Let's get one major misconception cleared up before we go; I am not devil's advocate, but are we seriously trying to assert that the chakra network is not a physical system? That it is entirely spiritual?
That is impossible to claim, because the system, as I have pointed out in a by now long ago post, can be damaged by rasenshuriken. Now, correct me if i am wrong, but rasenshuriken cannot damage the soul of the target. By that logic, the chakra system is physical, even if only the physical energy gathering to mold with spiritual energy in da gut and then circulated out.
Yeah but if he doesn't then you don't,
that's how the jutsu works
No, Hidan's immortality not transferring to his victims is clear enough evidence against that claim.
Yeah this topic is very over now, I come out on top regardless.
If the chakra system is physical than it is turned to fire along with the rest of my body, and cannot suffer the melting damage done by the poison.
If the chakra system is not physical than damage done to it is not physical, and thus cannot be reflected via the Curse.
The only damage reflected at me will be needle stab marks, the poison melting my eyes, and the organ damage done to his body by destroying his own chakra system, all of which will be negated by my Incineration Technique.
So I guess we might say that, at the end of the day...
And as I believe that the chakra network is very much physical, to accept that you cannot be damaged, quite frankly, at all unless the flames are extinguished in some fashion would be stretching some belief.
This technique is said to work like the Hozuki technique, but this technique is certainly superior were this to go through. Why you might ask? Because presuming this blocks the damage, then the Hozuki should not be paralyzed by electricity flowing through them, as water itself is not affected by a current running through it; it merely lets it flow through it. Suigetsu, and every other Hozoki, would still have to have some sort of nervous system that could be affected in order for Raiton to paralyze rather than merely enhanced their water forms.
Therefore, their nervous system remains susceptible to damage and interruption if you can get the opposing force to "stick" in the water body. The Blood Controlling technique does not care what the opposing body is made of; it only cares that the affected portions are present in the victim's body, one heart for a heart kind of thing.
In my opinion, going fire mode would not save you from any and all damage done by this technique, if it would save you from any at all, especially if you were to argue that the chakra network is not physical. Because if it is not physical, then physical poison would not be able to affect it without consuming chakra itself, unless we were to assume that this metaphysical chakra network is made up of vessels made up of chakra, which would make the system absorbable by the Rinnegan ability.
That's my remaining cents on the issue, seeing as last night you guys apparently had a smoke or two to resolve this.
