Naruto's plan was to transplant a Sasuke Mangekyō Sharingan, and similarly, to transplant a Mangekyou Sharingan cultivated using Sasuke's genes into Mangekyō Sharingan. As for later changes, Naruto still had some ideas.
It's important to know that in the original story, only Sasuke awakened the Eternal Mangekyō Sharingan by transplanting Itachi's eyes. Furthermore, the Eternal Mangekyō Sharingan, being a superior form of the Mangekyō Sharingan, possesses abilities distinct from the Mangekyō Sharingan.
Sasuke's Mangekyō Sharingan granted him abilities like Amaterasu and Kagutsuchi. As for Susanoo, almost anyone who has awakened the Mangekyō Sharingan can use it.
Itachi's Mangekyō Sharingan grants him the Genjutsu- type Tsukuyomi and the ability Amaterasu.
After Sasuke awakened the Eternal Mangekyō Sharingan, his overall strength increased significantly. Even Madara Uchiha at the time referred to Sasuke's Eternal Mangekyō Sharingan as " Straight Tomoe." Naruto speculated that this might be a special name for the Eternal Mangekyō Sharingan.
In Naruto's thoughts, the first thing he thought of was transplanting Itachi's Mangekyō Sharingan, which was cultivated with Fugaku's genes, into him. This might further enhance Itachi's Genjutsu abilities.
It's important to know that Itachi's Genjutsu abilities are quite strong. If it weren't for Shisui's ridiculously overpowered Kotoamatsukami, Itachi's Mangekyō Sharingan Genjutsu abilities would definitely be the strongest.
Furthermore, Itachi's control over that bastard Obito was far too obvious. This is why Obito didn't dare to show himself easily when Itachi was still alive. Otherwise, a single Genjutsu would have left Obito completely dumbfounded.
It's important to understand that even Kabuto Yakushi, who had activated Sage Mode, couldn't withstand Itachi's mastery of Genjutsu. How much more so for Obito, a mere mortal, whose resistance to Genjutsu was practically nonexistent.
Even Naruto can only unleash a massive Genjutsu by combining various Ninjutsu, while Itachi can do it with just a glare. That's incredibly underhanded. Isn't that underhanded? One glare and he's dragged you into the Tsukuyomi Space for torture.
If Naruto could create such a powerful Genjutsu, he would have been killed by Obito long ago.
He could even imagine that if he had Itachi's powerful Genjutsu abilities, he would Obito into a Genjutsu space and play on a loop the scene of Kakashi piercing Chidori with Obito. This was simply inhumanly vicious.
"Let's go, Sasuke."
"What are you going to do?"
After hearing Naruto's words, Sasuke stopped teasing the little Blood Monkey.
"Go, I'll find a way to awaken your Mangekyō Sharingan."
Naruto's words filled Sasuke with excitement. Was it finally going to be his turn? That was the Mangekyō Sharingan! The thought of possessing it himself and becoming a powerful ninja like his father and brother filled Sasuke with fervor.
Naruto felt somewhat uncomfortable looking at the incredibly passionate Sasuke. Was it because of him?
Why is Sasuke so hot-blooded?
In the Uchiha mansion in Konoha, Naruto told Fugaku and Itachi what he wanted to do. During this time, their expressions changed back and forth, sometimes excited, sometimes shocked, and sometimes helpless. But as the saying goes, sir, times have changed, and changing expressions are no longer acceptable.
After pondering for a long time, Fugaku finally asked:
" Naruto, what are the chances of Eternal Mangekyō Sharingan you mentioned?"
Fugaku's words made Sasuke and Itachi look at Naruto as well, since this was the most crucial question. In the entire history of the Uchiha, only Madara Uchiha had successfully awakened the Eternal Mangekyō Sharingan Eternal Mangekyō Sharingan Eternal Mangekyō Sharingan. There were no other recorded cases of anyone else achieving this, which undoubtedly demonstrates its difficulty; otherwise, the entire Shinobi World would have belonged to the Uchiha clan long ago.
Naruto glanced at Sasuke and Itachi, thought carefully for a moment, and then gave a precise figure.
"If it's Sasuke, I'd bet on it. As for Itachi, there's probably a 50% chance he can awaken the Eternal Mangekyō Sharingan."
"Hiss~"
Naruto's words caused the people present to gasp in shock. They hadn't expected that Sasuke would have the highest probability of success, even though Sasuke hadn't even awakened his Mangekyō Sharingan yet.
It's not surprising that people reacted this way. After all, Sasuke is a man in the Hokage world; how could he not have some protagonist's aura?
Fugaku stroked his chin, pondering Naruto's suggestion. The probability of success was already quite high, but he also had some worries. After all, Naruto was his child, and if something really happened to him, he would be the one who felt the most pain. However, the opportunity to lead the Uchiha to great heights and bring glory to their ancestors was right in front of him. If he didn't seize it, who knew when the next opportunity would come?
With that thought in mind, Fugaku gritted his teeth.
"Okay, I agree, Naruto."
Upon seeing Fugaku's agreement, Sasuke's eyes shone with excitement. He was about to become stronger; how could he not be overjoyed?
As for the other plan that Naruto proposed, Fugaku also agreed.
That is, select some highly talented members of the clan, and after they awaken the Mangekyō Sharingan, start cultivating Mangekyō Sharingan with their genes. Although it may not be possible to create the Eternal Mangekyō Sharingan, it is still a good alternative to the Mangekyō Sharingan.
After all, everyone in the Shinobi World is far too familiar with the plug-and -Sharingan. That's why the Uchiha Clan destroyed the eyes of their deceased members; otherwise, wouldn't it be terrible if there were copy masters and Konoha leaders everywhere?
What if their other families use special secret methods to preserve the stolen Sharingan and pass it on to the next generation? Wouldn't that be a complete disaster? One eye can be passed down through Third Hokage; even if the person dies, the eye remains?
"Then, how do we awaken Sasuke's Mangekyō Sharingan?"
At this moment, Itachi asked the question that Sasuke had always wanted to ask.
Naruto smiled, but Sasuke, upon seeing Naruto's smile, nervously swallowed, feeling a sense of foreboding.
"It's simple. All you need to do is help me maintain the illusion with Fugaku."
"Oh? It's that simple?"
"Yes, it's that simple."
As Naruto said this, he gave a meaningful smile.
Just as the group was arguing, a spatial Uzumaki suddenly appeared in front of them, from which several pale arms reached out and grabbed at them. This sudden turn of events startled everyone, but fortunately, they were all powerful ninjas who quickly dodged and entered battle mode.
