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

Luffy's first appearance in Nika form shocked the navy present, but the senior officers gradually regained their composure and began to deploy how to deal with the Straw Hat Boy.

"Are you still Luffy?"

Garp's old face was frighteningly gloomy. He could not sense the familiar aura of his grandson, but was instead replaced by a more different aura, neither human nor god.

"Grandpa, why don't you smile?"

Nika Luffy made faces at his grandfather, using the elasticity of his rubber ability to the extreme, causing his head and eyes to grow and shrink.

Adults with normal physiological cognition will find Luffy in Nika state very strange. He may only be popular among children.

"No matter who you are, I will beat you out of my grandson's body." Garp was obviously really angry this time. Deep down in his heart, he did not admit that the pure white man in front of him was his own grandson.

Tianmu mentioned that the devil fruit could have the potential to possess other bodies, but Garp just didn't say it explicitly. He suspected that his grandson had been possessed by Nika, and the person in front of him was just Nika who inherited Luffy's memories!

"Hahaha Grandpa, you look old and ugly now, please smile!"

"Shut up"!!!

Garp's figure was almost in the state of domineering domineering, and the moment he swept the entire scene, he crossed the space and appeared in front of Nika Luffy.

The iron fist that had shattered steel countless times was now surrounded by a dark red violent airflow, shredding the atmosphere with a sharp roar.

The fist turned into a black meteor and hit Luffy's face heavily before his pupils could catch the trajectory.

boom! !

This punch even created a sonic boom. The force tore through the air, causing the Marines watching the battle around to stop breathing, as if their souls were trembling.

The expected crisp sound of bones breaking did not happen. Instead, the muffled thunder of the iron fist mixed with the domineering color exploded, and Luffy's entire facial contour was concave inward like clay crushed by a huge rock.

The rubber skin showed strange wrinkles under the extreme strength, and Luffy flew backwards like a kite with a broken string, crashing into a group of pirates not far away.

"No, my domineering aura didn't cancel it out. Is that Nika's ability?"

Garp stood there with some doubt. The full-strength attack he had just delivered to his grandson did hit the face, but why did it feel wrong? Didn't he touch the bone?

The pirates of Whitebeard's pirate group didn't care about Luffy who was beaten and sent flying. Instead, they dug Luffy out from the crowd.

"Brother Ace, are you okay?"

"Ah! Your face..."

When Luffy was dug out from the crowd, his entire face was sunken, like a concave meat bowl. If it were a normal person with a deformed head, he would have died a hundred times already.

Nika Luffy's clothes were only slightly dirty, and not a drop of blood came out. "Grandpa's fists are so powerful, I almost got killed"!

Nika Luffy's head began to inflate, and his sunken face slowly began to recover. After a few seconds, he laughed in front of everyone again, completely unconcerned about the fatal injury.

The pirates didn't expect that Ace's younger brother would be so tough. After jumping and saying goodbye to everyone, he returned to his own battlefield and faced his grandfather who was looking stunned.

"Haha... Grandpa, are you going to kill me? You are so bad and must be punished." Nika Luffy looked angrily, puffing himself up like a ball, bouncing up and down in Garp's eyes.

The navy was shocked by Nika's incredible recovery ability. The navy hero didn't hold back at all when he threw that punch just now!

Even if Nika couldn't be killed with one punch, he would at least be unconscious for a while. Luffy in front of him looked like nothing had happened and still maintained a perfect form. Nika's threat factor was even greater than expected.

"Stop talking nonsense. Since you can take a beating, then take a few more punches from me." While Garp's left and right fists were covered with Armament Haki, they were also wrapped with a layer of Conqueror Haki. With the blessing of the two colors of Haki, he didn't believe that he couldn't break Nika's defense.

"What a scary grandpa, who can save me... Ace, look, grandpa is so scary"!

Every punch from Garp's iron fist hit Luffy with a sharp sound that tore through the air. The domineering aura was like an invisible pressure, which made the spectators unable to move. The dense fist shadows fell on Luffy like a storm.

Luffy in Nika form was shaken violently by the continuous blows, and a terrible dent was smashed into his rubber-like body.

His chest almost collapsed to his spine, and the cry of pain that escaped his throat was blocked by the impact of the next punch.

The outline of Garp's fist could even be clearly seen in the concave part, but the next second, Luffy's body would suddenly rebound and return to its original shape, as if the devastating attack had never happened.

Garp's eyes became more serious and his attack became more fierce. The domineering aura made the air around him tremble, and the hardened armament aura made his fists shine with a metallic luster.

But no matter how he attacked, Luffy's body always bounced back with amazing resilience, and there was even a happy smile on his face, as if he was enjoying this ultimate battle.

"Grandpa's fist... still hurts so much..." Luffy grimaced in pain, his expression as weird as it could be.

From beginning to end, it was Garp who was beating Luffy one-sidedly. Nika stood there motionless and did not fight back for several minutes.

There was pain feedback when Luffy was hit, and the Haki did cause damage to Nika, and the inhibitory effect of the Conqueror's Haki on the Devil Fruit was still there.

But Luffy couldn't resist the cloud of fire behind him, which kept emitting white steam and repairing Nika's injuries, and the speed of repair was getting faster and faster.

Garp could even feel that he kept beating Nika, as if he was adding layers of strength to Nika. Nika's momentum was getting stronger instead of increasing!

The old bones of the navy hero punched out with his fists, leaving afterimages. He took care of Nika Luffy's whole body, and every part of his body was beaten by his grandfather. He threw at least hundreds of punches in a few minutes.

Using Haki requires continuous consumption of physical strength. After all, Garp is an old man, and his physical strength recovery speed is not as strong as when he was young. His punching speed began to decline, and there were serious problems with physical strength continuity.

The navy watching the battle were all shocked at Nika's recovery ability. He was beaten hundreds of times by the navy hero, but he stood there and took the beating as if nothing had happened. He is truly a filial grandson.

"Haha... Grandpa, are you tired? Why is your punch speed decreasing?"

Luffy's caring words were extremely harsh to Garp, and Nika's sarcasm made the navy hero's eyes bloodshot.

Seeing this familiar scene, the sensible grassroots navy gave up fighting with the pirates and began to retreat frantically, away from the area where the grandfather and grandson were fighting.

Garp's reputation for fighting with his fists won't be easily defeated by Nika.
