A nation's industrial development begins with junior engineers.

Chapter 841 The Jiang family possesses abilities that drive people crazy!

The air seemed to freeze at this moment.

Mulan's deliberately tense face froze instantly, her lips still curling into an angry downward smirk, but her eyes widened like copper bells, and she even forgot to retract her hands that were at her sides.

She could clearly hear her godfather's suppressed "huffing" behind her. Turning around, she saw the old general with his hands behind his back, his shoulders trembling, and even his graying temples shaking. He was clearly trying to hold back his laughter.

That silly kid... what's he thinking about all day long?!

Forced marriage?

Do your family know that you're doing this kind of thing at your age?

Mulan was both amused and exasperated. She reached out and gently tugged at Jiang Dong's pigtails. Jiang Dong shook his head as he was pulled, but he wasn't scared at all. Instead, he tiptoed closer and pulled out a handful of something that was yellowish-brown from his pocket.

"Eat?"

Mulan was also quite bold; she grabbed it, smelled it, and then put it in her mouth. Her uninhibited manner was quite to Jiang Dong's liking.

"It's just fried grasshoppers. I've roasted them before when I was a kid! But you're quite extravagant, frying them in oil..."

"Oh, you've done that too!"

"No, I roasted them over a fire. But where did you catch so many grasshoppers? I don't know if you burned them or what, they taste bitter. Do you have any more? Let me show you my cooking!"

"Okay, Auntie, no problem, Auntie!"

"Call sister!"

"Yes, dear sister..."

……

The story of these two is quite unusual.

If you're saying many people know about it, then yes, many do! But if you're saying no one knows...

The two parties involved in the incident were genuinely unaware of it.

However, these two siblings are indeed doing surprising things...

……

Laboratory of a traditional Chinese medicine factory in Northeast China.

"Jiang...Jiang, are you sure this will work?" The young girl from Cheng Gui looked incredulous: Are you trying to fool me because I can't understand mechanical drawings?

You talked about something so sophisticated and advanced, with automatic control and integrated systems, and after just one night, you're trying to fool us with this?

O man!

Indeed! The new blueprints Jiang Xia just showed me are quite beautifully drawn. But the annotations on the side are all about "old pipes," "scrap metal," and "pen nibs"—where is there even a trace of "high technology"?

"Of course it works!" Jiang Xia said smugly. Should I tell you that this is the best solution I arrived at after hundreds of simulations?

However, Cheng Gui, the young girl, didn't know where Jiang Xia's confidence came from, and still looked at Jiang Xia with a questioning gaze.

Just then, Factory Director Wang led several experienced fitters who had come to help into the laboratory. Seeing this, Jiang Xia simply picked up a piece of chalk and walked to the red brick wall of the laboratory.

"You've come at the perfect time. Time is short, so let's skip the pleasantries! I'll explain the renovation plan to everyone."

Jiang Xia took out the remaining half pack of cigarettes from his pocket and tossed it to Lao Wang, asking him to distribute it. This pack of cigarettes was left to him by Li Huaide two weeks ago when he returned to the machinery factory.

The little guy is now consciously starting to control his smoking habit; to use the scanner properly, you need to be in good health...

Seeing that everyone was sitting obediently, Jiang Xia nodded in satisfaction. "Teacher Jiang's Little Classroom, let's begin!"

He simply drew a simplified cross-sectional diagram of the tank on the red brick wall:

"We don't need to change the main body of this old 500-liter purification tank; the key is to modify two places... the bottom and the top of the tank."

The chalk scraped across the wall, making a crisp sound: "The original flat bottom needs to be cut off, and a 60-degree conical bottom needs to be welded on. The material will be scraps from the workshop's discarded reaction vessels; they're all stainless steel, acid and alkali resistant, a perfect match."

An experienced fitter, a cigarette dangling from his lips, squinted as he examined the pattern: "How do we handle the hole at the bottom of the cone?"

“Leave a discharge port at the very bottom of the cone and install a gate valve salvaged from an old water pump.” Jiang Xia drew a circle at the bottom of the cone. “Open a 15-centimeter diameter air inlet on the side and weld a sheet metal pipe to it. Hot air enters from here, causing the powder to ‘float’ in the tank, just like boiling water. This is the core principle of a ‘fluidized bed’.”

Production Manager Liu also felt that the design draft in front of him was quite different from what Jiang Xia had described yesterday, but that didn't stop him from quickly taking notes in his notebook and asking further questions:

"What about the top of the tank? How do you plan to implement that 'cyclone separator' you mentioned yesterday? Last time you said you wanted to 'separate fine powder,' you can't just cover it with a cloth bag, can you?"

"The cloth bag really does come in handy, but we need to weld a 'cyclone' on it first!"

Jiang Xia walked to his side and gestured with his arm to indicate the size: "Find a piece of old sheet metal that is 1.5 millimeters thick."

I saw a ventilation duct on the floor in our workshop yesterday; that will do. We can cut and weld a cone-shaped tube, 30 centimeters in diameter and 60 centimeters high.

A short pipe is welded to the top of the cylinder, and a coarse cotton bag is attached to it. An old steel pipe is welded to the bottom of the cylinder as a return pipe. The fine powder is carried up by the hot air, swirls inside the cylinder, and then settles down, flowing back into the tank for regranulation—not a single grain is wasted.

As she spoke, Jiang Xia looked at the fitter who had just asked the question: "Can this be made?"

"Small thing!"

Cheng Gui, the young girl, finally couldn't resist stepping forward and pointing to the "nozzle" mark on the drawing: "Engineer Jiang, your atomizing nozzle drawing is really well done..."

But why did you label it with a pen nib?

"Is the name of this nozzle 'pen tip,' or...?"

"Yes, just like you think! This is a pen nib!"

As he spoke, Jiang Xia took out a fountain pen that he had written on with a split shape and waved it in front of Cheng Gui's little girl!

what?

It really is a fountain pen nib!

Yesterday they were saying that this nozzle was processed using a laser emitter, how come it's become a genuine pen nib today?

Cheng Gui thought the person in front of her was really good at making empty promises!

Hmph, I should have made you memorize that thick "dictionary"!

The young girl from Chenggui, who felt she had been misled, is now filled with malice...

So, it's true what they say, birds of a feather flock together. Anyway, this Jiang family has a knack for driving people crazy.
