A nation's industrial development begins with junior engineers.

"Jiang Gong! You've hit the bullseye three times in a row!"

"Wow! Impressive! By the way, do you have any leftover engines from the ones we modified to have larger bores? If the explosion wasn't too serious, you could salvage them and make a speedboat for the navy to use as a rapid response vessel."

"Uh... they're all left. But it seems they don't care about speedboats anymore..."

"what?"

Even after Zhao Bin explained everything in detail, Jiang Xia still looked incredulous.

What the heck? A big firecracker and a sea snail, and they encountered this inexplicable thing during the test firing. And...five pairs of wheels?

Looking out the window, Jiang Xia shook his head as the Jiefang truck laboriously dragged several chassis into the excavator production workshop next door.

Is this the curse of the Machine God?

Fortunately, the two things they attacked belonged to Little Karami, and weren't worth drawing the world's attention to this country still struggling to survive. (As it turns out, the kid was wrong.)

No, it's best not to get too involved with the five wheels. If something unexpected happens during the test drive, it could cause some trouble.

After all, aircraft and ships are from hostile forces, so any problems they have can be covered up.

The five-wheeled system is problematic; if something goes wrong, we'll have to confront Big Brother. This king of land warfare is currently being deployed in large numbers by the Alliance along the border.

The idea of ​​Chen Bing having a million-dollar army is truly frightening.

The smoothbore cannon produced by mechanical extrusion, and the laser rangefinder, are probably exactly what Comrade Fanzhou urgently needs.

Historically, the old Leopard could easily take down 10 T-34s, right? We don't need much, taking down 5 will suffice.

Hoo hoo hoo~~

"By the way, Engineer Jiang, the Navy said that we should just keep this information to ourselves. Whether to spread the news or not, whether to publicize it or not, well, that still needs a decision from above."

"Okay! Got it! Shall I hang up now?"

"Hey! Engineer Jiang, I'll bring you some frozen fish in a couple of days! A lot of fish got fried on site! I just don't know if they'll thaw by the time they get there..."

Oh, by the way, Factory 331 does have a cold storage facility.

Oh, I think I forgot something, something related to frozen fish...

"Jiang Gong? Jiang Gong?" Zhao Bin's heart skipped a beat when he heard Jiang Xia stop talking after hearing about the frozen fish on the other end of the phone.

Oops!

Could it be that the fishermen aren't satisfied with the frozen fish? Well, that makes sense. They're frying mostly large yellow croakers. They look nice and golden, but there's just too much of that stuff; the fishermen are feeding it to pigs…

Moreover, freezing fish is still quite troublesome. There are no cold storage facilities at the port, so we have to ask the relevant factories for help... We do have a large cold storage facility in our own factory, but it's a bit far away, and by the time we send it there, it will have already gone rotten.

Just as Zhao Bin was wondering if he had made a mistake in flattering Jiang Xia, Jiang Xia spoke up again: "Director Zhao, when you introduced the cold storage, did you study their equipment and try to copy it?"

"Cold storage?"

"Oh, I've seen it. It's pretty simple, just a compressor plus a condenser and an evaporator. The only problem is that the refrigerant is a bit hard to get right now, but otherwise it's fine..."

"Really?"

“Then…” Zhao Bin paused, in his eyes, the wise and capable Engineer Jiang was not the kind of person who would ask such an idiotic question.

"Engineer Jiang, please wait a moment..."

Zhao Bin rushed out of the office, grabbed Comrade Jin Guang who was frowning as he wrote a report, and asked:

"Sir, may I bring a technician to answer Engineer Jiang's questions? Your security personnel can listen in."

Comrade Jin Guang is still scratching his head:

Sigh, this report is really hard to write. In the past, it always involved a bloody battle, and the losses in personnel and equipment would give him enough material to write a long, detailed account. But today's battle was easily resolved by a few "little flying rods" that flew from dozens of kilometers away. The only injury to the entire fleet was when a new recruit accidentally got burned while trying to extinguish the 10,000-ton landing craft…

Um, could you write about the cracks on the cement boat?

Shouldn't this be considered battle damage?

Interrupted from his train of thought, Comrade Jin Guang waved his hand upon hearing Zhao Bin's question: "Go on, go on. Um, wait for me after you're done. I'll ask this little brat what he wants..."

Pshaw, a commander of such stature, trying to "compete for favor" with me?

While inwardly grumbling, Zhao Bin quickly led a technician back to the phone:

"Jiang, I just asked the surveying manager at my factory. I asked him to report to you about the cold storage."

"speak!"

"Jiang, we've done a thorough investigation of the imported cold storage facility. We can manufacture most of the components, but the tube-plate condenser is a bit of a problem..."

"Hmm, is it a problem with the connection between the copper pipe and the aluminum fins?"

"Hey! As expected of Engineer Jiang, after our factory manager bought that cold storage unit, he said it was too expensive and was thinking of making a copy and selling it to our brothers..."

Before he could finish speaking, the technician was hit in the kidney.

"Enough with the nonsense! Get to the point! Engineer Jiang's time is precious!" Zhao Bin gritted his teeth, while the confidentiality officer in the team became interested and kept taking notes.

The technician rubbed his lower back in frustration. Luckily, I'm young, or I would definitely have "gotten a go" with you.

"That's how it is. That cold storage is from the US, and I don't know how they welded the two materials together. Anyway, our technicians tried many times, but they never succeeded..."

"Hmm, simple, friction welding will do. Besides that, are there any other difficulties you face in replicating the cold storage?"

"No, not really... Oh, there's also a valve, the expansion valve that controls the refrigerant's transition from a high-pressure liquid state to a low-pressure liquid state..."

"Expansion valve, that's easy to solve... But I'm quite curious, can you manufacture the compressor inside?"

"Hey! We didn't make it. There's a gas compressor factory in Northeast China that made this thing a few years ago. Apart from being a bit big, it's perfect!"

"Gas compressor factory?"

Jiang Xia looked at Lao Wang suspiciously, but Lao Wang shrugged: "It's the old Shenyang Automobile Factory. I have some comrades there. When the task of manufacturing the Jiefang trucks didn't fall to them, they went and started tinkering with those compressors..."

Jiang Xia gave a thumbs up. At this moment, he also found the information about Shenyang Automobile Factory in his memory. Isn't this the manufacturer of the famous "Jinbei car" in later generations?

Tsk, another remarkable one.

"If the compressor is large, can it be installed on a truck?"

"That's tough! It's already half the size of the car front..."

Tsk tsk, if it's a big one, it's a bit annoying. This set of blueprints for the refrigerated truck I won in the lottery includes everything, even detailed blueprints for supporting equipment like friction welding, but it just doesn't include the compressor...

Without a small compressor, the refrigeration system is just for show...

"Jiang, are you done asking? I still need to look for a place with a cold storage. Once it's frozen, I'll apply for a railcar and send it to you! Although this big yellow croaker may not seem like much, but..." Seeing that the phone went silent again, Zhao Bin assumed that Jiang had finished getting the relevant information, so he took the phone and started explaining again.

"Director Zhao, wait a minute, what did you say in the previous sentence?"

"Find a cold storage..."

"A little further back."

"Request a freight car!"

Yeah! The compressor is too big, so just install it somewhere that can pull it!

You're the one, Boss Iron!

"Director Zhao, freeze that batch of fish for now. I'll send you the blueprints and equipment tomorrow. Could you modify a batch of refrigeration systems to fit the dimensions of the train carriages?"

"Uh, that's no problem." Zhao Bin thought of the piles of old, counterfeit cold storage parts in the factory, and his heart warmed up again. This Engineer Jiang is going to help us clear out our factory's old mess!

"However, we're not familiar with the railway system..."

"Hey, you don't need to worry about that. Just tell the people at your factory!"
