BFTS: Chapter 9
---
To avoid attracting the attention of the ninjas guarding the barrier, only real animals like birds can pass through the barrier without being noticed.
Birds in nature do not have chakra.
Therefore, the ninjas guarding the barrier will assume that the bird is not a transformed ninja or controlled by a ninja, and will ignore it.
Because if the bird is transformed from a ninja or controlled by a ninja, there will definitely be chakra on the bird.
As long as there is chakra, it will inevitably be sensed by the barrier.
This is the terrifying chakra-sensing ability of the five great ninja villages' perception barriers.
Almost no hostile ninja can pass 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, with no chakra in its body.
When entering and leaving the villages of the five great ninja villages, it won't be identified as an enemy invasion by the ninjas guarding the barrier, attracting their attention.
In this way, Akemiya Takuya, who masters the perfect Transformation Technique, can directly infiltrate each village to gather intelligence.
Moreover, transforming into a bird or something similar to get close to hostile ninjas won't make them wary, making it easier to gather useful information.
Furthermore, birds can fly, meaning that Akemiya Takuya, who possesses the perfect Transformation Technique, also becomes a ninja who can fly.
You must know that in the ninja world, there aren't many ninjas who can fly, you can count them on one hand.
In critical moments, being able to fly can be a lifesaver.
So, in a sense, ninjas who can fly already have an innate advantage.
After all, if you're unsure what to do, you can fly away, and the enemy can only watch helplessly as you fly away.
Even in the sea, you can perfectly transform into a fish and swim in the deep sea to avoid enemy pursuit.
The deep sea's atmospheric pressure will automatically prevent any enemy from approaching.
The key is that whether you perfectly transform into a fish or a bird, because there is no chakra, chakra-sensing ninjas can't sense it.
Once you leave their sight, any ninja will have a hard time catching up, making it a great escape tool.
If you use it for assassination, the perfect Transformation Technique is also a great tool, because there is no chakra, it's hard for people to notice and be wary.
It can be said that the perfect Transformation Technique can not only be used for infiltration and intelligence gathering, but also for assassination and escape, making it a perfect fit for Anbu ninjas.
"No wonder Akemiya Takuya wanted to research and create the perfect Transformation Technique, it's truly a ninjutsu that perfectly suits ninjas working for an organization like the Anbu!"
Kenshi thought to himself.
"Such a perfect ninjutsu, it's a shame to leave it like this."
Kenshi's heart moved, and he had already made up his mind to inherit Akemiya Takuya's research and create the perfect Transformation Technique.
It was now the time between the First Great Ninja War and the Second Great Ninja War.
And it was most likely not long before the Second Great Ninja War.
Kenshi didn't know if he would be taken to the battlefield.
But if he could create the perfect Transformation Technique before that,
Then whether he was taken to the battlefield or not, when he was surrounded and had to escape, the perfect Transformation Technique would be his safest escape method.
Mastering the perfect Transformation Technique would greatly improve his safety.
"But such a powerful ninjutsu shouldn't be so easy to create, right?"
Kenshi furrowed his brows slightly, guessing and a little anxiously continued to look through the notes.
As expected, the idea of the perfect Transformation Technique is good, but it's very difficult to achieve.
To transform the Transformation Technique from a visual deception to a perfect Transformation Technique based on material transformation, there are too many difficulties.
Akemiya Takuya first researched the first step of material transformation from the Body Replacement Technique.
As everyone knows, the Body Replacement Technique is actually just a clone technique, just like the Water Clone, Sand Clone, and other clone techniques. It's not a space-time ninjutsu that can swap positions with wood.
Otherwise, Sasuke's Rinnegan ability, "Amenotrejikara," would be too cheap.
In fact, the so-called Body Replacement Technique is just a tactic used in battle to release a clone at the right time to attract the enemy's attention, while hiding oneself and waiting for the opportunity to strike. It's not a true ninjutsu.
Akemiya Takuya was actually researching the principle of the clone technique using wood.
The clone technique in the three basic techniques is different from the wood clone technique in the Body Replacement Technique, or rather, they are not at the same level of ninjutsu.
The clone technique in the three basic techniques is actually just a phantom clone of oneself. In a way, the clone technique is also an application of the Transformation Technique, just a phantom transformation of one's own appearance.
So, the clone technique in the three basic techniques is just a chakra-transformed shape, it has no weight and naturally no attack power.
It can't even move violently, it can only do some simple movements in place, and if it encounters a strong collision, it will shatter like a sand dune, crumbling at the slightest touch.
So, how can you make the clone technique act like a normal person and have a certain sense of impact and attack power?
The answer is to perform the Transformation Technique with wood as the center, allowing the phantom clone to be attached to the wood. In this way, the phantom clone is stabilized by the wood, not easily broken, and through the chakra connection, the clone can gain the weight of the wood.
In this way, when the clone fights and collides with the enemy, the sense of physical impact is more real, making it easier to deceive people.
Akemiya Takuya researched the wood clone to figure out how the wood used chakra to give the phantom clone a sense of physical impact like a real person, and what the connection between the two was.
In the notebook, after researching for a while, Akemiya Takuya figured out the principle of the wood clone.
Chakra is both energy and a special energy channel that can transfer the "weight" of the wood to the phantom clone, and then, with the phantom clone as the subject, give the phantom clone weight.
This doesn't involve material transformation, but it has a hint of it.
"Chakra can transfer some of the characteristics of matter to chakra."
Following this line of thought, Akemiya Takuya replaced the wood with a living bird and performed the Transformation Technique with the bird as the center.
If he could transfer the weight of the bird to the phantom clone,
Then, could he go a step further and transfer the bird's flesh and blood cells and other information to the phantom clone, making the phantom clone also have flesh and blood cells and become a normal living person?
The answer is obviously possible.
But in the first stage, Akemiya Takuya failed to perform the clone technique with a bird, even with a dead bird.
Unlike stable wood, whether the bird was alive or dead, chakra couldn't transfer the "weight" to the phantom clone, forming a stable bird clone.
Without breaking through this step, material transformation couldn't be mentioned.
But this step was too difficult.
The notebook had a large portion dedicated to recording Akemiya Takuya's various experiments in researching this step.
Even so, Kenshi didn't see Akemiya Takuya break through this crucial step until the end.
But he wasn't entirely empty-handed.
Through research and experiments, Kimura had a fairly believable guess.
The reason why chakra couldn't transfer the bird's weight to the phantom clone was because the bird, like humans, had bodily energy and mental energy.
And because chakra itself is a fusion of bodily energy and mental energy.
So, when his chakra entered the bird's body, it was also subtly affected by these two energies.
It couldn't transfer the bird's weight as stably as it could transfer the wood's weight.
To achieve stable output of the bird's weight, Akemiya Takuya guessed that the bird's bodily energy and mental energy needed to be in a stable state.
But that's impossible.
Bodily energy and mental energy are constantly changing, like the water in a flowing waterfall. The water in the waterfall at one moment is different from the water in the waterfall at the next moment, it's constantly flowing and changing.
So, it's impossible to stabilize the bird's bodily energy and mental energy.
If you can't stabilize the bird's bodily energy and mental energy,
If you could make your chakra change synchronously with the bird's bodily energy and mental energy every moment, then theoretically it would be possible to stably transfer the bird's weight to the phantom clone.
But that's also impossible to achieve.
Not only could Akemiya Takuya not do it, but it would be difficult for anyone else to do it.
People can't even accurately sense their own bodily energy and mental energy, let alone the changes in a bird's bodily energy and mental energy.
"It's really difficult."
Seeing this, Kenshi unconsciously shook his head. Putting himself in their shoes, he couldn't do it either. He could only accurately sense his own bodily energy and mental energy changes, but he was powerless to do anything about the bird's.
He continued to read.
After failing at this step, Akemiya Takuya didn't give up, he changed his approach.
