[Option 1: Become King] [Option 2: Become the Protagonist of a Light Novel] [Option 3: Become the Blue-Eyes White Dragon] Looking at these three options, a true time traveler wouldn't hesitate at all. Is there even a need to choose? The chance to be human is there in every lifetime... but the chance to become a Blue-Eyes White Dragon might only come once in a lifetime! ...That day, Artoria, following the villagers up the mountain to quarry stone, could never have imagined that the white stone she brought down from the mountain would actually contain a blue-and-white baby dragon.

Earthman Romon, his soul split and reincarnated through 99 worlds!

The core of his soul reincarnated through the Naruto world, and met Hinata Hyuga by chance, and looked at each other.

Romon knew that the princess of the Hyuga clan, Hinata Hyuga, was the reincarnation of a corner of his soul fragment!

When the two are close, their souls will resonate and their abilities will be sublimated.

In order to become stronger, the two held hands and hugged...

In order to obtain more chakra, a more advanced blood net, pure eyes, and reincarnation eyes... Only a little time has passed, and the two have stood above the sky and become existences above the six paths!

And Romon's soul fragments are far more than the Hyuga Princess Hinata of Naruto, there are also the original God of Water Kingdom Fontaine God Fu Nina, the little fox Pingping of the black myth, and scattered in the worlds of Collapse, Lingcage, Giant, Collapse, Zongman... and so on.

People who have reincarnated from various soul fragments, including Romon, can communicate and talk through a mysterious black fog hall of fate, and contact...

Ethan's soul was thrust into the Marvel universe, but unlike many others in his situation, he didn’t receive any overpowered system to guide or assist him. Instead, fate had a different plan.

As he reached adulthood, he awakened as a mutant—an incredibly powerful one at that. His ability? Vector control, a power that allowed him to manipulate forces and motion at will, much like Accelerator. With this, he became an Omega-level mutant, a rarity among his kind.

But Ethan wasn’t content with just existing. He saw the grim fate that awaited mutants and made a vow—to change everything, to turn the tide, and to lead his kind to glory.

Professor X:. "Ethan, I am old. My time is running out. From now on, the responsibility of safeguarding world peace and ensuring the future of mutantkind falls upon you."

Magneto: "Charles, always the diplomat. But tell me, why do you assume you have the first claim? If anyone is to guide Ethan, it should be me. He should inherit my vision, not your dream of coexistence."
