought you could defeat me with just that?"

Kaido's icy dragon eyes fixed on the sword-wielding youth in the distance.

"Don't overestimate yourself!"

Kaido opened his gigantic dragon mouth wide.

ROAR!

Another earth-shaking dragon roar erupted. The sound waves spread out in all directions, shattering the clouds within a hundred-mile radius and splintering the entire sky like broken glass. The ground below cracked under the sheer pressure of the sonic blast.

On the ground, countless Beast Pirates covered their ears, their faces twisted in pain.

"My ears... my eardrums are going to burst..."

"Master Kaido..."

The massive azure dragon twisted its body, riding the swirling clouds as it hurtled directly toward Ron. Its single dragon eye was larger than Ron's entire body.

Ron's black hair whipped wildly in the fierce winds. Even with his eyes closed, he could sense the overwhelming presence, the omnipresent pressure crashing down on him like a tidal wave.

And yet, he remained motionless, unshaken

It was like a natural disaster!

If Kaido wanted, destroying an entire nation would be child's play.

This is the power of an Emperor... Their strength and presence are far beyond even the Admirals.

Ron mused silently to himself.

Yamato, her hair whipping wildly in the gale, stared in disbelief at the black-haired youth high above. He stood calm and composed, his eyes shut, holding his black blade. Her crimson eyes were filled with shock.

"Facing that bastard of a father... He's not showing even a hint of fear or hesitation?"

As Kaido, in his fearsome Azure Dragon form, charged at him with overwhelming force, Ron calmly raised his empty left hand.

Armament Haki: Hardening!

Buzz!

Streams of Armament Haki, shimmering like flowing cherry blossoms, surged into his left arm.

In an instant, his arm turned jet black, gleaming like iron.

Advanced Armament Haki: Stage Three!

This wasn't just the usual hardening or coating. The third stage brought two additional powers:

External Projection: The ability to release Haki outward, concentrating it on the hand or weapon to create a tangible offensive or defensive force. This could generate powerful shockwaves to knock back enemies or form protective barriers capable of deflecting even blade strikes.Internal Destruction: The ability to bypass an opponent's defenses entirely, directly damaging them from within—an essential technique against enemies like Kaido with monstrous durability.

Sun Breathing, Full Concentration!

Ron channeled nearly 3,600 vitality into his left arm.

Essence of Strength: Level Four!

BOOM!

A terrifying wave of heat exploded outward as crimson steam erupted from Ron's body, forming a tornado of energy that howled around him.

"Is he planning to take it head-on?"

Yamato's ruby eyes widened in disbelief as her heart raced.

Under the stunned gazes of Yamato and countless others on Onigashima, the black-haired youth, surrounded by swirling crimson steam, faced Kaido's massive dragon form head-on.

With a fist as black as iron, wrapped in flowing Advanced Armament Haki, Ron swung his left arm forward.

The instant Ron's fist collided with Kaido's dragon head, time seemed to freeze.

For a brief moment, the world stood silent.

Then—

BOOM!

An explosion of unparalleled force shattered the stillness. Two converging shockwaves of immense power erupted outward.

The earth beneath them—Onigashima itself—was instantly torn apart. The ground splintered, debris flew into the air, and a massive crater formed beneath their clash.

Above, the stormy skies, once thick with heavy clouds, now bore a massive hole. For the first time in ages, sunlight broke through the perpetual gloom, illuminating the shattered island below.

Under the stunned and horrified gazes of Yamato, the Flying Six, and the countless Beast Pirates, Kaido's enormous dragon form—once an indomitable symbol of power—was sent flying by a single punch from the black-haired youth, whose size compared to him was like that of an ant to a mountain.

"What?!!"

The Flying Six and the Beast Pirates gaped, their jaws hanging open, eyes bulging as if they might pop out of their sockets.

Before anyone could recover, Ron's crimson-steamed figure vanished in a blur.

Moving at a speed so fast it appeared like teleportation, he reappeared above the retreating Kaido.

Kaido's dragon eyes snapped upward, but before he could react, Ron's fist descended with unrelenting force.

Under Yamato's dazed gaze, Ron's punch connected, sending Kaido's massive dragon form hurtling down from the sky like a meteor.

The impact was earth-shattering.

Kaido's colossal body slammed into the ground, carving a massive scar into Onigashima, leaving a crater so large it seemed as though the island itself might split apart.

This time, no one dared make a sound.
