Konoha, reported by the Fourth Hokage at the beginning

In the future ninja world, his Sarutobi clan will be the strongest clan.

Thinking about the various benefits that would come from obtaining the art of immortality, the third generation looked calm on the outside, but extremely excited on the inside.

He completely forgot that the art of spiritualization was not a secret art that he could learn. Even if he obtained the art of immortality such as soul possession, he could not use it, and it would all be in vain in the end.

All I can say is that no one can remain calm in the face of eternal life, and no one wants to give up this opportunity of eternal life to others.

The third generation did not tell anyone about his guess, and he was not going to let anyone stop him from obtaining the art of immortality.

At this time, Kimura Yao was at home.

Li Yao ate a bowl of noodles and then went to the room of his predecessor's parents.

Bang... Li Yao opened the large cabinet in front of the bed and began to rummage through it, trying to see if he could find any books or notes related to ninjutsu training.

In the memories of his previous life that Li Yao inherited, his parents had never taught him any ninjutsu. The only ninjutsu he knew now was the Three Body Techniques taught in the Ninja School.

With Li Yao's current chakra control, he can perform the Three Body Technique instantly without any hand seals, and the effect is better than that of others.

He performed it during the practical class this afternoon.

One hundred percent absolute control over chakra gives him absolutely powerful ninjutsu talent.

After performing the seal of the Three Body Technique once, Li Yao memorized the changes and fluctuations in the chakra of the Three Body Technique when performing the seal.

Then he could easily perform the Three Body Technique by directly controlling the relevant chakra changes in his body without making any hand seals.

Not only is it fast, but the effect is no different from the Three Body Technique he performed himself.

It can be said that as long as the ninjutsu is not too complicated, Li Yao can release it without any seals, and the effect will not be weakened.

With such talent, Li Yao naturally wanted to learn more ninjutsu.

He is alone in this world and feels insecure. Learning more ninjutsu and increasing his strength will give him more security.

Therefore, Li Yaodu is still maintaining a state of condensing chakra, not letting go of any physical and mental energy that naturally overflows from his body, in order to quickly improve his strength and have enough sense of security.

This is also the reason why the Anbu bugs cannot sense any trace of chakra on his body, because he is condensing chakra every moment.

It was also because of this that Li Yao aroused Minato's suspicion in the first place.

At this time, Li Yao didn't know that he had been targeted by the Anbu, and the Third Hokage was on his way to capture him.

Li Yao continued to rummage through the cabinet. He didn't have high expectations at first, but he actually found a ninjutsu notebook at the bottom of the cabinet.

Judging from the signature on the notes, they are the notes of the predecessor's father, Takuya Kimura, studying ninjutsu.

Li Yao opened the notebook with curiosity.

Thanks to the help of his remaining memories, Li Yao had no problem with the writing and language of this world, and he could read and understand everything in the notes.

"Transfiguration?"

Li Yao immediately lost interest. It seemed that they were only studying the transformation technique among the three basic body techniques. What was so good about studying such a low-level ninjutsu?

With doubts in his heart, Li Yao continued to read.

Then he smiled with interest.

In his notes, Takuya Kimura divided the transformation techniques into different levels.

As envisioned by Takuya Kimura.

Low-level transformation techniques are just an illusion transformation, which uses chakra to create an illusion that covers oneself, thus forming a visual deception transformation effect.

In fact, there has been no change in my body, but I can feel the abnormality just by touching it with my hand.

This type of phantom transformation technique, when practiced and applied to the extreme, is the level of the dark side's unique invisibility technique. It covers itself with the surrounding environment through phantom, thus achieving the effect of chameleon-like invisibility.

This kind of invisibility technique can be said to be a standard feature of the dark side. It is simple and practical, and if used well it can sometimes play a crucial role.

Seeing this, the note seemed to be written in the tone of an ANBU ninja, and a guess suddenly flashed through Li Yao's mind. Could it be that the parents of his previous life were both ANBU ninjas?

It seems... it's possible when you think about it.

According to the remaining memories of my previous life, my parents were basically not at home, sometimes even disappearing for a month or two.

This horrific attendance rate is not what a normal ninja should have.

Moreover, from the remaining memories, his predecessor rarely saw his parents interacting with other ninjas, and he had never heard of any ninja who was very familiar with his parents.

Because only Anbu ninjas who need to hide their identities would do this.

Thinking about it this way, Li Yao became more certain of his previous life's parents being Anbu ninjas.

"Anbu... no wonder he died."

Li Yao sighed inwardly, the death rate of Anbu is much higher than that of ordinary ninjas, he would rather die than join Anbu in the future.

Retracting his thoughts, Li Yao continued to read Kimura Takuya's notes.

Low-level transformation techniques are not very useful in combat, and any ninja with a little experience can see through them at a glance.

At this time, a new transformation technique emerged based on the low-level transformation technique.

This transformation is no longer an illusion, but has the tactile perception of a entity.

If you transform into a big stone or water, you will really have the tactile sensation of stone and water.

This type of physical transformation is more deceptive than the illusion transformation.

However, it still has major flaws and is not a perfect transformation technique.

Whether it is a phantom transformation or a physical transformation, the principle is to use chakra to transform an object into something that covers oneself, thereby achieving the effect of visual transformation.

To put it bluntly, it is still a visual deception, not a real transformation.

Takuya Kimura wanted to create a real transformation jutsu, where he could actually transform into a stone or a bird, a fundamental change from matter to life, without any trace of chakra.

Even if one used the Hyuga clan's Byakugan, which could see through the flesh and see the flow of chakra in the body, to see a perfect transformation into a bird, one could only see a real bird, and could not see any traces of chakra that had been transformed by the transformation.

"If this perfect transformation technique can really be achieved, it would be no different from Sun Wukong's 72 transformations!"

Li Yao murmured to himself, shocked by Kimura Takuya's idea. He couldn't say how much of an improvement in combat it would bring if this perfect transformation technique was really created, but it would definitely be a huge improvement for the Anbu ninjas responsible for assassinations and gathering intelligence.

In his notes, Takuya Kimura talked a lot about the advantages and application scenarios of the perfect transformation technique.

First of all, it would be easy to break through the perception barrier.

The five major ninja villages are all covered by their own defensive perception barriers.

Except for a temporary passage at the gate that can be opened and closed, other places are firmly locked by the perception barrier.

The barrier passageway in and out of the gate is guarded by ninjas at all times, day or night.

Anyone entering or leaving, whether it is a caravan or a ninja from the ninja village, must have a relevant pass. The ninja on duty will check it and temporarily open the barrier passage before they can pass.

In essence, the Ninja Village is actually a large, comprehensive military base with tight defenses.

In this situation, it is difficult to invade secretly.

Anyone entering or exiting without permission will trigger the perception barrier and be sensed by the ninja in charge of the barrier.

In the past, when the Anbu secretly invaded the five major ninja villages to collect intelligence, they would capture the enemy ninjas outside and then use various threats or ninjutsu to seal their memories.

In short, the main purpose is to instigate rebellion.

No Anbu can directly sneak into the other side's ninja village to collect intelligence.

Because of the existence of the perception barrier, without the corresponding barrier password, it is impossible for any ninja to pass through the perception barrier silently.

Especially for ninjas with chakra, even a ninja like Li Yao who does not emit a trace of chakra from his body, cannot escape the perception of the perception barrier. The strength of the chakra in his body will be clearly sensed, attracting the attention of the ninja on duty at the barrier and raising the alarm.

Chapter 9 The Difficulty of Developing a Perfect Transformation Technique

If one wants to avoid attracting the attention of the ninja on duty at the barrier, only real animals such as birds can pass through the barrier without attracting attention.

Birds in nature do not have chakras in their bodies.

Therefore, the ninjas on duty who sensed the barrier would assume that the bird was not transformed by a ninja or controlled by other ninjas, and would ignore it.

Because once the bird is transformed by a ninja or controlled by a ninja, there must be chakra in the bird.

As long as chakra exists, it will be sensed by the barrier.

This is the perception barrier of the five major ninja villages, and its ability to perceive chakra is terrifyingly strong.

Almost no hostile ninja could break through silently.

But once you have the perfect transformation technique, everything becomes easy.

The bird transformed by the perfect transformation technique is a real bird, without any trace of chakra in its body.

When you freely enter and exit the five major ninja villages, you will not be identified as an enemy invasion by ninjas who sense the barriers and thus attract attention.

In this way, Takuya Kimura, who has mastered the perfect transformation technique, can go directly into each village to collect information.

Moreover, if you transform into a bird or something like that to get close to hostile ninjas, they won't be alert, making it easier to collect useful intelligence.

Furthermore, the bird can fly, which means that Takuya Kimura, who possesses perfect transformation skills, can also become a ninja who can fly.

You have to know that in the world of Naruto, there are not many ninjas who can fly, and they can be counted on one hand.

At critical moments, being able to fly can save your life.

So a ninja who can fly is, in a sense, inherently invincible.

After all, when you are in doubt, you can fly away as a sign of respect, and the enemy can only watch you go away helplessly.

Even in the sea, it can perfectly transform into a fish and swim in the deep sea to avoid being tracked by the enemy.

The atmospheric pressure of the deep sea will automatically prevent any enemy from approaching.

The key point is that no matter whether it is a perfect transformation into a fish or a bird, because there is no chakra, the chakra-sensing ninja cannot sense it.

Once out of sight, it is difficult for any ninja to catch up, making it a great weapon for escape.

If used for assassination, the perfect transformation technique can also be a powerful weapon. After all, without chakra, it is difficult for people to be alert.

It can be said that the perfect transformation technique can not only be used for invasion and intelligence gathering, but is also very useful for assassination and escape.

Gathering intelligence and escaping assassinations are the essential duties of Anbu ninjas.

Perfect transformation technique, perfectly compatible with Anbu ninja.

"It's no wonder that Kimura Takuya wants to research and create a perfect transformation technique. It is indeed a ninjutsu that is very suitable for ninjas from an organization like the Anbu!"

Li Yao sighed in his heart.

"It's a shame to stop such a perfect ninjutsu like this."

Li Yao's heart moved, and he had made up his mind to inherit Kimura Takuya's research and create a perfect transformation technique.

This is the period between the First and Second Ninja World Wars.

And there is a high probability that the Second Ninja World War is not far away.

Li Yao didn't know whether he would be taken to the battlefield.

But if we can create a perfect transformation technique before that.

So no matter whether he was brought to the battlefield or not, when he was surrounded and had to escape, the perfect transformation technique would be his safest means of escape.

If he could master the perfect transformation technique, his life safety would be greatly improved.

"But such a powerful ninjutsu shouldn't be that easy to create, right?"

Li Yao frowned slightly and guessed, then continued to look through his notes with some trepidation.

As he expected, the idea of ​​perfect transformation was good, but it was difficult to realize.

There are too many difficulties in transforming the transformation technique from a visual deception technique to a perfect transformation technique of material conversion.

Takuya Kimura first studied the first step of material transformation from the perspective of substitution techniques.

As we all know, the substitution technique is actually just a kind of clone technique, just like the water clone, sand clone and other clone techniques. It is not a space-time ninjutsu that can replace positions with wood.

Otherwise, Sasuke's exclusive ability of the Six Magatama Samsara Eye, "Heavenly Hand Power", would be too cheap.

In fact, the so-called substitution technique is just a ninja tactic of finding the right time in battle to release a clone to attract the enemy's attention, hiding oneself and waiting for an opportunity to strike. It is not a real ninjutsu.

What Kimura Takuya actually wanted to study was the principle of the clone technique using wood.

The clone jutsu among the three body techniques is different from the wooden clone jutsu among the substitute techniques, or it can be said that they are not ninjutsu of the same level.

The clone technique in the three body techniques is actually a series of phantom clones of oneself. To some extent, the clone technique is also an application of the transformation technique, except that the phantom clone is one's own appearance.
