The strength of a puppet depends mainly on two factors.
The first is the maker's skills, including the design of the puppet, the use of mechanical techniques, and even the drawing of sealing runes.
The second, of course, is the materials used to make the puppets.
Especially for high-performance puppets, because they need to draw various rune spells, they must use a lot of chakra conduction materials.
Because these materials can conduct chakra, they have been widely used in important areas such as talismans, barriers, and advanced ninja tools.
Therefore, they have always been regarded as the most important strategic resource by various villages and countries and are very scarce in the market.
When Hideki first taught himself puppetry, he was not like the Sunagakure puppeteers who had the support of a village, so he was choked by these chakra conducting materials for a long time.
He was able to think of using hair to make the handle line, thanks to his past experience...
Even now, many of the materials for his puppets are actually taken from other puppeteers' puppets...
But he is no longer at the stage where he can eat his fill without starving the whole family.
Chakra conduction materials are needed for students' practice, workshop products, and even the upgrade of one's own puppets.
Although once the courses and workshops are on track, the village should provide a certain quota.
But these little materials borrowed from other departments are naturally unable to meet the needs of Xiu Shu's grand blueprint.
So Xiu Shu had to be self-sufficient and try to find more sources of chakra conducting materials for himself.
As for how to find such materials, Xiu Shu was naturally fully prepared.
In fact, a long time ago, the ninja predecessors who used mechanical techniques or sealing techniques had already invented methods to find chakra conducting materials.
According to records in books, materials that can transmit chakra do not exist naturally in the ninja world.
Whether it is chakra metal or animal and plant materials, they are often immersed in high-concentration chakra sources for many years before they acquire the ability to transmit chakras.
The most common high-concentration chakra source is naturally the famous nine tailed beasts.
They like to sleep for decades, and the chakra that emanates from their bodies is enough to allow local animals, plants, and even minerals with a high degree of compatibility to gain the ability to conduct chakra.
Some animals and plants will even quickly evolve new characteristics depending on the environment, and may even become creatures that can refine chakra on their own.
Among the Seven Ninja Swordsmen of the Kirishukakushi, Samehada is the best among them.
Having followed the three-tailed Isobu for many years, it even acquired the ability to actively absorb and transmit chakra.
The method used by ninjas in the past to find new materials was actually very simple. It was to infuse a little chakra into various unprecedented materials.
The quality of the material can be roughly judged based on the difference in chakra conduction performance.
Hideki used the Brain Storm Technique and the powerful chakra control he developed from it to create a more sophisticated detection method based on the work of his predecessors.
He can penetrate chakra into materials to clearly understand the basic physical properties of materials, such as density, ductility, toughness, etc.
More importantly, Hideki could even detect a half-real, half-virtual pulsating substance hidden deep within the material.
After many experiments, Hideki has determined that they are the fundamental reason why the material can transmit chakra.
More importantly, their functions and appearance made Hideki think of the meridian system in the human body...
In fact, after Hideki's verification, the two are indeed very similar, and can even be said to have the same origin.
This discovery, combined with his knowledge of the original work, was like a bolt of lightning to Hideki, who suddenly understood a lot of things.
Chakra is an alien energy that only appeared in the ninja world thousands of years ago.
So it is obvious that before this, it was impossible for the human body to have a meridian system specifically used to transport chakras.
Humans naturally do not obtain the power of the meridian system and chakra like in the TV animation, by relying on the Six Paths Sage to shake hands with each person one by one.
Eliminate all impossible situations, and whatever remains, no matter how unbelievable it is, is the truth!
At that time, all humans were infected with the Infinite Moon Reading and were hung on the sacred tree and gradually transformed into White Zetsu.
Although the two filial brothers, the Six Paths Sage, eventually defeated Kaguya and rescued everyone from the Infinite Moonlight.
But you can't cancel a transformation surgery midway and pretend nothing happened.
Therefore, the human body still has traces of being transformed by the sacred tree, and that is the so-called meridian system.
Even the talents and special abilities of the current ninja clan may be derived from their ancestors who were more highly modified at that time.
The civilians today are the descendants of the less advanced humans of the past...
Therefore, even without the guidance of the Six Paths Sage, humans will sooner or later master the use of chakra on their own.
The Six Paths Sage probably saw this point, so he took the initiative to establish the Ninja Clan, clarify the true meaning of chakra, and try to guide humans onto the peaceful path of mutual understanding through chakra.
Of course, his good intentions were ultimately misplaced.
Although figuring out the secret of how humans master chakra doesn't seem to have much impact on Hideki's current situation.
But at least from then on he was able to look at things related to chakra from a higher perspective, which played a great role in his future research.
But the biggest benefit of this secret now is that it gives Hideki inspiration on where to look for chakra conduction materials.
One of the easiest places to ship goods is the Great Konoha Forest...
The story begins when Xiu Shu was a child.
Like many ninjas, Hideki has been practicing various techniques in this forest since he was a child.
So he knew that the vast Konoha Forest was a paradise of biodiversity, nurturing countless species of animals and plants.
It is said that even experienced hunters with decades of experience always discover species they have never seen before every time they enter this forest.
However, as a time traveler, Xiu Shu discovered a strange aspect of this forest that is difficult for ordinary people to notice.
That is, many plants that should have existed at different latitudes and in different ecological environments in Xiu Shu's previous life can gather together here, showing habits that are very different from those in his previous life.
At first, Xiu Shu didn't take it seriously, just because this was a different world after all, and it was normal for the habits of plants to be different from those in the previous life.
However, after Hideki began to wander around the ninja world, he repeatedly discovered that the plants were growing in the environment they were supposed to grow in, which was not much different from his previous life.
This also made Xiu Shu begin to realize that this forest is unusual...
Later, after he concluded from various books that chakra might allow plants to evolve characteristics that allow them to adapt to their environment, he came up with a bold guess.
First, after Hideki's inspection, he found that although it was very subtle, some of the plants here did have the prototype of a meridian system inside.
Secondly, there is no record in historical records of the tailed beast living here for a long period of time in the past hundred years.
Considering the ability of the sacred tree to transform living things through chakra, the answer is obvious.
However, Hideki still did not make a final decision easily at that time.
He followed the traces of this special plant all the way to explore, and when he finally came to the legendary Valley of the End, he fully confirmed his idea:
Wood Release!
It seems that in the earth-shattering battle of the Valley of the End, Hashirama Senju's Wood Release not only changed the surrounding terrain, but also gave the plants here infinite possibilities.
The reason why the effect of this Wood Release can cover the entire Valley of the End is not difficult to guess.
According to the original work, although Hashirama Senju did eventually defeat Uchiha Madara through the immortal technique, Wood Release, True Thousand Hands, and the Supreme Buddha.
But in fact, Madara's powerful Susanoo was not completely powerless. It actually broke all the thousand wooden hands behind the Buddha statue.
Even judging from the appearance of Hashirama in the back, perhaps even the huge Buddha statue itself would not be spared.
You have to know that Wood Release is not like other Five Elements Release techniques. The wood used in it can last forever.
So it was natural that the broken pieces of the wooden hand were scattered all over the Valley of the End.
The Wood Release Chakra contained in it also dissipated, turning the entire Valley of the End into a paradise for plant evolution...
Since the Divine Tree can transform humans to create White Zetsu, it is reasonable that the Wood Release derived from the Divine Tree can transform plants.
As for those plants that shouldn't exist here, their seeds probably came here many years ago, but because the environment is not suitable for growth, they have been dormant underground for many years.
They were able to survive until now only after being awakened from underground by Wood Release and using chakra to adapt to the environment.
Today, the Konoha Great Forest has the amazing sight of plants from different ecological environments gathered together.
Although most plants have only slightly evolved characteristics to adapt to their environment, the unformed chakra meridians in their bodies prevent them from being used as chakra materials.
But there are still a few lucky ones who change their fate through Wood Release Chakra and become rare plants that can be used as chakra conducting materials.
And Hideki's target is exactly them!
