Naruto: Sasuke and Naruto Hot Heaven

Naruto gradually realized that the Uzumaki clan was not only the largest family in the Whirlpool Country, but they were also the founders of the Whirlpool Country and the first inhabitants of this island.

It is said that the Uzumaki clan are the protectors of the village, responsible for mediating disputes between families, searching for children with chakra gifts, and protecting the safety of civilians in times of war.

In reality, the Uzumaki clan does not have a large population, and the reason they are able to take on the responsibility of guardians is because they have the support of other families.

In the treasury, a large part of the space is used to store items donated by other families. These items were contributed by ninjas who have no family inheritance, or ninjas from some small families.

The walls of the treasury are lined with niches filled with scrolls, books, and charts. Each niche is engraved with the name of the donor, including some famous figures.

And in the center of the room was a circular shelf, on which were placed various precious scrolls and rare artifacts, which were the true treasures of the Uzumaki clan.

Naruto ignored those things. He walked straight to the shelves where the books on sealing techniques were placed and began to read them.

He absorbed knowledge eagerly, and soon the floor of the treasure house was filled with open books and unfolded scrolls, which were densely covered with various sealing techniques.

Whenever Naruto encountered unfamiliar symbols or terms that he did not understand, he would stop to think, and every time at this time, some scattered fragments of memory would emerge in his mind, which were the crystallization of wisdom left by the ancestors of the Whirlpool Country.

With the help of these memory fragments, he gradually understood the meaning of those lines and symbols, and their role in sealing techniques. He began to understand how to use these symbols to guide and transform energy, and how to create different types of sealing techniques with different effects.

Among this pile of messy scrolls, one scroll stood out particularly. It was a copy of the Nine-Tails Sealing Technique.

Naruto sat cross-legged in front of the scroll and began to try to modify the sealing technique.

The core structure of the sealing technique cannot be changed. Even if Naruto knew how to remove the seal, he cannot do so because doing so would be tantamount to suicide.

The internal structure of the sealing technique is responsible for creating an independent space to imprison the tailed beasts; the middle part is responsible for isolating the chakra of the jinchūriki and the tailed beasts; and the external structure is responsible for suppressing the chakra of the tailed beasts to prevent them from escaping.

The sealing technique in Naruto's body is slightly different from the original sealing technique. The middle part of his sealing technique, that is, the part connecting the inside and the outside, is too loose, allowing the Nine-Tails' chakra to easily penetrate.

Not only that, his sealing technique was also missing some key runes, and the function of these runes was to prevent the Nine-Tails' chakra from leaking out.

What Naruto needs to do now is to repair the flaws in the sealing technique.

He planned to add an opposite sealing technique to the outer structure of the sealing technique, so that he could seal both his and the Nine-Tails' chakra in a shared space, instead of suppressing each other as they were doing now.

Then, he only needs to modify the rules of the sealing technique to allow chakra to flow in both directions.

Of course, this is easier said than done.

In order to achieve this goal, Naruto needs to create a set of sealing jutsu extensions called "Violation Lines".

The lines themselves are not complex, but require a lot of rules and supplementation to work.

After careful consideration, Naruto decided to divide this plan into four stages.

First, he needed to add a balance point to the core structure of the sealing technique, and then create sixteen "bridges" to connect the internal space of the sealing technique with the external space. These "bridges" looked like short lines, but they could allow Naruto's chakra to connect directly to the sealed space of the Nine-Tails.

Secondly, he needed to set up some "sampling points" along the main channels where his chakra flowed.

The function of these "sampling points" is to guide and fix the "violation lines" so that they can move freely along Naruto's body and extract chakra. These "sampling points" will be composed of a series of special runes, which will support the existence of the "violation lines".

This is also the most complicated and important part of the entire plan, because the location of the "sampling point" will determine how the "violation line" operates.

The third step is to draw the "violation line", which is also the step that consumes the most chakra.

Naruto needs to start from the farthest "sampling points", which are the neck, wrists and ankles, and then slowly extend inward until all the "sampling points" are connected together.

The last step is to reinforce the sealing technique, using a circular sealing technique to fix the "violating line" and "sampling point" to activate the operation of the sealing technique.

Naruto was immersed in the world of sealing techniques and completely forgot about time and hunger.

When he finally finished all the design drawings, it was already late at night, his legs were numb, and his stomach started to growl.

He took out a box of curry and rice given to him by Teacher Iruka and ate it while checking his design drawings.

He still needed some materials, such as special ink for sealing and transfer runes, but the hardest part was already done.

Iruka-sensei's curry helped Naruto regain a lot of strength. After a hearty meal, he felt his mind was much clearer. The long hours of reading and thinking had given him a headache, but now it was much better.

He couldn't help but start missing home.

Although he had only been away for a few days, he felt as if a century had passed. He began to miss Teacher Iruka, Grandma Tsunade, the warm bed, everything in Konoha Village, and of course, the Nine-Tails, the companion who always accompanied him silently.

He missed Ninetales very much, missed its hearty laughter, and missed its warm embrace.

He finished the last bite of curry, took a deep breath, stood up and went to the depths of the treasure house to find the last few ingredients he needed.

He found a transfer map among a pile of scrolls. It was a huge scroll that was taller than Naruto when unfolded.

The scroll is made of a special canvas, very thick, and has the outline of a human body painted on it, representing the front and back views.

The reason for using the transfer map is that Naruto needs to draw a large number of runes on his body, and there are some places, such as the back, that he cannot see or reach, so he needs to use the transfer map to draw the runes on the map first, and then use chakra to transfer them to his body.

Some transfer maps had runes already drawn on them, but what Naruto needed was a blank transfer map so that he could freely draw the runes he wanted.
