Courtyard House: In this life, I have a new home!

Sha Zhu hesitated for a moment, but in the end, he still carried the wailing, throbbing dog to the hospital. As for Director Zhou asking him to go back to work? He'd postpone that for later.

Making a late-night snack? It's still plenty of time.

Li Weidong went home, gave a few instructions, and then pushed his bicycle to head out.

Lin Yurou followed him to the door and told him to be careful while working.

"Goodbye, brother! Bring me something delicious when you come back!"

Xiao Xi waved her little hand and said.

"Okay, tomorrow's Sunday, I'll take you fishing."

Li Weidong waved his hand.

He pushed the cart to the gate and found Yi Zhonghai still waiting there.

Li Weidong ignored him and got into his car to leave.

"Wait a minute, Li Weidong, can you give me a ride?"

Yi Zhonghai shouted.

"I can't carry it, I'm not capable of that."

Li Weidong coldly uttered a sentence.

After saying that, he left only his back to Yi Zhonghai.

"Old Yi, what you did wasn't fair. He's the chief engineer, and you're just an ordinary worker. You expect him to mentor you?"

Yan Bugui chimed in from the side, "With Li Weidong's personality, it's no wonder he wouldn't bother with you."

"Never mind, I'll walk there."

Yi Zhonghai waved his hand impatiently.

"Wait a minute, something's fishy about tonight. You know what kind of person I am; there's absolutely no way I could have injured Bang Geng's hand like that. But this..."

Yan Bugui frowned.

"Alright, we'll talk about it when I get back."

Yi Zhonghai's face darkened. "This Li Weidong is a real sly one. He doesn't look like someone in his early twenties at all."

"Do you think he got his master's degree for nothing?"

Yan Bugui immediately chimed in, saying that he was now standing alongside Li Weidong in the ranks of intellectuals.

"By the way, keep an eye on your second son, don't let him cause any internal strife."

Yi Zhonghai reminded him, "The story about stealing the chicken was something he told Li Weidong."

Yan Bugui was a little confused. Yan Jiefang was turning against his own people? Did he have that kind of ability?

"Tch, he's already eighteen, and I still have to support him."

Yan Bugui shook his head dismissively. "Internal strife? I'm lucky he won't starve!"

He walked home with his hands behind his back and shaking his head.

Yan Bugui was unhappy that he hadn't managed to get a workstation today. But judging from Li Weidong's tone, it seemed he really was planning to give up his workstation. But how much would that cost?

The thought of spending such a large sum of money made Yan Bugui's heart ache.

As Li Weidong walked into the workshop, he immediately saw Director Yang, Secretary Zhang, and Li Huaide standing there, along with seven or eight workers, all of whom looked to be in their forties.

"Chief Engineer Li, let's skip the formalities."

Factory Director Yang got straight to the point, "The higher-ups were very satisfied with the batch of work you did before. This time, they've given our factory a new job, with a tight deadline and a heavy workload."

He pushed the blueprints and fifty workpieces in front of Li Weidong: "We need to deliver them before dawn. Do you think you can handle them?"

Li Weidong took the blueprints and flipped through them, his face remaining expressionless. After two or three minutes, he nodded: "The work isn't difficult, but this thing requires a high level of precision."

"The workpiece has high hardness, and the precision must be controlled within two levels."

Li Huaide added from the side, "The shape is also very strange..."

"This is a part used in the 940 engine of the aircraft."

Li Weidong casually added a comment.

"Chief Engineer Li!"

Factory Director Yang's voice turned stern, his tone carrying a warning.

Li Weidong paused for a moment, then came to his senses. It was the 1960s, and everything done in the factory was subject to secrecy regulations. Taiwan was still clamoring for a counter-offensive, and there were many spies secretly operating on the mainland.

I spoke out of turn.

Li Weidong smiled somewhat awkwardly.

"It's not entirely your fault."

Factory Director Yang sighed. "You're not from a professional background; you learned the technology on your own without any confidentiality training. I'll give you more pointers in the future. There are some things you should keep to yourself; don't say them out loud. That's our duty as industrial workers."

Secretary Zhang then spoke up: "Alright, everyone here today is an elder, you all know what's going on. Let's pretend we didn't hear what was said earlier."

"Yes, yes, I didn't hear it, I didn't hear it."

Several workers quickly echoed this, their faces displaying knowing expressions. The less you know, the less trouble you'll have.

Factory Director Yang, being a veteran Party member, was highly vigilant. He frowned at Li Weidong: "The blueprints don't even specify what kind of component it is, how did you figure it out at a glance?"

Li Weidong rubbed his nose, somewhat helplessly: "I could tell. This kind of old engine model... never mind, I won't say anything more."

"You call this engine outdated?"

Factory Director Yang's eyes widened, and he no longer cared about keeping it a secret. "These are parts from active-duty aircraft. We took this job for repairs..."

"Fine, fine, if you say we won't fall behind, then we won't fall behind."

Li Weidong shrugged.

The little bit of information in Li Weidong's mind was entirely supported by his 55 mental strength, like a large hard drive filled to the brim.

"Process the parts first, we can talk about some things later."

Factory Director Yang stared at Li Weidong for a couple of seconds, his eyes filled with a hint of incomprehension.

Li Weidong knew perfectly well that the other person's gaze held suspicion.

No wonder, he can even talk about airplane engines so fluently, who wouldn't be suspicious? But to say he's a spy sent from over there doesn't seem to be one—if he were really a talent, who would be willing to put him here?

Li Weidong remained calm and secretly rejoiced that his body had a good habit.

When I was in medical school in Guangzhou, I not only studied Western medicine, but also learned traditional Chinese medicine from an old Chinese medicine doctor. In my spare time, I would work odd jobs at a steel rolling mill and draw a lot of blueprints. At the time, my classmates couldn't understand them and thought those blueprints were mysterious.

Actually, those were just the basics; the blueprints were eventually sent to the toilet, where he treated them as waste paper.

But if someone digs it up now, it will perfectly explain why he's so amazing.

"Director Yang, let's not wait until later, let me just say it."

Li Weidong said casually, "I did some design work on fighter jet engines in medical school, but it was all just drawing on paper."

"So I understand these things at a glance."

Everyone present stared wide-eyed, and Factory Director Yang's voice trembled: "You...you designed engine blueprints? And you say this thing is outdated?"

"Hmm, I'll make one myself when I have time."

Li Weidong said, "It's just that some materials are not easy to obtain."

"Easy, easy!"

Secretary Zhang was so excited he slapped his thigh, "Whatever you want, the factory will find a way to get it for you, even if we have to steal it!"

"We'll talk about that later. Let's get this batch of stuff out first."

Li Weidong turned to the workshop director, "Director Zhou, why aren't Engineer Ding and Engineer Chen here?"

Director Zhou paused for a moment, then said, "They're both level seven workers..."

"Don't worry, we'll take this opportunity tonight to teach them a lesson and give them a push."

Li Weidong said with a smile, "I'm going to take the Level 8 worker exam next Monday. If I perform normally, I'll definitely get two Level 8 worker certifications."

As soon as these words were spoken, not only Director Zhou, but also Factory Director Yang and the others beamed with joy.

"I'll go get them right away!"

Director Zhou called out, "They're nearby, a ten-minute round trip."

After saying that, he pedaled his bicycle and sped off.

Just then, Yi Zhonghai walked in.

"I'll process one workpiece first, so everyone can take a look."

Li Weidong said, "I'll explain it to everyone when Engineer Ding and Engineer Chen arrive."

"The accuracy requirement is within one pass, and my standard is also limited to one pass."

One line is 0.01 millimeters.

"This...we can't do it."

An experienced craftsman said with a bitter face, "Being able to get stuck on one line is already the limit, let alone inside one line... It's impossible."

The veins on Yi Zhonghai's forehead throbbed, his face turned purplish-red, and he swayed, almost falling to the ground.

Li Weidong had previously said that Yi Zhonghai was a shoddy, substandard worker. This rumor had already spread throughout the workshop. Now, in front of so many people, the kid repeated it again.

Secretary Zhang quickly tried to smooth things over: "Weidong, your idea is good, but you can't use your own freakish standards to judge others. Our factory's level eight workers are all properly certified through rigorous examinations. Even if their skill levels vary, everyone is still..."

Before he could finish speaking, Director Yang grabbed him.

Secretary Zhang was taken aback, then realized that Director Yang was afraid that if he said anything, he would be humiliated later.

Yi Zhonghai's level eight worker title wasn't earned through exams at all. Back then, he was just a level seven fitter. He happened to work on a part in front of a leader, who, in a moment of pleasure, promoted him a level. Later, that leader died, and only then did Yi Zhonghai quiet down a bit. In the years before that, he was practically swaggering.

Li Weidong ignored them and went straight to his workstation.

Turn on the machine, load the workpiece, perform a rough cut first, then slowly work it by hand. The whole process takes about the time it takes to eat a meal, and a piece is finished.

Throughout the work process, he unleashed his full mental power, coupled with his master-level martial arts foundation, making every muscle in his body obey his commands. He could be fast when needed and accurate when required.

"Alright, everyone's here."

When Li Weidong looked up, he realized that Director Zhou, Engineer Ding, and Engineer Chen were already standing in a circle.

"Then I'll slowly finish one more."

Li Weidong adjusted his posture. "Let me explain to you how to improve precision. There are a few tricks. What used to be controllable within two steps, can now be controlled within one step using this method."

Yi Zhonghai stepped forward, a concerned expression on his face: "Chief Engineer Li, this piece hasn't been inspected yet. It's not certain whether it will pass inspection."

When Li Weidong gets to work, he doesn't use measuring tools to measure the parts at all. This is completely different from other technicians. Even those experienced masters measure as they work, afraid of being off by even the slightest bit.

"Master Yi, bring your micrometer over here and measure the precision."

Li Weidong's lips curled slightly, his tone carrying a hint of provocation.

Yi Zhonghai originally wanted to slap Li Weidong hard in front of everyone. But now, he felt like he had offered his face up and been slapped hard.

He felt a surge of secret delight, utterly disbelieving that anyone could control the tolerance to within one notch without taking measurements. This job wasn't like working on an engine or an electric fan; a little error in those things wasn't a big deal, a few notches wouldn't be a problem.

It's not difficult to increase the precision to five lines, but to push it up by one line from five lines requires ten times the effort.

All eyes were fixed on the micrometer in Yi Zhonghai's hand. He took a few measurements, his mouth opened wide, then his eyes widened, and he hurriedly measured it again.

"Master Yi, you're a level eight technician, why are you dawdling over measuring something?"

Li Huaide frowned and urged, "Hurry up and give us a number!"
