so what did sasuke do?

[Vicen]

sasuke learnt genjutsu on his own....

No shit.:|You asked what he did during his time with Oro. He learned genjutsu and kenjutsu. No where did I imply Sasuke didn't teach himself. Lol

 

[ANiMUS]

Became adept at kenjutsu, genjutsu, Fuinjutsu, mastered the lightning element, advanced to itachi level shuriken jutsu, learned snake and summons, mastered advanced shape manipulation and chakra flow, became immune to most poisons, mastered the sharingan and fully mastered the cursemark seal. Sasuke's advancement is almost inhuman

-Kenjutsu
-Genjutsu

[Umari Senju]

He learned

-Kenjutsu
-Genjutsu
-Elemental manipulation
-Kirin
-Summoning Jutsu
-Body flicker/Shunshin
-Partial Curse seal transformation
-Shurikanjutsu
-immune to poision
-snake jutsu
-oral rebirth(after absorbing orochimaru)

The question is. Did Oro teach him these or did he just learn them himself under Orochi's watch?

Is this some kind of joke? Summonings are done through contracts. What the hell are you even blabbering about?

- Perfected Kenjutsu.
- He already excelled at Shuriken-jutsu and he took it a level above Itachi whilst his training with Orochimaru.
- Learned five variants of Raiton Manipulation. Eight if you count two additional uses of Nagashi and Chidori Spear.
- Greatly enhanced his speed.
- Perfected his control over Cursed Seal.
- Perfected 3 T Genjutsu.
- Learned to released Natural Energy as Orochimaru pointed out recently.

According to Kakashi and Sakura, his advancement was inhuman. And you are telling me he learned nothing? What did Naruto learn? Oh wait. Nothing.
