- Do you practice organ transplantation? - It wasn't hard for me to guess what he was talking about. - I didn't know you were also interested in iryonin, Orochimaru-san.
I'm willing to bet that in an attempt to transplant the kekkai genkai, by transplanting the organs of a subject possessing it into a mere shinobi.
- It's hard to compare me to Tsunade-hime or you, Ryo-kun, but I've learned a few things in my life," the sannin shrugged his shoulders and looked up at me with an interested look, "I'm guessing you've had to deal with a similar situation yourself?
- Sooner or later, any experienced iryonin from the third degree and up faces such a situation - because it is the minimum requirement for such a complex operation - and either works by overkill, finding an organ that is not rejected by the patient's body, or understands the reasons for what is happening and he gets it right the first time," I enlightened the jonin, smiling a little proudly.
As a rule, for the vast majority of iryonins it's the first option, and only good sensors like me or really brilliant people get to the second.
- Oh, judging by these words, you managed to find out the reasons for rejection? - Orochimaru stepped forward with interest. - Would you like to share your experience?
- Why not? - I shrugged. - There are a few factors that influence the success of transplanting an organ from one person or animal to another: a common blood type, at least a partial elemental predisposition, and the absence of hostile elements between the donor and the patient, all other problems are solved by iryoninjutsu.
What's strangest of all, despite all the tools and techniques available for research, the local iryonins just haven't gotten around to separating blood into multiple groups. I suppose the presence of chakra, which is enough to make the dysfunctional work with great desire and skill, played a crucial role.
- Blood type? - The snake sannin frowned perplexedly.
- The blood of most people are different, but even in such a variety can be identified four groups, similar to each other - explained to him - and in each group, the blood of such a person can be transfused to another with minimal consequences, while a person from another group of such blood is no longer suitable and can cause negative reactions of the body.
It is not difficult to find out the regularities knowing about such information in advance, but it is hardly possible to come to such a conclusion without examination of tens of thousands of people and long experiments.
- Ryo-kun, did you figure out the pattern yourself? - Orochimaru raised his eyebrows, and something akin to respect appeared in his gaze.
- Thousands of shinobi and kunoichi have passed through my hands," I snorted, "I've had a chance to compare.
- How interesting, I never thought about such nuances," the snake sannin licked his lips and continued asking, "and how do you determine the chakra predisposition of unconscious patients?
- The usual paper for determining the predisposition, - I searched through my pockets and pulled out the sought-after, holding it out to the interlocutor, - add a small stamp of passive pulling of chakra and the question is solved.
