The pirates sat and forgot, and they really believed the nine truths and one lie.

Nika's big head briefly suppressed the navy hero. Seeing this, the navy behind Garp strode forward to help.

Nika Luffy's big head was still giggling, and Garp's shaky figure was reflected in his huge pupils.

Suddenly, two black shadows tore through the air. The mechanical prosthesis on Zephyr's left arm glowed with a faint blue electric light, and Sora's Navy Justice Cloak fluttered. The two appeared on both sides of Luffy almost at the same time.

"Armament Haki·Hardening"!

The dull sound of collision shattered the clouds, and two ink-black fists accurately hit Luffy's left and right eye sockets.

The rubber eyeball was instantly compressed into a strange flat shape, and the armed color domineering penetrated into the skull like a maggot in the tarsal bone, trying to forcibly disperse the chaotic life force.

"Whoa-!"

Nika's form howled in pain for the first time, and the dozens-meter-tall giant head was hit by the huge force of the meteorite, flying away with a spiral air wave.

Huge gaps were created on the path along the way, and some unlucky people who couldn't dodge in time, including navy and pirates, were knocked out and knocked unconscious, losing their combat effectiveness.

Karp half-knelt on the ground, leaning on his sore fists, feeling the familiar breath of his two old comrades, his cloudy eyes filled with gratitude.

"I never thought that one day the three of us old men would be fighting side by side, and the enemy we were going to deal with would be my grandson," Karp couldn't help but laugh at himself.

Zephyr's mechanical arm was emitting sparks. It was a temporary installation for him by Caesar Courant, giving the former admiral a certain amount of combat power.

Most of Kong's uniform had been shattered, revealing his bronze chest covered with battle scars. Before becoming the Navy Admiral, he was also a battle-hardened naval soldier.

Zefa's expression was not optimistic, and he explained the reason: "The front end of my arm, including two fingers made of seastone, successfully touched Nika's body, but did not restore him to his original state."

Caesar Clown gave Zephyr a secret weapon. The other three fingers of the mechanical arm can include Armament Haki, while the other two fingers, although inconvenient to move, are made of seastone and cannot include Armament Haki.

Seastone is the nemesis of devil fruits, so the punch that Zephyr just threw was more crucial than the punch that Cyborg Kong threw.

"What exactly is Nika? Can it still be defined as a devil fruit?"

Steel Bone Sora didn't expect this change to happen. Originally, the three old guys were going to support the navy admirals in the battle, but now they have to deal with Nika.

The battle between the Navy Admirals and Whitebeard's allies is still going on, and they are temporarily unable to intervene in the battle involving Nika.

Admiral Kizaru faced Marco. This slacking admiral still showed his previous level, and the battle with Marco was at the stage of minor skirmishes.

Occasionally, he would fire a few lasers to penetrate the Phoenix's vital parts, knowing full well that the result would be the same and that he would not be able to cause any harm to Marco.

Admiral Aokiji faced Mirajane. Mirajane's devil fruit ability was too special, and the strength of her domineering power was not inferior to that of the older generation. Kuzan's proud freezing ability could only temporarily trap the female demon and could not control her for a long time.

Kuzan and Mirajane fought back and forth, avoiding close combat. Kuzan knew that this was his disadvantage, so he just kept restricting Mirajane's movements and was temporarily held back.

When Green Bull faced Gajeel, the roots created by the Mori-Mori Fruit could not break through the iron dragon's iron defense in a short time, and could not absorb and convert the energy in Gajeel's body.

Gajeel has become nature's lumberjack, madly destroying visible plants and chasing after Aramaki. Admiral Green Bull is the admiral with the weakest actual performance ability, and he has no way to deal with the thick-skinned guy.

Admiral Akainu and Whitebeard have not fought yet. As core members of the two forces on the field, they are wary of each other while paying attention to Nika's condition.

"Isn't Nika afraid of seastone?"

Sakaski, who was watching the battle, had a question. Due to the repeated urging of the Molten Murgais in his body, his senses were greatly enhanced while gaining strength.

After being hit by the fist carrying seastone, the power of Nika only weakened Luffy for a very short time, so short that the three old seniors had no chance to throw a second punch.

Admiral Akainu asked the devil in his heart, "Since you said Nika is a devil, the devil should know the devil best. Do sea water and seastone have an inhibitory effect on devils?"

Unexpectedly, the voice inside the body answered directly without any hesitation, "It is restricted by the rules of this world and has a certain impact, but it does not mean that it can be the key to victory."

Molten Man Murges' words were soon confirmed. Nika Luffy returned to his normal size and walked out of the smoke and dust laughing.

With a pair of black panda eyes, if it were an ordinary person, the punch from Kong and Zephyr would have blown his head off long ago.

"Uncle, you are so bad! You actually put seastone on your arm." Luffy had an angry expression on his face and jumped happily on the spot, expressing his dissatisfaction with his lively personality.

A normal Devil Fruit user, if exposed to a trace of Seastone, will immediately lose their combat power, and their physical strength will take time to recover.

As long as Nika Luffy is out of touch with the seastone, his condition will quickly recover. He is simply a monster among monsters. Admiral Kizaru and Marco are playing in the air, and they keep shouting that Luffy is a monster.

Zephyr and Sora's arms were placed on Garp's shoulders at the same time. The three old guys fought side by side on the battlefield, and this long-lost comradeship came into being.

"Let me help you teach your grandson a lesson. He is a devil fruit user, and seastone is his nemesis." Zefa moved his mechanical arm. Caesar Kulang also left him a lot of small surprises, which he would use to deal with Nika.

"Control him and put seastone handcuffs on him. We'll talk about the rest later." Gang Gukong took out the seastone handcuffs from his arms and put them on Nika. All problems could be solved.

"Okay, the three of us will work together to let my good grandson experience the fists of our elders." Garp moved his sore wrist and agreed with the fighting methods of his two comrades.

Although it was shameful for three old guys to bully a young man, the three of them had eaten more salt than Luffy had eaten meat, and had more combat experience.

As for whether they would feel ashamed of this, the three old men were almost three hundred years old in total, and they were bullying a kid who was not even twenty years old. Garp, Zephyr, and Cyborg Kong didn't care about their reputation.

"You can't do this, is it right for you to bully me alone?"

When Nika Luffy saw this scene, he showed an extremely funny and terrified expression, but only Luffy himself knew how much fear was in his heart.

Luffy is still isolated and helpless now. Other pirates can't help him. Sabo can't get away in a short time. He can only deal with three veteran navy pirates alone.
