The whole family of villains criticized her wildly, but the princess treated her with medical treatm

"When my servant girl was a child, her parents sold her to the Mu family and became a servant because her family was so poor that she couldn't afford to eat."

Yuanyang has been freed from slavery. Although her rank is not high, she is still a female official in the eldest princess's palace.

But every time she thought about the difficult life in her childhood, she still couldn't help but sigh, "This is the fate of children from poor peasant families. It cannot be said that their parents are cruel. They are sold into rich families as maids and servants. At least they can beg for food from their masters, and they will not be in trouble." starve."

By becoming a maid, she would have something to eat, and her family would not starve to death with the money from her selling her body.

If you do well in your master's house and serve young ladies, young masters, etc., even if you become a slave, your future will be bright.The prerequisite is that you have smart hands and feet and a smart mind, otherwise you will be beaten to death.

And there’s an old saying.

I would rather marry a servant girl than a girl from a small household.

Work as a maid in a wealthy family. When you are old enough and save enough money to retire and return to your hometown, you can marry into a good farmer's family.Your husband's family also thinks highly of you, thinking that you are capable, good at managing the household, knowledgeable, and have connections in the city.

"Did Zhujiacun have a good harvest this year?"

"A great harvest, half planted with beans and half planted with corn."

Yuanyang smiled from ear to ear, "Thanks to you, I was rewarded with some [-] catties of potatoes and [-] catties of sweet potatoes. I planted more than ten acres of land at home and harvested a lot of divine food! My second brother said that I have a wife. Come on, my third brother and my fourth sister have also entered the Imperial City Academy to study and learn how to read."

Today's good life is something she never dared to imagine.

This is all because of the master's glory.

Mu Tingxue's eyes still fell on the rice and bean beds in the threshing field, and she asked, "Has the village always used this primitive method to thresh the crops after harvesting them?"

"Primitive? Not only our Zhujia Village, but all the villagers in Yundu are like this."

Yuanyang took it as a matter of course, "We beat the rice on the rice bed. If the rice bed is full, we can also do it in the field or on the field. Or if the conditions at home are better, there is a wooden roller, and the rice and beans can be dried in the sun. After that, put it into a wooden roller and let the cattle pull it and crush it repeatedly to remove the outer shell of the crop seeds."

Mu Tingxue nodded, already having a general understanding of the threshing and cleaning situation in Yundu Agriculture.

"After threshing, the chaff, dust, and grass clippings are mixed. Do we need to use the winnowing method outside?"

"Your Highness is smart!"

Yuanyang had a sweet mouth and spared no effort in praising her master. She was a peasant girl. Seeing her master's interest, she explained enthusiastically, "Poor farmers cook and eat the shriveled grains in grains together with the rice. This saves money." Grain. But if it is to be sold for money, it is another matter. You need to use a dustpan to lift it up and let the wind blow away the chaff and chaff inside, leaving behind strong and plump grains; or use a wood mill to lift it up. Throw the threshed rice high into the air to get brown rice."

Mu Tingxue went to Yangchang to take a look in person.

I am extremely sure that in this era, there is no windmill!

Also called a fan truck.

It is a wooden machine specially used to clean grains. It is very easy to use. Even in modern rural areas, you can still see grain windmills.

When she was a child in a village, her neighbor's grandmother's house had a grain windmill. The harvested grain grains were poured into the funnel-like entrance, and the handle was shaken, and the plump and strong grains would come out of the grain outlet. It operated by the power of the wind, and the machine lowered its head. There is a pile of grain husks, chaff and other debris.

This method of mechanical threshing using a windmill is highly efficient and labor-saving.

"Bring a pen and paper."

"Yes."

Yuanyang couldn't guess his master's intention, but he immediately followed the instructions.

Mu Tingxue sat down and began to draw the drawing of Gufengchao - a closed fan car.

The right side is equipped with a wheel shaft, a fan blade plate, and a crank handle. It is a fan that can generate centrifugal wind. The left side is a funnel, which can add grains to be cleaned. The grains pass through the track under the funnel and slowly leak down...

Originally, she planned to come to Zhujia Village to encourage the villagers to plant some tomatoes so that the tomato paste factory could get materials nearby and give Zhujia Village a way to get rich. However, when she saw the rice field being threshed, she built a windmill.

The drawing is done.

Logically speaking, the task of restoring the windmill in the Mechanical Valley must be left to the Minister of Industry, Qin Houye.

Brother-in-law Qin is as busy as a spinning top.

He had just organized his people to restore the sugar cart and stone mill invented by the eldest princess. He produced thousands of sugar carts and sold them to the Tang family. Before he could take a breath, the eldest princess's new drawings came again!

The employees of the Ministry of Works, who were all veterans from aristocratic families, were trying to make money from large-scale construction projects, but now they have been domesticated and become the eighth-level craftsmen of the Yunhuang Empire!

The workload is getting bigger and bigger, and in most cases you still need to do it yourself.

What?You have no skills?A bastard?

Sorry, get out of your position and make way for skilled and talented professionals, otherwise the department will not be able to perfectly restore the eldest princess's drawing machine!

If the targets are not met, Qin Shangshu will be furious and punish them severely.

Mu Tingxue herself didn't even realize that the advanced mechanical drawings one after another had subtly rectified the work department from top to bottom, and the integrity and technical efficiency had been greatly improved.And these truly capable technical employees of the Ministry of Industry all admired the powerful mechanical drawings designed by the eldest princess and were extremely loyal to her.

"This is a grain windmill. It has a wooden structure and does not require stones or iron gears. It is much simpler than the last sugar cart. I have you, brother-in-law."

"Your Highness, this grain windmill has uncanny craftsmanship and is much more practical than the sugar cart!"

The Marquis of Qin is indeed a well-informed man. An ancient mechanical master, after studying for a while, he roughly understood the principle of wind-driven grain cleaning.

Mu Tingxue said: "This is designed based on the different weights of grains and impurities such as chaff and chaff. When the fan handle is cranked by hand, the wind will blow the grains and impurities to different places for collection."

"Even in a good year, the number of good rice will be nine grains and one grain, and unfilled grains will account for one tenth; in a bad year, it will be six grains and four grains. This kind of grain windmill of yours can easily screen and remove the rice grains. than."

The Marquis of Qin was full of praise.

He couldn't wait and started working.

The Ministry of Industry also came with two assistants, and it only took one day to build the pure wooden windmill.

By evening, a brand new windmill was ready.The total length is 1.5 meters, the width is five to six meters, and the diameter of the fan is about one meter.

“In the future, wherever there is farming, there will be windmills.”

Mu Tingxue personally demonstrated the operation.

As the operator, the hand cranks the handle to drive the centrifugal blower to generate wind, and the grains filled with impurities to be cleaned are poured in from the hopper. In an instant, good quality rice is collected at the grain outlet, and the end of the air duct is Blown debris.
