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!!!

(Naruto + Boruto + Sand Village + Invincible + Farming + No System)

Traveled to the world of Naruto and became the tragic fourth Kazekage Rasa...

Temari, Kankuro, Gaara's stepfather...

But, even without a system...

There is not even an immortal body or immortal eyes...

He even became the [vessel] of the Otsutsuki inexplicably, and was injected with a [wedge]...

Fortunately, Luo Sha did not accept his fate...

At least before being possessed, the ability of [Wedge] was still quite useful...

So, we start to attack the Land of Fire, develop the ninja village, seize the tailed beasts, stars, and dragon chakra...

When I gradually discovered the secrets of the wedge in myself...

Naruto also becomes Kazekage...
