Ye Hui's question made Xu Chunhai stunned in place unimaginably.

Draw it out? Unless the machine is completely disassembled, one component at a time to draw.

In the previous life, it is not that no one has studied it, and this kind of machine tool with minor injuries will have such and such problems after a few years of use.

If there is a problem, there will be a special master to deal with it, from the initial helplessness to the subsequent familiarity, all rely on the accumulation of time.

He remembers that at that time, after the machine tool of a research institute was completely scrapped, there was a special team to disassemble the machine tool for drawing.

However, this is not a trivial matter, and the dimensions of each part, the materials used and the nesting techniques need to be studied slowly.

And in the end, it was found that there were several key components that could not be produced at all because of the lack of precision machine tools in China.

Precision machine tools are something that is held down by Midi and other developed countries, and they will not be sold to them at all, so although I feel regretful later, it is still gone.

When he thought about his past life, he was extremely depressed.

"Sister, it's not a question of whether it can be replicated, it's that we don't have the ability to produce many components."

No matter how in-depth it is, it is not suitable to talk about it on such an occasion, Ye Hui snorted, "Okay, I know." ”

She didn't know much about mechanical manufacturing, and she didn't have the experience of going abroad with a group in the last two years of college.

She asked Xu Chunhai to help her, and worked hard to sweep the machine again, this time she gritted her teeth and barely fainted until she got into the car back.

When she woke up again, she was already in the bed at home, and Hei Xi slept next to her, her small hands clenched into fists and fell to her mouth, and her face seemed to have traces of crying.

Seeing that she was awake, Cao Yanhua, who was guarding her, put down the newspaper in her hand.

"Are you hungry? I've got rice hot in the pot, do I want to bring it to you? ”

Speaking of eating, Ye Hui immediately heard a gurgling sound from her stomach, and she quickly nodded.

"Is Harumi here?"

"Yes, I didn't leave after sending you back, I'll help you call him."

Knowing that the two sisters and brothers had something to say, Cao Yanhua was not curious at all and went back to her house after setting up the meal.

Just before going out, I told her that Xixi was afraid that she was going to wake up, and asked her to pay more attention to the movements in the house.

"Eldest sister, why do you faint again and again?"

Xu Chunhai is not stupid, once it is an accident, and twice is definitely not an accident, combined with what Ye Hui said today, he always feels that he is close to something that he dare not think about.

Ye Hui ate dinner quickly, Cao Yanhua knew her amount of food very well, and there were five or six big steamed buns on the plate.

"Because trying to see the internal structure clearly will consume too much energy, and if the energy can't keep up, it will definitely faint for self-protection."

This kind of thing has happened too many times, and Ye Hui feels very calm when he talks about it.

Xu Chunhai swallowed his saliva, always feeling a little unacceptable, but these things that happened to Ye Hui that others couldn't figure out seemed to be explained only with her special ability.

"Let's not mention this, didn't I ask you in the workshop today, if I can give you the drawings, can you make the machine tool? The problem is what? ”

also has the memory of two lives, Xu Chunhai's ability to accept is not weak, and he sorted out the language and told the things that happened in his previous life.

Ye Hui listened while eating, and occasionally asked a few questions.

"So it's because we're short of things, right?"

It's like a food chain, they lack something lower.

Xu Chunhai sighed helplessly, the development of the Xia Kingdom in his previous life had been unbalanced, and there had been a lack of refined production.

Everyone knows that this will not work, but compared with these countries, it is steadily backward.

Spending a lot of money can only buy the technology that has been eliminated by others for several generations, which makes them researchers nauseous and helpless.

"Yes, everything is assembled from parts, and what we lack now is these, but parts need equipment to produce, and you can't assemble related equipment without parts, so it's like an endless loop."

Xu Chunhai felt very worn, and Ye Hui rubbed his chin thoughtfully.

"You really can't buy this kind of machine?"

"It's hard, anyway, the one I used in my dream research is not much better than the current one."

That's really a bit bad, Ye Hui can understand Ji Fan and Xu Chunhai's boredom, if it's really like Xu Chunhai said, then it doesn't seem to make much sense for her to draw the drawings of the machine tool.

"Can't we really produce that kind of precision machine tool ourselves?"

"I don't know, I've heard before that after our delegation made many requests, some Western countries were forced to let the members of the delegation look at it from a distance.

"But this glance is not in vain, after coming back, it is indeed produced, but it is not as easy to use as others, and it is easy to break.

"But that's enough to surprise us, it's better than nothing."

Ye Hui nodded, but this is also the case, so it seems that this matter is not without room for maneuver.

They had stolen the latest steel-making technology from Dongguo, and Ji Fan had told her that the pistols produced from the newly smelted steel would no longer jam the bullet case as easily as before.

So in this comparison, they still have changes.

"What year did you refer to that mission?"

"In another five or six years? I don't know exactly what I know, but I was almost thirty years old when I entered the institute in my dream. ”

When Xu Chunhai talked about this, he felt that he couldn't use all his strength, and he was so upset.

"Sister, can you help me figure out a way? I want to enter the research institute earlier, and if I go in early, we will be many years ahead of the submarine manufacturing technology. ”

Moreover, some theories are common, and perhaps he handed over the technology researched by later generations and could also be used in other military manufacturing fields.

With a little eagerness in his eyes, Ye Hui put down the dishes and chopsticks, and she was rarely a little serious when she was full of food and drink.

"I'll find a time to meet the chief, and I'll help you fight for it then."

If Gao Wanguo believes that it is the best reason, if he is unwilling, then he will let Ji Fan find a way.

With her words, Xu Chunhai felt that he had not waited in vain this night.

"Big sister, thank you."

Ye Hui raised his hand and knocked on his forehead: "What are you doing with me so politely." ”

Sending Xu Chunhai away, she heard a slight cry from the house, and quickly ran back to the room to see that Xixi had woken up, as if she was crying because she couldn't see anyone.

Ye Hui picked her up and patted her on the back carefully.

When a child wakes up, it is always easy to solve the problem of three emergencies first, and after changing her clean diaper, she is ready to breastfeed.
