Webnovel Author: Revelature - Fanfic Collection

Probably the only one that is impressed by Kizaru's dodging style would be Naruto and Sasuke. And the Third and Kakashi will attribute it to his speed anyway. And Kizaru will reveal part of his strength in Konoha Crush Plan. So it will not affect much if he tells Naruto and Sasuke the blindfold training.

Well, it's already unusual in itself that Kizaru can dodge attacks so easily. Additionally, apart from Observation Haki, he hasn't revealed his Armament Haki yet. Naturally, characters will find it unusual how he can predict or sense attacks. Kizaru, like Saitama, will simply explain to Naruto how he achieves such a state by using the blindfold method. Powerful characters in Naruto will underestimate such a practice and consider it unworthy of their attention and time. They will view the technique as stupid. Besides, they don't truly understand the potential of Observation Haki, so they will attribute Kizaru's ability to dodge Naruto and Sasuke's attacks to his speed alone.

Kizaru is currently contemplating whether the main characters, Naruto and Sasuke, possess the ability to acquire Haki. Specifically, he is interested in their potential to learn Observation Haki, a technique demonstrated during Rayleigh's training of Luffy. Rayleigh trained Luffy while blindfolded, teaching him to sense his surroundings without relying on his vision, which eventually led to the development of Observation Haki. The question at hand is whether Naruto and Sasuke will be able to learn this skill. However, there is no need for concern, as Kizaru intends to provide them with a vague explanation of the basic principles of Observation Haki, and he will not teach them Armament Haki. The decision of whether Naruto and Sasuke will pursue this suggestion from Kizaru ultimately depends on their determination and patience. (Actually it will depend on me. However, in my writing, I strive to maintain the characters' personalities from the original series and their current timeline personality, which will influence how they respond to this opportunity.)

As he still have a lot to know of the world of Naruto.

If you read carefully, the mc didn't finish Naruto. So he felt cautious since he didn't feel safe and only watched early episodes of Naruto series.
