One Piece: Nobody knows Devil Fruits better than me.

Chapter 10: Pay attention, I'll only teach you once.

Two hours later.

Inside the Navy's G-51 branch, the banquet was drawing to a close.

Most of the sailors who couldn't hold their liquor were already passed out drunk, and the remaining sailors were mostly half-drunk.

"That captain from headquarters today, what's his name, Roy? He's such an ungrateful bastard."

However, at this moment, Steward Mantal, who was in the center of the banquet, was not yet drunk.

He was saying it aloud.

"Yeah—just some guy from the detention center, how dare he talk to us like that!"

In front of him, Colonel Astor downed his enormous glass in one gulp and slammed it heavily on the table.

"If I hadn't been transferred to the branch, I would definitely have taught him a lesson today!"

He lowered his voice and said.

According to naval regulations, naval officers transferred to branches have extremely high authority within the branch's jurisdiction.

However, the officers at the Naval Headquarters are not under their jurisdiction—because each marine at headquarters has a direct subordinate officer at the Naval Headquarters, and they are managed independently of each other.

For example, as a captain in the detention unit, Roy's direct superior was Lieutenant General Bilos of the headquarters.

So although Colonel Astor was very unhappy with Roy's cold and hard attitude today, there was nothing he could do.

"Don't rush, Colonel Astor."

Upon hearing this, Steward Mantal grinned.

He lowered his voice and said, "The treasure you transported for us this time is part of the 'Heavenly Gold,' which is a great achievement. I will explain your contribution to His Majesty the King."

"When the World Conference comes three years from now, His Majesty the King will definitely be happy to praise you to the World Government's top officials. At that time, you might be promoted to General of the Headquarters."

Perhaps it was because he had drunk too much, which made him make grander promises than usual.

"Really?"

Colonel Astor was certainly tempted by the idea.

"Of course it's true—you know, the Celestial Gold we prepared this time is a full 50 billion Berries, which also includes a Devil Fruit. That's more than 10 billion Berries more than the government asked us to hand over."

"This extra billion is used to bribe the important people in the government."

"I'm a manager," said Mantal with a smile.

Colonel Astor quickly refilled his glass: "Then I'll trouble you, Steward, to put in a good word for me with His Majesty the King. I'll drink this in one gulp!"

"Not at all! We'll need your continued support in the future, Your Excellency Brigadier General Astor!"

For a time, both host and guests were delighted.

But it is precisely at this moment
"Drip!"

"Drip!"

The piercing alarm sounded throughout the entire G-51 branch.

"Huh!? What's going on!?"

This immediately made Colonel Astor frown, and he looked at a marine beside him who was not yet drunk: "Go and check right now. Did some guy drink too much and accidentally trigger the alarm?"

"Yes!"

The marines accepted the order and left, returning shortly afterward.

But when he returned, his expression clearly showed panic.

"Sir, it's the port! A ship has run into trouble at the port!"

He said anxiously, "The Eckyon has left the port, and all of the Eckyon's guards have been killed and their bodies have been dumped in the port."

"What!?" *2
Upon hearing this, Colonel Astor and Steward Mantal sobered up instantly.

"That pirate... could he have accomplices?!"

Colonel Astor immediately considered this possibility.

Manager Mantal, on the other hand, was pale.

It's important to know that the Ekjorn is a royal merchant ship worth 200 million Berries, and its guards are also royal guards.

Now that all the guards are dead, if the ship is lost as well, he'll be lucky to escape punishment, let alone achieve any merit on this voyage!

"Immediately organize a pursuit! Send out all warships; we must bring the ship back!"

Colonel Astor was clearly aware of this, and so he spoke up immediately.

"But sir."

But the marine looked somewhat embarrassed at the drunken marines around him.

Colonel Astor's expression grew even more grim: "Leave a few men to help them sober up, the rest of you go after them immediately! Right now!"

Seeing his expression, the Marine naturally didn't dare to say anything more.

And after he left with his men...

At that moment, Steward Mantal looked at Colonel Aster as if he had just remembered something, and their eyes met.

The next moment, the two of them hurriedly left the banquet.

"Colonel Astor, do you think the other side might be after the treasure?"

At this moment, Steward Mantal's fat face had turned deathly pale.

That's right.

This is what he fears most at this moment.

The Ekjorn was taken away and its guards were killed. These things made him anxious but not panicked.

But if the treasure he hid in the naval branch, which was part of the 'Heavenly Gold,' were stolen, then the best outcome for him upon returning to the Kingdom of Nismair would be death.

"Don't worry, it won't happen."

Colonel Astor was clearly anxious at this moment, but he managed to remain calm.

"Only we know the location of the treasure room, and you have the key to the treasure chest. The attackers sailed away with the Ekjorn, probably mistakenly believing that the treasure was still on board."

Upon hearing this, Steward Mantal grasped at a straw: "Yes! You're right! That must be it!"

Before they knew it, they had arrived at the basement of the G-51 branch.

There are many storage rooms here – these are for storing the branch's supplies.

At this moment, they arrived in front of a huge weapons cabinet.

Colonel Astor then gently tapped a wooden board on the weapons cabinet.

then
"Boom!"

With a loud noise, the weapons cabinet slowly moved aside.

The storage room at the back was revealed, along with the mountain of treasure chests inside.

Only when he saw that the treasures were still in the same place did Steward Mantal finally breathe a sigh of relief.

"Thankfully, it's still there."

He seemed to have regained his spirits: "Colonel Astor, I'll have to ask you to make sure the Eckyon is safely in service."

As he finished speaking, Colonel Astor's expression changed.

Because at that moment, he had already heard a huge noise coming from behind him.

"Boom!"

It was as if a giant rhinoceros had charged at him from behind; the piercing sound made Colonel Astor tense up instantly.

"careful."

He turned to give a warning to Steward Mantal, but before he could speak, he felt a tremendous force coming from his back.

The same was true for Steward Mantal—Colonel Astor even saw a fist slam into his massive back, the force of which instantly deformed his body. "Crack."

He even heard the sound of the other person's bones completely shattering.

The next moment, both of them were blasted away.

"boom!"

They crashed heavily into the thick wall of the storage room, instantly creating a huge crater.

Amidst the rising dust, a figure slowly entered the storage room.

"When people are panicked, they will subconsciously try to protect their most precious things; this is common sense."

Wearing a rooster mask, Roy stepped into the storage room.

"Thank you for showing me the way."

As he said this, he looked at the piled-up treasures with a hint of satisfaction in his eyes.

However, he did not immediately go forward to touch the treasure chests.

Instead, he turned his head to look into the smoke and dust.

"However, I didn't expect Colonel Astor to be so resilient than I thought."

As he spoke, Colonel Astor did indeed emerge from the smoke and dust.

At this moment, the naval captain's uniform was completely torn apart, revealing his muscular upper body.

At this moment, his muscles were bulging, looking like pieces of steel.

At that moment, Colonel Astor spoke in a hoarse voice: "Iron Block Hardwood."

As he spoke, his gaze swept briefly over Steward Mantal beside him—who was now in a tucked-up position, his head, neck, and body folded in three places, clearly beyond saving.

"You bastard! How dare you kill the royal steward of a World Government member state?"

He clenched his teeth, as if he were extremely angry.

Upon hearing this, Roy shook his head: "First of all, I don't understand why you guys have this obsession with shouting out the name of the move before you start fighting."

"Secondly, I was just cleaning up a scumbag as the so-called royal steward."

He scoffed.

Then, he looked at Colonel Astor in front of him: "And you, you're scum too, you have to be cleaned up as well."

"Humph!"

Upon hearing this, Colonel Astor sneered.

He waved his hand, and his muscular arms dispersed the surrounding dust.

"Who do you think I am? I am Astor Campbell—Navy Captain, the commander of Branch G-51!"

He walked step by step out of the ruins on the ground and put on his navy coat.

"I trained hard to master the 'Naval Six Styles,' a physical technique that surpasses human limits."

"You bastard who appeared out of nowhere, you think you can kill me!?"

His voice was full of fighting spirit.

Upon hearing this, Roy became slightly more serious.

In fact, Colonel Astor's abilities did exceed his expectations.

Within the Navy Headquarters, it's not difficult to find a way to learn the Six Styles.

The difficulty in learning this thing lies mainly in physical fitness—you need a physical strength of over 500 points to possibly learn the Six Styles, and the stronger your physical strength, the easier it is to learn.

Therefore, a naval officer who can master the Six Styles is definitely considered to be of above-average ability among his colleagues.

So he never expected that someone like Colonel Astor would actually possess the 'iron block' among them.

However, considering that the other party is, after all, the naval branch manager of the Grand Line, it is normal for them to have this strength.

"Then I'll take it a little more seriously."

Seeing the opponent's fierce fighting spirit, Roy clenched his fists, preparing to warm up his body a bit.

And it was precisely at this moment.
"Ready? Intruder—I'll show you the power of the Navy's Six Powers! Take this! Tempest Kick: Wind Slash!"

Colonel Astor gave a low shout and stomped his right foot hard on the ground.

then
"boom!"

To Roy's astonishment, the other party shot off like an arrow toward the exit of the storage room!

"Run away!?"

Only now did Roy finally realize what was happening.

That's bullshit! They're clearly trying to escape!
And this is indeed the case.

At this moment, Colonel Astor, who was fleeing at top speed, had no intention of fighting.

In fact, if you look closely, you will find that there is a ferocious fist mark on his back—it was just that he had covered it up with his coat before.

"That guy is a monster; fighting him is suicide. The only option is to run..."

As he endured the pain and fled, he roared inwardly.

"My iron block is no match for his attack."

This was also what made him most panicked and fearful.

He did indeed master one of the Six Styles, 'Iron Body,' which was his proudest achievement and the biggest reason he was promoted to colonel.

But from that punch, countless bones inside his body were broken, centered on the fist mark.

This led him to make a decisive judgment—fighting was suicidal, and running away was the only way to survive.

As he fled in panic, Colonel Astor turned his head.

Then he saw Roy still standing there.

"He couldn't catch up, so I succeeded!"

This scene filled him with immense joy.

But the next moment...
"As expected. There are no warriors among the scum who associate with slave traders."

Colonel Astor, however, heard a calm voice from the other party.

"Didn't you say you wanted to show me the power of the Six Styles?"

"But it seems you're not very good at the Tempest Kick."

then
Colonel Astor saw the other man slowly raise his right foot.

Without a sound, he seemed to see the other person's legs grow even thicker.

[Rabbit-Rabbit Fruit - Snow Rabbit Form - Leg Enhancement]

[Ox-Ox Fruit - Giant Rhinoceros Form - Leg Enhancement]

"Since that's the case, watch carefully, I'll only teach you once."

As soon as he finished speaking, Roy kicked out.

"Storm Kick - Wind Slash!"

The name of the move is exactly the same as Colonel Astor's.

The next moment, Colonel Astor saw something incredible.
The ground crumbled and split open in an instant, forming huge ravines as the slashing attack swept through.

The stone wall tiles inside the storage room shattered instantly.

That's right.

What was kicked out from the opponent's foot at that moment was a huge slashing blade of energy that was over five meters long!
That was also the last scene he ever saw in his life.
