Chapter 325 (1/2)
Edo Tensei
After gathering enough living sacrifice, Ren Tianyou used kamui and arrived on an isolated island in the middle of the ocean, and began the preparation of Edo Tensei.
As stated before, this Edo Tensei was the forbidden summoning jutsu developed by Second Hokage Senju Tobirama. This jutsu could summon the soul of deceased person back to the living world and resurrect them by binding it to the living person. Afterwards this jutsu was improved by Orochimaru, and Kabuto brought it to the greatest height of development, but this jutsu however had three necessary prerequisites. They were:
First of all, the DNA of the person to be resurrected was required. If this condition wasn't be satisfied, then there was no way to resurrect; (i.e. a piece of human body of intended reincarnated was absolute necessity)
Afterwards a living person was required to use as a sacrifice to become the vessel of the intended reincarnated.
The soul of the intended reincarnated must reside in the Pure Land; if the soul was sealed, then it couldn't be summoned.
After this jutsu is used, the dust and ash would encase the body of the sacrifice, giving them the same appearance as the reincarnated had before the time of their death;
In Edo Tensei, although the jutsu user could restrain their movements, but the soul of reincarnated people could still free themselves if they were greatly stimulated in some emotional way. To prevent this from happening, the jutsu user could implant their control talisman in their brain, and completely wipe out the reincarnated soul's personality, making them have no sense of self, and turning into merely a killing tool. But like this, although the control over the reincarnated soul would strengthen, but they would be less resourceful and they required the attention of summoner for every action, reducing their strength.
Furthermore, those person reincarnated with the use of Edo Tensei couldn't be killed with any method, in other words, they obtain immortal body.
As far as the understanding of Ren Tianyou, there were only few ways to end this Edo Tensei jutsu!
The jutsu caster himself end the technique (on his own accord or forced). This is the most fundamental way to end this jutsu.
Sealing the body of reincarnated soul. This can only stop the action of reincarnated soul, but the Edo Tensei jutsu in itself will not end.
Remove the soul from the reincarnated body and seal it (such as with s.h.i.+ki Fujin (Sealing Jutsu—-Reaper Death Seal)). Then the Edo Tensei jutsu will automatically end. And after the soul itself is sealed, Edo Tensei will not be able to resurrect them again. Such the first hokage, second hokage and so on.
If the resurrected person still retains their personality, and had will that is sufficiently strong, then the soul might be able to struggle free from the binding and ascend to heaven. After that the Elo Tensei jutsu will automatically end. Such as Sasori.
Seize the control from the jutsu caster (only know method is Kotoamatsukami (Distinguished Heavenly G.o.ds), but the Edo Tensei jutsu in itself isn't ended, and summoning contract still exist. Such as Uchiha Itachi.
If the reincarnated person knows required hand seals of the Edo Tensei jutsu, then they could completely free themselves from the influence of Edo Tensei as well as free themselves from the summoning contract of Edo Tensei. Afterwards, they would be no longer under the control of jutsu user. Such Uchiha Madara.
Thoroughly destroy the physical body of reincarnated soul (only Yin-Yang style could accomplish it), but what would happen to soul, he didn't know.
If the resurrected deceased person is truly revived (only Rinnegan's Rinne Rebirth Jutsu can accomplish this), then Edo Tensei Jutsu would naturally end.
Moreover this Edo Tensei also had a small flaw, and that was, no matter how much skilled one was in this technique, there was no way to way to make the strength of the reincarnated person achieve their peak strength before their death, can only reach infinitely close!
Furthermore if the gap between the strength of the reincarnated person and the jutsu user was too big, then the jutsu user might not be able to control the reincarnated person, and get himself killed by the reincarnated person. But now Ren Tianyou had already refined the power of Forever Green completely, so his binding power would naturally be very strong, as a result, these reincarnated person would not be able to easily struggle free from his binding.
Standing on a mountain peak, the sharingan of Ren Tianyou spun rapidly. Then along with the appearance of spiral shaped s.p.a.ce ripple, two human figures appeared in front of Ren Tianyou.
Two middle-aged man with ferocious looking face and wearing cotton clothes knelt on the ground in front of Ren Tianyou. Right now their hands were tied behind them, and theirs eyes didn't have any spirit.
These living sacrifices, from the time they were sucked into the kamui s.p.a.ce, they had been under the illusion of Ren Tianyou, so there was no resistance.
