Chapter 790 Storm? Let's add some more low pressure!
Upon hearing the explosive news brought by Li Huaide, the atmosphere inside the armored vehicle instantly became tense. Chief Guard Cheng and Old Wang frowned almost simultaneously, exchanging a glance and both seeing deep vigilance in each other's eyes.
Jiang Xia reassured Li Huaide a few more times, urging him to stay with Director Yang, pay attention to his own safety, and notify him immediately if he had any news. Then he ended the call and got out of the car on his own.
As soon as the communication was interrupted, Chief Guard Cheng and Old Wang said almost in unison, "The radio! I'll use it first!"
Chief of Staff Cheng acted even faster, grabbing the communication headset from inside the armored vehicle in an attempt to contact his direct superior.
Old Wang was a bit slow, and frustratedly pounded his thigh. Knowing that he was in a different command order and couldn't beat Chief Guard Cheng, he took a deep breath, pushed open the door, and jumped out of the armored vehicle.
Outside the car, the morning air was cool, but it couldn't dispel the anxiety in Old Wang's heart. He looked at Jiang Xia in front of him, only to see that the kid was acting as if nothing had happened, happily joining Zhou Wenbin and his group of geological team members, pointing at the radar screen and continuing to explain, as if the phone call that could have triggered an earthquake had never happened.
Old Wang couldn't help but shake his head and sigh to himself: "This kid... is still too young! He has no idea what it means for the 'Logistics Department' to suddenly change personnel at a time like this! This is not a simple personnel transfer; it's clearly a knife to his throat!"
He had weathered many storms and knew all too well the dangers involved. This meant that the other side had not only detected their actions but had also launched a fierce counterattack at the highest levels, directly cutting off their potential channels of logistical support and legal recourse!
The next step could very well be for someone wielding a trivial authority to forcibly take over or even launch a counterattack!
Recalling certain old stories, "leading the way"? And ultimately stumbling... and the newspapers posted on the bulletin boards of Wudaokou and the universities of Beijing...
Old Wang's heart sank again, and a familiar, inexplicable feeling of suffocation washed over him once more.
But, considering what that silly kid did, it's not that bad, it's not that bad...
This kid has impeccable credentials; he wasn't born into a prominent family, nor did he have any overseas experience, and he has some unknown background. Those ambitious people wouldn't be so stupid as to want to mess with this precious guy.
At that moment, Jiang Xia, who was patiently instructing Zhou Wenbin, took in all of Lao Wang's reactions out of the corner of his eye.
Jiang Xia's faint smile deepened. He was well aware of the seriousness of the situation, but he was even more convinced that his people were not pushovers.
When the sky falls, there are always tall people to hold it up first. What he needs to do now is to stabilize the situation at hand and grasp the real gold and evidence.
Moreover, behind him were more than just a "tall guy".
Zhou Wenbin didn't know what had happened, but the tense atmosphere made this seemingly simple-minded but actually sensitive guy realize something. He looked at Jiang Xia and moved his lips.
"What's the panic?" Jiang Xia patted Zhou Wenbin on the shoulder, his voice soft but reassuring. "The sky hasn't fallen yet. Even if it did, we'd have to dig out the gold underneath first!"
“Come on, Engineer Zhou, don’t just stand there, let’s put it into practice. No matter how well you remember the theoretical knowledge, it’s not as good as experiencing it firsthand.” Jiang Xia pointed to the constantly scrolling and refreshing data on the digital tube, “Look, these undulating curves are the reflections of electromagnetic waves by different underground media. What we are looking for are those unusually strong reflectors, especially the areas where the dielectric constant is significantly high.”
Zhou Wenbin and several other geologists immediately gathered around, their eyes filled with curiosity. Even Old Li stroked his beard and leaned closer for a closer look.
“The key lies in these formulas,” Jiang Xia traced lines on the cold screen with his fingertip. “The propagation speed of electromagnetic waves in a medium is v = c / √(e_r), where c is the speed of light and e_r is the relative permittivity we want to deduce. Then, the depth d is determined by the two-way travel time t: d = (v * t) / 2. The radar emits radio frequency pulses and receives echoes. By analyzing the amplitude and travel time of the echoes, we can infer the shape and properties of the underground structure. Gold veins or veins rich in metal sulfides have a huge difference in conductivity and permittivity compared to the surrounding rocks, which will form a very bright, clearly hyperbolic anomalous signal.”
Zhou Wenbin twitched his lips, pointed to the string of coordinates and depth values displayed on the constantly changing digital tube, and couldn't help but interrupt Jiang Xia:
"No, Comrade Xiao Jiang, do you think I've forgotten what a hyperbola looks like in the textbook just because I spend all my time in the mountains? This thing of yours... it's all twisted and turned and numbers, at most it gives you a depth and intensity value, it doesn't look like a 'curve' at all! How am I supposed to read this?"
As he spoke, his voice gradually faded. He looked at Jiang Xia, who was smiling and completely unconcerned, and then at the constantly updating numbers. Suddenly, it dawned on him, and he slapped his forehead:
"That's it! My stubborn mind! You converted these real-time numbers directly into images in your head and drew that 'hyperbola'?! My God... how fast must your mental arithmetic be?"
Jiang Xia, still smiling, explained, "Engineer Zhou, don't treat me like a monster. Actually, this machine is also equipped with a paper tape recorder, which can automatically print out continuous waveforms, and you can see a standard hyperbola on them. What I really meant was this..."
He pointed to a component on the side of the control panel that was slowly clicking, a roll of paper tape being slowly ejected at a steady pace, displaying continuous but slightly lagging analog waveforms.
“However,” Jiang Xia pointed to the control panel, “in order to ensure the priority of real-time data processing and display, most of the computing power is allocated to the core parsing unit at the front end, so the speed of this paper tape drawing is much slower. Consider it as leaving a hard copy for archiving. If you really need to make a judgment immediately, you still have to rely on looking at this pile of ‘twisting numbers’.”
"Come on, forget about curves or numbers, the anomaly will speak for itself. Let's increase the gain a bit more and focus on the shallow to mid-levels..."
As he explained, he operated the radar to scan the surrounding area. The armored vehicle was parked beside the fork in the road at the entrance to the ravine.
The waveform on the radar screen was originally a relatively smooth undulation, corresponding to common soil layers and bedrock. Jiang Xia slowly adjusted the direction of the antenna and the detection depth.
“Look closely, now we’re turning up the gain and focusing on the shallow to mid-layers…” Jiang Xia said, rotating a few knobs at a steady pace.
The numbers on the digital tube began to jump and refresh at an unprecedented frequency, and the value representing the signal strength suddenly soared to an astonishing level!
"what?"
Jiang Xia stared at the rapidly spinning numbers on the digital tube, his hands flying across the open notebook as he sketched out the data based on the real-time flow.
The pencil scratches across the paper, making a soft rustling sound, and quickly forms a series of extremely steep, clear, and perfect hyperbolic signals!
"Mr. Li, come and see this!" Jiang Xia handed over the notebook.
Old Li shoved Zhou Wenbin, who was still standing there stunned, snatched the notebook, adjusted his reading glasses, and gasped at the sight of it. His finger trembled as he pointed at the curves:
"Hiss—! This, this shape! This convergence! A typical response of a high-resistivity, high-reflectivity body! Look at the steepness of the curve and the intensity of the amplitude. It's definitely not sporadic contamination. This is a characteristic display of a dense, massive sulfide enrichment zone! The pyrite mineralization and arsenopyrite formation must be extremely strong!"
The occurrence state of gold is often closely related to these sulfides!
Look at these estimated volume resistivity and dielectric constant, they're astonishingly high! The scale, the depth of burial…”
"Wenbin, quickly bring out your drawing and compare it..."
Just then, the paper tape recorder on the next table seemed to have finally finished processing the data and began to operate slowly with a "squeaking" sound, drawing simulated waveforms on the paper tape at a leisurely pace.
The hyperbola shape that appeared on it was almost identical to the one that Jiang Xia had already drawn freehand on the paper, only it was several minutes late.
Zhou Wenbin glanced at the slowly forming curve on the paper tape, then abruptly turned to look at the already completed hand-drawn sketch in Jiang Xia's notebook. His gaze finally settled on Jiang Xia's relaxed expression, as if she had merely sketched a flower casually. He twitched his lips and couldn't help but mutter:
"Jiang Gong...you...you still say you're not a 'superman'?! We're waiting for the machine to spit out the paper tape, and you've already finished the whole process of mental arithmetic and hand-drawing?! This isn't 'a piece of cake,' you've got superhuman abilities!"
