Luffy, how can you become the Pirate King if you don't work hard!

"Thunderous Eight Trigrams!"

Kaido's signature loud laughter echoed from high above, and the massive blue dragon swooped down from the clouds, taking Big Mom's place.

As the dragon swooped down, it began to shrink and deform rapidly. Its blue scales faded, its horns contracted, and it transformed back into its imposing human form.

"Ape God Spear!"

Luffy charged forward and blocked the attack with a simple straight punch.

"Straw Hat, throw away that messy weapon. You're better off fighting bare-handed!"

Kaido laughed and said, "You have the shadow of that old man Garp in you. Now your fists are as powerful as that iron fist."

It even hurts more!

"Indeed, since you're so eager to experience the taste of Iron Fist, then I'll grant your wish."

Luffy laughed loudly, flipped his wrist, and the black sword spun in his hand before he tossed it high into the sky.

In terms of swordsmanship, he is certainly no match for a great swordsman like Hawkeye; he's purely addicted to swordsmanship. However, he also has his own advantages.

However, since Kaido has said so, it's time to unleash our full power to resolve this battle!

The moment the words fell, Luffy's body shot out like a cannonball. Kaido could only see a white afterimage. Then, he subconsciously swung his spiked club, Eighth Order, and purple lightning exploded on the club, smashing it hard towards the white afterimage.

Luffy's body twisted at an odd angle in mid-air, the spiked club grazing his head. Then, Luffy's right foot slammed down, his foot covered in Armament Haki directly stepping on the spiked club, forcefully stomping down Kaido's attack.

"Boom!"

Kaido's pupils contracted sharply, and Luffy's next attack was already upon him.

He clenched his right fist, and Armament Haki surged wildly into it. Black and red Conqueror's Haki exploded on his fist, which he then swung at Kaido's face.

"A general amnesty!"

A punch landed squarely on Kaido's left cheek. The Conqueror's Haki on the fist exploded the moment of contact, and the black and red lightning surged wildly into Kaido's body. The shockwave formed by Armament Haki exploded on Kaido's cheek.

boom!

With a dull thud, Kaido's head was knocked to one side, and blood splattered from the corner of his mouth, drawing a bloody line in the air.

His body slid backward dozens of meters under the impact of this force, and the air beneath his feet made a series of popping sounds.

"So, are you satisfied?!"

"Kid, that's more like it!"

Kaido roared, his legs suddenly exerted force, and he leaped into the air, instantly jumping hundreds of meters into the sky.

He gripped the Eight Precepts with both hands, and purple lightning swirled wildly on his spiked club. But just as he leaped into the air, a white figure appeared strangely above him.

"too slow!"

Luffy laughed loudly, raising his right leg high. Steam billowed from his leg, and his entire right leg swelled several times in an instant. Armament Haki completely covered his leg, forming a black hardening like steel.

"Rubber Rubber - Giant Battle Axe!"

The giant's leg fell from Kaido's head, striking his back with terrifying force, like a mountain crashing down.

boom!

Kaido's body plummeted from the sky like a meteorite, crashing straight down onto Onigashima below.

A huge crack spread outwards from where Kaido crashed, dust billowed into the sky, and rubble rained down.

"Close combat is my specialty!"

"Well?"

Just then, a strange sound came from afar.

Luffy turned his head and saw a huge soul shockwave rising from the ruins of Onigashima, hurtling towards him.

The sound struck his very soul, and blood spilled from Luffy's mouth. His recovery speed could not keep up with the speed of his injury. Once this threshold was broken, his fighting power would drop rapidly.

Big Mom and Kaido are like that, and Luffy has only just reached this state, which is already truly abnormal.

"Well, well, well, we're finally seeing results!"

Big Mom crawled out of the rubble, her body covered in wounds, her clothes tattered, and her hair disheveled and hanging over her shoulders.

"You're like a demon crawled out of hell."

Luffy wiped away the blood. "Looks like he's not going to make it."

"That's not necessarily true!"

Big Mom roared, and a soul shockwave expanded and deformed in the air, turning into a giant demonic face that opened its blood-red maw and devoured Luffy.

Luffy's eyes narrowed, and he moved sideways at an extremely fast speed, the soul shockwave grazing past his body.

But that strange soul power still affected his consciousness, slowing his movements slightly for a moment.

In that instant of hesitation, Big Mom had already rushed in front of him.

The Napoleon sword in her hand was burning with intense flames as she swung it down towards Luffy's head.

"Go to hell!"

Luffy's body suddenly sank downwards, and Napoleon slashed past his hair.

Immediately afterwards, his right fist came up from below, like a rising dragon, and slammed towards Big Mom's chin.

"Rubber Rubber - Rising Dragon Fist!"

boom!

A fist covered in Armament Haki slammed solidly into Big Mom's chin, the immense force sending her head flying high into the air, blood mixed with saliva spurting from her mouth.

But Big Mom seemed to feel no pain at all in this state. The moment her head was knocked up, she spread her left hand, her Armament Haki gathered at her fingertips, and fiercely grabbed at Luffy's chest.

Luffy leaned back, dodging Big Mom's grab. The madwoman's attack followed immediately; her knee shot up and slammed into Luffy's stomach.

Luffy crossed his hands and pressed down, blocking the knee strike. The collision of the two forces once again generated a violent shockwave.

After a brief exchange of blows, Luffy suddenly pulled his body backward to create distance.

He looked down at his palm, where the tremor from the collision with Big Mom still lingered.

The force has subsided.

After withstanding several attacks from the Heavenly King, Big Mom's stamina was almost depleted.

Correspondingly, his condition continued to decline.

"It's time for the final battle!"

His body began to change; his expanded form began to compress, and the white steam stopped spreading outward and began to condense inward.

Concentration is the essence.

Kaido flew out of the crater in the ground, his body covered in dust and pebbles, but the fighting spirit in his vertical pupils remained undiminished.

He saw the change in Luffy's physique and instantly understood what Luffy was doing.

"Are you going to fight to the death, Straw Hat Boy?!"

Kaido roared, and his body began to swell and deform again. Blue scales reappeared, dragon horns grew from his forehead, and his body quickly elongated, transforming back into that enormous blue dragon.

"This should be the last one!"

Kaido laughed heartily.

He was once a young soldier in the Battle of Ward, betrayed by his country and the world.

He struggled to survive in that cruel world, and climbed to where he is today step by step through his own efforts.

He was once an apprentice crew member of the Rocks Pirates, fought against Roger and Garp in God Valley, was captured by the Navy countless times, and was sentenced to death countless times.

But none of them were able to kill him.

He became one of the Four Emperors, occupied Wano Country, and established his own power.

He had been waiting, waiting for someone who could truly fight him, waiting for someone who could break the deadlock in this world.

And now, this person has finally appeared.

Chapter 600 This era is called Luffy!

"Oro ro ro ro, Straw Hat Luffy!"

Kaido's dragon body circled once in the air, and the fiery clouds around him began to surge violently.

The sky above the entire Onigashima was dyed crimson by fiery clouds, as if the end of the world had arrived.

The intense heat caused the seawater below to boil, and steam rose from the surface, forming a white mist.

"Fire Dragon Torch!"

Kaido's dragon body was completely engulfed in flames, which were so hot that they turned Kaido into a real fire dragon.

Everything will be poured into this one strike.

There is no retreat!

"Hey hey hey, don't forget me, Kaido!"

Just then, Big Mom's voice came from the side.

Big Mom rose from the ruins, and her body began to change.

Her Devil Fruit powers were completely drained, and her soul transformed into tangible energy that surged from her body, forming a strange soul armor around her.

The Homies were all devoured, even those Homies in the myriad kingdoms.

"Soul-Soul Fruit - Forbidden Technique - Soul Devouring!"

Big Mom's hair stood on end, and her eyes turned pure black, with no whites visible.

"I've never seen this move before. Is it newly developed?"

Luffy saw the soul power in front of Big Mom condense into a giant skull-shaped energy body in the air.
