It's Time to Show My True Talent! Give Me More!

Black Body Flow.

This name wasn't exactly eye-catching, but at this moment, it stirred a longing in Luo Yi's heart.

He mused that no wonder Zephyr could teach a kick specialist like Kizaru, and also a fist king like Akainu, who only used his legs for walking.

It turned out that the old man's physical techniques weren't just "fist arts"—they were a full-body martial discipline.

So right now, he was quite excited.

Because he also knew—physique and physical technique were indeed the foundation of everything.

Even for an Ability User, this held true.

Not to mention that using a Devil Fruit Ability itself consumed stamina.

Just a strong physique and solid physical techniques alone could grant an Ability User a massive boost.

Take the Marine Admiral "Aokiji," for example.

As Garp's disciple, he had learned "Iron Fist" and successfully mastered it.

Combined with the Freeze-Freeze Fruit, the power of his iron fist was enough to be called terrifying.

And for Luo Yi—he had a Devil Fruit Ability with almost no upper limit. If he could also wield a sufficiently powerful physical technique to perfectly unleash his ability, then he wouldn't be far from truly standing at the top of the world!

But amid his excitement, Luo Yi also felt some confusion.

If Zephyr's "Black Body Flow" was just about tempering the whole body, then theoretically anyone should be able to learn it.

Just like Garp's Iron Fist.

As could be seen from the young Koby, who would only join the Marines a few years later.

As long as one wasn't afraid of breaking their arms, anyone could train in "Iron Fist."

Yet Zephyr, after all these years, had never truly found an heir to his teachings. That was quite strange.

At this moment, Zephyr seemed to sense Luo Yi's confusion.

But he didn't explain, only shook his head: "Black Body Flow is somewhat special—Ability Users cannot train in it at all, and most people can't withstand the training environment."

Having said that, he glanced at Luo Yi.

"I observed for a long time before I was sure you wouldn't lose your life over this—you'll know the specifics soon enough."

"Ah?"

Luo Yi let out an "ah" in response: "Did I hear that wrong? Did you just say something about 'lose your life' or something?"

That sounded a bit unsettling.

Before he could finish speaking, he saw Zephyr nod at Binz.

Binz went straight to a corner of the training room and found an operating panel there.

"Hey, wait, I—"

Luo Yi tried to say something, but didn't get the chance to finish.

The next moment.

Click!

As Binz pressed a button on the panel, the platform beneath Luo Yi's feet split open.

Luo Yi could even see a hollow void below the platform.

At the end of that void, he could see the blue seawater!

"Get ready, we're heading out!"

At that moment, Zephyr laughed heartily.

"Hold on—"

Before Luo Yi could react, he saw the pipe above his head suddenly extend downward.

Boom!

A blast of wind pressure of extreme intensity slammed into him, and Luo Yi instantly felt his body uncontrollably fall through the pipe.

Seeing this, Zephyr didn't hesitate either. He leaped straight down after him.

After falling for quite some time...

Thud!

With a heavy landing sound, he finally hit the bottom.

Hiss!

Of course, with Luo Yi's physique, a fall that would have sent an ordinary person to reincarnate ten times over only made him hiss softly.

Thud!

Right after, Zephyr also landed heavily from above.

It was only at this moment that Luo Yi clearly realized—he and Zephyr were still inside that same pipe.

The pipe was semi-transparent, with a faint hint of rainbow-colored matter wrapped inside, while beyond it lay a pitch-black stillness.

"Coating?"

Luo Yi instantly recognized the origin of that rainbow-colored matter—the unique coating technology of this world.

"Is this... the deep sea?"

So he immediately realized where he was.

"Correct, this is 5,000 meters below the surface—the limit reachable via the SSG's specially made 'Coating Extension Pipe.'"

Zephyr nodded, casually pulling a Coating Bubble from the pipe beside him and placing it over Luo Yi's head.

"And this is your first lesson."

Hearing this, Luo Yi was stunned.

He had a vague guess forming in his mind about what Zephyr meant by 'first lesson.'

And sure enough.

The next moment, he saw Zephyr grin wide, flashing a mouthful of white teeth.

"Go!"

With that low shout, he lifted his foot and kicked Luo Yi square in the rear.

Before Luo Yi could react, he was booted straight out of the pipe—the pipe itself, made of some unknown material, seemed to be as penetrable as a layer of coating.

The instant he left the pipe.

"Ugh!"

Luo Yi felt the icy seawater swallow his body whole.

Then he felt it. Pain!

An excruciating pain wracking his entire body.

Every inch of his skin, every bone and muscle, even every cell seemed to be hammered by a tremendous force.

Luo Yi could even hear the cracking sound of his bones and muscles being torn apart.

He knew exactly what this was—the water pressure inevitable in this deep sea, enough to crush steel into a flat disc!

Back in the coating pipe, Zephyr watched the scene, his slightly tense body relaxing a little.

His voice, transmitted through the coating, pierced the seawater clearly into Luo Yi's ears.

"Feel it, Kid Luo Yi?"

He said.

"We must temper every part of the body—this is extremely difficult. Normal training, no matter how precise, can never equally hone every part of the body; there will always be weak points."

"But the sea can help you."

The Admiral's words carried unmistakable pride.

Using the deep sea as a hammer and water pressure as an anvil to forge the physique of a Strong Person—that was the basic logic of the 'Black Body Flow' he had researched and practiced to this day.

Hearing this, Luo Yi, still dazed, suddenly understood.

"No wonder it requires an incredibly powerful physique and recovery ability, and Ability Users can't train in it."

Training in the 5,000-meter deep sea? It would be strange if an Ability User could manage it.

At that moment, Zephyr continued speaking.

"But don't think that's all there is to the Black Body Flow."

"I've tested your physical data over this period. Quite impressive, but still not enough—far worse than I was back in the day."

Zephyr said solemnly.

"So for now, you still can't undergo formal training. I've set a goal for you: adapt to the water pressure here within a month."

"Once your body becomes tougher, I'll take you for real training."

His tone was stern, like a homeroom teacher saying, 'You're the worst class I've ever had.'

But in truth, Zephyr's eyes were full of admiration.

Because Zephyr knew well—his words were half true, half false.

He had indeed accurately judged Luo Yi's physical strength through this period's tests, which was why he dared to bring Luo Yi here.

Luo Yi's physique was indeed still a bit short, needing time to adapt to the water pressure here.

But—

"To come here without using Haki... he's already a Monster."

Zephyr was well aware of this.

Back in the Marines, he had been a true genius, rarely encountering opponents except for a handful like Garp and Sengoku.

And he had indeed created the 'Black Body Flow' at 5,000 meters underwater—but by the time he created it, he was already a top-tier Haki master.

He had only managed to train here after a considerable amount of time, relying on the dual effects of Haki and physical constitution.

But Luo Yi couldn't use Haki at all, yet he could directly withstand the water pressure at 5,000 meters with just his physical strength—this was a genuine monster's physique, far surpassing Zephyr's younger self.

This was also the source of Zephyr's expectations.

Back in the day, he had taken many detours while developing the 'Black Body Flow'.

By the time the Black Body Flow was perfected and complete, he was already quite old, his body had passed its peak, and old injuries prevented him from fully unleashing the limits of the Black Body Flow as he had envisioned.

But—

"He can."

Watching Luo Yi's face contorted under the crushing water pressure, Zephyr felt boundless anticipation in his heart.

But at that moment.

"Adapt for a month, then start formal training? You mean this isn't even the real training yet?"

Right now, Luo Yi naturally had no idea what Zephyr was thinking, so he could only frown inwardly.

"Just adapting alone takes a month, and if I add the formal training after that, it'll take way too long."

Luo Yi muttered under his breath.

"I still have things to do next."

So—

"It's time to show my true talent!"

"Fruit Encyclopedia—give me. Add points!"
