Chapter 572 The Ancestor's New Function!

Just when Uncle Kim thought the situation was settled.

Now, let's turn our attention back to China.

The area around the bombed-out hill was a scene of bustling joy.

On a small earthen slope far from the planned dam, the cooks dug out a row of field stoves.

Each stove had a small iron pot on top, with flames roaring and steam rising.

The head cook even brandished a shovel, demonstrating his skills to the villagers of Jiangjia Village.

"Hehe, ancestor, look! This kind of stove I researched played a vital role on the northern battlefield!"

"This kind of stove doesn't produce much smoke. Back in the day, when the porters finally managed to bring up some white rice, I used this method to avoid the flies flying around..."

"Hey! Commander, wasn't that bowl of plain porridge I cooked back then delicious!"

"It smells so good...it's so good!"

The team leader offered a few insincere compliments while, following Jiang Dong's instructions, he opened the seasoning packet from the self-heating instant noodles and poured it into the large pot.

Then, he looked at Secretary Liu, who was eyeing him menacingly, and said, "Hey, comrade. We're all seasoned veterans, and our awareness is top-notch!"

"Didn't you see that all 63 guns were given to us for testing? We don't need to memorize so many regulations!"

"Heh, you tell me! Back then, the rumors were spreading like wildfire..." Secretary Liu squatted down next to Grandma Jiang, earnestly helping her pick out the thorn that had somehow gotten stuck in her hand.

Although the old lady kept saying it was fine, Secretary Liu had a stern look on her face and was even more careful in her selection.

"Hey! Commander! Forget it, it's just some stupid regulation, we'll just memorize it! But, even if we can memorize it, can you guarantee that Xiao Jiang will make a few big bombs for us?"

The hothead following the regimental commander was also furious at the sight of Secretary Liu.

Mother!

We've seen people who abuse their power, and we've already figured out a whole bunch of ways to deal with them!

"Ha, getting all high and mighty now! This is your duty, not a time for bargaining..."

"The big boss of the family hasn't arrived yet. Should we be firm and go down there?"

Secretary Liu wasn't going to tolerate these arrogant and unruly people, and was about to continue arguing back when Grandma spoke up.

"Alright, alright, give the old woman some face. How about you listen to me for a bit?"

Everyone fell silent.

Don't doubt it, the old lady just has this strange aura. Anyway, once she opens her mouth, everyone will listen to her quietly.

……

Not far from this group of people, the soldiers set up a tent.

Outside the tent, two diesel generators were roaring.

Inside the tent, two incandescent lamps hung in the small space. Beneath the lamps was a large wooden plank. Upon closer inspection, one would discover that supporting this plank were actually two large bronze cauldrons.

If Professor Sichen were here, he would definitely be giving people a lecture on how to protect antiques. But, that's not what everyone's attention is on right now.

He just stared blankly as Jiang Xia performed a series of operations in front of the wooden board.

Jiang Xia placed the large black box that Lao Wang had brought back from the Academy of Sciences on the wooden board.

I carefully opened the box and nodded in satisfaction at the sight of the several dark green boards in the center. Then, noticing the rosin and soldering iron tucked away in the corner, I was even happier.

The instructor standing next to Jiang Xia stared blankly at the board, puzzled: "Xiao Jiang, is this what you called the most important thing?"

"OK!"

Jiang Xia took out a board and examined it under the light.

Oh my goodness, look at these pins, look at these copper foil connections, they're so beautiful! They're starting to resemble the integrated circuit boards of later generations!

"What is this? Putting aside the pieces on it, it looks like a..."

The instructor hesitated for a moment, then nodded firmly: "It's like a large postage stamp!"

"Hey, you're right, but this is much more useful than a stamp!"

Do you know about Big Yellow's clones?

"I know! When the leader first came to you, wasn't it because he wanted to kidnap you and use you to exchange for a machine? Tsk tsk, it's really fast for sending messages!"

The instructor's slip of the tongue instantly caught the attention of Lao Wang and his men. In front of the unfriendly eyes of the old lai soldiers, a bead of sweat appeared on the instructor's forehead.

"Ha! Put these things together and you'll get the result you wanted! That way, you won't have to tie me up!"

Jiang Xia chuckled and waved his hand, interrupting Old Wang and his group who were continuously emitting death rays.

He pulled over a dark wooden board that "Big Guy" had picked up from the foot of the mountain, took out chalk from his bag, and started writing on it.

"Come on, instructor. Although I can assemble a usable thing for you right away, you still need to understand how it works. After all, you're going to such a far place, and it won't be easy to fix if it breaks."

"It is better to ask for others than to ask for yourself!"

Little Hairy Hair Classroom is in session again!

This thing, which is called a digital radio station, sounds sophisticated, but the principle behind it is actually not complicated at all.

It simply involves using a transistor modem to convert digital signals into analog signals suitable for wireless transmission (modulation), and to convert the received analog signals back into digital signals (demodulation).

Don't forget that Jiangxia's advanced version of the modem integrates Frequency Shift Keying (FSK) or Phase Shift Keying (PSK), making signal conversion a piece of cake!

Connecting the modem's output to the radio's audio input allows digital signals to be transmitted via the radio. For reception, the radio's audio output is connected to the modem's input to demodulate the signal.

Wouldn't that create a prototype of a usable digital radio station?

What? You're saying there's an important component missing?

Where do the original digital signals come from? How are analog signals converted back into digital signals?

Okay, that's a great question!

The problem that a tiny chip could solve in later generations would probably require a communications soldier to carry a clone of Big Yellow on his back to solve it today.

but……

Hehe, guess what those dark green, stamp-like things are?

Of course, it's the latest achievement of our female scientists at the Chinese Academy of Sciences—integrated circuits!

Now you understand, right?

Jiangxia's next step is to assemble these circuits into a single-board computer!

This single-board computer enables dedicated digital signal processing capabilities.

The Flying Line Technique is back!

However, before playing with the soldering iron, Jiang Xia washed his hands thoroughly and rubbed them on the bronze cauldron.

Well, don't think he's praying for the protection of his ancestors. The main reason is that the sweater he's wearing is a major source of static electricity.

When I took it off at night, it was like a burst of sparks, it looked amazing!

This is one of the reasons why Jiangxia specially brought the bronze tripod to place on the table.

"Hmm, ancestor, it also made a great contribution to eliminating static electricity. I'll make a note of it for you!"
