Healing a broken leg takes a jubbi jin?? Wow what is this heresy. They can heal flesh wounds but not bone, because they're not the jubbi's jin.
I guess Tsunade became the Jubbi's Jin in order to heal lee's leg too, huh?
Smfh, Gai's body wasn't a simple broken leg or damaged organ, his
entire lower body was reduced to ash, the only thing that saved him was Naruto using
Hagoromo's Yang to save him and even then it didn't fully heal him.
If someone with the
Sage's body can't heal Gai what makes you think Tsunade and Sakura can ? The only person capable of doing so would be JuubiJins because they're the only ones able to regenerate entire limbs and bodies to their original state
