One Piece: The user of the Nen-Nen Fruit, who overturned the sea.

Roy and Hawkeye, who were closing in from the front, never expected this.

The Golden Lion was willing to abandon its defenses and pour all its power and will into the two of them in a desperate gamble!

"That madman!"

Facing the terrifying, all-encompassing final strike coming straight at him, Roy's pupils constricted sharply, and the red light in his eyes flickered incessantly.

A deathly warning is coming on fast!

"Mihawk! Retreat!"

Roy roared and, almost at the same time he spoke, shoved Hawkeye hard with his left hand!

"Shinra Tensei!"

An impact force struck Hawkeye beside him, pushing him violently to the side and backward, escaping the core attack range of the slash!

At the same time, he gripped the "Red Rock" blade, which was already wrapped in Conqueror's Haki, and poured all his Haki, Devil Fruit ability, and swordsmanship into the blade without reservation!

"Aaaaaaah!! Block it!!!"

Roy let out a roar that surpassed his limits, and facing the earth-shattering golden slash, he fiercely unleashed his strongest strike to date!

The black and red Conqueror's Haki lightning was more solid than ever before, as if it had transformed into a tangible flame burning on the blade!

"Buzz!"

In the instant he swung his sword, Roy felt as if the whole world had slowed down.

The trajectory of the 'Red Rock' in his hand as it sliced ​​through the air was clearer than ever before!

A sudden realization dawned on me—swordsmanship is not just about strength, but the ultimate fusion of will and skill!

The 'Red Rock' in his hand emitted a crisp hum, as if celebrating some kind of transformation!

Roy's swordsmanship, under the immense pressure of this life-or-death situation, finally broke through its final shackles and entered a completely new realm—the Great Swordsman!

"boom--------!!!!!"

The strike, imbued with all of Roy's power and will, collided violently with the Golden Lion's terrifying final strike!

A light more dazzling than ever before erupted, instantly engulfing Roy's figure!

The deafening roar seemed to shake the entire Thunder Island!

The terrifying shockwave spread wildly forward in a fan shape, lifting the ground layer by layer, and smoke and debris swept outward like a tsunami!

Hawkeye, who had been pushed aside, steadied himself and stared intently at the center of the explosion. Even he, who was usually calm, couldn't help but feel a hint of worry.

Barrett and Tezzolo held their breath, staring nervously ahead.

The light slowly faded away.

Roy remained standing in place, still holding the knife in a forward-slashing posture with both hands.

But the ground beneath his feet had completely vanished, forming a huge fan-shaped depression. His clothes were tattered, and the webs between his hands, holding the knife, were completely torn open.

Blood flowed continuously down the blade of "Red Rock," dripping onto the scorched ground.

"puff!"

Roy coughed up a mouthful of blood, his face turned pale, and his body swayed. He could only use the "Red Rock" to firmly insert itself into the ground to support his body.

Although he managed to withstand the fatal final strike thanks to his breakthrough in the heat of battle and his mastery of the great swordsmanship,

However, the terrifying recoil and the destructive intent contained in the strike still caused him serious damage.

"Roy/Boss!"

Hawkeye flashed and instantly appeared beside him, supporting his body.

Barrett and Tezzolo immediately surrounded them.

"Cough cough... I'm... I'm not dead yet..."

Roy struggled to speak, "Golden Lion...he..."

Roy's words came to an abrupt halt.

"Cough...cough cough...heh...hahahaha!!!"

Accompanied by a violent cough and maniacal laughter, a golden figure swayed and floated up from the deep pit.

His appearance was even more wretched than Roy's; there was hardly a single unscathed spot on his body.

The flowing blood stained him into a blood-soaked figure, and upon closer inspection, fragments of his internal organs could be seen on his clothes.

His breathing was visibly weakening!

But! The madness in the Golden Lion's eyes burned even more intensely!

"Heh... Hahaha!"

"Kid... I acknowledge you!"

"As expected!" Roy understood. With the physiques of these top-tier monsters in the pirate world, it would be impossible to determine a winner without fighting for several days and nights until their stamina was completely exhausted.

"war!"

Roy mustered his strength, suppressed his surging blood and qi, and raised "Red Rock" once more.

Hawkeye silently gripped the black blade, Barrett let out a furious roar of resentment, and Tesoro's body crackled with electricity once more.

The battle has broken out again!

This time, it's no longer a clash of skill and strength, but a test of will and stamina!

From the blazing sun to the changing of the stars and moon... the battle on Thunder Island continued for another full day.

The roaring sound that came from it was no longer as deafening as it had been at the beginning.

Instead, there was only a dull panting and the sound of fighting.

Roy felt as if his arms were filled with lead, and every swing of "Red Rock" brought him excruciating pain that felt like his whole body was being torn apart.

Only through the exquisite control over his body gained from breaking through to the level of a Great Swordsman was he able to maintain his movements without deforming, and to block and deflect the Golden Lion's attacks, which had also become slower but were still deadly.

Hawkeye's Black Blade Night was still precise, but the speed and power of his strikes were not what they used to be. His breathing was heavy, and the web of his right hand holding the blade was already a bloody mess.

Barrett's roar grew hoarse, and his massive body was covered in a crisscross of wounds.

No longer using wide-range techniques, relying on instinct and the most basic Armament Haki, he uses his body to withstand attacks and his fists to smash things, like a tireless fighting machine.

Tesoro had already exhausted his strength half a day ago, and was now lying in a place far away from the battlefield, silently recovering his strength.

Shiki the Golden Lion was in even worse condition.

His kimono was already stained red with blood, and his breath was so weak that it seemed he might die at any moment. His attacks had long since lost their rhythm, and he was fighting solely out of an indomitable will and fighting instinct.

Both sides are overdrawing their life force, competing to see who will fall first!

"Bang!" Barrett punched the Golden Lion's arm as he blocked, and the two of them staggered backward at the same time.

"Clang!" Hawkeye slashed away the attack aimed at Roy with his sword, and his own arm went numb from the impact.

Roy seized the opportunity to thrust his knife, but Golden Lion barely managed to dodge and only managed to slash his ribs.

The battle has reached a brutal and desperate stalemate, now it all comes down to who runs out of stamina first.

But just then, a bold voice boomed from the horizon.

"Hahahaha! Shiki! And those brats over there causing trouble! Stop it, all of you!"

The voice was like a resounding bell, instantly bringing both sides, who were blinded by rage, to their senses.

Marine hero, Monkey D. Garp!

Both sides, locked in a fierce battle, felt a chill run down their spines simultaneously!

They exchanged a glance, immediately stopped what they were doing, and looked at the distant sea!
