Something crossed my mind while reading some of threads and its about the scroll sasuke now has, I believe its the ultimate way of acquiring the rinnegan eye and reaching so6p level, these are my reasons.
1. Suigetsu read the scroll but when juugo woke up from been joked he was in a hurry to go see sasuke without letting juugo know anything.
2. Back when sasuke was injured for bee's attack juugo integrated his power into sasuke because he was the most compactable with the curse seal. So I believe he able senin mode too probably after learning how(3rd mountain motioned).
3. Kabuto statement of been more closer to so6p with addition of juugo and Karin's DNA +oro's.
4. The fact Karin herself is still in this manga without been major contributor besides having uzumaki DNA. She is in leaf village not a coincidence kishi.
5. The fact that orochimaru himself wants sasuke after already having karins and juugo DNA and body transferring jutsu. Meaning the perfect body that orochimaru needs to transcend into the next level is sasuke's DNA reap sharingan that's why he hasn't been able to go full sage mode. Sage mode+ sharingan+ uzumaki DNA.
6.. The other is oro's and danzo affiliation. Oro was the one that combined senju & sharingan on him if oro had believe that that was ultimate level or so6p power he would done it to himself. He most gone further into his experiments.
7. That fact that kabuto himself want sasuke after surpassing orochimaru. To the point that he didn't use senju DNA on himself
8. The fact sasuke needs orochimaru .
9. The fact that uzumaki DNA or clan are the catalyst to the equation of been so6p even madara recognizes them.
10. the fact that orochimaru scroll is something sasuke can study and preform
conclusion- I think the scoll is orochimaru result of reaching so6p level because he had all the opportunity to do the same thing to himself but choose to get a uchiha body after adding all the necessary DNA and jutsu together.
I want U guys let me know what you u think ?
