Yichen is not in a hurry, slowly emptying his mind, and carefully experiencing the changes around him through perceiving ninjutsu.

Onoki noticed that Yichen was performing perceptual ninjutsu, but he didn't care, he just glanced at Yichen in surprise, it seems that this kid's mental power has grown rapidly in recent years.

After another while, as the natural energy in the sealing area began to increase, Yichen slowly sensed something different. Yichen had already sensed many people's chakras before, but the natural energy had never been officially perceived. This time, under the targeted perception, there is finally some change.

In Yichen's perception, in the sealing area in front of him, something calming was converging. This feeling is different from all the other attributes of Chuck, although it is still very thin, Yichen still vaguely senses the power in it.

This kind of strength is not the strength of the power, but the strength of the rank.

Chakra is graded, when the same ninja first practiced the chakra, the level of the chakra was very low, and the ninjutsu power of the same amount of chakra was also very average, but after exercise, the ninja's will was improved, the physical fitness increased, the extracted chakra was more condensed, and the ninjutsu power cast would become stronger.

The chakra of the upper ninja gave Yichen a feeling that the chakra was stronger than his own. And that year, Shui Wuyue Mirror was able to discover his prying eyes, also because his chakra level was higher than Yichen.

But now the natural energy in the sealing area, although it is very thin, Yichen can feel that his level is very high, so high that it far exceeds the feeling that the Ice Escape and other blood inheritance limits and the upper ninja chakra bring to him.

It seems that it is stronger than the chakra of Onoki not far away.

Onoki also felt the horror of natural energy, but with his level, he could feel more clearly that this natural energy could be harnessed, and with Onoki's chakra amount and chakra strength, if a small amount of natural energy was absorbed, it should be able to be suppressed.

But light suppression is useless, it must be fused, if you can fuse the natural energy with your own chakra, then it is similar to the toad immortal like Jiraiya in the later period.

Thinking of the toad immortal, Yichen's heart moved, and he had an idea, but now is not the time to think about this, Yichen put it aside first.

The most important thing now is to appreciate this natural energy. Through perceiving ninjutsu, Yichen has a refreshing feeling of being in the arms of nature. It was as if his body and mind had been purified, and a smile appeared on his face unconsciously.

After a while, the concentration of natural energy was already very high, and after Yichen felt it again, he opened his eyes, and now he didn't have to experience it with all his heart, even if he was distracted from other places, he could feel it through perceiving ninjutsu.

Yichen looked at the dozen or so ninjas who were still maintaining the sealing technique, and looked at their appearance, he was not uncomfortable, and he was also relieved, it seemed that this step was successful.

Now it's up to us to see if we can maintain this seal.

It's best to do three things at the same time: first, to be able to control the speed at which natural energy is collected, and it would be better if you could stop it comfortably after reaching a certain concentration. Secondly, it is possible to change the caster at any time while maintaining the seal, so that when the caster chakra is not enough, other ninjas can be replaced. Finally, the ability to use natural energy.

Of these three points, the last point is the purpose, but it is not the most urgent, you can take your time, and the first two points are the key.

Onoki also understood this, so after seeing that he had successfully gathered natural energy, he said to the dozen ninjas who maintained the sealing technique: "Okay, the first step has been successful, now try to see if you can slow down the collection speed." ”

When a dozen sealers heard this, they tried to reduce the output of the chakra, trying to keep the sealing technique running while slowing it down as much as possible.

Sure enough, Yichen immediately felt that the speed of natural energy gathering had slowed down. "It works!" Yichen immediately exclaimed.

Onoki also nodded happily, it is good if it has an effect, which means that the natural energy is also controlled by the sealing technique, then there is hope for everything.

In fact, if we can do this step, we have already achieved the expectations of three years ago, even if there is no progress after that, the village can gather such natural energy every time, and then do some experiments before it gets out of control, and slowly, there will be results. Isn't the power of a village comparable to the strength of Orochimaru alone?

Next, Onoki personally commanded the enchantment class and conducted various experiments on this seal, and after a few days, he finally achieved full control of the sealing technique.

After a few minor adjustments, the enchantment class was able to control the start and stop of this sealing technique, as well as the replacement of ninjas. Being able to achieve it so quickly is also the result of the accumulation of the enchantment class, and the enchantment class can be said to be about to be driven crazy by these two fragments in the past two years. Now we can have this kind of harvest, which is inseparable from everyone's efforts.

On this day, Onoki was on the edge of this sealing technique, gathering the top of the village and the heads of the main departments. Because Yichen is an advocate of sealing, he is also allowed to participate in this special meeting.

The content of the meeting is how to use the natural energy that has been gathered, but this aspect is completely blind to everyone's knowledge, and everyone can't say what is feasible.

However, Yichen, an observer, made a suggestion: "Before there are ninjas in the village who can control natural energy, we can treat this area as a special area with excellent environment, and we can try to let ninjas, children, and even ninja beasts live in this area, and see if it can have any impact under the subtle influence." ”

"The creatures of the three holy places are all immortals, and it is very likely that it is caused by living in an environment full of natural energy for a long time."

When everyone heard this, their eyes lit up, yes, maybe the village could artificially cultivate a holy place, and everyone thought about it.

At this time, the squad leader in charge of the medical team said: "We can also get a seal like this in the hospital, so that the environment in the hospital is better, and the wounded may recover faster." ”

After the train of thought was opened, everyone put forward various suggestions in a gossiping manner.

In the end, Onoki clapped the board and first selected a group of ninjas and ninja beasts to enter the sealing area to live. The child will not arrange it for the first time, and wait until it is confirmed that there is no harm before coming to the test. The affairs of the hospital can be put aside first, and a special area can be set up first, and the patients who are recuperating can be arranged to live in it first.

In this way, the village began to select some talented young ninjas and some ninja beasts that were of great help to the war, and let everyone move to live within the scope of sealing arts.

Yichen volunteered to be the first to move in. Everyone has no opinion, with Yichen's contribution, everyone doesn't care about this little thing. Anyway, with Yichen's talent, he was selected, and he was not far from ten.

Yichen has been looking forward to immortal arts for a day or two, since three years ago, the matter of natural energy has almost become his obsession.

In the next ten days, Yichen almost never left the sealing area, and the talented ninjas selected by the village had not moved in, and Yichen had always lived in it alone. Yichen estimated that the village also wanted to see his reaction before making up his mind.

In the past ten days, Yichen has not experienced any discomfort, and he has been using perceptual ninjutsu to sense natural energy every day. Yichen had a feeling that he didn't know enough about natural energy, and his intimacy was not enough, so it was difficult for him to cultivate immortal arts.

In other words, he didn't have enough talent to practice immortal arts. But these days, living within the scope of the seal, slowly using perceptual ninjutsu to probe, Yichen has a feeling that his affinity with natural energy seems to be improving. There is no basis for this feeling, and it may even be psychological, but Yichen still hopes that it is true.

After reporting his feelings to Onoki, Onoki directly brought several consultants over to inquire about Yichen's specific situation. One of the advisors even asked Yichen if he had any advice on what kind of ninja to pick to enter the sealing area.

This question opened Yichen's mind, although he was not familiar with natural energy, but the examples of understanding heaven and earth in the online novels in his previous life were not less, so Yichen said his guess: "Lord Tsuchikage, several advisors, I think the candidates we choose can focus on those ninjas who are more plain-minded and love the flowers and plants in the natural world." ”

Several advisors glanced at each other, but they didn't expect Yichen to say such a solution, and it made sense to think about it, but another advisor said: "There are a lot of ninjas in the village who kill people very much, but they are plain-minded, I'm afraid it's not easy to find." ”

When Yichen heard this, another thought flashed through his mind: "Lord Advisor, maybe you can also find some people who are particularly murderous, and things must be reversed, these people who are incompatible with nature may be more able to perceive natural energy." ”

Onoki and several advisors looked at each other, a little incomprehensible, but it was not a difficult task, and Onoki directly arranged for a consultant to do it.

In the end, Onoki asked Yichen if there were any side effects of living in the sealed area. After knowing Yichen's reply, Onoki directly ordered that the selected people move in tomorrow.

Feeling natural energy is not an overnight thing, a while ago it was because he acted as a guinea pig, so the village did not arrange a task for himself, and now the work of the guinea pig is over, and the village's arrangement has also come down. The fifth class was disbanded due to the promotion of all three members of the team to the middle ninja.

Tian Nai and Yichen were placed in the dark department, but Shinohara, who was arranged with three team members to form a new class. In fact, the village's consideration is very reasonable, Shinohara has grown up for two years, and his physical skills are already very good, and he is completely suitable for the position of captain, and he has finally learned the first C-level ninjutsu in ninjutsu.

And Tian Nai, although his strength is good, his shortcomings are too obvious, and he has more than enough personal self-preservation, but it is difficult to protect the team members.

As for Yichen, the village hopes that he can train through the shadows again, and then go to the side alone. The village didn't want to let a genius like Yichen out alone early, and still hoped that he would grow up for a while under the care of his seniors.
