Naruto :Uchiha's Reincarnation

Although Haruto had learned the basics of hemostasis, he was still considered a beginner and could only perform simple wound treatments after a battle.

In combat, it would take him several minutes to stop the bleeding from a shallow wound, which was not fast enough to be effective.

"Not bad!" Tsunade said after instructing Nami Aburame and Ryo Inuzuka, nodding in satisfaction.

"But just this isn't enough to prove you have the potential to become a qualified medical ninja. At the very least, you need to complete the next step—reviving a dead fish—to show that you have sufficient chakra control to learn advanced medical ninjutsu. But we'll get to that later!"

After Tsunade finished speaking, she glanced at Kato Dan, who was busy grilling fish over the fire.

"The most important thing for now is to deal with these pheasants and rabbits first and fill our stomachs."

Before long, the game had been gutted by Haruto and the others, with the blood drained. They then smeared the meat with herbal juice and honey that Tsunade had brought. Finally, the pheasants and rabbits were skewered with branches, trimmed by kunai, and placed on a makeshift rack built by Kato Dan.

Normally, this kind of meal would take a long time to cook over an open flame, but as an experienced ninja who had mastered the fire chakra nature, Kato Dan easily controlled the temperature with his fire-style ninjutsu. He finished cooking everything in just over 20 minutes.

Judging by Kato Dan's smooth and practiced movements, it seemed like he'd done this many times before, likely while on missions with Tsunade.

After all, with their strength, most missions could be completed easily, leaving the remaining time for either training or relaxing.

The roasted pheasant was golden and crispy on the outside. When torn open, the tender, juicy meat inside was soft and elastic. It was crispy on the outside, tender on the inside, and left their mouths full of flavorful oil.

The three junior ninjas in Kato's team sat around the fire, chatting casually about their views on their future while enjoying the delicious barbecue.

Meanwhile, Tsunade sat by the river with her hands on her knees, talking quietly with Kato Dan.

"If you're done eating, come over here."

Kato Dan suddenly called to his three disciples after they finished eating.

Looking at the three who had undergone the baptism of battle and had noticeably matured, Kato Dan's handsome face softened into a faint smile.

"I've been your instructor for a while now, and apart from taking you out for barbecue a few times, I haven't given you any real gifts. So, I thought I'd take this opportunity to teach you a unique secret technique that I created myself."

Kato Dan stretched and took out a small scroll from the ninja pouch on his waist.

Haruto's heart skipped a beat.

Could this be what he thought it was?

But after giving it some thought, it seemed unlikely. Even if Kato Dan wanted to teach them something extraordinary, the three Genin likely didn't have the foundational skills to learn forbidden techniques at that level. It must be something else.

As expected, Kato Dan spread the scroll in front of them and began to explain:

"There's a forbidden jutsu in the village called the Spiritualization Technique. It's been passed down in the Kato clan for generations, but it's incredibly dangerous to practice, so I won't be teaching you that. What I want to show you is a secret technique that activates mental power and develops spiritual energy. It's based on the Kato clan's centuries of experience with practicing the Spiritualization Technique. This one is called the Spiritual Activation Technique."

"This technique helps develop a person's spiritual energy to its fullest potential. How much you can improve depends on your innate mental strength. I was able to learn the Spiritualization Technique because I was born with an unusually large amount of spiritual energy, which was fully developed through the Spiritual Activation Technique."

Kato Dan paused and looked at his three students with his deep blue eyes.

"When your mental energy reaches a certain level, it will greatly enhance your ability to control chakra."

At this point, Tsunade raised her hand and interrupted.

"It was only after learning this secret technique that I was able to use medical ninjutsu that others couldn't, thanks to the precise chakra control it enabled."

Kato Dan nodded and continued:

"Improving your chakra control can help with any ninjutsu, especially medical ninjutsu, which demands the highest degree of chakra precision. For sensory ninjas like Ryo and Nami, further development of your mental energy will also significantly enhance the power of your sensory abilities."

Afterward, Kato Dan turned his gaze toward Haruto.

"As for you, Haruto..."

"Sensei, could you stop with the suspense already?" Haruto interrupted, unable to contain his curiosity. "Will this technique affect the Sharingan in any way?"

Haruto knew that advancing the Sharingan to higher levels could have a significant impact on one's mind and personality. What if Kato Dan's Spiritual Activation Technique conflicted with the Sharingan? Missing out on learning such a powerful technique would be a major setback.

"I'm not sure," Kato Dan admitted with a shake of his head.

"But based on the principles behind it, there shouldn't be any conflict with bloodline abilities. In fact, in my experience, the Spiritual Activation Technique is compatible with nearly all forms of ninjutsu. What I want to tell you, Haruto, is that both you and I were born with an extraordinary amount of mental power that most people can't achieve."

"In other words, you have a high likelihood of mastering the Spiritual Activation Technique to its fullest extent, just like I did."

At that moment, a Senbon floated in front of Kato Dan.

"That is the power of using mental energy to perform Yin Release without any medium—directly influencing the physical world."

As he finished speaking, the Senbon gently floated back down to the ground.

This was similar to the shadow-style techniques of the Nara clan, but while the Nara clan's jutsu relied on the Yin Release and used shadows as a medium, Kato Dan's technique used pure mental energy.

"If you can do this, it means you have the qualifications to learn the Spiritualization Technique."

Kato Dan picked up the Senbon and placed it back in his pouch.

"You two as well," he said, turning to Ryo and Nami.

Both of them were exceptionally talented, but the difficulty and danger of mastering the Spiritualization Technique were incredibly high.

In the past, many extraordinarily gifted people had attempted to learn it, but almost all had failed and perished in the process.

Without enough mental strength to influence reality, it would be impossible to control one's soul and leave the body at will. This was the standard Kato Dan had set for safely learning the Spiritualization Technique.

Like Kato Dan himself, Haruto was born with strong mental power that most people couldn't hope to achieve. With further development through the Spiritual Activation Technique, he had a good chance of reaching that level.
