A nation's industrial development begins with junior engineers.

Getting it running is simple; don't forget that Factory 331 received the blueprints for a four-cylinder diesel engine. Although it's not a perfect match for marine applications, using two specially enlarged cylinder versions is more than enough to power a small cement boat of less than 5 tons.

Moreover, the small boat had been prepared long ago and was now towed behind the observation ship, swaying back and forth.

The boat wasn't big, but it was packed with stuff, including a mechanical timer control system. Remember the self-feeding mechanical chuck that kid made early on? The principle is pretty much the same as that thing.

When the mechanical timer reaches a certain time interval, the small boat will perform maneuvers such as turning and veering according to preset values. If you don't mind the system's bulky and cumbersome nature, its only drawback is that it cannot stop automatically...

If you miss, you can only stop when the fuel runs out.

Tsk, what do you need a remote control for! Back then, the price of a remote control was enough for Comrade Jin Guang to build several cement boats.

However, Zhao Bin never considered the possibility of not being able to stop. The direct hit of the previous shot greatly boosted his confidence.

To enhance heat signal feedback, two more barrels of gasoline were loaded onto the small boat, which was then set ablaze to simulate the heat source of a large warship. Once the comrades on the observation ship started the small boat, the "Sea Rider" would be deployed again!

Woo-hoo-hoo~~

As Comrade Jin Guang watched the small target boat running happily forward, his steel-like arms tightened even more, so much so that Zhao Bin's tongue almost came out.

"Can something this small be seen on radar?"

After experiencing the "scholar meets soldier" treatment, Zhao Bin's arrogance, brought by the little tuft of hair, was severely suppressed. He forcefully bent Comrade Jin Guang's arm outwards:

"A corner reflector, that multifaceted metal block, increases the radar cross-section. See for yourself if you don't believe me..."

Looking at the radar screen, a green line swept across, and sure enough, a bright spot appeared. Comrade Jin Guang nodded in approval.

Wait a minute, how come this little wrecked boat is going so fast? It's already almost 32 kilometers away!

The arm that Zhao Bin had pried open slowly tightened back up.

"Tsk tsk, Director Zhao, you're not being honest. There's something strange about this engine..."

Before Director Zhao could answer, the radar operator started to panic.

"Report! The small boat is too fast and is already 35 kilometers away from my launch platform! If it goes any further, the radar may lose sight of the target!"

"beat!"

Once the command was issued, "Hailuzi-2" disappeared from the makeshift launch pad in the blink of an eye.

……

Our little rascal had no idea what had happened in that bathtub. After finishing the phone call, he went straight to the excavator production workshop.

There's a group of students waiting for Engineer Jiang to teach them!

After all, Yang Youning is only a novice; he can only operate the machine. The inventor of the machine has to personally demonstrate the basic repair and maintenance methods.

Modern excavators are far more complex than the modular equipment of later generations. They can't be fixed simply by adding grease. There are no maintenance departments now, so the operators have to take on multiple roles.

In addition, the chassis are currently too difficult to produce. Although the grassland tractor factory has agreed to provide support, production is still not easy. Moreover, the other party also needs to produce proper five-wheeled vehicles. The men on the grassland have put in the effort of training eagles, but in terms of production capacity, they still can't compare with the Red Star Steel Rolling Mill, which is a monster that works like crazy.

With the support of its revolutionary faith and processing capabilities far exceeding those of other domestic companies, Xiaodaimao can proudly say that in terms of processing capacity, Hongxing Steel Rolling Mill is number one!

However, being number one yourself is not enough. Industrialization is better when it is rolled out comprehensively. There are so many things that need to be produced that even if steel rolling mills were expanded tenfold, it still wouldn't be enough for the masses.

It must be separated!

Fortunately, Yang Erlengzi, that big scoundrel, is not around, and Li Huaide is now following the little brat's lead. Factory 331 is the little idiot's first pilot project.

Once there's a first one, there will naturally be a second.

Who is it?

Of course, it's our Sijiucheng Automobile Factory!

Liu Ye is still driving a Jeep that someone else's factory sent over for "experience" to pick up and drop off Jiang Xia's family. If he forgets about others, he'll be the subject of gossip.

What kind of product is that?

Mini wheeled excavator!

Looking at the mechanical booms piled up to the side, awaiting installation while stress was being relieved, our little guy immediately thought of miniaturization as a solution.

Jiangxia wanted to acquire some wheeled excavators for public works projects, such as digging irrigation ditches in the fields. In this case, small wheeled excavators would have a unique advantage.

After all, no matter how strong the off-road capability of a tracked vehicle is, it is still not as agile as a small one in some tight ditches.

The chassis intended for production at the Sijiucheng Automobile Factory are these small-wheeled models.

By this time, their factory manager and chief engineer had been wandering around the excavator production workshop for half a day.

"Little Jiang, Little Jiang! We're here!"

"Haha, thank you for waiting. However, I still need to give the students a lesson. Here are the blueprints, take a look first."

"You can sit in on this later. I'll explain the basic structure of an excavator to them. After you hear it, you might have some new perspectives on this thing!"

The young man spoke urgently, not giving the two department-level officials much explanation. Time is really tight in Jiangxia right now.

Listen first, then decide. If you think you can handle the job, then do it. If you don't want to take it, then Jiangxia should quickly find someone else.

The sooner water conservancy projects are completed, the sooner they will benefit the people. Minister Yang of the Ministry of Agriculture has been treating Yang Youning like a dog; we need to quickly find some fresh blood to replace him.

It's not right for a factory director to be spending all his time loitering on the construction site.

"Alright, comrades, gather around. Today we're going to talk about some key maintenance points for excavators and bulldozers..."

Xiao Jiang's Engineer Classroom is open again!

The factory director and chief engineer of the Sijiucheng Automobile Factory also sat down obediently and began to take notes seriously.

……

"Oh, I see! I understand why Engineer Jiang called us here!" The chief engineer of the automobile factory glanced at the blueprints and slapped his thigh after listening to Jiang Xia's explanation of the overall structure of the excavator.

"Talk about it!"

"He wanted to install the excavator's superstructure directly onto our 130 light truck. Well, it's not exactly a direct installation; some adjustments were made accordingly."

The two sat at the back of the classroom, whispering to each other.

"Look, the engine here has been changed to a four-cylinder diesel. Wow, that horsepower! We could use it to make a truck! Ah, it's such a waste that it's a big horse pulling a small cart!"

"And look at this..."

Pa~~

The factory manager of the Sijiucheng Automobile Factory bluntly retorted, "Enough with the nonsense, just tell me, can we do it?"

"It's possible, but we need to make technological improvements first! Also, if you hit me on the head again, I'll go back and tell my sister!"

"Pah! Don't try to scare me with your sister. So what if she knows the Shu Road? She'll go with me to the Shu Road, and I'll get my revenge on you!"

"You said you could do it, so I'll go and give Engineer Jiang a formal pledge right now!"

"Ah? Is it necessary?"

"Bullshit! Didn't you see the deputy factory manager from 331 who came to the meeting introduce the current benefits for his factory's employees? You don't want them? Damn it, they've actually gotten their first taste of meat from so far away..."
