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

Since he couldn't find the candle man, Luffy simply gave up the search for the time being. The three old guys standing in front of him, including his grandfather, had to be dealt with without mercy.

"If Luffy can arrest you the first time, he will do it a second time. If we let you rescue Ace, where will we old guys put our dignity?"

Zefa's mechanical arm shone with a cold metallic luster in the sunlight. It was raised without warning, and the muzzle suddenly spewed out a dazzling flame.

Nika Luffy's pupils shrank, and the numbness from being hit by the seastone bullet last time seemed to still linger in his limbs.

He didn't dare to delay for a moment. He suddenly tapped his toes in the air and his body twisted and turned in the air like willow catkins.

shhhhhh!

The metal bullets and seastone bullets made a sound of breaking through the air, leaving deadly silver lines in the sky, closely following Luffy's figure.

"Are you my grandfather's friend? You are such a bad senior. I will let Usopp teach you a lesson next time."

Luffy knew very well how powerful the enemy was and didn't dare to even think of taking it head-on. He used the rubber's flexibility to the extreme and narrowly avoided each deadly bullet.

Luffy made several incredibly difficult evasive moves in the air, all of which were just right, barely avoiding the fatal attack.

Zefa had a blank expression on his face, and the muzzle of the mechanical arm kept changing its angle. The dense rain of bullets was like a big net of death, compressing Luffy's body.

The old men were waiting for this opportunity. The air suddenly tore apart, and two afterimages leaped up from the ground accompanied by a barrage of bullets.

The knuckles of Kong Ganggu's fist shone with a black metallic luster, and the wind from his fist, carrying the shock wave of the Six Styles Secret Art, blasted towards the Straw Hat Boy's temple.

Garp's iron fist was wrapped with materialized domineering aura, and the old cloak of justice fluttered in the airflow, determined to break the spine of this grandson who repeatedly disrupted the order of the navy.

Two pitch-black fists in armament color hit Luffy at the same time, but the result disappointed everyone. The navy watching the battle did not hear the sound of bones breaking.

Luffy didn't even let out a scream, because the fists of the two old heroes had clearly hit Nika's vital points accurately!

"It's so scary, I almost got seriously injured by you again"!

The punches thrown by Cyborg Kong and Garp encountered the same problem. The two old guys felt like they were punching a bouncy ball, and the elasticity of the rubber was fully utilized at this moment.

"Is this the ability of the mythical beast species?"

Sora hit Luffy's head so hard that it made a dent, but didn't hurt any bones. Luffy's skull had changed and was twisted and deformed like rubber.

Garp's punch hit Luffy's chest so hard that it bulged forward. The grandfather did not touch his grandson's spine. The rubber man's ability to withstand blows was fully demonstrated at this moment.

"You've had enough fun, now it's my turn"

Nika Luffy's arms suddenly turned into two white afterimages, stretching out rapidly as if they had life, and accurately wrapped around Garp and Sora, who were closest to him.

The pupils of the two legendary warriors suddenly shrank. Just as they were about to break free, they felt an irresistible force coming from their bodies and were tied up like dumplings by Luffy's arms.

Luffy grinned, and his body instantly turned into a high-speed spinning top. This was his new move, the "Big White Beyblade"!

The strong wind generated by the rotation in the air blew the gravel on the ground into the sky. Garp and Cyborg were firmly bound in the center of the rotation and could not perform any moves at all. The two old men were dizzy.

The gyroscope in the air spun upside down, and they could only watch the ground rapidly enlarge in their field of vision. The next second, the three of them crashed heavily into the ground with their heads down.

boom! ! !

A deafening roar was heard, and a huge deep pit was instantly knocked out on the ground. Smoke and dust rose into the sky like a volcanic eruption, covering the surrounding environment.

The powerful shock wave spread in all directions, shaking the nearby navy and pirates.

In the deep pit, Garp and Cyborg felt dizzy, with a trace of blood flowing from the corners of their mouths. It was obvious that they had suffered a considerable impact and had symptoms of mild concussion.

Luffy, on the other hand, used the inertia of the rotation to stand steadily at the edge of the pit, still with that relaxed smile on his face, and kept saying several times, "It's fun, really fun."

Gang Gukong was older and weaker, and his body was planted upside down in the ground. Due to the influence of gravity, all the blood in his body gathered in his head, making it impossible for the old marshal to pull his head out of the ground for a while.

Garp was also pinned to the ground by his own grandson. After a minute, he regained consciousness and punched the stone that was stuck in his head, and the navy hero was finally free.

"Luffy has no mercy on your grandfather. You little brat, I really raised you in vain." Garp noticed that Cyborg's head was stuck and he couldn't free himself, so he went to save his companions as soon as possible.

Garp was trying to pull the old marshal's head out of the ground carefully, just like pulling a carrot. Luffy laughed happily when he saw this scene.

Luffy was very angry when he found that the purple-haired old man was loading ammunition, "Why don't you laugh? Wasn't what happened just now funny? Look at you frowning. Let me help you cheer up!"

The gears of the mechanical arm made a harsh gnashing sound, and the last seastone bullet was accurately loaded into the muzzle. Zefa was going to use it to respond.

Just as the muzzle fire reflected in his pupils, a ball of scarlet suddenly exploded at the edge of his vision. Zefa thought he could delay time.

"Too slow!"

The boy's voice exploded like a thunder in his ears. Zefa only saw a fist wrapped in a white wrist guard breaking through the air.

The gusts of air created by the fists actually tore a hole in the surrounding smoke and dust, and the sound of metal groaning under the heavy burden could be heard.

Luffy's fist went straight through the robotic arm, causing dazzling sparks to explode at the joints. Broken gears flew like a rainstorm, and Caesar Clown's technological product was instantly scrapped.

It wasn't just the robotic arm that was shattered. Zefa felt an irresistible force exploding through his chest, and the crisp sound of broken ribs was drowned out by the duller sound of the impact.

He flew backwards like a puppet with its strings cut, and behind him was the brick and stone wall of the naval building, which rapidly enlarged in his field of vision.

In severe pain, he saw himself crashing through three layers of stone walls. The blood foam coughed up by Zefa drew a sad arc in the air, and was sent away by Nika with a punch, temporarily leaving the stage.

This punch was too powerful. Nika Luffy did not hold back his strength. It was purely a numerical crush in terms of strength. At the critical moment, he even stopped the supply of martial arts energy.

If this was not done, the scene would have been very bloody. Luffy's light punch would have pierced Zephyr's chest on the spot, and it would not have been as simple as damaging his internal organs.

Without the restrictions of seastone, Luffy can finally roll up his arms and fight with confidence.

The navy immediately dispatched personnel to rescue Zefa in the direction of his landing point. The former admiral could not die easily.

Nika would never have thought that his punch would shatter the last sanity of the Night Demon.
