A nation's industrial development begins with junior engineers.

Let's not even mention Director Yang's sob story at the First Ministry of Machine Building.

Jiangxia got up early in the morning, ate a few steamed buns, and then took the "five pillars" to the repair workshop.

Workshop director Du Changyuan received a notice from factory director Yang early in the morning, instructing him to fully cooperate with Jiangxia.

Du Changyuan was very cooperative with the order. He took the blueprints and instructed his colleagues to start making them according to the requirements.

It was just a simple water tank and connecting device, so Jiang Xia didn't need to be watching over it.

Jiang Xia led the "Five Pillars" to an unused fitter's workbench, where they began to tinker with "a concept based on using atmospheric pressure to lift groundwater."

To put it simply, it's a hand-operated pump well.

The things that will become commonplace in later generations are currently a blank slate.

Hand pump wells, also called hand pump wells, were once the kind my grandmother lived in before crossing Jiangxia.

When I was a child, I was always curious about why well water would keep flowing out when you poured some water in and pressed the pump a couple of times.

As he grew up, Jiang Xia did some serious research on it.

Discovering this hand pump well was a great relief.

When Jiang Xia was feeling down, he liked to go there and pump water. He could play like that for an entire afternoon, splashing and gurgling.

Of course, a scolding was inevitable afterward. What a waste of water!

Jiang Xia pulled out another blueprint and began to explain the "five pillars" in detail.

This thing is simple; it's just a well shaft, a piston, an external water inlet valve, and a check valve.

Besides the fact that the one-way valve needs to be assembled with the piston to form a vacuum in the wellbore, which requires a certain degree of precision.

The rest is nothing special.

After explaining the production method and steps, Jiang Xia prepared to negotiate with the director of the second workshop about borrowing the "five pillars".

That's right, Jiang Xia added the names of all five pillars to the water pump experiment group.

You have the right to use it and it will become invalid upon expiration.

In any case, Jiang Xia didn't want to see his nephews doing the hard labor of unloading goods.

The five pillars of the Jiang family were all skilled craftsmen. In addition, having worked in the steel rolling mill for so many years, they were adept at simple fitter and welder tasks.

It's their status as temporary workers that's holding them back. If they had legitimate worker status and participated in the evaluation and assessment, they might not get a level 5, but getting a level 2 or 3 would be no problem.

"Oh, so the college student's showing off in the factory again?"

"Look at this blueprint! It's a perfectly good water tank, and you've dug a hole in it. Isn't that a waste?!"

Unfortunately, as Jiangxia was heading out, he encountered a young man who made a few sarcastic remarks.

Hey, you think you're so great?

Jiang Xia recognized the man; wasn't he Master Jia's apprentice?

In the workshop, Jiang Xia always had the face of a kind-hearted college student. They just ate rice from the big pot, getting all burnt and scorched – it was all for nothing.

But he's not a hundred-yuan bill; not everyone can like him.

However, as long as it's something that most people like, that's fine.

"Hey, that's strange. You, Jia Dongxu, are just a first-level fitter. Where do you get the audacity to question someone else's level 9 engineer?"

"Instead of wasting time spouting nonsense, why don't you take a Level 2 exam and show us when it's time for the evaluation?"

"Young lady, how long did it take the master chef to teach you, and you still can't pass the Level 2 exam? What a waste of that opportunity!"

A middle-aged man, carrying a welding rod, glared at Jia Dongxu menacingly. Behind him, a group of young people unleashed a barrage of sarcastic remarks at him.

"Hey, you can't insult someone by bringing up their weaknesses. You guys are just being unreasonable!"

"Is it because Xiao Jia doesn't want to pass the exam? It's because the teaching is inadequate!"

"Hey, Xiao Jia isn't good enough. But other people have beautiful wives, do you? If you were replaced by Xiao Jia, you probably couldn't even lift a file!"

The workers standing nearby seemed to be trying to mediate, but their words were so hurtful.

Hearing the commotion, the five pillars immediately ran over and stood behind Jiang Xia.

The cold glint in his eyes made Jia Dongxu retreat repeatedly.

The master mechanic in the repair shop looked at his apprentice, who seemed to have been taken advantage of.

He strolled over slowly: "Hey, what are you all doing! Don't you have much work today? Are you all just gathering here to get paid?"

"Liu Yongfu, aren't you going to control your apprentice?! If you want to cause trouble, go back to your workshop! Our maintenance workshop doesn't welcome you!"

Liu Yongfu toyed with the welding rod in his hand. "What, Yi Zhonghai, you've become the workshop director? You're like a toad trying to show off your big mouth!"

"You're allowed to have your apprentice making a racket there, but we're not allowed to rush back? Just because you're a level 8 worker who can't even make a proper rolling mill?"

Yi Zhonghai nearly spat out a mouthful of blood: "Who is it! Who is it! Don't you dare slander my cooking skills!"

"Besides, we weren't talking about you guys, so why are you causing trouble?"

Hearing Liu Yongfu say this, Jia Dongxu's face turned pale.

I heard about this from the people in Workshop 3 yesterday.

He knows his own business best. He was in charge of making a batch of rolling mill rolls.

The lathe operator handed the finished parts to his master, who then handed them to him.

According to procedure, he should have made further refinements based on the blueprints.

Jia Dongxu was being lazy at the time. He thought the rolls were quite straight, so he just pretended to make a few cuts on them. The quality control department didn't inspect them carefully afterward, and they were all put into storage.

Intuition told Jia Dongxu that the problematic roller might have come from his work!

Liu Yongfu spat: "Show me your skills. How did you get this level 8 craftsmanship? Should I inform you?"

"We've been working overtime for so long just for a few rolling mill rolls!"

Seeing that Yi Zhonghai was somewhat embarrassed, Jia Dongxu's eyes darted around, and he quickly changed the subject: "Oh dear, oh dear. We're talking about the blueprints! How did we get involved with my master! Don't you think there's something wrong with the blueprints?"

Seeing that the argument was about to go off track, they finally steered it back to their own point of view.

Jiang Xia remained calm: "Comrade Jia Dongxu, before you blame me, shouldn't you carefully check if you've picked up the blueprints upside down?"

Upon hearing Jiang Xia's words, Jiang Wuzhu darted out from behind him.

He gripped Jia Dongxu's hands tightly, which were holding the blueprints: "Kid, don't move! Let everyone see how you got those blueprints!"

Jia Dongxu was startled; he couldn't understand a thing's blueprints. Usually, Yi Zhonghai would look at the blueprints and then teach him how to make them.

Today, he was in the workshop again, watching Jiang Xia. His mouth was itching to talk about the victory he had last time.

That's just blatant nonsense.

Before Jia Dongxu could struggle, his coworkers rushed over.

"Oh my god, he really picked it up backwards! The requirements for the drawing are all marked in the lower right corner, but Jia Dongxu just read the words backwards!"

"Nonsense! The blueprint requirements don't say anything on the right! Aren't they all on the left?"

Liu Yongfu looked at Jia Dongxu as if he were trash.

"Jiang, the technician—no, I mean, Engineer Jiang, haven't you looked at the drawings?"

"Tsk, I forgot you're a first-class worker, you're not qualified to work on Engineer Jiang's blueprints at all!"
