Starting as a pirate, he rose to become the strongest Shinigami in Soul Society.

Chapter 389 Madara Uchiha arrives at Ryuchi Cave, Sasuke meets Itachi.

After some deliberation, Madara Uchiha decided to personally visit the Spirit Lord who had sealed the Rinnegan in the heavens.

He could never return to the Pure Land; if he did, he would fall into eternal slumber. Therefore, the only place he could go was Ryuchi Cave.

After a long and winding journey, leading the remaining members of the Akatsuki, they finally arrived at the desolate mountain where Ryuchi Cave was located.

Then I noticed that the area looked like it had just been hit by an earthquake, which puzzled me greatly.

Meanwhile, inside the Ryūchi Cave, seeing that Bane had returned to the Pure Land, the others went about their own business.

Orochimaru originally intended to continue cloning Sharingan, etc. During this time, he had already copied many three-tomoe Sharingan. His plan was to wait for Bane to return and then start the next stage to see if he could seize the Sharingan's bloodline limit with his soul power.

However, now that he has just restored his soul to its full potential, his attention has completely shifted to the path of the integration of body and soul.

Previously, due to the incompleteness of his soul, he had been unable to practice the improved spiritual transformation technique by Bane. How could he possibly endure it now?

"Sasuke, let's go, it's time for training," Nami called out to Madara Uchiha and Sasuke.

Although Orochimaru was Sasuke Uchiha's nominal teacher, in reality, almost everyone in Ryuchi Cave, except for Bane, was guiding him.

A few days ago, even the two Yugitos helped him develop and improve his Lightning Release ninjutsu.

This led to Sasuke Uchiha having an exceptionally fulfilling life in Ryuchi Cave, and Nami's invitation for him to train together was a kind of practical training exercise.

"Yes, Nami-sama," Sasuke Uchiha replied immediately.

The two quickly emerged from the cave and traversed the complex passages within Ryuchi Cave, chatting as they went.

"Lady Nami, I heard from Waver that you opened the final gate of the Eight Gates technique a couple of days ago?" Sasuke Uchiha asked with a hint of curiosity.

Hearing this, Nami said with some pride, "That's right, after spending so much time, I've finally mastered the Eight Gates. How about that? Aren't I amazing?"

"Incredible!" Sasuke Uchiha praised without reservation. "So, what technique are you practicing right now?"

"Paper Release Technique and Yin Seal." Nami didn't hide anything and said calmly, "The Paper Release Technique can be used in conjunction with my Mutual Explosion Tag Technique. I have already mastered a part of it and can immediately create nearly a thousand explosion tags with Paper Release. Combined with the Mutual Explosion Tag Technique, it is quite terrifying. As for the Yin Seal, I only started researching it in the last few days."

"Do you really need to learn the Yin Seal?" Sasuke Uchiha asked, somewhat puzzled.

Because Ryuchi Cave is completely open to knowledge, even though Sasuke Uchiha didn't study there, he would often read those random techniques in his spare time to broaden and enrich his horizons.

He had also seen the Yin Seal. It was an S-rank medical ninjutsu developed by Tsunade, the current Fifth Hokage of Konoha. It was not a forbidden technique, but it was definitely a secret technique.

Its main effect is to store and seal a large amount of chakra in the body on ordinary days, and use it at critical moments to instantly restore one's physical functions to their peak state, while enhancing physical fitness and strength. It also achieves a state of "pseudo-immortality", such as fully releasing the Yin Seal and activating the "Hundred Healings Technique". Even if the body is cut into two pieces, as long as it can be reconnected, it can still be fully restored. It is a powerful ninjutsu.

This would indeed be very valuable to an ordinary person, but for Nami, an immortal phoenix, would she be afraid of this?

"Of course it's necessary, and it's absolutely necessary. I thought so at first too, but after talking with Orochimaru, he said that this technique is quite good for restoring stamina. And after a few trial training sessions, I found that it is indeed true. Releasing the chakra sealed in my body can quickly restore my stamina. And you should understand how important stamina is to me, right?" Nami said with a smile.

Sasuke Uchiha nodded in understanding, saying, "I see."

Physical strength is certainly important to Nami. Ultimately, the limitation of her Phoenix ability is the limitation of physical strength.

This is why Nami pays great attention to developing her physical abilities. Back in the One Piece world, she was constantly training in the Six Powers, Haki, and martial arts, continuously improving her physical capabilities. Although she never had many opportunities to showcase her skills and was no match for monsters like Bane, she still persisted.

Now, having become an immortal phoenix, and having studied a great deal of taijutsu-related knowledge in the ninja world, all for the purpose of further enhancing his physical abilities and continuously unleashing the power of the immortal phoenix.

The Yin Seal can effectively solve her endurance problem, allowing her combat power to be fully unleashed!

"A few days ago, Yugito secretly trained you in Lightning Release. Has there been any progress?" Nami asked Sasuke with concern.

"There are some." Uchiha Sasuke was quite frank.

Although he occasionally misses Konoha, where he used to live, Sasuke Uchiha now believes that the environment and atmosphere of Ryuchi Cave are much better than those of Konoha.

Perhaps it was because of its small size; after all, there were only so many people, and it seemed that a few of them were wandering around, whom he had never met.

In short, everyone got along very well, and they all took good care of him. They trusted each other a lot. He was the youngest and received the most care from everyone, which made Uchiha Sasuke feel like he had returned to his childhood when his family was still around.

It was precisely because of this feeling that he genuinely recognized Ryuchi Cave. Although Uchiha Sasuke appeared to be very aloof on the surface, he was actually very soft-hearted. Because he had lost something in the past, he cherished what he had now even more.

"When Kakashi-sensei left to participate in the war on the front lines, he taught me the Lightning Release ninjutsu related to Chidori, and told me to practice and study it on my own in the village. Although I have gained some knowledge, I have not truly mastered it. A few days ago, the head of the Wood Demons helped me explain it, and she also inspired me to develop many extensions for subsequent ninjutsu," said Sasuke Uchiha.

As they were saying this, the two of them had already arrived at the back of the mountain.

"That's good. Yugito is a very powerful ninja, one of the strongest in Kumogakure. You should learn from her." Nami replied with a smile, then asked, "What about the development of the Mangekyou Sharingan? Have you noticed any progress lately? Has Orochimaru's theory been effective in practice?"

When this was mentioned, Sasuke Uchiha said with some excitement, "Yes, absolutely. Perhaps if we had known about this training method to enhance the Sharingan's power earlier, many things could have been different. Because of the Sharingan, many people thought that our Uchiha clan was inherently evil."

As the Second Hokage, Tobirama Senju never concealed his loathing and prejudice against the Uchiha clan.

As a result, many people in Konoha were also influenced by him. In addition, the powerful Uchiha clan at the time was quite arrogant and disdained to associate with outsiders, so he was labeled as "born evil".

However, Tobirama Senju's belief that the Uchiha clan was inherently evil was not without theoretical support, most notably their clan's bloodline limit, the Sharingan.

Extreme mental stimulation is required to enhance one's eye power and continuously elevate the power of the Sharingan.

Many extreme members of the Uchiha clan often harm those around them to stimulate their own mental state.

Therefore, mentally ill individuals often emerge from the Uchiha clan, disrupting village order, causing scandals, and becoming slaves to power.

Before arriving at Ryuchi Cave, Sasuke Uchiha had already awakened the three-tomoe Sharingan. As for the Mangekyou Sharingan, he hadn't actually thought about it at the time, but Orochimaru's research on the Sharingan didn't stop.

After joining the Ryuchi Cave faction, Orochimaru also began to learn and master powers such as Haki. In the process of training Haki, Orochimaru realized that the power of Haki is actually the tempering of one's own mental power, so as to reach the point where mental power can manifest and influence reality.

Whether it's Armament Haki, Observation Haki, or even Conqueror's Haki, which is mastered by only a very few people, they are all the same in this essential aspect.

Not a single mistake, not a single poem, not a single post, not a single piece of content, not a single look!

Cultivating domineering aura involves constantly refining and strengthening one's mental power. Masters of domineering aura are often people with unwavering will, perseverance, powerful presence, and abundant energy.

In the ninja world, although there are some techniques for enhancing mental strength, none are as effective as Haki.

After all, this is the essence of the world, and over hundreds and thousands of years, countless people have continuously improved it, bringing it to near perfection.

So after understanding the underlying logic of Haki, Orochimaru immediately thought of the Sharingan. The Sharingan's power requires mental strength to support it. However, the Uchiha clan went astray, linking the development of the Sharingan with mental stimulation, using accidental events to stimulate the mind and thus improve the power of the eyes.

The fact that this method has been continued by the Uchiha clan to this day is certainly due to its advantages. It requires almost no training; as long as one dares to act crazy, there is a high probability that one can gain power.

Furthermore, by increasing pupil power, one can stabilize the suddenly enhanced mental power, which is extremely efficient.

The side effects are also obvious: almost everyone suffers from neurosis, bipolar disorder, or paranoia.

Sasuke Uchiha, despite his young age, was actually a fanatic. As for Itachi Uchiha, who killed his entire family, it goes without saying that no matter what his reasons or stance were, there's no way to whitewash what he did. Calling him a lunatic would be an understatement; it's an attempt to whitewash him.

As for the rest of the Uchiha clan, most of them have some kind of problem.

In contrast, domineering aura is a stable increase in spiritual power, a gradual and solid growth achieved through persistent effort.

There were no side effects, and through training in Haki, Uchiha Sasuke could already feel his eye power increasing and his mental strength becoming more abundant!

Therefore, he was extremely excited. This behavior undoubtedly confirmed that it was only natural for him to continue cultivating along this domineering path and awaken the Mangekyou Sharingan. As for what the Eternal Mangekyou Sharingan might become, we'll talk about that later.

Orochimaru is cloning the Sharingan, isn't he? Maybe he'll get some unexpected gains from that?

Just as Nami was about to continue her conversation with Sasuke about these matters, she suddenly stopped, frowned slightly, and said, "Someone is approaching!"

Sasuke Uchiha didn't notice anything, but he trusted Nami completely and immediately became alert.

Longdi Cave is located in a remote, desolate area where outsiders are rarely seen. Therefore, any unusual activity there must be something wrong.

Sure enough, a few minutes later, a commotion came from the dense forest, and before long, Madara Uchiha and the others came out.

"Oh my, if you've met someone here, they're probably all connected to Ryuchi Cave, right? Little girl, are you from Ryuchi Cave?" Uchiha Madara asked with a hint of curiosity.

Before Nami could even finish her sentence and assess whether these people posed a threat, Sasuke Uchiha beside her suddenly turned red with rage!

"Uchiha Itachi!!!" Uchiha Sasuke roared, his voice filled with hatred.

Without saying a word, he slipped his sleeve, produced a kunai, and charged straight at Uchiha Itachi.

Madara Uchiha seemed to only then realize what was happening, raising an eyebrow and saying, "Uchiha, huh? That's quite unexpected."

Meanwhile, Itachi Uchiha calmly watched Sasuke Uchiha charge towards him and said, "You can't even control your most basic emotions. You're truly a failure as a ninja, my foolish little brother."
