Bai Yu came to the Naruto world as a second time traveler from the wizarding world.

The "Book of Ancient Sound Magicians" in his soul made him see the possibility of becoming a high-level wizard.

......

Although the fireball is powerful, its flying speed is not as fast as the improved level 0 spell [Acid Missile].

When the Impure World Reincarnation meets the [Soul Binding Technique] and the Flying Thunder God encounters the [Dimensional Lock], who is stronger?

......

"As we all know, wizards are all-encompassing, and sorcerers are a branch of wizards. So it makes sense that I know some ninjutsu, right?"

After saying this, silver-white scales grew all over Bai Yu's body, and he turned into a giant snake.

"The universe is vast, but I only take one bite!"

In the Ninja World, the only thing that can defeat a "cheater" is science!

Geneticist Dr. Kinos!

Dr. Tenma, the father of Astro Boy!

Capsule expert Dr. Brief!

The genius scientist Dr. Vegapunk!

Senbei Norimaki!

Grey Wolf...

Wait, isn’t the last one a bit too much for the ninjas?

Eiji traveled through Naruto and became an ordinary Uchiha clan member.

Facing the night of genocide three years later, Yingsi had a headache.

At the critical moment, successfully activated the [Strongest Template System] and bound the [Thousand Hands Tobirama Template]

From now on, I am the man who has signed a contract with the sea!

Flying Thunder God, Master of Forbidden Techniques, Ninja Scientist, and even Immortal Techniques, all of them were mastered.

From then on, Eiji bore the name of Uchiha, but became the shadow of the Nidaime.

[The Sharingan that Tobirama got from somewhere has been successfully upgraded to the Mangekyō Sharingan! 】

[Master Tobirama resolved the rebellion at the lowest cost. You are worthy of me! ]

[Wait, Master Tobirama has become the head of the Uchiha clan? ]

Until one day, the light of the Impure World Reincarnation came on...

Senju Tobirama was completely stunned when he saw the white-haired, red-eyed Uchiha kid who was skilled in all kinds of forbidden techniques.

"How come this naturally evil Uchiha brat looks exactly like me when I was young!"
