Something you want. Su Dye went into the workshop and put a box on the table in front of Yao Xinyue, after getting acquainted with Yao Xinyue during this time, she was already familiar with Yao's house, and she came in and out freely, and she didn't feel any embarrassment at all, and everyone in the Yao family was no longer as restrained about her as she was at the beginning.

"Thank you."

Yao Xinyue put down what she was doing and opened the box, the last time she heard Boss Zhao say that Qianjiao Pavilion also had a new balm, she has been remembering this matter, I heard that it is difficult to buy, and Boss Zhao can't help it, and then Su Ran came to her house to play, Yao Xinyue thought of her identity, so she casually mentioned it, and Su Ran immediately agreed to help her buy it.

"If you want me to say what are you looking for them to do, I used to think that Qianjiaoge's things were easy to use, but since I used the ones you gave me." Su Ran shook his head: "Compared to yours, they are still far behind." ”

Yao Xinyue was silent, of course it was far away, hundreds of years away.

I saw her open the balm and spread it on her hands.

"How? Is it the same as what you do? Su Ran asked curiously.

Yao Xinyue shook her head, "It's different. Of course it's different, a mechanization, a pure handwork, of course it's different, but she has to admire Qianjiaoge, it is not easy to make such a result in such an era, if she doesn't have a hanging, she can't compare to others.

At this time, Yao Xinyue didn't know that if it weren't for her cream, Qianjiao Pavilion would not have been able to make such a good balm.

——

In the middle of July, the weather was as hot as roasting in a fire, and the trees in the yard kept screaming, making people's heads hurt.

The current workshop is a house built by Uncle Yao's family, and there is only one window, even if the window is opened to breathe, the effect is minimal.

Fortunately, Yao Xinyue installed a fan in the workshop.

The temperature in Yao Hai's noodle restaurant was too high before, and Yao Xinyue had been thinking about how to solve this problem, and then wondered if she could make a fan.

Now there is no electricity, let alone a motor, and she can't get these things as a liberal arts student, but fortunately, there is no electricity, so she will use external forces.

So Yao Xinyue wondered if she could use the wind outside the house to drive the fan to rotate to make the fan in the house rotate.

With this idea in mind, she drew a lot of strange drawings and searched all the craftsmen up and down Peicheng, and finally someone agreed to try it with her.

During that time, Yao Xinyue not only had to work in the workshop, but also had to go to the craftsman to study the fan with him when he had nothing to do.

Because they have to divide the fan into the inside and outside, to make the natural wind blow the fan blades on the roof, and then drive the axle wheel to make the fan hanging in the house rotate, this process seems simple, but it is really very troublesome to do, because to ensure that the shafts on both sides have to rotate, and there will be no failure when the wind is strong.

Not only that, but also to ensure that the fan can be retracted and released freely, that is, you need to make a mechanism on the axle, open the mechanism when you need to use it in summer, and the fan in the house can rotate, and in winter, when you don't need a fan, turn the mechanism off, and only the fan blades on the roof will rotate with the wind.

For this, Yao Xinyue and this craftsman named Geng Ming also deliberately found places with different wind powers to do experiments, and only then tried to install them in the house and use them until they were foolproof.

The first thing to install was Yao Hai's noodle restaurant, and if you want to install this fan, you have to tear down a hole in the roof, and the noodle restaurant was closed for a day because of this incident.

When the mechanism of the rotating shaft was opened, the fan blades on the roof were blown by the wind, and the fan in the house also moved.
