Bai Yu traveled to the world of One Piece and activated the strongest swordsman system at the beginning.

No need to practice, swinging a knife will become stronger!

Thus, Bai Yu started his daily routine of wielding a knife.

Swing the knife 1000 times, and get the limit of physical strength – six styles.

Swing the knife 2,000 times to obtain the powerful Qinglong Sword Intent.

Swing the knife 3000 times, get three-color domineering.

General Huang Yuan: Bai Yu is the strongest rookie I have ever seen.

General Aokiji: My freezing ability was directly chopped into pieces by Bai Yu!

General Red Dog: Dangerous! My marshal position is about to change!

Hawkeye: Bai Yu is the number one swordsman in the world!

Since then, the name of Bai Yu has resounded throughout the world of pirates.

Lin Ruhai transmigrated, but simultaneously traversed countless worlds, each of which he assumed a minor, insignificant identity. Even the cheat-like abilities that transmigrated at the same time could only share memories, not power. Even so, he refused to give up. Every Lin Ruhai was me, but each version of myself had a different environment, experiences, and way of thinking. When countless different minds opened their hearts and communicated without any barriers, countless wisdoms would emerge. *Laughing at the World*, based on the Evil-Repelling Star-Absorbing Technique, forging the Burning Heart Great Art—as long as the heart is extinguished, I am immortal. *Under One Person*, drawing three corpses from the body, merging demonic thoughts into the Dao, cultivating three hearts and two minds. *Infinite Terror*, four inner demons, cellular rebellion? But I am all, and all is me. *Covering the Sky*, I, one of the two great immortals, aspire to become an immortal for eternity. *Lord of Mysteries*, beneath the witch's skirt, the hunter sets fire...

"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!"

With the aim of hunting down the Celestial Dragons, he used a dual identity to rise through the ranks of the Marine Headquarters, becoming the youngest admiral in history!

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!

[Navy + Genius + No Male Lead + Emperor + Single + Dual Personality] Esdeath, though reborn as a Celestial Dragon, remains blind, a congenital visual impairment. But so what? She still slays the world's strongest swordsman! She still beats up the Five Elders, and the Four Emperors give way when she goes out! Even the future Pirate King can't withstand a single strike from her sword! Being a swordsman in the pirate world isn't so bad! PS: This is a story about becoming a swordsman, farming and dominating the pirate world!!

Upon transmigrating to the world of One Piece, Li Tian successfully awakens the Fabrication System. From then on, he decides to bring a shocking performance to this distorted world of pirates.

...

During her rescue of Kuma, Bonney's Year-Year Fruit awakened, transforming her into Nika form. She then took all the Yonko-level Seraphim created by Vegapunk under her command, single-mindedly seeking revenge for her father.

Rocks faked his death in the Valley of the Gods and spent decades regaining his will. He returned to the sea and gathered his crew to conquer Mary Geoise.

Bucky the Joker separated his consciousness and Haki, and just as Shanks was dying, the power he had split off returned, intending to drag the entire world into the Dark Ages.

The navy was struggling to cope with the rapidly expanding pirate forces and had to expand its military on a large scale to prepare for war, increasing the number of admirals to 12.

Straw Hat Luffy successfully received the inheritance of Shendu and ate the Balance Devil Fruit (Tiger Talisman), which can balance the demonic power within him.

...

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

Naval Headquarters - Marineford

Sengoku: "Hey, Heya, what's this? You're joining in the fun too? What a fitting ally!"

"Ah, Marshal, you've misunderstood. We're not like that," the person whose name was mentioned stroked Perga's mane and responded with a chuckle.

"Oh? So you are... This isn't a place where you can change your mind based on the wind."

Sigh—Heya was a little helpless.

Sure enough, it must be because of the beard!

Heya: "Are we really that different? You have to take some responsibility for that, Dad—"

"Gurararara, isn't it great that you look like your mother?" The white-bearded man couldn't help but laugh out loud as he glanced at his youngest son, who was leaning closer with a resentful expression.

navy:???!

………

"Oh well, I'll just introduce myself anyway."

Edward Hea

"This is my name."

...

P.S.: I recently got hooked on One Piece, and my brainstorming session with friends about how the Whitebeard Pirates could continue to exist at sea led us to the conclusion that they needed a successor, haha.

P.S.: I really like mystery and always wanted to write related fanfiction, but I ended up in the One Piece fandom, so this strange stuff came out. (Private message: Masai, wadsweetie, it wasn't intentional.)

The Halle Codex records:

"On the earth, there is [fire]."

Humanity succumbed to desire and touched the forbidden sun.

The enslaved people prayed,

Then the "Sun God" descended.

…

"I got to this point without making any effort; it's all thanks to my talent and ability."

He was Cavendish, the sole heir to the Kingdom of Brugesia, but because he was too handsome, women in the kingdom were unwilling to marry him, so the king exiled him for the crime of being "too popular."

Even on the high seas, he remained just as popular.

By a twist of fate, he found the legendary Flame-Flame Fruit, which even dogs wouldn't eat, but he discovered that the fruit wasn't as bad as the rumors suggested.

Where does the mysterious alternate personality come from? What does the blue Sharingan really mean? What secrets does the Flame-Flame Fruit hold?

(Everything Cavendish does is based on reasonable reasoning from the original work, ensuring it's not offensive.)

What to do when you're out at sea without a ship? Allen: "Steal someone else's." What to do when there's no one on board? Allen: "Dig someone else's." What to do when there are people but no supplies? Allen: "Rob a warship." Treasure, famous swords, Devil Fruits, where do the women come from? Allen: "Brothers, look! There's a transport ship that's practically floating on air, it has everything!"... Transmigrating to the world of One Piece, relying on Baki's cheat abilities to rise to power in the East Blue, starting with just his fists, he steals everything—people and ships. My name is Allen, and I advocate for freedom. (A million-word completed high-quality One Piece fanfiction is already available; readers are welcome to jump in and get crazy!)
