Naruto's strongest cheating system

So far, only the second and fourth generations of Konoha can really use the Hiraishinjutsu. Even the third generation of Naruto Sarutobi, who is known as a doctor of ninjutsu, does not know how to use the Hiraishinjutsu.

"Yes, Lord Three, this is indeed the Flying Thunder God technique, but I can't fully grasp it now. There will be a momentary pause at the moment of appearance, and the pause time will be determined according to the teleportation distance." Regarding the Flying Thunder God technique, Quan did not hide it. In fact, this time he used the Flying Thunder God technique to allow himself to use it openly.

You must know that the only place in Konoha that records the technique of Flying Thunder God is the Book of Seals. Therefore, if someone has learned the technique of Flying Thunder God, they must have stolen the Book of Seals, so Izumi needs to take this opportunity to explain it to Midai.

"Where did you learn the art of flying thunder god?"

"Three generations, after I left Konoha, I concealed my identity and entered the Bounty Association. There I received a mission to clear the country of merchants. I obtained the Flying Thunder God Jutsu and other ninjutsu scrolls from there." While talking, Quan took out the Flying Thunder God scroll.

The Third Hokage took the scroll and examined it carefully. Although he doesn't know how to use the Flying Thunder God Jutsu, he has seen this ninjutsu, so he can still judge the authenticity.After confirming that the scroll is real, the third Hokage is also very strange. As Konoha's ninjutsu, and it is still an S-level ninjutsu, how could it be left outside?

From the beginning to the end, the three generations never suspected that Izumi stole the Sealed Book. It was not that he believed in Izumi, but that Izumi did not have the strength. Anbu, who guarded the Sealed Book, was the best of the elite.

As for Uzumaki Naruto's stealing of the sealed book, it can only be said that it is necessary for the plot, otherwise, if Naruto alone is forbearing, isn't that a joke?
After thinking about it again and again, Izumi didn't say that he stole the sealed book, maybe he didn't even know the existence of the sealed book, so Sandai Hokage didn't continue to delve into this matter.

"Quan, in the future, if someone asks you how you learned the art of flying the thunder god, just say that I let you learn it, and don't let anyone tell you about what you told me today."

"My lord, I have already told others about this. After returning to Konoha, I taught Hinata the Flying Thunder God. I think this ninjutsu is very useful, so..."

Of course Quan didn't give Hinata the Flying Thunder God Art because there was no time at all, but if he didn't say that and taught Hinata in the future, there would definitely be trouble.

Hearing what Quan said, the Three Hokages were slightly taken aback. He really didn't expect that Quan would teach this extremely important ninjutsu to others in just one day after he came back. Fortunately, he taught it to the eldest lady of the Hinata Hinata Hinata clan. If it was taught to the spies, wouldn't it be a piece of information given to the other party for nothing?

"Okay, since you've already taught it, let's teach it. However, Izumi, you have to remember that you must never do this in the future. For you, S-level ninjutsu is still too far away. Flying Thunder God does not require too much chakra, and most S-level ninjutsu requires a huge amount of chakra. If you try it casually, problems will easily occur."
