your medical ninjutsu is only strong enough to differ death to what essentially amounts to a meaningless period of time... it's pathetic compared to what hashirama senju was able to accomplish... he could heal wounds without even weaving a single sign.. in every jutsu he attempted he was in a class by himself, everyone viewed him as the ultimate shinobi... and i once fought a battle with him putting my own life on the line compared to that... this is nothing
