When Kaido merged with the soul of an unlucky transmigrator, he learned that the world he was in was a manga, and that he was merely a stepping stone for Luffy, the so-called chosen one of destiny, to defeat him.

"What kind of bullshit is Wang Luffy, Chosen One, Joy Boy? I'm going to smash you all to pieces..."

'Ding, system loading...'

Kaido: "So this is the cheat code of that unfortunate transmigrator? It seems that after merging with that guy's memories, I not only know the direction of the plot, but I also have a cheat code to use..."

'Ding, system loading complete. You are not the host of this system. The system will automatically unbind you. Goodbye...'

Kaido: "Damn it..."

(Cheerful, cold-blooded, ruthless, bloodthirsty, ambitious. Kaido is the Kaido from the original work, but one who knows the plot; his personality won't change much.) (Completed novel: "One Piece, Me, Marco, Starting with the Marineford War")

[Unbeatable background, no system, multiple female characters, doesn't eat beef]

This book is also known as [One Piece: The Strongest Background King] and [Because I don't eat beef, Im said I'm too extreme].

Ace's father was the Pirate King Roger, Luffy's father was the Revolutionary Army leader Dragon, and Teach's father was the former ruler of the seas, Rocks.

Alright, alright, so the world of One Piece has entered the era of relying on one's father's connections, huh!

My name is Narona Ian Saint. My mother lives among the flowers year-round. The Five Elders kneel and call me Young Master. The Knights of God are my personal guards. What do you have to fight me with?

Comparing family backgrounds? My family has a history of 800 years, but it can't compare to your family's three generations of hard work.

"Kicking the Celestial Dragons like a football? Who is this guy to be so arrogant?!"

"What? The Five Elders actually called him Young Master? Then it's alright!"

"They kidnapped Princess Vivi to the Holy Land, and then blew up a restaurant just because she wouldn't eat beef. Is there no law left?"

Ian: "Which law says you can't do whatever you want? I'll make my mom change it!"

[Navy] + [Slightly Abusive Protagonist] + [Justice] + [Transformation Novel]

The girl, who had endured many hardships, became a member of the navy, and sang her own song of justice.

Smoker: As a student of Professor Zeff in the same year, I am ashamed of myself. Am I the mad dog or is she the mad dog?

Akainu: I greatly admire Erza's sense of justice. All evil pirates should be eliminated!

Sengoku Marshal: Erza, can't you obey orders? Sometimes this world isn't just about passion; there's also human relationships involved. Hey, don't give me that pitiful look as if I'm bullying you.

Hawkeye: I never imagined a girl could reach this level in swordsmanship. Erza, you are a worthy opponent.

Wang Luffy: Everyone run! If the opponent is Erza, we'll really be killed!

Erza: My justice is the sword in my hand. Pirates, you can't escape! Hahahaha!

What kind of storm will a powerful navy that hates pirates to the point of madness stir up in this world?

The protagonist is relatively weak in the early stages, but very brave, so he is often beaten up. There is no system, so he may be almost killed many times. The protagonist has two personalities: combat and social. If you don't like this, please do not read.

[One Piece Fanfiction] + [Invincible Male Protagonist] + [Decisive and Ruthless]

Starting in God Valley, facing a three-way battle between the Navy, Roger, and Rocks, Lynn, a slave, makes a fourth choice—to devour the era!

Having obtained the power of the Mythical Ancestral Dragon, he not only didn't run away, but instead kidnapped the sea overlord, Rocks!

Thus began an unprecedented path to hegemony.

He doesn't want to be the Pirate King because the entire ocean will be his territory; he doesn't want to be a revolutionary because he wants to establish an order even more absolute than that of the Celestial Dragons!

"Im, get off that throne! From this day forward, I, Lynn D. Caesar, am the one and only king of this world!"

Lu Ming traveled through the pirate world and unexpectedly obtained a god-level lottery system!

You can extract skills and items from all the heavens and worlds:

Who is stronger, Fei Tian Yu Jian Liu or the great swordsman Hawkeye?

Who has the strongest physical skills in the Eight Gates vs. Hero Garp?

Who is faster, Quicksilver or Kizaru with the Pika-Pika no Mi?

Which one is the strongest Haki, the full-level Nine Yang Magic Art or the Armament Haki?

With the system in hand, the world is mine!

When Lu Ming looked back, he saw that the followers behind him were Kaido and Red Hair... He was already invincible!

[Fishing for the heavens, the earth, and all the realms, fishing through countless worlds to slay the heavenly dragon!]

"Ding! Congratulations, host, you have obtained the Supreme Grade Blade - Azure Dragon Crescent Blade through fishing!" (Damage is tripled against dragon-type creatures). Who says Celestial Dragons aren't dragons?

Transmigrating to the world of One Piece, Jiang Yu awakens a god-level fishing system, using a single fishing rod to fish through countless worlds!

While others toil for ten years to hone their domineering aura, he cast his line and caught a [triple-color domineering aura experience pack].

Is the cheap liquor in the One Piece world too unpalatable? A casual rendition of a "god-tier Erguotou recipe" conquers the stomachs of Issho, Garp, Sengoku, and others.

During the Marineford War, Sengoku slammed his fist on the table and roared, "Jiang Yu! Did you lure out the Ancient Weapon Pluton to blow up Marineford?"

From a commoner in the East China Sea to a naval admiral, he swept across the Grand Line by fishing.

He fished out the Azure Dragon Fruit and kicked Kaido over; he fished out the Supreme Sword Heart and cut off Red-Haired Griffin with a single sword strike!

When the Four Emperors' allied forces attacked, he unleashed the [Meteor Summoning Technique]: "Justice? I am the calamity of nature!"

As Jiang Yu stepped onto the Red Earth Continent, fishing line entwined around the remains of the Five Elders: "This world has no need for the descendants of the Creator; it only deserves to remember my name!"

"Since the navy cloak is stained with blood, then let's use Im's head... to wipe it clean!"

[High-octane plot]

East Blue Fisherman → Beats Up Seven Warlords of the Sea → Fights One-on-One Against Four Emperors → Overturns Mary Geoise!

[Outrageous Fishing Scenes]

Fishing out "nuclear cola" to get an old lady drunk, fishing out "100,000 tons of sea stone" to smash and collapse the ghost island!

[Complete Subversion]

Akainu: This kid is crazier than a pirate!

Hancock: How did he manage to steal my stockings?

Im: The first person in eight hundred years to terrify me is a lunatic with a fishing rod!

Xia Chen unexpectedly transmigrates to the world of One Piece, activating the story island check-in system right from the start.

"What? You get stronger just by clearing story islands? Doesn't that mean you're about to take off?"

Upon visiting the first island, Windmill Village, I obtained the Zoan-type Mythical Beast Fruit, the Great Sage Equal to Heaven form!

Is Nika the Sun God really that powerful?

Do you know that even if you become a god, you're just one of the 100,000 heavenly soldiers and generals who can stop me?

He then happens to meet Luffy, who is just about to set sail, and at Luffy's invitation, becomes the vice-captain of the Straw Hat crew.

Join the main characters as they explore story islands and grow stronger!

[Immortal! Invincible! Multiple fruit abilities with no side effects, decisive killing, please be careful if you mind entering]

Qingyun accidentally traveled to the world of pirates and was killed by a fishman at the beginning, becoming the fastest traveler to die!

Fortunately, the invincible revenge sea king system was activated, and he was not only resurrected, but also became stronger!

Being killed makes you stronger!

Killing enemies can also make you stronger!

You can become stronger by recruiting subordinates!

[The host subdues Boa Hancock and obtains the power of the Sweet-Sweet Fruit.]

[The host was killed by Jurakor Mihawk (Hawkeye Mihawk) and gained the ability to become the world's greatest swordsman.]

[The host kills Sakaski (Akainu) and obtains the ability of Magma Fruit. ]

(No system + no group + violent aesthetics + Momo-Momo Fruit + old-era powerhouse + semi-invincible + pirate style)

He is the most monstrous genius in naval history, possessing innate Armament Haki.

He is the captain of the 7th Division of the Rocks Pirates, and a world-renowned dual-wielding swordsman.

He was hailed as the hope for the future of the navy.

He is hailed as the world's greatest enemy.

He was Kapzefa's proudest student.

He was the right-hand man that Whitebeard and Golden Lion desperately wanted.

He came from the humblest background, yet he achieved the greatest success!

His name is Fate Roldy!

When justice and evil merge, someone will inevitably appear out of nowhere and cleave the chaos between good and evil!

From God Valley to the Marineford War, an invisible hand has always shrouded the entire ocean!

"As everyone knows, I, Roldy, am a magnanimous person and never hold grudges!"

"So it's time to settle the score for that time you mocked me 17 years ago!"

As the saying goes, the rich rely on technology, and the poor rely on mutation. When Lind mastered the mutant fruit and awakened the farming soul of his previous life's flower-growing family, Lind not only controlled his own destiny, but also had the power to change the world.

Lind hid behind the scenes and first tricked Rocks into following the path of a mustache man in his previous life, and said, "I will stand at the highest place in the world and say to the whole world: 'Stand at attention.'" The authority of the Celestial Dragons was shaken for the first time.

He then tricked Shiki into delivering a pirate version of the Declaration of Independence, further undermining the Celestial Dragons' rule.

By the time Linde had been developing farming for decades and had accumulated immense experience, and stepped forward to say, "I have a dream," the entire world's situation was already in Linde's hands.
