Yichen has been in a good mood recently, whether it is the change of Onoki, or the progress of Matsutani Shinya and Katsumata, it is a happy event for Yichen.

And after completely getting rid of the Lei Dun research and development task, Yichen now basically has no other official duties except for taking apprentices.

This year's intermittent research and development and cultivation of Lei Dun have raised Yichen's thunder attribute proficiency to a new height. It is not much different from the original expectation, and now Yichen's thunder attribute proficiency is no less than that of the water attribute.

It's time to start the development of the second blood inheritance limit, and it's decided, so I choose Lan Dun, who combines water and mines.

But the good mood didn't last long, and the development of the Arashi Blood Inheritance Limit didn't start immediately, because Onoki sent the dark department to inform him of the meeting.

When the ninja world was peaceful, high-level meetings were rarely held, and the last time Onogi Xianjutsu was successfully cultivated, there had just been a meeting, and Yichen couldn't guess what the content of this meeting was. But his intuition told him that the meeting would not be easy.

Sure enough, when Yichen entered the office of the Tsuchikage Building, he immediately saw a trace of excitement in Onoki's eyes.

Instead of sitting at his desk, Onoki floated in the air with the Light and Heavy Rock Technique.

Seeing this scene, Yichen became more and more curious, and threw an inquiring look at Yi Cang, who had arrived one step earlier than him, but Yi Cang shook his head at Yichen in the same confusion.

Soon, the people who participated in the meeting arrived, and as soon as Onoki and the others sat down, they immediately said: "The dark department has discovered the whereabouts of Jiraiya, and he is in the land of Yuno during this time. ”

Yichen was stunned, and he came too? Isn't it?

Sure enough, Onoki continued: "I have already sent someone to pass the news to Yun Ren, I believe that Yun Ren will make a move soon." It's just that we discussed it last time, and there is also a helper from Miaomu Mountain, and it is difficult to be killed. ”

"So this time I'm going to go to the land of Tang in person, and after Yun Ren starts to attract Jiraiya's attention, I will use Dust Escape to sneak attack Jiraiya."

When Yichen heard this, he was shocked, this method is actually good, it is impossible for the toad of Miaomu Mountain to control the situation remotely, and he will go against the spirit as soon as he encounters danger.

If you can use the dust to sneak attack before Jiraiya himself sends a distress signal to Miaomu Mountain, then the possibility of success is not low.

The most important thing is that Yuyun Shinobu acts as a target in front to attract Jiraiya's firepower, and Onoki only secretly attacks, even if it fails, Iwa Ninja Village will not lose anything.

With the courage of the ape to fly and slash the sun, it is not enough to start a ninja war because of a jiraiya.

Yichen analyzed it in his heart, and he was also a little moved. After more than ten years, Yichen is no longer the otaku who has only read the original book, and if he can kill Jiraiya, Yichen will definitely not hesitate at all.

This has nothing to do with whether Jilai is a positive character or not, and Yichen wants to kill Zilai simply because the two sides have different positions. After Orochimaru's defection, Jiraiya is almost the most important combat power in Konoha on the face, and there is no one.

So after listening to Onoki's words, Yichen was the first to speak: "Tsuchikage-sama, I'll go with you." ”

Onoki nodded and said, "Yes, we can fly over together with the Light and Heavy Rock Technique." ”

Ikura, Saka, and Hakura glanced at each other, and although the three of them didn't have much hope for Onoki's trip, they didn't have an opinion.

Because there are not many shadow levels in the ninja world that have the ability to fly, except for Onoki and Yichen, there are only four generations of Wind Shadow Luosha.

If Onoki went alone, everyone might still be a little worried about his safety, but with Yichen, a new shadow level, then they would have nothing to worry about.

Ikura and the others discussed a few more words about the defense of the village during the time that Onoki was gone, and the meeting ended.

The high-level meeting was very efficient, and in less than a minute, the high-level leaders reached a unified opinion.

After the meeting ended, Yichen stayed in Onoki's office, and Onoki needed to explain the village's official business before he could leave.

It's just that while waiting, Yichen suddenly thought of something and said to Onoki: "Tsuchikage-sama, why don't we enter the immortal mode first and use the immortal mode to fight?" ”

Onoki was explaining his work to the three of Loess, and he was stunned when he heard Yichen's words.

Neither Onoki nor Yichen's immortal skills can be used in actual combat, because the two of them need to make a lot of preparations to enter the immortal mode, and it takes a long time.

And the battles carried out by ninjas are often sudden, so Onoki subconsciously did not count the immortal mode in his combat effectiveness.

After thinking about it for a while, Onoki said: "I'll forget it, I just learned immortal arts, and after entering the immortal mode, I can't control the fluctuations of immortal chakra, and it's easy to be exposed." However, you can prepare for the immortal art first, and it just so happens that the perception in the immortal mode will also expand, and entering the immortal mode can also increase your perception. ”

Yichen nodded, and immediately went to prepare for the immortal mode.

Since learning the immortal era, as long as Yichen is in the village, he will enter the immortal mode once a day, and under normal circumstances, he will maintain the immortal mode and do not use the immortal chakra.

So after more than a year, Yichen's body's adaptability to the Immortal Chakra has been greatly improved. Now after Yichen enters the immortal mode, the immortal face is almost only about half of what it was at the beginning.

It's just that Yichen still can't enter the immortal mode outside of the natural energy seal. However, it is still possible to perceive the thin natural energy of the outside world.

In addition, Yichen is also unable to leave the liquid natural energy and directly enter the immortal mode. But now that Yichen is practicing immortal arts, there is no need for Yi Cang to guard it with a black stick.

Yichen quickly came to the natural energy experiment area, which was no longer empty and deserted at the beginning, and the village had already built a closed building here.

The entire building is divided into two parts, one is the experimental area and the other is the natural energy sealing area. The experimental area produces liquid natural energy, and the sealing area absorbs natural energy.

Since Yichen and Onoki had to practice immortal arts once a day, the village built this place into a military base.

Considering that the study of natural energy is a top secret in the village, the defense here is in charge of the Shadow Ministry.

Even if Yichen is a frequent customer, he has to verify his identity if he wants to enter it.

After confronting the code with the guardian darkness, Yichen directly entered the experimental area.

It happened to be Vortex Yumi who was on duty in the experimental area today, and when she saw Yichen coming, Vortex Yumi said hello to Yichen, and took her disciple down the mountain to prepare liquid natural energy for Yichen.

Seeing this, Yichen didn't stay here, and went directly to the natural energy seal next door. After finding a place to sit cross-legged, Yichen began to adjust his state.

Although it is said that with Yichen's current proficiency in immortal arts, even if he is not so serious, it is no problem, but Yichen is still preparing very carefully.

After a while, Yichen felt a chill on the back of his hand, and then a large amount of natural energy quickly surged in from the back of his hand.

Completely different from the hustle and bustle in his early years, Yichen easily controlled the natural energy that entered his body and his own physical energy and spiritual power to complete the fusion.

Basically, as much natural energy is fused until the limit of what the body can bear, Yichen naturally stops absorbing natural energy.

After a while, Yichen slowly opened his eyes, and at this time, some immortal faces had appeared on Yichen's face. However, the coverage of the immortal face is less than half of the first.

Seeing this, Dai Xiashan, who had just given Yichen drops of liquid natural energy on the side, put away the black rod in his hand.

Yichen nodded to her and walked back through the experimental area to the outside, just as Onoki had finished his official business.

Seeing that Yichen had entered the Immortal Mode so quickly, Onoki was not surprised, he was very clear about Yichen's progress in cultivating the Immortal Mode.

Without staying at the door of the experiment for too long, Yichen and Onoki flew into the air together with the light and heavy rock technique and camouflage technique.

Then the two of them flew towards Yunokuni while chatting.

"Let's try the perception range in Immortal Mode." Onoki said to Yichen that this is very important, and it will largely determine where the two of them will hide in the future.

Yichen nodded, although he had already known the blessing effect of the Immortal Chakra, he still closed his eyes and focused all his attention on the S-level illusion of the Heart Eye, and then cast a perceptual ninjutsu in the air.

After half a ring, Yichen said: "The increase of natural energy on the heart eye is very large, and the effective distance that I can reconnoiter with the heart eye under normal conditions is three hundred meters. But in the immortal mode, it is almost 3,000 meters. ”

"But the increase of immortal magic on perceptual ninjutsu is smaller, I can sense more than 500 meters when I use perceptual ninjutsu in the air under normal circumstances, and with the blessing of immortal chakra, it only reaches 2,000 meters."

"However, the effect of perceptual ninjutsu is better on the ground, and the range that I can perceive on the ground under normal conditions is almost 4,000 meters, and if I get the blessing of the Immortal Chakra, it should be able to reach 16,000 meters."

Onoki nodded, he knew very well about the perceptual ninjutsu that Yichen said, and he would, but he didn't master it as well as Yichen.

It's just that he didn't expect the increase of the immortal technique on the S-level ninjutsu of the heart eye to reach ten times. That's ten times the distance, not ten times the intensity. Any ninjutsu must be more difficult the farther away, and the difficulty must increase exponentially as the distance increases.

After thinking about it, Onoki still asked, "Do you know why the increase in immortal magic on the heart eye is so large?" ”

Yichen had also considered this question before, so the answer was very clear: "Although I don't know the principle of the Heart Eye, the reason why my Heart Eye was able to successfully cultivate was because I unintentionally absorbed the natural energy that time. ”

"Moreover, I suspect that the effect cannot be improved after the cultivation of the Heart Eye, and the perception distance has always been about 200 meters after I cultivated the Heart Eye, and it has not increased at all. Even though the mental strength and physical strength have been increasing, the ability of the mind and eye has not changed at all. ”

"But the immortal art should be able to slowly increase the effect of the heart eye. Ever since I cultivated into the Immortal Mode, the perceptual distance of my heart eye has slowly increased. ”

Onoki nodded, he knew about the magic of natural energy, and although he couldn't understand it, he wasn't surprised.

"What's the most powerful immortal technique you can use right now?" After a while, Onoki asked again.
