Returning to the Land of Demons from the Throne Country, Shiraishi got the information sent by Kakashi from Konoha and Kakashi.

As mentioned above, a meteorite fell from the sky and fell from the sky in the Great Forest of the Fire Country, not far from Konoha, and members of the Akatsuki organization appeared next to the crater with unknown intentions.

In the office, with this information in hand, Shiraishi pondered for a while, and knew that the other half of the polar particles had been obtained by Nagato and Orochimaru.

While they were still figuring out where the polar particles were in the air, Orochimaru was moving significantly faster, and with the power of the Reincarnation Eye, it was not surprising that they could take away the polar particles one step ahead of them.

Although Shiraishi regretted this, when he thought of this trip to the Lietuo Kingdom and obtained the research materials of the reincarnation technique, the harvest was also not small, and this regret quickly disappeared.

What's more, the Oni Country also has half of the polar particles in their hands, and even if they don't get all of them, it will be enough for them to study.

After dealing with Kakashi's information, Shiraishi immediately left the office and walked towards the area of the institute.

When she arrived at her lab, Lynn appeared alone in a white lab coat, and she was holding a beaker to test a beaker in which silver-white grains of sand were stored, glittering.

Lynn's task was to parse the silver grains of sand in the beaker.

Space meteorite material called polar particles.

As soon as he entered, Shiraishi asked, "How is it, how is the analysis of polar particles?" Figured out what this substance does? ”

Lin raised her head and saw Shiraishi coming in, so she nodded and replied, "It's generally clear that this polar particle has a very powerful amplification effect on chakra. And the magnitude of the increase is terrifying. ”

Speaking of this, Lynn's expression became solemn.

"What about the exact numbers?"

"It can allow an ordinary person who is not a ninja to obtain a chakra comparable to a tailed beast in a short period of time."

Lynn made a very intuitive analogy.

Even Shiraishi, after hearing this, was frightened by the chakra amplification effect of the polar particles.

"But the sudden increase in chakras is not a good thing."

Shiraishi's heart quickly regained its calm.

His chakra was also comparable to a tailed beast, but that was because of the dragon vein spar, which became his external organ for storing chakra.

But if the chakra, which is comparable to the weight of a tailed beast, appears directly in his body, then there is only one result, the chakra pipe inside the body will explode, and he will become a waste person from now on.

Why the four generations of Thunder Shadow can have a chakra comparable to a tailed beast, there is nothing yet. Because the other party is the same as him and his father's three generations of Lei Ying, in terms of physique, he is already at the inhuman level.

Therefore, their physical fitness is enough to grasp the chakra of the Tailed Beast level, and they will not be injured by the explosion of the chakra pipeline in their bodies because of the excessively strong chakra.

In this regard, even Ruri and Ayane, who have been strengthened by drugs, are slightly inferior.

On the contrary, if a person's chakra suddenly increases explosively, although they can gain stronger strength in a short period of time, the sequelae after using it will cause endless harm.

Among them, the most typical forbidden technique is the Eight Gates Dunjia.

After the eight doors are opened, it can make Chakra break through the limit of the body dozens of times in a short period of time. Therefore, even a ninja like Maite Dai who is weaker than the average shinobi can fight with Ruri in a short period of time after the eight doors are opened.

However, the result of the use of this kind of physical forbidden technique is that the body suffers sin, and the practitioner will be crippled if he does not die.

Can only be used once in a lifetime.

It's like a brilliant firework in an instant.

When it blooms, it will disappear with the wind.

Therefore, there are pros and cons to the chakra increase.

However, there is no doubt that it can enable ordinary people to obtain chakras comparable to tailed beasts in a short period of time, and the powerful amplification effect of extreme particles is also obvious.

"Yes, the explosive increase in chakra is not a good thing in the long run. However, what I am more curious about is that the Six Dao Immortals had some strange disease that they needed this substance to treat. According to my analysis, polar particles do not seem to have the effect of treating the body. ”

"Why, doesn't Nanao know about this time?"

Shiraishi asked strangely.

In his opinion, the nine-tailed beasts were created for the Six Dao Immortals, and they should know more clearly about the affairs of the Six Dao Immortals.

"No, when the Six Dao Immortals decomposed the Ten Tails and created the Tailed Beast, it seems that they were already in their old age. Chongming only remembered that the Six Dao Immortals had been to the Lietuo Kingdom, but it didn't know exactly what they were going to do. ”

It's not that Lin doesn't want to get the deeds of the Six Dao Immortals and the Lietuo Kingdom from the Seven Tails Shigeaki, but that history is too long, and the Lietuo Kingdom is an extremely closed small country, and it is not a simple matter to restore that history.

"I don't know, I don't think it's a big deal, anyway, it has nothing to do with us. Then again, the polar particles have the effect of amplifying chakra, which has exceeded the limit of what the human body can bear, and it is definitely unrealistic to use it directly for ninjas. ”

Because the amplification chakra ability of the polar particles is too powerful, it is a poison for most ninjas.

Once the chakra explosion in the body exceeds the limit of the human body, the physical trauma caused by it is permanent, and it may even be used once, and you can no longer be a ninja.

"In that case, let's apply it to Mr. Shiraishi's clones, anyway, even if the bodies of those clones are damaged, they can be recreated. The difficulty in the recreation of the doppelganger is the step of reassembling the soul fragments. Fire spirits are very suitable for using this polar particle. ”

Lynn suggested.

The Fire Elves are the clones of fire who shine in the War of the Wind Country.

Usually in the form of a red jade, it is lodged on a steel mecha developed by the military of the Oni Country.

The main body is the same as the Sky Feather Girl.,It has the ability to fly.。

The immortal form is a shockwave that forms a huge scale.

The power of the technique is determined by how much chakra is consumed.

The more chakras consumed, the greater the range of the blast wave that explodes, and the power will increase.

If the next time the fire elf uses the immortal magic to explode, it uses extreme particles to amplify its own chakra, then the fire elf's immortal magic can be called a powerful killer weapon.

"This is a good proposal, with this polar particle, how many times can you fill the tailed beast-level chakra?"

"This half of the polar particles can be about twice."

The complete polar particle is a chakra that can fill the four-tailed beast order.

No, the Six Dao Immortals had also used polar particles, in other words, the chakras of the Tailed Beast that a truly complete Polar Particle could fill were far more than four times.

It's a pity that the probability of a meteorite landing on the earth is too small.

And not all meteorites that fall to the ground will carry such polar particles.

It is obviously unrealistic to make use of the sustainable development of polar particles.

Perhaps only in the future era can human technology reach the level of space, and then this new energy source can continue to be used.

For now, though, human technology is not yet able to go to space.

The industrial technology of the Oni no Kuni is already considered to be at the forefront of the ninja world, but if you want to go to space, even if you focus all your energy on aviation technology, it will take twenty or thirty years of development time to say the least.

It's a pity that in order to prepare for the future upheaval in the ninja world, it is impossible to focus all of its energy on aviation technology.

"Two fills were enough, I thought I could only fill them once. In this case, it is necessary to use polar particles against extremely critical enemies. ”

Shiraishi said.

"In addition to the leader of Yuyin, is there anyone in this ninja world who is worthy of Shiraishi-sensei's serious treatment?"

Lynn was curious.

"The lion fights the rabbit with all his strength, and the ninja's techniques are wonderful, many of which can ignore the gap in hard power to kill the enemy. Human flesh and blood are often inconvenient, so I reserved the resurrection technique in the body of the child. ”

"That's not fair to the child. No wonder he's always been suicidal. ”

Lynn sighed.

Although it is the product of Shiraishi made out of soul fragments, those clones also have their own emotions and are also a living life. When they are separated from the white stone's body, they have their own personality.

Seeing Akako as her second life, in a way, she felt that Shiraishi was also extremely cruel in some way.

"It's not really a death, it's just that the time to reassemble the clone will be a bit long. After all, I also treat them as my own children. He is very aware of his mission and responsibility. As for the suicidal tendencies of the child, it is a little different from what you think. ”

When Bai Shi said this, his face was also a little complicated.

Lynn nodded.

As long as the main body of Shiraishi does not die, then the clone can be resurrected again.

However, Shiraishi said this, it is obvious that the resurrection technique of the red son is not as simple as it sounds, and I am afraid that this resurrection technique has a more special meaning.

"Then again, apart from the rain hidden leader with the eye of reincarnation, and the fire spirit with extreme particles, who else do you have to deal with?"

Lynn asked curiously.

Shiraishi did not answer this question directly, but said in a vague tone: "Let's talk about this matter then, maybe the polar particles will never have a chance to appear." Mass killing is not what I want. It is precisely because the fire elves' immortal skills are so strong that before each use, I will carefully think about whether it is necessary to use the fire elves' immortal arts. ”

Although the fire elf's immortal function is very simple, because of this, it is the most amazing one among all the clones.

As long as enough chakra is supplemented, this kind of immortal art can continue to become stronger, and even the tailed beast's tailed beast jade can surpass it.

With that, Shiraishi glanced around the laboratory and continued, "Regarding polar particles, you can continue to study, which can be regarded as a personal project for you. Next, I'm going to develop new techniques. ”

The new technique naturally refers to the reincarnation technique materials brought back from the Lietuo Kingdom.

The effect of this technique is very powerful, and it can make him and the clone, as well as the tactical system of interaction between Ruri and Ayane, more complete and mature.

"Wait, there's one more thing I want to tell you."

As Shiraishi lifted his feet to leave, Lin suddenly stopped Shiraishi.

"What's the matter?"

Shiraishi turned around and looked at Lin suspiciously.

Is there anything else to say besides polar particles?

"Before that, I would like to ask a question, will the chakra owned by a person produce two kinds of 'traces'?"

Lynn asked earnestly.

After a moment's thought, Shiraishi understood the potential significance of Lynn's question.

Then he shook his head and said: "Under normal circumstances, a person's chakra will only imprint the traces of his own will. The reason why my doppelgangers are different from my chakra aura is that they have become new individuals, essentially belonging to the new human race. How, what do you ask this question for? ”

Chakra's breath is a mysterious and mysterious concept, but for perceptual ninjas, it is easy to judge the identity of the perceived person through the feeling of chakra.

It's because everyone's chakra produces different breaths.

People with dark thoughts, chakras will give people a cold darkness.

For those who have a bright mind, chakra will give people a warm feeling.

Lin was silent for a moment, and then said, "I can't tell you the details, so let's let Mr. Shiraishi verify it yourself." ”

With that, Lynn walked towards the secret door of the laboratory and opened it with the key.

Shiraishi followed and walked in.

The temperature in this dark room is on the low side, and there are experimental equipment in the room, and in the center of the dark room, there is a coffin-style transparent freezer.

The freezer contains the corpse of a powerful enemy.

- Madara Uchiha.

Rin walked to the side of the freezer, looked at the corpse of Madara Uchiha who was frozen in the freezer, keeping his body alive, and said: "Speaking of which, Mr. Shiraishi may not believe it, just two days ago, when I studied Madara's corpse again, I found an extremely faint trace of chakra inside his body. As far as I can tell, it's not Madara's own chakra breath, it's someone else's. ”

After listening to Rin's words, Shiraishi also walked over, looking at Madara's corpse, and the expression on his face became very weird.

"You mean, Madara...... Have two chakra breaths? ”

"Well, it's just that the second chakra aura is very hidden, if it weren't for my cultivation of the spiritual transformation technique that you have improved, maybe I wouldn't have noticed."

Sometimes, in order to understand the secrets in the ninja's corpse, Rin will also use the technique of spiritualization, possessing his soul on the ninja's corpse, so as to better analyze the various secrets in the corpse.

The Spiritualization Technique, which has been improved by Shiraishi, is even more powerful than the original Spiritualization Technique.

Lin also relied on this forbidden technique to discover the strangeness in Madara's corpse.

How can one person's chakra produce two breaths?

"Mr. Shiraishi, did you say that Madara, was he reincarnated as a sacrifice from the beginning?"

Aside from this, Lynn couldn't think of a second possibility.

"No, it won't be reincarnation."

As a traverser, Shiraishi knows very well that his chakra has only one breath.

Strictly speaking, he just carried the memories of another world and descended to the ninja world, but in essence, when a new life is formed in the mother's body, there is only one personality.

If it is a true reincarnation, the chakra will only evolve into a breath.

Even if there are two souls, they will instinctively devour them, forming an independent personality, and the chakra's breath will be unified.

But if, as Lin said, the chakra in Madara has two breaths, it means that the second 'Madara' will die.

At least, he wasn't dead until Madara died, secretly watching in Madara's body.

"What could be the reason for that?"

"Chakra is born with the will of the master, this person can descend his chakra will into Madara's body, and also retain the generation of Madara's own personality, which means that the will of the second 'Madara' does not mean to kill Madara, but just wants to achieve something with Madara."

Spot...... Reincarnation Eye ...... Unlimited monthly reading ......

Dating back to ancient times, the Six Dao Immortals also had reincarnation eyes.

Could it be ...... Shiraishi suddenly felt a pain in his head.

"But if you do that, it will affect Madara's will."

"It's definitely going to be affected, because Chakra ...... It is itself the embodiment of the will. However, this kind of influence is subtle, and it is estimated that even Madara himself will not be able to detect it. Moreover, the second 'Madara' is obviously a character that is even older than Madara. ”

It's a six-way immortal...... Or who?

No, it won't be the Six Dao Immortals.

If it is the chakra will of the Six Paths Immortals, the immortals who have ended the Infinite Moon Reading of the Otsuki Kaguya, Madara will not have the peaceful idea of using the Infinite Moon Reading to envelop humans into the environment.

"The second 'Madara' may not be dead yet, and is still alive in the ninja world."

Shiraishi was silent for a moment before making such a judgment.

"This ......"

"Nothing is impossible. The wisdom of the ancients in terms of technique was not necessarily weaker than ours. Moreover, many ancient forbidden techniques have died out in wars that have lasted for thousands of years...... However, using Chakra to immortalize his will is not only a good idea, but the strength of the sorcerer itself is probably even stronger than Madara in his heyday. ”

Shiraishi has always explored the true meaning of chakra, not the technique that came from chakra.

The reason why his doppelganger has an independent personality and will is because Chakra can inherit the will, and can use it as a blueprint to carry the birth of a new personality and will.

From this point of view, he is not the only smart person in the ninja world.

In ancient times, there were already ninjas who tried to explore the true meaning of chakra, and on the road of exploring chakra, they went further than the current ninjas.

Moreover, he actually used Chakra to achieve immortality in will.

Although Shiraishi himself has hypothesized this possibility, it is not so simple to use Chakra to immortalize his will.

"So what's next? Maybe it's an unexpectedly strong enemy. ”

Lynn thought it was possible.

Shiraishi shook his head and said, "No, being strong is a matter of the sorcerer's life." I believe that if there is a real chance of eternal life, the practitioner will not want to be resurrected. Chakra immortality may be very limited, and it is impossible to completely replace the personality. Otherwise, when he fought with the first Hokage, I am afraid that the defeat would not be Madara. ”

Chakra immortality, this is undoubtedly a very powerful forbidden art.

But precisely because it is a forbidden technique, it is a double-edged sword.

Just like the art of spiritualization, although the soul is infinitely useful, if it fails, the soul will be counterattacked, and it will be seriously injured at least and killed on the spot.

Therefore, Shiraishi believes that there must be some kind of restriction on Chakra's immortality, and it is impossible for the practitioner to really replace the host.

There are troubles, but they are by no means as big as they seem.

After all, he is also exploring the true meaning of Chakra, although he can't achieve Chakra immortality, but with his current ability, he is enough to spy on that kind of realm. Something, he can still see.

Moreover, it is very difficult to find the chakra will that the surgeon has transferred, and it is undoubtedly a needle in a haystack. He didn't have the energy to do it.

Rather than wasting energy on this kind of thing, it is better to find a way to continue to strengthen yourself.

◎

Yuyin Village, the central tower.

"This is the other half of the polar particles left by the Six Dao Immortals, and I will leave it to you to analyze, Mr. Orochimaru."

Nagato placed the bamboo tube with the charm in his hand in Orochimaru's hand.

Orochimaru licked his tongue, his face showed an extremely excited color, and solemnly took the bamboo tube.

"Don't worry, just give me a little time, and I can parse the functionality of this substance. In addition, the matter of dinosaur fossils is also about to be a little frowned, and when the time comes, the strength of the organization will definitely be greatly enhanced. ”

"I hope so. Now that the matter of the Land of Rain has been dealt with, it is time to start the plan to capture the Tailed Beast. ”

Nagato meant something.

He has no worries for the time being, and the next center of his work will be transferred from Yuyin Village to the Xiao Organization.

In particular, the capture plan of the tailed beast is a top priority.

"Now in the hands of the organization, the five-tailed beast has been captured, and there are still eight left that have not returned to their positions. If you want to successfully capture all the remaining eight-tailed beasts, you must recruit new members. Otherwise, with the current dawn, there is no way to snatch teeth from the five major countries. ”

Orochimaru is well aware of the strength of the core members.

But compared to the power of the five powers, Xiao's power is actually very weak.

In every big country ninja village, in addition to the shadow of the ninja village, there are also a large number of high-level ninjas, and they are the real core force of the ninja village.

Orochimaru, who once commanded the Konoha Ninja Village and participated in two ninja wars, knows the heritage of Konoha better than Nagato.

Even though Konoha is now in decline, the core has not been damaged.

As long as it continues to develop, it is only a matter of time before a three-ninja level ninja appears again.

Background is the real key to the decisive gap between the big country ninja village and the small country ninja village.

Just as Nagato was about to say something, a white object suddenly protruded from the floor, and it was Shiraku.

He seemed to hear the conversation between Nagato and Orochimaru, and he grinned and said, "Speaking of new members, I recently found a very nice guy who can be absorbed into the organization." ”

"Who is it?"

Nagato asked.

"A little imp named Deidara, although a little younger than Itachi, was once the ace of the Iwakure Demolition Force, and he was also a disciple of the three generations of Tsuchikage. Strength and potential are guaranteed, and his ninjutsu is also very suitable for dealing with bulky tailed beasts. ”

Bai Jue told the news of the investigation.

"Deidara? I've heard of it, and it seems like a trickster who likes explosives. ”

Orochimaru's voice was hoarse.

"That's right, it's him. He loves the art of exploding. ”

Bai Jue smiled.

"I like art, it's very similar to a scorpion. In that case, let's let the scorpion go. Let Itachi and Oni Shark assist the Scorpion and recruit Deidara. ”

Nagato said.

"Art combination? Sounds great. Speaking of which, it was me who originally teamed up with the scorpion. However, the scorpion is an impatient person, and I hope he doesn't accidentally kill the newcomer. ”

As a teammate in the same group as Scorpion in the past, Orochimaru was well aware of Scorpion's impatience and said it according to his own judgment.

"I'll let the scorpion pay attention to this."

Considering the personality of the scorpion, maybe he will be in a hurry and will really accidentally kill the target newcomer. Nagato had no choice but to say helplessly.

"Then I'll leave first, and then I'll go to Beryuhu. At that time, the resurrected dinosaur is likely to use his ghost bud Luo technique to synthesize and strengthen the dinosaur. ”

With a grim smile, Orochimaru turned to leave.
