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

Zoro had appeared at the ship's side without anyone noticing. One of his three swords was drawn half an inch from its sheath, and the slash struck through the coating, cutting a deep gash in the giant fish's mouth.

The giant fish, in pain, suddenly turned, its massive tail sweeping past the Sunny and stirring up a surging current of water.

"Hey, you green-haired moss, you almost popped the bubble!" Sanji rushed out of the kitchen and kicked Zoro on the back of the head.

"Shut up, you lecherous cook! If I hadn't intervened, that guy would have swallowed the ship whole!"

Zoro retorted.

"Quiet down, all of you!"

Nami punched them both, and a big bump appeared on each of their heads.

The giant fish had already swum far away, but this incident made the atmosphere on the ship tense.

The creatures in the deep sea are far larger and more dangerous than those on the surface, and even the Straw Hat crew dare not let their guard down.

"That trench ahead is 10,000 meters deep, and Fishman Island is right below it."

Nami pointed ahead and said.

As everyone looked, they saw a huge crack appear in the deep sea, like the open mouth of the earth.

Strange phosphorescence shimmered at the edge of the crack, and some glowing deep-sea creatures swam within it, like stars adorning the abyss.

After entering the trench, the surroundings suddenly became dark.

The Sunny's searchlights could only illuminate a few dozen meters ahead; beyond that, it was complete darkness.

Occasionally, a few bioluminescent fish or jellyfish drift by, bringing a brief moment of light before sinking back into eternal darkness.

Amatsuki was fascinated by the sight. She lay on the gunwale, staring intently at the deep sea outside.

For her, who came from 800 years ago, the sight of the seabed at a depth of 10,000 meters was nothing short of a miracle.

"How beautiful!"

Weiwei also came over at some point and stood side by side with Tianyue Shi. "The deep sea is the cradle of life and the origin of countless legends."

"I never imagined that the seabed would look like this."

"In my time," Tian Yue said softly, her eyes reflecting the glowing sea anemones and drifting jellyfish. "People's understanding of the deep sea was still limited to legends of sea monsters and whirlpools."

Vivi smiled and nodded: "Yes, even now, the deep sea is still an unknown territory for most people, and too many secrets are hidden there."

Her words suddenly stopped, because Merry let out a gasp:

"Yes, there's a big one!"

Big guy?

Everyone immediately looked in the direction Merry pointed, and the beam of the searchlight swept across the darkness, illuminating a huge outline.

It's a really big one!

It was an octopus, but its size was unbelievably enormous.

Its main body is as big as a small mountain, and each of its eight tentacles is over a hundred meters long and covered with suckers, each sucker being large enough to swallow a person.

What's even more terrifying are those eyes, which exude an unparalleled sense of oppression in the deep sea.

"A siren, it's a siren!"

Usopp screamed.

Chopper had already transformed into his beast form, but he was still trembling: "The doctor said there are giant cephalopods in the deep sea, but this is huge!"

"Sanji, can I have some takoyaki?"

Luffy suddenly appeared out of nowhere, his eyes sparkling as he stared at the giant octopus, his mouth practically watering.

Robin, who was behind him, tidied her slightly messy long hair and followed him out, her face still flushed.

It's clear that the two of them had just engaged in some vigorous activity in the room.

"sure,"

Sanji answered instinctively, then suddenly realized, "Wait, are you kidding me? We're underwater!"

Dealing with such a giant monster is difficult even on the surface of the sea, let alone at a depth of 10,000 meters underwater.

The resistance of the water slows down the movement, and once the coating bubble bursts, the Devil Fruit user will lose strength.

Zoro's slash just now almost broke the coating.

The siren in the distance seemed to be startled by the light from the Sunny; its eerie green eyes turned in their direction, and its enormous tentacles slowly moved, reaching towards the Sunny. The surrounding deep-sea currents instantly surged.

The suckers on the tentacles opened and closed, each with a ring of sharp teeth around its edge, making it look particularly terrifying.

"We're doomed! We're doomed!"

Chopper covered his face and peeked through his fingers.

"I never imagined that even sea monsters existed in the deep sea."

Robin pulled out a notebook and pen from somewhere and began to record the physical characteristics of the giant octopus.

Her face was flushed, whether from the exercise she had just done or from the excitement of her discovery, it was hard to tell.

"All personnel, prepare for battle!"

Nami shouted, "Zoro, Sanji, Franky, prepare the coated bubble balls! Everyone else, retreat to the cabin!"

Coated bubble balls are the only way for humans to operate on the seabed. They can generate a small bubble inside the coated bubble, allowing people to briefly enter the seawater to fight.

However, the time should not be too long, otherwise the internal oxygen will be depleted.

While Zoro and Sanji were still frantically preparing the coated bubble ball, Luffy couldn't wait any longer.

"I'll go first."

Luffy stretched his arm backward, penetrating the coated bubble and plunging into the seawater.

Just when everyone thought he would lose his strength due to the seawater, they saw a milky white halo covering Luffy's arm.

When the halo came into contact with the seawater, the seawater was shaken apart, forming a vacuum channel!

"Then, is that the Tremor-Tremor Fruit?" Usopp's eyes widened.

"It can even shake away seawater?"

Franky's jaw nearly dropped. "Super~ That's incredible!"

They knew that Luffy possessed two Devil Fruits, but they didn't expect him to have developed and applied them to this extent.

"What's there to be afraid of in the seawater?"

Luffy grinned, bursting out of the coated bubble, "I'm not afraid of anything now!"

Are you really not afraid of anything?

Robin and Nami exchanged a glance, and a meaningful smile appeared on their lips at the same time.

Weiwei rolled her eyes.

Okay, Luffy is definitely afraid of these two women!

A navigator and an archaeologist working together—even the Emperor of the Sea would have to obey. Playing relay mode? Seriously.

"Wow, these are huge! And the takoyaki are delicious."

Luffy stared at the giant sea monster in front of him, his eyes sparkling.

The siren seemed to sense danger; the tiny human exuded an aura that made it uneasy.

As the overlord of the deep sea, it has not encountered any creature that dares to provoke it for a long time.

The enraged siren brandished its tentacles, and eight enormous tentacles, like a net, enveloped Luffy. Each tentacle carried immense force, stirring up the surrounding seawater into whirlpools.

Luffy neither dodged nor evaded, nor did he use any techniques; he simply covered his entire body with the power of the Tremor-Tremor Fruit.

The moment the tentacle touched Luffy, something strange happened.

Those tentacles, tough enough to crush steel, began to disintegrate the moment they came into contact with the milky white halo, turning into tiny bits of flesh that dissipated into the seawater.

"Waaaaah!!"

The siren let out a painful shriek and quickly retracted its injured tentacles.

Its eyes were filled with terror; this human was far more terrifying than it had imagined.

"Phew, let me give it a try too."

Sanji finally prepared the coated bubble ball, and burst out completely enveloped in a small bubble.

Thinking of the arduous training he had endured over the past two years, being chased by a group of men dressed as women on the island of transvestites, being forced to learn transvestite kung fu, and having to face all sorts of mental pollution every day, Sanji's anger burned fiercely.

Devil's Wind Kick - Finishing Touch Kick!

Sanji's right foot burst into flames that did not go out even in the deep sea.

This is thanks to his mastery of Haki over the past two years, which allows him to use Haki to isolate seawater and maintain the flames.

He kicked one of the siren's tentacles, and flames exploded underwater, forming a huge bubble.

The part of the tentacle that was kicked instantly turned black, and the siren let out another painful howl.

Zoro followed closely behind, his three-sword style ready.

Three-Sword Style: Black Rope: Great Tornado!

Zoro spun in the water, and the water tornado created by his slashing attack swept into the siren's two tentacles, instantly slicing them into countless pieces.

The deep blue blood spread through the seawater, turning the surrounding area into a murky mess.

"That's really strong."

Luffy watched the two of them from the water and grinned.

After two years of training, Zoro and Sanji's strength is now incomparable.

If they can demonstrate such strength in the face of such a behemoth underwater, their strength on land is unimaginable.

In particular, their ability to use techniques in the water to a limited extent demonstrates that their control over Haki has reached a considerably high level.

Takoyaki!

Luffy shot towards the siren's main body like a cannonball, his fist covered with a milky white halo.
