I trained all the Luffy pirates into generals.

Surrounded by a group of navies.

Karp and Roy stand on the beach by the sea.

"You strike first, let the old man see your attack methods!"

Karp said softly.

In Karp's opinion, the direct age and strength are much stronger than Roy, and it should be allowed to let Roy.

"Good!"

Roy nodded.

In the face of the top combat power of the pirate world, he did not slack off in the slightest.

"Fire Escape Hao Fireball Technique!"

Roy directly froze and spewed out a huge fireball from his mouth to attack Karp.

"This is the Devil Fruit ability??"

The navy watching the battle, after seeing the flames spewed out of Roy's mouth, subconsciously thought that it was the Devil Fruit ability.

"Huh?"

Karp was also a little stunned after seeing the huge fireball spit out of Roy's mouth.

This fireball reminded Karp of Ace, who ate the ability to burn the Devil Fruit!

It's just that Ace, who he treats as a grandson, has joined the Whitebeard Pirates, one of the Four Emperors.

This made him a little heartbroken.

"It's not the Devil Fruit ability!"

Luffy said arrogantly on the side.

Luffy heard his master Roy say that this is called ninjutsu!

"Not a Devil Fruit ability?"

After hearing Luffy's words, Karp became interested in Roy for a while.

He was really surprised that he didn't have the ability to eat the Devil Fruit, but he could perform a move like the ability to burn the fruit!

"Lieutenant General Karp be careful!"

The navies saw that the fireball was about to explode in Vice Admiral Karp's face, but Vice Admiral Karp still did not respond, and hurriedly reminded in a little panic.

I saw that Karp raised his right fist slightly casually while being reminded by the navy.

Then smash a punch into the flying fireball!

boom！

The huge fireball, after being hit by Karp's iron fist, directly spread out like fireworks.

"This move of yours is powerful, and it can already threaten the existence of the colonel level!"

Karp after defeating the fireball released by Roy.

Commented on Roy's fireball technique.

"yes, what about this trick!?"

"Fire Dragon Fire Art!"

Roy froze and spat out a huge fire dragon from his mouth to attack Karp.

The Hao Fireball Technique just now is just 'C' level ninjutsu.

And the C-level fireball technique released by Roy can threaten the existence of the captain level of the navy headquarters.

What about the B-level Dragon Fire Art!

Karp put away his contemptuous look after seeing the fire dragon spit out of Roy's mouth.

Then cover the armed color domineering on your right fist and swing your fist at the attacking dragon head!

'Fist'!

boom！

The huge fire dragon also exploded under Kapu's punch wrapped in armed color domineering.

"This move of yours is already stronger than most of the rear admirals in our naval headquarters!"

Karp commented.

In terms of power, this move is no longer weak, and the fire fist cast by Ace is no longer weak.

"Roy, how about you join our Navy!?"

"I admire you, you join me and I can make that old guy of the Warring States be promoted to major general with a broken reward!"

Karp invited again.

This time Karp's invitation, the surrounding naval soldiers have already had the same idea as Karp after seeing Roy's strength.

"Lieutenant General Karp, thank you for your kindness, I understand it!"

Roy shook his head in refusal.

Even if he was offered the post of lieutenant general after he joined, he would still refuse.

"That's a shame!"

Once again, Karp lamented.

"Those attacks you just attacked me were just temptations!"

"Let me see what you're really capable of!"

Karp said.

Since he taught Luffy the secret technique that can instantly raise his strength to another level, then Roy will definitely use it!

"Good!"

Roy nodded.

He originally thought that by casting the B-grade Dragon Fire Technique, he would be able to test a little of Kapu's strength.

But as the Dragon Fire Art was easily dissolved by Karp, he knew how unfathomable Karp's strength was.

So.

When Colonel Gerry and Luffy fought not long ago, the Navy Type Six 'shaving' used disappeared from the place in an instant.

When Roy's figure appeared again, he had already appeared behind Karp!

"Fist gun!"

Roy smashed his right hand, covered in armed domineering, into the back of Karp's head.

However, Roy's attack angle has long been perceived by Karp's domineering.

After anticipating Roy's punching from the rear, Karp quickly turned around and punched Roy with his right hand covered in armed color domineering.

Bang!

Two pitch-black fists collided together, at the same time as a loud crash.

Along the impact point, waves of white gas also spread.

And after the fist!

Roy took dozens of steps backwards, while Karp remained standing in place.

"It is worthy of being a man who stands at the peak of this world!"

Roy took dozens of steps back, and even though there was an armed color domineering covering, his hand still hurt a little.

"You can be domineering!?"

Karp was also a little surprised!

After Karp discovers that Roy is domineering, he completely admits that Roy is qualified to teach Luffy.

After Karp found out that Roy would be domineering, he began to let go of his hands and feet and took the initiative to attack Roy!

"Flying Fist!"

Karp threw his fist, and a huge air fist print was punched out by it to attack Roy.

In the face of Karp's attack, Roy had already predicted in advance by seeing and hearing the domineering, and then cast the Navy Six 'shaving' to move sideways to the right and easily dodged.

However, while Roy dodged Kapu's flying fist attack, Karp had already cast the 'Navy Six' shave and instantly came to Roy's side.

And swung out a domineering right fist wrapped in armed color!

Bang!

A bang!

Roy was smashed directly into the bunker!

"Worthy of Lieutenant General Karp!"

"Lieutenant General Karp is still so powerful!"

"Will this punch seriously injure that Roy!"

The soldiers watching the battle around cheered when they saw Karp smash Roy under the beach with a punch.

However, while the naval soldiers cheered, Karp frowned and looked at the dusty smoke on the right!

As the dust cleared, Roy's intact figure appeared in front of everyone!

"In the instant just now, two of you appeared!?"

Karp looked at Roy and frowned and said.

The other naval soldiers were also a little confused.

Roy was clearly smashed into the bunker in front of him, and the frown will appear ten meters away to the right of the bunker?

"This is my master's doppelganger!"

Luffy said for his master with some pride.
