The Riemannian Echo was a technique to sense gravity that he had created by inserting esoteric substances that were sensitive to gravity and reacted in specific ways to gravity. He inserted them deep into his body so that he would effectively be able to treat them as sense organs inside his body capable of sensing warps in space-time.
That didn’t mean that the esoteric substances merged with the cells of his body, or became connected to his nervous system like other sense organs did. No.
It meant that he could sense their reactions to gravity inside his body and thus deduce the curvature of space based on that.
Right now, he was in a bit of a similar situation.
ραΠdαsΝοvεl ƈοm Just like back then, he was definitely unable to sense what he needed to. Considering that he overcame the problem with gravity, there was a chance that he could use the same solution to overcome that problem with the electromagnetic field.
If he inserted materials in his body that allowed him to sense the electromagnetic field, then maybe he could give himself the ability to sense the electromagnetic field.
However, there were issues with this solution as well. For one, he needed to do a lot of research into esoteric material science, just like he did back when he was working on the Riemannian Echo technique.
Unfortunately, that was not possible. The Thundering Valley was in the Fenescin Region, a rather remote region with very little going on. It meant that he would have to go pretty far before he reached a place that possessed the information that he needed. Then he would have to spend quite some time researching, looking for materials that reacted to the electromagnetic field.
Then he would also need to conduct some experiments.
It was simply too impractical an option at the moment. Had he been in the Kandrian Empire, it wouldn’t be an issue, but it was quite problematic in his current circumstances. Even if he did find a place that had such information, it would not be enough, after all, acquiring them would still cost him.
On top of all these practical issues, he also needed to be wary about getting comfortable inserting foreign substances into his body. He couldn’t just apply that solution each time. There were not only toxicity concerns that he wouldn’t be able to address in these circumstances, but also that there was a limit to the number of substances that he could keep track of inside his body. He couldn’t keep track of too many esoteric substances inside his body, they would simply be distracting beyond a certain point.
(‘For now, this isn’t a solution I can apply at this moment,’) He shook his head as his thoughts flew back to other options and considerations.
These weren’t the only ways in which he could sense the upward positively charged stream of particles.
Since they’re a dense stream of particles, it may be possible for me to sense them with Tempestuous Feel.
He had never particularly tried sensing them since he was always focused in the opposite direction; upwards towards the sky.

If he could sense the upwards drafts of the streamer with Tempestuous Feel, then he would be able to pinpoint the destination of a lightning bolt. As for whether it was possible, he would need to test it.
It was possible that Riemannian Echo when focused on the land might be able to pick on the incoming lightning bolts.
He was eager to try both of them.
He got up, leaving Kane a bit behind as he headed closer toward the entrance of the Thundering Valley.
“Wait,” Kane interjected. “Don’t tell me you plan to go again.”
“No,” Rui replied as he closed his eyes.
First, he used Tempestuous Feel to sense the land. While he was it, he tried using Seismic Mapping.
He wasn’t sure, but it was worth testing to see what the effects of using Seismic Mapping were. It was possible that the streams of positively charged particles leaving the ground would leave behind some seismic radiation that he could then use to identify them
BOOM BOOM BOOM!
“Tsk,” He tutted in irritation.
The seismic radiation from the lightning strikes was too loud, they completely overshadowed any seismic radiation that the positively charged stream might leave behind.
Tempestuous Feel was in a similar pickle, it was too difficult to make out any individual stream of particles. The reason for this was because the entirety of the Thundering Valley was a furnace for the atmosphere in a sense, the sheer amount of energy in the air meant that the particles were extremely excited, blasting into each other. Had it been in an ordinary environment, perhaps his senses would have been able to sense the stream, but unfortunately these circumstances made it too difficult.
(‘Let’s hope this works,’) He prayed as he used Riemannian Echo to scan the valley.
The Riemannian Echo technique was never one to distinguish detail, unfortunately. He was able to sense streams of energy muffled across the entire valley, but he couldn’t pinpoint their location. He was unable to sacrifice scale for detail. He could only choose which direction he directed the scale of his senses.
The preliminary experiments with all three sensory techniques failed. He didn’t even bother using Primordial Instinct since it only detected threats within things that Rui could already sense.
Just before he was about to consider other possibilities, a simple idea plopped into his mind.
(‘What if I compare data from all three senses simultaneously?’) Rui wondered.
Focusing on the feed of the three sensory techniques was mentally taxing though Rui was confident he could deal with it just fine as long as he didn’t spend too much time on it.
It was no different from normal humans trying to pay attention to their vision, hearing, and sense of touch at the same time. It was extremely tricky and difficult, but not impossible as long as one was sharp.
Rui had a feeling that something might go different this time.
