Yan's expectations for Sasuke were simple: train hard and become stronger.
As for the three great sacred lands and Sage Mode, it was better not to mess with them.
With Sasuke's personality, if he went to one of the three great sacred lands, there was no telling when he might turn himself into a stone statue.
Wouldn't it be better to work hard, grow stronger, and wait for the Sage of Six Paths to favor him?
Yan believed the Sage of Six Paths would value Sasuke. If Sasuke got lucky, he might even get a free pair of Eternal Eyes or something.
As for the even higher-level Rinnegan, that would depend on whether the Sage of Six Paths was willing to part with his own power.
He had casually awakened Naruto's Sage Body and given Naruto and Sasuke a Tomoe Rinnegan each. If anyone said the Sage of Six Paths had no way to turn a three-tomoe Sharingan into a Mangekyō Sharingan or Eternal Eye, Yan wouldn't believe it even if they beat him to death.
It might sound absurd if it happened to anyone else, but for the Sage of Six Paths, it was no difficult task.
As long as he was willing to give up some of his power, anything was possible.
"Raikage, after some time, I'll have Jiraiya take Naruto to Kumogakure. His special training will have to trouble Killer B and your village."
Naruto was different from Sasuke. Sasuke only needed to grow according to the plan.
But if that unlucky kid was put under too much pressure, his mentality would suffer.
Naruto, on the other hand, would not have that problem. Under the influence of Asura's chakra, Naruto was like an indestructible cockroach.
That applied to both his body and his mind.
Without Asura's chakra
