The headphones were instantly filled with interference noise.

Forget about the reference signal tone, there isn't even a trace of a regular sound that humans can recognize.

There was nothing but pure, maddening, chaotic noise.

Wang Ai's face turned from pale to red, then to deathly pale, and her forehead was covered in cold sweat.

She frantically turned the knob, trying to find a usable signal.

But all she heard in her headphones was a jumble of interfering noise.

"Buzz buzz buzz...buzz buzz..." The loud noise from the amplifier was still raging in the laboratory, as if mocking her futile efforts.

Mingzhao stopped looking at her.

He picked up the output cable connected to his own crystal module and calmly plugged it into another input port on the same spare radio.

Then I pressed the power switch on my module.

Without making any unnecessary movements, she didn't even touch the tuning button.

Because that mineral module doesn't have a tuning knob at all.

Everyone in the laboratory had their eyes glued to the speaker of the spare radio.

Wang Ai also subconsciously stopped her futile twisting and looked up.

The piercing interference noise still raged in the power amplifier, but it was in this background noise that...

"Beep...beep beep...beep beep...beep..."

A clear, steady, and rhythmic electronic tone came through the speaker of the backup radio with perfect clarity.

This is the reference signal tone emitted by the signal generator.

Although somewhat faint due to the loud noise from the amplifier, its steady rhythm and clear tone shone like a lighthouse amidst the noise.

"Wow……"

The lab erupted in chaos.

The researchers who had been covering their ears lowered their hands in astonishment.

I looked incredulously at the radio that was emitting a clear signal.

Then he suddenly looked at the inconspicuous leak detection module on Mingzhao's desk, which was covered with ore and canned food skin.

"I heard it! I really heard it."

"My God! With such strong interference noise..."

"It's the baseline signal! That's right, this is the rhythm."

"That stone...is it really useful?"

Wang Ai stood frozen in place as if she had been struck by a spell, still clutching her communicator module in her hand.

His face was deathly pale, his lips trembled, and his eyes were fixed on Mingzhao's rudimentary device.

The anger, disdain, and judgment she had just displayed were now frozen and shattered on her face.

Then all that remained was pure, incomprehensible shock, and a hint of embarrassment at being publicly humiliated.

Su Xuan stood tall and proud, looking at the researchers who had come to laugh at him.

"What's going on? Who's making such a commotion here?"

A calm and authoritative voice rang out at the laboratory entrance.

The researchers blocking the lab entrance immediately stepped aside, automatically making way for them.

Zhang Mingyuan followed behind Director Wang, giving everyone a warning look.

Director Wang walked in quickly, his brows furrowed.

He spotted Engineer Wang standing frozen in place at a glance.

I also saw the strange-looking device on the table that emitted a clear signal, and I also saw Mingzhao's calm eyes.

The loud interference noise from the amplifier continued, but the beeping sound that pierced through the noise struck Director Wang's heart like a hammer.

Director Wang rushed to the table, his gaze sharp as lightning.

The light swept across Mingzhao's ore module, then across the completely missing communicator module in Zhang Gong's hand, and finally landed on the oscilloscope screen.

There, it is clearly shown that amidst the raging interference signals, the waveform representing the valid signal is being extracted and amplified by Mingzhao's module.

"Comrade Mingzhao."

Director Wang looked at Mingzhao, his voice trembling slightly with excitement, completely ignoring Wang Ai, whose face was pale beside him.

"This...this thing, you created it? Just now...this signal was received by it? Under such heavy interference."

The laboratory fell silent instantly, with only the continuous noise from the amplifier and the clear, steady beeping sound remaining.

Mingzhao met Director Wang's burning and eager gaze, and slowly nodded, her voice remaining calm.

"Director Wang, this is currently just a receiving verification module, which proves that the idea of ​​ore resonant filtering and antenna field focusing is feasible."

Mingzhao pointed to the simple device on the table: "It's still very crude. Its size, power consumption, and stability are far from sufficient, but the principle is sound."

Mingzhao's gaze swept across the faces in the laboratory, some shocked, some doubtful, and some excited.

Finally, he returned to Director Wang's face and spoke clearly, word by word.

"I am now reapplying to restart the communications team. Give me basic personnel and material support."

"I can make it into something that actually works."

Mingzhao's words were like a boulder thrown into a calm lake, stirring up a storm in everyone's hearts.

Su Xuan nodded with satisfaction. Mingzhao had finally learned to fight back and proactively request supplies from her superiors.

He would never have to spend his days picking up trash at the garbage dump with Mingzhao again.

In a corner of the laboratory, Wang Ai gripped her unresponsive module tightly, her knuckles turning white from the force and making a cracking sound.

The last trace of color drained from her face, leaving only a deathly, ashen look.

She looked at Director Wang's hand that was tightly gripping Mingzhao's shoulder, at the researchers' gazes towards Mingzhao that were initially filled with surprise and uncertainty, but gradually turned into awe, and even at Mingzhao's calm face...

A liquid carrying the metallic smell of rust seeped silently from between his tightly clenched fingers and dripped onto the cement floor of the laboratory.

That was blood drawn from her fingernails digging deep into her palm.

...

Su Xuan sat in the laboratory, sighing for a long time.

The laboratory miracle that shocked the entire institute seven days ago still resonates.

But the cold reality has already hit us hard.

Independent groups? Yes.

Personnel? For now, it's just Mingzhao and him.

Supplies? Director Wang's special approval note seemed so weak and powerless in the face of reality.

"Portable, reliable, anti-interference, and long-range." These four characteristics are now being combined into a palm-sized complete communicator, codenamed Tianyin.

Receiving is only the first step. Miniaturized power amplification, high-efficiency energy, and system integration at the transmitting end are all perilous peaks standing in the technological desert.

Su Xuan covered his face and scratched his head. He really couldn't imagine how to continue.

"Field-effect synergistic amplification...low voltage drive...high efficiency..."

“System integration…lightweight shell…” Here in the Federation, they use nanoscale composite materials, but on this planet, they use load-bearing metal shells and newly introduced engineering plastic samples that are still lying in the warehouse and controlled by Wang Ai.

"Su Xuan." Ming Zhao opened her eyes and looked at him. "How much of what's on the list can we get?"

Su Xuan walked to the cardboard box, took out the list, and frowned.

"I went to the new engineering plastics warehouse, but they said there were no quotas available and I have to wait for further notice... High-performance nickel-chromium batteries are strategic reserves; they only come with special approval from Engineer Wang. We're the ones who can get them..."

Su Xuan gave a wry smile and pointed to the corner, "You have a tattered sack."
