A nation's industrial development begins with junior engineers.

Upon arriving at the office, the badge-wearing soldier guarding the door grinned at Jiang Xia.

"Good morning, Engineer Jiang!"

"Good morning, have you had breakfast yet?"

Seeing the badge warrior smile but not reply, Jiang Xia took out a flatbread and a small oil paper packet, "Soak it in boiling water for three minutes and taste it. Don't worry, Old Wang paid for it..."

As I entered the office, brushing the dough crumbs off my clothes, the phone rang: "Hello? Jiang Xia from the Machinery Factory!"

"A machine factory? You little brat, you've moved to a different place? What are you doing at a machine factory?"

Li Changfu, who hadn't been seen for a long time, rang out in a loud voice on the phone.

"Master! Oh, you've been released? Have you been promoted?" Jiang Xia recalled Secretary Liu's pointing to the sky, and her heart stirred. She asked cautiously.

"What do you mean you've been released? You little brat, you never say nice things! Hey, tell me first, did that bastard Li Huaide bully you and you ran off to the machine factory? Which machine factory?"

"Hehehe, Red Star Comprehensive Machinery Factory, Master, I'm in real trouble!" Jiang Xia was overly excited upon hearing his master's voice. Remembering the tortures the big shots had inflicted on him, he felt a deep sadness welling up inside him.

Just as he was about to say something more, the door was abruptly pulled shut.

Jiang Xia turned his head and glanced at it, then continued to complain to his master.

"Master...you have no idea how badly I've been bullied. I finally managed to get a truck, but after only a few days, someone stole the backup. I even got a 'Flying Cat Car,' but before I could even ride it once, someone else stole it too...waaaaah."

"Oh, and another thing, there was a DES encryption system I used for a test, but I didn't even play with it..." Wait, no, that's not fun, I'm not playing with it...

"Hiss... Is there such a factory in Beijing? I've never heard of it." Ignoring Jiang Xia's mutterings, Li Changfu asked this question with some doubt.

"It's just a steel rolling mill that was converted!"

"Hey, you little rascal. You're still in the same old place after all this time..."

"Alright, alright. Make a note of who got bullied first. When I get back, I'll take you to their door and give them a piece of my mind! Don't you know whose apprentice you are!"

(⊙o⊙)…It seems like we've gone too far. If Master knew who those big shots were, would he still say to go and fight them?

"I'll let you in on a secret, your master really leveled up! I'm level 2 now!" Li Changfu on the other end of the phone was extremely proud, squinting his eyes and humming a little tune.

"Wow! Isn't that a proper deputy chief engineer? Congratulations, congratulations... Master is still as sharp as ever, he will surely make even greater contributions to the motherland..."

"Alright, stop flattering me. We can talk about other things when we get back. I have a question for you to think about: how can we cool the gas extremely quickly?" Li Changfu was very pleased with his precious apprentice's praise, but seeing the disdainful looks from his comrades around him, he coughed lightly twice and got to the point.

"That equipment for the refrigerated train, Master, didn't the Ministry of Railways say they'd sent it over?"

"Not enough! It's too slow! I even took the whole thing apart and tried it, but it didn't work! It's polluting, and it consumes too much energy. You know, I haven't even finished running the centrifuges here..."

Tear it down! Tear it down!

Well, you guys are the only ones who can make the railway giant suffer in silence...

Jiang Xia silently gave it a thumbs up while simultaneously racking his brains:

"If you want to save energy, how about using a 'fire-powered refrigerator'? The canteen at the machine factory is using them, they're super economical, they just use gas from the steel mill..."

"You unfilial son, are you trying to send me to my death prematurely?"

Uh, remembering where his master was, Jiang Xia slapped his forehead.

Oh dear, no, I really can't think of a method right now.

"Master, is this urgent? Let me think about it for a couple of days..."

"It's not too urgent, but if you figure it out sooner, you can eat your teacher's wife's dumplings sooner!"

After I finished speaking, I heard a busy signal on the other end.

After hanging up the phone, Jiang Xia pulled out a pencil stub, picked up the half-eaten pancake with one hand and took a bite, while unconsciously drawing circles on the paper with the other.

Energy saving, rapid cooling, and no medium... Ugh, what a headache!

Ugh, anything even remotely related to key elements is never easy to deal with. But it seems there really is such a thing, something like a demon?

Ok?

Fairies? Hehe, catching an ice fairy and putting it in a big iron can should satisfy Master's request, right? No, in China, it should be a dragon?

Ice Dragon?

Haha, Jiang Xia's head is full of wild ideas right now, just letting his mind wander. Who knows, something that can cool things down quickly and save energy will pop up.

"Snack Buckle"

There was a knock on the door.

"Xiao Jiang, are you done with your work? Can Uncle Li come in?"

"Oh, Uncle Li, please come in, please come in..." Jiang Xia sketched a pipe on the drawing. Out of his longing to eat his teacher's wife's "dumplings", the boy became rational again, and all thoughts of human relationships and social etiquette were thrown to the corners of his brain.

However, Li Huaide was not angry.

He placed the two canisters of tea on Jiang Xia's table, glanced at Jiang Xia's blueprints, and immediately shrank back, walking to a small table to the side.

He unscrewed the hard-shelled paper tube of the tea box and poured the tea leaves inside into the tea canister that Jiang Xia had taken from his master.

While leaning to one side, he chatted casually, saying, "Xiao Jiang, tomorrow Uncle Li is taking the factory comrades to Tianshan to provide support. Yang Youning and I discussed it tonight and decided to have a farewell dinner for everyone. Come along and give everyone a boost!"

"Also, the corresponding blueprints need your signature..."

"Jingle Bell……"

Before Li Huaide could finish speaking, the phone rang again.

Jiang Xia frowned, ignoring the ringing bell, and continued working on the drawings.

"Xiao Jiang... should we answer it? It's a red phone call..."

Li Huaide leaned forward, pointed to the microphone that was about to pop up, and weakly offered a suggestion. This shrewd man had overheard Li Changfu cursing him when he came over.

Although the guard at the door closed the door so he couldn't hear what was said afterward, a misunderstanding needs to be resolved!

Interpersonal relationships aren't like having a wife, where you argue in bed and make up before you get out of bed...

"You can answer it, I'm busy..."

Jiang Xia drew two interfaces on the blueprint tube. While his brain cells were being frantically squeezed out, the general shape was also drawn.

"Hmm? What should the ratio of hot end length to cold end length be again? Shall we try 3 times first?"

Listening to Jiang Xia's mutterings, Li Huaide glanced furtively at the guards at the door and quickly grabbed the phone.

"Hello, this is the Jiangxia office of the Comprehensive Machinery Plant..."

"Huh? Who are you! How dare you answer this phone!"

Thanks to the special care from the Ministry of Posts and Telecommunications, Jiangxia's telephone may look unremarkable, but its radio system has been tuned to be extremely well-tuned. Not only is the annoying static completely filtered out, but even the sound quality of the handset is excellent.

Li Huaide recognized the voice immediately; it was that bearded man's voice.

"I'm the deputy director of the comprehensive machinery factory! Boss, you've heard my production reports before!"

"Oh... let that kid answer the phone!"

Uh, he looked at Jiang Xia with a pleading gaze.

But this absolutely rational little brat remained unmoved, simply continuing to calculate a certain formula.

Li Huaide wanted to bang his head against the wall.

You little brat, didn't you love chatting with these big shots the most? How come you've changed your mind?
