Naruto: Butterfly From The Past

It's the same old transmigration/reincarnation into Naruto world fanfic. Just that the timeline is a little too far from the OG plot. Ofcourse he's going to get involved in the plot later on, but he's in a time period which he has no idea about. Time period of his birth or rebirth if you may, is 300 years give or take after the death of both Indra and Ashura. I need to mention it beforehand, system won't be MC's 'caretaker'. But only be a treasured resource. He'll be the source responsible for his growth himself. I own nothing more than my OC. I don't think I need to say something like that when it is written in the Fanfic category, but still....
