Li Yue'er's work efficiency was very fast, and she had enough people the next morning. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoMost of the people are still from Sunjiaji and Shoushan Village, and there are also people from other villages. There are too many people, and the space is a little insufficient, and some workers have to work in the yard.

The workshop is working in full swing, and at the same time busy building a new house, so it is not lively. Zhang Yun instructed the stewards to manage it well before going home.

Funding is now a big problem, and Zhang Yun can only make another one-shot deal.

She returned home and spent a whole day drawing the structure of the mechanical scale from memory. Mechanical scales work using the unequal arm lever principle. It is composed of a load-bearing device, a reading device, a base lever and a scale body.

When Lu Yun saw it, he was even more impressed by Zhang Yun, he couldn't imagine that there was such a genius in such a small place. This kind of tool obviously has a great use, but I don't know where Zhang Yun learned such a powerful design. Zhang Yun didn't say it, he naturally wouldn't ask, just praised it again and again!

Early the next morning, Zhang Yun went to the town with the drawings. She went to Ruyi Pavilion first, which is interesting, Zhang Yun has cooperated with the Wang family a few times, but she has never been to the Wang family, and she doesn't even know which way the door of the Wang family opens.

When the shopkeeper heard that Zhang Yun was looking for a young master, he hurriedly instructed his right-hand man to send Zhang Yun to the palace. The Wang family's house is on the side close to the county seat, and from a distance, the house is huge, and Zhang Yun can't see how many times it has entered. When they arrived at a corner gate in the east, Zhang Yun got out of the car with his buddies and walked into the yard. A porter had already come over and led Zhang Yunde's donkey cart to the side.

The corner gate is lined with green trees and planted with various plants, and now the chrysanthemums are blooming. The places where there are no planting things under your feet are all paved with green bricks. The pavilions in the courtyard are extremely elegant. Zhang Yun followed the man through a few corridors, and then passed through two courtyards, before he heard the man say, "The courtyard of the second young master has arrived." ”

The children of the Wang family are sorted by age: the eldest young master Wang Ziteng (bachelor of Hanlin, now 24 years old) and the third young master Wang Zixing (Juren, now 15 years old) are the sons of the eldest master Wang Wei, and the second young master Wang Ziming (the manager of the Wang family's estate, 23 years old) and the fourth young master Wang Ziyang (13 years old) are the sons of the second master Wang Zhi. The rest have many sisters.

Zhang Yun looked up and saw three big words "Listening to Songyuan" hanging on the courtyard gate. The guy shouted, and a teenage girl with a round face came and opened the door.

The guy smiled: "Girl, this is a guest in the house, I have something to do with the second young master, and I am tired and accommodating." ”

The little girl answered, turned and walked away, and in a moment brought over a tall girl of fifteen or sixteen. The guy hurriedly said: "Copper girl, this is Miss Zhang Yun, the young master knows." Then he added, "It's a business thing." ”

The copper girl listened and led Zhang Yun inside. The man retreated and went back to Ruyi Pavilion to resume his life.

When I got to the courtyard, there were no pine trees in it, and it seemed that the name of the courtyard was just a vassal elegance. This courtyard is different from other places in the Wang family, and it is extremely luxurious inside. It is now mid-autumn, but all kinds of flowers are blooming in the yard, and they are happy and glorious. There is a plaque hanging on the main entrance, which reads "Full of gold and jade". Zhang Yun not only smiled, this second young master is really a wonderful person.

The bronze girl smiled: "I've heard of you, it's so small." Cream cakes are often eaten in the house now, and that's your credit. Our young master still talks about you a lot. ”

Zhang Yun smiled slightly: "Don't dare to be! This secret recipe was bought with money from the house, so naturally you can use it however you want." It has nothing to do with me, and it doesn't have any credit. ”

The copper girl couldn't help but glance at Zhang Yun carefully, nodded slightly, and walked towards the main hall.

She asked Zhang Yun to wait first, and told the little girl to put on tea and go to the backyard by herself. After a while, Wang Ziyang came over. He was followed by a beautiful woman in gorgeous clothes, and the two looked intimate, they should be the second young lady. It is unreasonable for an adult man to see an unmarried girl alone, so the second young lady comes to accompany him.

Wang Ziyang stepped forward and said, "It turned out to be Miss Zhang, what a rare guest!"

Zhang Yun stood up: "Second Young Master Wang is good, young lady is good." ”

The woman with willow eyebrows and almond eyes smiled: "You know me." ”

Zhang Yun said honestly: "I don't recognize it." It's just that besides Madame, who else could be next to the second young master?" "Funny, in the Wang family's house, this woman is very intimate with Wang Ziming, and she is wearing a bright red skirt, who else is there besides his wife?"

But Zhang Yun's statement obviously made the woman very happy, and she smiled: "This little girl is really interesting." ”

Zhang Yun obviously didn't want to say any more meaningless things, she said with a straight face: "Second Young Master, I'm here to talk about business today." ”

Wang Ziming is very interested in Zhang Yun's business, and the previous birthday cakes and jellies are very successful cases. He stepped forward, "Oh, what's the recipe this time?"

Zhang Yun shook his head: "This time it's not food, but a kind of machinery, the name is mechanical scale." It has the potential to change a pattern -- and from it, people's lives can change dramatically. Zhang Yun said, took out the drawings in his arms, and handed them to Wang Ziming.

Wang Ziming took it with a smile, and saw that it was a dozen drawings, so he opened it casually and looked at it. Looking at it, the smile on his face disappeared, and only the shock on his face remained. He turned to his wife and said, "Go find my mother and let her go to the study." Let's just say that there are important things. The second young lady was taken aback, and she didn't understand what would alarm the second lady. Since her husband took charge of the family's property, her mother-in-law has not been involved in these things for a long time.

The second wife, the Qin family, came from the Qin family in the south of the Yangtze River, and the Qin family was a well-known business family in the country, and the wealth was rivaled by the country. Although the official position of the second master is not very high, the Qin family still married high when he married into the Wang family. After all, the Wang family is a scholar family, and the Qin family is a businessman.

But she didn't ask much, nodded, and went out.

"Miss Zhang, let's go to the study to talk. "If Wang Ziming regarded Zhang Yun as a little clever girl in the past, now he regards her as a only genius!

Zhang Yun was very satisfied with his reaction, dealing with smart people is easy to deal with. Seeing that Wang Ziming was so deeply aware of the huge prospects in this, Zhang Yun suddenly changed his mind. Perhaps, this time she can cooperate with the Wang family by buying shares.

When he arrived at the study, Wang Ziming personally poured Zhang Yun a cup of tea. Zhang Yun took a sip, so fragrant green tea~! She is not good at tea ceremony, and can only distinguish the types of tea, such as green tea, black tea, black tea, etc., and the specific varieties are indeed not drinkable except for Xinyang Maojian.

After a while, a dignified middle-aged woman, about forty years old, came in from outside the door. followed by the second young lady and a group of maids.

"Mother, are you here?" Wang Ziming stood up to greet him. Zhang Yun also hurriedly stood up.

The second lady Qin Shi nodded, and she had already looked at Zhang Yun all over. She nodded, waved her hand to the back, and the second young lady led everyone to retreat.

"Mother, you see, this is a scale drawing made by Miss Zhang. If this tool can be done successfully, it will be much more convenient to weigh bulk goods in the future. Wang Ziming handed the drawings to the second lady.

The second lady sat on the Taishi's chair behind the study and looked at the drawings.

"My mother was born in the Qin family in Jiangnan, and the Qin family is the No. 1 business family in Daqi. Wang Ziming himself didn't know why he told Zhang Yun this.

Zhang Yun was really taken aback.

The second lady looked more and more carefully, and said, "If it is really useful, then this kind of scale will definitely have a place for development in the future." Miss Zhang, have you practiced it?

Zhang Yun shook her head, she really has never actually operated it in her life, and she can't find a craftsman to make this kind of complex machinery, otherwise she wouldn't have come to the Wang family, and she would have produced and sold it by herself a long time ago.

Seeing that Zhang Yun was just talking on paper, the second lady laughed: "In this way, whether this thing can be made or not!"

"Definitely. Zhang Yun replied, "Although I haven't done it, I've seen others do it." Truth be told, it takes skilled craftsmen to make such a machine. I can't find such a person for the time being, but I believe that the Wang family can. ”

"The structure and function of the parts are already indicated on the drawings. You see, when the weighed object is placed on the load-bearing plate, there are four components acting on the key knife of the long and short levers, and the force is transmitted to the key knife of the metering lever by the force point knife and the connecting hook of the long lever. By manually adding and subtracting weights and moving the weights, the metering lever is balanced, and the indicative value of the weighed mass can be obtained. Zhang Yun said a technical term, and the second lady and Wang Ziming didn't seem to understand.

"For example, if we move stones, if the stones are too big for manpower to move, we have to pry them with wooden sticks. When prying, a support should be placed under the stick, and then the longer the length of the stick on the side of the support, the less effort we have. This is the principle of leverage, which is what I just called leverage. Zhang Yun said as he drew a simple schematic diagram of the pole.

Wang Ziming nodded again and again: "I know this, it turns out that this method still has a name." I didn't expect a small lever to have such a big effect. ”

The second lady attaches great importance to it, everyone knows this practice, but it is impossible to design it into such an ingenious machine, this Zhang Yun is indeed a genius!

Seeing that they had accepted the mechanical scale, Zhang Yun began to describe its prospects: "As soon as this kind of scale comes out, all industries can use it! Small goods as light as ten catties and bulk items as heavy as thousands of catties can be weighed with scales, and there is no need to worry about weighing goods in the future." This mechanical scale has a simple structure, accurate measurement, as long as there is a flat and solid scale frame or floor can be placed and used, and the scale body is sturdy and durable, with 4 wheels, easy to move. As far as she knows, at this time, even more than 100 catties of things have to be carried by several people and weighed with rods and scales, which is extremely inconvenient.

"I don't know what Miss Zhang Yun plans to do with this business?" the second lady was anxious, but asked with a normal face.

"I hope to work with the Wang family. I will provide technology, and the Wang family will contribute manpower and material resources. I want a 10% bonus. Zhang Yun replied.

Haha, the counterattack of science and engineering, is this a unique technology?
