Siheyuan: Craftsmen of a Great Country

After returning home, Shangguan Wan'er looked at the familiar people and things and sighed, "Home is still the best!"

"Aunt Zhang, everyone, I'm back!"

Liu Yue, Luo Xue and Shangguan Yuer all greeted them with a smile.

Only Zhao Qi was still in the Pyramid Country and not at home.

She is the only one among the girls whose mother wanted to add a surname.

Zhang Cui looked at Shangguan Wan'er and said, "Wan'er, you're back. Look at you. You've lost a lot of weight. You must have suffered a lot outside!"

Shangguan Wan'er said: "It's not hard, it's not hard. Others treat us like treasures, how dare they let us suffer."

The actual situation is definitely not as easy as she said.

These days, it’s impossible not to suffer when you go out.

Especially since Shangguan Wan'er is still a girl.

Food, housing, clothing and daily necessities are all problems.

In many places, not only are the living quarters dirty and messy, but even taking a shower is a problem.

The food is slightly better.

Now there are clear requirements for workers' diet, and the supply is basically guaranteed.

When they went there, the factory would treat them with the best of everything they had.

After all, this converter has a lifespan.

Once the life span is reached or it is damaged, they have to come and repair it.

Besides, if the team pays a little more attention when they come to inspect, it is possible to avoid a production accident.

But many other facilities are beyond the control of the factory.

For example, this slow and hot green train.

This long journey is so uncomfortable.

Fortunately, before they started construction, they planned the route in advance based on the distribution map of the Ministry of Industry.

Carrying out converter construction in an orderly manner can reduce the time wasted on the road and avoid long-distance trains to the greatest extent possible.

In the past six months, Shangguan Wan'er has really suffered a lot.

But she gritted her teeth and persevered.

Because she knew that she did not have Luo Xue's talent for precision, nor did she have Liu Yue's outstanding management skills.

If you want to become Jiang Chen's helper, gain everyone's recognition and gain a firm foothold, you have to endure more hardships and make up for the gap with hard work.

She herself overlooked the fact that her extraordinary learning ability was actually a talent.

And it is a very useful talent. Now she is still young and has just started working, so its effect is not very obvious yet.

But as she works more deeply, her advantages will become more and more obvious.

By then, she and Luo Xue, one a scholar and the other a warrior, will become the greatest assets of the Seed Institute.

Zhang Cui snorted: "When Xiaochen arranged for you to do this, I was firmly against it."

"There's chaos and disorder outside. How can we arrange for such a beautiful girl to run around everywhere? He is relieved."

"If something unexpected happens, I will regret it for the rest of my life."

Liu Yue smiled and explained: "Mom, don't worry, the boss will never let Wan'er run around alone, he has already made arrangements!"

"The teammate next to Sister Wan'er is a female security officer from the security department. She is very skilled. Sister Wan'er's safety is definitely guaranteed!"

Shangguan Wan'er was stunned: "Ah? There is such a thing, how come I didn't know anything about it."

Zhang Cui also looked at Jiang Chen in confusion.

Jiang Chen nodded: "Well, she is indeed from the security department, but this is a test for her by the security department to see if she has the ability to complete the security mission without being discovered."

"So, I didn't tell you. Xiaoyue knew because she is the manager and your eldest sister, so I told her."

"Otherwise, I'll let Yu'er go with me."

Shangguan Wan'er was stunned: "Is she so powerful? I didn't realize it at all!"

She was a little touched.

It turned out that Jiang Chen had already thought of everything.

Jiang Chen nodded: "It's really amazing. She only took three days to learn about converter steelmaking and other related knowledge, and she mastered it quite well. She can be considered a person of outstanding talent."

"Of course, compared to Wan'er, this monster, it's still a long way behind."

Shangguan Wan'er snorted: "You are the evildoer."

Zhang Cui snorted: "Even if someone protects her, it's useless. Don't you see how much suffering Wannu has gone through along the way?"

Jiang Chen changed the subject: "Okay, let's eat first."

"Wan'er must be hungry after a long journey."

Shangguan Wan'er nodded: "I am indeed a little hungry. Thinking about the evening gathering to taste Sister Yue's cooking, I didn't even have lunch."

Shangguan Yuer said: "Sister Yue's cooking skills have improved a lot. Now I basically don't eat at home. I come here every day to eat for free."

Jiang Chen said unhappily, "You are so thick-skinned that you dare to say that."

"When you get your salary next month, give half of it to me as food expenses."

Shangguan Yuer snorted: "Just hand it over."

Zhang Cui said angrily: "She is your sister-in-law after all, how dare you accept her?"

Jiang Chen said: "It is only natural to pay for meals. Why should I be embarrassed to collect it? It's good enough that she can come to eat."

Because Wan'er was coming back, the dinner was especially sumptuous.

The family ate and chatted happily.

After dinner, the girls finished cleaning up and sat in the living room chatting.

Shangguan Wan'er shared some interesting things that she encountered outside, which made the girls marvel.

Liu Yue and Luo Xue also talked about the current situation of Sijiu City and the Seed Institute.

When everyone had finished chatting, Jiang Chen lit a cigarette and said slowly, "Okay, let's stop chatting for now."

"Xiaoxue, Wan'er, let me tell you about your future plans."

When it came time to talk about business, the women all sat upright.

Although Zhang Cui felt that Wan'er had just returned and was talking about work in a hurry without even taking a rest, she did not speak to stop her.

Jiang Chen said: "You want to talk about Xiaoxue!"

"Xiaoxue has a natural advantage in precision work and micro-manipulation. Your subsequent work will still start from this aspect."

Luo Xue was stunned: "Ah? But I feel that the IT5 precision machine tool has reached its limit. I don't think there will be much progress if I continue to study it."

“And this is already the most accurate machine tool in the world.”

Jiang Chen said calmly: "Do you know why it is IT5 level instead of IT1?"

Luo Xue said: "It means there are 4 levels with higher precision."

In fact, this level of precision tolerance is proportional to the basic dimensions of the parts.

However, when Jiang Chen and others discussed this basic point, they verified it with the highest accuracy.

In other words, IT-level processing accuracy can reach 5 microns.

Jiang Chen: "That's right. This shows that the research of this work is far from reaching its limit, and you haven't reached your limit either."

"What I need you to do is to increase this accuracy by a thousand times."

Luo Xue was stunned: "A thousand times, even if I work myself blind, I still can't do it."

One thousand times is 5 nanometers.

If you are not an industry insider, you may not have even heard of the unit of nanometer.

Not only Luo Xue, but even Shangguan Wan'er and Liu Yue were equally stunned.

Zhang Cui and Shangguan Yuer, who don't know much about this, are slightly better off.

Jiang Chen smiled and said, "No, you have to believe in yourself, you can do it!"

"What you have achieved now is only the limit of machine tool production based on the existing technology. When the industrial foundation catches up in the future, you will still have a lot of room for improvement."

Luo Xue said: "Leader, you also said it is in the future."

Jiang Chen said: "But you forgot, I just said that the limit of machine tool production is not the limit of precision."

“So, we have to change the track.”

Luo Xue asked: "What track?"

Jiang Chen uttered three words lightly:

"Lithography!"
