Sage mode training.

Add that to learn sage mode you have to talk to The sage mode Ncp(which are different types)

Toad sage mode: Naruto clan and Jiyaiya Teleported Mount Myboboku to study under toads as Jiraiya and Naruto have done.


Snake Sage mode: Kabuto and Orochimaru clan Teleported to Ryuchi cave to study under snakes from the Ryūchi Cave where Orochimaru and Kabuto Yakushi learnt it.

Slug sage mode: I don't know about that yet

Thanks,
