The principle is not difficult to understand, but the scorpion is very difficult to perform, whether it is to compress the wind escape chakra ball or to spin the chakra ball fast enough, it is difficult to do.

There was already a large crater on the ground that had been smashed by the half-formed spiral pill, and the scorpion's chakra control was much stronger than that of Naruto in the original book, and it seemed that the scorpion could have skipped the first stage directly.

"Scorpion, this is for you." Uehara put the fidget spinner on his index finger and blew it lightly, and the spinner immediately began to spin.

The scorpion also stretched out its small hand and took the top with its fingertips, and the top rotated very smoothly, and the speed was not affected in the slightest during the handover.

The scorpion puffed out its mouth and took a deep breath, with the help of the condensed wind chakra blowing towards the fidget spinner, with the three of them as the center, suddenly a sandstorm broke out, and the little worm complained about the scorpion even more unhappily.

The spinning top that was originally firmly nailed to the fingertips had the blessing of the Wind Escape Ninjutsu, and it could no longer be kept stable, and instantly flew obliquely into the air like a shuriken, and then the sky suddenly darkened, and the fidget spinner flew out and was blocked straight back by the scorpion's puppet crow bell.

The surface of the puppet crow was shattered, Uehara's fidget spinner was still not damaged, and the scorpion frowned and checked his puppet, "Your ninja is good." ”

"This is a ninja made by the Wind Demon Clan," Uehara smiled, "In addition to the Wind Demon Clan's superb shuriken skills, they also have a very peculiar metal formula. ”

"I think the Wind Demon are similar to you puppeteers in some way, and they also like to make all kinds of devices to craft and improve shuriken......"

"Special metal?" The scorpion was keenly aware of the key information in Uehara's words.

The Ninja World has similarities to other fantasy worlds, where Ninjas have Chakra metal similar to Mithril. Shinobi made of chakra metal has excellent chakra conduction characteristics, which greatly increases the strength and lethality of the ninja tool, and a ninja made entirely of chakra metal is ridiculously expensive.

In the original book Shippuden, Konoha's ninjas also assigned themselves a team of small palm blade Feiyan to Ape Fei Asma, the second generation of officials. For the vast majority of other ninjas, it was almost impossible to get their hands on a weapon made entirely of chakra metal.

Chakra metal is so scarce that the Stormlords have been working hard to find a replacement. More metal formulas with different properties are derivatives of the research process, and thanks to these research results, the quality of the shuriken of the five major ninja villages is the highest.

In previous lives, materials science was a vital part of basic science and was at the heart of the entire industrial system. Uehara values the Wind Demon Clan, but in Iwakure Village, the most important ninja of the Wind Demon Clan after the war is the teacher in charge of teaching shuriken.

Guys like the ninjas of the Wind Demon Clan, in Uehara's thoughts, should protect them well and do research.

Uehara was in a daze, and the scorpion stood up and tried to wake him up by slamming his fist on the head.

"Scorpion," Uehara suddenly came back to his senses, "the Wind Demon Clan has a lot of interesting metals, but the production is low. Probably they didn't need to make anything other than shuriken. ”

"I have a companion from the Wind Demon Clan, and he will probably become the patriarch of the Wind Demon Clan soon." Frog guy, it's been a long time since the war ended, and so has the Wind Demon Fengjia.

"I want to facilitate the transaction of a large number of special metals between the Sand Hidden Village and the Wind Demon Clan," I am probably going to make a lot of money, Uehara Ju is happy, "This is about a 100 million yuan order, Scorpion, can you help?" ”

The exploration of the spiral pill has come to an end for the time being. Because of Uehara, the conservative and self-enclosed Iwakuin Village began to actively intervene in the war and the affairs of neighboring countries in the Second Ninja War, especially when the war situation between Konoha and Cloud Ninja was anxious, the Wind Demon clan alone provided a large number of shuriken to Cloud Ninja.

The wealth gained in a war is the sum of the income of the entire Wind Demon Clan in the past five years.

Uehara, who contributed to the export of Iwakure's armaments, naturally gained the friendship of the Wind Demon clan. Therefore, dumping a large amount of special metals into Shayin without selling technology will probably not be resisted by the Wind Demon clan.

In Shayin Village, or the entire Land of Winds, supplies are scarce. Judging from the map, the Wind Country has the most extensive territory among the five ninja countries, but most of the Wind Country is a desert environment, and the material output is barely within reach.

Uehara temporarily offered to provide the village with all kinds of metal supplies at a lower price, and the quantity was not limited. His proposal was taken seriously by the three generations of Kazekage who had just rushed back to the village.

The Land of Wind and the Land of Fire are close together, the Land of Wind is barren, and the Land of Fire is rich in products, and the Land of Wind is heavily dependent on the Land of Fire to buy supplies. And the Sand Hidden Village is more or less dependent on the Fire Country in terms of some materials, the first two generations of the Wind Shadow have been seeking change, and their daimyo have the same worries, if the Wind Country and the Wind Hidden Village continue to weaken, and the Fire Country and Konoha continue to be strong, probably the Wind Country will eventually become a vassal of the Fire Country.

Long before the Second Ninja War, a large number of shuriken and other ninja gaps in the Sand Hidden Village were entrusted to the distant Iron Country to make them on their behalf, and Konoha was not chosen.

After the end of the Shinobi War, the Iron Country was completely destroyed, and the Sand Hidden Village turned its attention to the Ninja Village, a craftsman who made more sophisticated ninja tools.

And Uehara's sudden suggestion is something that the high-level of Shayin Village deserves serious consideration.

"The Wind Demon Clan's location is not in Iwakuin Village, and their relationship with Iwakuin is more like a semi-employment relationship. Instead of during wars, the Wind Demon can sell Ninja Equipment to countries other than the Land of Earth. Shuriken, of course. ”

Since Uehara's first visit to Fengyin Village, Uehara once again held formal talks with Fengyin's high-level leaders on more important occasions.

"As for what Kazekage-sama said, I only want to buy shuriken and don't need metal raw materials, I don't think this proposal is okay." Uehara glanced at Chiyo on the left hand side of Kazekage, and he nodded slightly, "It was originally for the sake of my friend the puppet of the Red Sand Scorpion that I decided to sell the metal raw materials. ”

"Although the Sand Hidden Puppet Army has been destroyed, if you want to rebuild the Puppet Army. A large number of raw materials with properties that are close to chakra metal are more powerful than the puppets that will make Sand Yin's new creation, right? ”

Uehara's words, no one answered him.

The village of Sand Hidden has abolished the formation of puppet troops.

The final order was only a small twenty tons of metal. Half of this was purchased by Chiyo's mother-in-law and was prepared for scorpions.

……

The scorpion's puppet has a texture like wood, but it is hard beyond imagination, and Uehara asked him, his puppet is really made of wood using sealing techniques.

"Scorpion, suppose your puppets were all made of chakra metal, how powerful would it be?" Uehara showed the scorpion a grand prospect, "Sturdy, light, and good for chakra, you don't need to make complicated brackets to control the puppet, you just need chakra to be transmitted to the part that needs to make him move......"

"Is there anything special about this metal?" The scorpion and the bug were in the basement, each holding a few metallic marbles in their hands.

"Well, bouncy marbles." Uehara himself didn't know what purpose this was a special ninja made by the Wind Demon clan, "This material of metal has the hardness of metal and the toughness of rubber at the same time"

"No, look."

Uehara grabbed a marble and slammed it against the wall.

Bang bang......

After bouncing back and forth on the left and right walls a dozen times in a row, the marbles finally trickled down the floor.

And those original wooden walls, the cracks of the wooden planks have been smashed all over the place, as if they have been torn down.

Uehara felt that this inexplicable ninja was probably good on hard ground, or after the enemy was surrounded by the earth flow wall, he poured marbles into the chakra and threw them in, killing him......

The little worm took out his glass marble and smashed it gently, shattering the pure red glass ball he liked so much. The little worm hurriedly put away the marbles, and he could already think of the grand occasion of smashing all the marbles of other friends when playing a game.

The marbles seemed to be funny, and the scorpion restrained himself from bouncing marbles around the wall like a bug, which was too silly.

The Wind Demon Clan, the Scorpion became interested in this ninjutsu family that was famous for its shuriken skills.

The Spiral Pill that interrupted the study began to continue, and last time the scorpion used a very ordinary wind escape ninjutsu, just like the blowing foam technique used in the battle against Sasuke in the battle between Danzo, and used the wind speed to accelerate the shuriken to a terrifying level, so as to achieve an extremely strong killing purpose.

After the normal Wind Escape Technique and the fidget spinner, the stability of the top is destroyed.

And this time, the scorpion used the technique of the spiral pill that Uehara said.

First put the fidget spinner in the palm of the hand, and then a large number of wind escape chakras appeared between the palms, and then, as the chakras gathered more and more, and gradually became compressed and began to rotate, the spinning top also rotated, and turned faster and faster, until the four corners of the fidget spinners flew into several fast black lines.

Eventually, after the Spiral Pill stabilized, the black line caused by the optical illusion became one.

After compressing the chakra to the limit of what can be done, the chakra ball that is compressed and given a high-speed rotation seems to have a great impact on the retention of the chakra, gradually reducing the delivery of the chakra, only maintaining a small amount, but the chakra ball has not dissipated for a long time, and the fidget spinner is still spinning, and it is far from stopping.

Eventually, the scorpion restrained the Spiral Pill in his hands, and the three of them watched him spin together.

It is said that when a cat falls from the sky, its feet always land first, and when a slice of bread coated with cheese falls from the sky, the side coated with cheese lands first.

So, the cat and the bread slice were wrapped together with tape and pushed off the table, and then the cat and the bread slice couldn't tell who landed first, and kept tossing up and down in the air for an infinite number of times. In this way, the legendary perpetual motion machine was born......

A minute passed, and the fidget spinner did not change anything, if the spiral pill was a big apple, the fidget spinner was like an apple core, and the dynamic spiral pill reached a strange balance without being affected by the high-speed fluctuating wind chakra flow.

As for the ideas such as the Gemini Spiral Pill that Uehara and his friends are working on, the stability problem has not been solved.

Ten minutes passed.

Twenty minutes and thirty minutes also passed quickly, and Uehara was a little confused.

The scorpion finally got annoyed, and he interrupted the delivery of all the chakras, then lightly placed his fidget spinner on one of the cones.

……

It's been thirty-seven minutes, and the three of Uehara and the scorpion worm are holding their chins and looking at the knuckle spinning top, and it's still meowing!

"Scorpion, I probably know how to condense a spiral pill that can be held in my hand and thrown out when needed."

Giving the Spiral Pill a mechanical core can reduce the difficulty of controlling the stability of the Spiral Pill and make the Spiral Pill fly around his fingertips, which is what Naruto can only do by turning on the Nine-Tails mode in the original book.

"What comes to my mind is that the Wind Escape Ninjutsu can replace many parts of the puppet," the scorpion's eyes flashed with confidence, "In the joint part of the puppet, there is no need to deliberately pursue any ingenious design and precision." ”

"You don't even need controls at the joints, you just need a stable enough wind chakra."

"You mean...... Does Wind Escape Replace Bearings? "Is it similar to the principle of magnetic levitation? Wind escape separates the friction between the brackets, and directly has wind escape and wind pressure to adjust the puppet's movements......

Uehara remembered that in a considerable part of the science fiction setting, advanced civilizations can directly manipulate energy. And the ninja's escape technique seems to be the energy itself.

Being able to directly create a river embankment with Tu Dun Chakra and Tu Dun Ninjutsu does not need to develop a series of heavy industrial equipment.

"Bearings? What is that? The scorpion was puzzled.

At this time, with a ding, Uehara turned his head to look, and the fidget spinner finally stopped.

A fidget spinner that had been spinning for thirty-nine minutes and had turned an unknown number of times was the beginning of the same magic transformation puppet technique of the Scorpion and the Uehara Demon Transformation Spiral Pill.

……

Kazekage didn't believe that Uehara said that he could get in touch with the Wind Demon Clan, and then he could directly reach an order for special metals, so he sent a ninja to Iwakuin Village in the name of Sand Hidden Village.

After the envoy Sha Shinobi said his intention, he was sent directly by Onoki from the shadows to the Wind Demon Clan.

What Uehara said is true, these little things, the Wind Demon Clan can make their own decisions.

Asked if it was feasible for the scorpion to make a giant puppet made entirely of steel, "What should I do if I encounter a Thunder Ninja of the strength of White Fang?" ”

Oh, no wonder the scorpion puppets would rather use hard wood than metal.

"No, Scorpion." Uehara frowned, his Gundam No. 1 might be dying, "There must be a way to deal with it." ”

"It's true that metals conduct electricity easily, but it's just as easy to conduct electricity away, right?"

The outer shell is made of reinforced wood like a scorpion, and the core of the internal control is made of metal? But this is also not good, if you encounter a ninja of the strength of White Fang, as long as the puppet is slightly damaged, the entire puppet will be paralyzed.
