ignore the classification, it does not reflect what I really think of the story.
the story for me was very good, until chapter 22 where the author decided to send the MC to HOTD!
in this story the MC can basically be counted as a ghost of the story. He is immortal and very OP to the naruto world, he has the lineage of uchiha, senju, uzumaki and yuki (Kiri ice user). it grows and with its system it becomes very strong in a short time. as time goes by, the MC becomes a man who roams the world and occasionally interferes with one thing or another, mainly training some characters, like he trained madara, hashirama, tobirama, myth and sarutobi (although he trained sarutobi for just a week) .
Mc basically watches the history of the world without interfering too much, it may seem that he is trying to follow the canon, but this is not the case considering that he ensured that the ties between hashirama and madara do not break and they do not fight.
during his adolescence he met a girl who fell in love and almost married, but she was killed during a trap they fell into, from there he never fell in love with another woman for almost 100 years, taking into account that he interfered in the fight tsunade, jiraya and orochimaru against hanzo.
and then, after saving the three from hanzo, he is sent to the world of HOTD and then goes back to being a horny teenager as soon as he meets Saeko! seriously, it made it look like he didn't live more than 100 years (taking into account his past life).
it was such a big break in the mood that I don't even know if I want to continue reading more, it was supposed to be a naruto fanfic, not a multiverse!
