Siheyuan: Craftsmen of a Great Country

After returning home from get off work, Jiang Chen, who had once again increased his physical fitness, felt no discomfort at all.

But Liu Yue felt a little dizzy.

Listening and learning at the same time is indeed not easy.

Her foundation was already weak, but if she participated in the research and development process, terms that she had never heard of would come flooding in, and her little head would almost explode.

She looked at Jiang Chen with admiration: "Leader, you are only 20 years old, how do you know so much."

Jiang Chen pointed at the bookshelf that was moved from Luo Xue's house behind him: "If you were like me and had been reading books since you were literate, for more than ten years, you would understand so much."

There were already a lot of books on the bookshelves, and with Jiang Chen's own books, they were already filled to the brim.

Liu Yue curled her lips: "Forget it, I'm not good at studying, and now my foundation is too poor to make up for it."

"I'd better be the woman behind you, cooking for you, washing your clothes, and giving birth to your children."

Jiang Chen smiled and said: "Then you have to be prepared. It's not easy for the things you said."

"Especially when you are raising a baby, you will poop and pee, cry and fuss, and you have to drink milk within three or four hours at night, which will make you collapse."

Liu Yue said: "I don't know how. I really like children. When I was in the orphanage, I took care of the children who just came in."

Jiang Chen said: "Oh, do you have work experience?"

Liu Yue smiled and said: "That's right, leader, when are we going to have a baby?"

Jiang Chen was stunned: "You're not even old enough to get married yet, and you're just thinking about your children! What, are you anxious?"

Liu Yue shook her head: "I'm not anxious, I'm just thinking about it."

Jiang Chen pondered for a moment: "Let it go as it comes! But you have to be mentally prepared. Pregnancy is not easy for our Jiang family. My ancestors have been passed down alone for six generations."

"If you want kids, we have to work harder."

Liu Yue's face turned red and her heart trembled: "Ah? Why is this happening?"

She also wanted to work harder, but her body didn't allow it and she just couldn't bear it.

Thinking of last night, her legs felt weak.

Love and fear at the same time, this is probably the case.

Jiang Chen shook his head: "I don't know, maybe it's genes!"

This is not because Jiang Chen is lying, but because their lineage is really like this.

My mother has said a long time ago that it is unknown when she will have a child. For example, she gave birth to Jiang Chen in less than a year. Everyone said that smoke was coming out of the ancestral graves and high incense was burned.

So Jiang Chen had better get married early and work hard.

Scientifically speaking, this is a chromosomal abnormality. As for the cause, Jiang Chen doesn't know.

Perhaps there was a genetic mutation in our ancestors that caused difficulty in pregnancy, and it has been passed down.

Although he is a time traveler, this body belongs to someone else.

I just don’t know if the system will fix this for him when he increases his physique.

After dinner, the two chatted for a while and then prepared to rest.

Liu Yue took the initiative to take out a cigarette and light it for Jiang Chen.

Seeing Jiang Chen's confused look, she looked around and said to him: "You look so handsome when you smoke!"

Jiang Chen glanced at her sideways: "Be more careful with your hands!"

"Woman, you are playing with fire!"

Liu Yue's eyes were as charming as silk: "After smoking, let's work hard!"

Jiang Chen said: "Are you sure you can do it?"

Liu Yue nodded firmly: "I can!"

Jiang Chen hooked his fingers: "Then why do you have to wait for the cigarette to finish smoking?"

Two hours later, Jiang Chen entered the space.

I can't see a thousand mission points. With the current consumption of four points an hour, I can't support it for a month.

I thought to myself: This mission cycle is relatively long, and the mission points are a bit out of supply. It seems that in the future, we should not waste time entering the space when it is not necessary.

He reviewed the machine tool development information again, and after making sure that nothing was missing, he exited the space and fell asleep holding Liu Yue in his arms.

This was the first time he really slept since he arrived in the courtyard.

The heated kang and the warm jade in my arms are also a kind of enjoyment.

In the following time, Jiang Chen devoted all his time to the development of machine tools.

They discussed and tried to make one by conquering it one component at a time.

While the workers worked, others stood and watched.

And promptly put forward their opinions and ideas to ensure that the parts are produced according to the previously discussed plan.

At the beginning, these arrogant senior workers didn't like this method very much.

But they gradually got used to it, and they found that this method of communicating while producing could effectively shorten the cognitive bias that may occur during the trial production of parts and make research and development more efficient, so they said nothing more.

After the component passes the inspection, the next component can be researched and discussed.

With Jiang Chen's guarantee, the progress is not too slow.

This afternoon, there was a burst of cheers in the warehouse.

Qin Kai sighed sincerely: "Luo Xue, you are great."

"How about it? I'll say that it can be produced according to these parameters."

During this period, Qin Kai finally recognized Jiang Chen and integrated into the team.

Jiang Chen's impression of him also changed.

Although this person does not have a broad view of the overall situation and his thinking is not flexible enough, he has good theoretical knowledge and basic skills.

He can always put forward some reasonable opinions when workers are producing parts.

After each part is produced, Wanli will draw a comprehensive and multi-angle diagram based on the data of the part.

It is clear and concise, as long as you get the schematic diagram, you can basically follow it for production.

The most difficult part, the transmission, was the first part to be completed, and it was much smoother than expected.

After all, after explanation and discussion, this transmission device is actually a collection of dozens of parts.

After being produced and assembled together, the original form of the transmission device is formed.

Starting from the first component, Jiang Chen's requirements were relatively strict.

The module, pressure angle and number of teeth have all been clearly defined, and no deviation is allowed to exceed the error range.

If you want to standardize, this is the most basic thing.

Just now, we encountered a problem when producing a part with relatively high precision requirements.

Everyone has tried it, and using existing tools, no matter how hard they try, they still cannot achieve the predetermined accuracy.

Finally, Luo Xue, who was not a worker, proposed to give it a try, and successfully accomplished it in front of everyone's disbelieving eyes, which immediately aroused everyone's amazement.

Another difficulty was overcome, and the others were also excited and generously praised:

"I didn't expect that Luo Xue was able to handle something that even our group of professional fitters couldn't handle."

"I just said that for such delicate things, we still need to rely on lesbians, who are more dexterous."

"Indeed, we old men can't do such a delicate job. Liu Yue was just a little bit behind, and Luo Xue is completely up to standard."

Luo Xue looked arrogant and pretended to be humble: "I just gave it a try. Fortunately, I studied the techniques carefully during the previous training."

Jiang Chen smiled and said, "Well done."

He discovered another thing about Luo Xue

Then he clapped his hands to signal everyone to be quiet.

After everyone calmed down, Jiang Chen said: "The difficulty has been overcome, but have you discovered any problems?"

Everyone was stunned.

Qin Kai said in confusion: "Isn't it a good thing to be able to overcome difficulties? Why are there still problems?"

When discussing it before, he repeatedly insisted on high precision. Under the temptation of high efficiency, many people supported giving it a try, and that was why he made the subsequent attempt.

Jiang Chen said: "High-precision requirements can indeed slightly improve the performance and energy efficiency of machine tools to a certain extent."

"But have you ever thought about it, that several of our eighth-level workers, plus two young workers with outstanding talents, are unable to manufacture parts with such precision under the current conditions."

"So, what about the production after the machine tool is developed? How many people like Luo Xue can we find to complete the production of this part?"

"If this part cannot be mass-produced, our machine tools will only remain in the experimental stage without any practical significance."

actually in

After listening to Jiang Chen's words, everyone understood instantly.

Passing it in the laboratory does not mean it can be mass produced.

The precision requirements of machine tools slightly exceed the industrial base of flower growers, but workers can produce it if they are more careful.

But if it exceeds too much, it will cause production difficulties, making the machine tool unable to mass-produce, and even if it is forced to produce, the output will be extremely low.

Jiang Chen continued: "So, when necessary, we cannot abandon the current industrial base and pursue perfection too much. That is just being a hooligan."

"Only when our batch of machine tools becomes popular, the production precision will be high. When the next batch of machine tools are developed, we can pursue higher precision."

"Industry is like this, you can only take one step at a time. If you want to develop by leaps and bounds, you need to import a complete industrial chain, which is something our country simply cannot afford at the moment."

"Okay, adjust the parameters, even if you sacrifice a little performance, you must ensure that the machine tool can be mass-produced."
