Naruto's strongest cheating system

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

"Yes, Lord Three, this is indeed the technique of Flying Thunder God, 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 distance of the teleportation." For Flying Thunder God Quan didn't hide the fact that he used the Flying Thunder God technique this time so that he could 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, so 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 reconcile with him. Sandai explained, otherwise, it would be bad if Danzang knew about it first.

"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, where I received a mission to clear the country of merchants. I obtained the Flying Thunder God Technique and some other ninjutsu scrolls from there. "While speaking, Quan took out the scroll of Flying Thunder God.

Third Hokage took over 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 Quan stole the sealed book. It was not because he believed in Quan, but because he believed that Quan did not have the strength. The Anbu who guarded the sealed book was the best of the best. A child whose strength is only that of Chunin, it is impossible for him to steal the sealed book.

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 Quan's words, the Three Hokages were taken aback for a moment. He really didn't expect Quan to teach this extremely important ninjutsu to others in just one day after he came back. Miss, if you teach this to a spy, wouldn't it be a free gift to the other party?

"Okay, since you have 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. The chakra needed to fly Thunder God It’s not too much, and the chakra required by most S-rank ninjutsu is very huge, if you try it casually, it is easy to cause problems.”
