Oh...it's going to be "that" type of impossible medical aid.
Wait...if Gaara is right there and they are traveling kilometers(a long distance mind you), why doesn't gaara just give sakura chakra? Or Naruto chakra?
And also, Uzumaki genetics is......giant chains? Karin took a whole through her mid and she's still ok?
I'm confused, I remember naruto's mother using Chains in the dream world, but I just thought that was here "technique" since every jinchuriki seemed to have one.
Guess the Uzamaki clan has giant chains.....that naruto can't use.....makes as much sense as anything else in the series at this point.
