The techniques yielded by Project Monster Repellant were not really techniques as much as they were tactics and strategies. Furthermore, they were tactics and strategies that were exclusive to the Shionel Dungeon for the most part.
They were quite different from what Rui would normally attempt, but his circumstances demanded that he go beyond his comfort zone and develop a way to make his objective of being the first to clear the Shionel Dungeon more realistic.
In order to master the two techniques that were born from Project Monster Repellant, he needed to engage in a decent amount of training. He had already been dedicating quite some time to mastering the foundations of a sword identical to the ones that he would be commissioning.
On top of that, he had been subjecting himself to some light conditioning. Specifically, he wanted to grow completely comfortable with extremely hot air in his lungs. While he found out that his Martial body was durable enough such that even the more delicate tissue inside his respiratory system, it was still hot enough to cause a lot of discomfort and could cause burns or blisters over time.
Thus he had been conditioning his respiratory system to handle the heat without experiencing any issues to any degree. He had to ensure that he was ready rapidly fire his heated air Tempestuous Ripples, which he also needed to focus on adapting to the Apprentice Realm.
The project was coming along very well, he had already reached a stage where he was absolutely certain that the project would be a perfect success. There was no ounce of uncertainty in that regard.
However, the same could not be said for Project Eyespy.
He had more or less figured out the esoteric substances that he would be using to create the foundation for the technique.
Cryllin Stone and Grainer Pollen were two esoteric substances and compounds that individually lacked what he needed, but together, they could provide him with what he wanted as long as he applied them correctly.
Cryllin Stone was an esoteric substance whose temperature was entirely a product of gravitational field strength. The closer it was to the source of gravity, such as a body of matter or energy, the colder it would get.
Yet what ultimately made Rui go for this esoteric substance was the mathematical relation that was empirically observed to exist between temperature and the distances between the stone and the source of gravity.
It was observed through rigorous experimentation and observation that the temperature of the body was proportional to the fourth root of the distance between the Cryllin Stone and gravitational sources.
What that meant was that if the distance was increased by twice, then it would not grow twice as hot, it would grow sixteen times as how. If the distance was increased by thrice, then the temperature would grow eighty-one times as hot compared to before it moved.
It was precisely because of this radical relationship that Rui had decided to use it. The fact that it was so sensitive to even the slightest shift in position and would react drastically, made it extremely useful to Rui who needed sensitive data. He could rely on the clearly radical shifts in the temperature of the Cryllin Stone inside his body to understand the distance between him and some body/object that was obviously producing gravity.
However, while this told him the distance between him and his surrounding objects, it did not tell him what direction they were in. Without knowing what direction his surrounding objects were located, he could not pinpoint their locations, and thus could not form an image of his surroundings.
This was where Grainer Pollen came in. This esoteric moved away in the exact opposite direction of the direction of the gravitational pull caused by the curvature in space. This meant that he could obtain the directions he needed.
Together, he could find out both the direction and distance of the closest body or mass, and when applied to all directions, he would be able to picture his environment quite accurately.
The problem was that he needed to distribute the esoteric across his body in the right way, otherwise, it wouldn't work the way he wanted it to. What he was applying was a principle of triangulation and the Parallax Method, one that was frequently used in astronomy. Astronomers, when wanting to pinpoint the location of a celestial body, would record it with observatories from opposite sides of the planet. If the triangle formed between these two points and the celestial body was thin and sharp, then it could be concluded that the celestial body was very far away. If the triangle formed by these three was short and stout, then it could be concluded that the celestial body was closer.
He was effectively applying this principle with all of his environment, using the distribution of esoteric substances across his body.
It had taken him quite some time to design the distribution configuration of these esoteric substances. He couldn't just blindly dump them all across his body, that would take a longer time to master and the sensory input would be too much. He needed to find exactly the optimal amount to ensure that he can still make out all of his environment precisely and accurately without an excess of sensory input.
It had taken him two months, but finally, he had completed the blueprint for the procedure. He had completed sensory details of the positioning of the esoterics within the body, he had gotten Martial doctors to overlook the procedure and vet it to ensure that it would not impact his health or life in any way. That alone had required him to revisit the blueprint several times due to some health hazard or the other. This process had happened several times until he had finally created a satisfactory blueprint for the space-curvature sensory technique.
Now, all that was left was to undergo the procedure and begin training to master this new sense that he had given his body.
