A nation's industrial development begins with junior engineers.

Yi Zhonghai dragged his tired body through the gate of the courtyard house.

He was accompanied by a talkative Jia Dongxu.

"Master, it's just a cylinder, how many have we made this afternoon? That technician still won't approve it. I think she's just deliberately making things difficult for us!"

"Master, do you think it's Jiang Xia...?"

"Making things difficult?" Yi Zhonghai glanced at Jia Dongxu, who was muttering incessantly, and couldn't help but speak up: "Dongxu, you should pay more attention. This is obviously a big project for the factory, an opportunity that others would kill for. How did you manage to mess it up?"

"I told you to start with 40 grit, then move on to 120 grit, and only then can you use 180 grit. But you went ahead and skipped 120 grit! What are you trying to save on? Does the factory need a few more pieces of sandpaper?"

"Besides, what does this have to do with Jiang Xia? Hey, tell me, why are you always picking on him?"

Jia Dongxu shrank his neck: "It's just that the wrong sandpaper was used. Anyway, it looks pretty smooth."

Upon closer inspection, Yi Zhonghai still had a stern face, while Jia Dongxu obediently admitted his mistake.

"Master, I was wrong. I will definitely do as required next time."

Upon hearing this, Yi Zhonghai's anger surged again. Next time? Will there ever be a next time?

Thinking of that closed door, Yi Zhonghai felt a sudden, inexplicable sense of panic.

"As for Jiang Xia, I just can't stand him! He's always hanging out with Liu Yongfu! And Liu Yongfu is always talking badly about you!"

"Nothing else..."

Hearing Jia Dongxu's words and looking at Jia Dongxu's upright face, Yi Zhonghai's hardened heart softened again.

The child is still filial. It's just that the filial piety has been misplaced.

Well, after all, I've raised this child for over ten years.

"Alright, Liu Yongfu is Liu Yongfu, and Jiang Xia is Jiang Xia. Master is an eighth-grade worker, so he's not afraid of those gossips."

Let's put in some effort tomorrow and stop slacking off. Then we'll both be wearing big red flowers and standing on the podium!

"Alright, Master!" Jia Dongxu raised his eyebrows and became cheerful again.

It turned out that Yang Youning had gathered the main workforce from all the workshops at noon. Not a single level 8 worker in the factory was left out.

They were all crammed into the newly established "Water Drilling Machine Project Department".

The well drilling machine was also disassembled into two sets of blueprints.

The drilling rig is nothing special; it's just a regular drilling rig. It's a drilling tower with drill pipes, and the hoisting system was simplified to a screw-type system by Jiang Xia. The mud circulation system was completely eliminated by Jiang Xia.

Since it's a small-diameter well anyway, we can just pull it out and shake it a few more times.

We already had drill bits readily available; we made a batch two years ago, intending to send them to an exploration team in the north. However, they weren't interested, and we ended up with them sitting unused. Now they come in handy.

As an aside, this batch of drill bits is exactly the first test product that Li Huaide is preparing to use in production management.

After his efforts were thwarted, Yang Youning immediately labeled his attempts at production as haphazard and cut them off.

The other set of blueprints was quite extraordinary; the basic requirement for participation was a level 6 worker. Before even looking at the blueprints, Wang Kui, with a cold expression, made everyone sign a confidentiality agreement.

The blueprints were even divided into individual parts.

Apart from the basic dimensions and acceptance criteria, all other parameters were blacked out. The drawings weren't even assigned to the master craftsman.

Instead, you can choose whatever parts you feel your craftsmanship meets.

Yi Zhonghai was a veteran of the Hongxing Steel Rolling Mill, and he had only encountered this kind of situation twice before. It was clearly a great opportunity, the kind that would bring prestige to anyone who joined.

So they chose the component with the second highest requirements – the cylinder.

After the selection was made, he even managed to get Jia Dongxu included by virtue of his status as an 8th-grade worker.

Yang Youning and the others had no objection to this; an apprentice at the level 8 level should still have some skills. Besides, the factory had a tradition of experienced workers mentoring newcomers.

I made three in one afternoon, but the first two were scrapped for various reasons.

After going through numerous inspections, the last step was the fine machining and polishing of the cylinder inner wall.

After a tiring afternoon, Yi Zhonghai finally couldn't take it anymore.

So they called Jia Dongxu to polish it, but who would have thought that this kid didn't understand the situation and actually cut corners at this time.

This resulted in the cylinder that came closest to the standard being directly labeled as defective.

There's nothing I can do; Yi Zhonghai is simply too exhausted to continue today.

So he took Jia Dongxu home from work.

As Yi Zhonghai walked out of the small workshop, he looked back and realized that he was the only one leaving get off work; everyone else was still busy.

After taking a few steps forward, Yi Zhonghai instinctively felt that something was wrong and turned around to go back to the small workshop.

However, they were stopped by the security guards at the entrance, and the door to the small workshop was tightly closed.

With a smile on his face, Wang Kui came over and reiterated the confidentiality policy to him.

On his way home, Yi Zhonghai suddenly realized that he might never be able to get through that door again.

As he entered the courtyard, Yi Zhonghai decided to put all that aside for now; after all, his belly was the most important thing.

He was so hungry he was nauseous, so he decided to go home and find something to eat.

But as soon as he passed through the hanging flower gate, he saw an old woman looking at him with a panicked expression:

"Old Yi, you're finally back! Sha Zhu's been arrested!"

"Arrested?" Yi Zhonghai and Jia Dongxu asked in unison.

Yi Zhonghai looked utterly astonished, while Jia Dongxu was a mixture of confusion and excitement.

Yi Zhonghai rubbed his stomach, which helped to alleviate his hunger, and looked at the older woman: "What happened? Didn't you say you were going to help Sha Zhu find a partner today? How come you got arrested on a blind date?"

"Who arrested him?"

An old woman waved her hand angrily: "It's all because of that Xu Damao! I brought that girl to the yard this morning, and Xu Damao suddenly appeared out of nowhere and said a bunch of bad things about Sha Zhu to the girl."

"What did he say? Sha Zhu's dad went to help out, and even said that the rain was hard to handle. That made the girl angry and leave."

"Later, when Sha Zhu found out, he immediately started fighting with Xu Damao."

"As a result, we ran into two police officers and were detained."

Yi Zhonghai frowned: "Why are there police officers in the compound?"

"Hey, stop worrying about that. Hurry up and get Sha Zhu out! Don't forget his dad entrusted his two siblings to us!"

Upon hearing this, Yi Zhonghai wanted to set off, but he was so hungry that he felt like there were several mice gnawing at his stomach.

"Dongxu, go check with the police station up ahead. How did these two young men get arrested for a fight?"

Jia Dongxu's smile immediately turned into a crying face: "Master, I'm starving too. Why don't we eat something before we go?"

Yi Zhonghai thought for a moment, then took out a dollar and gave it to Jia Dongxu: "This matter could be big or small. Take this money and grab a bite to eat on the roadside. The most important thing is to find the person first."

Perhaps because it's still early, Jia Dongxu hasn't been posted online yet. Yi Zhonghai's idea of ​​finding someone to care for him in his old age isn't quite so extreme yet; his current behavior is still relatively normal.

In this day and age, there are still areas where the powers of different departments overlap.

Once the police arrest someone, they might take them directly to the station, hand them over to the local street office, or even end up in the factory's security department.

Therefore, to rescue someone, you need to determine the location first before you can make any effort.
