The next day, Yichen took Matsutani Shinya to meet the giant panda, and Matsutani Shinya's affinity for animals is also useful for this giant panda, but it is obviously not as big as ordinary small animals.

The difference in the panda's attitude towards Matsutani Shinya is that he is not repulsive, but he doesn't think that Matsutani Shin is also very much in line with his preferences.

However, Yichen saw that he had another idea, and he asked Matsutani Shinya to talk to the giant panda to see if the giant panda knew the cultivation method of immortal arts or the absorption method of natural energy.

The giant panda was still quite surprised by Matsutani Shinya's question about immortal arts, and he leaned down and sniffed Matsutani Shinya carefully, but found nothing. Then he looked at Yichen who was standing behind Shinya Matsutani, and leaned over to sniff Yichen again.

This time, the giant panda's expression was a little puzzled, and he asked Yichen: "Little guy, have you absorbed natural energy?" How come you didn't petrify and didn't fuse natural energy? ”

Yichen was stunned for a moment and said: "Senior, I inadvertently absorbed natural energy, and I was almost petrified at that time, and later used the natural energy in my body to practice a ninjutsu, which avoided petrification." ”

The giant panda can't seem to understand how Yichen practiced ninjutsu through natural energy.

Seeing this, Yichen asked again: "Do the seniors know how to absorb natural energy?" ”

The giant panda said: "There is a way to absorb natural energy, but it is very difficult to do, even I only know this method, I have not tried it." ”

"Little one, natural energy is not so easy to absorb, if you can't control natural energy, it will petrify."

After hearing this, Yichen took out the black rod he got from Nagato and asked, "Senior, in Miaomu Mountain, one of the three holy places, it is said that there is a black rod that can disperse the uncontrolled natural energy inhaled into the body, I don't know if it's such a thing." ”

Remember the URL

The giant panda looked at the black stick, shook his head and said, "I don't know about Miaomu Mountain, natural energy is secret, and Miaomu Mountain will not reveal it." ”

Yichen thought for a moment and said, "Since the seniors know the way to absorb natural energy, can you tell us that we also want to try the power of natural energy." ”

The panda thought for a moment and said, "Well, if you use this place in exchange, I agree." ”

"Ugh." Yichen was stunned, he didn't expect the giant panda to make such a request, originally this giant panda was not very willing to contribute to the rock ninja, but because of the natural energy seal, he had to agree to become a psychic beast to fight for the rock ninja.

Although the village has not yet found a suitable psychic ninja, once it is found, it will be a long-term deal. Now this giant panda is going to complete the long-term deal for Iwa Shinobi at once.

Yichen turned his head to look at Onoki, who was also a little entangled, unable to make a decision for a while, and said, "Go back and gather the advisors to discuss." ”

Yichen nodded yes.

Giant psychic beasts and immortal arts, this is a dilemma, if after getting the method of absorbing natural energy, it can ensure the success of cultivating immortal arts, then Ohnoki is still willing to exchange.

For one, immortal magic can greatly increase the combat power of the shadow level, while the increase brought by giant psychic beasts is very limited. Second, immortal arts can be promoted, and many people can learn together. Unlike giant psychic beasts, there is only one, and only one person can be helped, at least only one person can be helped at the same time.

But unfortunately, Yichen is not sure whether he can practice immortal art after receiving the method of absorbing natural energy that the giant panda said.

At the high-level meeting, everyone's opinions were not unanimous, and the Ming was the opponent, not because he didn't think it was cost-effective, but because he felt that it was too dangerous, and the immortal magic was uncontrollable, but the psychic beast was controllable. Although this giant panda has a lot of requirements and refuses to suffer, it can at least communicate, which is very rare.

But there is a danger of petrification in cultivating immortal arts, and those who can be qualified to practice immortal arts are the elites of the village, Iwa Ninja Village is not Konoha, Konoha can afford to lose, but Iwa Ninja Village can't afford to lose.

Especially Yichen, when he looks at Yichen, he is a person who especially wants to learn immortal arts. Yichen is a quasi-shadow, and he is still a consultant of the village, so it is needless to say that he is important to the village, and he doesn't want a genius like Yichen to take such a risk.

Saka was supportive, and his reason was simple: "The giant psychic beast can at most allow ninjas to reach the level of the three ninjas of Konoha, but the last user of the immortal art is a thousand hands pillar." ”

It was this sentence of Saka that directly moved Onoki. Onoki will never forget the shame of being threatened by Madara Uchiha back then. If the senjutsu can reach the level of the first Hokage, then Onoki himself is willing to take this risk.

Instead, Ikura said, "Tsuchikage-sama, could this giant panda be a spy sent by Konoha?" After all, that psychic scroll was also obtained from the Konoha ninja. ”

Yichen was stunned, he didn't expect Yicang's brain circuit to become so strange now. Yichen didn't think about this at all, because he knew that although the immortal art was the ability of the first Hokage, Konoha did not have a related inheritance, and the immortal art has always been a thing of the three holy lands, and it is different from Konoha.

For example, the original Konoha Traitor Ninja Yakushi Dou is an immortal technique learned from the Dragon Land Cave.

In other words, as long as the three holy places approve, no matter what identity that person is, whether it is related to Konoha or not, it is possible to learn immortal arts.

After listening to Ikura's words, Onoki gritted his teeth and said, "I still have to change, it's just that we high-level cultivators can only come one by one, and before the previous one succeeds in mastering the immortal arts, others can't try to practice." ”

"Yes." All should be. Ohnogi didn't say this to Saka and Ming, the strength of the two of them was not enough, and they didn't have the idea of practicing immortal arts.

The high-level people who were qualified to practice immortal arts were originally supposed to be the two shadow levels of Onoki and Ikura, but Yichen's expectations were stronger than the two.

After the results of the high-level meeting, Onoki took Ikura and Yichen to the natural energy seal where the giant panda was.

"We choose to exchange and absorb natural energy." Onoki said to the panda.

The panda accepted the exchange and recounted the methods he knew of absorbing nature's energy.

After listening to the giant panda's story, Onoki and Ikura looked at each other.

Originally, they thought that the panda would teach them a meditation-like method, but the panda said that it would take something external to absorb natural energy.

This foreign object is the rich self-energy, the natural energy that is so rich that it is liquefied.

Onoki and Ikura don't know why, but Yichen thinks of the toad oil of Myoki Mountain. Could it be that toad oil is the natural energy that is so rich that it is liquefied?

Yichen said to Onoki and Ikura who didn't know why, "Why don't you adjust the seal and increase the concentration of natural energy?" ”

Onoki nodded and said, "It's okay to try, but you have to control the range." Don't forget, natural energy is uncontrollable and can be dangerous. ”

Yichen nodded in understanding.

As Yichen's advisor who is good at sealing, this matter naturally fell on his head.

It was not difficult to increase the concentration of natural energy, and with the level of the sealing technique of the Iwa Ninja Village, it was possible to do it a long time ago. Before, I was afraid that natural energy was too dangerous, so I controlled the concentration within a suitable range.

What Yichen has to do now is to find a way to increase the concentration of natural energy through experiments, but not cause a natural energy riot.

Yichen found a relatively secluded place outside the village, and informed the enchantment class to arrange the shield and defense of the enchantment. Then he asked Onoki to arrange the dark department to guard.

Yichen is self-aware, and he knows that this thing will definitely not succeed in a day or two. This research may be another long-term project.

I just hope that it won't be like when I studied the fragments of the Fire Domain Seal, and I often counted it in years. Yichen doesn't have that much time to waste.

The basis of the experiment is still the original natural energy seal, but the link in the original seal that restricts natural energy and does not increase it excessively can be canceled.

In fact, when the natural energy seal was just studied, there was a thing where the natural energy was too strong, and finally the seal collapsed.

The cost of setting up the natural energy seal was not low, and the village did not have the need to study this aspect at that time, so it did not go further into it.

Now Yichen will dominate the experiment in this direction.

It has been many years since he has conducted research on the development of sealing techniques, and Yichen is still quite excited.

First of all, what Yichen has to do is not to test directly, the current seal is too big, and the cost is too high. Even if he hasn't tried it yet, Yichen knows that this research process is not a one-time or two-time success. Although Iwaninja Village has developed well in recent years, it cannot afford such a squander.

Yichen first had to shrink the original huge seal, and the reduction in size would inevitably bring about a decrease in cost.

This is not difficult, Yichen and the Suwon squad leader of the enchantment class and others have simplified it in less than three days of research.

The seal is still the same seal for the most part, but with a lot less repetition to increase the area. So the process went smoothly.

Three days later, Yichen and the others constructed a new natural energy seal in the selected experimental area.

This seal is about the size of a room. Yichen and a few people calculated the cost, and they were barely able to accept it.

The research quickly moved on to the second step, removing the part of the seal that was originally used to maintain balance. This seems simple, but it is actually very troublesome, because the purpose of Yichen is not to completely debalance, but to achieve control over the natural energy in the end.

Therefore, while canceling the original balance setting, a lot of content for bootstrapping should be added.

Due to the fact that the original large seal was reduced by Yichen, this also caused the new seal's ability to withstand natural energy to be weakened a lot, so the process did not go smoothly.

The results of more than a dozen experiments were all shattered by the violent natural energy energy. Fortunately, the seal was relatively small, and there was not much natural energy gathered, so the ninjas who participated in the research were not injured.
