Bad news: I traveled through time during the duel.

Good news: This is not the world of Yu-Gi-Oh! No need to gamble your life playing cards.

Bad news: This is the world of One Piece! You can't survive without fighting.

Good news: There is a cheat code. Bad news:

The original male body has been replaced with a mouthful of teeth!

Good news: The new body is even stronger! Domineering! Strong! ! ! "

Immortal! Immortal! And then... Phantom Power!"

"Kaido, you will be defeated today! Phantom turns one million horses - Super Conductive Wave Thunder Cannon Muzzle!!!"

...

"Hehe~ Hehe~"

"Ossi, Ossi? Wake up. Captain Kaido is calling you."

In the meeting hall of Onigashima, a red-haired girl who was talking in her sleep was gently awakened.

"Ah, ah? What's wrong?" The girl looked up blankly and saw Kaido's big face. "

Woooo ...

Su Chen traveled to the pirate world with a magician's inheritance.

After learning most of the magic, he met Luffy who had just set sail and accepted the invitation from the future Pirate King.

What kind of collision will occur between the gorgeous and magical magic and those magical devil fruits?

Nami, come here, let me strengthen your wind-type celestial magic!

Usopp, do you know about the magic bow and various attribute ammunition?

Sanji, do you want some top-quality ingredients from around the world? And some invisibility magic?

Hey, Robin, everyone has their own meaning of existence. If you don't even have the courage to try, you don't deserve happiness at all!

After being strengthened by Su Chen, would Luffy and others still watch Ace being killed during the Battle of Marineford?

All regrets will be made up!

The West Sea is a sea area ruled by gangs, but it also has countless powerful pirates.

Ever since Andy got the bounty point system, the guys with bounties in this sea area became his targets!

Ghost Assassin Moon, Enchantress Luna Meiyan, Bonebreaker Bruno, Flame Fist Royce, Mad Axe Tobias, these long-famous pirates in the West Sea have all been defeated by Andy!

But this is just the beginning!

Killing pirates was no longer enough for Andy, so he teamed up with the richest man in the ocean and began to offer rewards to the navy and the Celestial Dragons. Thus, the terrifying God Killer was born!

Besides killing, the protagonist also has some tenderness, is passionate, and may also do some treacherous things...

If there are any bad parts in the writing, please tell me in the comment section. I can see it in the background and make reasonable changes.

P.S.: There's no justice in this book. Regardless of whether they're pirates or navy, they're all treated as pirates. As long as there's a bounty, the protagonist will kill them all, pirates or navy alike. Anyone who provokes him will be killed! It doesn't matter if the other party is guilty or not! If you mind... forget it, mind it!

If the Tremor-Tremor Fruit is a natural type

If the Navy had a "Whitebeard"

Then, this sea will crawl under the new meaning of "shock"!

Even if this justice... is itself a natural disaster!

Others travel through One Piece: The Prophet System Gold Finger.

Gern travels through Pirates: Landing in the Rocks Dark Age! Script? It's already been fed to the dogs!

System? It doesn't exist!

The only option: Join the navy! Stay alive!

After four years of hard work, he finally became a private, took out a loan, risked his life, and used connections to sneak into the battlefield of the Island of Gods.

In the end, I still hadn't touched the center, and was stunned by the domineering force for at least fifty times.

But when he opened his eyes for the last time, he found a fruit of unknown origin in his arms. Seeing this, Ge En made up his mind and ate it decisively.

However, the moment he bit into the fruit...

Space shattered! The atmosphere wailed!

The elemental body is the source of the earthquake, and the air vibrates when he raises his hand!

Natural system: Skyquake Fruit!

Gern: "??? Shouldn't this familiar special effect be a superhuman one? How the hell can this be a natural one?!"

From then on, the Navy Headquarters received a "human-shaped disaster"

…

Gern's declaration of justice: "Get out of the way! I'm about to start the execution of justice!"

Gorn's motto as Field Marshal: "If justice requires natural disasters to reshape... then starting today...

My justice is natural disaster!"

Luen journeyed through the pirate world, gaining access to the most powerful stat system, allowing him to plunder other people's stats. Looking at the golden stats on the Deserter King Coby, Luen exclaimed, "You clown, you deserve it? Take it!" Then, Luen plundered even more powerful stats. Marine Headquarters: "He is a monster capable of devouring and robbing everything, the most vicious esper in history. Without permission from the highest levels of the World Government, you must not engage him! The world's most dangerous man! 'King', Luen! Live or die! Bounty: 3.9889 billion berries!"

He traveled to the world of One Piece and merged with the world's strongest creature to become the new Four Emperors: Kaido, the King of Beasts.

Logically speaking, this is an absolutely high-end time travel, invincible from the start!!!

But when he thought that he had come to the world of One Piece, and as the villain, he was about to face the unreasonable Child of Destiny, Master Joyboy, the user of the Nika Fruit, and the only designated savior: the Sun God.

Kaido felt as if he was invincible.

Sit-ups, version update, and martial spirit awakening!

Is he destined to follow Kaido's old path and become a stepping stone for Luffy to become the emperor?!

Fortunately, you are the child of destiny, and I am a time traveler.

If you have Nika, I can cultivate immortality.

Watch how I, the new Kaido, cultivate my immortality and defeat Nika, and restore order to the pirate world!!!

【Invincible + Daily Travel + Concept God】

'Ding Dong!'

"It has been detected that the host has been designated a dangerous individual by the Five Elders. New crew members are being recruited—"

"Ding Dong, we have successfully recruited a new companion for the host. Drupi Bait will soon arrive on the battlefield."

Traveling through the world of pirates, he replaced Luffy who was not yet born, and gained a gift of incomprehension that defied

the heavens. Since then, Luffy has created all kinds of incomprehension abilities.

When the Straw Hat Pirates appeared, the whole world was shocked...

Ryan was reborn in the world of One Piece. His parents are unknown. He was picked up and adopted by an old man. Fortunately, he was born with Observation Haki. The most important thing is that Ryan is also bound to a god-level cooking system. The cooking levels are divided into general, fine, excellent, top, master, unparalleled, and god-level. He even conquered Rocks with his cooking skills. In order to upgrade his cooking skills, Ryan joined the Rocks Pirates. When Whitebeard, Golden Lion, Kaido, Big Mom... these legendary pirates boarded the ship one by one, they found that this pirate group was really a paradise for gourmets. Ryan, as a cook, became the vice-captain of the Rocks Pirates. ... Steel Bone Sora: "If Ryan, this guy, wasn't a cook, his bounty would probably be higher than Rocks!" Garp: "Sooner or later, I will capture this guy Ryan and bring him to the Navy Headquarters to be a cook!" Protagonist: Ryan
