What did Naruto used to save them?

[V h o]

Footspeed/shunshin, Naruto doesn't have any teleportation jutsu anyway, at least that I know of Zzz

 

[bashkim]

Maybe he can used it. How knows. Naruto has access to the scroll of Hashirama with the forbidden jutus.

It might sound fan wagon to some, fact is Sasuke and Naruto are the fastest Shinobi among the villages unless Kaguya broke her seal. Instant? Omnipresent, omnipotent, omniconscient then dah
