Naruto: Two opponents versus Naruto, Konoha panics!

Uchiha Izuna: It was left by my older brother.

Uchiha Izuna: This part should refer to the Eternal Mangekyou Sharingan.

Tobirama Senju: "Has the Eternal Kaleidoscope ever appeared in your clan's history?"

Uchiha Izuna: No.

Uchiha Izuna: The conditions for activation are both harsh and easy to meet.

Uchiha Izuna: To evolve the Mangekyou Sharingan into the Eternal Mangekyou Sharingan, a transplant is required... and perhaps there's an additional condition: close relatives?

Uchiha Izuna: Before I died, I asked my older brother to transplant my eyes, and he agreed... which resulted in the Mangekyou Sharingan evolving!

Uchiha Izuna: Due to years of fighting, overuse of the Mangekyou Sharingan is inevitable. My older brother's eyesight is worse than mine, so I can use my eyes for a longer time than he can.

P.S.: To make a slight change, the more chronologically accurate scenario is: after Izuna Uchiha's death, there was another great battle, which resulted in defeat, Konoha was rebuilt, and Madara Uchiha deciphered the stone tablet, learning of the existence of the Eternal Mangekyou Sharingan (Black Zetsu). Alternatively, it could be that before the great battle, he deciphered the stone tablet to find a way to save his younger brother.

Ino Yamanaka: "My godfather..."

Uchiha Izuna: It's alright. When I heard my older brother tell me about it, my last breath left me, and I felt relieved.

In the Pure Land, Madara Uchiha remained silent.

At that moment, Tobirama Senju suddenly said:

"No, besides family and friends, they all have to possess the Mangekyou Sharingan, and there might be another condition!"

Uchiha Izuna immediately understood.

Uchiha Izuna: You mean... my brother just said too, the reincarnation of Indra, the eldest son of the Sage of Six Paths?!

Tobirama Senju: "That's right!"

Tobirama Senju: "I understand now. My elder brother is the reincarnation of the Sage of Six Paths' child, right?"

If it's the eldest son, then there must be others after him.

Moreover, there is a high probability that they are the ancestors of the immortal beings.

Tobirama Senju: "Furthermore, my brother and Naruto are the same reincarnation!"

Tobirama Senju: "No wonder I found it strange before... If that's really the case, then it seems quite normal for Naruto in our world to be like this."

Tobirama Senju: "Also, Naruto with black frames said he hates Sasuke... Sasuke might be talking in his sleep... That makes sense!"

"Eternal... Mangekyou Sharingan."

Naruto murmured something.

"If it's family or friends... no, the Uchiha clan rarely intermarries with outsiders, so maybe you and Sasuke could give it a try in the future."

"Also, there's that Uchiha Itachi."

"Three pairs of eyes... will eventually match."

"But there's still one problem."

"The Uchiha clan, descendants of Indra, the eldest son of the Sage of Six Paths."

[As Naruto was thinking, Izumi suddenly continued.]

"My eldest son... fought a great battle with my second son, Asura... Indra was defeated... After their deaths, the battle did not end... but continued through reincarnation... continuing the fateful battle..."

【boom--】

Naruto's entire body trembled.

This is it!!!

[Izumi's wife's interpretation was even more hesitant, indicating that this part of the story was not yet complete, but this general outline of the events immediately cleared up many of Naruto's doubts.]

[Talking incoherently!!!]

The Uzumaki and Senju clans are distant relatives, so it's highly likely they are both descendants of Ashura, the second son of the Sage of Six Paths.

[The immortal body... the immortal eye... interact with each other, creating the myriad phenomena of the universe!]

Madara Uchiha is the reincarnation of Indra, which may be why he awakened the Eternal Mangekyou Sharingan... He orchestrated the great war and obtained the Sage Body... Hashirama Senju, the First Hokage... The reincarnation of Ashura!

[Both were reincarnated, both possessing chakra... The fusion of these two chakra streams is equivalent to perfectly inheriting the Sage of Six Paths' abilities... the Rinnegan!]

Madara Uchiha possesses the Rinnegan!

Naruto's forehead was covered in a thin layer of cold sweat, and his back was also soaked with sweat.

In just a few breaths, he seemed to have deduced a tremendous secret.

"So it seems... I'm like Hashirama Senju, a reincarnation of Ashura... rambling... the chakra in my mind... Ashura? Foolish, naive, and overly kind-hearted... Hashirama Senju's thoughts... make sense!"

[“So, since the previous Indra, namely Uchiha Madara, obtained the All-Encompassing Nature... will he be reincarnated again?”]

["If it's a reincarnation... then Madara Uchiha is definitely dead now, and Obito Uchiha will become his successor... Sasuke is very likely the reincarnation of this generation... No wonder I felt he deserved to be beaten, it turns out it's because of a fateful battle..."]

But then a new problem arose.

Why did Madara Uchiha orchestrate this?

【Ideological differences? Or an inevitable war?】

[Or perhaps... something is guiding Madara Uchiha to do all this?]

Black Zetsu: "..."

That's not interesting.

Really!

Naruto with black-rimmed glasses, this is really boring!!

[Logically speaking, if Madara Uchiha really wanted to conduct experiments, he could have simply approached Hashirama Senju... Hashirama even agreed to have his body studied after his death... just like the respected cadaver teacher.]

[“Then he orchestrated the Uchiha Obito incident... What he's about to do is definitely a major event, and it's likely to be met with disapproval from most people... Even Hashirama Senju would try to stop him.”]

[It's possible that Tobirama Senju targeted the Uchiha clan... Madara Uchiha asked him, and Hashirama Senju agreed, but Tobirama Senju refused.]

Naruto felt a bit confused, but countless brilliant ideas kept flashing through his mind.

It seems as if an invisible hand is preventing the truth from emerging.

[A series of obstacles were set up.]

"Let's put the eternal kaleidoscope thing aside for now."

"Madara Uchiha and his younger brother Izuna Uchiha were the mainstays of the Uchiha clan."

"They have been fighting the Senju clan for many years."

"There is no record of blindness... As long as the Mangekyou Sharingan is not overused, it can be used for a long time."

"Just like Itachi Uchiha and Obito Uchiha."

Naruto took a deep breath, trying to calm his agitated heart, but Sasuke's image flashed into his mind at just the right moment.

【If it were Sasuke…】

He shook his head.

There's always a way out, even if Izumi's wife can't awaken the Eternal Mangekyou Sharingan in the future because she doesn't have Indra's chakra.

At that time, I was also able to convert a considerable amount of highly vital chakra through my delirium... plus the great fox's golden chakra, and if all else failed, I could personally study Hashirama Senju's cells...

At this point, Izumi began to explain in detail the fated battle between Indra and Asura.

Naruto suddenly had an idea.

[“Since Madara Uchiha can manifest all things in the universe, can I also manifest all things in the universe?”]

[“If Sasuke awakens the Mangekyou Sharingan and then obtains Itachi Uchiha's Mangekyou Sharingan, awakening the Eternal Mangekyou Sharingan will be a certainty.”]

[“So…I’m transplanting Sasuke’s eyes?”]

[Or perhaps, we could transplant cells (tissue cultures) left behind by Madara Uchiha and Hashirama Senju?]

"The myriad phenomena of the universe... perhaps it refers to obtaining and inheriting the true, complete power of the Sage of Six Paths?"

【"Otsutsuki?"】

Never heard of it before...but...

Could it be related to this surname?

Just then, Quan's explanation paused for a moment, then continued:

【"Infinite Tsukuyomi..."】
