Nagato was slowly figuring out the Rinnegans 7 Path abilities on his own. The only ones he didn't were the ones he didn't use in the series that were particular to those eyes which were Tengai Shinsei and Limbo.. because he wasn't told about them.. because Madara didn't tell Obito about them(Madara isn't stupid, he kept his best techs a secret from even Obito)
