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!!!

This is not a reincarnation/reincarnation novel! I wanted to write a fanfiction after watching One Piece! The protagonist will definitely join the Straw Hat Pirates! The overall world-building and power system will remain completely faithful to the original work! The outline will follow the plot development! Original storylines will be added! This book is a One Piece anime fanfiction! (For readers who like wish-fulfillment fantasies, characters with cheat codes, or completely original content! Sorry! This book cannot do that!)

"Gulala, Ace, are you okay?" Whitebeard stood at the bow of the Moby Dick and looked at the execution platform.

"Whitebeard! You've come as expected, and this time you're destined to never come back!" Zhan Guo shouted at Whitebeard.

"Oh? Going but never coming back? I'm afraid that's not up to you." A blond boy moved and appeared beside Whitebeard.

"Who are you?" Zhan Guo looked at Leiduo in confusion.

"Edward Reardo!" The young man waved his staff, creating a strange phenomenon in the sky and on earth.

"Gulalalala, let's have a big fight today, brothers!" Whitebeard activated the Tremor-Tremor Fruit, causing a huge tsunami.

Crossing over to the world of pirates(the one piece world) , in the era of pirates, the Roja from eleven years ago obtained a Sword Soul system that lets him strengthen infinitely and extract various kinds of skills.

Flowing Blade-like Flame (Ryūjin Jakka) , Mirror Flower, Water Moon (Kyoka Suigetsu), Moon Fang Heaven-Piercer (Getsuga Tensho), Thousand Cherry Blossoms (Senbonzakura)……

“If this sword descend, you may be roasted to death.” Roja looked at Akainu in front of him and seriously said.

Eden traveled through time, but he was not panicked at all. Because this was his second time traveling through time.

The last time, he traveled to an anime world called "Fairy Tail". Unfortunately, he had heard of it but had never seen it...

So he worked hard for six years, relying on the mental power of a traveler and his magical talent, and successfully passed the guild's S-level magician assessment...

And in X784, when he first boarded the Sirius Island as an S-level examiner, he was blown away by the final boss of the whole play, a black dragon that was immune to magic.

Yes, you heard it right, a world of magic, and the final boss is immune to magic, how can you beat him? !

As for this second time traveling, when Eden looked at the man in front of him, who was more than two meters tall and extremely ugly, and kept saying low...
