New World, Marine G-5 Base.
Beep~ Beep~ Beep~
The highest-level red alarm blared as explosions erupted throughout the base.
"Damn it, all hands, prepare to fire!!!"
Boom! Boom! Boom!
Dozens, even hundreds of artillery shells rained down in one direction, triggering a chain of massive explosions.
"Did we win?"
A Marine asked hopefully.
"No! Not yet!"
Another Marine spotted a figure emerging from the smoke and dust of the explosions.
"Sea-Stone Unit, fire!"
At the command of a Rear Admiral, dozens of Sea-Stone Nets were launched toward the towering, demonic figure.
"Hahaha, we got him! Perfect!"
"He's a Devil Fruit user. Once trapped in the Sea-Stone Net, he won't be able to escape!"
"We've won... We've captured this monster, hahaha!"
Cheers and excited shouts erupted among the Marines.
Yet, in the very next second, all jubilation came to an abrupt halt.
The smiles on the Marines' faces vanished, replaced by utter despair.
"He... he actually tore through the Sea-Stone Net... Is this... the strongest creature on land, sea, and air?" the Vice Admiral base commander muttered in terror.
Crack!
A thunderbolt split the sky, its blinding light connecting heaven and earth.
"Gurarararara~"
An Azure Dragon soared into the heavens, unleashing a scorching Dragon Breath that annihilated everything in an instant.
"Burp~ Still can't die today, huh? But the Marines' booze... not bad, burp~ Where to next? Oh right, there's that island surrounded by storms..."
...
...
New World, Sirius Island.
This was a unique climate island perpetually encircled by the Storm Sea.
Endless tempests raged at its periphery, preventing ships from approaching.
Only the island itself, like the eye of a typhoon, remained eerily calm.
At this moment, the southwestern corner of the island.
Whoosh~ Whoosh~
A torrent of blazing flames surged.
"Fire Dragon's Iron Fist!!!"
Luo Xia, dressed in wildman attire, leaped into the air, his fist wreathed in roaring flames.
"Awooo~"
A hundred meters ahead, a massive white wolf, over ten meters long, howled and charged at Luo Xia, jaws agape.
Bam!
Boom!
Kaboom~
Luo Xia's fiery fist collided with the white wolf's face.
The sheer force of the impact sent the colossal beast flying, smashing through over a dozen towering trees before it finally collapsed, motionless.
The forest ignited from Luo Xia's attack, but before the flames could spread further, he inhaled deeply. The surrounding fires were drawn toward him as if by an unseen force, all eventually swallowed into his mouth.
"After eating that, power just keeps surging. Time for another round."
Luo Xia's gaze shifted to the giant creatures watching from a distance, selecting his next opponent.
A ten-meter-tall silverback gorilla, a serpent over a hundred meters long—Orochi—along with a giant mammoth, an ancient brachiosaurus... all trembled in fear.
These were the island's native creatures, each once ruling their own territory without conflict—until ten years ago, when everything changed.
A decade prior, this isolated island welcomed an unexpected guest.
Luo Xia.
A transmigrator from Blue Star.
One day, stepping out his door, he hit the jackpot—courtesy of a "just trying to survive" driver who floored the gas pedal and sent him hurtling into this world.
Suddenly stranded on this monster-infested island, Luo Xia, too, had once trembled in fear.
Fortunately, his birthplace was a safe zone where monsters wouldn't approach the giant tree at the island's center.
Beneath the tree, Luo Xia discovered a treasure chest containing his newbie starter pack—Fire Dragon Slayer Magic!!!
This ability was all too familiar to Luo Xia, as it was the signature magic of the protagonist from the passionate... fanservice-filled manga Fairy Tail.
Dragon Slayer Magic—a lost ancient magic said to have been used to combat dragons.
Fire Dragon Slayer Magic allowed its user to freely manipulate devastatingly high-temperature flames for attacks.
Additionally, Dragon Slayer Wizards could transform their bodies to possess draconic physiques, granting them combat abilities and stamina far surpassing ordinary humans.
They could also rapidly restore magic power and stamina by consuming flames, maximizing their battle endurance.
One could say Dragon Slayer Magic was an all-around power combining martial arts, elemental control, and superhuman abilities.
Between the giant tree covering the entire island and possessing Fire Dragon Slayer Magic, Luo Xia was almost certain he'd been transported to the Fairy Tail world.
Moreover, his current location was none other than the sacred ground of the Fairy Tail guild—Sirius Island.
This theory was soon confirmed when Luo Xia found a stone tablet on the island bearing the faintly recognizable characters for "Sirius."
Initially, realizing he'd entered the Fairy Tail world filled Luo Xia with excitement. He fantasized about joining Fairy Tail and having passionate interactions with Lucy, Erza, Mira, Wendy, Natsu, Gray...
However, he soon realized a serious problem—he was trapped. The perpetual storms surrounding the island made escape impossible. Even if Luo Xia had a boat, it would never survive the Storm Sea.
Secondly, the Fairy Tail world wasn't just about the wonderful Fairy Tail guild—there was also the terrifyingly powerful Black Dragon King Acnologia, who slaughtered every dragon he encountered, including Dragon Slayer Wizards.
As a practitioner of Fire Dragon Slayer Magic, Luo Xia would be considered a dragon in Acnologia's eyes. If they accidentally crossed paths, even if Luo Xia mastered Fire Dragon Slayer Magic to perfection, he'd be instantly annihilated without a chance to fight back.
Luo Xia had no doubts about Acnologia's capability—after all, even God Serena, leader of the Ishgar Four Heavenly Kings who wielded the power of eight dragons, had been instantly defeated.
For safety's sake, Luo Xia decided to rely on the protagonist group's protection. He would train and grow stronger on Sirius Island while waiting for the Fairy Tail main cast.
This wait lasted ten years.
During this decade, Luo Xia diligently practiced daily, mastering Fire Dragon Slayer Magic to its fullest potential.
All the island's beast kings had been thoroughly beaten into submission, obediently serving as his training partners.
"Day 3,653 without Fairy Tail's arrival."
Luo Xia withdrew his gaze from the sea, preparing for another round of combat.
Just then, a thunderous explosion shook the entire Sirius Island.
Luo Xia whirled around to see billowing smoke rising from the forest several kilometers away.
Minutes later, Luo Xia arrived at the scene to find a hundred-meter-wide crater.
Swirling sand and dust obscured visibility, but Luo Xia's enhanced Dragon Slayer senses detected an intense beastly presence within the pit.
He remained cautious, silently observing as the dust settled—if this turned out to be the Black Dragon, he'd turn and flee immediately.
Rustling—
Movement stirred within the giant crater, tearing through the haze to reveal its true form.
When he clearly saw the creature in the pit, Luo Xia's eyes widened, his mouth gaped open, and his entire body froze in stunned disbelief as he stood rooted to the spot.
After waiting for ten years, Luo Xia hadn't encountered Fairy Tail—instead, he had encountered... a dragon!!!
Not the Black Dragon Acnologia, but... the Azure Dragon Kaido!!!
This wasn't the world of Fairy Tail—it was the world of One Piece.
"What the hell?! I was all set to take the S-Class Mage exam, and now you're telling me this is One Piece?!"
