A nation's industrial development begins with junior engineers.

After a barrage of flattery, Li Changfu finally calmed down and waved for Jiang Xia to wait outside.

Just then, Jiang Xia felt his stomach churning again and needed to have some more pleasure.

As soon as Jiang Xia left, the old man chuckled and scolded, "You little rascal!"

He picked up the phone and dialed someone he didn't know: "Hey, get me the XX department. Find Wang Chaogui, I'm Old Li from the steel mill."

"Old Wang, it's me, Old Li! Are you free tonight? Come over to my place!"

"Alright! I have wine, I guarantee you'll drink to your heart's content."

After inviting one person, Li Changfu picked up the next one: "Old Ren, how about we get together tonight?"

"A meeting? Tsk tsk, go ahead and have one. Don't come looking for me if you regret it later!"

"No regrets? Ha, detailed internal diagrams of the twin-cylinder engine, it seems I'll have to share them with Wang Chaogui."

After saying that, he hung up the phone abruptly, ignoring the questions coming from the other end.

"Hey, you old codger, hurry up! How dare you question my apprentice!"

After thinking for a moment, Li Changfu made one last phone call.

"Wang Kui, arrange a car for him. And while you're at it, get a blueprint tube, um, it's classified!"

Yang Youning saw Jiang Xia help his master into the car sent by Wang Kui.

"Hey, this old Li really spoils Jiang Xia. He usually walks, but this time he's actually riding in a car."

Yang Youning held onto the bicycle beside him, but it didn't feel appealing anymore.

Li Huaide brushed past him, even pressing the bell as he did so, leaving him with a dashing silhouette.

"Hey, you dog!"

The journey was smooth, and when they arrived at Li Changfu's house, Jiang Xia took out a tube of toothpaste: "Master's wife! Look what I brought you!"

The teacher's wife tugged at the tuft of hair on Jiang Xia's head: "You little rascal, it's enough that you're here, why did you bring anything?"

"Oh, look, Master's wife!"

"I saw it! This stuff is expensive. Put it in your room later for yourself. Your master's wife is used to using tooth powder."

It is indeed expensive. These days, a tube of toothpaste costs more than a dollar, while tooth powder only costs a few cents.

After saying that, he turned to Li Changfu and said, "Why didn't you tell me you were going to treat us? I only found out after Old Ren had already arrived home!"

"Hey, he's the one who can't be told what to do, and he's also the fastest runner!"

Li Changfu smiled mysteriously and held up the cylinder in his hand: "Don't worry, with this, you can give him a plate of pebbles to suck on all night."

The master's wife playfully slapped Li Changfu: "Why are you so mean! Fine, I won't bother with you guys anymore, but our Xiao Jiang has to eat meat!"

"Hey, wait! I don't care about anything else, you still have to make this pebble sucking game for me today! I won't be at peace until Old Ren sucks these pebbles today!"

There is nothing more to say next.

Old Man Ren pulled Old Man Wang, who had just arrived, and without even having time to eat, they busied themselves working on the blueprints.

Li Changfu sat at a small table to the side, drinking alone and watching his old friend bustling around with a smile.

Logically speaking, there's no need to look so closely. After all, both Elder Ren and Elder Wang provided support to the Sui Dynasty Emperor Yang's imperial garden back then.

The Russians provided several second-hand engines, which they disassembled and reassembled repeatedly, drawing up blueprints that filled several large filing cabinets.

Whether it's a legitimate blueprint or not, you can usually tell at a glance.

But we just couldn't make it back then, otherwise the engine we made would have had a lot of problems.

It's either leaking oil here, or jammed gear there, and some have even burst open.

A group of people were very frustrated. They were clearly the same parts, but why did they not work properly when they were put together?

Aside from factors like materials and technical personnel, the biggest issue is a lack of understanding of the purpose of parts and the assembly sequence.

We can only follow the map and imitate it blindly.

Jiangxia's blueprints were different; they not only detailed the manufacturing process of each part, but also specified how each part was assembled.

They can all be used directly as textbooks for diesel engines.

At first, the two elderly people occasionally argued, requiring Jiang Xia to step in and resolve the issues.

In the end, only gasps of surprise remained.

"So that's how fuel injectors work! No wonder our old ones never seemed to stop spraying!"

"Oh! So that's how you put the intake valve! A special clamp! Right, right, that explains how they got the locking spring in!"

"Hahaha! Let's drink a big toast!"

When the two old men finished their study and wanted to eat again, the dishes on the table had been removed from the table at some point.

Jiang Xia, with a greasy mouth, brought a plate of dark, gooey stuff from the kitchen and placed it on the table.

"Please, you two old brothers," Li Changfu said, grinning as he placed his wine glass down.

Old Ren took a closer look, and lo and behold, it really was sucking pebbles! He burst out laughing: "You little rascal, Li Changfu, you were just waiting for me here!"

What is sucking pebbles?

The pebbles, each one perfectly round and clean, were stir-fried in a pan with some oil, salt, soy sauce, and vinegar, and smelled quite delicious. They were a staple snack for the impoverished residents of Beijing, perfect for drinking with.

Li Changfu ignored him and looked at Jiang Xia: "Back then, this old guy insisted on calling me over there."

"What would someone like me, who works with rolling mills, be doing there?"

"Huh?" Jiang Xia's timely response was perfect.

He said, "That's just how mechanics are. If you can master one thing, you can master everything. And there'll be good wine and food when you go!"

"Oh!"

"But after some investigation, it turned out that wasn't the case at all. That guy was in a real hurry! In the end, he forgot about the promised food and drinks and just brought out a bowl of pebbles soaked in soy sauce. He said that those without skill could only suck on pebbles."

"Hi!"

"So, Old Ren, just tell me today, are you going to eat or not? No~~" Li Changfu glanced sideways at the blueprints.

Without saying a word, Old Ren stuffed a stone into his mouth.

"Hey, you really put some serious stuff in that pebble!"

Meanwhile, quite far from Li Changfu's home.

A detached villa, its glazed roof tiles illuminated by streetlights in the night, reflecting a vibrant array of colors.

A small car with an oversized grille and round headlights drove into the courtyard of the villa.

As soon as an elderly man got off the car, the courtyard erupted in excitement.

Some called him "Grandpa," some called him "Uncle," but the title "Big Leader" sounded rather jarring among the various forms of address.

After the lively commotion, two cups of coffee were placed on the desk in the small house.

A pair of gleaming golden scissors dangled at the bottom of the cigar, then snipped it off with a sharp cut.

One hand held a lit match close to the cigar.

A plume of smoke billowed from the old man's mouth, enveloping Li Huaide. The old man squinted, and Li Huaide's face appeared somewhat blurry in the smoke.

"So, that young man fixed that huge bending machine, completely ruining your plans?"

"Yes, boss. We had already spoken with the people on Big Brother's side. After that super-large bending machine is scrapped as planned, they will provide another one, and only I will be able to get it!"

"In this way, Yang Youning, who has lost his prestige, will have no choice but to step down and give way to a more capable person, so I can smoothly take over production matters."

Just like two years ago!

Two years ago, a smug look appeared on the old man's face.
