Sailing: Start by plundering Koby's entry!

"Woo! Muscle Balloon!"

Luffy's right arm, which was filled with Armament Haki, began to move strangely.

This blow not only blew the air into the bones and muscles, but also blew the armed color domineering into them.

Human-Human Fruit - Mythical Beast - Nika Form. Although before awakening, the ability user can only have Nika's rubber body,

But this rubber is no ordinary rubber!

But it's Nika's rubber!

Not only can it stretch and contract, its true power is to accommodate and hold everything!

Including, the power of Armament Haki! It's not entangled! It's not hardened! Instead, it directly integrates into the muscles and bones.

The perfect fusion of Armament Haki and the Devil Fruit body created by the Devil Fruit,

Nika's power began to show.

"call out!"

The Armament Haki and air in the giant muscle balloon arms began to surge and injected into Luffy's body.

Luffy's body expanded rapidly, becoming a being with a height of more than 3 meters and an extremely expanded body.

A demon's domineering pattern appeared on Luffy's chest.

"Dang! Dang!"

Luffy's arms and legs are infused with amazing Armament Haki.

The constant elastic force from his feet made it impossible for Luffy to fight normally, and he kept bouncing on the ground.

"Gear Four! Stretch-Man!"

Luffy had black eye shadow, and because of the swelling, his voice changed slightly, and he spoke in an exaggerated tone.

"In this position, the elasticity of the rubber is making it difficult for you to stand steadily."

The flying squirrel said calmly as he watched Luffy bounce up and down.

"I will beat you until you are unable to fight back, and send your head to Lu En as a gift!"

After starting Gear Fourth, Luffy's eyes were filled with a hint of evil.

"Rubber rubber!"

Luffy's arms began to contract like springs.

The Armament Haki is perfectly integrated into Luffy's rubber body. The power of Haki can also enjoy the increased elasticity brought by Nika's rubber body!

Luffy's Armament Haki in Gear Fourth is one level more powerful than his usual Armament Haki!

"boom!"

Luffy's feet turned into elastic devices, allowing Luffy to dive directly.

Luffy in Gear Fourth can fly! His agility and speed surpass those of Moon Step.

"what?!"

The flying squirrel's pupils suddenly shrank.

He could only withstand such a fast attack.

"Rubber rubber! Ape King! Gun!"

The elastically enhanced Armament Haki right fist slammed heavily onto the flying squirrel's knife.

“Boom! Whoosh!”

The terrifying force instantly knocked the flying squirrel away, turning it into a cannonball and smashing the remaining buildings on Judicial Island.

Blood spurted out of his mouth uncontrollably in pain.

"Lieutenant General Flying Squirrel!"

Chapter 137 The Strongest in History! Stepping onto the Center of the Ocean Stage!

The flying squirrel smashed through countless Judicial Island buildings and finally crashed heavily into a dilapidated building on the Judicial Island.

The broken building debris flooded the flying squirrel like a torrent.

"Lieutenant General Flying Squirrel!"

Many elite naval personnel cried out in surprise.

These are the absolute elites of the Naval Headquarters, with a rank of at least Colonel.

Under the sweep of Luffy's domineering aura just now, the marines without the rank of colonel in the headquarters were not qualified to step into this battlefield at all.

Flying Squirrel is the core general among the dove generals.

His strength is absolutely top-notch among the lieutenant generals in this department, and his combat power is very close to that of a candidate for general.

He was actually knocked away by the Straw Hat Boy? !

"Ah! What is that?"

The flying squirrel slashed out several sword energies, cutting through the building debris that buried him, his eyes extremely gloomy.

At this time, there were streaks of blood on the corners of the flying squirrel's mouth, and the cloak of justice on his body was also torn. He was no longer as calm as when he faced Luffy just now.

A combination of Armament Haki and the ability of the Rubber Fruit?

wrong!

If it was just a combination of Armament Haki and the ability of the Rubber Fruit, the third gear just now had already reached the extreme.

On this basis, the Straw Hat Boy upgraded his devil fruit ability and armament Haki to a higher level!

Rubber fruit?

What kind of devil fruit is this?! Can even the power of Armament Haki be upgraded a level?

But there was no time for the flying squirrel to think about this problem.

Gear Fourth is the form that Luffy unlocked in advance with the help of Lune after digesting a large amount of desire for liberation.

Because it was just unlocked, the biggest problem is still lack of proficiency, and the physical strength and domineering power are consumed extremely quickly.

Therefore, Luffy must also fight quickly and decisively.

"boom!"

The elastic force continuously generates a powerful reaction force in the air, allowing Luffy to move extremely fast in the air and quickly come above the flying squirrel.

"Rubber rubber!"

Luffy was in the sky, his legs contracting one by one under the elasticity of the Nika rubber, and the armed color domineering that had been integrated into the Nika rubber in his legs also completed a gear upgrade.

"Rhino! Howitzer!"

Luffy roared, and kicked towards the flying squirrel below with his legs at a terrifying speed that was invisible to the naked eye.

"Armed! Iron! Strong!"

The flying squirrel was caught off guard by the fourth gear attack, and its body functions have not yet fully recovered.

Once again, just like how he had just withstood the full force attack from Gear Three, he used his Armament Haki and the strongest iron block to take the full force attack from Gear Four.

"boom!"

"Pfft!"

The strongest iron block was directly broken, and the flying squirrel sprayed out a large amount of blood again.

There was a look of horror in his eyes.

So strong!

The Straw Hat Boy in this state is even stronger than him!

This strength has already made him a candidate for admiral in their Marine Headquarters, as well as a powerful vice-admiral among the Four Emperors Pirate Groups!

With such strength, he can definitely be called a strong man even in this vast ocean.

This kind of strength is simply not something a pirate with 300 million berries can possess!

Utaha Rune's brilliance was so dazzling that the other members of the Straw Hat Pirates seemed to be under the protection of this man.

Even for the Straw Hat Boy, who is the captain, no one on this ocean, including their naval headquarters, pays enough attention to him.

All their attention was drawn to the dazzling brilliance of King Luen.

But only then did the flying squirrel realize that they had underestimated the Straw Hat Boy's terrifying potential!

There is something very wrong with this rubber fruit!

The flying squirrel has been through hundreds of battles and has fought countless powerful people. Although he has not eaten the devil fruit, his understanding of devil fruits is definitely not low.

The abilities of devil fruits are fixed, and no matter who eats them, the corresponding devil fruit abilities will be displayed.

Before awakening, you only need to strengthen your physique to continuously improve the ability of the devil fruit. Before awakening, you will reach a bottleneck and cannot improve any further.

If you want to improve, you can only complete the awakening of the devil fruit. Once awakened, the devil fruit you eat will release all its power and reach the peak of the devil fruit's ability.

No matter who eats this devil fruit, the power exerted by the pure devil fruit ability is fixed.

This is why a top-level devil fruit, such as the top-level natural devil fruit eaten by the three admirals of the Navy Headquarters,

And the Thunder Fruit eaten by the King Rune, relying solely on the power of the devil fruit, can create a top powerful man on the sea.

The reason why those weak devil fruits can only play a supporting role.

The gap between devil fruits is greater than the gap between humans and dogs.

But what about the rubber fruit that Straw Hat Boy ate?

Gear 2, Gear 3, continuously upgrading the power of the devil fruit.

And now the fourth gear, along with the armed color domineering, has been raised to a higher level!

The flying squirrel is very sure that the Straw Hat Boy's devil fruit has not awakened!

But it is actually possible to upgrade the gears?!

This kind of ability is simply not what a parahuman devil fruit should have!

Instead, it looks very much like the multiple transformation points that only animal-type devil fruits have.

And it’s not just an ordinary transformation point, but a transformation point that has upgraded all the original capabilities by one level!

The fourth gear can even upgrade the Armament Haki by one gear.

Such abilities are very close to the characteristics of the mythical beasts in the animal system!

The mythical beast-type devil fruit not only has multiple transformation points of the animal-type devil fruit, but each mythical beast-type can also give the ability user a special ability.

For example, the top-level mythical beast fruit eaten by the Four Emperors, Kaido, the Fish-Fish Fruit - Mythical Beast - Blue Dragon Form,

In addition to giving Kaido the powerful body of a blue dragon, it also gave Kaido the power to control natural elements.

With this power, Kaido is known as the strongest creature in the world!

This ability to upgrade all transformation points by one level, and even to upgrade the armament Haki by one level, is so much like the power possessed by the mythical beast-type devil fruit!

But wasn't the ability of the Parahuman Gum-Gum Fruit that Straw Hat Kid ate?!

Furthermore, his body is very consistent with the characteristics of the superhuman system, and his body has become that of a rubber man.

But from the current abilities of Gear 2, Gear 3, and Gear 4, the power displayed is no longer the power that a parahuman devil fruit should have!

There is definitely a secret behind the ability of the rubber fruit that Straw Hat Boy ate! And it is very likely a huge secret!

The flying squirrel's pupils suddenly shrank at this moment, and an idea emerged in his mind.

Why did the terrible man, Utahn Lun, choose the unknown Straw Hat Pirates?

And before this battle, the Straw Hat Pirates were simply under the protection of this man.

Even if the Straw Hat Boy and the Pirate Hunter have the qualifications of a king,

But in front of a super strong man of Tianwang Luen's level, it is nothing.

Moreover, in the East China Sea, when Tenno Rune joined the Straw Hat Pirates, the Straw Hat Kid and the Pirate Hunter were very mediocre and did not show their current terrifying talents.

With Utaha Rune's terrifying ability to plunder everything, there is absolutely no need for him to join such an unknown pirate group.
