Rui grinned as he finally found what he was looking for. Months had gone into scouring the database for the right kinds of esoteric substances, and suitable esoteric phenomena. It was unfortunate that he couldn't do non-combat-related tasks at super speed, such as research, which was why he needed a lot of time to finish all these tasks.
However, his effort had finally paid off.
[Lundenfire marble]
This was a substance that was known to be able to cause a shocking sensation to those who touched it when it came into contact with another piece of Lundenfire marble. It had been empirically verified to be the same kind of phenomenon as lightning when experiments confirmed that substances behaved similarly to this phenomenon as they did with lightning.
This could give Rui what he was looking for, it was the solution to Kane's issue.
Furthermore, that was not the only discovery that he made.
He had come across a technique that he had never known before, a technique that was foundational in the field of poison.
This technique allowed the user to permanently integrate a substance into their body without ever needing to replenish said substance. This was a highly advanced form of conditioning that made use of the special traits of the Martial Body.
The Martial Body was an evolved species relative to the human body, it was superior in almost all ways. One of them most certainly included the human body's mild tendency to be able to adapt to grow more resistant to things that hurt it through gradually increasing prolonged exposure to it.
There were humans on Earth who had become increasingly resistant and even immune to poison and venom after years of exposure to those substances. The body went through anatomical, and physiological adaptations that allowed it to resist them better, and perhaps even be able to integrate small portion of it into the body.
The Martial Body had elevated this to another level, because of the enhanced healing factor of the body, the body's ability to adapt to certain things became a lot better due to healed cells and tissue being able to deal with it better than before. The reason for this was because the cells that survived and healed would recover and heal, passing on their ability to survive and heal to the next generation of cells and tissue.
Thus, dangerous substances could be introduced into certain parts of the body, and the body was capable of adapting to it.
Furthermore, there existed ways to teach the body to ingest said substance to replenish it elsewhere into the body, or even produce the foreign substance in the body from scratch. The potential for this came from the appendix of the digestive system.
The appendix used to be an organ for breaking down structures and compounds that were particularly hard to break down.
The organ was now redundant in the human body due to major diet changes, causing the organ to have grown redundant.
However, during the evolution of the body into the Martial Body, the organ also evolved. It became possible to do things that weren't possible prior, such as teaching the body to produce or at least ingest and replenish certain substances into the body, things that it couldn't do before.
It involved a painful and long conditioning training technique that would eventually force the body to develop that capability in a manner similar to how it gained capabilities during the Squire evolution breakthrough process.
It was essentially a smaller and downscaled version of the Squire evolution breakthrough phase without the radiation and the hyper-accelerated healing process.
Rui realized that this was a technique that was not only relevant to Kane for when he introduced the Lundenfire Marble into his body but also to Rui as well as due to the substances that he had introduced into his body when creating the Riemannian Echo technique.
However, that was not all, after seeing how promising the results of his research were, he couldn't help but feel the desire to use them not just for Kane, but also to benefit himself.
In other words, he wanted to create his own technique incorporating these concepts in mind.
Furthermore, he already had the perfect kind of technique in mind.
('I did recall lamenting my lacking grappling and wrestling combat,') Rui recalled. ('This is a good opportunity to handle that issue.')
In fact, a simple image popped into his head when he began considering the concept of the technique. It was an exceedingly simple and straightforward application of the research that he had done and the kind of techniques that he wanted to create.
('The individuality is great. I did all of this research myself, so there is no question of originality, and I'm willing to bet that it is very unique too,') Rui mused. ('As for affinity… Well, it's not bad, though it's nothing special in that regard.')
That was fine. Not every technique could have a perfect affinity with his Martial Art as the ODA System and the Forestep technique. Regardless, it was a fine addition to his Martial Art and deepened his Martial Path nonetheless.
He still needed to iron out some details to make sure what he had in mind, it wasn't safe for him to just throttle forward at top speed.
For one, it was possible that the Lunden Marble was too toxic to be able to integrate into their Martial bodies, in which case, there was simply no question. The worst part was ascertaining this, it would require a bit more time as Rui would need to conduct some more research on the substance and its viability as the foundation for some Martial Art techniques.
He would need to borrow the research facilities of the institute to learn what he needed. Thankfully, he didn't require much time, a handful simple and straightforward experiments would tell him everything that he needed to in this regard.
('Once that's out of the way, we can finally get through what we came here for in the first place,')
