The Marvel of Physique, Black Body Flow!

Yes.

For Luo Yi, what was displayed on the Light Screen at this moment was his greatest gain.

Counting the two guardian deities of the Alabasta royal family and all the top-five numbered officers of Baroque Works, including Crocodile and Nico Robin.

In this operation in Alabasta, he had obtained a total of twelve Devil Fruits!

This directly allowed his Fruit Slot to unlock once more.

And the appearance of the fourth Fruit Slot was undoubtedly another massive boost for him.

But it wasn't just that.

"Special Fruit Slot."

Luo Yi looked at the content displayed in the Encyclopedia, his expression contemplative.

Clearly—the changes to the Fruit Encyclopedia had exceeded his expectations.

But at the same time, Luo Yi wasn't too surprised.

Because in fact, during his eight years of studying the Fruit Encyclopedia, he had long discovered

The Fruit Encyclopedia appeared in the shape of a book, but Luo Yi could only see the part that recorded fruits.

But the latter half of the book, Luo Yi had never been able to open—so he had actually always wondered if this golden finger of his held some other secret.

And now, it seemed the truth was indeed so.

"After collecting 60 fruits, I can unlock the fifth Special Slot, which is three times harder than unlocking a normal slot. In other words... its strength should also be three times greater?"

Luo Yi analyzed in his mind: "Fruit Fusion..."

Just the name alone was enough to let his imagination run wild.

Moreover, Luo Yi could also make more associations from this.

For example—

"As I analyze and collect more fruits, will the Encyclopedia open new pages and unlock new abilities?"

Luo Yi felt a bit of excitement, like he had finally left the newbie village and seen the vastness of the world.

However, he quickly suppressed this excitement—let alone unlocking more functions of the Fruit Encyclopedia, even just the 60 Devil Fruits needed for this 'Special Fruit Slot' were still more than half short for him now.

Dreaming about the future was good, but reaching for the sky was not appropriate.

So, Luo Yi quickly began thinking about another issue.

"Right now, I'd better recall Rooster and Dragon of the Chen to refresh their states—this way, I can grant them an additional fruit's ability."

Luo Yi was very clear on this point.

"But meeting them is a bit troublesome."

Both Rooster and Dragon of the Chen were now criminals under the attention of the World Government.

Under such circumstances, having them sneak into Marine Headquarters to refresh their states was almost impossible.

As for meeting his clones in private, that was also inappropriate—if this were discovered, his identity would be exposed directly.

In other words.

"I urgently need an ability that ensures I can meet my clones without anyone knowing in the future."

Luo Yi furrowed his brows.

Coincidentally, he actually knew of a very powerful fruit that could fulfill this requirement.

But that fruit was not located at Marine Headquarters.

"After this training with Teacher Zephyr is over, I need to find a way to leave Headquarters for a while."

And just as Luo Yi was thinking this—

"Luo Yi."

A knock came, interrupting Luo Yi's thoughts.

"Binz?"

When Luo Yi opened the door, he saw Binz standing at the entrance.

"Why are you here?"

Luo Yi asked familiarly—after this time, he and Binz had naturally gotten to know each other well.

"Teacher Zephyr sent me to take you to training."

Binz said with a smile.

"Training?"

Luo Yi was slightly stunned upon hearing this, then chuckled: "No need, I already know the way to Training Room Three very well."

He certainly didn't think he needed a guide.

But what surprised him was—

"No, Luo Yi—your training today isn't in Training Room Three."

At this, Binz gave a mysterious grin.

"Teacher Zephyr told me to take you to the center of this 'Zephyr Training Camp'—the [Training Room Zero] that only he can use."

"Oh?"

Hearing this, Luo Yi's expression shifted slightly.

Then—

"You mean..."

He looked at Binz, his tone turning serious.

And Binz nodded in return: "Exactly what you're thinking—Teacher said that starting today, you'll begin real training!"

With that, he turned and walked away. "Follow me."

So Luo Yi took a deep breath and followed.

Soon, after trailing Binz through a maze of various training rooms, Luo Yi arrived at 'Training Room Zero.'

This training room was unprecedentedly vast, and Luo Yi immediately recognized that the surrounding walls were also made of special 'Z Alloy.'

But what stood out most was the center of the room.

There stood a platform, and atop it was a massive pipe-like structure.

At that moment, 'Black Arm' Zephyr was standing on the platform.

Upon seeing Luo Yi, Zephyr grinned.

"What's the matter—been getting impatient? Thought this old man was lying to you?"

Zephyr laughed heartily.

"Honestly, a little. If it weren't for you, Teacher, I'd have reported this place for fraud by now."

Luo Yi replied with a straight face.

Then, the master and disciple, now well-acquainted, exchanged a glance and shared a smile.

"Come on up—this is where you'll train."

Zephyr beckoned, and Luo Yi, without a word, stepped onto the massive platform with a solemn expression.

Then—

"..."

Nothing happened.

"?"

Luo Yi, who had already tensed every muscle in his body, looked at Zephyr with some confusion—Old man, what are you doing?

"Don't rush."

Seeing Luo Yi's puzzled look, Zephyr burst into laughter again.

"I told you, you have enough talent, so the training you'll receive is a bit unique."

"But before that, I need to ask you—what do you think of my strength?"

What do I think of his strength?

Hearing this, Luo Yi glanced at Zephyr with some doubt.

"Teacher Zephyr, you're naturally very strong. To be precise, you're the strongest person I've ever fought."

Then, he answered sincerely.

It was the obvious response.

Even now, he still remembered the punch he'd exchanged with Zephyr last time.

In that punch, Luo Yi had genuinely used one of his strongest fruit combinations in terms of physical strength.

Though he couldn't reveal his identity as an Ability User, preventing him from using his strongest Beast Form or Human-Beast Form to fight Zephyr, even so, the combination of the Wind God Pterosaur Fruit, the Great Rhinoceros Fruit, and the Strong-Strong Fruit was already formidable enough—in that state, he was confident he wouldn't lose even in a contest of strength with a Sea King.

Yet, facing Zephyr's serious punch back then, he was still sent flying.

Even an old, retired, crippled Admiral who had lost his prime was still an Admiral—they symbolized the true pinnacle of individual power across the entire sea.

And Zephyr clearly appreciated Luo Yi's sincere answer.

The old man chuckled happily, then continued asking, "Then where do you think my strength lies?"

"Haki, of course."

Luo Yi answered without hesitation.

Zephyr's epithet was 'Black Arm'.

From this, it was clear that his greatest strength lay in his Armament Haki.

This was also what Luo Yi most wanted to learn—with Armament Haki, dealing with Logia users would become far more convenient.

After all, not every Logia user happened to be countered by him like Crocodile was.

But—

"Right, but also wrong."

Hearing his answer, Zephyr spoke softly instead.

"Haki is only the result, Luo Yi."

He looked at Luo Yi. "The true answer is 'physique' and 'technique'."

He continued on his own, laying out the conclusions he had reached over so many years.

"Logia, Zoan, Paramecia—Devil Fruit users possess unique, heaven-granted talents and abilities, born surpassing ordinary people by nature."

"For non-users like us to catch up to them, we can only rely on physique and technique."

He didn't notice that when he said the words 'non-users', Luo Yi's expression turned somewhat strange.

Zephyr looked at Luo Yi, speaking word by word.

"Precisely because he understood this, Garp created his own 'Iron Fist'."

Hearing this, Luo Yi naturally understood what Zephyr meant.

Almost everyone at Marine Headquarters knew—the 'Marine Hero' Garp had a unique training method.

Without using Haki or abilities, purely with his own fists, he would punch the Seastone lining the bottoms of warships, blow after blow.

Year after year, year after year, constantly tempering his own 'fist bone'.

Until finally, without even using Haki, a single punch could shatter a mountain or a small island into pieces.

That was why he had earned the epithet 'Iron Fist Garp'.

And now, Zephyr's meaning was equally clear.

"Like Garp, I too have my own unique training method and exclusive body techniques."

There was unmistakable pride in Zephyr's words.

"Unlike that reckless fool Garp, who concentrates all his power into his fists—what I pursue is the tempering of the entire body."

He looked at Luo Yi, clear expectation in his eyes.

"This is what I will teach you."

With that, he raised his left fist.

"I'm used to fighting with my hands, which is why people call me 'Black Arm'."

"But in truth, whether it's skin, bone, muscle, organs, or even blood—the perfect body technique that tempers and awakens the potential of every part of the body is the true essence of my martial art. Its name is... 'Black Body Flow'."
