Soul and Body
Seal it up?
After Kabuto unleashed the Impure World Reincarnation Jutsu Fourth Shinobi World War, the souls of those sealed Ninja returned to the Pure Land.
This means that as long as Black Zetsu has enough DNA, bringing the dead back to life is a piece of cake.
Wouldn't all that work be for nothing? Eiji didn't want things to end this way.
He looked down at the gradually taking shape heads of Hashirama and Tobirama, and began to examine their current physical condition with his Six Eyes.
The Impure World Reincarnation requires a portion of the deceased's DNA as a medium to summon the deceased's soul from the Pure Land to the World of the Living, where it is then attached to Living Sacrifice.
But where does the DNA used as the medium for summoning go after the spell is cast?
Matter cannot be created out of thin air, nor can it disappear out of thin air.
Previously, in order to resist his "Kaku," Hashirama Senju bit his finger and used his blood to summon Rashomon.
The condition for channeling is that the Contractor's own blood is required.
It is highly likely that this DNA was dispersed and integrated into the Flesh and Blood of this body.
In other words, this body contains Hashirama Senju's DNA.
The Jujutsu Kaisen has discussed extensively the debate about the Body and Soul, specifically whether the body precedes the soul or vice versa.
The Mahito's theory is that the soul precedes the body, but the appearance of Toji Fushiguro has flawed his theory.
After all, Toji Fushiguro regained control of his body by using the strength of his physical body, and Suguru Geto also experienced a situation where his soul was dead, his brain was replaced, and he was choking himself with his own body.
Toji Fushiguro could do it, then there's no reason why Hashirama, whose physical strength is even greater, couldn't do it. Besides, Hashirama's soul is still Original; it's just being controlled by someone else.
Eiji believed that the Second could do the same thing.
Okay, enough with the theory, let's put it into practice.
Eiji placed his hands on Hashirama and Tobirama's heads respectively, and said in a deep voice, "I will make Binding Vow, in exchange for not being able to eat Kikufuku for the Future Fifty Years, to double the Recovery Efficiency of the Projection of Reverse Cursed Technique in the Future!"
With Eiji's current skill level, he can almost instantly repair missing limbs, but when Eiji uses the Reverse Cursed Technique to repair the body of others, the effect is halved.
We cannot give Black Zetsu time to react; we must act swiftly. Therefore, imposing Binding Vow to accelerate this process is necessary.
The price of such Binding Vow is clear in one's mind when deciding to establish Binding Vow.
Although this condition seems somewhat cheap, compared to the unreasonable Binding Vow in the original work, Eiji feels he has a clear conscience.
If we only consider the situation in the Hokage world, it definitely won't work.
However, Eiji is currently using Satoru Gojo's template, so what he does will naturally be integrated into the Jujutsu Kaisen mechanism.
From the moment he intended to use the Projection of Reverse Cursed Technique, the rules were absolutely on the side of the Jujutsu Kaisen; otherwise, the Projection of Reverse Cursed Technique would not have taken effect.
Now, a new problem arises.
When Eiji uses the Projection of Reverse Cursed Technique to heal this body, will it heal the body of the Living Sacrifice, or will it heal the body of Hashirama Senju?
Eiji bet on the latter.
The Reverse Cursed Technique heals the "Normal State" of this physical body according to the Cursed Technique's understanding.
But who defines the "Normal State"?
Defined by both soul and body.
The theory, of course, adopts the understanding of the world of Jujutsu Kaisen.
Living Person = body + soul.
Based on the conclusions drawn from previous Summoning Technique, there are now two different types of DNA in this body.
I. Hashirama Senju's DNA
II. The DNA of the Human Living Sacrifice
However, the second key element that makes up a "person," the soul, is 100% Hashirama Senju himself.
It's self-evident which is the foreign substance: Hashirama Senju's DNA or the DNA of the Living Sacrifice.
◇
With the continued effect of the Projection of Reverse Cursed Technique, Hashirama Senju and Tobirama Senju's bodies were restored at an unimaginable speed!
Bones, Flesh and Blood, and Organs began to grow wildly!
Orochimaru was dumbfounded by this astonishing scene. Was this really considered living?
Doesn't this mean Eiji has grasped the Truth of Immortality!?
"Eiji, you healed the dead!?"
Tsunade could tell that Eiji wanted to use Reverse Cursed Technique, but could heal the dead in this way?
"Well, it seems my theory was correct."
After finishing all this, Eiji wiped the sweat from his forehead. Luckily, he had set up Binding Vow to speed up his recovery; otherwise, it would have been troublesome if Black Zetsu had seized the opportunity to end the Impure World Reincarnation.
But now that I think about it, that guy was probably still in a daze.
After all, even Eiji himself considered it a Miracles that he could do something like that.
The Jujutsu Kaisen World usually can't bring the dead back to the World of the Living, but it can in the Hokage world.
This results in a wonderful chemical reaction when the two are combined.
After all, according to the theory of Jujutsu Kaisen, the Senju Brothers have both body and soul, so they can be considered alive and can also cast the Projection of Reverse Cursed Technique.
Eiji was delighted; he had discovered a way to replace Rinne Rebirth.
The reason why those Impure World Reincarnation experience no pain or taste is simply because the cells in their bodies no longer function, so naturally they cannot feel pain or taste.
Now, under the observation of the Six Eyes, both of their Organs are functioning normally, so Hashirama and Tobirama, who now possess their Original bodies, can experience the feeling of being alive.
"Impossible, how could something like that possibly succeed..."
Danzo at the scene before him, his pupils dilating in shock.
He watched as Hashirama Senju and Tobirama Senju stood up, and at that moment, color began to return to their faces, making them indistinguishable from Living Person!
"How could such a thing happen..."
Just as he predicted, he needed the Eyes of the Blue Sky to restore his physical body!
But now that Ryuuzaki Eiji has resurrected Hashirama and Tobirama with the Eyes of the Blue Sky, how should he plan to utilize this Supreme Dojutsu!?
◇
"How... how could this happen!?"
Because he wasn't present at the scene, all of Black Zetsu's information was relayed through White Zetsu, and only now is he belatedly realizing that something is wrong.
Just now, my connection with Hashirama and Tobirama was forcibly severed!
This indicates that the Impure World Reincarnation technique has been affected for some reason, but the specifics are still unclear.
Black Zetsu then attempted to dispel the Impure World Reincarnation Jutsu and re-enact the summoning, but all his efforts were in vain.
He then learned what had happened from White Zetsu. Black Zetsu, who was in the cave, slammed his fist on the Rock and gritted his teeth.
"That despicable Ryuuzaki Eiji, was this all part of your plan!?"
