It's been 24 years, why am I reincarnated in Konoha without a system?

Chapter 51 The Book of Sealing, I Need the Art of Spirit Transformation

"You mean, the Third Hokage is going to inscribe the Lightning Release Armor into the Scroll of Seals??" Ishikawa exclaimed in surprise upon hearing Kakashi's inquiry.

Honestly, Ishikawa was already grateful that Kakashi allowed him to train in Lightning Release Armor; how could he possibly hope for anything else?

So, do we need to ask for his opinion on this?

Without Kakashi and Tsunade, Ishikawa would have been defeated before he could even touch the Raikage, so what complaints could he possibly have!

"You can decide on this teacher yourself, no need to ask me." Ishikawa quickly agreed, then scratched his head and feigned curiosity, "By the way, what exactly is that Book of Sealing?"

"The Scroll of Sealing Techniques! It's a comprehensive collection of forbidden ninjutsu, dating back to the First Hokage." Kakashi paused upon hearing this, then looked intently at Ishikawa. "So, Ishikawa, would you like to learn the ninjutsu from the Scroll of Sealing Techniques?"

"Ninjutsu from the Scroll of Seals?" Ishikawa's face fell immediately upon hearing this. "Teacher, this joke is not funny at all! How could a genin like me be able to learn ninjutsu that the Hokage has listed as forbidden techniques?"

What a joke! He can't even master his own few ninjutsu techniques, how could he be qualified to learn those forbidden techniques? Besides, the Thousand Hands Strength, Lightning Release Armor, and Rasengan—aren't they all forbidden-level ninjutsu?

Why go through all that trouble, only to find that half-full buckets of water make no sound and then rattle away...?

"That's true. It's indeed a bit difficult for you to master forbidden techniques with your chakra." Kakashi smiled with satisfaction, then scratched his head and walked towards the Hokage Building. "Oh dear, this is a bit tricky!"

"I've already guaranteed you the opportunity to learn a ninjutsu from the Book of Seals as a condition for inscribing the Lightning Release Armor. Looks like I'll have to learn it myself, what a hassle..."

"Wait!!" Upon hearing this, Ishikawa immediately shouted to stop Kakashi, his eyes burning and his breathing rapid. "I'm willing to share the burden with you, teacher. Leave this troublesome matter to me."

"Teacher, we'll meet at the Hokage Building later. I'll go back and get the scroll now." After saying this quickly, Ishikawa unleashed a burst of chakra and sped home.

Just kidding! Why wouldn't you accept a forbidden technique that's offered to you?

Ishikawa said that before because he was in a lowly position and didn't have much influence, and thought Kakashi was joking.

But now that Kakashi has vouched for the Third Hokage, it would be truly foolish for him not to appreciate it!

As for not having time to cultivate? Who cares, let's get the benefits first! Whether to cultivate or not is one thing, having something to do with it is another.

"That guy..." Kakashi smiled, shook his head, and turned to walk towards the Hokage Building, watching Ishikawa's rapidly departing figure.

The Scroll of Sealing Techniques wasn't particularly alluring to him, given his Sharingan. His greatest weaknesses were chakra and physical strength; ninjutsu was secondary!

Perhaps he should also train in that Lightning Release Armor...

Ten minutes later, in the Hokage's office.

"This is the Book of Sealing Techniques. You can only choose one ninjutsu from it to practice." After inspecting the Lightning Release Armor, the Third Hokage took out the Book of Sealing Techniques that had been prepared beforehand and said to Ishikawa.

"Yes, Hokage-sama." Ishikawa immediately agreed and opened the Book of Seals under the watchful eyes of the Third Hokage and Kakashi.

The scroll had barely been opened when the first forbidden technique was revealed to be the protagonist's cheat-like ability: Multiple Shadow Clone Technique!

Ishikawa merely glanced at the forbidden technique before quickly flipping through the page, showing absolutely no desire to learn it.

Admittedly, the Multiple Shadow Clone Technique is an unparalleled cheat code for both combat and training. However, its drawbacks are also obvious: chakra and memory feedback.

Ishikawa didn't have that much chakra to waste, and he didn't know if he could withstand the impact of the shadow clone's memories, so he naturally skipped it. As Ishikawa turned the scroll, the second forbidden technique of Konoha came into view.

"This is the Illusion Technique: Dark Travel Technique, a forbidden technique that the Second Hokage included in the Book of Seals. Its effect is to deprive the enemy of their sight..." Seeing Ishikawa's gaze pause, the Third Hokage began to explain.

"A visual illusion?" Kakashi whispered from behind, surprised that such an illusion existed.

Judging from the effect, it should be a high-level illusion technique specifically designed to counter eye techniques.

"Huh? This is..." Ishikawa patiently listened to the Third Hokage's rambling, then looked further ahead and his pupils shrank.

The Third Hokage beside him glanced at it, his gaze filled with a sigh. "An S-rank forbidden technique, Spirit Transformation Technique..."

"This is a Soul Assassination Technique that shone brightly during the Second Shinobi World War. Its effect is to separate the soul from the body and transform it into a spirit body. This spirit body can then possess the enemy to fight or directly attack the enemy's spirit."

"In addition, the caster who transforms into a spirit can sense the location of the soul of a familiar partner no matter how far away they are, and can quickly reach the other person's body after transforming into a spirit, no matter how far away they are."

"Whether it's transmitting intelligence, confirming someone's life or death, or even providing them with chakra, it can all be done."

As the three generations continued to explain, Ishikawa's eyes grew brighter and brighter!

"This, I want to learn this!" Without hesitation, Ishikawa pointed to the Spirit Transformation Technique and exclaimed excitedly.

He never expected that Kato Dan's Book of Soul Sealing Techniques also contained records of this. With this, he could possess Nohara Rin and go to the Third World War timeline, significantly improving his safety.

It would be an absolute injustice not to choose this!

"This? This technique requires a great deal of soul strength. The stronger the soul, the easier it is to cultivate. Conversely, if the soul is weak, it is more difficult to cultivate, or even impossible. Because it involves the soul, it is classified as a high-difficulty forbidden technique of S-rank difficulty." The Third Hokage kindly advised, implying that he hoped Ishikawa would choose another ninjutsu to cultivate.

While soul strength cannot be measured, spiritual energy serves as a reference for it, and chakra, which is composed of spiritual and physical energy, is the most direct proof of soul strength.

Therefore, this is an S-rank forbidden soul technique that only Jonin are qualified to practice.

Having promised Kakashi, the Third Hokage decided to mentor Ishikawa. He couldn't let such a promising and innocent junior waste his time and hinder his growth.

"No, I want this one! Third Hokage..." Meeting the Third Hokage's gaze, Ishikawa once again declared firmly.

It's just soul strength! Although it sounds a bit boastful, as a transmigrator, Ishikawa doesn't think his soul strength is that weak.

If even the indigenous people can successfully cultivate, why can't he?

"This one, Third Hokage." Seeing that the Third Hokage was still hesitating, Kakashi's eyes flashed and he slowly spoke.

Now that Ishikawa has the Thousand Hands Strength and Lightning Release Armor to train, perhaps this technique would be better! He had previously worried that Ishikawa might be distracted if he chose a particularly powerful forbidden technique, but he didn't want Ishikawa to give up this rare opportunity.

I'll choose the Spirit Transformation Technique now, so that Ishikawa will give up once he fails to train in it. Then I'll focus all my energy on learning Super Strength and Lightning Release.

As for the Spirit Transformation Technique, it's not too late for him to learn it after he becomes a Jonin.

Seeing that Kakashi and Ishikawa shared the same attitude, the Third Hokage sighed and nodded helplessly...

Then let's use the Spirit Transformation Technique to test whether Ishikawa is a genius or not!
