A nation's industrial development begins with junior engineers.

The moon was yellowish, like a sesame seed cake with a bite taken out of it.

With a large red bump on his head, Jiang Xia continued to explain and assemble the equipment.

With the cylinder head bolts tightened, the first diesel engine officially rolled off the production line.

Jiang Xia wiped the sweat from his brow and shut down the green fault analyzer. He nodded to the waiting crowd.

Li Changfu and Yang Youning exchanged a glance and then looked at Jiang Xia.

"Try?"

"try!"

Li Tiejun, who also had a large bump on his head, took out the fuel and engine oil he had prepared beforehand and added them into the engine.

Several iron chains threaded through the gourd were fastened to the engine, and with the sound of the chains rubbing together, the engine was slowly hoisted onto the starting frame.

Ready!

Jiang Xia took a crank and inserted it into the front port of the engine, ready to exert force.

Just then, Wang Kui rushed forward and grabbed Jiang Xia's hand.

"and many more!"

"I'll do it!" Wang Kui scratched the tuft of hair on Jiang Xia's head and pulled him behind him.

Jiang Xia was slightly taken aback, then smiled and said, "Brother Wang, it's alright, I'm confident."

Wang Kui glared: "Execute the order!"

Then he looked at the others and said, "You all step back!"

Jiang Xia, who was getting nervous because of Wang Kui, pulled out the analyzer again and checked it once more.

"Twin-cylinder, two-stroke diesel engine - model unknown"

"Simulation run - passed"

"Fault warning - Gear set tolerance too large, camshaft..."

Jiangxia turned it off before it finished displaying. It was just a warning anyway, nothing serious.

After all, this set of parts is all handmade, so it's already good enough that it meets the assembly requirements.

As Wang Kui bent over and exerted force, a sound came from inside the engine.

"Uuuuuuuuuuuuuuuuuuuu"

"Da da da~~~~"

The engine suddenly spewed out a plume of black smoke, then began to spin merrily.

"It's turned! It's turned!"

"We did it! We did it!" Ma Weihong excitedly threw down her notebook and rushed to Jiang Xia's side, stroking Jiang Xia's head repeatedly with both hands.

"How come you're so smart!"

Li Tiejun rushed over, picked up Jiang Xia, and tossed him into the air, shouting, "I knew you were something else!"

Seeing Jiang Xia fly up, Wang Kui just chuckled and spread his arms, ready to catch him.

Yang Youning's mouth dropped open, his face filled with disbelief, which was quickly replaced by ecstasy.

"Old Li? We've succeeded!"

"This is just the first step! We have to wait, we have to wait!" Li Changfu's eyes were bloodshot, his lips trembled slightly, and he stared intently at the engine.

Master Qin was so excited his face turned bright red, and the veins on his forehead bulged slightly. He pulled Master Lin, who was standing beside him, along with him.

"See that? The engine's running! I made the parts inside!"

Master Lin nodded repeatedly: "I made the cam inside!"

"I made the pistons inside!"

"I installed the valve!"

"I welded the crankshaft and connecting rods!"

The master craftsmen announced the parts they had made, their eyes sparkling as they looked at the engine.

"When the wind rises and the clouds fly, we workers have strength!"

"Build a diesel engine, uh..."

Li Tiejun was inspired to write poetry again, but he stopped halfway through and looked at Jiang Xia.

"To contribute to the motherland!"

"What a poem! What a poem!"

This time, it wasn't just the two brothers bragging; the whole audience cheered.

"By building diesel engines, I will contribute to the construction of my motherland!"

After the initial excitement, everyone was exhausted.

Yang Youning invited all the master engineers to the guesthouse and arranged accommodations for them. A few technical staff remained on site to continue observing the engine's operation.

Li Changfu stubbornly refused to leave, insisting on seeing it with his own eyes before he could feel at ease.

Jiang Xia couldn't dissuade him, so she dragged Li Tiejun over and carried the sofa from the office. Li Changfu lay half-reclined on the sofa, listening to the engine's clattering sound, and slowly drifted off to sleep.

Jiang Xia glanced at the remaining parts, his eyes flickering.

"Iron Army, can you still move? Let's make another one!"

"No problem, with my physique, I can handle two more all-nighters!"

As the assembly proceeded, Li Tiejun was somewhat bewildered.

"Hey, hey, why is it different? Jiang Xia, why is this a single-cylinder?"

"Shut up, do as I say. There's no time for explanations; the wheat seedlings in the field are waiting for water!"

…………

Li Changfu woke up and nodded in satisfaction as he looked at the still-running engine in front of him.

I glanced at my watch; it had been running for four hours. It's still spinning, so it seems the problems I was worried about—grip grinding and engine failure—have been resolved.

I don't know how much horsepower it has, but judging from the way the flywheel is spinning, it should be quite high.

“Da da da da da~~”

"Da~~~~Da~~~~"

Wait, why is there the sound of two engines?

Li Changfu listened intently, glancing to the side.

"Master, you're awake?" Jiang Xia asked, her eyes bloodshot, as she poured a glass of water and handed it to him.

Li Changfu took small sips of water, carefully examining the new engine.

This new machine looks much smaller than the previous one. It's square and boxy, with many covers still attached. A huge flywheel is propped up next to the machine and is turning slowly.

If the engine on the starting frame is like a wild horse, moving swiftly; then this new one is like an old ox, seemingly unhurried, but giving the impression of being extremely powerful.

"This is?"

"Single-cylinder, two-stroke! Perfect for well drilling! That twin-cylinder one is a bit too fast, this single-cylinder one is just right, powerful!"

With a whoosh, the door to the small workshop was pushed open.

Yang Youning appeared in the doorway, his face covered in sleep. "How is it? How is it? Is the machine still working? It didn't explode, did it?"

Li Changfu, hearing the harsh words he uttered, casually tossed a nut over to him.

"You've blown it up, but the machine won't!"

The nut traced an arc before gently falling to the ground.

Yang Youning didn't dodge, but just stared wide-eyed at the machine next to the starting frame.

"Click," the nut landed precisely on Yang Youning's forehead, but he seemed oblivious, simply walking quickly to the single-cylinder engine.

"Wow! Another one. But why does it look different?"

"One is twin-cylinder, the other is single-cylinder. Of course they're different. Master, factory manager. I'll take this single-cylinder one out later."

"Take it out?" Li Changfu was a little reluctant. "The power and torque tests haven't been done yet."

"Hey, I left you guys a twin-cylinder one to play with, I need to use this machine to drill a well. Industry supporting the countryside, Master!"

"If all else fails, since we gave the assembly instructions to Li Tiejun and the others yesterday, why don't you have them assemble another one?"

Li Changfu thought about it and agreed. After all, farm work couldn't be delayed.

What's more, this machine is made in-house. As long as we have enough parts, we can make as many as we want.

No need to resort to tricks or play the victim anymore, no need to beg and plead, no need to sell your face.

No need to look at any other people's faces or colors!

Hey, I, Old Li, am quite generous. I made two engines at once, one for testing and the other just sitting there!

I, Li Changfu, am doing this now, and no one can change my mind!
