Tianyu said, then looked up at Lin Yu, and said embarrassedly: "Hehe, I'm ridiculous like this, right?" But when I was a child, I liked to study this—"

Unexpectedly, Lin Yu didn't feel bored or didn't understand, on the contrary, Lin Yu's eyes were burning and he said in surprise: "Tianyu, this is not ridiculous, what you said is completely possible!" You see, if the shoe repair machine can be made, then the same should be the same as the machine that makes clothes! Then, there is a spinning machine, there is a weaving machine, and in the same way, a felt weaving machine should also be able to make it! As long as you dare to think and try, many things can be replaced by machines! ”

"So, the Celestial Wolf said you were going to come back and study the machinery with me, is that true?" Tianyu couldn't believe it, he thought it was an excuse for Lin Yu to escape from the sad place, but he didn't expect Lin Yu to think the same as him! It is true that he had used to discuss machinery with Lin Yu, but through a period of observation of Lin Yu, he found that Lin Yu's hobby was more cooking. Pen? Interesting? Pavilion wWw. ｂiquge。 So he once suspected that this machine was not researched by Lin Yu at all, where did she see it, or if it was simply researched by the Li family. But he studied with Li Youfeng for a long time, and finally found that Li Youfeng was talented, but theoretically inferior to him. Unexpectedly, Lin Yu really knew about mechanical things, and he really came to study with him!

"Of course it's true! Otherwise, what will I do when I come back! Lin Yu smiled, and then took out a simple sketch of a sewing machine.

The sewing machine is too complicated, and it is not like a shoe repair machine, and I have watched my grandfather fiddle with it since I was a child. Of course, she has also seen the inside of the sewing machine, but after many years, she can only draw a rough idea, and the details inside need to be studied slowly with Tianyu.

The sewing machine was a great big thing when Lin Yu was a child in modern times, and her parents' generation would be very great if they had a sewing machine as a dowry when they got married. Back then, Lin Yu's mother married into the city, and grandma and grandfather were ruthless, so they married their daughter with such a machine.

Grandpa can repair shoes and make shoes, grandma actually has a good sewing skills, she has always liked sewing machines, she didn't use them, so she gave her daughter a marry.

But later, the conditions gradually improved, and Lin Yu's grandmother still bought one from someone else's house.

In my impression, Lin Yu's own home is always covered with a large square scarf, and his mother rarely uses it to make clothes. But grandma is different, until Lin Yu is in junior high school, the machine is always polished, the oil is very sufficient, grandma is stepping on the lower pedal, while using her hand to pluck the upper wheel, "collapse, collapse" sound, as if tireless.

When she was a child, her grandmother would make her cotton jackets and cotton pants, but when she grew up, she disliked those things as bloated and ugly, and refused to wear them anymore. Now that I think about it, I really miss those days.

Tianyu looked at the sketch Lin Yu gave her, "Miss Lin has ever seen such a machine?" ”

Lin Yu smiled lightly, "Probably I was a little stunned, I saw someone making clothes out of this in a dream, beautiful and finely stitched." Originally, I wanted to start with a shoe repair machine, but I didn't expect to dream about this. When I woke up, I was afraid that I would forget, so I drew this one. ”

There was a moment of disappointment in Tianyu's eyes, but they immediately lit up again.

"It's meant to be, isn't it? However, what Miss Lin said also makes sense, this is indeed a dream, such as the shape on it, I think this piece should be quite complicated, but it can't be reflected in the painting. ”

Lin Yu nodded, she really didn't know much about the internal structure of the sewing machine, she could generally know the principle, and the rest mainly depended on Tianyu, after all, she didn't learn this professionally.

"It's really complicated, there's a hinge, there's a gear, but it's all about the needle on the left, and I think it's a similar thing to a shoe repair machine." And the more advanced place than the shoe repair machine is that you don't use your hand to crank it, but to step on it. ”

"Then how can you turn it when you step on it?" Amane asked. Stepping on your feet does free your hands, but how can you let your feet replace your hands?

"I guess that's the inner crux of the machine above. There is a belt between the pedal and the machine. The belt should be astringent, and it can drag the gears inside the machine above to make the needle rise and fall quickly. Lin Yu explained.

"That's a good way!" Tianyu said excitedly, "This thing is not small, we can't make it in a day or two." So I think let's take our time and study little by little. First figure out the principle, then try to draw a sketch, and then let the people in the arsenal do it. Try a few more times, I think, always succeed! ”

Lin Yu also nodded heavily.

The advantage of having an arsenal is that it is much easier to make ironware. And if it doesn't meet the specifications, it can be re-forged, which is really convenient.

Lin Yu had spiritual sustenance and interest, so he studied with Tianyu even more unsleepably.

In the blink of an eye, it has been ten days since Lin Yu came back, and his contact with Jing Hao is almost his uninterrupted, once every other day. For the rest of the time, except for eating, Lin Yu studied with Tianyu. The two people have studied two detailed drawings of the interior of the machine, but there are still many dissatisfactions. Although it seems boring to outsiders, both of them find it quite interesting.

"Girl, King Xin is here." Dark clouds come in. She just didn't understand Lin Yu's hobbies. Lin Yu used to like to study food, and she could understand it, but now, the dark clouds couldn't help but wrinkle their noses. She was bored every day now, and she didn't know what to do except chat with other slave girls. Even Lin Yu gave her the privilege that she could go back to her house every night, as long as she came to serve by Lin Yu's side during the day. She and Mu Yi are two people, working two shifts.

Lin Yu put down the charcoal strip in his hand, cleaned his hands with the basin of water handed over by the slave girl, and then went out with the dark clouds. For the sake of convenience and accuracy, she and Nobuhito now switch to charcoal strips.

As soon as Tianyu lived in and came out, he saw Nobuhito wearing a silver-white cloak, standing there elegantly, smiling gently.

"Can I disturb you?" Nobuhito smiled and said, "I heard that you've been researching machinery these days, but I didn't dare to come and disturb you. ”

"Why are you disturbing here? Let's talk, I can also be regarded as a combination of work and rest. Lin Yu made a gesture of invitation and welcomed Xinren in. (To be continued.) )
