The Second S-rank Ninjutsu

Of these two Genjutsu, the first was the scene simulation Genjutsu that Yichen had developed. However, the Genjutsu developed by Yichen were very limited in their use, as they required the active cooperation of the target. Yichen had only used them once with the cooperation of Kawakita.

It was on that occasion that Yichen and Kawakita both comprehended the Sword Qi.

This time, Konoha handed over the complete, combat-ready Genjutsu to the Iwa ninja. The Genjutsu is called Mirror World, and it is said that there is an advanced version of this Ninjutsu within Konoha. Yichen speculated that the advanced version might be related to the Mangekyō Sharingan Genjutsu Tsukuyomi.

Another type of Genjutsu is a group Genjutsu, which is the Nirvana Abode Technique Kabuto Yakushi used during the Chunin Ninja Exams of the Konoha 11 in the original work.

From Konoha's perspective, neither of these Genjutsu was very effective. Mirror World required a very high level of skill from the user, and although there were many Iwa ninja, only a small portion of them could learn it.

In Konoha's eyes, the Nirvana Abode Technique was utterly useless. What use was Genjutsu that even Genin could easily break after being cast by Elite Jonin?

However, the Iwa ninja had a completely different idea. They included these seemingly useless Ninjutsu on the list, not because they hoped to improve Iwa ninja strength with just one or two Ninjutsu.

The Iwa ninja hoped to fill the village's gaps in this area by studying these Ninjutsu.

Both the Nirvana Abode Technique and the Mirror World have their own strengths and are of great research value.

Aside from these two B-rank Genjutsu, the other B-rank Ninjutsu have similar effects. Apart from a few Ninjutsu that can be used in actual combat, most Ninjutsu are more geared towards research than combat.

However, Konoha wasn't stupid. The Ninjutsu they delivered to the Iwa ninja this time were all relatively simple in nature, focusing on Wind Release and Water Release. As for Lightning Release, there wasn't a single one. Of course, there was also no Earth Release or Fire Release. Earth Release was because it wasn't needed, and the Iwa ninja didn't include it. Fire Release was also because it wasn't necessary.

Unlike other elemental Ninjutsu, Fire Style Ninjutsu Fire Release is somewhat similar to Yichen's Porcelain Release. Neither of them requires a fixed form; the best way to unleash the power of Fire Release is to be able to change it at will.

Yichen's Porcelain Release Ninjutsu has no fixed name or form; he can use it however he wants.

Konoha knew that Iwa ninja possessed a considerable number of Wind Release and Water Release Ninjutsu, so there weren't many restrictions in that area. However, Konoha was very strict about limiting Iwa ninja's Lightning Release, which was extremely scarce.

Yichen's mastery of Water Release was already quite good; the B-rank Water Style Jutsu given to him by Konoha wouldn't be of much help in developing Yichen Water Release. As for Wind Release, after about a month of effort, Yichen hadn't yet reached the point where he could even use a single C-rank Ninjutsu. Therefore, these Wind Release Ninjutsu, aside from increasing Yichen's knowledge, would no longer be of any help in the short term.

The three A-rank Ninjutsu are quite good. One Wind Release: Devastating Breath, which Yichen can't learn, but he's studying the remaining two Water Release very diligently. This should be of great help to him in developing and upgrading his Water Release Ninjutsu.

There's also some good news lately. Yichen's disciple, Kajiyamari, has finally completed the development of his first Ninjutsu, and amazingly, he has also recently achieved Wind Release: Breakthrough.

That's right, following in the footsteps of Chinoe, Kajiyamari has also embarked on the path to Jonin.

Yichen only learned of this upon returning to the East Front Camp. When asked why, he learned it was because he felt pressured by the rapid growth of Yichen's three newly recruited disciples. Under this sense of urgency, Kajiyamari miraculously Wind Release: Breakthrough.

After thinking it over carefully, Yichen felt relieved. Of his six disciples, only Kajiyamari was reasonably strong when they were in the Ninja Academy. It was alright when the team only had three people, because Ninjutsu- type ninjas are indeed at a disadvantage in the early stages. Therefore, Kajiyamari was able to accept that Kawakita was stronger than him at this stage.

Tomoko's Wind Release: Breakthrough was unexpected, and Kajiyamari didn't think much of it. Besides, Tomoko's foundation was too weak. Although Wind Release: Breakthrough, it was unknown how long it would take for her to become Jonin.

However, Yichen took in three more disciples, which made the Kajiyamari feel anxious.

Especially after seeing that Ogura Saki, who came from the Regular Class, was also trying to develop Ninjutsu, Kajiyamari couldn't sit still.

What truly forced Kajiyamari to achieve his Wind Release: Breakthrough was the insight that Ogura Saki shared when she consulted him about developing Ninjutsu. At that moment, it's no exaggeration to say that Kajiyamari felt a sudden enlightenment.

The person being consulted suddenly felt enlightened while listening to others explain the problem, and Kajiyamari became somewhat dazed.

By the time he came to his senses, more than an hour had passed, and Ogura Saki, who had been asking him questions, had already been taken away by Tomoko. As someone who had been through similar experiences, Tomoko knew that Kajiyamari should not be disturbed at this time.

In this miraculous way, Kajiyamari achieved Wind Release: Breakthrough and made significant progress in developing Ninjutsu. Kajiyamari's foundation was far better than that of Tomoko. Although Wind Release: Breakthrough much later, it is expected that Kajiyamari will become Jonin sooner than Tomoko.

Yichen felt somewhat ashamed. He had chosen Kajiyamari back then but hadn't been able to truly help him, and now Ogura Saki was the one guiding him. He felt he hadn't been a very good teacher.

What made Yichen even more embarrassed was that among the three —Tomoko, Kajiyamari, and Kawakita— Kawakita, the only one who hadn't yet Wind Release: Breakthrough, was no longer able to learn anything from Yichen.

Kawakita's path is completely different from Yichen's. Yichen can give Kawakita very little guidance. When he first graduated, Yichen's half-baked knowledge of swordsmanship could still give him some pointers, but now, in terms of understanding swordsmanship alone, Kawakita has surpassed Yichen.

The only consolation for Yichen was that he had brought Kawakita to the East Front Camp. At least there was Purple Lightning, a master swordsman, who would occasionally give him pointers.

Yichen is now hesitating whether or not to bring Tomoko and the other two back to the village.

He was going back to the village to learn S-rank Ninjutsu, and the three new disciples would definitely be going back with him. However, the three veteran disciples were all already Chunin, so theoretically Team One no longer existed. They should go their separate ways now.

But Yichen subconsciously felt that the three of them were still young, and it was too early for them to leave. After all, they were indeed quite young.

In the end, Purple Lightning saw through Yichen's hesitation and persuaded Yichen.

Yichen disbanded Team One, took all three of them back to the village, and left the rest to Ōnoki to arrange their future.

Upon returning to the village, Yichen went to collect his S-rank Ninjutsu. He had already reviewed the list of S-rank Ninjutsu and selected the Ninjutsu he wanted to learn.

Originally, Yichen planned to learn the Ultra-Added-Weight Rock Technique. This Ninjutsu, if used properly, could suppress Tailed Beast, and it was originally Yichen's first choice, since he didn't have a good way to deal with Tailed Beast yet.

However, after being reminded by Ikura, Yichen changed his mind and realized that when choosing Ninjutsu, he should consider Space-Time Ninjutsu. This was not only to deal with Minato Namikaze, but also to deal with Obito Uchiha might turn evil in the future.

Ultimately, Yichen chose Sensory Ninjutsu Ninjutsu. That's right, Sensory Ninjutsu. However, unlike the Sensory Ninjutsu Yichen had learned before, this S-rank Sensory Ninjutsu did not require Hand Seals, did not require deliberate sensing, and did not require touching the ground with a finger.

This S-rank Ninjutsu can be described in one sentence: it's a passive skill.

Whenever there is Chakra fluctuation, a ninja who knows this S-rank Ninjutsu will naturally be able to detect it.

In the original story Second Tsuchikage Mu this Ninjutsu. When facing Mu, no sneak attack was effective. Even if Mu was fully preparing the S-rank Ninjutsu, Dust Release: Original World Stripping Technique, Mu could still sense the danger coming from behind.

Yichen hoped to use this Ninjutsu to determine whether Obito would be in a Hollowfied state in the future.

The Iwa ninja's collection doesn't include Space-Time Ninjutsu, so Yichen couldn't find a way to truly Counter to Space-Time Ninjutsu. The only thing Yichen could think of was using S-rank Sensory Ninjutsu to judge his opponent's condition.

To be honest, Yichen wasn't sure if this Ninjutsu would work on Obito, but he wanted to give it a try.

It's still early for the Fourth Shinobi War, Yichen feels there will be other opportunities to learn powerful offensive Ninjutsu in the future. For now, it's more practical to learn this Sensory Ninjutsu first.

When Ōnoki saw Yichen's choice, he frowned, and then he thought of the method that Ikura had mentioned that day for dealing with Minato Namikaze.

Ōnoki shook his head and said, "The strength of the Flying Thunder God Technique lies in its speed. Even if you can sense the opponent's location, you won't have time to react. So you don't need to specifically learn Sensory Ninjutsu just to deal with the Flying Thunder God Technique."

"My teacher, the Second Tsuchikage Mu, also learned this Ninjutsu. He fought against the Second Hokage, who possessed the Flying Thunder God, but this Ninjutsu wasn't of much help to him."

"Uh~" Yichen hadn't expected this. Well, that makes sense. Both Mu and Senju Tobirama are second-generation, so it's normal that they've fought before.

After thinking for a moment, Yichen said, "I still want to learn this Ninjutsu. I want to see if it's useful."

Ōnoki thought for a moment and said, "Let's give it a try. Whether you can learn it or not, you can always learn a new one later. This Ninjutsu is of little help in combat."

Yichen's eyes lit up. There was such a benefit? He nodded frantically.

Ōnoki was so generous for one reason: he felt that Yichen's choice of this Ninjutsu was a sacrifice, a sacrifice for the village.

Secondly, because Yichen's foundation is far inferior to Ikura's, the time required for Yichen to truly complete his transformation will be much longer than for Ikura. Yichen should have time to learn two S-rank Ninjutsu.

"This Ninjutsu is not easy to learn; it's said that even the Second Lord was able to master it by pure chance. If you feel you can't learn it, don't dwell on it. Don't waste too much time; come and learn a new Ninjutsu as soon as possible."

Yichen nodded; no matter what Ōnoki said now, he wouldn't change his mind.

Ōnoki opened the Sealing Scroll to the appropriate position and released the seal. After confirming that Yichen had completely memorized the Ninjutsu, he resealed it. Then, he placed a secret Sealing Jutsu in Yichen's mind before leaving the secret room with Yichen.
