Author messed up by making MC 3yr old. So many old geezer changing entire war plan 1hr before it because of his stupidly childish "advise" that no genius uzumaki could came up? Also, changing entire political and cultural tradition of their village because mc said they need varity of clan? Yea, this is clearly written by someone who've never work a single day in real world.
A silly imagination of childish fantasy.
