Although Hideki has confirmed that there must be a large number of rare plants with chakra conduction properties in the Valley of the End.
However, trying to accurately find them among the wide variety of plants is undoubtedly like looking for a needle in a haystack.
Therefore, Xiu Shu had already used the power of the brain storm technique to invent a more efficient screening method.
At this time, he had arrived at an open space on the edge of the Valley of the End.
Hideki first marked his position on the map, and then controlled the black cat that had been exploring the way ahead to jump onto a large rock.
"Then let's start from here and begin the material exploration of the Valley of the End."
Hideki declared in his heart.
Then he placed his right hand in front of his chest and formed the Tiger Seal, beginning to refine more chakra.
As he moved, the chakra lines between him and the black cat began to become clearly visible due to the surge of chakra.
After infusing the black cat puppet with enough chakra, Hideki officially began to use his own ninjutsu.
"Practice: Radar Perception Technique."
The next moment, the lifelike little black cat suddenly stood up with its eyes rolled back, tilted its head back, and opened its mouth to an exaggerated size that was big enough to swallow a basketball.
Immediately afterwards, a series of mechanical parts popped out of its mouth with a click, and finally unfolded to form a pot-shaped antenna device.
Finally, the black cat's head began to rotate 360 degrees at a constant speed, as if it was sending and receiving some signals at the same time...
Although its shape is a bit strange, this is a new invention that Hideki came up with in order to find chakra materials more efficiently.
The inspiration for this new invention actually came from the radar that Hideki had used in his previous life.
In his lifetime, humans had already developed the technology to use geological radar to search for oil and mineral resources.
The principle is to utilize the characteristics that high-frequency electromagnetic waves propagate and attenuate at different speeds when encountering different media. By emitting electromagnetic waves underground and capturing and analyzing the returning reflected waves, the underground situation can be understood.
Hideki's Black Cat radar uses a similar principle.
However, because the machine is looking for materials that can conduct chakra, it emits chakra waves instead of electromagnetic waves.
Yes, chakra is similar to electromagnetic signals and can be transmitted in the form of waves.
In fact, the characteristic of chakra was also mentioned in the original work.
When Pain's Six Paths attacked Konoha, Shizune, after analyzing the black sticks on their bodies, clearly pointed out that the enemy was controlling Pain's Six Paths through chakra waves.
As an aspiring puppeteer, Hideki is naturally envious of Nagato's ability to wirelessly control puppets.
It's a pity that the key black stick is the top-grade chakra conducting material made of Yin-Yang Release, and Xiu Shu has no way to get it.
Although Hideki tried to use other materials instead, he was ultimately unable to replicate the technique due to his limited chakra and sealing skills.
Even if the puppet can be made to move, the obvious operation delay and huge chakra consumption still make this technology temporarily unusable in actual combat.
But Hideki did not gain nothing.
With the help of the Brain Storm Technique, he was able to rely on his strong chakra control ability to figure out a set of techniques for using chakra waves on his own.
Just like radar, Hideki can control the vibration of chakra and freely emit chakra waves of different frequencies and intensities outside the body.
Afterwards, he can also receive and sense the reflected chakra waves to understand the general situation around him.
Although there is no evidence, Hideki seriously suspects that in the ninja world, most of the perception ninjutsu actually uses this principle.
Just like other perception ninjutsu, Hideki's radar perception technique can only detect the surrounding terrain and nearby creatures with chakra fluctuations.
With Hideki's current abilities, it is still difficult to distinguish the subtle changes that occur when chakra is reflected by chakra-conducting materials.
So Hideki had no choice but to use the power of technology to invent this Black Cat Radar.
Its first function is to replace Hideki in performing the radar perception technique, thus preventing him from being ambushed while concentrating on performing the technique.
But more importantly, it also has a built-in chakra signal amplifier, which allows Hideki to easily distinguish the slightest changes in the chakra reflection waves.
The reason why Hideki is confident that he can find chakra conducting materials in this vast Valley of the End with countless species is precisely because of this Black Cat Radar.
Although it is also limited by materials, chakra amount and sealing technology, as well as for considerations of perception accuracy, the detection range of this Black Cat Radar is not large, with a radius of only about fifty meters.
But compared to the clumsy method of the predecessors who went from plant to plant, the efficiency has increased by more than a thousand times!
However, Xiu Shu was not satisfied with this.
From the appearance of this Radar Hunter, we can tell that it was actually a temporary modification of the black cat puppet originally used for combat by Hideki due to limited materials.
As long as he can find more suitable materials, or make breakthroughs in chakra volume and sealing techniques, Xiushu will continue to make better radars and improve the efficiency of material detection.
After all, materials are the foundation of puppetry, and this radar that constantly provides Hideki with new materials is the engine of Hideki's grand blueprint...
At this time, Hideki had just sensed and analyzed the chakra waves that had returned, and was marking the places where he might find something on the map.
Then he changed the Black Cat Radar back to its original form and prepared to inspect each location one by one.
In the first place, Xiu Shu gained nothing.
This situation is not uncommon. When several plants that barely have meridians in their bodies are piled together, it may lead to misjudgment of the beauty of the tree.
The same thing happened at the second and third places, which made Xiu Shu feel a little depressed.
Fortunately, when he arrived at the fourth place, he finally gained something.
What Xiu Shu found was an ordinary-looking nightshade.
However, when he used the chakra line to probe into its interior, he found that there were already one or two formed meridians in its body.
Based on Hideki's previous experience in searching for materials in various places, this is usually enough to allow the plant to exhibit some characteristics that are beyond ordinary plants.
Therefore, according to his classification standards for chakra conducting materials, this nightshade can probably be classified as a Class C plant.
However, when Hideki explored its physical properties through chakra, he did not find anything special about it.
So Xiu Shu just marked its location on the map and picked some fruits and branches, waiting to do further tests after returning.
In the following time, Xiu Shu carried out the boring detection work like this.
After checking the marked locations, he moved to another place to explore again, and then continued to check, repeating this process over and over again.
Since this is in the wild after all, Xiu Shu must retain enough chakra to deal with various emergencies, so it is estimated that he will only conduct ten detections at most.
It's a pity that Xiu Shu's luck in lotteries is not good, and there is no guaranteed prize in these ten consecutive draws...
So many times, what he found were plants like those in the first few places, which could only be ranked E in his material classification standards and could not be used as chakra conducting materials at all.
There are also a few plants that can be classified as D-level plants, but they also cannot be used as chakra conducting materials. At most, we can see if we can find a place where they can be used based on their evolved characteristics.
In fact, a C-level plant like Nightshade is already a very good harvest for Hideki.
It was not until he checked the results of the ninth detection that Xiu Shu finally showed a hint of excitement.
Because this time, what he sensed was not on the ground, but buried underground.
If it wasn't a rare plant with meridians in its roots, then what was buried there might be what Hideki was looking forward to...
You should know that after the Thousand-Armed Buddha statue was broken into pieces by Uchiha Madara, it was scattered all over the Valley of the End.
The Wood Release Chakra within it escaped and created this paradise of plants.
But in fact, the fragments themselves are also rare treasures.
As a fragment of a Buddha statue made with Senjutsu Chakra, it goes without saying that it has extremely excellent physical properties and chakra conduction capabilities.
Even if its performance has been greatly reduced due to the passage of time, it is still a good material for making puppets for Hideki now.
So Xiu Shu naturally came to the place where the wood block was suspected to be, and began to control the black cat puppet to start digging.
The thing was not buried too deep, so it was dug out by the black cat in less than a minute.
Although it looks like just an ordinary piece of wood the size of a fist.
Xiu Shu, however, picked it up as if it were a treasure and carefully wiped off the remaining dirt on it.
Then he injected chakra into the wood, and after confirming that it was what he expected, an excited smile finally appeared on his face.
However, at this moment, a huge change suddenly occurred.
Suddenly, a puppet with the appearance of a praying mantis and an extremely ferocious look jumped out from the bushes nearby!
Immediately afterwards, a sharp cold light flashed by.
Before Xiu Shu could even react, the head, still with a smile on its face, had already flown high into the air.
The next moment, blood spurted out from the broken neck. When the head fell to the ground, a large area of land had been dyed bright red...
