——I traveled through time and space as a poisonous sea snake from the East China Sea. I started by devouring a giant octopus.

——After twenty years of crazy evolution, when I grew a thousand-meter snake body and patrolled the East China Sea, the only sound in the East China Sea was the wailing of sea kings.

——On the day Luffy set sail, I stopped him at the port of Windmill Village: "Boy, you want to be the Pirate King? Give me a ride!"

——The Straw Hat Pirates were still in panic when giant sea kings swarmed in.

——The giant snake shook its head slightly: "Who's hungry? Today's buffet begins."

——Luffy's eyes lit up as he watched the thousand-meter basilisk easily swallow the King of the Near Sea: "Cool! Come on board, Uncle Viper!"

This book is extremely messy and completely haphazard; it's basically just writing whatever I dream about.

Transmigrating from birth into the world of One Piece, he became the World Government’s strongest talent in 800 years: the CP9 killing machine, Rob Lucci.

By all rights, this should have been the ultimate overpowered transmigration. But thinking of his future self—first sent to work as a shipwright in the trenches, failing the mission, then treated like a roadside nobody, and finally returning as a king yet still mocked as “the Ultimate Brother” by the world—Lucci felt his prospects were completely doomed.

Fortunately, fate is fair. After enduring a hundred blows from Kaido, destiny finally took a turn.

“Kid, come aboard my ship and become my crew!” The Governor of the Beasts, the strongest creature, and one of the future Four Emperors—Kaido—laughingly extended his fist toward the young Lucci.

Thus, boarding the Beasts’ flagship, Lucci proved to the world the true worth of the strongest talent in 800 years.

Luo Lan traveled through the pirate world, becoming captain of the Whitebeard Pirates' Squad Zero and activating a god-level manga system. He knew full well the fate of the Whitebeard Pirates at Marineford. So, he retreated to gain experience and improve his own strength. With the Battle of Marineford imminent, Whitebeard needed a period of intensive treatment due to health issues, so he temporarily appointed Luo Lan as acting captain of the Whitebeard Pirates. Months later, when Whitebeard completed his treatment, he was utterly stunned! Marco: "The Undying Flame is the true way to activate the Phoenix Flame!" Jozu: "Eighth Death Gate, open! Who can withstand my [Night Jozu] move?" Vista: "When I master the dual-sword style, my Zanpakutō, Nosei, that's when you prepare your final words!" Little Oz: "The super-multiplication technique in Butterfly Transformation Mode is so fascinating!" ... Whitebeard: "I asked you to temporarily take charge of our group, and you've actually raised the captains' strength to that of a general?!!"

"Uchiha of the One Piece World," "Marine Admiral," "Smoker's stepsister," "The Celestial Dragons' lifelong nemesis," "Is Sharingan + Ice Release + Devil Fruit a viable combination?" "Ancient Zoan - Snow White Wolf!" "The Navy's peak of handsomeness in 800 years!"

Borsalino: Compared to that brat, we're ashamed to be called monsters.

Sakazuki: Although he's an ice-wielding guy like Kuzan, I felt this kid's burning sense of justice!

Kuzan: Compared to that, my fighting style seems incredibly crude.

Sengoku: He will be the future of the navy! A pillar of the navy! (Most importantly, his face boosted his recruitment rate by several points.)

Garp: I have a feeling... this guy will unleash a storm of a great era, just like Roger!

...

Ten years later, the Marineford War.

When the Sharingan's gaze fell upon Marineford...

Allen spoke softly.

"The winners don't care what the world is like, they care about how they make it..."

"And I am the victor!"

"Schrödinger's heroine," "decisive and ruthless," "ruthless and vicious," "arrogant? What kind of young person isn't arrogant?!"

It's time to show the world a fighting style that's no longer suited to this era!
