Naruto: This Uchiha is too innocent.

What makes Uchiha Sora so confident that he can teach Nagato how to use the Rinnegan correctly?

Of course, he could vividly describe to Nagato the techniques he used in the original work. In the original work, Nagato spent more than twenty years studying the development of the Rinnegan, and for him, the most suitable and comfortable techniques had already taken shape over the long years.

It's important to understand that Nagato's Rinnegan wasn't innate; therefore, he could only utilize its basic abilities. Unique abilities like Madara Uchiha's Limbo: Border Jail and Sasuke Uchiha's Amenotejikara were completely beyond his reach.

In other words, Nagato could only explore and develop the basic abilities of the Rinnegan. Undoubtedly, in the future, Nagato's mastery of the Rinnegan surpassed that of other users.

At present, what Uchiha Sora can do is to teach Nagato so that he can master the powerful abilities of the Rinnegan after it has been developed.

Nagato's most proficient Rinnegan ability was undoubtedly the Six Paths of Pain.

Because Nagato summoned the Ten-Tails, and his Rinnegan was transplanted, this act caused immense damage to his body, leaving him in extremely poor health, even more fragile than an ordinary person—a veritable sickly weakling. Therefore, developing close-combat abilities would be of little use to Nagato. The most suitable approach for him was to maximize the potential of his puppet techniques.

"I will help you kill Hanzo." Uchiha Sora's gaze was firm as he stared directly into Nagato's eyes without the slightest fear.

Nagato remained silent; he could see no trace of deceit in the boy's eyes. In other words, this young man was absolutely certain he could help him further develop his Rinnegan.

This sounds unbelievable. These Rinnegan have been with Nagato since he could remember. For over a decade, he had only a vague understanding of how to use them. When Jiraiya first saw these eyes, he decided to become their mentor. However, even with Jiraiya's vast knowledge, he was equally clueless when faced with these mysterious Rinnegan.

Later, when the Akatsuki organization was founded, Yahiko devoted a great deal of manpower and resources to searching everywhere in order to find out the secret of these eyes, but in the end he still found nothing.

At this moment, the Uchiha boy he had just rescued was confidently declaring that he could help him truly control those eyes.

"Ha, ha, ha ha!" Nagato suddenly burst into wild laughter, a laugh filled with bitterness and resentment. The intense emotions overwhelmed his already ailing body. His laughter abruptly ceased, followed by a violent coughing fit, each cough seemingly exhausting all his strength. Dark red blood gushed from the corners of his mouth, a horrifying sight against his pale skin.

Upon seeing this, Konan was shocked and instantly flashed to Nagato's side, gently placing her hands on his back and softly comforting him.

After a long while, Nagato slowly recovered. An unnatural flush appeared on his previously pale face. He slowly opened his eyes, gazing intently at Uchiha Sora, his voice low and hoarse: "If... you could have appeared sooner..."

If Uchiha Sora had appeared sooner, he might have been able to control those eyes sooner. With that immense power, he might have been able to prevent that tragedy, to prevent... Yahiko's death.

Thinking of this, Nagato slowly closed his eyes, and a terrifying pressure suddenly emanated from his body. That pressure spread out as if it were a tangible force, as if it could crush everything around it.

Uchiha Sora truly felt the overwhelming pressure emanating from the Rinnegan, and was utterly shocked. He was secretly amazed that the Rinnegan was indeed worthy of its reputation as the pinnacle of ninja eye techniques! Under the impact of this pressure, the rocks beneath his feet could not withstand the weight and cracked, making a "crackling" sound.

After a long while, Nagato calmed down with Konan's comforting words. He slowly opened his eyes, his face expressionless.

"Deal reached."

Upon hearing this, Uchiha Sora breathed a sigh of relief, then asked in a deep voice, "Where is Hyuga Ame?"

"That girl with the white eyes? You'll see her once you fulfill your promise," Nagato said calmly. He had truly grown a lot; aside from his emotional outburst just now, he had everything under control.

Even if Uchiha Sora wanted to ask, he knew there would be no result. In the end, it was Nagato who saved them this time, otherwise he and Hyuga Ame would have been dead. Therefore, the control was always in the other party's hands.

……

"What should I do?" Nagato slowly stood up and walked steadily towards Uchiha Sora.

Uchiha Sora pondered for a moment, then looked at Nagato and asked, "To what extent have you developed the Rinnegan?"

Upon hearing this, Nagato remained silent, calmly extending his hand slowly to the side. In an instant, an extremely terrifying suction force erupted from his palm, and a huge hole was sucked into the distant rocks by this powerful suction.

Immediately afterward, Nagato's eyes narrowed, and a terrifying repulsive force erupted like a surging tide. The large rock that had just been sucked into the hole was instantly crushed into countless tiny fragments under the violent impact of this repulsive force. At the same time, a thick layer of white mist filled the cave, which was the dust raised by the shattered rock.

"Shinra Tensei and Bansho Ten'in... are there any others?" Uchiha Sora asked calmly.

Nagato glanced at Uchiha Sora without leaving a trace, somewhat surprised that the latter could name the technique.

"Besides these two moves, I also know sealing techniques, soul-absorbing techniques..." Nagato slowly began, explaining in detail the abilities he possessed.

Uchiha Sora listened quietly to Nagato's description, nodded slightly, and pondered in his heart: Judging from the current situation, Nagato has mastered most of the most basic abilities of the Rinnegan. In this way, the success of the plan is guaranteed.

"Have you mastered Planetary Devastation?" Uchiha Sora asked.

Shinra Tensei, Bansho Ten'in, and Chibaku Tensei are Pain's signature killing moves. Other techniques aside, Nagato must master these three.

"Planetary Devastation?" Nagato was slightly taken aback and asked in return. Clearly, since no one had ever taught him, he was unaware of this powerful ability.

"Simply put, you use the Rinnegan to highly compress your chakra. As long as you can compress the chakra into a black sphere, it means you've succeeded," Uchiha Sora patiently explained the principle.

Nagato seemed lost in thought, lowering his head slightly, a thoughtful expression in his eyes. He had never tried compressing chakra before, so he had no idea what the effects would be. However, after a moment, he raised his head and said, "I'll give it a try."

Having said that, Nagato immediately began to act, mobilizing all the chakra in his body. The immense chakra flowed like a babbling brook, converging into a river, rushing along his meridians and frantically gathering towards his palm. If Hyuga were here, she could clearly see that the chakra in Nagato's palm was rapidly spinning in a spiral, constantly being compressed and condensed.

Soon, an extremely pure black sphere quietly took shape in Nagato's hand. The black sphere was as black as ink, faintly exuding a terrifying aura that sent chills down one's spine.

Upon seeing this, Uchiha Sora's eyelids twitched violently, and he hurriedly shouted, "Alright, alright, whatever you do, don't release it! If this thing is released, this area will probably be razed to the ground!"

Nagato's gaze was fixed on the black sphere in his hand, his eyes gleaming. He could clearly feel the terrifying power contained within it. The next moment, his expression hardened, and he pressed his palm down forcefully, forcibly crushing the black sphere, which dissipated into wisps of chakra into the air.

"Hmm... Next, I'd like to ask, can you use the black rods?" Uchiha Sora asked after a moment's thought. The black rods are a basic ability of Rinnegan users, and also an extremely practical weapon.

Nagato nodded slightly, and with a thought, a black rod about a meter long instantly appeared in his hand.

Uchiha Sora looked at the black rod and felt a surge of emotion. This seemingly ordinary weapon was actually a top-tier weapon, possessing the noble Yin-Yang Release attribute, second only to the power of the Six Paths.

"Shorter, thinner," Uchiha Sora said, looking the black rod up and down.

As soon as he finished speaking, the black rod began to slowly shrink.

"Continue, make it even smaller than your ring finger."

The black rod continued to shrink as he requested, and before long it formed a thin black rod only a few centimeters long, perfectly meeting Uchiha Hollow's standard.

"What's the use of this?" Xiao Nan suddenly asked, looking at the little black stick.

"Well..." Uchiha Sora grinned, "It can be used as an earring and a nose ring."

Xiao Nan: ……

"Next, we need a corpse," Uchiha Sora said.

"A corpse? Where am I supposed to find you a corpse..." Before he could finish speaking, Nagato paused, silently turning to look at Konan, as did Uchiha Sora.

Seeing the two people's gazes, Xiao Nan remained expressionless. "Wait for me for half an hour." After saying that, she turned into a shower of white paper and disappeared to hunt corpses.

"What a convenient paper-based technique..." Uchiha Sora reached out and picked up a piece of paper, remarking with admiration.

"If you're envious, kill Hanzo, and I can have Konan teach you."

"Sigh, beautiful paper jutsu is meant for beautiful girls, it's not appropriate for me to use it." Uchiha Sora folded the white paper in his hand into a paper crane, but unfortunately he couldn't bring the paper crane to life like Konan. With a gentle push, the paper crane fell to the ground.

"Just like Konan said, you really are special." Nagato looked at Uchiha Sora's childish behavior and slowly reached out his hand.

"Hey, keep your hand away from me, I don't want you to extract my memories."

Nagato was taken aback, then smiled silently. This was probably the first time he had smiled since Yahiko's death, though it was a helpless smile.

The atmosphere fell silent; with the Rinnegan involved, the two seemed to have run out of things to say.

Uchiha Sora didn't dislike this deathly silence; on the contrary, he preferred this feeling, where he didn't have to think about anything, his thoughts seemingly swallowed up by the silence.

After a long while, Nagato's voice rang out.

Thank you.

Uchiha Sora was taken aback, thinking to himself, "What did I do? What do you have to thank me for?"

"We need to thank you for letting Xiaonan try to make explosive tags. If it weren't for the explosive tags, we might be dead already."

Upon hearing this, Uchiha Sora suddenly understood. So that's what it was about. In that case, Konan has already started to develop towards the goal of six hundred billion explosive tags?

And now he's teaching Nagato how to use the Rinnegan. In a sense, he's pushing the plot forward? No wonder the system isn't issuing any more missions.

Shaking his head, he said, "Even without me, Xiao Nan would have discovered her talent in this area sooner or later."

……

The atmosphere fell silent again.

After a long silence, it was Uchiha Sora who spoke this time: "I remember telling Konan to be careful of Hanzo, so why did things turn out this way?"

As he spoke, his gaze lowered. He had indeed warned Konan to be careful of Hanzo, and to some extent, he wanted to change the established course of events in this matter.

But Yahiko still died, and Nagato remained in the same state, meaning that his warning had not changed anything.

Nagato, his eyes also lowered, said, "I'm sorry, Konan did mention it, but... Yahiko didn't take it seriously."

At that time, the Akatsuki organization and Hanzo had a cooperative relationship, and it could be said that there was a subtle possibility of further development. Yahiko certainly wouldn't take Uchiha Sora's words about being just a child seriously.

"Uchiha Sora, what are your thoughts on this endless war?" Nagato asked inexplicably.

Uchiha Sora looked up at him. Someone had asked him this question before, but he hadn't expected Nagato to ask it again.

"My opinion? Of course, I despise it. Who doesn't despise war?"

"Yes, who doesn't hate war?" Nagato said in a low voice. "Do you know? My parents died in the war... killed by Konoha ninjas. So, I hate war, I hate it terribly."

Uchiha Sora raised his hand. "Speak first. Although I am from Konoha, you can't blame me for your parents' deaths."

"Heh." Upon hearing this, Nagato chuckled inexplicably. "I know that Konoha killed my parents because of our differing stances."

"In war, there is no right or wrong, only different perspectives. The only one at fault is the battlefield itself. Konoha killed my parents, yet it gave me hope..."

"Him? It must refer to Jiraiya," Uchiha Sora thought to himself.

"So at that time I didn't hate Konoha, and I never thought about revenge, but now... because of Konoha, I have lost someone I cherished again."

"Ahem, that's Danzo, from Root, it has nothing to do with me," Uchiha Sora quickly added a disclaimer.

Nagato glanced at him, shook his head, and calmly said, "The Akatsuki's hope was meant to bring hope to the ninja world, but the ninja world gave the Akatsuki despair first. Do you think we were wrong?"

Uchiha Sora thought for a moment, "The idea is right, but the process is wrong."

"What do you mean?"

"The Akatsuki's starting point was indeed good—to create a ninja world without war. Unfortunately... their methods were wrong. You didn't intend to use force, but instead wanted countries to understand each other. That's too naive. Humans are greedy, and mutual understanding is too greedy." Uchiha Sora shook his head.

Nagato remained silent, seemingly pondering the deeper meaning of those words. After a long while, he frowned and asked, "Then what do you think is the best way to stop the war?"

"Well... naturally, it's about using violence to suppress violence, using unparalleled force to suppress the entire ninja world, which is... unification."

"Unification?" Nagato was taken aback. He had never considered this idea before, because achieving unification would inevitably involve war, and it would be the most terrifying war in history.

If that were the case, before unification, there would be endless people like them who would suffer the same fate of losing their families and homes.

"This is too cruel," he said instinctively.

Uchiha Sora gave a sinister smile, staring intently at Nagato. "Yes, the process of unification is indeed cruel, but what about the ideal world you wanted to create? What about the peace of the ninja world you wanted to achieve through mutual understanding?"

"Don't joke around. It was just Kusagakure that was provoked by Danzo. It was just three forces, and your ideal country was already destroyed."

"Not to mention the entire ninja world, with hundreds or thousands of countries. Mutual understanding? Perhaps hell or heaven exists."
