Having won the lottery, Izayoi did not immediately rush to feel the changes brought by the Sennin's Eye.
He first organized his thoughts and focused on treating Sasuke Uchiha.
Looking at Sasuke's eyes, which were a bit swollen from the days of suffering, Izayoi felt a bit of pity.
The world of Naruto was full of tragic orphans, but the ones who had happy families before losing everything stood out in Izayoi's memory as just two.
One was Nagato, the other was Sasuke Uchiha.
But compared to Nagato, who had Yahiko, Konan, and Jiraiya, Sasuke was far more tragic, having been manipulated by Itachi Uchiha from the beginning.
From the start, he had either walked the path of revenge or, after learning the truth, was immediately crushed by the one person he considered his most trusted companion.
Afterward, to atone for his sins, Sasuke would spend years gathering intelligence about the Otsutsuki Clan, barely returning home.
If Izayoi didn't intervene in Sasuke's fate, Sasuke would end up even more tragic than in the original story.
After all, before graduation, Sasuke was the top student in his class.
But now, Izayoi was the top student, with Hinata in second place, and Sasuke was left fighting for third.
After graduation, he would continue to face setbacks, watching Naruto, the so-called underdog, surpass him at breakneck speed.
"Should I give him a hand?" Izayoi thought to himself.
At this moment, Sasuke, who had just fainted, was waking up.
Looking at the small scar on his chest that had healed, Sasuke involuntarily recalled the battle they had just fought.
Whether it was taijutsu or ninjutsu, he was no match for Izayoi.
The consecutive attacks and the foundation supporting that speed were on an entirely different level.
Moreover, the scar on his chest and the green light he had seen when he opened his eyes seemed to indicate that Izayoi had medical ninjutsu.
Thinking about this, Sasuke immediately felt a sense of defeat.
"I lost," Sasuke admitted.
Sasuke wasn't someone who couldn't accept defeat. Just like Naruto, he didn't despise Izayoi.
Although it had been an unregulated fight, Sasuke had suddenly released ninjutsu, which had been a very dangerous move.
So, Sasuke straightforwardly admitted his defeat.
"I was lucky to win," Izayoi said as he patted Sasuke's shoulder, genuinely praising him. "You're pretty strong. I thought I was the only one who knew the Five Elements Techniques, but it turns out you do too. You truly are a genius of the Uchiha Clan."
Izayoi stood up and extended his hand to Sasuke. "I had the upper hand today. Let's have another match next time."
Looking at Izayoi, who had no arrogance and even praised him, Sasuke felt a warmth spread in his heart.
Feeling acknowledged, Sasuke smiled for the first time since waking up. He grasped Izayoi's hand and said, "Next time, I won't lose!"
Izayoi pulled Sasuke up, giving him a thumbs-up. "Then you better train hard. I'm pretty strong."
"Just wait and see!" Sasuke said with renewed determination, performing the Seal of Reconciliation.
This scene was also reflected in a transparent crystal ball.
Seeing this, Sarutobi Hiruzen, who was leisurely smoking his pipe, couldn't help but smile with approval. "The new leaves are beginning to sprout."
At this moment, Sasuke Uchiha was in his most vulnerable state.
To prevent him from taking his own life and to allow Itachi to continue his spy mission, Sarutobi Hiruzen had promised Itachi that he would look after Sasuke.
The Anbu had long been observing Sasuke from a distance.
As the two left the ninja school and headed for the abandoned training ground, the news quickly reached Sarutobi Hiruzen's ears.
Fortunately, Izayoi hadn't spoken to himself or acted in an exaggerated or bizarre manner when he was stunned. His behavior had been calm, which prevented any suspicion from rising.
Sarutobi Hiruzen was no stranger to Izayoi.
This generation's new students were particularly special, with the Nine-Tails Jinchuriki and the heirs of various major ninja clans in the same class.
Izayoi, who had surpassed them all to become the top student, had already caught Sarutobi Hiruzen's attention.
Through the year of observation, Sarutobi Hiruzen had found that Izayoi had already mastered the Shadow Clone Technique and low-level Wind Style, and often trained with Hinata, the heir of the Hyuga clan, in the abandoned training ground.
Every era had its exceptional civilian geniuses.
Like Orochimaru, Minato Namikaze, and even the lesser-known Kabuto...
Even Kakashi Hatake could be considered a civilian genius, since he didn't have a bloodline limit.
Compared to these civilian geniuses, Izayoi wasn't that extraordinary, nor could he be considered number one.
However, his talent was enough to warrant special training.
With proper guidance, Izayoi could become an elite shinobi, a versatile top-tier ninja. If he learned forbidden techniques, he could even become a trump card in the village.
Thus, Izayoi had been on Sarutobi Hiruzen's watchlist for quite some time.
...
After parting with Sasuke, Izayoi made his way home while summoning the translucent screen visible only to him.
At the top of his talent list, the Otsutsuki Bloodline (Red) was followed by the Sennin's Eye (Red).
The appearance of this entry hadn't brought any obvious changes to Izayoi just yet.
However, Izayoi was certain that there were unseen changes occurring within his body.
The Sennin's Eye was not the same as the true Sennin's Eye (Rinnegan). It was a unique ability of Otsutsuki Indra, inherited from the Six Paths Sage's Yin Release chakra and spiritual energy, representing the ultimate in Yin power.
What's more, this entry wasn't Indra's chakra, meaning the ultimate Yin power that Izayoi had obtained wasn't imbued with Indra's will, but was a pure Yin energy separated from Otsutsuki Kaguya.
The reincarnation body still needed to gain recognition or gradually unlock this power through growth and talent.
But Izayoi didn't need that. He would grow stronger quickly, just like Otsutsuki Indra.
In the coming years, Izayoi's spiritual energy and Yin Release chakra would experience explosive growth.
'Right now, I should be considered the second Otsutsuki Indra,' Izayoi thought with a smile in his heart.
If he could see Indra's talent entry, he would be sure that his entry wouldn't have the Uchiha bloodline but would instead be the high-level Otsutsuki Bloodline.
It was this bloodline that allowed him to possess infinite ocular power without needing to exchange eyes.
Izayoi didn't need to guess. He knew that with his current ability to use the Five Elements Techniques without hand seals, his Otsutsuki Bloodline would definitely be at the red level.
As for what lay beyond the red level, that seemed impossible. Otherwise, the reincarnation body of Indra's chakra wouldn't require two extremes to merge to awaken the Rinnegan—it could simply evolve from the Sharingan, just like Kaguya Otsutsuki did.
Right now, Izayoi was essentially the second Otsutsuki Indra.
Only by further elevating his Otsutsuki bloodline would he become the second Otsutsuki Kaguya and Otsutsuki Hagoromo.
