Regarding the controversy about Izanagi, some readers think that Izanagi does not need a kaleidoscope, but only three magatama.
But in the 44th episode of the Great Ninja War, Uchiha Itachi gave a clear explanation to Izanagi and Izanami.
Izanagi has two characteristics:
One is that it requires a kaleidoscope.
Second, its function is to distort reality.
First, at a certain period, the Uchiha clan had a kaleidoscope explosion, and they invented the Izanagi technique.
The key point is the second one. According to the records of the Uchiha clan, this technique can not only resurrect oneself, but can even resurrect all clan members after they are ambushed.
The perfect pupil technique that can transform all adverse factors into dreams. To put it bluntly, Izanagi is really the most awesome pupil technique in all Hokage.
Of course, it is an old tradition for Naruto to take advantage of settings. For example, in Boruto, Sasuke never thought of using this technique. Otherwise, Naruto would have just died in heavy particle mode, and Sasuke could have distorted this reality and resurrected Naruto.
This technique has too many uses
But it is because this technique is so awesome that I have been struggling with settings.
Moreover, this technique is so awesome that it will double the already arrogant character of the Uchiha clan.
So the Uchiha clan began to use Izanagi to fight among themselves, and it was like a matryoshka doll fighting among themselves.
In order to prevent the Uchiha clan from being wiped out by civil war, Uchiha established Izanami, a technique to restrain Izanagi.
Izanami is a pupil technique that can be activated by setting up several fragments of reality and only needing to complete the settings without making eye contact.
Its effect is to trap people in these cyclical fragments forever, forever trapped in reincarnation.
Unless you see your "original heart", I put this in quotation marks.
Because there is no specific explanation of what the original intention of a Chinese practitioner is, I suspect that this original intention is actually defined by the practitioner.
This is a more terrifying illusion than other gods, turning reality into a dream. As long as your "original heart" does not become what the caster wants, you will never be able to get out.
Another controversy is the timeline. To be honest, Naruto wants a rigorous timeline.
Totally impossible.
Naruto's timeline is notoriously messy.
To be honest, there is no point in you and me arguing about the timeline.
Do you know why?
Because the official later issued a book of formations, which recorded that the second generation died in World War II, and the third generation came to power at the age of forty.
Then the entire Naruto timeline exploded in an instant.
Therefore, the first thing the author does when writing a Naruto fanfic is to figure out the timeline.
So cherish every Naruto fanfic you read, because you don't know how much information its author has researched in order to sort out the timeline.
And there is no need for a too strict timeline. I am playing the role of the Hyuga clan leader, and the younger version of Hinata Hizashi is the clan leader. Obviously, the latter has a more sense of immersion, because this is the original character, and this arrangement also saves a lot of trouble.

The same goes for Uchiha Fugaku, as long as there are generally no problems
