On the evening of the seventh day.

In the center of the warehouse, on a makeshift sheet of foam covered in solder and burn marks, a strange-looking receiver module lay quietly.

It is three-quarters smaller than the original communicator's receiver board, and the core part is no longer densely packed transistor circuits.

Instead, it was a coil made of crude copper wire, with a polished dark brown ore fixed in the center of the coil.

A few transistors, resistors, and capacitors were soldered to the side to form an extremely simple amplifier circuit.

Next to it is a geometrically shaped metal sheet cut, folded, and welded from tinplate. That is a folded dipole antenna modified by Mingzhao based on the concept of focusing interstellar energy fields.

Mingzhao carefully connected the output of the module to the oscilloscope, while the input was connected to his homemade signal generator that could produce interference at a specific frequency.

The oscilloscope screen lit up, and the sine wave, representing a pure signal, was immediately drowned out by noise, representing a strong interference signal.

This is precisely the most fatal flaw of current communication devices in actual combat.

Mingzhao held his breath, his fingers trembling slightly, as he connected the ore coil module to the signal path.

A miracle has happened!

The rampant noise on the screen seemed to be held down by an invisible hand!

Although it was not completely eliminated, its magnitude was significantly compressed and suppressed.

The waveform representing the valid signal has stubbornly emerged from the quagmire of clutter and become clearly discernible.

The originally piercing and sharp noise from the small, equally dilapidated speaker next to the receiver module, which also served as a terminal, suddenly decreased by a level.

It was a success!

Su Xuan was speechless with shock!

Although it was just a receiver module, and it was still very rudimentary, it did indeed capture that weak but clear and effective signal even in the context of strong interference.

Right at this moment.

With a "bang..." sound.

The laboratory door was flung open from the outside.

A tremendous sound echoed through the empty laboratory, and dust fell softly from the beams.

Wang Ai, with a gloomy face, rushed in first.

Behind him followed several newlyweds, including warehouse manager Xiao Liu, and a few researchers who came to see what was going on.

The entrance to Mingzhao's laboratory was instantly blocked by a huge crowd.

Wang Ai's gaze was like a poisoned knife, instantly fixing on Ming Zhao and the strange-looking device on his desk.

"Comrade Mingzhao!"

Wang Ai's voice was filled with undisguised anger and disdain, "You hid here for seven days and all you came up with was this? Playing tricks! Playing with stones? Flipping coins? And using a broken tin can as an antenna?"

Do you think this is some kind of shamanistic altar?

She rushed to the table, pointed at the ore recycling module, and spat almost onto Mingzhao's face.

"Look! Look at this! This is her so-called remedial plan. Not only is it a waste of the components allocated by the state, but now she's even resorting to feudal superstition. Can ore receive signals? It's utterly ridiculous."

"I think you've completely gone mad! You're insane!!"

The laboratory was deathly silent, except for Wang Ai's angry roars echoing through the room.

The researchers, who were watching the spectacle, looked at the rudimentary, almost laughable device on the table, and then at Ming Chao's pale, tired, yet unusually calm face. Their eyes were filled with doubt, pity, and even a hint of mockery.

“Engineer Wang, I respect you as a senior, but barging into someone else’s project lab with a group of people like this is not in accordance with regulations.”

Su Xuan said angrily to Wang Ai, his eyes filled with accusation as he looked at the others.

"Why not? We came to check on Comrade Mingzhao because we were concerned about his progress. After all, he hasn't been anywhere else for seven days. What if something happens to Comrade Mingzhao because he's rushing to meet the deadline?"

Wang Ai's words sounded good, and even those behind him who were watching the spectacle nodded in agreement.

That's right, that's what they think.

Su Xuan stood in front of Ming Zhao: "Fine, since that's what you all say, then I'll go ask Dean Zhang whether it's permissible for you to suddenly barge into someone else's lab and interfere with their experimental progress."

"Don't give me any favors. Have you already completed your own experiments? Or are you simply unable to do them and that's why you're checking on other people's progress?"

"Does disrupting other people's progress make you feel good about it?"

"Do they really have no sense of national or collective honor?"

"This thing is still in a rudimentary stage, but once it is successfully developed, its impact on society and the country will be groundbreaking."

Su Xuan's eyes swept over each of their faces: "I'm just asking you, are you capable of shouldering this responsibility?"

Trying to label them? Wang Aike wasn't buying it.

He suddenly grabbed the original receiver module of the communicator from the table.

He then pointed to Mingzhao's ore module, his voice rising, filled with a sense of judgment.

"He's hiding here, playing tricks, wasting national resources, and shirking his responsibilities!"

"Just wait, this time no one can save you! Pack your bags and get out of here. Sending you to the logistics department to feed the pigs is the least of your worries. I'm going to report this to the organization and deal with you seriously..."

"Engineer Wang."

Mingzhao suddenly spoke.

Her voice was not loud, even a little hoarse, but it was like a piece of ice thrown into boiling oil, strangely overpowering Engineer Wang's roar.

Su Xuan also quieted down, and everyone's eyes were focused on her.

Mingzhao raised her eyes, which were bloodshot from staying up all night. But now they were as calm as a deep pool.
