I've read through chapter ten. It's neither great nor bad. It's an average fanfic. I'd say the biggest issue for the author is dialogue (Q&A) and descriptions (environment, characters, expressions, etc.). The author makes the core focus of the story the training, but it's all ambiguous. Some parts of the story should be cut out (filler). It's a decent 3/5. For Naruto fanfics, I recommend "The Outsider's Resolve," "The Blind Swordsman," and "The Gamer Ninja" as references that might help better your own story.

LIKEwhat I recomend is "naruto: the wind calamity" or "reborn in naruto with a tenseigan" both have slow progression and how more in depth into what it takes to become stronger tho wind calamity goes more into the process while the other is more the upper end of the process after reaching jonin.
