Starting at the Temple of Fire

The Eight Gates is essentially the Naruto version of the Demonic Disintegration Technique, except that the number of parts you disintegrate depends on which gates are opened. Might Guy's statement about self-imposed constraints and the inability to use it lightly stems from the fact that the Eight Gates is a self-destructive technique, and its violent power is difficult to control.

First of all, if you're looking for the Buddha Fruit to wreak havoc, you can forget about it. This book uses the Buddha Fruit more like a buff, and focuses on ninjutsu.

The title is sensationalist; it makes you think it's about creating all sorts of strange and wonderful techniques using the fruit of the Buddha. The results were all boring ninjutsu.

There's a problem with the timeline. How could Asuma have become a Guardian Ninja when the protagonist was 6 years old? The Nine-Tails' attack hadn't even started yet. At that time, Asuma would have been at most 13 years old.

For fire and earth, I thought of a dust explosion—that's pretty powerful! Adding wind jutsu would make it even better, and lightning could also be added. Earth is the dust, fire is the energy, wind disperses and restrains, and finally, lightning detonates.

The Buddha Fruit wasn't as impressive as I imagined; it was purely supportive, and it was some kind of ninjutsu/bloodline limit... Also, Orochimaru was killed off at the very beginning, which was ridiculous. It was actually pretty good, even if a bit inexplicable, but it was still quite novel compared to other fanfics. It was quite enjoyable... But then he was resurrected... Sigh, it felt like a rotten apple spoiling the whole bunch...

I think the best Naruto fanfiction follows the plot, which makes it more immersive. Adding personal changes, like a reincarnation of the Naruto world, makes it easier to understand. If the changes are too drastic, it's easy for the story to fall apart, and fewer readers will read it and abandon it after finishing the exciting parts (the vast majority of Naruto fanfiction).

Why was the ten-year-old protagonist so intimidated by Orochimaru's aura, developing a so-called inner demon? The description suggests the protagonist must immediately defeat Orochimaru to overcome this demon. How could Kakashi possibly accept this? Although the protagonist encountered an injured Orochimaru, it feels like an injured snake is far more dangerous.

Is this a Zoan-type? The increases in Strength and Constitution are barely noticeable; it's about the same as a normal person's, completely lacking the abnormal physique of a Zoan-type.

The Naruto world doesn't have Sea Kings like the One Piece world, so achieving the terrifying power of a Buddha might be impossible.
