I explained the body modification to Tsuyo before this occurred, I am not making it up just now. Also it is not anything different, by body modifications, again as I told Tsuyo, is just making someone immortal. You need to have been made into an immortal to use the Curse Blood Jutsu, hence it being hiden. I never claimed it was an additional thing.
Everyone is hearing about this just now because in nearly a decade there has never been an opposing Jashinist. I've never had to explain how the process works before, so I am now. I don't know how they can claim it's bs when no one ever bothered to ask before.
*ahem*
Bocchiere stole the experiments from the Cult of Jashin that he destroyed, only after destroying them he discovered that he could not replicate the experiment, thus I only have a limited amount of Jashinists I can make, due to the limited supply of chemicals that have proven impossible to reproduce. 10 to start now minus Night, Hazama, and Kuma. That's why I don't just make everyone in Akatsuki a Jashinist, there would be no downside to doing so otherwise.
Tsuyo did Human Path me, yes, but he also never made anyone a Jashinist in the time I was gone, then I came back and recovered my materials. Thus, though he has the knowledge, he does not have the means to make anyone immortal.
It is very hypocritical as in the same series of messages where he was denying my ability to state how the unstated facets of Jashinism work he was also citing Darkshinobi as proof for why something he was trying to do in regards to Hiraishin is legit. So Dark can say how Hiraishin works but I can't say how Jashinism works? Ok.
I explained all of this before, they just decided to ignore it and say they get to use the jutsu how they want anyway.
