One Piece: Nobody knows Devil Fruits better than me.

Chapter 1: Loy Amos, an unremarkable naval lieutenant!
Haiyuan calendar, 1517.

The Grand Line, a certain sea area.

Two naval warships are docked here, and seagulls carrying the naval ensign of the naval fleet flutter in the sea breeze.

The markings on one of the warships are the standard 'MARINE'.

Those are ordinary warships that symbolize the navy.

The other warship was marked with the words 'DT-31'.

That symbolizes a special logistics unit within the navy, the 'detention force' responsible for escorting defeated criminals.

"Bounty of 4700 million Berries, 'Gladiator' Antonia has been captured and handed over—the warship that captured the prisoner is numbered T-14551 and belongs to Major Gushir of Headquarters."

At that moment, Loy Amos watched as the burly man was brought aboard his warship while he spoke into his recording Den Den Mushi to take notes.

After finishing his recording, he looked at the naval officer on the warship in front of him and said, "Thank you for your hard work, Lieutenant Commander Gushir."

"It's all for justice."

The naval lieutenant commander named Gushir chuckled before reminding him, "But I must warn you, Captain Roy—this guy is quite formidable. You'd better make sure you don't remove the Seastone handcuffs throughout the entire escort."

"I don't care about arresting him again, but I don't want to hear the news that your warships have been sunk by criminals at sea, hahaha!"

He burst into laughter as he said this.

Upon hearing this, the marines in the detention unit behind Roy's face darkened.

But Roy didn't care about the teasing in the other person's words, and simply smiled and nodded: "Thank you for the reminder."

Having said that, he turned and leaped back onto his warship: "Return to Marineford."

"Yes, Captain Roy!"

His marines saluted in unison and then busied themselves setting sail back to port.

but
"Seriously, what's that guy so smug about? - Far, tell me, aren't we all Marines? He's so proud of himself for catching a guy with a 40 million bounty. Last time, Admiral Kuzan caught a pirate with a 300 million bounty, and he wasn't this cocky!"

As a naval officer escorted a criminal into a specially constructed temporary cell inside the ship's cabin, he couldn't help but mutter to his companion beside him.

"Let's keep quiet, Hans. There's nothing we can do about it, after all, we're a detention force."

Upon hearing this, the navy officer named Far shook his head helplessly.

This was clearly not the first time they had been treated this way.

The reason is quite simple—the detention unit they belong to is rather special within the navy.

Their main responsibility is to escort criminals who have been captured in various sea areas. Under normal circumstances, they do not participate in front-line combat, but they can receive a share of the corresponding military merits after bringing the criminals back.

Therefore, in the eyes of many naval personnel, those who are detained are the kind of cowards who refuse to participate in battles but insist on joining in to claim credit.

What's wrong with the detention forces?

The marine named Hans was even more unhappy: "We've encountered dangers when we escort criminals, and besides, we don't get much credit each time."

He mimicked Major Gushir's tone: "I wouldn't mind arresting him again, but you'd better watch out. What nonsense are you spouting!"

But as he finished speaking, a low shout rang out: "Sergeant Hans!"

"Yes, Captain Roy!"

Hans immediately straightened up, instinctively saluted, and looked behind him.

Behind him, a black-haired, blue-eyed captain had appeared at some point.

What did I tell you before?

Roy looked at his subordinate with a half-smile.

"Complain less, do more."

So Hans said somewhat guiltily.

"It's too quiet, I can't hear it at all!"

"Less complaining, more doing, sir!"

"Good! Very energetic!"

Roy waved his hand: "Get back to the helm immediately—the old rule, I'll personally take charge of the first night guarding the criminals!"

"Yes!"

Hans felt as if he had been granted a pardon and quickly gave Fal a wink.

The two ran towards the exit of the makeshift prison, but before they arrived, they didn't forget to ask, "Sir, do you want me to bring you some food after dinner is ready?"

"Pizza and Coke, please."

Roy waved his hand and emphasized, "The cola must be ice-cold!"

"Yes!"

So the marines left the cabin.

Only the enormous 'gladiator' Antonia, wearing seastone handcuffs, remained, leaning against the wall of the prison and looking at Roy.

"It sounds like you and your subordinates aren't very popular within the Navy?"

He chuckled.

"That's it."

Roy sat down on the sofa in the cabin and casually took an hourglass from his pocket and placed it on the table.

The sand in the hourglass began to flow away, and he casually turned his head to look at Antonia.

"However, it's said that Marshal Sengoku is already considering elevating the status of the detention troops. Hmm, what's up? Do you have something to say about that?"

He didn't seem to mind having a heart-to-heart talk with the criminals.

"No, it has nothing to do with that!"

But Antonia whispered, "It's only because you're too weak—if you were strong enough, no one would dare to underestimate you."

"Status, money, power—you need sufficient strength to acquire them. Look at Lao Tzu!"

He struggled to sit up straight: "If it weren't for these handcuffs..."

At this point, he looked at a huge iron plate not far away—atop the iron plate was a protrusion that resembled a 'grip'.

Those were his weapons, which were handed over along with Antolia. "With my 'Iron Fist,' I can easily kill you with a single, full-force strike, and then shatter this prison."

Antolia scoffed at this.

But he discovered that Roy seemed completely unconcerned about his 'provocation'.

"Ah, yes, yes."

He nodded with a serious expression.

then
"but."

He changed the subject: "You only managed to shatter this small prison with your full power? You're supposed to be a muscular man who ate the Strength Fruit, are you really that weak?"

".ah?"

Antolia was almost completely bewildered.

It took him a long time to realize what Roy had said, and then anger visibly ignited in his eyes.

This navy man, this guy named Roy—how dare he humiliate me like this?

What did you say?

But before Antonia could utter his angry curse, his words caught in his throat, and his eyes nearly popped out of their sockets.

Because at that moment he saw that Roy had casually picked up the huge iron block 'Iron Jun' that was placed not far away.

That heavy, massive iron block, whose weight alone would be enough to crush a small building, was lifted by Roy as easily as picking up a balloon.

"Hmm, judging from the weight of the weapon you're using, you can only increase your muscle strength by about twenty times at most? Then you're not very good at developing your Devil Fruit ability?"

He made this sharp comment.

"you you you."

At this moment, Antonia was almost speechless.

The scene before him made him feel like he was dreaming.

"wrong."

It wasn't until a moment later that he seemed to wake up from a dream.

How did you know I ate the Fruit of Strength?

"Ah, about that."

At this moment, Roy casually put down the huge iron block and sat back in his seat.

"I know a tiny bit about Devil Fruits."

He spoke casually, but his gaze fell on the hourglass on the table.

A third of the sand in the hourglass had already flowed out, which made Roy nod in satisfaction.

"Yes, the timing is perfect."

"Time? What time?"

Hearing this, Antolia became even more confused.

But the next moment, he saw Roy reach out his hand to him.

"It's nothing—get some rest."

As the words fell.

Antonia felt a tremendous impact suddenly come from her.

Then everything went black.

"boom!"

His massive body collapsed to the ground, and he lost consciousness.

But Roy didn't look at him again.

He simply looked up at the air in front of him.

From his perspective, there was an illusory light curtain in the air.

[Analysis progress: 33%. Upon completion, you will gain the fruit's ability at level 1]

Looking at the light screen, Roy's expression remained calm.

In his eyes, 'Gladiator' Antonia was just an ordinary, mediocre Devil Fruit user.

But there is one thing he does agree with: the other person is absolutely right.

That is.
“Strength is everything – on this chaotic sea, you can’t be safe anywhere without strength.”

He looked at Antolia, who had already fainted.

The difference between you and me lies in our perspective.

“I know how vast this sea is, so I chose to stay in the detention center.”

"And you know nothing about this, which is why you said those ignorant things just now—go to Impel Down for further studies, the people there are very interesting and speak very nicely, you will definitely like it there."
