I have to say that the human puppet technology is indeed a great invention in the ninja world, and it can even rank among the top three in Nara's cognition.

It is even said that if the scorpion can develop an artificial intelligence or something like that, the puppet will completely get rid of the artificial control of the chakra line,

That's really the first science and technology in the ninja world,

When the time comes, in terms of combat power and potential, it will be far beyond the reincarnation of the filthy earth.

When the time comes, invent a three-headed and six-armed human puppet Gundam, the left side of the magnetic escape, the dust escape, the right hand boiling escape, explosion escape,

In the middle, according to two pairs of kaleidoscopes to write wheel eyes, plus a pair of reincarnation eyes,

That's really a big killer in the ninja world.

"Huh?!"

Nara suddenly made a move, dismantling the head of the three generations of puppets, and took out a ball with blue light.

"That's the most important thing..."

"Chakra nucleus..."

Nara's perception slowly dips in,

"Part of the soul as raw material..."

"What an amazing idea and means..."

At this time, Nara was really shocked, is this kind of technology really not illegal?!

How can it be extracted from the soul of a man,

"Maybe the background of the sand ninja is still more than people expected..."

"After all, Sand Shinobi still has a forbidden technique like reincarnation,"

Nara doesn't think that the skill of manipulating souls can be completed by relying solely on the ingenuity of the scorpion.

Do you really think that the scientists in the ninja world are all gray wolves?

Any forbidden technique about the life and death of the soul is piled up by countless human lives and countless human experiments.

With the age of the scorpion, it is impossible to achieve such an accumulation,

"And, what is the material of this chakra nucleus itself?"

Nara Tsukasa kept stroking the chakra core of the three generations of Kazekage, as if looking at a work of art,

"It can actually carry a soul..."

"It also contains a lot of chakra energy,"

Nara was interested,

"Seems to be some kind of ore that I can eat..."

"Hahahaha!"

A burst of laughter suddenly came from the scorpion's mouth,

"In the end, I won!"

"For so long, the toxins I put in the air have fully worked!"

"This is a poison that even the three generations of Wind Shadow can't resist!"

“......”

Nara was silent, as if this genius puppeteer had some misunderstanding of his strength,

Or still have some kind of childish expectations,

From the battle to now, after so long, I haven't even had the slightest reaction to poisoning, so naturally it is impossible to be affected by the toxin.

"It's useless...."

Pharmacist Ye Naiyu was kind enough to explain,

"With his physique, most of the toxins have no effect..."

"And he seems to have some kind of subtle ability to control his body..."

"It can isolate toxins from the outside world..."

Nara looked at her in surprise when he heard this,

'You can see it...'

'The attainment of medical ninjutsu is quite high...'

'Moreover, the scorpion's venom doesn't seem to have much effect on her....'

But the kindness of Yakushi Ye Naiyu seems to have done something bad, and the scorpion who heard the truth was completely depressed and sat on the ground weakly,

Nara decided that he no longer cared about the scorpion, but his figure flashed and disappeared in place.

Immediately after, he appeared in the mine where the scorpion was lurking before,

I saw that there was a dim light inside, which made people barely recognize the scene inside.

Broken human tissue, various puppet parts, and handwritten experiment logs....

The smell of blood and the dampness of the mine is mixed inside, and it looks particularly terrifying.

Apparently, Scorpion has transformed this place into a small puppet laboratory, where he experiments day and night.

Nara didn't think anything, but looked at the experiment logs written by the scorpion with interest.

It explains the production process of human puppets, as well as the most critical soul storage technology.

Unexpectedly, although the laboratory was disorganized, the scorpion's handwritten notes were unusually neat, and there were even some characteristics of Nara's scientific experiments in his previous life.

Nara took a look at the ten lines and read it with great oblivion, and began to look inside the mine again.

Suddenly, his eyes lit up, and he walked to a storage cabinet,

Open the cupboard, in which the stone with a strange light lies quietly,

"That's it!"

Nara picked up one of them, which was not too big or small, and looked at it carefully.

Although these stones seem to be no different from ordinary stones, but in Nara's perception, it is these stones that do not look amazing.

It contains a lot of natural energy and chakra energy,

"The ore that is said to be the one that can build an ultra-ancient civilization...."

"Grell ore!"

Nara saw the name in the scorpion's experimental notes, and only then did he remember this thing,

What also shines in the plot contains terrifying chakra energy,

"No wonder it can carry souls..."

"With the nature of carrying a large amount of natural energy, it is not impossible to carry the soul naturally..."

Obviously, the human puppet chakra nucleus made by the scorpion is made of Greer ore.

Not only does it carry part of the soul of the puppet as the introduction of the bloodstain limit, but it is also the main power source of the puppet.

The chakra required by the human puppet to launch the spell is basically provided by Grell ore.

"So, in the future, the scorpion will transform itself into a puppet, and it will also use Grell ore as raw material?"

Nara is somewhat clear,

Sure enough, the path to immortality by taking a shortcut has flaws that can't be avoided after all, just like the increase in the entropy of Orochimaru's soul and the scorpion's dependence on Greer's ore,

In this way, the soul is stored in the Grell ore, and once there is no enough Grell ore to replenish the chakra,

The so-called human puppet is nothing more than an inactive dead thing.

"And obviously, the ancient Grell civilization flourished and died suddenly..."

"Nature is related to the misuse of the Greer ore and the depletion of the Greer ore...."

"Now the production of the Greer vein is clearly stretched..."

Nara shook his head, the current output of the Greer vein may be okay for personal use, if you still want to establish civilization or expand production,

That's undoubtedly a fool's dream,

"It's no wonder that in the future, there will always be only one or two scorpion puppets..."

"So the root cause is here..."

"But even if it's used by a limited number of puppets.... The ore will still run out..."

"After all, it's not a long-term solution..."

Thinking about it, Nara took out a sealing scroll and swept away the useful things in the scorpion laboratory,

How can Nara not bring the necessary space equipment for home travel?

It's a pity that if you want to have more storage space, the scroll itself will be larger.

According to the amount of one person carrying, the things that a medium-sized seal scroll can store are still relatively limited.

Just stuffing the notes and the Grell ore into it, it's already full,

"Huh?!"
