Researching Medical Ninjutsu

Yei's earlier request to ask Gai about the Steel Fist Style had not been a spur-of-the-moment decision; he truly had a need for it.

He had simply happened to run into Gai, and since he also wanted to learn a little about the Eight Gates Formation, he brought it up while he had the chance.

Besides, construction on his laboratory was far from adequately prepared at the moment... Well, it was more accurate to say that almost nothing had been prepared, so there was no need to rush...

That was how this sparring session came about!

As for what he had gained...

Aside from gaining a better understanding of Gai's attack patterns, he had gotten almost nothing substantial regarding the Eight Gates Formation...

As expected, trying to uncover the secrets of the Eight Gates Formation through a single battle is still a little unrealistic. I'll take it slowly... Yei mused inwardly.

"I see. Judging by that final strike of yours, you must have gained something, right?" Gai nodded. During their battle, he had noticed that while Yei's Eight Trigrams Sixty-Four Palms differed somewhat from those of the other Hyuga Clan members and were more powerful, its attacking method still remained within the scope of the Gentle Fist. Moreover, the transitions were somewhat unpracticed, leaving a few openings.

Otherwise, blocking Yei's Eight Trigrams Palm would not have been nearly so easy for him...

Only those final twin palms had truly surprised him. That strike seemed to perfectly combine two styles, possessing both the precision of the Gentle Fist and the fierce power of the Steel Fist Style!

Even Gai could not help but marvel at what a genius Yei truly was!

Yei smiled. "You could say I gained a little, but it still needs further refinement. I may need to spar with you more in the future so we can improve together!"

Gai gave him a thumbs-up and flashed his trademark smile. "Of course! You're an 'eternal rival' I acknowledge, just like Kakashi. You can come spar with me anytime! But next time, I won't lose to you again!"

Yei chuckled and teased, "Heh, you're still far from defeating me! Don't forget, I didn't use my Lightning Release ninjutsu even once this time!"

Gai's expression fell at those words, but he quickly rallied. Brimming with energy, he declared, "Even so, my Steel Fist Style won't lose to anyone!"

Yei shrugged. "As long as you have that confidence."

Glancing at the devastated training ground and the darkening sky, Yei said to Gai, "Let's go. It's time to head back."

Gai nodded. "Alright."

The two vanished in a flash and left the area, returning to Konoha Village.

After parting ways with Gai, Yei returned to Hyuga Yue's home. Once they had finished dinner, Yei and Hyuga Yue sat together on a set of steps at the training ground, gazing at the full moon in the sky as they chatted and laughed.

That night, after obtaining the basic applications of Medical Ninjutsu from Hyuga Yue, Yei returned to his own home.

These were merely the most basic applications of Medical Ninjutsu. There was no need to keep them secret, nor did Hyuga Yue need to worry about being held accountable.

As he had said before, Yei was somewhat interested in Medical Ninjutsu, as it would be helpful for some of his future plans.

It was not merely for his future biological research. He also needed to find a suitable explanation for his Super Regeneration, and Medical Ninjutsu happened to be a breakthrough point!

Spreading open the scroll, Yei looked it over and began experimenting.

As he experimented, a faint green Chakra appeared in his hand. However, it lasted only a brief moment before dissipating.

"This kind of fine control is much harder than simply expelling Chakra from the acupoints. Still, as long as I practice it a few more times, it shouldn't be too difficult for me..." Yei activated his Byakugan, and faint green Chakra once again swirled around his hands.

Through the Byakugan's observation, Yei discovered that although he had condensed faint green Chakra, it was still somewhat different from the Chakra Hyuga Yue had used to heal him...

Hyuga Yue's faint green Chakra was gentle and delicate, almost completely devoid of any destructive nature.

Yei's, on the other hand, had formed into a faint green mass of Chakra under his control, but if he used it to treat someone, he would very likely heal them to death...

"Looks like it isn't as simple as I imagined..." This time, under Yei's control, the faint green Chakra mass lasted longer and began to change, but it still could not achieve the delicate, gentle quality of Hyuga Yue's Chakra...

Yei was not discouraged. No ninjutsu could be mastered overnight.

Even though he possessed Electromagnetic Control and faced virtually no bottlenecks in cultivating Lightning Release ninjutsu, he still needed time to familiarize himself with and master them...

At first, Yei had believed that Medical Ninjutsu was like other ninjutsu, perhaps requiring some sort of "trait" to perform. He thought that those unable to learn Medical Ninjutsu lacked the "Yang" Release Chakra nature.

Just as ninjutsu of different natures required the corresponding Chakra nature to be performed, Medical Ninjutsu was connected to restoration and vitality, so it likely required Yang-natured Chakra!

However, after reading the medical scroll, Yei discovered that Medical Ninjutsu had no such restriction. As long as one could precisely control Chakra, any ninja who possessed Chakra could learn and perform Medical Ninjutsu. There were no necessary prerequisites!

If there was a requirement, there was only one: precise control over Chakra. That was where the difficulty lay!

If one could not achieve precise control, they might end up like Tenten in the original story and directly heal a fish to death...

Therefore, the Hyuga Clan truly possessed an innate advantage in this area. With the Byakugan, they could naturally "see" the flow of Chakra within their bodies, and because they trained in the Gentle Fist from childhood, they could achieve such precise Chakra control!

It could be said that every member of the Hyuga Clan possessed the qualifications to become a Medical Ninja. It was only because of a certain pride that Hyuga Clan members rarely became Medical Ninja!

Of course, precise control alone was not enough. The practitioner also needed knowledge of the human body, meridians, acupoints, and other medical matters. Otherwise, they could still heal someone to death. All of that required time to learn and master!

And this was only the simplest form of Medical Ninjutsu. More advanced Medical Ninjutsu would presumably be even more difficult and require even more knowledge.

In terms of difficulty, it might even surpass A-rank or S-rank ninjutsu...

To obtain more advanced Medical Ninjutsu, one either had to join the medical corps and exchange contributions for it, or find a good teacher...

However, Yei was not thinking that far ahead for now. The most basic applications alone were enough to keep him occupied with research for quite some time.

Looking at the faint green Chakra mass around his hands, Yei sighed softly. "No wonder Medical Ninja are in such short supply. The difficulty really isn't low. Precise Chakra control alone weeds out a huge number of people. Not everyone can see their own Chakra flow like the Hyuga Clan..."

Medical Ninjutsu was more difficult than he had imagined.

In a sense, precise Chakra control could also be considered a kind of talent!

Like Chakra natures, it was a talent that could only be encountered by chance...

After all, not everyone could be like the Hyuga Clan, possessing the Byakugan bloodline limit and learning the Gentle Fist, a form of Taijutsu that required precise Chakra control, from childhood!

That was why Yei felt that the ability to precisely control Chakra might truly be a rare talent in some respects...
