In front of the main hall of the second courtyard, Zhu Yuan had just gotten off the sedan chair, and Jin Dahu and Wei also stepped forward to salute together.

Signaling the two to get up, Zhu Yuan came to the house and sat down, Shang Li took the other two chamberlains to bring tea, Zhu Yuan had already asked Wei Ye: "Is the mattress ready?" ”

Wei also subconsciously wanted to get up, and when he saw Zhu Yuan pressing his hand, he sat down again, straightened up and said respectfully: "It's done, but I don't know if it's in line with the hearts of adults, if it's not appropriate, the lower officials can change it at any time." ”

Shang Li, who came forward with a cup of tea, bowed down and carefully interjected: "The writer is already asking people to move it to the inner house, and according to the instructions of the adults, put it in the innermost courtyard." ”

In the middle of the mansion on the lake is a five-story courtyard, Zhu Yuan's daily residence is the fourth, and there is a heavy one behind, which should have belonged to the main room of the mansion, which has been empty before. Zhu Yuan didn't think about marrying, so he casually made a fuss.

Waiting for Zhu Yuan to take a sip of tea, Jin Dahu followed and spoke: "My lord, the lower official brought the small scale you ordered, as well as some ideas for the 'gossamer escapement' used for pocket watch making, and Brother Wei also brought a few sets of spring samples, do you want to take a look?" ”

"Of course we have to see."

Shang Li quickly picked up the things.

Zhu Yuan first looked at a stack of manuscript paper, on which were drawn pages of fine and beautiful mechanical structure drawings, and, as expected, among Jin Dahu's drawings, there were also many drawing standards from his side, such as the most common one, digital annotation.

Just glanced at it, and didn't distinguish the content, Zhu Yuan couldn't help but praise: "Dahu, your painting is good, you can be a gentleman." ”

Jin Dahu owes a debt: "My lord's praise." ”

"It's not a false praise, to be honest," Zhu Yuan said: "I have thought about it again in the past two days, Wei Ye, you will study at Jinling University first, and when the University of Technology is established, you can become a doctor of the 'chemistry major' over there and bring out a class of students." And you, Dahu, with a belt of 'mechanical professional' is more than enough. Although the University of Technology will also accept other students, it is mainly for you craftsmen, and the two of you will enter as pioneers, and you will be ancestor-level figures in the future. ”

Zhu Yuan mentioned Wei Ye's matter two days ago, and Lao Zhu knew a little about it, and readily approved Wei Ye to study chemistry at Jinling University. After that, Zhu Yuan also thought more, whether it is the industrial university that is being promoted or the other two Jinling University and the national university, teachers are the biggest problem, so that many emerging majors can only be self-taught and self-researched. Now, such as Jin Dahu and Wei Ye, they are simply ready-made, and they don't need to be used in vain.

It's only been a few days, listening to Zhu Yuan talk about the University of Technology and their thoughts on them, the two of them are excited and hesitant.

The significance of the University of Technology is easy to imagine for the two people who were born as craftsmen and have sufficient knowledge and understanding. Moreover, the 'doctor' mentioned by Zhu Yuan is a positive seventh product.

In a short period of time, from the ninth grade to the seventh grade, they had not thought about it before.

However, another problem is that going to a technical university to be a gentleman, even if it is a 'doctor' of Zhengqipin, is ...... It seems to have some influence on the future.

Zhu Yuan leaned on the big chair covered with thick mattresses, flipped through a page of drafts, looked up by chance, noticed the expectant and tangled expressions of the two, and said with a smile: "I didn't let you be a gentleman all the time, and the affairs of the two workshops can't be put down, mainly to bring out a group of students in a few years, and although you have an official position, in essence, you are still students, learn more things, and you can go further in the future." ”

When Zhu Yuan said this, the two glanced at each other, did not hesitate any longer, and at the same time got up and bowed to Zhu Yuan: "Master Xie to carry you." ”

"Get up."

Zhu Yuan waved his hand, turned back to the artwork in front of him, and didn't speak again for a while, admiring it seriously.

A few days ago, he went to the watch engraving workshop and put forward the idea of making pocket watches, Zhu Yuan only remembered the term 'gossamer escapement' that had no specific concept at all, but he didn't expect that in just a few days, Jin Dahu came up with several sets of plans.

The core is made of spring filaments of different shapes to realize the reciprocating motion of the escapement, which can only be achieved by the previous pendulum.

After reading it, Zhu Yuan turned to the samples of the three 'gossamer escapements' escorted by Jin Da, all of which were very small, but not small enough to be stuffed into a pocket watch, and the smallest one was the size of a palm.

Seeing Zhu Yuan pick it up, Jin Dahu explained beside him: "My lord, the size can still be compressed, this is to make it easier for adults to appreciate." ”

"Not bad."

Zhu Yuan said, skillfully finding the mechanism and turning the winding, and the escapement system in front of him immediately 'clicked' to work.

I tried the other two and it was the same.

After fiddling with the three samples, Zhu Yuan put down the escapement system with a ring spring filament in his hand and said: "Do you know what the key to the hairspring escapement is?" ”

Jin Dahu nodded: "Without that pendulum, there will be no 'isochronism' that adults say, what the lower officials have to study is how to make this 'gossamer escapement' have a similar effect to 'isochronism', so that the pocket watch can be made accurately." ”

"That's right," Zhu Yuan said, "but how to do it, you have to rub it yourself, just like the 'isochronism' of the pendulum, I believe that as long as you are willing to study, you can also discover other 'isochronism' phenomena." ”

Jin Dahu assured: "Xiaguan will do his best." ”

After saying this, Zhu Yuan turned to the two small scales.

The first miniature version, which resembles the one with a large scale that has been reduced by dozens of times, looks like a delicate model, with the weighing table at the bottom and connected to the rod and scale above by a lever structure.

The second is the kind of balance scale in the laboratory that Zhu Yuan once remembered, with items on one side, weights on one side, and graduated weights in the middle.

Jin Dahu also introduced on the side, the two nicknames, are made with reference to the standard of the child, the minimum can be weighed to 1 cent, that is, 1 percent of the money, the maximum can be weighed 1 tael.

Zhu Yuan asked Shang Li to find a few copper coins and weigh them with great interest.

Very precise.

Jin Dahu took the initiative to raise the problem: the mini scale connected by the adapter lever is not very accurate because of the complex structure, especially after a long period of use. Other balance scales, because of their relatively simple structure, are also more accurate.

Zhu Yuan felt that it made sense.

So he quickly made a decision, and later asked people to send the balance scale to the palace to Lao Zhu, with some ideas of his own. After that, let the Ministry of Industry make a batch for teaching, or distribute it to various departments of the imperial court.

The main advantage of the balance scale is that it is easier to operate than the scale, and in the future, various majors of various universities, especially the kind that needs to carry out a lot of experiments, will have a lot of weighing needs.

Not only that, but if you do more, you can also sell it.

It just so happens that the imperial court wants to issue sterling silver coins, and the demand for weighing in all walks of life will increase significantly in the future, after all, it doesn't matter how many centimeters more copper coins are, silver coins ...... The size of a soybean is equivalent to 100 yuan later, and even 1 percent is 1 yuan after deducting it, which is not good.

Only then did he turn to the spring sample sent by Wei Ye.

said casually that day, and then passed on several times to discuss, Zhu Yuan finally determined that the thickness of the mattress was half a foot, about 15 centimeters, of which the height of the spring was 4 inches, with several layers of strong skin.

There are only springs in front of you.

Among them, the steel wire of spring steel has thickness and thinness, and the diameter of the spring made is also different in thickness, which is also discussed before, Wei also feels that the spring in different parts of the mattress should be different in size and thickness, so as to ensure that it is not deformed as much as possible.

Zhu Yuan has no opinion.

At that moment, he pulled and fiddled for a while, and noticed that the steel wire breaks at both ends of the spring were carefully wound with a fine cloth to prevent cuts, and Zhu Yuan suddenly remembered it again.

Once a mattress or a spring in a sofa...... It seems to be ...... It should be made into a spring bag.

That is, each spring is wrapped in cloth.

Zhu Yuan doesn't know the reason, but since it is generally done in the industry, it obviously makes sense.

Although I thought about it, I didn't mention it.

Perhaps one of the benefits of the spring bag is to prevent the spring wire from jumping out and piercing people, but Zhu Yuan believes that Wei Ye and they will not make such a mistake in detail, just like several springs at this time are finely wound at both ends.

Then it doesn't matter.

After all, the fabric was still very valuable in this era, and it could be used as currency, and it was also an expense to hold every spring.

More on that later.

After reading things and saying some words, Zhu Yuan served tea and sent it to the guests.

Sending Jin Dahu and Wei Ye away, Zhu Yuan immediately came to the backyard of the inner house.

Big mattress!

Entering the main house here, the mattress has been moved in and arranged in the master bedroom on the east side.

Zhu Yuan walked in, freehand was taking a group of maids to clean up, and the blank space that didn't show up much these days was also there, but he was standing next to him, looking at the big mattress, his face was full of disgust, and he almost said that this was too serious.

Truly.

Seeing it with his own eyes at the moment, Zhu Yuan reacted to how big the one zhang long and one zhang wide he casually ordered before.

Anyway.

It's so big......

The bed frame was erected on all sides, and the curtain was erected, and when I looked at it, it was not like a bed, but more like a ...... A room.

After taking a look, Zhu Yuan casually grabbed the blank space that was about to leave after giving a salute: "Go up and jump, this is a spring bed, it's very comfortable." ”

Liubai was pulled by his own adult, and he had no choice but to stop, but he said, "My lord...... Let Sister Freehand go up, the slave can't stand it. ”

As he spoke, he was going to leave again.

Zhu Yuan continued to hold on, and Nizi didn't dare to use force, but resolutely refused to step forward.

Zhu Yuan pretended to be angry: "I just told Xiaoyu, you are the most disobedient by my side." ”

Blank was immediately vigilant: "That Nizi...... Chew your tongue and see if the slave doesn't tear her mouth. ”

Zhu Yuan: "......"

Chewed?

It seems that there is.

It seems like...... Nor did it.

Does not talking count?

So he laughed: "If you want to tear the mouth of the little fish, you're afraid you won't be able to beat it, my sack is a water lady." ”

I remember that when I was still in Mingzhou, Zhu Yuan was assassinated, and a certain Nizi dragged a person out of the water one by one, so it became a strange story in Dinghai County.

Now I don't know if there are any country people who have built temples.

Liubai is obviously not afraid: "The water lady will not be majestic when she comes out of the water, and the slave will tear her mouth later." ”

Nizi said and struggled lightly, Zhu Yuan no longer insisted, let her go, and pleaded for the sack with a smile: "Light, be careful that she really beats you if she is in a hurry." Also, I haven't seen you in the past few days, come, my father......"

Zhu Yuan turned his face sideways as he spoke.

I was reluctant to leave blank, but seeing the expressions of a few Nizi around me, I wouldn't let it, so I still leaned over and pecked Zhu Yuan on the cheek.

Then he hurried away with a red face.

After the blank ran away, Zhu Yuan stepped forward, and Cai Sang and Hai Er immediately opened the curtain a little.

Zhu Yuan didn't bother to open the sheets to see what the mat looked like, so he sat on it directly, and it was upside down, soft and elastic, and he felt ...... Very right.

The sofa can also start to be done!

So he stretched out his hand to Freehand: "Come, let's take a nap together here today." ”

Freehand also shook his head: "There are a lot of things," he said and motioned to the maid on the side: "Let them accompany them, just right...... It's so big. ”

In the end, there is still a little yin and yang in the tone.

It's so inconsequential.

Zhu Yuan lay down, rolled, felt more right, raised his feet, Qingping and Dianjiang next to him smiled and stepped forward to help their adults take off their shoes, Zhu Yuan rolled all the way to the innermost, and rolled back.

Back and forth.

Standing next to him freehand, looking at his own adults, who are always too mature in their daily lives, rarely show their childish side, they don't mind anymore, and take the initiative to signal to Cai Sang a few times, let them go up too.

The six girls actually wanted to do it, but they couldn't understand the mood of the freehand sister at this time, and they seemed to be twisted. However, the mentality of competing for favor is greater than the scruples about freehand, and it still climbed up quickly.

And then they were disgusted.

"A group of small ribbon fish, go down."

So I had to go down.

Also aggrieved.

Why do other masters like their tender little daughters, their own ...... How could it be different?

Driving a group of little chicks down, Zhu Yuan continued to roll, but his mouth read: "Yan Shan, no evidence, blowing the horn, looking at the break, wandering, exhausted, jagged, shaking ......"

Listening to it freehand, of course she understands, she actually thinks that the preferences of her own adults are not normal.

But it's also helpless.

When Zhu Yuan read more than ten or more than ten and couldn't think of it again, he said softly with a bit of pampering: "Got it, Dad...... The slave went and called them over. ”

"Uh-huh."

Actually, Zhu Yuan didn't have any other ideas.

I just want to try it, how many can you lie on side by side on this big bed.

After all...... I'm a data controller. Data control likes to measure and collect all kinds of data at any time, which is normal!

Freehand said, but did not leave immediately, and when his own adults were tired of rolling, he went up in person, first helped his adults take off their thick coats, and covered them with quilts, leaving Cai Sang and Hai Er two girls to take care of them, and then they left.

Today is the twentieth month of the lunar month, the New Year has arrived, as the housekeeper of the huge Pingzhang house, there are indeed too many things in the daily life.

However, he still came to the front first, and after explaining that a group of women went to the back to accompany his adults for a lunch break, he turned to his own affairs.

When a group of women with different charms came to the backyard after being full of elaborate dressing, they found that their own adults had fallen asleep after a hard morning.

In the strange bed of the room, the little boy slept quietly, and in the eyes of several of the women who were inevitably sentimental after the change in Noh poetry and painting, this picture ...... It's lonely.

Lively and lonely.
