No bruh, I believe I forgot the part where Hashi's cells significantly reduce the time to activate KA until you brought the scan. I was originally under the assumption that it didn't matter but that foolish thinking from here because when aren't Hashi's cells ever relevant.Something tells me you already knew the answer to the question you gave me? But yeah, hashi genes is ridiculous, it's hard to believe he doesn't have the life force possessed in uzumaki clan (but then again he has ashura chakra so perhaps he does? ). Lol fix uchiha blindness, lmao for a tongue cheek moment i wouldn't be shocked that his jesus genes can allow lee to use ninjutsu.
Hashirama has a big life force. I don't see why he wouldn't have a large life force. His clan is the ancestral clan of the Uzumaki who lave longevity genes and are able to house the Bijuu. He is Ashura's transmigrant and that Yang Seal is shown to revive/restore. Perhaps even extending his life. You do know that Hashirama lived a long time right, long enough to battle with Kakuzu and send his ass packing.
