Three Types of Haki, Ten Seconds of Invincibility

Fifth Gear?

Not to mention Teach on the other side, even Roman, who was possessed by Nami, and the rest of the Straw Hat crew all turned their heads to look! After all, Luffy's strength increases dramatically every time he 'upgrades,' so this time:

How much improvement will there be?

Roman was also looking forward to it.

"While Fourth Gear possesses immense strength and size, it doesn't hold an advantage when facing powerful opponents..."

As Luffy injected air into his bones to transform into Fourth Gear Bouncer, he gained immense strength and physique. However, in a battle between experts, it's all nonsense if you can't hit your opponent! For example, when he faced Katakuri.

And:

"The larger the size, the more Armament Haki is needed for defense, and the more openings will appear."

Call--

An invisible Haki erupted from Luffy! But after only half a meter from his body, it was immediately controlled by Luffy's powerful will and then abruptly pulled back:

"Double Haki compression?!"

The Roman attached to Nami were dumbfounded; this was exactly the technique they had learned after enduring a year of beatings from Garp...

"Hehehe~~ I've seen Roman use it so many times, I've learned it without even realizing it."

Faced with Luffy's playful explanation, Nami (Roman) nodded expressionlessly, inwardly speechless. "You'll get it after 'watching it a few times'? Are you some jealous neighbor?! I've taken a beating this whole year..."

No, think about it carefully, how many years did Luffy get beaten up by his grandfather when he was a child? — Thinking about it this way makes it much more balanced.

Crackle, crackle!

Luffy's Armament Haki suddenly contracted, compressing his towering Gear Fourth Gear Boundman form back to its normal size! He looked like a 'Snake Man,' but at that time Luffy wasn't Conqueror's Haki Entwine, and:

The so-called Snake Man Mode is actually the prototype of the Fifth Gear.

Click,

"Careful,"

"Tsk, isn't this exactly the same as 'Super Saiyan'?"

As Luffy stood up, black patterns wrapped around his body, extending to his neck, making him appear mysterious and majestic! Even more terrifying were the crackling black Inazuma erupting from his body, resembling Super Saiyan 3 power! This caused Roman, who was clinging to Nami beside him, to narrow his eyes.

"By releasing Armament Haki externally and compressing it back in, while maintaining the strength and physique of Fourth Gear, the speed is greatly increased. Moreover, the defensive armor formed by the dual Haki can isolate all Devil Fruit abilities."

"At the same time, Conqueror's Haki coating his body, granting him a terrifying attack capable of tearing through space..."

Add to that Luffy's Observation Haki that allows him to 'Future Sight,' and it's practically an epitaph + a space-bombing masterpiece + a platinum panel + Twenty Century Boys...

Invincible, truly invincible!

"Ten seconds,"

Blackbeard was taken aback by Luffy's words after he transformed.

"Teach, I can only maintain this state for ten seconds, so:"

I'll take care of you in ten seconds!

?!

"Back--"

The moment Lia uttered her words of warning on his shoulder, an unimaginable force surged from behind him! The next second:

What am I doing...?

Teach, whose back had gone numb, blinked and realized he was 'floating' in mid-air! Turning his head slightly, he saw a palm-sized island below, and beside him, a swarm of warships scattered like ants across the sea...

Warships? Islands? Could it be—

Brush,

A figure enveloped in black Inazuma suddenly appeared beside Blackbeard, and before he could react, a jet-black fist slammed into his muscular chest!

Click,

Amidst the crisp sound of ribs breaking, there was Teach cloud of dark smoke and Armament Haki instantly blasted Teach to shreds. The Two-Color Haki, one bright and one dark, broke through Teach's defenses and penetrated his entire body, even reaching deep into his bones and internal organs!

The next moment, Conqueror's Haki that tore through space and Armament Haki penetrated every nook and cranny erupted simultaneously, causing Teach to see stars, feel his blood surging in his chest, experience excruciating pain in his internal organs, and hear every bone in his body cracking and splintering like popping beans as they violently displaced and rubbed against each other. Accompanied by the faint sound of bones breaking, every muscle was twitching uncontrollably, spasming and convulsing, as if every part of his body was being pulled back and forth by different forces, repeatedly shaken and jolted.

I was attacked by the Straw Hat Kid?!

Puff,

Only after a moment of stunned Teach did Teach realize what had happened to him, and a mouthful of blood gushed out! His body was still frozen in place Luffy Teach's Haki, and even as he desperately tried to move, he couldn't even move a finger—

Click!

In an instant, Luffy's attack came again, instantly knocking the rapidly falling Teach sideways in mid-air!

"This is really..."

Watching Blackbeard being thoroughly 'beaten' in mid-air, and Luffy so fast he was reduced to a dense streak of black Inazuma cutting through the sky, Roman couldn't help but stroke his chin. The smoothness of his skin brought him back to his senses. —This is Nami's body.

"Isn't that interesting?"

On the other side, Zoro, leaning on his sword, looked quite excited. For him, as long as there were stronger opponents to surpass, he had the motivation to continue becoming stronger. Seeing Luffy's invincible Gear Fifth Gear unleashed, the Straw Hat crew breathed a sigh of relief. However, Teach, their target, was...

In an instant, the situation did indeed 'reverse'! Unfortunately, it was completely contrary to his plan; the constant, excruciating pain throughout his body clearly demonstrated the terror of the opponent's attack! Even his Armament Haki and Dark-Dark Fruit ability couldn't withstand it. If this continued:

Teach didn't know how many more blows he could take! One punch, two punches, or three punches?... But he knew very well that if he didn't make a change, he would be beaten into a hideous corpse with shattered bones, twisted muscles, and crooked eyes by the Straw Hat Kid, just like a puppet!

Impossible! I'm going to be the King of the Pirates! I've been working towards this day for decades!

Is it possible that 'we' are truly powerless against this Straw Hat Kid...?

In an instant, Teach felt utter despair. But Teach, who was beating him like a punching bag with a cloud of black Inazuma, wasn't having an easy Luffy either: using Future Sight to control the battle, releasing Armament Haki to block the Dark-Dark Fruit's power, and using Conqueror's Haki coating break through his defenses...

This is why Teach is Luffy tossing Teach around! Not one of them can be missing, yet Teach's incredibly strong body, honed through countless trials, continues to persevere. Even as Luffy beats him until he's covered in blood and looks utterly miserable, he grits his teeth and endures it all! It's a battle of wills:

"Down you go!"

Crackling

Suddenly appearing above Teach Luffy unleashed a powerful punch! In that instant, his rubber body, enveloped in the Three Types of Haki, vibrated at a high frequency, causing ripples to appear in the 'space' in front of his fist!

Faced with Luffy's punch, all the abilities like the 'Door-Door Fruit,' 'Swap-Swap Fruit,' and 'Castle-Castle Fruit' would be rendered useless! Because his punch is powerful enough to interfere with the operation of a space.

This punch is sure to hit!

As Luffy's Luffy landed, the space around Teach was completely locked! Not to mention that he was numb and unable to control his body, even if he were in his best condition, he would have no chance to dodge Luffy's punch.

It's over!

Under Luffy's fist, only despair remained in Teach's eyes! This level of attack...

"Let me do it,"

The whisper in his ear had barely faded when a figure in a dress detached from Blackbeard's body and suddenly lunged upwards to meet Luffy's fist.

?!

"Get out of the way—"

Before Luffy could stop in time, Annie, surrounded by four 'Homies' —one of lightning, one of fire, one of ice, and one of earth—stood in front of Blackbeard. Facing Luffy's Heavenly Annihilation punch, the long-haired girl calmly pressed the 'Homies' created by the souls of the four top experts into her palm.

Pirates are all about winners taking all, and losers losing everything.

There's nothing to complain about:

"Elemental Annihilation,"

As the girl murmured to herself, the four elements suddenly merged together, transforming into a pitch-black 'origin'! It was the final, irreconcilable fusion of conflicting elemental forces under their master's command!

"Bring it on,"

As the girl with long, straight black hair gently raised the 'point' in her hand to Luffy Luffy's unparalleled punch, the terrifying power of both sides spread out layer upon layer, forming a huge sphere composed of countless layers of space twisted and superimposed together. Each layer of space fluctuation had the power to tear apart diamonds, or even any metal in the world.

However, this was merely the aftermath of their clash of ultimate techniques...

"Not good!"

Roman, Zoro, Katakuri, whose strength had reached a certain level, along with Momousagi and Chaton from the outer sea, all felt a sudden sense of alarm, sensing an immense and terrifying power that could almost destroy the world about to erupt.

"Awakening, Shielding, Blazing Sky Seven-Ring!"

As Roman raised his hands, a large amount of paper vanished into thin air, forming a seven-layered shield that blocked the sky! It was far more powerful than the legendary Shield of Ajax from the Trojan War, and Zoro instantly unleashed three sword strikes, not even having time to utter a poem:

"Three Thousand Great Worlds!"

A gigantic Flying Slash that tore through the sky, the sea, and the islands soared into the sky!

Meanwhile, Katakuri waved his hands, and the ground suddenly turned into rolling mochi, protecting the Charlotte Family like waves. At the same time, his Armament Haki covered the mochi fortress, turning it pitch black.

"Awakening: Castle Rice Cake!"

Boom--

A true cataclysmic event, the earth shook violently!

In mid-air, a jet-black sphere of light rapidly expanded from small to large, growing into a massive 'solar eclipse' hundreds of meters in diameter. It suddenly contracted before bursting open again with unbridled force, radiating enormous shockwaves and heat sources in all directions! A mushroom-shaped cloud wrapped in black Inazuma shot straight into the sky thousands of meters high, causing all the powerful beings in the New World to turn their heads sharply!

Even if they can't see it, within the Observation Haki:

"How scary~~"

"What kind of powerful figures are fighting?!"

"Such terrifying power... even the Four Emperors..."

Unless Whitebeard and Roger are reborn, this world shouldn't have such a terrifying clash—

Because the attack was launched in mid-air in all directions, the surface of the Whole Cake Chateau below remained largely intact. However, the immense pressure caused the entire island to tremble violently as if it had been stomped on by a god from above, and then suddenly sank dozens or even hundreds of meters downwards!

This location is much lower than sea level. Originally, Whole Cake Chateau should have been completely submerged in the sea. However, the infinite energy and heat that burst out in all directions either evaporated the seawater within a radius of tens of miles or pushed it away in all directions, creating a 'basin' in the sea.

It might take several more minutes for the massive tsunami, surging in from all directions, to completely submerge this area. Meanwhile, the residual shockwaves of this attack are still spreading over a hundred miles away, causing countless natural disasters!

It's fair to say that this collision has completely destroyed Whole Cake Island.

If we have to say something, the fact that Whole Cake Island was nearly empty due to the Blackbeard Pirates' rampage is perhaps a stroke of luck amidst misfortune.

PS1: Law could slice through an island with a single strike when he was on Ice-Fire Island, so it's reasonable for Luffy to sink an island with a single punch now (even if it's not entirely justified, he still feels justified). Ahem, okay, the main point is that Blackbeard, as the final boss of the Straw Hat crew's 'pirate' career, should at least be on par with a young Whitebeard or Roger.

PS2: 'Twenty Century Boys' is the Stand of Magette Magette in JoJo's Bizarre Adventure Part 7. He's immune to all damage as long as he remains still. The main characters then tied him up and threw him into the river. If he deactivates his Stand, he'll drown, but as long as he doesn't deactivate it, he won't drown; he'll even starve or die of thirst. Therefore, along with Kato and Kars, he gave up on thinking...
