I can overlook the plot being the creation of a Naruto fanboy, so long as said plot is original and plays a prominent role on the story. This should be a given, but unfortunately that is not the case.
Rather than focusing on how the abilities the protagonist gains interact and are perceived in the world he finds himself in, the author instead spends far too much time describing the history of the various techniques which, even in this story, take place in a fictional world. This badly distorts the story's pacing and is entirely unneeded. Someone reading this story because they like Naruto will already know much of this information, and those readers who simply want to enjoy the story don't care.
The protagonist's goals also create a barrier that prevents the story from developing. Wanting vengeance against those who wrong him is fairly standard and easy to work with. Focusing on returning home, however, prevents the protagonist from making real, meaningful connections with other characters. Even when he recognizes someone as a friend, it always seems like a brittle, temporary friendship, as the protagonist intends to leave his current world entirely.
In summation, this is a story that fails to properly utilize an already-established cultivation system drawn directly from another work. It is written in a manner closer to an encyclopedia or wiki than an original tale. The character development is shallow and hindered by the protagonist's established goals.
