Reborn Naruto, I rolled my eyes to the sky

Sarutobi Hiruzen introduced us to the basics of the Sealing Technique: "Sealing Technique is a high-level ninjutsu that you probably haven't come into contact with in the Ninja School."

"Even in the ninja world, there are not many ninjas who can master the sealing technique. The most famous of them is the Uzumaki clan of the Whirlpool Country."

"What Mito-sama and Kushina are using now is one of the advanced sealing techniques - the Diamond Seal." Sarutobi Hiruzen explained: "This technique is a secret ninjutsu of the Uzumaki clan. It is very complicated and has certain requirements for bloodline. It is difficult for you to learn it."

"What I'm going to teach you today is another sealing technique that has a certain restraining effect on the tailed beasts - the Four Symbols Seal, which is the technique I performed today when Kushina's tailed beast went berserk."

"The Four Symbols Seal is also a high-level sealing technique that is passed down secretly by the Uzumaki clan. However, compared to the Diamond Seal that focuses more on bloodline power, the Four Symbols Seal is more important for the practitioner to understand the sealing technique itself."

"You should have all learned that the Four Symbols represent the four heavenly spirits of Azure Dragon, White Tiger, Vermillion Bird and Black Tortoise. They also represent the four images of the Sun, Lesser Yang, Taiyin and Lesser Yin. So if you want to practice the Four Symbols Seal, you need to have a deep understanding and realization of this knowledge."

"Of course this is not knowledge and ninjutsu that can be mastered overnight. Today I will teach you the order of hand seals and the circulation of chakra. The rest you need to practice diligently after you go back." Sarutobi Hiruzen said as he took out two scrolls and handed them to Minato and me.

"Yes, Hokage, we will practice diligently." Minato and I agreed. Sarutobi Hiruzen didn't give any other instructions. We took the scroll of the Four Symbols Seal and left the Hokage Building.

"Let's go visit Kushina first. If there's nothing wrong with her body, we'll go to Konoha Forest to study this scroll. I'm still somewhat interested in sealing techniques." I said to Minato.

"Okay," Minato replied, and the two of us headed in the direction of the medical unit.

After arriving at Kushina's room, I felt several inquiring gazes secretly sweeping over the two of us. They should be the Anbu and Root ninjas arranged by Sarutobi Hiruzen.

After all, whether as the descendant of the Uzumaki clan or Konoha's current strategic weapon, the Nine-Tails Jinchuriki, Kushina's importance is self-evident. What's more, the village has just experienced the Cloud Ninja kidnapping incident, so it is impossible not to pay attention to it.

We entered the room and Ling and Nono, who had rushed over after hearing the news, were both there. Kushina had also woken up and was leaning on the bed, talking to the two of them. She looked fine except that she was a little weak.

"Hey, Minato, is your arm okay?" Kushina saw Minato and I come in, and before we could ask about her condition, she asked with concern.

Before Kushina fell into a coma and the Nine-Tails went berserk, she was seeing the fight between Minato and the Cloud Ninja. Minato's watch was badly damaged and some of his blood flowed onto her body.

Ling also looked at me with concern. After all, Minato and I were fighting against a Cloud Ninja team, which included a Jonin and three Chunins, so it was inevitable that some of them would get hurt.

I smiled at Ling and shook my head, indicating that I was fine. Minato also waved his arm at Kushina: "It's nothing serious. It has healed after being treated by the medical ninja."

In the room, we confirmed that each other was in good health and felt relieved. We also talked for a while about the front line of the Rain Country and the developments of the Thunder Country.

During this time, Kushina saw the scrolls in Minato and I's hands, and we repeated Sarutobi Hiruzen's request to us.

"The Four Symbols Seal? This is a very advanced sealing technique. Even among the Uzumaki clan, only a few people have mastered this technique. Learning it requires quite profound theoretical knowledge."

"I spent all my time practicing the Diamond Seal before. This technique doesn't require much in terms of theory, but mainly the blood of the Uzumaki clan and the huge amount of chakra."

On the way here, I also roughly looked through the scroll of the Four Symbols Seal. What Sarutobi Hiruzen and Kushina said was right, this technique involves quite advanced theoretical knowledge.

In fact, there is no shortage of basic theoretical knowledge and methodologies for understanding the world in the ninja world. It is just that due to the length and lack of history, there is no systematic summary.

Just like when I was developing the method of the Twelve Earthly Branches Fundamental Seals, my ideas and inspirations were naturally the most important foundation, but the theoretical and knowledge research about the Twelve Earthly Branches has actually always existed in the ninja world, which is why I was able to successfully develop this method.

As for the Four Symbols Seals, Eight Gates and various Five Elements Ninjutsu, they actually all correspond to various advanced theoretical knowledge. It’s just that the practicing ninjas do not understand them in depth, which makes the practice of the ninja world look very primitive and rough. In fact, each ninjutsu is worth in-depth study.

There is one advantage for me in practicing the Four Symbols Seal at this time. That is, in the process of developing the Twelve Earthly Branches Fundamental Seal method, I have learned and sorted out a lot of theoretical knowledge in the ninja world, including the meaning and imagery of the Four Symbols.
