This thing was much larger than a handheld electronic thermometer, standing on the ground like a small cannon.
"We've established a concept of spiritual level value..." Zhou Miaomiao explained, "It's essentially a measurement of the disorder of electronic motion."
"In an environment devoid of spiritual energy, where all electrons move in an orderly fashion, the spiritual level value would be 0."
"Using this as a baseline, we can roughly determine the spiritual level values of various spiritual lands and even different cultivators."
It indeed resembled a thermometer.
If temperature is a macroscopic reflection of the random motion of particles, then the spiritual level value is a macroscopic representation of the chaotic interference of spiritual energy.
"Is this... accurate? How does it compare to the Spirit Eye Technique?"
"We've only measured a few researchers who have just begun their cultivation..." Zhou Miaomiao seemed hesitant to make any guarantees. "If we set the average spiritual level for a fully realized Qi Refinement Stage One at 10..."
"Then Qi Refinement Stage Two would probably be between 10 and 20."
"We tested Teacher Tian's spiritual level; she's at Qi Refinement Stage Eight, and her value is in the seventies."
Similar technologies existed in the Xuanwei Realm, but the main issue was precision.
After pondering for a moment, he sent a message to Bai Laotou and Tang Lingwu, asking them to come over.
"What's up?"
Bai Laotou and the others hurried over, thinking something important had happened.
"Come on, Professor Bai, you try it first."
Bai Laotou stood in front of the spiritual energy measuring device like a little guinea pig.
Zhou Miaomiao pressed a button on the side of the scanner, and a number appeared on the electronic screen.
"140."
Zhou Miaomiao was stunned, exclaiming, "Professor Bai, have you broken through to Foundation Establishment?"
Zheng Fa understood her surprise. According to her, Bai Laotou, at Qi Refinement Stage Eight, shouldn't exceed eighty.
"Professor Tang, how about you give it a try?"
Zheng Fa didn't say much but turned to Tang Mu.
Tang Mu looked quite interested and stepped up to measure.
"62."
Now that seemed normal.
This meant that the measurements for both Tang Mu and Teacher Tian were quite accurate.
Both of them cultivated at a decent pace, especially Tang Mu, who had a strong family background and perhaps a better understanding of the classics than Zheng Fa.
Now, one was at Qi Refinement Stage Seven and the other at Stage Eight, both in the late stages of Qi Refinement.
It's worth noting that Bai Laotou was only at Qi Refinement Stage Eight.
Aside from Bai Laotou's slightly inferior aptitude, it might also be that this old man was particularly fond of the "Five Thunder Law Body" (Wu Lei Fa Ti)…
Zheng Fa paused for a moment, suddenly realizing:
"Is it because of the 'Five Thunder Law Body'?"
"Exactly!"
Tang Mu clapped his hands, "The 'Five Thunder Law Body' is a thunder-based law body, so it's understandable that it has a greater impact on electrons, which is why Old Bai's value is double that of a normal person..."
"You're the one who's not normal!"
Bai Laotou retorted, crossing his arms and looking quite pleased with himself.
But Zheng Fa had another surprise.
This was getting interesting...
Bai Laotou's value indicated that this spiritual energy measuring device was not only measuring the spiritual power within cultivators but could also, to some extent, discern their law body—or rather, their combat power!
For Bai Laotou, although he was usually suppressed by Teacher Tian with just a glance, if it came down to it, after mastering the "Five Thunder Law Body," he could probably take on Teacher Tian without much trouble.
Meanwhile, Lingwu, who had been hiding away to cultivate, was now eyeing the spiritual energy measuring device with eager anticipation.
"Lingwu, why don't you check your spiritual level value?"
Bai Laotou said with a smile, his gaze towards Tang Lingwu filled with affection, as if he thought this little one had been too pent-up lately and wanted her to have some fun.
Of course, there was also a hint of curiosity.
In the nursing home, aside from Zheng Fa, who was at the Golden Core stage, the highest cultivation level was Tang Lingwu at Foundation Establishment.
Tang Lingwu nodded and stood gracefully in front of the device.
"13368."
Everyone was stunned into silence.
Bai Laotou's back inexplicably hunched over.
What were two Teacher Tians compared to this?
Little Lingwu could take on a hundred of herself!
Zheng Fa, however, nodded inwardly.
This indicated that the device was indeed quite accurate.
In the Xuanwei Realm, the major realms from Qi Refinement to Foundation Establishment represented nearly a hundredfold increase.
Because of this vast gap, many cultivators would spend their entire lives struggling at the Foundation Establishment threshold.
What pleased him was that, through the "洞虚灵眼" (Dong Xu Ling Yan), Zheng Fa could only obtain qualitative data.
He could see that Tang Lingwu's spiritual power was many times greater than Bai Laotou's.
But how many times exactly was hard to quantify.
Yet this spiritual energy scanner seemed capable of doing just that!
Suddenly, Zheng Fa thought of numerous applications for this spiritual energy scanner—
Measuring the strength of various techniques to create more potent methods of cultivating spiritual power.
During drug experiments, it could be used to assess the efficacy of various spiritual herbs.
Even in this mining research, it could be helpful—measuring the concentration of spiritual energy in the land could, to some extent, reveal the location of minerals!
One could say... this spiritual energy scanner was the starting point for data-driven cultivation!
As he was lost in thought, Bai Laotou's cheerful voice broke through, "Lingwu, how are you so amazing!"
The old man's eyes sparkled with envy.
Tang Lingwu seemed a bit shy, breaking into a smile.
But unbeknownst to her, the pressure in her brow had lessened considerably.
Zhou Miaomiao looked at Zheng Fa, seemingly waiting for him to measure himself, but Zheng Fa glanced at Tang Lingwu and ignored the expectation in Zhou Miaomiao's eyes.
He understood that not only was he a Golden Core cultivator unlike any other, but he also had the Fusang Wood (Fusang Mu) within him.
If the machine was inaccurate, that would be fine.
But if it was accurate...
He feared Tang Lingwu wouldn't be able to handle it.
Unexpectedly, Tang Lingwu suddenly looked at him, her eyes filled with determination. She reached out, took his hand, and gently pulled him to the device, nodding at Zhou Miaomiao.
"*****"
The display screen of the device showed a series of asterisks...
"This..."
Everyone stared blankly at Zhou Miaomiao.
Zhou Miaomiao scratched her head, checking for a long time before looking up in shock:
"It exceeded the maximum value."
Bai Laotou's eyes widened, "It broke the scale?"
Zhou Miaomiao nodded.
Tang Mu, curious, asked, "What's the highest value you have?"
"One hundred million," Zhou Miaomiao said helplessly, "Once it exceeds this value, the electron motion becomes too chaotic."
Bai Laotou frowned, muttering, "The limit for Qi Refinement is one hundred, and Golden Cores exceed one hundred million? That's quite a leap!"
But Tang Lingwu seemed to have anticipated this:
"Not necessarily; Zheng Fa's Golden Core is already stronger than average."
"Moreover, he possesses the Fusang Wood, which is even more powerful than the 'Five Thunder Law Body.'"
She then asked, "What's the spiritual energy concentration of Hongshan?"
"When the 'Ling Mountain Law' is in operation, the average spiritual energy concentration is around one million."
Zheng Fa was quietly calculating.
If he compared the current spiritual energy concentration of Hongshan with that of the Xuanwei Realm, it would mean that Hongshan was essentially equivalent to a Golden Core sect's spiritual vein, indicating that nurturing Golden Core cultivators wouldn't be a problem.
However, for Nascent Soul cultivators, they would need to rely on spiritual herbs and such.
Tang Lingwu made a valid point... Hongshan's spiritual energy concentration was still due to her own spiritual power being denser than that of an average Golden Core.
But the main reason for the device breaking the scale wasn't just that... it was the Fusang Wood!
The Fusang Wood is a spiritual root of Dao fruit level, containing spiritual energy that should not be underestimated.
Even though the spiritual energy concentration outside Hongshan was only a fraction of that within, the external space was vastly larger by billions of times.
The Fusang Wood could generate so much spiritual energy that it naturally raised Zheng Fa's spiritual level value by an immeasurable amount.
Perhaps Zheng Fa didn't have that much spiritual energy within him, but with the Fusang Wood present, it was hard for the spiritual energy scanner not to break the scale.
Zheng Fa shook his head, saying:
"The data is too sparse to draw conclusions, but this device should work well for measuring cultivators below the Golden Core stage."
"This thing is very useful for the nursing home! Zhou Miaomiao... I've already spoken to Team Leader Yang about your doctoral degree... with your contributions, you can also exchange for some techniques in the institute..."
Zhou Miaomiao fidgeted for a while before quietly asking, "Director, are there any elixirs?"
"Huh?" Zheng Fa was taken aback, remembering that this girl originally wanted to research spiritual herbs.
He glanced at Tang Lingwu, thought for a moment, and then turned to Zhou Miaomiao, "There might not be any right now, but the nursing home will definitely invest resources in research in the future. You can save your contribution points for now..."
He had already decided that after secretly learning alchemy from the Qingmu Sect, he would bring it back to the nursing home for research.
Otherwise, this little one, Tang Lingwu, would drive herself crazy.
