Water, earth, fire, and wind. People who can control one of these elements are called firebenders. As a result, four nations and tribes were born in the world: Water, Earth, Fire, and Air.

Among them, only the Avatar-Avatar can master all four elements at the same time. It serves as a bridge between the four nations and maintains the balance of the world.

However, just a hundred years ago, the Avatar-Avatar suddenly disappeared. One of the four nations, the Fire Nation, launched a war of aggression against the other three nations, which lasted for nearly a hundred years.

At this time, Kahn traveled through time and became a young firebender...

"So, the reason of Sharingan going from one magatama to two magatama and then three magatama a genetic mutation or something else?" Looking at the test subject in front of him, Kenichi Amemiya showed a look full of curiosity.

"...I always feel that the way this disciple looks at me is not right." Orochimaru held the "Research Report on the Effects of Soul Reincarnation on the Body" submitted by Kenichi Amemiya in his hand, his face

(This book has no system, slow to start, and only has a female protagonist. Let's see how Minato becomes the strongest in the ninja world step by step!)

"Hokage-sama, Hokage-sama, may I ask how you became so strong?"

Minato thought for a moment and said, "It all started when I fell off a cliff when I was five years old. I was climbing to train, but I ran out of energy and fell off a cliff, and that's when I learned some magical skills."

"Ah? It's that simple?"

"Of course not, this is just the beginning of my legendary life!"

(No system + non-Uchiha protagonist + ninjutsu development + reasonable logic)

I was reborn into the world of Naruto, but I didn't become a member of the Eye Legend. But without the system, how can I live?

Fortunately, I still remember the cultivation of immortals in my previous life. Watch me become a legitimate immortal of the human race! Develop ninjutsu, develop storm escape, and develop the immortal mode of the human race! I can become the strongest in the ninja world!

If Uchiha can implant Hashirama's cells, then as a descendant of the Senju, can't I get a Sharingan?

[The Dimensional Life System allows you to experience different lives without leaving your home] [Warm Tips: Because the "Real Life" mode is a real journey for the host, there are certain risks. It is recommended that the host choose the "Virtual Experience" mode for the first experience.] "Is there a risk?" After hearing this, Uzumaki Naruto's eyes lit up slightly: "That's it, I choose the "Real Life" mode!" [Special Tips: The "Real Life" mode is a real journey, there are certain risks. For the host's first experience, it is recommended to choose the risk-free "Virtual Experience" mode.] "I don't accept your advice!" Uzumaki Naruto completely ignored the system's prompts, excitedly clenched his palms, and punched hard, saying: "I will choose the risky "Real Life" mode, let's get started!"

After a close contact with the dump truck, Bai Yulin was transported to the world of Naruto.

However, he was not from the Uchiha clan, but he encountered the night of genocide.

Fortunately, at the critical moment, he obtained the "Universal Divine Eye" system.

In order to avoid the massacre of Uchiha Itachi, the filial son of the ninja world, Bai Yulin relied on the system to enter the trial space and began to practice.

Half a year later, he finally walked out of the trial space without Uchiha blood, but relied on the system to open the Sharingan.

Looking at the monsters constantly emerging around, Bai Yulin suddenly found that this style of painting was a little wrong!

The innocent female swordsman holding a long sword is called "Sword Princess", the "Nine Demon Princess" elf who can use magic...

and there is also a red-haired squinting eye who claims to be a god and insists that he join the clan.

Bai Yulin: "Clan, God... where is this?"

Loki: "Of course it's Orario!"

Shangguan Mo traveled to the Naruto world due to an accident.

In times of crisis, the system that can synthesize summoned beasts was activated.

…

[Stone] + [Earthworm] = [Earth Dragon]

…

[Sharingan] + [Crow] = [Scarlet Moon]

…

[Asura Chakra] + [Anaconda] = [Immortal Xiangliu]

…

[Ichiraku Ramen] + [Chimpanzee] = [Otsutsuki Ichiraku]?

…

Gradually, Shangguan Mo discovered the joy of synthesis.

The five major countries: You’d better behave yourself!

Shangguan Mo: I've traveled through time, so what if I just want to be a shadow?! ?

In Naruto, you should tam beasts!

Psychic Beast: Master, stop looking, come down and join the team fight!

Shangguan Mo: Fight in a group? What group? I will never fight in a group in my life!

Summoning beast: Master, Minato Namikaze wants you to get down, he wants to kill you!

Shangguan Mo: Tsk! As for him, it would be better to call his son!!!

Psychic Beast: He said his son is only two years old...

Minato and Kushina: “Happy Birthday! Make a wish!”

Naruto: “I hope my mother will give me a brother.”

Kushina: “Huh???”

Minato: “Why not have a younger brother?”

Naruto: “Because if it were my elder brother, I would be as gentle and powerful as Big Brother Itachi, and if it were my younger brother, I would definitely be as stupid as Sasuke.”

…

What kind of changes will the traveler Ren Ming become Naruto bring to the Naruto world?

After traveling through time and space and becoming Senju Tobirama, he found that the ninja world he had changed began to become strange.

After he successfully rescued his two younger brothers from the five adult men who besieged his younger brothers,

every time the two younger brothers went out on a mission, they would always be easily attacked by five adult men!

After he changed the eldest brother Hashirama's first encounter with Madara by the river during the day, the eldest brother preferred to run out to meet Madara every day at night.

After failing to kill Uchiha Izuna with the Flying Thunder God Slash, this guy always wanted him to chop him with the Flying Thunder God Slash, and was confident that he would never be cut off by his sword!

After the establishment of Konoha Village, Tobirama, who did not want to study shadow clones or manage the village, and wanted to rest, found that the entire ninja world began to undergo drastic changes!
