Just like how kurama had regained his full power, it changed nothing as a matter of fact it would make it even more better in the long run.
Sasuke plan all along had been to extract the nine tails from Naruto and only then could he spare him, that was however if both parties would ever agree to leave one another, not like they had choice in doing so though.
The world of revolution he sought did not involve the tailed beasts being used as weapons, they were an uncontrollable power shift and it has been proven countless time over that they can be utilized for means not intended.
It is also known that one cannot separate their tailed beast from themselves, especially since they had some sort of symbiotic nature with one another now.
And finally he understood so long as the nine tails exist, he would be forced to take extreme measures to kill Naruto as his life-force was undeniable strong.
That was when he decided to use the Gedo statue, he had seen it accomplish the feat of sealing the tailed beasts, though only temporarily,
And it was all connected to the rinnegan, but there was one issue, even after acquiring the rinnegan and gaining an increased chakra pool, it was not sufficient to summon the gedo statue, and so he tested the difference between the summoning of the rinnegan and four was his limit or he would pass out of exhaustion.
This augmented why Nagato was a monster even needing to sacrifice his life force upon all that.
Obito and madara were able to acquire the hashirama cells and his sage mode so that was understandable.
Him however used a different method and that was external chakra that was scattered by the tailed beasts in a restricted state being the susano and even then it touched on his life force, though only by a little, it was attributed to his control he managed to stop on time.
And just then the susano as if already reaching its limit slowly dissolved from the head down and just when it reached the torso eight massive purple chains shot out of the fog clouding the susano as it dissolved, these chains were aimed right into the planetary devastation restricting the remaining tailed beasts and then a swift pull took the first one into the fog surrounding the susano feet by now which quickly dissipated to reveal the head and shoulders of the gedo statue.
"naruto…" kurama said
"i know, I am on it" Naruto replied as he dashed right at the statue with one of his avatar while the others dashed towards sasuke who was now panting with two bleeding eyes, thorough strained mentally.
The two avatars that came at sasuke arrived in a flash with both of them throwing a punch at the uchiha who merely jumped off the stone platform and into the air free-falling
