Yin Release Initiation

The Little Rhino Dog and Little Chōmei looked at Yichen pitifully. They didn't understand why Son Goku was so stubborn, when he could have left the cage.

Yichen had described to them how terrifying it was to be in a cage.

Yichen thought for a moment and said to Son Goku, "Son Goku, for the sake of Little Rhino Dog and Little Chōmei, I can release the seal on you, but you cannot harm the Iwa ninja or the people of the Land of Earth."

"Furthermore, while Roshi is still alive, you cannot completely leave Roshi's body. Once Roshi dies, I can set you free. Do you agree?"

Son Goku looked at Yichen strangely. Yichen's suggestion was entirely in its favor, and it didn't understand why Yichen would do it.

In fact, Yichen's idea was very realistic. As long as Roshi agreed not to harm the Iwa ninja, then Roshi's biggest drawback as Jinchuriki would be eliminated. No matter how you look at it, it would be beneficial to the Iwa ninja.

The only risk is that once the seal on Roshi loses its ability to restrain Son Goku could break free at any time and launch an attack on the Iwa ninja if he breaks the agreement.

But Yichen understood these Tailed Beasts; they were actually just like ninjas—they had thoughts, feelings, and a sense of pride. As long as Son Goku agreed in front of Little Rhino Dog and Little Chōmei, they definitely wouldn't go back on their word.

Son Goku was somewhat tempted. After hesitating for a moment, he finally snorted and said, "I don't need your sympathy. I can break the seal myself. Once I break the seal, the first thing I'll do is cause trouble for your Iwa ninja."

The Little Rhino Dog timidly called out, "Son Goku."

The Little Rhino Dog didn't understand why Son Goku disliked Yichen and Iwa ninja. It thought Yichen and Iwa ninja were both great.

Son Goku frowned slightly upon hearing the Little Rhino Dog's barking, but remained silent.

Yichen thought for a moment and said, "Son Goku, how about this? I'll be staying with Roshi for a while, so I'll release you for now, and we can discuss how to resolve this when I leave."

Seeing that Son Goku was about to say something, Yichen preemptively said, "Son Goku, since you can't possibly run away while I'm with Roshi, you can just pretend you're out and give Little Rhino Dog and Little Chōmei a good talking-to."

This time, Son Goku didn't immediately refute it; it still felt that Yichen had ill intentions. It was about to carefully consider Yichen's purpose in doing so. But at this moment, the two little guys very cooperatively stepped forward and started to coax and plead with it.

In the end, Son Goku reluctantly agreed.

After leaving the Sealed Space within Roshi's body, Yichen directly released the seal's binding effect to everyone's astonished expressions.

Roshi stared in disbelief as the Four-Tails 'Chakra surged from his body. He tried to stop it, but the seal had been broken, and he was powerless to stop it.

However, the Four-Tails' rampage that Roshi had predicted did not occur. After the Four-Tails 'Chakra reached a certain level, it stopped increasing. The Chakra directly condensed into a small Four-Tails, about the same size as a Little Rhino Dog Little Chōmei.

Son Goku felt embarrassed to appear in such a small form, so he led the Little Rhino Dog and Little Chōmei to the side, ignoring everyone. Especially Roshi, whom Son Goku didn't even glance at.

Yichen didn't care about Son Goku's arrogance, nor did he explain to the others. He simply called Kawakita aside.

Kawakita's status is different now; he still holds the title of advisor to Iwagakure. Kawakita hasn't been back to Iwagakure for a long time, so Yichen told Kawakita in detail about some of the major events that have recently happened in the village.

The Land of Grass isn't far from the Iwagakure, and Ōnoki didn't spend much time on his round trip. Not long after Yichen finished explaining things to Kawakita, he returned with Katsuya and the others.

Yichen solemnly registered Little Chōmei's Ninja ID, then issued it Ninja ID and put Iwa Ninja forehead protector on it. Then he pulled Katsuya and began to discuss with him what he had sensed with his using Mind's Eye in the shrine.

Katsuya himself tried to enter the temple and sense it, but unfortunately, he didn't hear anything.

When Yichen was discussing things with Katsuya, he called Natsuki over so she could listen in as well. After this incident, Yichen understood that Natsuki's talent lay in Yin Release.

Yichen is actually very suitable for learning Yin Release. His soul strength far exceeds that of ordinary people. It would be impossible for him to learn the first S-rank Ninjutsu, Mind's Eye, a Sensory Ninjutsu.

However, because Iwagakure lacked Yin-Yang Release- Yin-Yang Release techniques and researching them was too difficult, Yichen did not choose Yin Release from the beginning. Instead, he chose the Five-Attribute Ninjutsu.

Later, because Yichen's main task was to unify the Five-Attribute rather than to Yin-Yang Fusion Yichen, he never spent time learning and developing Yin Release.

But now the situation is different; there's a copy that allows direct research into Yin Release. As the Tsuchikage Yichen, it's Yichen's responsibility to open up a new area for the village.

Therefore, although Yin Release is not the focus of Yichen's research at present, Yichen still plans to spend time studying it carefully to see if he can gain anything.

Yichen is very professional in developing new fields. He has participated in various techniques, including Sealing Jutsu, Lightning Release, Genjutsu, Space-Time Ninjutsu, and Yichen Senjutsu. He has also developed his own Porcelain Release from scratch. It seems that Yichen has not participated in the development of Medical Ninjutsu.

Therefore, even though Yichen doesn't have much of a clue about Yin Release yet, he is still full of confidence.

Yichen divided the study of Yin Release into two steps: first, to help Katsuya get started; second, to leave the work to Katsuya.

So although it's currently Yichen and Katsuya discussing things, it's actually mainly Yichen trying his best to describe what he senses to Katsuya.

In the days that followed, Yichen lived a very monotonous life, spending his days either researching Yin Release or instructing the ninjas present on their training.

Ōnoki and his group didn't have a specific destination in the first place, so they weren't averse to staying near the temple. Plus, they were able to get occasional guidance from Yichen, so they couldn't wait for Yichen to stay and study for a while longer.

Believe it or not, whether it's just psychological or not, two people have actually made significant progress in their abilities during the three months or so they've been here.

Both were Anbu) guarding Han, Chunin had become Quasi-Jonin. This made everyone else extremely envious, especially the last Chunin in the Anbu Squad, who was incredibly anxious.

During these three months, the happiest people were Uzumaki Riori, Little Rhino Dog, and Little Chōmei. Every day, Uzumaki Riori would use the excuse of training to spar with others and have a great time.

Little Rhino Dog and Little Chōmei also became close with Uzumaki Riori. The two little ones were the ones who fought the most with Uzumaki Riori and were inseparable from each other every day.

Don't let their small size fool you; they are Tailed Beast after all, and their strength is considerable. Uzumaki Riori's Shadow Clone tactic might not be able to outlast them.

The two tailed beasts, one human and two Tailed Beasts, were evenly matched and had a lot of fun.

With Ōnoki watching over things, Yichen didn't need to worry. His job was to keep Natsuki from constantly trying to get involved.

Three months have passed, and Yichen, Katsuya, and Natsuki have all made significant progress.

The biggest gain was the set of Yin Release theory systems that Katsuya summarized.

After combining the half-guessing and half-spoiler-like guidance from Yichen, the transmigrator Katsuya concluded that there are two paths to Yin Release cultivation, each with four stages.

The first path is illusory. The first stage involves mobilizing the power of the soul, that is, spiritual power. The second stage involves sensing the existence of the soul. The third stage involves being able to use the soul to directly attack and kill the enemy's soul. The fourth stage involves the soul breaking free from the body and existing independently.

The second path is real. The first stage involves strengthening the soul to defend against soul-type attacks. The second stage involves using semi-physical Yin Release techniques to influence the enemy's soul. The third stage involves materializing the soul to attack the enemy's physical body. The fourth stage involves creating life using physical Yin Release.

The former, the second stage is represented by the Ninjutsu: the Mind Transfer Jutsu of the Konoha Yamanaka Clan; the third stage is represented by the Ninjutsu: the Spirit Transformation Jutsu; the fourth stage is represented by the Sage of Six Paths.

The latter, the second stage is represented by the Ninjutsu: Shadow Imitation Jutsu; the third stage is represented by the Ninjutsu: Shadow Binding Jutsu; the fourth stage is represented by the figure: Black Zetsu, or rather, Kaguya, who created Black Zetsu Kaguya Otsutsuki.

According to Yichen and Katsuya's analysis, Genjutsu attacks follow the same path. However, the users of Genjutsu vary in strength; the strong may be at the second stage, while the weak may be at the first stage.

Yichen speculated that the Sharingan of the Uchiha Clan might not be a simple Yin Release, at least not an ordinary Yin Release, so he did not classify it.

The second path was abandoned because, apart from the Nara Clan, Yichen could find no reference point. Yichen and his companions focused their research on the first path.

Three months ago, Katsuya was truly in the first stage. Natsuki had outstanding talent; although she hadn't experienced the first stage, her starting point was vaguely at the threshold of the second stage. Yichen was also in the first stage, but with the help of Mind's Eye and the Little Rhino Dog's Chakra, he barely reached the second stage.

After three months of research and practice, Natsuki, who had the best talent but the worst foundation, barely made it into the second stage. Don't underestimate the second stage; you should know that the fourth stage is at the Sage-level, and even entering the third stage can barely be classified as having the Kage-level Combatant being.

So, having barely entered the second stage, Natsuki successfully became Quasi-Jonin. However, Natsuki's strength Quasi-Jonin should be at the bottom among her peers, because she lacks matching attack methods. She doesn't know Genjutsu!

Katsuya had the least talent, but this path suited him best, and he barely made it into the second stage. Katsuya's theoretical knowledge and foundation were the best among the three, and his improvement was gradual and solid. His previous experience in developing Genjutsu made his progress the most natural among the three.

Just a few days ago, Katsuya was finally able to sense the strange sounds inside the temple.
