One Piece: Nobody knows Devil Fruits better than me.

Chapter 42 Coach, I want to learn this!

"Um!?"

At this moment, Zephyr, who was observing Roy's situation from inside the coating pipe, had already noticed something was wrong.

At this moment, Royna's body, which had been slightly bent due to the pressure from the water, began to slowly calm down.

then
To Zefa's astonishment, Roy's figure gradually straightened up.

"Clang!" "Clang!"

From within his bones, sounds like the crackling of metal emanated.

then
Zefa then saw that Roy had actually raised his hand slightly and beckoned to him.

Zephyr, of course, knew the force required to perform this simple action 5000 meters below the surface of the ocean.

"Roy, your body..."

Even this experienced former general couldn't help but look at Roy at this moment, his eyes flashing with a sharp light.

His voice was filled with unconcealed horror.

Recently, he has been studying Roy's training report and believes that he knows Roy's physical condition even better than Roy himself.

But without a doubt, at this moment, Roy once again shattered his expectations.

"Ah."

At that moment, Roy nodded without hesitation: "I think I've gotten used to it, Professor Zephyr."

One has two.

In the last instance, he had already planted the seed of 'Roy Amos is a monstrous genius with exceptional talent' in Zeffa.

So now, he naturally doesn't need to find any extra reasons—that would only make him seem more suspicious.

And this is indeed the case.

"Have you adapted?"

At this moment, Zephyr's expression turned noticeably serious after hearing Roy's words.

But he still had no doubt about what Roy said—Roy was in the sea right now, so of course he didn't think Roy was a power user.

so.
"Such a physique is simply unheard of!"

Zefa shook his head with a sigh.

“Professor Zephyr, I don’t like hearing you say that.”

Upon hearing this, Roy retorted righteously and sternly.

"What do you mean by physique? My becoming stronger isn't entirely due to my physique; it also includes my own real hard work, okay?"

"effort."

Upon hearing this, Zefa rolled his eyes at Roy.

Although he's been busy lately, he knows what Roy's situation is like at the base—he spends his days lazily drinking cola and has absolutely no interest in working hard.

However, he didn't say much, only saying, "Are you sure you've adapted? Don't push yourself—you must tell me if you feel any discomfort, whether it's in your bones, muscles, or internal organs."

He would rather slow down the training pace than let Roy, the only current successor, get injured.

"of course."

Roy nodded and smiled. "I'm sure they're all healthy."

And it was precisely at the moment he said this that...

If Zephyr could see through his body, he would surely discover it.
Whether it's the bones and internal organs inside Roy's body, or his incredibly powerful muscles enhanced by the 'Wind God Wyvern', 'Great Buddha Fruit', and 'Strong Fruit'.

At this moment, everything was covered with a metallic luster like steel.

But in Roy's eyes, the truth of everything was clearly displayed on the screen of light.

[Fruit Slot 4: Void → Quick Cut Fruit LV3]

【Quick-Cut Fruit】

[Devil Fruit Ability - Can transform any part of the body into blades and harden them]

[Effects at Each Level]

[LV1: Gain a minor fruit effect, slightly enhancing body defense and toughness]

[LV2: Gain some fruit effects, can transform the body into a blade and enhance defense, with the hardness increased to 'Rough Iron', requires 6000 million/2000 million to permanently/temporarily unlock]

[LV3: Gain all Devil Fruit effects, transform your body into a blade and enhance your defense, increasing its hardness to 'steel'. Requires 3 million/1 million Berries to permanently/temporarily unlock.]

[LV4: Deep fruit development allows the blade formed from the body to rotate and deform, and the body's hardness is enhanced to 'high-strength steel,' greatly increasing the body's hardness and sharpness. Requires 10 billion/3 million Berries to permanently/temporarily unlock]

[LV5: Fruit Awakening - All-Encompassing Slash, can control the entire environment around the body to turn into blades to slash enemies, sharp enough to cut through mountains, and the hardness of the body is increased to 'alloy', requires 60 billion Berries/20 billion Berries to permanently/temporarily unlock]

That's right.

At this moment, Roy had already loaded the 'Quick Cut Fruit' into his fourth fruit slot.

The enhancement of this fruit was something Roy had already planned long ago.

"While the Quick Cut Fruit cannot be considered a very powerful Paramecia-type Devil Fruit, in fact, in terms of the diversity of its abilities, it is still inferior to the Weapon Fruit."

"But its ability to enhance the body's hardness is extremely practical, and as long as the body is not turned into a sharp blade, it will almost never be discovered."

Roy was well aware of the fruit's advantages—it was practical and inexpensive, truly 'good value for money'.

According to Roy's plan, his next clone will use this fruit.

However, Roy didn't expect that—before his next clone even had a chance to use this thing, he would use it here first.

"Um"

After confirming that Roy seemed to have fully adapted to the water pressure at a depth of 5000 meters,

Zefa sighed inwardly again, and then no longer hesitated.

"Since you've already adapted..."

Then, Armament Haki began to swirl around Zephyr's body.

The dark, domineering aura completely enveloped Zephyr's body, making him appear as if he had merged with the dark sea.

Then Zefa leaped into the deep sea, passing directly through the coated pipe.

"Follow me."

Zefa waved and then swam with Roy into the deeper waters.

There is only tranquility in the deep sea.

Even with the Quick-Cut Fruit attached, which gave him enough defense to withstand the water pressure, Roy still found it somewhat difficult to navigate in the darkness.

“So strong!”

Looking at Zephyr, who seemed to be effortlessly enveloped in Armament Haki, Roy couldn't help but sigh inwardly once again.

But it was precisely at this moment
"Um!?"

Roy's heart skipped a beat. Because at this moment, he could clearly perceive the changes in his surroundings.

"Has the resistance of the seawater increased?"

"No, that's not right."

He murmured to himself, but quickly came to the correct conclusion.

"It's the seawater ahead—something's wrong with it!"

As he reached this conclusion, he also heard Zephyr's voice.

"coming."

coming?

What's coming?
A sense of doubt instinctively arose in Roy's mind.

But the next second, the sight before his eyes made his pupils shrink abruptly.

At this moment, in the already deep and dark ocean...

Then, even larger, dark figures appeared.

Those figures were so enormous that they could almost stretch across the entire deep sea.

They have long, slender bodies, and appear to be enormous 'giant snakes'.

Each one is incredibly long and seemingly endless, and even their thickness is as large as a mountain.

On their 'body', Roy could see specks of light, like scales.

It was with that sliver of light that Roy was able to see what those 'giant snakes' were.

They are ocean currents!

Those 'scales' are bioluminescent organisms and mineral fragments from the deep sea, while the enormous body is the trace of ocean currents.

So, Roy found out what this thing was.

"The Marin Mega Circulation?"

Just as mentioned before—Roy is currently located in the deep sea beneath the island of Marineford.

As is widely known, Marineford, Enies Lobby, and Impel Down form a 'triangular structure' in the sea, guarded by three Gates of Justice.

The three gates of justice remain closed year-round, forming a place known as the 'Sea of ​​Justice'.

Within this unique sea area lies the largest known ocean current in the Grand Line.

Its name is 'Marin Mega Circulation'.

Its existence in this sea area prevents almost all ships, except those of the World Government and the Navy, from passing through it, leaving them only able to circle around it.

"That's right!"

At this moment, Ze Law spoke in a deep voice.

"It is the 'Black Serpent'—it exists on the seabed of Marineford, part of the 'Marin Gyre'."

"Old man."

Roy was having trouble even speaking at this point.

"You're not going to tell me that this so-called 'formal training' is what it is."

"That's right—fighting the pressure of the deep sea is just the beginning. What you really have to deal with are these 'black snakes,' and then defeat them!"

Zefa's words were clear and powerful.

Roy's assessment of this was quite simple.

"That old man is insane!"

He knew that none of these old navy guys were easy to deal with.

Zeff has the nerve to say that Garp's training method of smashing a mountain with his fists is "nonsense"—does that mean that using your body to withstand ocean currents is not nonsense?
No, rather, is such a thing even possible?
But at this moment, it was as if one could hear Roy's doubts.

"Roy, watch closely!"

At that moment, Zefa's aura also suddenly changed.

Roy could see it clearly.

Zephyr's jet-black Armament Haki seemed to take on a tangible form at this moment.

That immense and unparalleled Armament Haki seemed to come alive at this moment, constantly flowing.

Of course, Roy knew that it was 'Ryuo' – the highest level of Armament Haki.

But at this moment, what Zephyr was using was clearly not the ordinary 'Ryuo'.

Roy could see Zephyr's feet, waist, legs, and even his bulging, knotted muscles.

Every muscle and bone in his body was constantly flowing along with the 'flowing cherry blossoms'.

Not only his skin, but even the blood flowing through his body and the veins seemed to be stained with a domineering black.

It was as if his entire body was frantically cooperating with 'Flowing Sakura', squeezing out its maximum potential.

Seeing this, Roy's eyes widened.

"Train your whole body and unleash your potential."

"This is"

Then, Zephyr's actions confirmed Roy's suspicions.

There are no fancy moves, no unnecessary actions.

Zephyr simply clenched his left fist and swung it at the 'black snake' in front of him!

"Blackbody Flow Secret Technique: Mountain Collapse!"

"Om-"

And so, Roy was startled to see it.

The instant Zephyr threw his punch, an unprecedentedly terrifying shockwave erupted.

The seawater in the deep sea was instantly split in two by that enormous, domineering force.

And on the massive, seemingly unstoppable 'black serpent' ocean current, a huge hole hundreds of meters in diameter instantly appeared.

That's right.

That massive ocean current was actually cut off by Zephyr's punch!
Roy was practically stunned.

Then, naturally, only one thought came to his mind.

"Coach, I want to learn this!"
