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

Rumors from within the navy have already spread to the high seas.

Ein never expected to encounter this dangerous figure, whom even Admiral Aokiji couldn't capture, here and in this way.

"Hey, how are you all!"

Even amidst the fierce battle, Luffy managed to find a moment to wave at the oncoming warship.

It's like greeting an old friend.

In Ain's view, this action was nothing short of blatant mockery and provocation!

She was so angry that her face turned pale, and she was about to ask Teacher Zefa for permission to help.

"Ain! You and Binz lead the rest of the crew to hunt down the rest of the Straw Hat Pirates. Leave this ship and Straw Hat Boy to me!" Zephyr ordered without turning his head.

The Straw Hat Pirates' companions are no pushovers either; we must prevent them from interfering with the battle or escaping in the chaos.

"That won't do!" Luffy's smile vanished instantly upon hearing this. "Your opponent is me."

"Rubber-Giant Pistol!"

He took a deep breath, and his arm rapidly expanded as if inflated, instantly transforming into a giant fist as large as a mountain, wrapped in jet-black Armament Haki.

He turned around and was already facing the naval warship that had just approached.

Then it was smashed.

Rumble!

Like a meteorite falling from the sky.

The enormous fist slammed solidly into the side armor of the warship.

The thick armor was as fragile as paper in the face of such absolute power.

The sailors on board swayed and nearly got thrown off.

The massive warship was rocked violently by this terrifying blow, a huge hole was torn in its side, and seawater rushed in.

Although it did not sink immediately, it completely lost its maneuverability and could only carry out emergency repairs on the spot.

Forget about chasing them, they can't even protect themselves!

"You brat, do you think I don't exist?!" Zephyr roared.

Zephyr watched helplessly as Luffy nearly destroyed his flagship with a single punch, and he was furious.

Chapter 287 You're actually a sword master?

Taking advantage of Luffy's recent massive attack and the dissipation of his old strength, it suddenly lunged in front of Luffy, slamming its heavy mechanical arm down on him.

"onslaught!"

boom!

This attack landed squarely on Luffy.

He managed to throw a punch, but was still slammed downwards, crashing through several layers of cabin walls before finally coming to a stop amidst the chaotic ruins.

However, the next second, Luffy nonchalantly peeled off the wooden planks covering him, stood up, and dusted himself off. "Ouch, that really hurt. But it seems like I've gained something."

Zephyr did not answer. His face was gloomy as he looked at the spot on his mechanical arm where Luffy's fist had just collided with his.

There was a clearly visible fist print there!

This thing is made of some of the world's strongest alloys, and its internal skeleton is mixed with high-purity seastone. Its hardness far exceeds that of ordinary steel, and it is difficult to damage even with the full force of a naval vice admiral.

To leave such clear marks on this, was it a hasty counterattack...?

"Didn't you say you couldn't handle entanglement?" Zefa asked in a deep voice.

That punch, though terrifying in power, still felt like pure Armament Haki and physical strength.

It wasn't Conqueror's Haki that was emanating from it.

"I really don't know how yet." Luffy cracked his neck, making a snapping sound. "But when I fought with that old man before, he hit me pretty hard a few times, and I vaguely figured out a bit of the knack, but I just can't get the hang of it."

My encounter just now gave me some insights, and now I'd like to ask you, sir, to help me verify them. I think the relationship between Overlord's Entanglement and ordinary Armament Haki Entanglement is quite significant.

He made his purpose clear from the start.

"Using me as a whetstone?"

Zephyr was taken aback at first, then laughed in anger, "Fine! Very well! Kid, since you're so confident in yourself, then come on! Using me as a whetstone will consume a lot of your Haki. Let's see if your Haki runs out first, or if I'll smash you into Impel Down first!"

Although he was furious, seeing such a talented young man, his instinct as the head instructor made him want to give him some pointers.

Moreover, Luffy's bold, unrestrained, and straightforward temperament, similar to Garp's, easily inspires admiration.

Zephyr himself didn't know whether it was right or wrong to let Luffy test the prototype of Binding on him at this moment.

But at this point in the battle, we must give it our all!

He was actually more interested in knowing who Luffy had fought.

Those who possess Conqueror's Haki are already extremely rare, and those who can effectively use it in actual combat are even fewer.

At this moment, Luffy slightly lowered his body, like a cheetah poised to pounce, and charged towards Zephyr once again.

His fist was covered in solid Armament Haki, but beneath that darkness, a faint, almost imperceptible, dark red light seemed to occasionally flash.

The fist blurred into a blur and swung out again.

Boom! !

The fists struck Zephyr's raised mechanical arm like a storm, producing a dull thud.

Under such dense and heavy impacts, the hard alloy shell began to show slight deformation and dents.

"His personality is exactly the same as Garp's,"

Zefa felt the intense vibrations from the mechanical arm and the strange fluctuations that seemed to penetrate his defenses. With a hint of reprimand, he spoke:

"You really are a complete brute. With your stamina and domineering spirit being squandered so recklessly, even if you are exceptionally talented, you won't last long! The one who will have the last laugh will definitely be this old man who can fight for longer!"

Who knows!

Luffy grinned, his offensive undiminished. "How will I know where my limits are if I don't try!"

Zephyr was annoyed by Luffy's almost shameless answer. He seized the moment when Luffy was exhausted and needed to catch his breath after a fierce attack, and his left hand swiftly reached out like an iron clamp, accurately grabbing Luffy's wrist after he had just finished swinging!

At the same time, his eyes widened, and he let out a thunderous roar. With his waist and abdomen exerting force, he used his absolute strength, which far exceeded Luffy's, to lift Luffy's rubber body up and slam it hard onto the already damaged deck.

"Dominance and stamina aren't things you can get by just being reckless. Wake up!"

BOOM!

With a loud crash, Luffy was slammed deep into the deck, instantly creating a human-shaped dent, with wood chips and debris flying everywhere.

Almost simultaneously with the impact, Zephyr relentlessly tugged at the mechanical arm, aiming the cannon at the center of the dent at Luffy once again. The gun barrel and energy conduit inside the mechanical arm hummed and began to spin rapidly to preheat!

"It's over, Straw Hat Boy!"

"Rubber, Spinning Sword Dance!!"

A low shout came from the depression.

Immediately afterwards, a jet-black sword blade, like a dragon emerging from the abyss, suddenly slashed upwards.

The sword's edge was wreathed in Armament Haki, and it also carried a faint hint of sharpness that could cut through anything.

Click!

scoff!

The energy transmission pipe and main transmission structure connected to the robotic arm were severed as easily as a hot knife through butter in the face of this sudden, dark blade.

Immediately following, as if triggering a chain reaction of collapse, the complex mechanical arm connected to the right shoulder disintegrated from its internal parts under the vibration of the sword energy, turning into countless parts and fragments that crashed to the ground, revealing Zephyr's slightly slender metal prosthetic arm.

The jet-black sword, undeterred by its momentum, with a sharpness capable of slicing through anything, cleaved straight for Zefa's face with a piercing whistling sound.

Zefa's pupils suddenly contracted to the size of pinpoints; this unexpected turn of events was completely beyond his expectations.

At the critical moment, almost relying on his combat instincts honed over decades, he instantly unleashed his Armament Haki to its fullest extent with his intact left hand, turning his entire forearm into black steel. Instinctively, he met the incoming black blade with a punch!

boom!

Fist and knife clashed, producing a deafening clang of metal striking metal.

A sharp and unparalleled sword aura collided fiercely with an incomparably powerful fist force.

Zefa's body jolted violently, and he uncontrollably staggered back several steps, each step leaving deep footprints on the deck, before he finally managed to regain his balance.

He stared in disbelief at the scattered mechanical arm parts, then looked at Luffy leaping out of the crater, holding a powerful, jet-black longsword.

"You're actually a swordsman?!" Zephyr exclaimed in shock.

Garp's grandson, that old man who only knows how to fight recklessly with his fists, actually has a swordsman grandson? And he's grown into a swordsman who can cut off Garp's specially made mechanical arm?!

The shock of this incident was so great that even the battle-hardened former general Zephyr was unable to fully recover for a while!

Chapter 288 One monster like Garp is enough

Uncle, times have changed.

Luffy gripped the sword in one hand, casually twirled it, and slung the Supreme Grade Sword named Demonic Will over his shoulder, flashing a bright smile at Zephyr:

"I'd say I'm half a swordsman! As for attack methods, the more the better, it's always good to be prepared!"

From the very beginning of the battle, he had his sights set on Zephyr's mechanical arm.

It can fire Seastone bullets and energy cannons.

This thing is too dangerous. If he gets caught or hit by a Seastone bullet, he will lose his strength instantly.

Therefore, prioritizing the elimination of this biggest threat is the best course of action.
