Of these two illusions, the first is the scene simulation illusion developed by Yichen at the beginning. It's just that the illusion developed by Yichen is very limited, and it requires the active cooperation of the recipient. Yichen has only been used once with the cooperation of northern Sichuan.

It was also at that time that Yichen and Chuanbei both comprehended the sword qi.

This time, Konoha handed over the full version of the illusion that could be used in actual combat to Iwa Shinobi. The name of the illusion is Mirror Elephant World, and it is said that there is an advanced version of this ninjutsu in Konoha. Yichen guessed that the advanced version might be related to the Kaleidoscope Writing Wheel Eye Illusion Moon Reading.

Another illusion is the group illusion, which is the Nirvana Essence Technique that the original Chinese Medicine Practitioner Dou used in the Twelve Little Strong's Zhongnin Exams.

In Konoha's opinion, the effect of these two illusions is not great, the mirror image world has very high requirements for the caster, although the number of rock ninjas is large, but only a small number of ninjas can learn.

And in Konoha's opinion, the technique of Nirvana Essence House is completely a chicken rib, after being performed by the elite upper ninja, even the lower ninja can easily crack the illusion technique, what is the use?

But Iwa Shinobi's idea is completely different, Iwa Shinobi put these seemingly useless ninjutsu on the list, and his intention is not to rely on these two ninjutsu to improve Iwa Shinobi's strength at all.

Iwa Shinobu hopes to fill the gap in this field in the village through the study of these ninjutsu.

Both the art of Nirvana and the mirror image of heaven and earth have their own specialties and have high research value.

In addition to these two B-rank illusions, the effects of other B-rank ninjutsu are basically similar, except for a few ninjutsu that can be used in actual combat, most of the ninjutsu are biased towards research rather than combat.

It's just that Konoha is not stupid, and the attributes of the ninjutsu delivered to Iwa Shinobi this time are relatively simple, focusing on wind escape and water escape. As for Lei Dun, there was none. Of course, there are no earth escapes and fire escapes, earth escapes because they are not needed, and Iwa Shinobi is not listed, but fire escapes because they are not necessary.

Fire escape ninjutsu is not like other attributes of ninjutsu, fire escape is somewhat similar to Yichen's porcelain escape, both of which do not need a fixed form, and being able to change at will is the best way to exert the power of fire escape.

Yichen's porcelain ninjutsu has no fixed name and fixed form, and it is often how to come as you want.

Konoha knew that Iwa Shinobi had a lot of wind escape and water escape ninjutsu, so there were not many restrictions in this regard. And the most scarce thunder escape of the rock ninja, this time Konoha is stuck very dead.

Yichen's water escape is well mastered enough, and the B-grade water escape given by Konoha is not of much help to Yichen's water escape. In terms of wind escape, after a month or so of hard work, Yichen has not yet reached the level where he can perform even a C-level ninjutsu. Therefore, in addition to increasing Yichen's knowledge, these Wind Escape Ninjutsu are no longer helpful in a short period of time.

Three A-level ninjutsu are not bad, one wind escape is crushed, Yichen can't learn it, and the remaining two water escapes are Yichen learned very seriously. Because this should be of great help to him in developing and upgrading the Water Escape Ninjutsu.

Recently, there has also been a good thing, Yichen's disciple Kajiyamari has finally completed the development of his first ninjutsu, and amazingly, he has recently completed a breakthrough.

That's right, following Chinoe, Kajiyama also embarked on the road to Kaminin.

Yichen only learned about this when he returned to the camp on the Eastern Front. When I asked the reason, it turned out to be because I saw the rapid growth of Yichen's three newly recruited disciples and felt the pressure. With this sense of urgency, Kajiyamari magically broke through.

Thinking about it carefully, Yichen was relieved, Yichen had six disciples, only Kajiyama was strong when he was in the ninja school, and it was okay when there were only three people in the original team, because the ninjutsu-type ninja did suffer more in the early stage, so Kajiyama was able to accept that Kajiyama was better than him at this stage.

Chiko-megue's breakthrough was an accident, and Kajiyama didn't think much about it, and besides, Chiko-hui's foundation was too poor, and although she broke through, she didn't know how long it would take to become a shinobi.

But Yichen accepted three more disciples, which made Kajiyama feel anxious.

Especially after seeing that the little starling Saki who came out of the ordinary class was also trying to develop ninjutsu, Kajiyama couldn't sit still.

And what really pressed Kajiyama to complete the breakthrough was the insight that Kostarling Saki once described when he asked him for advice on the development of ninjutsu. At that time, it is no exaggeration to say that there was a feeling of a mouth in Kajiyama.

When the person who was consulted listened to the problem of others, he had a feeling of being sudden, and the whole person in Kajiyama became a little dazed.

By the time he came back to his senses, more than an hour had passed, and the little starling Saki who was originally asking him questions had already been taken away by Chiko Hui. As a person who has come over, Chikohui knows that Kajiyama can't be disturbed at this time.

Miraculously, Kajiyama has made a breakthrough, and has made qualitative progress in the development of ninjutsu. And Kajiyama's foundation is far better than Chiko's, although it took so long to break through, but it's not surprising that Kajiyamari should become a shinobi earlier than Chiko-Hui.

Yichen was a little ashamed, he chose Kajiyama but couldn't really help him, and now he wants Starling Saki to order him. I'm a little incompetent as a teacher.

What's even more embarrassing for Yichen is that among the three of Zhizihui, Kajiyamari, and Chuanbei, the only one in Chuanbei who has not yet broken through, has been unable to learn anything from Yichen.

The path taken by northern Sichuan is completely different from Yichen, Yichen can give too little guidance to northern Sichuan, when he just graduated, Yichen's half-hung knife knowledge can still guide him a thing or two, but now in terms of understanding of knife skills, northern Sichuan has surpassed Yichen.

The only thing that comforted Yichen was that he took Chuanbei to the camp on the Eastern Front. At least there is Zidian, a sword master here, who occasionally instructs him.

Now Yichen is hesitating whether to take Zhizihui and the others back to the village.

I want to go back to the village to learn S-level ninjutsu, and the three new disciples will definitely go back with me, but the three old disciples are all middle ninjas, and theoretically the first class no longer exists. They should now go their separate ways.

But Yichen subconsciously felt that the three of them were still young, and it was too early to leave. After all, they really aren't that big in terms of their age.

In the end, Zidian saw Yichen's hesitation and persuaded Yichen.

Yichen disbanded the first class and brought all three of them back to the village, leaving Onoki to arrange the future of the three.

After returning to the village, Yichen went to collect the S-level ninjutsu. Yichen has already read the catalog of S-level ninjutsu, and has also selected the ninjutsu to learn in advance.

Originally, Yichen was going to learn the technique of super-weighted rocks, and this ninjutsu can suppress the tailed beast if it is used well, which was originally Yichen's first choice, after all, Yichen does not have a good way to deal with the tailed beast.

But after being reminded by Yi Cang, Yichen changed his mind, and when choosing ninjutsu, he should consider time and space ninjutsu. Not only to deal with the wave wind and water gate, but also to deal with the Uchiha Obito that may be blackened in the future.

In the end, the ninjutsu chosen by Yichen is perceptual ninjutsu, yes, it is perceptual ninjutsu, but it is different from the perceptual ninjutsu that Yichen learned before, this is listed as an S-level perceptual ninjutsu, which does not need to be sealed, does not need to be deliberately perceived, and does not need to point a finger on the ground.

This S-level ninjutsu can be described as a passive skill in one sentence.

As long as there is a chakra fluctuation, a ninja who knows this S-level ninjutsu will naturally be able to detect it.

The second-generation Tsuchikage in the original book is not able to do this ninjutsu. In the face of Wu, any sneak attack is useless, even if Wu is fully preparing for the S-class ninjutsu Dust Escape Origin Stripping Technique, he can also sense the danger after coming to himself.

Yichen hopes to use this ninjutsu to determine whether the future Obito is in a state of voiding.

Iwa Shinobi's collection does not contain space-time ninjutsu, and Yichen can't get a way to truly restrain time-space ninjutsu. Yichen can only think of judging the opponent's state through S-level perceptual ninjutsu.

To be honest, Yichen wasn't sure if this ninjutsu would be useful to Obito, but Yichen wanted to try it.

It's still early before the fourth battle, and Yichen feels that there will be a chance to learn powerful attack ninjutsu in the future, and it's really good to learn this perceptual ninjutsu first.

Onoki frowned when he saw Yichen's choice, and then he thought of the method that Ikura said that day against Bo Feng Shuimen.

Onoki shook his head and said, "The power of the Flying Thunder God is that it is fast, even if you can sense the position of the opponent, you won't have time to deal with it, so you don't need to learn the Perception Ninjutsu specifically in order to deal with the Flying Thunder God." ”

"This ninjutsu my teacher second-generation Tsuchikage has also learned, and he has fought with the second-generation Hokage who has the Flying Thunder God, and this ninjutsu is not of much help to him."

"Eh~" Yichen didn't expect this stubble, yes, Wu and Qianshou are both second generations, and it is normal to have a fight.

After thinking about it, Yichen still said: "I still want to learn this ninjutsu, I want to see if it works." ”

Onoki thought for a while and said, "Try it, try it, whether you can learn it or not, come and learn a new one when the time comes, this ninjutsu is too little of help in battle." ”

Yichen's eyes lit up, and there is still this benefit? Hurriedly nodded desperately.

The reason why Onoki is so generous is because he feels that Yichen is making a sacrifice by choosing this ninjutsu, a sacrifice for the sake of the village.

Second, because Yichen's foundation is far inferior to Yicang, the time required for Yichen's real transformation to complete will be far greater than that of Yicang. Yichen should have time to learn two S-rank ninjutsu.

"This ninjutsu is not easy to learn, and it is said that it is very accidental that the second generation of adults can master it. If you don't feel like you can learn it, don't bother with it, don't waste too much time, and learn a new ninjutsu as soon as possible. ”

Yichen nodded, no matter what Onoki said, he wouldn't change his mind.

Onoki opened the seal scroll to its position and unlocked the seal. After confirming that Yichen had completely memorized this ninja, he resealed it. Then he applied a secret sealing technique in Yichen's mind, and then left the secret room with Yichen.
