A nation's industrial development begins with junior engineers.

As Director Liu hung up the phone and scratched his head, wondering if he had been too hasty, a group of young men with buzz cuts gathered in front of the open window.

"Factory Director! Factory Director! We're having an organizational meeting. Didn't you say last time that you were going to talk about the battle you participated in?"

Factory Director Liu was taken aback: "Which one?"

"That was the battle you led under your old commander, the one where you marched a thousand miles! You always praised commanding that battle, saying it was 'more of a battle of wits than a battle of courage!'"

"Oh! That must be it! Not everyone has the guts to go deep into enemy territory and plant a nail! Let me tell you..."

When Director Liu heard the young men mention the battle, his face immediately lit up with excitement. Urged on by the group of young men, he headed towards the workers' activity center, completely forgetting about the huge mess he had made.

But don't blame him, after all, no one expected those two to show up in person...

……

Meanwhile, Jiangxia's situation at this moment is somewhat mysterious.

For the first time, he used a scanner while entering a state of rationalization.

"Hey, I thought this 531 prototype was copied from the Russian BRT-50, but it turns out it's a completely new design. Otherwise, they wouldn't have made such a basic mistake..."

"Hmm~~ No three-proof protection, but why didn't you do a good job with the shock absorption of the walking mechanism? Do you really think our soldiers are potatoes to be tossed around?"

“A little jolting isn’t out of the question, after all, our soldiers have absolute faith. But increasing the diameter of the road wheels just to lift the 122mm howitzer won’t work. Why not change it to five pairs of small-diameter double-flanged road wheels, plus three pairs of track rollers? That would optimize the road wheel layout…”

"Hey, 260 horsepower, why do you have to carry a cannon? Didn't you even consider the load capacity of the running gear... Are you trying to make the tank advance halfway before stopping and waiting for you?"

Tsk tsk, let's change it.

The first thing to change is the vehicle's shock absorber travel. 170 mm is not enough. It should be increased to 210 mm. The mechanical spring shock absorbers on both sides of the vehicle are not worthy of our brave warriors. Even excavators are using telescopic hydraulic shock absorbers. Don't you guys know about that?

Our soldiers are incredibly lovable, unlike the "mobilized soldiers" from the Russians.

Hmm, if we extend the vehicle body by another ten centimeters or so, the center of gravity will be centered. With the addition of detachable floats, I don't believe it will still gurgle when it goes into the water!

After a flurry of activity, the 531 prototype vehicle, while still largely unchanged in appearance, has undergone a complete transformation inside.

Okay, that's enough for today. If we keep going like this, we'll reach the critical point.

Seeing Jiang Xia stop writing, Old Wang turned to look at the drawing that only had the title "Infantry Fighting Vehicle" written on it, but below it was only a rough sketch of its external shape. He scratched his head in confusion.

"What are you doing? I thought you were going to redesign something, why are you modifying someone else's drawings again?"

"Just trying to be lazy~"

"what……"

"Haha, just kidding. I don't really know if this thing works..." Jiang Xia paused here.

That's true. Don't forget that audacious factory director from Northeast China. Just based on the crimes he committed against that poor five-wheeled RPG-7 with its modified version, Jiang Xia is even considering whether an "infantry fighting vehicle" is really necessary.

Think about our upcoming battles: one on the plateau, the other in the jungle. These are places where ordinary vehicles can't pass, so even if he brings out the BMP-1, it doesn't seem to be of much use.

"Besides, this 531 was also the result of someone's hard work, and it was also an order from above. Its existence has its reasons. There may be some aspects that I haven't considered. I'll hold off on discussing my idea for now..."

Jiang Xia waved his hand and pointed to the fan blades that Tie Jun had brought at the door.

"Stop talking nonsense! I didn't notice it when I was focused, but now that I've stopped, I realize the stench has filled my nostrils. Blow it out! Blow it out!"

"You're right. If it really doesn't work out, we can switch rooms. Li Huaide wouldn't refuse you even this much face, would he..."

Old Wang waved his hand dismissively, picked up the Z-shaped key, and started the engine of the little powerhouse.

"Spit it out, s ......"

"Pah, you know how many people work in the steel rolling mill these days. If I switch to a simpler system, won't more people have to come in and suffer? We don't do that kind of immoral thing..."

Jiang Xia shook his head, trying to shake off the strange smell that had invaded his nose.

"Hey..." Old Wang let out a soft sigh that was hard to decipher, but a smile appeared on his lips.

Once the engine speed was even, Lao Wang tried to move the linkage mechanism. Suddenly, draft papers from Jiangxia's desk flew everywhere.

Wow, that's incredible!

"Old Wang, are you stupid?!"

Seeing the blueprints fluttering in the air like butterflies, Jiang Xia jumped up to reach them, and Lao Wang rushed over to help.

For a moment, the two were like kittens chasing butterflies. The little powerhouse engine sputtered, "Ptooey, ptooey, ptooey..." How stupid! Didn't you know to turn me off before cleaning up?

"How the hell was I supposed to know this thing was so powerful! I thought it would be like that creaky ceiling fan in the conference room..."

"Hey, you're really weird, aren't you? I just realized that everything you've made is an enhanced version?"

"That's right! This is a three-wheeled one; the five-wheeled one is even more powerful! The air delivery channel is at least 8 meters long! The latest air fryers use this type of impeller, which I call the 'high-powered version'!"

Hearing Old Wang's praise, Little Dumb Hair proudly stretched out his paw and waved it.

"Stop talking! Hurry up and grab the blueprints. If Secretary Liu finds out, do you think he'll emphasize the confidentiality rules to you?" Even Old Wang, who's always been around this unreliable brat, has evolved. This吐槽 (tu cao, a Chinese internet slang term for sarcastic or witty remarks) is quite something!

"Hehe, you know what, catching it like this feels just like catching dragonflies when we were kids..."

"Tsk, the dragonfly you caught was pretty clumsy. The dragonflies in the south are much bigger; you could make a whole plate of stir-fried meat from one of them..."

Ding Dana came back excitedly, carrying the braised pork that had been heated up in the cafeteria: "Engineer Jiang, Engineer Jiang! I brought the braised pork you've been longing for!"

"Hey, what are you guys doing?"

"Forget about the meat, hurry up and grab the blueprints. The chassis drawings I wanted to give you seem to be mixed in with them..."

"okay!"

Honest Ding Dana put down his plate and joined in this inexplicable activity.

The engine by the door was still spitting out loud, "Did these good-for-nothings really build this? It's a disgrace to the machine..."

Fortunately, two elderly men appeared quietly and ended the farce.

"Young people are so lively..."

"But, Political Commissar, were those amazing things in front of us really made by that guy?" The old man with round-framed glasses put his hands on his chest and had a playful smile on his face.

Another elderly man took down the connecting wrench of the linkage mechanism.

"Where's the 'fiery' version? I'll bring one back later and see if I can make 'smoked beef'!"

……

The three people who had been jumping around excitedly immediately fell silent: "Commander?"

"Hahaha... It's so good to be young. I thought you'd been wronged, so I rushed over without even eating. Look at you, you're living the good life! You have wine and food, life is good to the fullest..."

The old man helping Jiangxia sell pots pointed to the braised pork that Ding Dana had just put on the small table and smiled happily.

"Come on, Lao Liu, don't stand on ceremony with them. First, eat your fill, then deal with them."

Another elderly man readily agreed: "That's great! Braised pork belly. I tried a small piece back in Dingtao years ago. Now my wish has finally come true!"

Ding Dana suppressed his excitement and opened the two large, dark ceramic jars: "Boss! Our factory director always says he was one of your soldiers back in the day... This is some Quancheng beer he asked me to bring... It's delicious!"

"Quancheng? Oh, Liu Guanghui, is that right? Hahaha, not bad, not bad..."

The two elderly people looked at each other and smiled.

They just didn't notice that a drawing filled with symbols that ordinary people couldn't understand fluttered out of the window...
