Sailing: His comprehension is against the sky, and he comprehends the Eight Gates at the beginning.

With a roar from Luffy, his massive fist, accelerated by elasticity, shot out and slammed towards Hawkeye.

Like a cannonball leaving the barrel, it roared loudly.

Hawkeye's gaze sharpened, he gripped the knife with both hands, and his figure shifted rapidly at a speed imperceptible to the naked eye.

The surprise attack, launched from a distance of only a few meters, was easily blocked by Hawkeye.

boom!

With a deafening roar, Luffy was forced back by Hawkeye's powerful sword energy.

"Is that all?"

Hawkeye frowned slightly, looking dissatisfied.

Luffy, however, grinned, his expression pleased.

Because in his mind...

"Your comprehension is extraordinary. Through combat experience, your Armament Haki has been strengthened!"

The greater the power of your attack when fighting against such a powerful opponent, the greater the boost you will receive.

He was fighting with Hawkeye as a free sparring partner, so naturally he wanted to make the most of Hawkeye.

If he uses his strongest moves all at once and Hawkeye loses interest in playing with him, then he'll have wasted a chance.

"It's not over yet!"

Luffy responded with a single sentence.

Then he pulled both fists back towards his body at the same time.

He propelled himself into the air by kicking his legs.

Then aim at Eagle Eye.

"Rubber Ape King Crow Cannon!"

Chapter Thirty-Nine: Fourth-Gear Snake-Man Form

Luffy swooped down and unleashed a machine gun version of "King Kong Gun" at Mihawk.

In mid-air, six giant fist phantoms seemed to form continuously, accompanied by booming sounds, relentlessly bombarding Hawkeye.

Eagle Eyes' sharp eyes darted around rapidly, capturing the massive, fast-paced, and densely packed attacks of the Ape King Spear in the air.

The black blade in his hand suddenly increased in speed, creating a series of afterimages.

The powerful clash of Armament Haki, combined with Luffy's torrential attacks, quickly shattered half of the giant ship beneath their feet.

Hawkeye then leaped onto the remaining half of the giant ship.

After unleashing a continuous combo, Luffy's Armament Haki was further enhanced.

Hawkeye couldn't help but sigh and say.

"What a reckless attack method."

Luffy, without stopping, launched another attack.

Maintaining fourth gear already consumes Haki, and he didn't want to waste his Haki on maintaining this state.

"Rubber Rhino Howitzer!"

"Rubber Lion Rocket Launcher!"

"Rubber Great Ape King Gun!"

...

Luffy unleashed a barrage of attacks at Mihawk.

His Armament Haki has been strengthened time and time again.

Hawkeye truly lives up to his reputation as a world-class powerhouse. Luffy almost raised his Armament Haki to another level by learning from him, reaching the top level.

"Rubber Lion King Rocket Launcher!"

Luffy shouted loudly.

Having grown to enormous size, he blew air into his arms again.

Soon, a super-giant form appeared, with two arms comparable to those of a giant ship.

Luffy clenched his hands into tiger claw shapes and compressed them into his body.

With another full-force blast, the enormous roar was comparable to a thunderclap.

With unparalleled momentum, Luffy's massive arms, the size of a giant ship, charged towards Mihawk like a super rocket launcher.

Hawkeye frowned, his face showing seriousness, and his eyes filled with intense confusion.

He had a strange feeling that Luffy's Armament Haki seemed to be getting stronger and stronger as they fought.

Even now, when Luffy uses this move, even he finds it troublesome.

"No wonder Shanks has his eye on this man!"

Hawkeye sighed sincerely, at this moment he had come to acknowledge Luffy.

"Then, I'll show you the world's number one slash!"

As soon as he finished speaking, Hawkeye tightened his grip on the black knife once more.

An astonishing aura erupted from him.

The next moment, green energy emanated from his black blade, spreading outwards like ripples.

He suddenly swung his sword in Luffy's direction, and a slash that seemed to cut through the sea flew towards Luffy.

boom!

The moment the slash collided with Luffy's "Lion King Bazooka".

The heavens and earth roared, and the sea surged.

The powerful energy collision stirred up gusts of wind.

The sea area within a radius of tens of kilometers suddenly became turbulent, with waves crashing one after another.

The enormous floating restaurant, Barradi, looked as if it were about to be overturned and torn to pieces.

Amidst this violent shaking, many people with decent strength gradually awoke.

Zeff, Sanji, Usopp, Krieg, Arkin, and dozens of others, as well as Zoro who had just been stunned by the awakening of Conqueror's Haki, all regained consciousness.

Before they could even wonder why they had suddenly fainted, everyone stared as if they had seen a ghost at the enormous slash that shot into the sky and collided with Luffy, who was as big as a warship.

Krick's eyes widened, his pupils shrank to a point, and his mouth stretched out as if dislocated.

"Ughhhhh... What... what kind of monsters are those?! Can a human do something like that, cleaving the sea in two? And that fist that's bigger than my ship, are they really human?!"

Ah-Fen was covered in cold sweat, her pupils trembled, and her body shook.

"This...this is the true strength of that Hawkeye guy? He really just toyed with sinking 50 of our ships? Is that the true power of the Grand Line? What are we then...?"

Ajin clutched his head in fear, questioning the meaning of life.

Usopp's eyes popped out like springs, his chin dragged on the ground, and his thighs, body, and even his tongue were trembling.

"What a terrifying battle! I feel like I've suddenly contracted a disease that will kill me if I go to the Grand Line."

When Sanji saw this, he was so frightened that he dropped the cigarette butt he had been holding in his mouth when he fainted, and his curled eyebrows twitched up and down.

"Luffy...is he really that strong?! He's actually holding his own against that guy who claims to be the world's strongest swordsman, Hawkeye!!!"

Zoro stared in awe at the sea that had been cleaved open by Mihawk's slash.

"Is there still such a big gap between me and the world's number one?"

The next second, he clenched his fist tightly, his eyes becoming even more determined.

Uta's gaze was fixed on Luffy, and at this moment it was filled with worry.

"Luffy, please don't push yourself!"

She could tell that this wasn't Hawkeye's full strength. When Hawkeye sparred with Shanks, their clashes were so powerful they could split the sky.

But we haven't reached that level yet, yet Luffy seems to have already given it his all.

After a moment of shock, like everyone else, Zhefu was the first to react, shouting in surprise to the chefs who had woken up beside him.

"Raise anchor quickly, or our ship will be destroyed in the blast if we don't get away soon."

Upon hearing this, everyone immediately sprang into action in a panic.

They quickly started the Barratier and drove off into the distance.

Meanwhile, Luffy, after a brief stalemate with Mihawk's slash, suddenly raised his hand and threw his weakened slash into the sky.

"Your comprehension is extraordinary. Through personal combat experience, your Armament Haki has been strengthened."

This time, Luffy's Armament Haki was greatly enhanced, and he could clearly feel that his Armament Haki had improved once again.

But for now, he doesn't plan to continue using this form.

The amount of Armament Haki in his body was almost depleted.

Next, it's time to improve your Observation Haki.

Although Luffy was exhausted, he was in an extremely cheerful mood.

Hawkeye was completely baffled by this scene.

He didn't understand why Luffy was so happy, since Luffy hadn't caused him the slightest harm.

At that moment, Luffy's body shape suddenly began to change rapidly.

At the same time, a large amount of auspicious cloud-like mist, steaming from his sweat, spread out, completely burying his figure.

In an instant, the white "auspicious cloud" transformed into the head of a king serpent, revealing two sharp fangs.

As the "auspicious clouds" dissipated, Luffy's figure became visible.

It is larger than its normal form, but its arms and legs are completely covered in black and red, just like a giant Gear Fourth, and its face still carries a hint of evil.

His hair stood on end like a Saiyan's, swaying and dancing.

"Fourth Gear - Snake Man Form!"

Chapter 40 Who said I have no fighting ability? (Thanks to plmoknij... for the donation, thank you)

Seeing Luffy change his fighting stance, Hawkeye couldn't help but feel a sense of curiosity.

"What's it this time?"

Hawkeye secretly marveled at the convenience of Luffy's Devil Fruit, witnessing Luffy's various bizarre fighting stances and methods.

But what impressed and shocked him the most was Luffy's ever-increasing strength during their battles.

He had never seen anyone possess such talent, getting stronger the more they fought.

Just like Zoro, who had seemed strange to him before, but Zoro's strength was far inferior to his, so this feeling was not obvious.

But when it comes to Luffy, his speed of getting stronger is so obvious that even he can't help but worry if Luffy has enough stamina and enough Haki.

In this battle, Hawkeye is very likely to be the one to lose.

Just as he was thinking this, he suddenly heard Luffy speak.

"Rubber King Cobra!"

The next instant, Luffy's fist retracted into his body like a compressed spring, and then suddenly burst out like a bullet.

What surprised Hawkeye was that this attack method, which was similar to the previous gigantification attack, was surprisingly fast.

Even he could hardly see it with the naked eye.

Hawkeye immediately activated his Observation Haki, predicting Luffy's attack route.

The next moment, he turned and swung his knife, slashing in a certain direction.

However, to his surprise once again, the attack he had anticipated suddenly changed course and turned to another direction.
