Hello everyone, I am Xiao Huihui. In the anime "Naruto", there are many powerful ninjutsu, and Naruto's successfully researched Fengdan·Spiral Shuriken is one of the more powerful ones. This technique allows Naruto to have the strength close to the shadow level directly, and makes Naruto from a novice ninja to a real powerful ninja. In the anime, no matter what ninjutsu he has learned, Naruto will give it to his apprentice Konoha Maru as soon as possible. So, why did Naruto no longer pass on his spiral shuriken to Konohamaru after Konoha maru learned the spiral pill? Because of this, he can't learn.
When Naruto was learning Helix Pill, but after learning for a while, Kishimoto will describe Naruto Helix Pill very deeply. Naruto taught the technique to his apprentice and younger brother Konoha Maru shortly after he learned helix pill. Konoha Maru is also relatively smart, and it didn't take long for him to learn this technique. Moreover, when Penn attacked Konoha, he was a little bit shy but defeated Penn, who even Kakashi could not win. Konohamaru's talent is really high.
On top of the spiral pill, there is a more powerful spiral shuriken. The power of this technique is hundreds of times that of the spiral pill, and if Konoha pill learns it, he will be able to directly possess the power of the shadow level. However, Naruto did not give the ultimate version of Helix Maru to Konoha Maru.
The reason why Naruto did not teach this technique is because Naruto knows that this technique is powerful, but it does great harm to himself. In the battle with Jiaodu, his spiral shurikens all had "ten thousand arrows pierced". But in the same way, Naruto who used this technique also recuperated in the hospital for two or three months due to side effects. Naruto is the body of the Uzumaki family. He needs to recuperate for so long to recover after using the spiral shuriken. If Konohamaru learns and uses it, it is estimated that he will not be able to cultivate for a year.
Because the spiral shuriken is so dangerous, Naruto did not teach this technique to Konohamaru. Naruto did it for Konohamaru. And Konohamaru knew this well, so he didn't ask his brother Naruto to teach him this technique.
Friends, why do you think Naruto did not teach Konohamaru spiral shuriken?
