A Fierce Battle Between Brothers

Kizaru stood on a high platform in the distance, hands in his pockets, a lazy smile on his lips as always, but a rare sharpness flashed in his eyes.

His gaze fell upon the now tranquil training area, watching Zoro and Kuina help each other up, their figures bathed in sunlight, a hint of amusement flashing in his eyes.

"That green-haired brat... he's quite the smooth talker!"

"The world of young people is truly dazzling..."

Before he finished speaking, his body had already transformed into countless golden particles of light, Flash and disappearing in the sunlight as if he had never existed.

Training Ground - The Other Side

"Boom--!"

Dust billowed, and flames and shockwaves exploded!

The brotherly battle between Luffy and Ace has reached its most intense climax!

At this moment, Luffy has completely transformed into his humanoid form, which is the form of the Mythical Zoan -type Pink Dragon Fruit.

The pinkish-glowing dragon scales gleamed coldly in the sunlight, its muscles were full and muscular like thunderbolts, its arms were covered in Armament Haki, and its Fist Bone roared like cannons!

He stomped his foot suddenly, and the entire Training Ground shook!

"Fist Bone - Consecutive Breaks!"

"Thump! Thump! Thump--!"

He approached Ace like a storm, each punch carrying immense power, causing the air to shatter layer by layer. Every strike was a burst of power accumulated from his Fist Bone Martial Arts, a perfect blend of Haki and strength!

Ace moved like a fiery shadow, his footwork swift and agile. As he turned, waves of fire rose up, and he seemed to transform into a blazing meteor!

"Flame Line: Piercing the Stars!!"

With a flick of his Right Hand, a super-thin, compressed Flame Line condensed at his fingertips and shot out instantly. It was almost invisible to the naked eye, but the heat wave alone was enough to scorch the air!

"Huh?" Luffy's pupils contracted, and he immediately covered his chest with Pink Dragon to block the attack.

"Ace, that move wasn't very good, was it?" he grinned.

Ace smiled slightly, raised his left hand, and snapped his fingers, "Explode."

"Boom!!"

The barely visible Flame Line touched the center of the Pink Dragon and suddenly exploded and expanded. The high temperature Impact was like the bursting of molten lava from the earth's core, forming a twisted vortex of flames!

"Wow--!"

Caught off guard, Luffy tumbled through the flames, blasted dozens of meters away by the powerful Impact, crashing into the ground and kicking up clouds of dust and debris!

The ground cracked, flames raged, and the air sizzled as it burned!

The naval cadets watching nearby immediately exclaimed in surprise, "How come the flames were invisible at first, but then they just exploded into a ball?!"

"Flames can be compressed and detonated with such precision?! That's terrifying!!"

The smoke and dust had dissipated in the arena.

Inside the crater, Luffy stood up again, his pink scales slightly charred, but a fanatical smile bloomed on his face, his dragon eyes burning with fighting spirit. "Ace!! That move was so cool!! I love it!!"

Ace laughed, flames erupting from his lips. "You idiot Luffy, now you know what 'real combat' means?"

Luffy shook his arms, unleashing the power of the Pink Dragon once more. The dragon scales were covered again, and a giant Pink Dragon phantom appeared behind him!

"Hehe--I'll go for real then!!"

"Fist Bone - Jet Dragon Spear!!"

He suddenly ducked, charged out like Inazuma, his arms straining with high-pressure torque, transforming into a dragon shadow as he pounced straight at them!

Within the Dragon Claw, airflow is compressed, Haki penetrates to the bone, and explosive Martial Arts are infused into every muscle!

Ace's fighting spirit boiled, flames rose like a king of the Battlefield, flames coiled upwards, his whole body was covered by intense Haki and high temperature!

"Flame Ring - Flame Dragon!!"

With a thunderous swing of his flaming arm, a blazing fire dragon roared from his fist, soaring into the sky and colliding instantly with Luffy!

"Boom!!"

Fire dragon and Pink Dragon clash in a furious battle!

Rumble--!

The Pink Dragon and the Flame Dragon collided violently, and the resulting Shockwave Quake-Split the earth, making the entire Training Ground look as if it had experienced a natural disaster!

The two fought fiercely, their fists and claws clashing, sparks flying everywhere!

Dragon roars and raging flames clashed, like two true dragons battling it out in the mortal world!

Flames roared, dragon roars echoed, gales surged, and the ground cracked!

Off the field, Roy stood like a mountain, his hands clasped together, calmly watching the center of the battle.

As the aftershocks of the battle intensified, it became clear that many trainees were struggling to withstand the shockwaves.

He simply raised a finger.

"Whoosh--!"

With a flash of silver light, all the spectators were instantly transported to the safe stands!

"Whoa?! How did I suddenly get here?!"

"It was Vice Admiral Roy?! He just waved his hand and we were all transferred away?!"

"He really is someone who can stand up to two Emperor of the Sea head-on... That's unbelievable!!"

Roy watched the two young figures locked in fierce combat, a faint smile appearing on his lips:

"Ace's control over the compression and explosion of the Flame-Flame Fruit's power has reached the level of 'precise micro-management'."

"And Luffy... his fusion of Fist Bone Martial Arts with the power of mythical beasts is becoming increasingly refined."

Before the dust had even settled, the brothers who had been fighting had already rushed out of the blast center and started a new round of close-quarters combat!

"Fist Bone - Thunderous Collapse!!"

Luffy leaped into the air, raising his right fist high, his Haki gathering between his knuckles, like a cannonball ready to be fired!

With a single punch, the ground instantly collapsed, the air exploded, and a massive vortex of Impact was created!

Ace stepped on a wave of fire, braced himself with his palm against the ground, and leaped into the air!

The flames beneath his feet exploded with a deafening roar, twisting and rising into the air like a fiery serpent, using the explosive force to complete a near-miss, while simultaneously swinging his right arm!

"Flame-Rending Wheel!!"

He covered Haki with high-temperature flames, which condensed into a ring of fire blades. The flames swirled and twisted in the air, incredibly sharp, and slashed straight at Luffy's back!

"Clang--!"

Luffy swung his Pink Dragon tail, Dragon Tail armor blocked the fire wheel with a "crack," but was also pushed Backtrack several meters by the Impact in the next instant!

Before they could even steady themselves, they were already close in!

Every punch landed with a visceral impact, flames mingling with dragon scales! Haki and the resounding crack of muscles filled the air!

Their attacks, speeds, and reactions were all colliding at their limits, and every brush past each other sent sparks and afterimages flying!

"Dragon Bone - Sky Splitter Claw!!"

Luffy roared, his five fingers spread wide, his nails extending into Pink Dragon claws, covered in twisting force and Haki, tearing through space with one claw and fiercely ripping towards Ace!

Ace spun around, his fiery waist tightening!

"Fire Pistol - Explode!!"

He threw a backhand punch, his fist enveloped in spiraling flames, and the punch shot out like a cannonball!

"Boom!!"

A firestorm erupted at the point where the two forces collided. In the gale, the two were forced to separate again, both panting heavily and covered in wounds!

Ace, blood trickling from the corner of his mouth, his eyes burning with fervor, cried out, "Ha... ha... Luffy, you're getting tougher and tougher!!"

Luffy's fists trembled slightly, sweat beaded on his forehead, and he grinned. "You too, Ace... I'm almost catching up with you!"

Ace licked his lips, slowly assuming a fighting stance, the flames in his palm growing increasingly solid. "Then let's try this final move!!"

"Great Flame Commandment - Explosive Flame Lotus!!"

As soon as the words were spoken, the flames suddenly contracted violently!

A lotus flower, forcibly compressed from high-temperature flames, bloomed in Ace's palm. The central fire core twisted and pulsed, releasing heat that even caused the air to hiss and the space itself to tremble slightly!

Under the scorching heat, the ground began to melt, and the red light emitted by the fire lotus was like the sun falling to earth, with an overwhelming sense of oppression!

On the other side, Luffy took a deep breath, his Fist Bone tucked to his waist, and the torque and Haki were continuously compressed, his bones making a low "crackling" sound, and dragon-shaped aura patterns extended wildly along his arms!

"Fist Bone-- "

"Galaxy Impact!!"

A punch, brimming with violent compression, flashed with Cross-shaped Star, like a collapsing star core. Its Haki trembled and twisted, causing the ground to crack and collapse around it, with layers of wind pressure exploding like the first explosion of the Milky Way!

"!!!"

Roy, who was standing on the sidelines, suddenly narrowed his eyes, which had been calm as still water, and raised his eyebrows in a rare manner, revealing a look of shock.

"This method of accumulating and compressing power... is actually..."

"Galaxy Impact?!"

He looked at Luffy in the arena with a hint of disbelief, his eyes filled with a complex and shocked light.

"Although it's just a miniature version... it already has a certain look!"

"Luffy's learning speed... it's just insanely fast."

Ace and Luffy roared simultaneously, and two blazing energy cores erupted in their hands!

On one side is a high-temperature compressed flame, compressed like a lotus flower in the palm of one's hand, almost Sky Splitter;

On one side is the Explosive Meteor Fist, a fusion of Haki, the power of the Pink Dragon, and Fist Bone Martial Arts!

Just as the two forces were about to collide head-on—

Roy, standing on the sidelines, suddenly sharpened his gaze!

"If this energy were released entirely on the ground, the entire Training Ground would probably be blown to smithereens!!"

Roy suddenly raised his Right Hand, his eyes narrowed, and his Haki and Devil Fruit power activated instantly!

As the silver light spread, a spatial rift rapidly opened above the point of impact between the two, and the next instant—

"Boom--!"

Just before the explosion, most of the entire epicenter was forcibly pulled away from its original position, and the entire space was instantly transferred to the clouds thousands of meters above the Marine Headquarters!

Moments later, a deafening explosion rocked the sky!

"Knock knock!!--"

High in the sky, a huge, lotus-shaped explosion burst forth like the sun, and the Shockwave formed a rolling cloud that spread throughout the entire sky above Marineford!

Flames and Galaxy Impacts clashed in the air, illuminating the entire sky above Marine Headquarters!

The entire navy came to an instant halt; the soldiers, officers, and cadets, gazing up at the sky, were all in shock.

"Wha... what the hell?! The sky exploded?!?"

"Was it... was it Luffy and Ace who fought?! That was their ultimate punch?!"

"Damn it! The sky's cracked open!!"

Meanwhile, in the Fleet Admiral's Office

"Boom!!"

A loud bang shook the office windows, and a cloud of dust fell from the ceiling!

Sengoku abruptly stood up, slammed his hand on the table, Fire Charge, "Garp!! Do your two bastards want to dismantle Marine Headquarters?!"

"You just sit here eating Senbei and watch them set off fireworks overhead?!"

On the sofa, Garp was happily munching on Senbei) when he heard the noise and burst into laughter. "Wahahaha!!"

"That move?! That kid actually learned the Galaxy Impact?!"

"He truly is my grandson!! He's got about 30% of my youthful charm!!"

Sengoku's veins throbbed. "Thirty percent?! If he grows a few more years, won't he be able to destroy the Red Line?!"

Garp continued munching on his Senbei, looking relaxed. "Don't be angry, Roy's here anyway~ Young people should be more passionate!"

After the bullseye was removed from the arena, the dust settled moments later.

Luffy knelt on the ground, his right arm giving way, and blood trickling from the corner of his mouth.

Ace barely managed to stay upright, looking disheveled, his flames nearly extinguished, but he eventually managed to stand.

This fierce battle--

Ace wins by a narrow margin!

Ace staggered to Luffy's kneeling Luffy, a smile playing on his lips, and extended his hand. "Silly little brother, you've worked hard."

Luffy was stunned for a moment, then grinned and grabbed his brother's hand, and was pulled up!

"Haha! I almost won!!"

"Keep dreaming!" Ace laughed wildly.

"You're becoming more and more like a monster."

"Hehehe... I'm your younger brother!!"

The two brothers smiled broadly as they stood side by side in the devastated Training Ground.

The flames and dragon shadows faded, but the bond between brothers burned ever brighter in the firelight.

On the Spectator Stand, the students were in high spirits and extremely excited!

"They're so cool... They're the ones we should be chasing!!"

I want to become stronger too!

"Captain Ace!! Luffy!!"

Off the field, Zephyr slowly lowered his hands, his gaze deep and his voice low. "The two of them, one possesses the 'Sunfire,' and the other possesses the 'Dragon's Will.'"

"This is the spark of New Era."

Roy, standing on the edge of the platform, watched all this quietly, his expression revealing his satisfaction.

Burn!

Let's carve out your 'future' inch by inch.
