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!"

(New book has been opened, Pirates' Technology Template)

Uchiha Obito: The Fifth Shinobi World War begins now.

Narrator: Why the fifth time?

Uchiha Obito: Because there was a ruthless man who fought the Fourth Ninja World War alone.

I alone am the war, traveling through the world of ninjas, fighting a war of technology.

It has a variety of technology templates, including Transformers, Terminators, Star Destroyers, space-based weapons, Green Goblin bombs, machine guns, heavy artillery, nuclear bombs, accelerated particle cannons, Red Alert bases, and robot production lines.

After traveling through Naruto, he became the weak villain Mizuki, and every step he took could lead to a bottomless abyss.

Fortunately, the system is activated and the rewards for teaching are ten thousand times higher.

Granting your apprentice ninjutsu, illusion techniques, physical techniques, ninja tools, items, etc. will receive a system reward of up to 10,000 times.

【bite!】

[You give Naruto a bowl of miso chashu ramen, triggering a thousandfold return.]

[Congratulations on getting a bowl of miso chashu chakra noodles. Eat it all and your chakra limit will increase by 1, Kakashi.]

【bite!】

[You grant Uchiha Sasuke the water-treading training method, triggering a ten-thousand-fold return.]

[Congratulations on acquiring the art of stepping on air. You can step on the air and spiral upwards, and even stay in the air for a short time.]

…

Naruto tradition, teaching the apprentice to kill the master?

That doesn't exist. To me, the master is always stronger than the apprentice.
