Impure World Reincarnation
Naraku wiped his forehead with his sleeve and continued flipping through the Scroll of Sealing. As he looked down, the next Ninjutsu was called Impure World Reincarnation.
Following the guidance of the Scroll of Sealing, Naraku found the Impure World Reincarnation Ninjutsu in the cabinet. The Impure World Reincarnation scroll was as large as the Scroll of Sealing.
After opening the scroll, Naraku carefully examined the Impure World Reincarnation Jutsu. The Impure World Reincarnation technique contained a lot of information, and the Ninjutsu section was quite long. Naraku studied it word by word.
"Sacrifice, Earth Style a technique used in martial arts), souls, Cursed Seal, it's all so complicated..."
The Impure World Reincarnation is extremely complex, requiring the sacrifice of a living ninja to perform. The sacrifice must be a ninja with Chakra.
Generally, the strength of a ninja Impure World Reincarnation will be slightly different from that of their predecessor in life, but not drastically.
Of course, for some particularly powerful ninjas, special offerings might be needed to unleash the summoned ninja's full power.
"The Impure World Reincarnation Earth Style: Resurrection Technique Release: Reincarnation..."
Naraku observed for about half an hour, thoroughly studying the Impure World Reincarnation Technique and memorizing it. He also compared the Impure World Reincarnation with another reincarnation technique in his mind.
The two Earth Style Ninjutsu that the previous Guardian Ninja Kazuma possessed to manipulate corpses, Earth Style: Ultimate Creation Technique, which uses soil to envelop the dead and revive them, have a prerequisite: they require specially prepared corpse soil and environment to activate.
Earth Style: Resurrection Technique is more complex than the Ultimate Creation Technique. It involves covering the corpse with dust and using the power of Earth Style to completely revive it. The revived person's appearance, Ninjutsu abilities, and Chakra levels are all the same as before, and they are controlled by the caster.
The drawbacks of these two Earth Style: Resurrection Techniques are obvious: the corpse can only be resurrected once, and it is easily destroyed after resurrection. The body constructed of mud will disintegrate directly when hit by a heavy blow, and the soil containing the corpse requires a long time to prepare.
A more advanced Earth Style: Resurrection Technique is slightly better and more complex, and also requires a slightly longer preparation time, but it is also easier to control and more difficult to destroy.
These two reincarnation techniques are much simpler than the Impure World Reincarnation.
The body Impure World Reincarnation technique is constructed from mud and Cursed Seal. The source of Chakra requires a living ninja as a sacrifice, and the soul of the resurrected ninja is bound within the sacrifice for use. Furthermore, due to the Cursed Seal and other factors, the body is not easily destroyed and will continuously regenerate.
Another advantage of the Impure World Reincarnation is that the resurrected ninja has unlimited Chakra, endlessly drawing upon the Chakra and life force of the sacrificed ninja.
Theoretically, it's infinite Chakra, but it can't truly be infinite. The human body has great potential, which, in a sense, can be fully utilized and consumed by the resurrected person. A few high-intensity battles shouldn't cause problems, but whether it's truly infinite Chakra requires long-term experimentation.
"The Impure World Reincarnation requires a human sacrifice. Although Earth Style Release: Reincarnation violates ethics, it still wouldn't use a human sacrifice. This Ninjutsu completely reveals the Second Hokage's cruelty."
Naraku had little interest in practicing the Impure World Reincarnation. Naraku would not pursue this path of using living people for reincarnation and sacrifice unless absolutely necessary.
After memorizing the information about the Impure World Reincarnation, Naraku closed the scroll and set it aside.
Open the Scroll of Sealing and continue flipping through the scrolls. The next Ninjutsu section contains the ultimate Fuinjutsu, the S-rank Fuinjutsu, Dead Demon Consuming Seal.
Following the instructions in the Scroll of Sealing, Naraku found the scroll for the Dead Demon Consuming Seal from the Ninjutsu scrolls. Most S-rank Ninjutsu are one meter long and contain a lot of complex information.
Naraku opened the scroll of the Dead Demon Consuming Seal and studied it carefully. As a sealing master, Naraku had no blind spots in his understanding of this type of Fuinjutsu and quickly memorized the Dead Demon Consuming Seal.
"Sacrifice a soul... I still have a soul inside me. I'll see if I can exploit a bug to activate the Dead Demon Consuming Seal and sacrifice the Red Moon soul within me."
In Naraku's memories, Orochimaru had exploited a bug in the Shinigami's abilities. Not only did the Shinigami fail to harvest souls, but Orochimaru also released the souls it had devoured. This clearly proves that the Shinigami summoned by the Dead Demon Consuming Seal wasn't exactly clever.
Naraku closed the scroll of the Dead Demon Consuming Seal Ninjutsu, reviewed its contents in his mind, and after confirming that he hadn't forgotten anything or was unclear about anything, he put the Scroll of Sealing and the other Ninjutsu scrolls back into the cabinet as they had been arranged before.
The Scroll of Sealing is stored in a simple, unadorned place—a plain cabinet. It's easy to take; as long as you can fool the Konoha's strongest ninja, who is resting here, and the Anbu guards.
Naraku put down the Scroll of Sealing, went to his bedroom, washed up, and lay down on the bed.
"Ninjutsu that Konoha has submitted since the 51st year are in my possession. Tomorrow, I will spend some time compiling these Ninjutsu into the Scroll of Sealing."
Naraku planned to write Namikaze Minato's series of Ninjutsu, such as the Rasengan, as well as his training insights, in the Scroll of Sealing and store them as a reserve of Ninjutsu.
The Second Hokage developed many Ninjutsu for Konoha and entrusted them entirely to Konoha for safekeeping.
Naraku planned to write down his insights on the Ninjutsu Release: Lightning Release: Chidori series, Fire Style series, Taijutsu, Genjutsu as a contribution to the Fourth Hokage, to be stored in the Naruto Ninjutsu Library.
The Second Hokage's Flying Thunder God Technique and Impure World Reincarnation were mostly early versions, and were marked as forbidden to practice. Naraku also included the early version of the Chimera Technique as a forbidden technique, prohibiting all practice, and at the same time made a contribution.
Naraku could have already mastered most of the Ninjutsu on the Scroll of Sealing, although his method of understanding them wasn't through the most direct Ninjutsu scrolls. However, as the Hokage, Naraku could have requested them from ninjas who had mastered these Ninjutsu.
For example, Naraku asked Minato Namikaze for training Ninjutsu like the Flying Thunder God Namikaze Minato God Technique, but Naraku couldn't bring himself to do it. These Ninjutsu were all passed down from the Scroll of Sealing, and can be considered Ninjutsu from the Naruto Ninjutsu library.
If you want to comprehend it, you can just train in the Ninjutsu library yourself. Asking others for it is rather embarrassing and beneath you, so Naraku never mentioned such things.
However, Naraku has already collected most of the powerful Ninjutsu, such as the Rasengan, under the guise of leaving behind their legacy and being collected into the Scroll of Sealing.
Naraku pondered for a while the Ninjutsu he had just learned and comprehended, as well as the many secret missions he had assigned to Kazuma, Obito, Shisui, Orochimaru, Zensui, and others.
After pondering the progress of these matters, he focused on Danzo and Orochimaru, and then thought of Tsunade and his child at the mansion. He soon drifted off to sleep with a smile on his lips.
