Exhausting Chakra

The scene was momentarily awkward. Rodney's actions had once again enraged Arlong, his eyes turning into bloodthirsty vertical slits, a common occurrence when Fish-Men were provoked.

"My dear comrades have been injured and killed by you, and you dare to humiliate us noble Fish-Men so... human..." He stared at Rodney, meeting his crimson, ominous eyes. "...I will kill you! I'll show you what true cruelty means!! Kuroobi! Hachi! Attack him with me!"

"Mm." Kuroobi adopted the starting stance of Fish-Man Karate.

"Oh, got it." Hachi, the octopus, gripped six long swords with his six arms, Six-Sword Style!

"Are you all preparing to come at me together?" Rodney rotated his still slightly sore and numb arms.

"Water Release: Water Turbulent Wave!"

A long stream of water gushed from Arlong's mouth. Arlong, Kuroobi, and Hachi braced against the flow. Hachi chuckled, "Is this human an idiot? How could water possibly be effective against us Fish-Men?" As he spoke, his six limp octopus tentacles waved constantly, indicating his good mood.

Arlong snorted coldly, "How could a mere human understand the power of Fish-Men!"

"That's not right! Arlong, boss, look at his hands!" Kuroobi noticed Rodney's incessant hand movements and shouted, "Lightning Release: Gratitude Wave!"

Brilliant lightning erupted from Rodney, rapidly surging towards the three Fish-Men.

Crackling!

"Aaaahhhh!" ×3

The three of them were paralyzed by the Gratitude Wave. Rodney stopped spewing water, and while they were still stunned and stiff, he took a deep breath and formed a single hand seal!

His chest swelled, a massive amount of Chakra gathering in his throat. The next second, a sea of flames surged towards the three!

Fire Release: Great Fire Annihilation!

"What?!"

The sea of flames crashed over them, the intense heat scorching their skin.

The moisture on their skin rapidly evaporated, their skin cracking before being consumed by the flames.

Rodney heard several screams and the sound of heavy objects crashing into the water. Understanding what had happened, he stopped outputting Chakra. That single attack had depleted most of his Chakra. Indeed, not everyone is Madara. He used a B-rank Ninjutsu to achieve the effect of a forbidden technique.

However, he had used a considerable amount of Chakra for the visual effect, so the power was naturally impressive.

"I can't let them escape."

"Eight Inner Gates: Gate of Opening! Open!"

Releasing the brain's limitations, allowing him to use 100% of his body's potential.

"Eight Inner Gates: Gate of Healing! Open!"

Releasing the body's fatigue limit, over-exploiting the body's energy to restore stamina, and eliminating the physical exhaustion caused by energy consumption.

"Eight Inner Gates: Gate of Life! Open!"

His skin flushed, and green Chakra energy surged powerfully. This was the last safe zone of the Eight Inner Gates. At this point, Rodney stopped. For the sake of his body, this was just an experiment, not something that should threaten his life.

The shackles within his body temporarily disappeared, followed by the unimpeded flow of Chakra. That was enough.

His foot slammed against the building, and with a boom, the immense force shattered and collapsed the structure. Like a cannonball just fired, he plunged into the water.

Wave Riding Strike!

Before even opening the system, Rodney spotted Arlong in the water, his body charred and severely burned.

Arlong also saw him, his eyes widening. He spoke directly in the water, "Human?! You dare enter the sea! This is our Fish-Men's domain!"

He had noticed that this human's attack method was to spit out all sorts of flashy things, but he wasn't a Devil Fruit user. After all, the guy was moving freely underwater without showing any signs of weakness.

"Wait, Arlong, boss, look at the aura around him." Kuroobi sensed the aura emanating from Rodney, feeling apprehensive. He had also been burned, and the seawater was causing him intense pain, but such minor injuries were commonplace for Fish-Men and nothing to worry about.

The materialized Chakra surrounding Rodney made him hesitant to attack. Who knew what special skills he might unleash next?

However, Rodney wasn't planning on using any special skills. With the boost from a large amount of Chakra, he used the Geppo, which he couldn't normally perform, taking a step in mid-air and flying towards Arlong like an arrow.

Arlong wouldn't bow to humans, nor would he choose to escape. He wanted to defeat Rodney and then tear him apart with his proud teeth. Even if the opponent died, he would never let go!

He opened his mouth wide, biting down on Rodney.

Unfortunately for him, what greeted his teeth was a fierce and unmatched fist. Even in the water, where resistance was high, speed would be compensated as long as the power was great enough.

This punch shattered all the sharp teeth in Arlong's mouth, and Rodney didn't give him a chance to breathe.

One punch after another landed on Arlong's body, as if he were hitting a sandbag!

His right fist pulled back to his waist, a movement that made Kuroobi, who was about to rush forward to support Arlong, widen his eyes.

Fish-Man Karate: 1500 Brick Fist!

Boom!

Immense power exploded, sending Arlong flying out of the water. Rodney didn't linger, breaking the surface and stepping repeatedly on the water, catching up to Arlong. Using Geppo, he leaped into the air, coming behind Arlong and kicking him upwards.

One kick after another, without any intention of stopping.

After countless kicks, he unleashed an aerial shot, kicking him into the ruins of Arlong Park.

Arlong was covered in blood, lying horizontally in the rubble. Without wasting any words, Rodney approached him.

Arlong had already been beaten unconscious. Knowing how troublesome this guy could be, he stepped on his chest, right on the Sun Pirates' symbol, and pressed down!

Crack, crack, crack!

His sternum was crushed by the kick, then collapsed inward, bone fragments piercing Arlong's lungs, heart, and blood vessels. Blood flowed unhesitatingly, rampantly through his body, gushing out of his mouth along with air.

"Arlong-sama!!!"

"Boss!! No!!"

Kuroobi and Hachi climbed ashore, witnessing the scene of Arlong's death.

"You're next!" He fixed his gaze on Kuroobi and Hachi. With these two remaining, the mission would be complete!

"Aaaaaah! I'm going to kill you!" Kuroobi shouted, "Fish-Man Karate · 1000 Brick Fist!"

Rodney easily dodged, his Sharingan once again capturing Kuroobi's movements. As expected, it was just the 100 Brick Fist stance, only with increased power.

He sidestepped, drew a Kunai from his waist pouch, and coated it with a layer of wind.

Puchi!

A thick arm was easily severed. Rodney's movements didn't stop. He stuck an Explosive Tag on Kuroobi's body, spun around, and delivered a spinning kick to Kuroobi's stomach.

"Aaaah!"

Boom boom boom!

A chain reaction of explosions began. Multiplying Explosive Tags killed Kuroobi, the cartilaginous Fish-Man!

"You're next!"

"Y-y-you..." Hachi's hand, gripping his swords, trembled incessantly. He retreated repeatedly. Rodney, like a god of death, left a terrifying shadow in his heart. That godlike and demonic figure inspired even more fear than Arlong.

"If you leave the Arlong Pirates now, I can spare your life. Leave this place immediately and return to your hometown."

Rodney said. The system prompted him that the mission was complete. With only Hachi left, the Arlong Pirates could be considered nonexistent.

Hachi was simple-minded and good-natured. When he wasn't fighting, he was generally quite kind. In the original story, he didn't do anything particularly excessive. He could spare him.

"I... You killed everyone! I won't quit!" Hachi was terrified, but he stood firm.

"Is that so..." Rodney stopped the Eight Inner Gates, then punched Hachi in the face, sending him flying into the sea.

He clapped his hands. After the Eight Inner Gates ended, his body was filled with a sense of emptiness from the loss of power.

The shackles within his body reappeared. He had very little usable Chakra left, feeling extremely uncomfortable, as if he was about to die on the spot.

This wouldn't do. He couldn't fall!

His consciousness began to blur. He forced himself to walk into the forest. Dimly, he saw a river, and a group of Fish-Men he had killed were waving at him kindly.

Is this a hallucination?
