Review Detail of David_Drake in Naruto: The Strongest Kenjutsu User

It's a SI - OC fic of Naruto. The writing has little mistakes and the updates are frequent. You have a MC who is born right around the death of the fourth hokage. We are 'told' that he practiced to the point where he surpasses Itachi's strength at the same age. With that out of the way, lets bring up the things I dislike. His breathing technique can be consider the ultimate way to power up for the MC. And lets not forget that at 6yrs old the MC can destroy one of the swordmasters in the village with only the second rank in his sword technique. These two things are what tells me that the author is too caught up in his OP fantasy and fails to define the process/training the MC has to go through to becoming god tier. This causes massive plot holes that shouldn't be there like: when can you join Anbu, how can a Chuunin Taijutsu Specialist teach B Rank Jutsu, and is talking to the Hokage on equal terms at age 6 acceptable? On top of this the author frequently contradicts his statements in the same chapter. It makes it clear that the only research he has done was on the names of techniques/places but not the underlining functions of ninja society. Leaving things unaccounted for and creating this kind of crack fic. And plus the time skip destroyed what little it had going for it.
