Naruto: Shadow Master of Nara Clan

Chapter 138: The Form of Wind

"Another area for improvement in the Gale Style is actually about 'wind'?"

"What does Shisui mean?"

Listening to Uchiha Shisui's opinion, Koshino immediately became pensive.

However, even if Koshino were asked what Uchiha Shisui's opinion was, he himself seemed at a loss, so how could he answer?

Fortunately, when Uchiha Shisui was giving his opinion on Koshino's Gale Style secret technique, he was simultaneously forming hand seals to prepare a jutsu while discussing his views with Koshino. 

Almost the moment Uchiha Shisui finished speaking, he completed the hand seals and unleashed the jutsu he had prepared.

The name of that jutsu was Wind Release: Blade of Wind!

"Whoosh!"

As the hand seals were completed, Koshino, using his wind perception, naturally sensed the change in chakra nature within Uchiha Shisui.

In that instant, Koshino was indeed a bit surprised, surprised that Uchiha Shisui could complete the nature transformation of wind chakra.

After all, in the original storyline, most members of the Uchiha Clan mastered the nature transformation of fire chakra. 

Even though a few clan members possessed both fire and lightning chakra nature transformations, Uchiha Clan members like Sasuke, 

who were proficient in lightning release jutsu, were still rare, as the Uchiha Clan was best known for their fire release jutsu!

So previously, Koshino had no idea that Uchiha Shisui also mastered the nature transformation of wind chakra, and mastered it so well.

However, seeing Uchiha Shisui mastering the nature transformation of wind chakra, Koshino understood why he wanted to learn about the Gale Style secret technique.

Clearly, Uchiha Shisui encountered issues in using wind chakra and wanted to reference Koshino's new secret technique to enhance his own strength.

Yet, what Koshino should truly be concerned about at this moment was not Uchiha Shisui mastering wind chakra, but the jutsu Uchiha Shisui used.

Wind Release: Blade of Wind is an A-rank wind release jutsu.

And to be honest, the effect of using Wind Release: Blade of Wind is quite similar to the new Gale Style secret technique, Air Blade, developed by Koshino.

The difference is that Wind Release: Blade of Wind requires hand seals to complete, while Koshino's new Gale Style secret technique, Air Blade, is a seal-less jutsu.

The most crucial point is that mastering Wind Release: Blade of Wind only requires completing the first stage of the extreme nature transformation of wind chakra, 

and its effect is certainly not as good as Koshino's new Gale Style secret technique, Air Blade. 

After all, Koshino's Gale Style secret technique, Air Blade, is an ultra-S-rank secret technique mastered only after breaking through the second stage of the extreme nature transformation of wind chakra!

But at this moment, Uchiha Shisui using Wind Release: Blade of Wind still made Koshino's eyes sparkle with a glimmer of light.

Because the moment Uchiha Shisui used Wind Release: Blade of Wind, Koshino understood that the true purpose of Uchiha Shisui using it was to remind him of another area for improvement in the new Gale Style secret technique!

"Yes, the A-rank jutsu Wind Release: Blade of Wind used by Shisui does indeed seem like a weakened version of the Air Blade."

"So what Shisui wants to demonstrate is undoubtedly another area for improvement in the Air Blade. What exactly is it?"

"Wait!"

"Shisui's Blade of Wind, this is..."

Just as Koshino was earnestly contemplating what exactly Uchiha Shisui intended to demonstrate, a strange change occurred in the Wind Release: Blade of Wind technique used by Uchiha Shisui!

One moment, Uchiha Shisui had just finished forming the hand seals and aimed the A-rank Wind Release jutsu, Blade of Wind, at a wooden barrel beside the camp.

"Whoosh!"

With a swing of his right arm, a blade of wind followed the direction of Uchiha Shisui's arm, flying straight towards the wooden barrel next to Koshino's camp. 

If nothing unexpected happened, the wind blade released by Uchiha Shisui would definitely land directly on that barrel, slicing it into two, much like Koshino's Gale Style secret technique, Air Blade.

But in the next moment, just as Koshino's pupils slightly contracted, the form of the wind blade suddenly changed!

In an instant, the wind blade vanished without a trace, and the barrel in front of the camp was suddenly split into several pieces!

Ordinary people might not be able to discern why the barrel broke apart or why Uchiha Shisui's wind blade disappeared in that instant.

But Koshino was different! With his wind perception, Koshino clearly sensed that the reason Uchiha Shisui's wind blade disappeared was due to another transformation in its form! 

Simply put, if the wind blade was considered a form, then at the moment it was about to hit the barrel, Uchiha Shisui's wind blade transformed once more into the form of "wind"!

Wind, by nature, is formless!

Yet under Uchiha Shisui's exquisite control, that gust of wind retained the power of a wind blade! 

Thus, even though the wind blade disappeared, the barrel beside the camp was still split into two! 

Moreover, Uchiha Shisui's demonstration made Koshino clearly understand the message Uchiha Shisui wanted to convey! 

That is, the form transformation of the Gale Style secret technique still has room for a second stage of improvement! 

"That's right! What Shisui wants to express is that the form transformation of the Gale Style secret technique has another level of enhancement, without a doubt!"

"The Gale Style secret technique was originally developed as a breakthrough of the second stage of wind chakra nature transformation, combined with the form transformation of 'wind.' 

However, when I use the Gale Style secret technique, I am still stuck in the first stage of 'wind' form transformation and have not attempted the second stage of 'wind' form transformation!"

"Wind is formless. The tangible 'wind' is indeed very sharp, but the intangible 'wind' is undoubtedly more stealthy and powerful!"

"If I can make the new secret technique Air Blade of the Gale Style become formless, then the power of the Gale Style secret technique can undoubtedly be elevated several levels!"

"But mastering the formless 'wind' is far from as simple as it seems!"

Thinking to himself, Koshino exchanged a glance with Uchiha Shisui, a wry smile appearing on his lips.

At this moment, although Uchiha Shisui could control the form of the Wind Release: Blade of Wind, transforming tangible 'wind' into intangible, 

it's important to remember that Uchiha Shisui was only performing the first stage breakthrough of wind chakra nature transformation. 

Transforming tangible 'wind' into intangible doesn't require much effort. 

In contrast, Koshino's Gale Style secret technique, after the second stage breakthrough of wind chakra nature transformation, would require an unknown amount of effort to research how to transform tangible 'wind' into intangible.

Therefore, even though Koshino understood the new enhancement space for the Gale Style secret technique from Uchiha Shisui's demonstration, 

achieving the second stage breakthrough of form transformation in a short time was still impossible.

However, since there is a new enhancement space ahead, Koshino still has hope of increasing the power of the new Gale Style secret technique.

After exchanging training experiences with Uchiha Shisui, Koshino went to rest after bidding farewell to him.

After all, Koshino's internal injuries had only recently healed, and excessive fatigue would not be beneficial for him!

Yet in his dreams, Koshino undoubtedly kept thinking about Uchiha Shisui's guidance, even practicing the second stage of form transformation of the Gale Style secret technique in his dreams.

This resulted in Koshino appearing somewhat lacking in energy upon waking up in the morning.

But as Koshino forced himself to stay alert, preparing to meet up with Guy, Genma Shiranui, and Ebisu to receive a mission from Shikaku, 

planning to complete today's task before engaging in rigorous training, he noticed something unexpected at the meeting place.

There were four figures instead of the expected three, and Koshino's previously weary eyes suddenly brightened with energy!

"No way, is this a joke?"
