I use the ninja world to help me cultivate immortality

"Super Strength Technique? I've been craving this physical technique for a long time, but I had to give it up because it required too much control over chakra. Now I can give it a try!"

Naraku didn't feel tired after recording various things for many consecutive days. Instead, he kept full of energy and enthusiasm.

At this time, Naraku, who had already entered the stage of recording physical techniques, suddenly brightened up when he recorded one of the physical techniques.

This physical technique is the "Super Strength Technique" passed down by the Senju clan.

"Super Strength Technique" is a very special physical technique.

Unlike conventional physical techniques, which use physical skills, the skill of "Super Strength Technique" is reflected in the control of chakra.

Through precise control of chakra, and then concentrated burst of chakra, an amazing super strength is formed.

This is the way to use "Super Strength Technique".

Of course, it's easy to say, but it's very difficult to do it.

For example, no one in the root organization with this inheritance has ever mastered this physical technique.

It's not that no one in the Root organization wants to learn this physical technique.

No one knows how to do it, but no one has been able to learn it.

There is a typical figure like Tsunade.

Before Naraku awakened his past life memories, he also thought about learning "super strength technique", but in the end, like everyone else, he failed.

But now.

With the improvement of his understanding, his control over chakra has also improved by leaps and bounds, and his confidence has naturally increased.

He plans to start with "super strength technique" in terms of physical technique.

After recording "super strength technique", Naraku continued to be busy.

Unknowingly, illusion and physical technique were also successfully conquered. Next, Naraku came to the secret technique area.

There are also many secret techniques collected.

There are secret techniques such as "Super Beast Fake Painting" that were taken from the outside world, and "Beast Simulation Ninja Technique" that came from the Konoha Ninja Clan.

Naraku took out a secret technique from the nearest bookshelf, and saw that the name marked on the scroll was the "Shadow Secret Technique" of the Nara clan, one of the Konoha ninja clans.

"This secret technique seems to be missing a part"

Naraku was not recording without thinking, and he also pondered while recording.

When recording the "Shadow Secret Technique" in his hand, Naraku suddenly frowned and noticed a problem.

The improvement of his understanding made Naraku's thinking more acute.

It's not that he had never read the "Shadow Secret Technique" before. After all, secret techniques are stronger than ordinary ninjutsu in many aspects.

It's just that the difficulty of practicing secret techniques is often higher than ordinary ninjutsu, so Naraku gave up after trying and failing.

Similarly, he didn't find any problems in the process of trying.

However, at this time, with the increase of understanding, Naraku was very keen to realize that there was a problem with this secret technique.

To be prepared, it's not that there is a problem with the "Shadow Secret Technique", but that there is a problem with the "Shadow Secret Technique" recorded in the scroll in his hand.

After a little thought, Naraku did not come to a conclusion immediately. Instead, after recording, he took the next secret technique.

This time it was still the secret technique of the Konoha Ninja Clan, and it happened to be the "Heart Turning Technique" of another member of the Ino-Shika-Chou clan, the Yamanaka Clan.

"This secret technique also has the same problem!"

After reading it, Naraku gave an evaluation, and then continued to flip through other secret techniques.

One secret technique after another was recorded.

Because secret techniques are even rarer.

Even if the complexity is still above ordinary ninjutsu, Naraku only took one day to complete the recording of all the secret techniques.

After recording these secret techniques, Naraku rubbed his temples and felt a little helpless.

"These ninjas also used their brains when they offered their secret techniques!" Naraku sighed in his heart.

Since Danzo put the secret techniques out, it is impossible for him to hide them.

So the problem with the secret technique can only come from the person who provided the secret technique.

After watching all the secret techniques, Naraku discovered a phenomenon.

That is, all the secret arts outside the village have very complete records of inheritance.

On the contrary, the secret arts from the village have more or less problems.

These problems are very obscure.

It is not that people cannot practice at all, but it greatly increases the difficulty of practice.

In simple terms, it is like a piece of the core of a puzzle is missing, so if you want to complete the puzzle, you need to fill it yourself.

Combined with the secret arts from the outside world, Naraku easily completed the reasoning.

That is, the ninjas of Konoha, although they contributed their own secret arts as a gesture of submission when they joined Konoha, but the secret arts they contributed were retained.

In this way, Naraku was surprised but not surprised.

For the ninjas who are not bloodline limit inheritance, secret arts are the foundation of their clan.

Even if the village has a treaty not to leak secret arts, the ninjas will definitely not fully trust them.

Therefore, it is very normal to keep something private, and it is also human nature.

"Forget it, it's good enough to get most of the information about these secrets. It will take more time to study them later."

Although Naraku felt a little helpless about the incompleteness of the secrets, he quickly adjusted his mentality.

It's all free anyway, so getting a part of it is also a profit.

What's more, he was going to leave Konoha in the future. When he thought that the secret techniques carefully passed down by the ninjas of Konoha would become the foundation for his own development in the future, Naraku felt even better.

Naraku, who was in a better mood, stretched himself. When his body made a series of bone-crunching sounds, he glanced at the bookshelves around him, and finally looked in a certain direction of the database.

Crossing the bookshelves blocking the middle, Naraku looked in the direction where there was a tightly closed iron door.

At the same time, there was a guard of the Root Organization on each side of the iron door.

"Now only the techniques in the Sealed Book have not been recorded." Naraku quickly retracted his sight and walked towards the exit of the database.

The Sealed Book is the most core part of all the techniques inherited by Konoha.

But in the Root Organization, there are still rubbings placed by Danzo.

However, unlike other techniques, no matter how much Danzo believes in the control of the "Seal of the Tongue", he has made certain restrictions on the inheritance of the Sealed Book.

If you want to learn the techniques in the Sealed Book, you have to become a formal member.

And learning is not completely open, but you can only choose one.

If you want to learn more, you can only continue to improve your status, such as becoming a captain, or even Danzo's right-hand man.

The techniques of the Sealed Book are naturally very tempting.

But Naraku is not going to end his comfortable training environment now.

So he can only consider the techniques in the Sealed Book later.
