Ninja school teacher, I can become stronger by teaching...

"Brother Naruto, oh no, Naruto, how old are you this year?"

Obito asked quickly.

"Obito, how old are you?"

Naruto asked back, recalling what he said to Obito before they parted.

"Seventeen."

"Then I'm eighteen."

"Like This."

Obito showed a regretful expression. He thought that after so much time had passed, he was bigger than Uzumaki Naruto.

"You idiot, you idiot, you're not here to gather reinforcements, why are you having a tea party and chatting about everything?"

Killer Bee asked Naruto in his unique rap tone.

"Uncle Bi, I understand this, but you don't have to rush. Once you successfully get here, no matter how long you stay, it will only take a moment to go back."

Hearing what Killer Bee said, Naruto quickly explained.

Because time was tight, Naruto came to Loulan with the mentality of giving it a try.

In order to get there faster, he used the Nine-Tails Chakra mode and the breathing method Chakra mode superimposed together to travel.

Unexpectedly, it succeeded on the first try.

"Let's trust Naruto first. If that man is willing to help us, the probability of winning this war will be greatly increased."

The Eight-Tails spoke in the consciousness space.

Although it was the first time they met, Yawei instantly discovered Mu Yue's extraordinaryness.

Not only does Mu Yue have extremely powerful chakra, but he also has the chakra of the nine tailed beasts in his body.

And the Eight-Tails can feel the sense of recognition conveyed by those chakras. He is the second man after the Six Paths Sage to be recognized by all nine tailed beasts at the same time.

"What's wrong with this guy? There's so much of my chakra in his body."

On the other side, the Nine-Tailed Fox also discovered the Tailed Beast Chakra in Mu Yue's body.

However, after traveling through time once, Jiuwei quickly figured out what was going on, and in this world, he recognized Mu Yue.

However, the Nine-Tailed Fox did not communicate with Killer Bee like the Eight-Tailed Fox, but fell into deep thought.

"Brother Mu Yue, I came here on my own initiative to trigger the dragon vein. Uchiha Madara started the Fourth Ninja World War and wants to destroy the entire Ninja World..."

Naruto recounted what happened in their world with a serious expression.

"Uchiha Madara, he actually lived that long!"

Obito showed a surprised expression. He thought that Uchiha Madara had caused trouble in the Third Ninja World War in their world, which was disgusting enough.

I didn’t expect that in Uzumaki Naruto’s world, Uchiha Madara could actually start the Fourth Ninja World War.

Obito was thankful that there was Mu Yue in their world, otherwise there would have been a new Ninja World War more than ten years after the Third Ninja World War.

"Brother Mu Yue, I think our two worlds can unite and help each other eliminate the crisis."

Naruto continued.

If he were to travel back in time, in order to prevent history from becoming chaotic, Naruto would definitely not travel back in time to seek help.

Since the two sides are not from the same world, there are not too many concerns. Naruto thinks it would be great if the two worlds united.

Although they are not exactly the same, there are still many similarities, which means that the world where Mu Yue and others live can learn from the experience of Uzumaki Naruto's world.

"Traveling between worlds is not that simple."

Mu Yue shook his head. He guessed that Naruto had established a connection with the dragon veins of both worlds, which was why he was able to travel to them so accurately.

And it turns out that the crossing of dragon veins is not very stable.

Not much time had passed on Uzumaki Naruto's side, but he traveled through time and space and arrived directly on their side seven years later.

"Brother Muyue, it's okay if you can't get through. At least we can buy some more time to practice here."

In fact, Naruto’s main purpose of traveling through time was not to find help, but to practice.

Based on his previous experience, he could have at least one more month to practice.

With Mu Yue's guidance, his strength will definitely improve this month, and he will be able to better deal with the war then.

Naruto is not afraid of war, what he is afraid of is that he will not be able to protect his companions in the war.

"Brother Naruto, I don't like what you said. We must believe in the Immortal Mu Yue first, and then believe in him!"

Obito believes that Naruto's faith in Mu Yue Shengren has wavered.

"It should be possible to get through, but we can't bring too many people."

Mu Yue said under Obito's expectant gaze.

The Flying Thunder God Technique cannot travel across worlds, but he has Celebi.

Celebi's power of time and space has reached the mastery level. With Naruto as a living coordinate, she should be able to lead people through it.

It is impossible to achieve cooperation between the two worlds, but it is still okay to occasionally provide support.

"Brother Mu Yue, thank you so much, but since you don't need to bring anyone to my world, you can just teach me how to practice breathing techniques for a while."

Naruto smiled and thanked him.

Naruto’s idea is that if a large ninja army can be formed, the two worlds will join forces to defeat Uchiha Madara.

Just a few ninjas passing by doesn't mean much.

The moment he walked out of the barrier, Naruto sensed tens of thousands of enemies, some of whom had powerful chakra.

He couldn't let Mu Yue and a few ninjas risk their lives with him in the Fourth Ninja World War just because they were good people.

"Don't think too much. I'm actually quite experienced in dealing with Uchiha Madara."

Mu Yue said with a faint smile.

For him now, even Uchiha Madara in his prime can be killed with ease.

Only Six Paths Madara, who became the Jinchuriki of the Ten-Tails, was qualified to be his opponent.

What's more, the Uchiha Madara mentioned by Naruto is not even the real Uchiha Madara.

"Ahem, Naruto-sama, I have to remind you that Uchiha Madara was defeated by Mu Yue-sensei."

Obito coughed lightly and told the story of Mu Yue killing Uchiha Madara during the Third Ninja World War.

"As expected of Brother Mu Yue, you're amazing!"

Naruto sighed and said that without the scourge of Uchiha Madara, Mu Yue's world would be a better place than theirs.

"Don't worry, Naruto-sama. No one can be a match for Mu Yue-sensei."

Then Obito told Naruto about Mu Yue's record of defeating the elite of the four major ninja villages alone.

He saw what Naruto was thinking and was worried that they would be in danger, so he didn't want to let them go.

But there is absolutely no need to worry about this, as Mu Yue already has the strength to end the Ninja World War alone.

"That's troublesome. If you are injured in the battle, please retreat quickly!"

Naruto thanked Mu Yue, Obito and others solemnly, and silently kept this kindness in his heart.

If Mu Yue's world encounters a crisis one day, no matter how dangerous it is, Naruto will definitely come to help.

"Hello Naruto, could you please give me your hand?"

Seeing that the support arrangements had been finalized, Shisui stepped forward and spoke.

"you are?"

Naruto scratched his head with his left hand and offered his right hand to Shisui and asked.

"I am Uchiha Shisui, and there seems to be something of 'me' inside you."

Shisui grabbed Naruto's hand and showed an expression that said, "As expected."

The first time he saw Naruto, Shisui sensed his chakra in Naruto's body.

He and Naruto have never met, so the chakra in Naruto's body can only be left from Shisui in another world.

But according to information from Kakashi and the others, Naruto did not know the ninja named Shisui.

Shisui was very curious about what was going on with Naruto, but Naruto and Mu Yue were just talking about serious matters, so Shisui didn't interrupt.

"Ugh~"

As Shisui input chakra, Naruto suddenly made a vomiting gesture, and then a black crow came out of Naruto's mouth and appeared in everyone's sight.

As soon as the crow appeared, it immediately stood on Shisui's shoulder.

"Brother Naruto, how did you manage to hide the reserve food in your stomach?"

Obito's eyes widened, he didn't expect Naruto to spit out a living crow.

"what?"

Naruto scratched his head in confusion, a little bewildered by the situation.

"I remember now, Itachi gave it to me."

Naruto thought hard and finally found the source in a memory.

While searching for Sasuke, he met Uchiha Itachi, and was then cast under an illusion by the other party.

"The Uchiha Itachi who wiped out the Uchiha clan? He probably wants to use you to perform a genjutsu."

Hearing the name Itachi, Shisui frowned slightly, grabbed the crow on his shoulder, felt the Mangekyō Sharingan on the crow and said.

"This can't be 'your' Mangekyō Sharingan, Shisui."

Obito noticed something unusual about the crow's eyes.

"That should be it. It seems that the me in the other world was killed by Uchiha Itachi. He killed 'me' and took away 'my' eyes."

Shisui analyzed in a deep voice.

Listening to Shisui's words, Naruto hesitated to speak.

Uchiha Madara told him the truth about Uchiha Itachi, but Naruto was not sure whether the information Uchiha Madara said was true.

In the end, Naruto still didn't say anything.

Even if what Uchiha Madara said was true, then what Shisui said was not wrong. Uchiha Itachi did kill the Shisui of his world, and the Mangekyō Sharingan was indeed in Uchiha Itachi's hands.

"Shisui, you can try to transplant this eye. It should be possible to upgrade your left eye to the Eternal Mangekyō Sharingan."

Mu Yue spoke.

As an isotope from another world, the compatibility must be perfect, and there is almost no possibility of failure.

"Xiao Lin, could you please help me with the transplant surgery?"

Shisui nodded and looked at Nohara Rin and asked.

The opportunity to easily enhance his strength is right in front of him and naturally he cannot miss it. After becoming the Eternal Kaleidoscope, his pupil power will be even stronger.

"give it to me."

Nohara Lin agreed with a smile.

Obito looked at Shisui with envy, and he got an Eternal Mangekyo for free just by going out.

"By the way, Naruto-sama, our world is actually a different world. There shouldn't be Teacher Mu Yue and me in your world."

Obito then remembered that he forgot to mention the parallel world.

When Naruto first came, because they lacked intelligence, they both made misjudgments about each other, thinking they were in the same world but different time.

"I know this. There is indeed no Brother Mu Yue in our world, but there is actually someone like you, Obito, in our world. I asked about your news after I returned."

Naruto explained.

"Ah? I'm here!"

Obito showed a surprised expression, feeling something was wrong.

He wouldn't really die in obscurity in the Third Shinobi World War, would he?
