To pay off the debt, become Hokage!

"By the way." Sarutobi Hiruzen stopped talking about the training ground and changed the subject: "I wonder what level of magic can cause such great destructive power."

He looked up at the boy and said, "Can you tell me about it?"

Uchiha Shigeka nodded immediately. Now that things had come to this, how could he refuse?

Of course I can't refuse, that doesn't fit in with my character who takes the Hokage as his master.

"Hokage-sama, you have seen my Rasengan, right? It is the one I used during the Chunin Exams."

Sarutobi Hiruzen nodded.

Uchiha Shigeka said slowly: "Rasengan is a ninjutsu of form change. On this basis, I incorporated the change of wind attribute chakra nature and further created a new ninjutsu that combines the two."

"I named it Wind Style: Rasenshuriken!"

As Uchiha Shigeka spoke, he looked proud and excited. He talked incessantly about the process of practicing Wind Style: Rasenshuriken, and told Sarutobi Hiruzen in detail and comprehensively the principles of the formation of his ultimate ninjutsu.

As Sarutobi Hiruzen listened, he suddenly felt something was wrong.

Isn't this too detailed? According to Uchiha Shigeka, after practicing for some time, Sarutobi Hiruzen can even make a Wind Style Rasenshuriken with his hands.

Sarutobi Hiruzen looked at the young man in front of him with mixed feelings.

——This child, it turns out that he trusts him so much.

He could even tell him the principles of the ultimate level of ninjutsu... This was completely a heart-to-heart talk, and he truly didn't treat him as an outsider.

So, the unreasonable fear I had before was just an illusion.

"Okay, okay, Chonghua, don't go into so much detail. I'm just curious and want to know what the ninjutsu is."

Sarutobi Hiruzen patted his shoulder and said, "The battle of ninjas is a battle of intelligence. This is your secret technique. Chonghua, forget about it from me, but for others, those who are not recognized or close to you, you must not let them know the principles of the technique."

Uchiha Shigeka's eyes were full of respect and admiration.

He smiled at Sarutobi Hiruzen and said, "Tsunade-sensei is your disciple, and I am Tsunade-sensei's disciple. According to seniority, you are my master. You have all the people who recognize you and are close to you. It will be no problem for you to tell the Hokage!"

"Hahaha." Sarutobi Hiruzen laughed dumbly. He said with a relieved expression: "So, don't call me Hokage-sama from now on. Since you know our generation gap, just call me Master from now on."

Uchiha Shigeka is quick to follow advice.

"Yes, Master!"

Sarutobi Hiruzen was relieved. Taking advantage of his current mood, he thought for a moment and signaled Uchiha Shigeka to follow.

The two walked out of the Hokage's office and came to another more private room.

Uchiha Shigeka looked around curiously. Bookshelves were displayed and books and documents were scattered everywhere: on the shelves, on the floor, on the table, everywhere.

Why did Sarutobi Hiruzen bring him here?

Uchiha Shigeka was feeling anxious, this was truly an unexpected situation.

His mind was full of thoughts and his face showed curiosity and confusion.

Sarutobi Hiruzen asked him to sit here and wait.

When Uchiha Shigeka saw him leave, he carefully opened Kagura's mind eye, but he immediately closed it the next moment.

Wow, it’s not visible to the naked eye, but in fact, there are various sealing barriers everywhere around.

What on earth is this place? Why is it so secretive?

Uchiha Shigeka picked up a book at random.

The Sealed Book

Uchiha Shigeka: ???

Isn't the Sealed Book a big scroll? How can it be a book?

He flipped through it quickly and looked confused.

The cover says "The Book of Seals", but the contents inside are a complete guide to the customs and culture of the Fire Kingdom.

Uchiha Shigeka looked at the files...it was also the "Book of Seals", but it was actually a questionnaire on the food of River Country.

So many unknown book archives with the title of Sealed Book...

Uchiha Shigeka seemed to be thinking about something, and then he understood something, but then it was unbelievable.

This is where the "Book of Seals" under the jurisdiction of successive Hokage is hidden.

Sarutobi Hiruzen brought him here... wasn't it as compensation for telling him the principle of Wind Style Rasenshuriken Technique?

Uchiha Shigeka opened his eyes wide, feeling incredible.

He revealed the principle of the secret technique because he had a lot of cards in his hand and he had no regrets about throwing out a crazy character.

He used Wind Style: Rasenshuriken to invest in his future.

No matter how important magic is, it is not as important as Hokage. As long as he successfully becomes Hokage, he will have plenty of primogems, and he can draw cards as much as he wants and have as many secret techniques as he wants.

But he seemed to have underestimated the damage that doing so would do to Sarutobi Hiruzen.

For the people who were born and raised in the ninja world, the reason why secret techniques are secret techniques is that the word "secret" can explain everything.

Never tell anyone you don’t have a close relationship with or someone you don’t agree with!

Ninja is a profession that brings pain and death, and is trapped in killing and fighting each other.

In order to win and continue to survive, the secret skills that are kept in the bottom of the box are passed down cautiously, and the fewer people who know about it, the better.

As Sarutobi Hiruzen said, the battle of ninjas is a battle of intelligence... although in the eyes of Uchiha Shigeka, a time traveler, this sentence is quite funny.

But this is the mainstream in the ninja world, so Sarutobi Hiruzen was very moved by Uchiha Shigeka's unreserved behavior.

Sarutobi Hiruzen formed seals with his hands, and the scene in front of him changed, and the bookshelf turned into a dark door.

He walked in, and after a while he came out with a huge scroll.

Now it was Uchiha Shigeka's turn to have a complicated look.

"Although I am close to Shigeka and am your master, I am more of a Hokage."

"Zhonghua, you told me the principle of the secret technique. This is out of your kindness, but I can't just ignore it."

Sarutobi Hiruzen patted the scroll beside him and said, "This is the Book of Seals. I think you have heard of it."

"Let's make a deal. I will write Wind Style: Rasenshuriken into the Book of Sealed Swords. In return, you can choose a technique from the Book of Sealed Swords to practice!"

"Ah." Sarutobi Hiruzen suddenly thought of something and said, "Some forbidden techniques are too dangerous, so you shouldn't choose them."

He spread out a small part of the sealing technique, examined it carefully and said, "Just choose one of these techniques. There are risks, but none of them are very high."

After seeing it, Uchiha Shigeka exclaimed, "Wow!"

——Then the remaining majority are dangerous forbidden techniques?

......

Chapter 82: Flying Thunder God Technique

Uchiha Shigeka maintained his character and showed his willingness to refuse.

However, Sarutobi Hiruzen disagreed and insisted that Uchiha Shigeka choose a technique from the Book of Sealed.

There was no way out. Sarutobi Hiruzen’s kindness was hard to refuse, so Uchiha Shigeka could only look at the sealed book with emotion.

Uchiha Shigeka took a look and his eyes were immediately attracted by a ninjutsu.

Sarutobi Hiruzen had been observing him, and seeing this, he followed Uchiha Shigeka's gaze.

"Flying Thunder God Technique, this is a space-time ninjutsu developed by my teacher, the Second Hokage."

Sarutobi Hiruzen fell into recollection and said, "That was not a simple high-speed movement, nor was it an illusion to confuse the opponent."

"The Flying Thunder God Technique is a real space jump!"

"As long as the caster's chakra mark is left, no matter where it is, it can be instantly moved to the place where the mark was left."

Uchiha Shigeka looked up and asked, "No matter where it is?"

"...Well, that's a bit absolute." Sarutobi Hiruzen coughed dryly, "It depends on your chakra. The farther away you are, the more chakra you consume. On the contrary, the closer you are, the less chakra you consume. So naturally, you can teleport anywhere."

"Zhonghua, do you want to learn the Flying Thunder God Technique? This technique is very difficult to learn and the risks are not small."

As the Hokage, Sarutobi Hiruzen naturally read the Book of Sealed thoroughly and did some research on the Flying Thunder God Technique.

The Book of Sealing played an important role in his being called the Ninja Professor.

Of course, he is just a theoretical expert.

Not only are the techniques in the Sealed Book difficult to learn, many of them are not suitable for Sarutobi Hiruzen.

Not to mention that there are some half-finished products and techniques that are still in the realm of speculation.

Those are all left over from the development by the second Hokage, Tobirama Senju.

Sarutobi Hiruzen stroked the sealed book. Most of the dangerous forbidden techniques that were not opened were not usable. There were a lot of deductions and assumptions...

"The Flying Thunder God Technique requires extremely strong reflexes and the ability to perceive time and space."

Sarutobi Hiruzen thought of Uchiha Shigeka's background and outstanding talent, and said: "You have the Sharingan, which has a strong insight ability. Even in the most messy scene, you can instantly lock and confirm the existence of every object."

"Zhonghua, your body movements can keep up with the observation of the three-magatama Sharingan, which fully proves that your reflexes are very strong."

Uchiha Shigeka nodded, that's the truth.

Thanks to the power of the Sharingan, the Uchiha clan's ninjas generally have very good reflexes.

However, reflex nerves can be trained...but this does not apply to people with natural talents like Minato Namikaze.

In short, the reflex nerve requirements of the Flying Thunder God Technique are not high and can be achieved through acquired practice.

The difficulty lies in...

Sarutobi Hiruzen then said: "As for the ability to perceive time and space... this is purely a matter of talent. Some people can easily perceive time and space, while some people cannot perceive the existence of time and space no matter how hard they try."

"The danger of the Flying Thunder God Technique lies here." Sarutobi Hiruzen said with a sullen face, "There are also people who sometimes sense time and space and sometimes not. This situation is the most dangerous."

"If you are not careful, you may be sucked into time and space during your training. Losing your whereabouts is considered good. Some people even have their bodies separated, with the lower half remaining in place while the upper half jumps to the marked location."

"His end..."

Sarutobi Hiruzen shook his head, the meaning was self-evident.

"The difficulty of learning the Flying Thunder God Technique lies in the fact that it requires a lot of talent. Chonghua, you must consider it carefully."

Uchiha Shigeka is undoubtedly a brilliant man, but the ability to perceive time and space is a person's innate talent and cannot be forced.

Sarutobi Hiruzen was not sure whether Uchiha Shigeka had this talent, and he did not want to see a genius encounter an accident while practicing the Flying Thunder God Technique.

"The Flying Thunder God Technique is undoubtedly powerful, but it is also dangerous. Shigeka, the Flying Thunder God Technique is just one of the ninjutsu in the Sealed Book. You can look at other ones."

"Ninjutsu that can enter the Book of Sealing is more or less dangerous." Uchiha Shigeka chuckled: "If there is danger anyway, why not choose the ninjutsu that I like?"

"Master, I have made my choice. I will choose the Flying Thunder God Technique!"

Uchiha Shigeka's eyes flickered. Since he had the chance to learn the space-time ninjutsu that was like teleportation, he naturally wanted to try it.

He couldn't predict whether he would be able to draw a character card that could perform space-time ninjutsu in the future, nor could he predict whether he would be able to get a space-time eye technique like Kamui when he opened a blind box of the Mangekyō Sharingan.

There are too many random things, so it’s better to have a guarantee.

The ability to perceive time and space, I don’t know if he has this talent. I don’t know if Uchiha Itachi, Karin, Ampyou Jūgo’s ancestor, and Kirigakure Passerby have this talent.

He is not fighting alone!

Seeing that Uchiha Shigeka was determined, Sarutobi Hiruzen had no choice but to agree.

Uchiha Shigeka was overjoyed. He was not acting, he was really happy.

Under the supervision of Sarutobi Hiruzen, Uchiha Shigeka opened the Three-magatama Sharingan and recorded the principles of practicing the Flying Thunder God Technique.

Afterwards, he recorded the training method of Wind Style: Rasenshuriken in the Book of Seales.

Wind Style: Rasenshuriken is also dangerous.

Sarutobi Hiruzen had heard about it before in the Hokage's office, but he was still surprised to see the detailed theoretical knowledge now.

Countless fine wind-attribute chakra needles can hurt others and oneself, and can create harm similar to neurotoxins.

This is no less dangerous than the Flying Thunder God Technique.

In order to avoid this danger, Uchiha Shigeka made a note:

It requires advanced medical ninjutsu to instantly heal oneself while being hurt by the Wind Style Rasenshuriken.
