"Edo Tensei! It is recorded in the Konoha Scroll of Seals. The purpose of this technique is to use a life as a sacrifice to summon a soul from the Pure Land."
Kagetsu didn't go into further detail to explain this forbidden technique to Nagato, but instead used it as an example to prove that souls from the Pure Land could indeed return to the ninja world in a different form, once again interacting with this world.
Of course, the summoned beings would still be controlled by the user under the limitations of the jutsu.
But as a forbidden technique, it naturally carries risks.
For example, if the summoned deceased is too powerful, or if they have knowledge of the Edo Tensei technique, the user might accidentally suffer a backlash from the deceased and lose control.
"So, you think the person controlling White Zetsu's actions is aiming for the resurrection of the dead?"
Nagato was not foolish.
Kagetsu had already hinted at the issue so clearly that even someone slow like him could guess some of the reasons.
Based on what he knew of Kagetsu, he wouldn't mention an issue and then go off on unrelated topics for no reason.
"Why wouldn't it be possible? The Rinnegan, the legendary eye said to control life and death. But the Pure Land has its own rules.
Edo Tensei allows the dead to briefly return to the ninja world, but it requires the sacrifice of a life. So what about the Rinnegan? What is the cost of its resurrection power?"
"The user's life?" Nagato followed Kagetsu's words, subconsciously drawing connections, his face growing pale.
"Most likely. If this technique truly exists, then perhaps it is a forbidden jutsu that a ninja can only use once in their lifetime."
In fact, if there's a loophole, as long as the Rinnegan is not destroyed and a new host is found for it, the so-called resurrection power could continue to be used, bringing back whoever is needed.
As long as the price is enough, the Pure Land does not set any thresholds.
"Why me?" Nagato asked in confusion. He didn't think of himself as special. When he had the Rinnegan before, he thought maybe he was special, but now he knew that the Rinnegan didn't truly belong to him.
Or rather, he had merely become its vessel.
"Maybe it's because of your unique constitution," Kagetsu replied. Follow current novels on novel•fire.net
"Constitution?" Nagato suddenly remembered that he did indeed have the bloodline of a certain clan.
"The Uzumaki clan, a powerful ninja clan famous for their sealing techniques. They have a good alliance with the Senju clan and Konohagakure.
But aside from their sealing techniques, the Uzumaki clan's constitution is also incredibly strong! Some of their uniquely gifted members can transform their constitution into a specific ability.
For example, some are skilled in sensing, having a form of 'mind's eye' that allows them to sense others' locations and even detect certain emotions contained within chakra with great clarity.
There are also those whose bodies can heal injuries and restore chakra by having others bite them, replacing the need for medical ninjutsu.
And their chakra is extraordinarily abundant, which can manifest as a powerful force through sealing techniques.
Even the ordinary Uzumaki members possess physical abilities far superior to those of other ninjas, with exceptional recovery and chakra levels.
Some of the Uzumaki clan's physically powerful members even have bodies that rival those of the Sage Body."
Kagetsu said, glancing at Nagato before continuing: "Just the Sharingan, a Kekkei Genkai, when transplanted to another ninja, becomes such a heavy burden that even some Jonin would not wish to bear it.
And the Rinnegan, with its power far surpassing the Sharingan, places even greater demands on the body! Perhaps only a Sage's body could perfectly bear this power."
"So, because of my powerful constitution, I became the vessel for the Rinnegan?" Nagato clenched his fist.
"Your constitution is indeed powerful," Kagetsu said without hesitation. "I've examined your body, and in my opinion, your physical data far exceeds that of some members of the Uzumaki clan.
While the Uzumaki clan's abundant Yang-chakra grants them strong physical bodies, it also makes their lives incredibly resilient."
"At least with strong vitality, the price to pay is greater, and it can reduce unexpected incidents when performing the technique."
"Then, if Konan and Yahiko stay by my side, will they be burdened by me?" Nagato stared blankly at the land beneath his feet, his mind recalling the dangers and hardships he and Yahiko had experienced together since childhood, involuntarily thinking of some issues he hadn't considered before.
He wasn't as strong as he had imagined, so when facing danger, he couldn't truly protect Yahiko and Konan.
His battle with the White Zetsu Tobi made him realize this even more.
"I can't say for sure."
Kagetsu shook his head. If we don't consider conspiracy theories, it's hard to say if everything that happened in the original timeline had anything to do with Madara.
As a legendary figure on par with the First Hokage, Uchiha Madara might have many flaws, but when it came to Nagato, even until Nagato's death, there was no sign that Madara had placed any restrictions on him.
Maybe Madara, confident to the point of arrogance, thought that even after his death, his so-called will would extend, lingering in the ninja world to guide Nagato, so that in the end, Nagato would use the Gedo Art of Rinne Rebirth to summon him back to life from the Pure Land.
"However, he also needs your growth. When you grow and can use most of the Rinnegan's abilities freely, you won't need to worry about him doing anything to you.
If you're worried about Konan and Yahiko, you just need to stay close to them at all times." Kagetsu saw Nagato's worries and comforted him.
"Thank you!" Nagato knew that his presence couldn't prevent all troubles and dangers, but it was the method that gave him the most peace of mind and acceptance.
"If danger really comes, I can help." Kagetsu clapped his hands and said this while looking at Shisui, who was showing signs of waking up.
Nagato's eyes instantly brightened. Previously, his worries had led him to a mental deadlock, but Kagetsu's words helped him break out of that cycle.
Earlier, when Yahiko was severely injured, they were helpless and could only watch him slowly move toward death. But under Kagetsu's treatment, Yahiko had recovered.
Not only did Kagetsu save Yahiko's life, but he also made his body and strength even stronger!
Even when Yahiko was on the brink of death, Kagetsu's medical techniques and strength had gained the absolute trust of Nagato and his group.
They weren't sure about Tsunade, the greatest medical ninja, but judging by the situation, it seemed like Kagetsu might not be far behind her in terms of skill.
Thinking this, Nagato instinctively reached up and touched the cold, coiled little white snake hidden in his sleeve.
