Dragon Legacy

Marineford Navy Training Ground

Under the blazing sun, smoke billowed across the Training Ground, and the air was thick with the mingled scents of sweat and an aura of Haki.

"Gum-Gum Pistol!!"

Luffy suddenly stretched backward, his Armament Haki swirling around him, and slammed into Garp's chest with a whistling sound!

"Bang!!"

Both palms slammed solidly into Garp, producing a dull thud.

But Garp stood like an iron tower nailed to the ground, not even the hem of his clothes swaying.

He grinned, revealing a proud smile that covered his wrinkled face, "My strength has indeed improved a bit since last month... but still, I'm too green!!"

"Damn it!! How come Grandpa's chest is harder than Warship?!" Luffy, his face flushed red, swung his arms and stomped his feet in anger.

"Ha ha!!"

Garp laughed so hard he almost fell over, then the next second he swung a heavy punch at Luffy's head. "Because I am 'Iron Fist' Garp!!"

"Whoa--!"

Luffy was slammed into the ground like a spring, his legs trembling weakly as he groaned and complained, "Violent old man..."

Not far away, Ace and Zoro were also engaged in a fierce battle in an open space.

"Cross Fire!!"

Scalding flames erupted from Ace's palm, sweeping out in an X-shape!

Zoro's expression hardened, and he drew both swords simultaneously, Armament Haki coating the blades as he cleaved through the flames!

"Two-Sword Style: Tiger Hunt!!"

One slash cut through the flames, another aimed at Ace, but Ace was already close enough that a scorching spinning kick whipped towards Zoro's side!

"Bang!!"

Zoro drew his sword to defend, and the two were simultaneously knocked back, their footsteps leaving deep scratches on the ground. They were breathing heavily and sweating profusely.

"Not bad, Moss Head!" Ace grinned, flames dancing on his fingers.

"Hmph, you're not bad either." Zoro replied coldly, but a fierce smile appeared on his lips.

Just then, a familiar, lazy voice came from the Training Ground: "Hey, it's getting lively here."

Everyone turned around and saw a figure that had appeared at the sidelines at some point.

A black cloak fluttered in the wind; hands in pockets, a smile playing on his lips.

"Brother Roy!" Zoro immediately sheathed his sword and stood up straight, his expression respectful.

"Where have you been hanging out lately?" Ace, arms crossed, unconvinced. "You've been gone for so many days, you didn't sneak off to some Island for hot springs again, did you?"

"Huh? Soaking in a hot spring? Stop talking nonsense, you brat."

Roy approached and punched Ace in the head with a backhand.

"I'm a dignified Marine Vice Admiral, I'm very busy with official duties, don't you understand?"

"Ugh!" Ace muttered, rubbing his head, "Grandpa Garp must have a lot of free time..."

Garp, who had just finished beating Luffy, widened his eyes instantly upon hearing this. "Kid, you want to do extra training too, huh?!"

Ace immediately shrank back, hiding behind Roy: "No, no, old man, I was wrong..."

Roy shook his head helplessly, then his gaze sharpened, his smile vanished, and his expression turned serious.

"Grandpa, there's something important that requires you and Luffy to come alone."

Garp's expression changed slightly, sensing the unusual tone in his voice, and he nodded in a deep voice. "Understood."

He picked up Luffy, who had just struggled out of the ground and was looking completely bewildered, and gently patted the back of his head. "Let's go, kid."

"Hey? Where are you going? I haven't gotten my revenge yet!"

"Shut up and listen to me!"

"Whoosh!"

The space rippled, and Roy waved his hand, causing the three to vanish from the Training Ground in an instant, leaving behind only a pile of dust and a bewildered Zoro and Ace.

"Where did they go?" Zoro frowned.

Ace crossed his arms and pondered, "Could it be another secret mission...?"

The Training Ground returned to calm, with only the distant sea breeze and the sound of Warships ' horns echoing through the air.

Marineford - Back Mountain Secret Training Ground

The setting sun burned across the sky like flames, its golden afterglow spreading across the cliff tops, while the sea breeze, accompanied by the sound of waves, swept in from afar.

"Whoosh--!"

Ripples spread through the air as Roy, along with Garp and Luffy, instantly appeared in a secluded Training Ground on the Rear Mountain.

"Whoa--! Where am I?!" Luffy, who had just been pulled out of the ground by Garp, was dizzy from being spun around and fell to the ground, rubbing his head and looking around.

Looking around, this was Zeng Garp's secret Training Ground, and the sound of waves crashing against the cliffs could be heard in the distance.

Garp glanced around at the familiar surroundings, his expression serious. "Kid, you didn't come here just for a chat, did you?"

Roy did not respond immediately, but instead solemnly took out a specially made Lead Box from his pocket.

With a light tap of his hand, the mechanism activated, and the lid slowly opened.

A Devil Fruit, radiating a soft pink glow, lay quietly inside.

The patterns on the fruit's surface resembled fine dragon scales, subtly revealing an extraordinary aura.

"This is..." Garp's pupils contracted sharply, and a rare look of shock appeared on his face, "Devil Fruit?"

"That's right," Roy said calmly. "The result of Vegapunk's twenty years of research, the Artificial Fish-Fish Fruit, Mythical Zoan, Azure Dragon Form (pink version), refined from Kaido's Lineage Factors."

Upon hearing this, Garp's expression darkened slightly, his breathing became heavy, and his eyes, fixed on the fruit, revealed apprehension. "You brat... you dare to touch something so dangerous?"

As a legendary Marine who had fought Kaido times, he knew all too well the terror of the Azure Dragon Form —its Dragon Breath that could tear the sky apart, its impenetrable scales, and its agility to soar through the heavens.

Roy smiled faintly, "The price is high, but it's worth it. Kaido has dominated the New World for decades with his Fish-Fish Fruit, Model: Azure Dragon; it's time for our Navy to have its own 'dragon'."

Garp hesitated for a moment, then suddenly grabbed Roy's shoulder with such force that the ground cracked. "Do you know what this means? If the Five Elders find out..."

Roy met his gaze without flinching. "That's why Luffy needs to master it as soon as possible!"

He then turned to Luffy, who was still rubbing his head on the ground, and said in a deep voice, "Luffy, eat it."

"Huh?" Luffy's eyes widened immediately upon hearing this, and he shook his head frantically. "No way! Eating Devil Fruit I can't swim anymore!"

Upon hearing this, Garp raised his hand and delivered a solid Iron Fist: "Idiot! Do you know what this fruit means? It's a Logia- Mythical Zoan! And it's the powerful Azure Dragon Form of Mythical Zoan! Do you know how much risk Roy took to get it back?!"

Luffy, clutching his smoking head, muttered aggrievedly, "But..."

Roy crouched down, meeting Luffy's gaze, his voice softening yet serious. "Luffy, do you want to become stronger?"

"Of course I want to!" Luffy answered without hesitation, his eyes resolute.

"Want to punch the Pirate King like your grandfather did?"

Luffy's eyes lit up instantly. "Yes!"

"Do you want to protect Ace, Nami, Nojiko, and everyone else you care about?"

Luffy clenched his fist and shouted, "Of course I want to!"

Roy handed the box to him and said softly, "Then, accept the power of this fruit and become the strongest dragon in the Navy!"

Luffy looked at the fruit, glanced at his grandfather's expectant eyes, gritted his teeth, and stuffed it into his mouth.

"Ugh--!" Luffy exclaimed in pain, "This stuff tastes awful!!"

Garp and Roy exchanged a smile, silently stepped back a few paces, and waited patiently.

A moment later--

"Boom!!"

A violent energy storm erupted from Luffy's body in an instant!

As the smoke cleared, Luffy's new form was clearly revealed to everyone.

He still retained his human form, but his height had increased significantly, and his physique had become more slender and robust. His entire body was covered with a layer of light pink dragon scales, which shone with a delicate and soft luster like pearls in the setting sun.

His arms and fingertips had completely Dragonization, and his sharp Dragon Claws gleamed with a chilling sharpness.

Two silver dragon horns curving backwards grew from either side of his forehead; his black hair was slightly long and flowed freely; his pupils had turned amber, and his vertical pupils were sharp and majestic.

At this Luffy is like a true "Dragon of the Navy," handsome and domineering, powerful yet Haki, exuding an aura of majesty and power that can awe the world with every move.

"Whoa! Why does my hand itch?!" Luffy frantically groped for his Dragon Claw, panicked yet excited.

Garp stared in disbelief, his beard trembling slightly. "Luffy... he really did turn into a dragon!"

Roy nodded in satisfaction. "After Vegapunk's improvements, the violent element of this fruit has been removed, making it more suitable for Luffy's personality."

However, before the two could even celebrate—

Suddenly, Luffy's stomach rumbled in his Human-Beast Form. Touching his stomach, Luffy said in confusion, "It feels weird in my stomach..."

The words had barely left his mouth when he instinctively opened it. "Dragon Breath!!"

A scorching and dazzling pink Dragon Breath shot out from his mouth, and a pink Fire Pillar with a diameter of three meters instantly pierced through the distant cliff. Rocks and dust collapsed into the sea with a violent roar!

The scorching Dragon Breath instantly melted through the clouds, drawing a magnificent trail of light in the twilight.

"..."

Garp and Roy stared silently at the cliff face with its massive crater blasted open, remaining speechless for a long time.

After a two-second silence, they roared simultaneously, "Luffy!!"

Luffy scratched his head Dragon Claw and chuckled, "Hehehe, I accidentally... I couldn't control myself."
