Looking for a specific Time Travel/Reincarnation Fic

I read it a few years back, it involved Naruto either using a seal or dying and in the first or second chapter receiving the offer to go back in time by Hagoromo, he accepts this offer and wakes up with an implanted hashirama cell arm during or between the 3rd shinobi war and academy eras.

I don't know any details past that but I hope this is enough for people to try and find it.
