A nation's industrial development begins with junior engineers.

Ah, the cricket is digging a hole.

I anticipated your plans!

As soon as he received the notice about militia training, Jiang Xia knew he wouldn't get any benefits, so he made preparations well in advance.

Haven't you noticed that the scanner hasn't been turned on for the past few days? It's all because of this that I'm saving up my energy.

Waving goodbye to the Iron Army.

Jiang Xia nodded to Sister Wei Hong, and they each took out a flat object from their bags and assembled it with the round stick in their hands.

The two men bent the object upright, making it resemble a hoe.

Then, Jiangxia went into overdrive, kicking up clouds of dust.

It has to be said that digging a hole is much faster with a hoe than with a shovel alone.

By the time everyone was exhausted from digging, Jiang Xia and his friends had managed to create a two-meter-deep pit. While everyone else had a rectangular frame, the little guy had dug a hole!

Wang Kui, fearing he might bury himself in the ground, stood to the side, watching warily.

Wang Kui noticed something amiss and, taking advantage of a lull in everyone's breath, picked up the object in his hand and examined it for a while.

"Something new?"

"An entrenching tool, it's just a little bit of extra functionality."

Wang Kui scraped the edge of the entrenching tool with his hand, straightened the blade, and chopped it down on the wooden stake next to him, breaking it in two with one stroke.

"The logistics department will cry if they see you using alloy steel to make this thing!"

"Tch, it's just ordinary stainless steel. If the material properties aren't good enough, they just make up for it with heat treatment."

Yes, that's true.

The latest quenching oil was improved by Teacher Zhu based on the special oil for the "Little Cannon" gears.

He's a real expert. After Jiang Xia explained the ingredients of the special oil, he suggested adding some potassium nitrate to it for better results.

And so, the entrenching tool in Jiang Xia's hand was among the first to benefit.

"Yes, militia! Keep going! You're already behind!"

Jiang Xia took the entrenching tool and glanced at the movements on the other two sides.

Teacher Zhu's students are young and energetic, still kicking up dust, while those on 723's side are mature and steady, looking slow, but every shovel they use brings up a large amount of mud.

Bah! I don't believe it! Watch me unleash my full power...

hmm~

As a result, I couldn't straighten my back.

The pit has been dug, but unfortunately it's still oval-shaped.

The old company commander slid over in his wheelchair and took a look. "Not bad, you can bury the little notebook's tiny tank inside."

"Therefore, the winners are the school's children!"

"Come on, kids, one egg each. Don't skimp on them!"

The old company commander snatched the entrenching tool, examined it in his hand, and led the young men away slowly, singing "Returning from Target Practice."

Wang Kui carried Jiang Xia on his back and drove him home in a Yellow River jeep.

“Behave yourselves for the next two days. ‘Big Guy’ has noticed someone who’s acting strangely.”

"Tsk, I've never been ice skating on Shichahai Lake, not even once. 'Big Guy'? The one from Jinan, you know?"

"Yeah, he ran into someone yesterday who said he'd also run into someone in Jinan. He tried to catch him, but failed."

"Okay, then I can take the next two days off from work?"

Jiang Xia's eyes lit up. Wasn't this exactly what he wanted? Staying home and working on transistors was much better than foolishly digging a huge pit.

"Jiang Xia is a good comrade!"

Imagine an old man patting you on the shoulder and saying, "Oh my, I'm about to fly!"

"Dream on. This training is conducted from top to bottom, and there are military police around. Do you want to get a reprimand? Besides, isn't Engineer Liu from 723 going to use their guns for testing tomorrow? Don't you want to fire a couple of shots?"

Well, okay, this is a good opportunity to bring up the improvement plan. We should at least increase the magazine to 30 rounds; 20 rounds is just not enough.

Change my ass!

Once you get your hands on it, you realize that the people at Factory 723 have designed this gun to its fullest potential.

Why use a 20-round magazine?

Because the poor rabbit's copper resources have always been pitifully scarce, the 7.62*39mm intermediate cartridges produced earlier used steel casings and 20-round magazines, which, when fully loaded, could just maintain the center of gravity of the gun.

Only in the last two years, with the improvement of technology and the invention of copper-clad steel, has the quality of bullets improved somewhat.

That's why when shooting wild boars, Dazhu would immediately pull the bolt after firing the first shot with the Type 56 semi-automatic rifle, just to avoid jamming.

Moreover, while possessing automatic firepower, this gun also retains the characteristics of a rifle. With the bayonet extended, its total length of 1342mm allows soldiers skilled in bayonet fighting to unleash their full potential.

Jiangxia even saw a paratrooper model with a folding stock.

If it weren't for the fact that the era was different, Jiang Xia would have thought that the 81-bar race had appeared ahead of schedule.

Watching the one-armed veteran in the "veteran workshop" fire two shots with this gun, which went through a bullet hole, Jiang Xia felt that he shouldn't try to teach others.

As long as the manufacturing process of this gun is guaranteed, it will be of good quality! Isn't that exactly what Project 301 is doing?

What? You're saying the gun is too long and not good for use in the jungle?

Brother, don't you know the background behind the development of this gun?

That was for switching sides with the Big Brother, since the battle locations are different.

Jiang Xia has always believed that weapon systems are not about being advanced or not, but about being suitable or not.

Didn't you see how skillfully the guy wearing the headscarf used that gun later?

If you can't offer any suggestions, then just keep working on Project 301.

It's a systematic project, and there are many problems to solve.

I had just discussed the balancing mechanism with Teacher Zhu when my master grabbed me to check how to solve the balancing problem of the rotary feed mechanism.

"The ball screw is rotating and feeding the feed into the system!"

"Master, have you forgotten the feed system of that German lathe? With the machining center, we can easily produce high-precision lead screws!"

Li Changfu patted his forehead: "I really forgot."

"By the way, how's it going with those machining centers we gave to logistics? If possible, get one set ready first, there's space waiting to use it!"

Jiang Xia flipped through his notebook: "If we need it, we can pack it up and send it away tomorrow."

"However, the installers still need training. The connection method of the core components is a bit different, so we need to be very careful."

"Is it difficult?" Li Changfu frowned.

"It's not that difficult, it's just that the connection point is a little awkward in order to achieve three-axis linkage, so it needs to be connected first..."

"stop!"

The old man scratched his hair, which he hadn't washed in days, and walked around the table.

"Is a two-day training program possible?"

"That probably won't work. There are quite a few places that need lubrication, and many points to maintain. Unless I can crack open their brains and pour it in."

"The price of high precision is troublesome maintenance..."

Hearing Jiang Xia's reply, Li Changfu felt annoyed again.

"If I split you in two, would you still be alive?"

Jiang Xia crossed his arms and said, "Master, have you taken a fancy to that talented young man outside? I agree, but he has to be the eldest brother!"

"Get out of here! Wait outside!"

"Master, before I leave, let me make this clear! I can go anywhere—north, south, west, I'm fine with anything!"

Li Changfu's hand holding the microphone suddenly stopped. "You know?"

"I don't know, but a railway soldier once told me something."

"I want to go to the places where my country needs me most."
