I don't understand why everyone whines.. Compared to the tons of trash ffs this one is excellent, while its not masterpiece you would like to read again several times it is still very good. Talks about harem... Well i don't know what author will eventualy write, but at least until now I don't find Naruto's interaction with female characters irritating, he is not like MCs going after every female in story, actualy he don't go after them at all. Till now there are only 3~4 potential love interests(Yamato, Robin, Karin and maybe Hinata) and its not like naruto goes after them like hornydog, he meets them by accident. As for being boring.. If you prefer cold face-slapping, ruthless MC or dark MC then yes its boring(naruto doesnt start large scale slauthers just over minor upset, at most kills person responsible for matter without being domineering)

To be honest, it was quite good until last part(about Qin), but its illness of most chinese ffs. As for story itself only con for me that MC didn't grow himself, he got some inf Stones and their energy as kind of equipment and learned magic in marvel but used only power of space and reality, smtimes mind and time as for magic only space door, shield magic and mirror space... Which makes MC's setting somewhat bland, but he can summon heroic Spirits so it makes up for lack of cool moves.
