Naruto: The Primal Hyuga Pierces the Shinobi World.

The Flying Thunder God Technique is a space-time ninjutsu developed by the Second Hokage, Tobirama Senju, and is recorded in the Scroll of Seals.

The Book of Seals is a scroll of ninjutsu that records all the forbidden techniques collected since the founding of Konoha Village. It is currently stored in the Hokage Building and kept by the Hokage.

In principle, only the Hokage can read and view the Book of Seals.

The Fourth Hokage, Minato Namikaze, obtained the Flying Thunder God Technique by chance.

During his youth, Minato was already a well-known genius ninja. He possessed great strength at a young age. Not long after graduating from the Ninja Academy and having just obtained his headband and become a ninja, Minato accidentally stumbled upon a heinous incident involving the kidnapping of a future Jinchuriki by the Cloud Ninja.

With his formidable strength and talent, Minato Namikaze rescued Kushina Uzumaki from the Cloud Ninja, making a great contribution.

Not long after that, Minato Namikaze became Jiraiya's disciple, and then gradually made a name for himself in the ninja world with his Flying Thunder God Technique.

Jiraiya was a disciple of the Third Hokage, Hiruzen Sarutobi, and can be considered one of the core figures of the Third Hokage's lineage.

Although Hiashi didn't know much about what happened back then, he understood that Minato Namikaze's ability to obtain the Flying Thunder God Technique was closely related to his identity as "Jiraiya's disciple".

This can actually be seen in the case of Boruto decades later. Kashin Koji, cloned using Jiraiya's bloodline factor, successfully helped Boruto learn the Flying Thunder God Technique. Jiraiya himself probably knew about the Flying Thunder God Technique, but he just couldn't master it or use it.

In the ninja world, each clan and faction has very strict control over ninjutsu. Apart from blood ties and true master-disciple relationships, it is simply impossible for outsiders to learn other people's ninjutsu.

Although the village has a ninja academy and a system of "mentoring students" with Jonin (high-ranking ninja) in charge, the way ninjutsu is disseminated has not fundamentally changed.

Ninja academies only teach basic knowledge about ninjas, and ninjutsu is limited to the Three Body Techniques. The system of Jonin "mentoring students" simply involves Jonin imparting combat experience to their subordinates; they are not required to teach their students any ninjutsu.

More often than not, Jonin teach students based solely on their personal liking, and only one or two lucky individuals are likely to inherit their ninjutsu.

The future Konoha 12 are the best proof of this system.

As the main characters of Team 7, Naruto was trained by Jiraiya, Sakura by Tsunade, and only Sasuke learned the secret technique Chidori from Kakashi.

Of the three students in Class 3—Neji, Rock Lee, and Tenten—only Lee inherited Guy's Eight Gates technique.

As for Hinata, Kiba, and Shino of Team 8, and Shikamaru, Choji, and Ino of Team 10, they didn't learn any ninjutsu from their Jonin leaders, Kurenai and Asuma.

Those who learned secret techniques from Jonin, such as Sasuke and Kakashi, and Lee and Guy, have probably already transcended the so-called teacher-student relationship and advanced to the master-disciple relationship.

Shinichi's desire to ask Minato Namikaze for and learn the Flying Thunder God Technique is, in a sense, somewhat taboo.

The Fourth Hokage could teach them voluntarily, but it would be impolite for outsiders to ask for it, as the relationship between Hyuga and Minato Namikaze wasn't that close yet.

Shinichi, being a transmigrator, naturally lacked some understanding of this aspect, but Hiashi understood it perfectly.

However, he did not scold his son for this. Instead, he lowered his head and pondered seriously. Although Hiashi was strict with Shinichi's training, he actually doted on his exceptionally talented son, though he rarely showed it openly.

Now that his son wants to learn the Flying Thunder God Technique, Hiashi has seriously considered feasible solutions.

He also felt that if his son could learn the Flying Thunder God Technique, combined with the various secret techniques of the Hyuga clan and the Byakugan bloodline limit, Shinichi's potential would definitely far surpass that of the Fourth Hokage!

"While the Fourth Hokage is a kind person, making such a request directly... is a bit too much..."

"We Hyuga can't be so unruly."

At this point, Riji suddenly changed the subject:

"but..."

"Although we can't directly ask the Fourth Hokage for ninjutsu, but..."

"Using the influence of the Hyuga clan, we might be able to request the Fourth Hokage to briefly borrow the Book of Sealing..."

Hiashi Hyuga stroked his chin, as if he had just made up his mind, and his eyes showed determination as he spoke.

"Borrowing the sealed book?!"

Upon hearing this, Shinichi Hyuga was taken aback, feeling quite surprised.

He felt that learning the Flying Thunder God Technique from the kind-hearted Minato Namikaze might be possible.

After all, the Fourth Hokage himself didn't have the idea of ​​keeping a bad broom to himself. Putting aside the fact that the Flying Thunder God Technique is not a "bad broom," Minato actually took the initiative to teach his personal guards Genma Shiranui, Iwashi Tatsumaki, and Raido Namiashi the Flying Thunder God Technique.

However, these three have limited talent, and they can only use the Flying Thunder God Technique together. They cannot use it in battle as easily and freely as Minato.

However, in Hiashi's view, it would be easier to simply borrow the Book of Seals which records the Flying Thunder God Technique than to "rudely" ask the Fourth Hokage to teach the Hyuga clan the Flying Thunder God Technique.

Although the Scroll of Seals is a forbidden scroll that only the Hokage can read, it is the "common treasure" of the Konoha ninjas. It is not entirely impossible for the Hyuga clan, a major clan in Konoha, to borrow it.

Moreover, since the Hyuga clan is already preparing to make a request to the Hokage, simply asking for the Flying Thunder God Technique would be petty. It would be better to risk the Hyuga clan's reputation and get it done directly, while also using this opportunity of "asking for a favor" to strengthen the connection with the Hokage.

"Shinichi, I've noted down your desire to learn the Flying Thunder God Technique. I'll find a way, so you don't need to worry about it."

"Don't think about the Flying Thunder God Technique for now. Focus on cultivating the family's secret techniques. I have high expectations for you, so don't let me down."

"Go on, you haven't finished your training for today. Go back to your practice."

Hiashi Hyuga waved to Shinichi Hyuga to leave. Shinichi nodded and left as well, not really having high hopes for learning the Flying Thunder God Technique.

After all, it's a secret technique; obtaining it won't be so easy.

However, what Shinichi didn't know was that while he was leaving the tea room to continue his training at the dojo, Hiashi changed his clothes, summoned his younger brother Hyuga Hizashi, and then hurriedly gathered several elite ninjas from the branch family before rushing towards the Hokage Building.

...

After leaving the Hyuga clan, Minato and his wife did not return to the Hokage Building with the Third Hokage. Kushina was about to give birth, and Minato's biggest task at the moment was to take care of Kushina. As for the affairs of the Hokage, Hiruzen Sarutobi kindly took over them all.

In response, Minato and his wife should thank Hiruzen for taking care of them.

In the Hokage's office, Hiruzen Sarutobi sat behind his desk, looking at the piles of documents on it. He slowly took out his pipe from his pocket, lit a match, lit the tobacco, and then took a few satisfying puffs.

Wisps of smoke rose into the air. Hiruzen raised his head slightly, glanced around the Hokage's office, whose layout had not changed much, nodded to himself, and a satisfied smile appeared on his face.

Towards the end of World War III, small-scale conflicts frequently occurred along the border. As the Hokage, Hiruzen had a lot to deal with every day. After a short rest, he buried himself in his paperwork, unaware of the passage of time.

Although Hiruzen Sarutobi had a strong desire for power, he was also very efficient in handling affairs. Perhaps his decentralization of power over Minato, the Fourth Hokage, stemmed simply from a deep-seated distrust of the young Hokage...

After an unknown amount of time, there was a sudden knock on the door of the Hokage's office.

Hiruzen Sarutobi raised his head, rubbed his slightly tired cheeks, and said in a deep voice, "Go!"

Without needing to be announced by anyone, Hyuga Hiashi led eight neatly dressed Hyuga clan ninjas into the office after the door opened.

Upon seeing the Third Hokage behind the desk, Hiashi was momentarily taken aback, but quickly regained his composure. After a slight bow, he smiled and stepped aside to introduce him:

"Third Hokage, these are the Hyuga clan ninjas I selected to assist the Anbu in their protection mission."

"This is my younger brother, Hyuga Hizashi. This is Hyuga Daiki, Hyuga..."

After introducing the young ninjas behind him, Hiashi turned around and looked at Hiruzen Sarutobi.

After carefully listening to Hiashi Hyuga's introduction, Hiruzen Sarutobi nodded with a smile and praised him:

"As expected of you, you really are efficient! You selected the ninjas for the mission so quickly."

"And they even came in person."

"On behalf of Minato and Kushina, I thank the Hyuga family for their help."

Hiruzen Sarutobi nodded politely, walked up to Hiashi, and gently patted Hiashi's arm to show affection.

"Hehe, that's only right."

"Moreover, besides bringing these people to see you, I actually have another request to make."

"Third Hokage, please allow us to borrow the Book of Seals, considering the many efforts and contributions our Hyuga clan has made for Konoha over the years."

The Japanese team had absolutely no negotiation skills and went straight to the point.

His words left Hiruzen Sarutobi and the Hyuga clan members behind him stunned.
