Song Juren and Fang Qing had thought that Zhang Yuan's workshop was located underground, so it must be a gloomy and dim environment, where groups of ghost-like craftsmen were sweating and working hard, however, when the little peanut who led the way really opened a stone door on the ground in a remote courtyard and took them underground, they felt that after passing through a corridor, they felt that their front was suddenly bright.

I saw that in the spacious stone room, the top and all sides were densely covered with countless air holes and skylights, and a large amount of light was shining in at this time. At first, they thought it was empty, but when Song Juren approached a wall curiously, they realized that it was not transparent, but embedded with crystal!

Knowing how valuable the crystal was, he couldn't help but smack his tongue secretly, but then he heard the emperor say: "When King Lu built this courtyard, he claimed to use crystal to build a temple for his biological mother, Concubine De, and the queen mother thought that these crystals had been accumulated in the palace for a long time, so they were given to him, but he used them here." In this stone chamber alone, tens of thousands of crystals have been used. ”

Fang Qingdeng's brows furrowed, and just as he wanted to comment, he was really poor and luxurious, when one foot was suddenly stepped on heavily. He glared at Song Juren on the side, the emperor himself commented on King Lu, what do I say two words? In a depressed mood, he looked around, and then noticed that not only did he not notice any humid and stuffy atmosphere here, but he could even feel the flow of air.

He couldn't help but tear off the sweat towel around his waist casually, pinched and raised it with two fingers, and when he confirmed that the sweat towel was swinging slightly with the wind, he immediately exclaimed: "There is wind here?" ”

"Of course there is wind, otherwise so many people are doing things here, wouldn't everyone be suffocated?" Little Peanut glanced at Fang Qing obliquely, only feeling that people had no knowledge, "There is a blast furnace behind here that specializes in ironmaking, and it was originally intended to be moved underground, but the young master said that the iron must ensure that there is enough air, and it must not be placed on the ground." He also said that Yang Qi is needed for combustion......"

Little Peanut didn't pay attention to the fact that he turned the oxygen that Zhang Shou said to Guan Qiu into yang energy, and he just said it vigorously, "The young master also said to Guan Qiu that he should use more water power, fortunately, this Zhang Yuan was brought in by the King of Lu in the past, so Brother Guan pushed the blower with water power and poured a lot of fresh air into here, and other machines in this workshop also have water power ......"

Although it is now learned and sold, and there are even many places where it is sold wrongly, Xiao Peanut is not stunned at all when he is showing off in front of the emperor and the two lifters. Although he now lives with Xiao Cheng in Xiao's house most of the time, while increasing his literacy, he memorizes poems, and at the same time goes to listen to Yu Xiaozhu to listen to the drama when he has nothing to do, it does not prevent him from peeking at the textbooks sent by those students in Jiuzhangtang.

He couldn't understand the math that was too esoteric, but he secretly wrote down some of the simple ones. At this time, seeing that the three people in front of him were listening attentively, he couldn't help but be very proud.

But the next moment, he heard a clear voice, and then he saw that the three people who had just been listening to him intently turned their heads almost in unison.

"This foot-pedal grinder needs to be improved...... Hey, after all, the water flow of this garden was introduced, the height difference was not enough, the strength was too small, and the water power that could be used was limited...... Refined iron and brass are not compared to jade, what we have to do is not to carve jade, but to grind parts, it is too laborious to step on, if not improved, a grinding machine to two people to step on, isn't it labor-intensive? ”

"Although the first pendulum clock is done, it is all hand-ground parts, the rejection rate is too high, and it is not accurate, so even if the sample is sent to the palace, it must be improved, although the second one is used in mass production parts, but the accuracy is enough, the scrap rate of the parts is still too high...... Even if you can really sell at a high price, the yield rate is very important! ”

"If only there was natural rubber as Brother Zhang said, in that case, the huge power of boiling water is better than the water and wind power that will not be available from time to time!"

Seeing the oily young man running around by this person and that person, sometimes pointing and sometimes complaining about something, Song Juren and Fang Qing couldn't help but feel suspicious, but then they only heard Xiao Peanut say: "This is the eldest brother Guan that Gongzi admires the most, he said that the emperor praises people as master seeds." He's a man who likes to ask why, he's studious, and he's hands-on......"

He put on a lot of high hats for Guan Qiu in one breath, not caring that the master in his mouth didn't notice them at all, and he was still busy there.

And the four princes, who were carried by Hua Qi and sneaked in from another entrance, had a feeling of being a snitch thief at this time, excited and frightened.

At this time, seeing that the twenty or thirty people not far away were operating on all kinds of strange machines, he couldn't help but stick to Hua Qi's ear and whispered, "Uncle Hua Qi, is this the teacher's workshop?" But why can't I understand what I make? ”

"I don't understand it either." Hua Qi shrugged his shoulders and gave a very cheerful answer.

Hearing that the fourth prince behind him stopped talking, although he couldn't see people's expressions clearly, he also knew that the little guy behind him must be dumbfounded, so he smiled and said: "Your teacher is a very strange person, even the eldest lady is his future wife, he may not really understand him, let alone others?" ”

"The person who can understand him in this workshop is probably that little Guan Qiu, and even if it is him, he can probably only understand part of it. Your teacher's teacher, I don't know which of the great men who have traveled overseas and are truly well-read, is much better than those who claim to be erudite in the DPRK and the people. ”

"That's why Mrs. Ge defends your teacher so much, and even when others question your teacher's inheritance, he blocks them one by one. To be honest, no one expected that it could be done like this according to Taizu's relics. "Even the emperor didn't expect it!

The emperor really didn't expect that in less than a year, Zhang Shou actually dismantled the strange timepiece he took out of Taizu's secret box, and then really imitated something - although one is extremely small, the other is huge, and the shape is completely different, but the most basic thing, that is, the movement of the disc is the same.

When Little Peanut stepped forward to stop Guan Qiu, and when Guan Qiu saw him, although he didn't understand who he was, he just bowed his hand, but he didn't ask anything, as if he didn't pay attention at all, and brought him and the others to the pendulum clock. He knew that this young craftsman was actually a tendon, and his eyes were quickly attracted by the pendulum clock that was the same as the one that Hua Qi secretly sent into the palace before.

Watching the pendulum swing back and forth, and then watching Guan Qiu open the lid on the top and unsuspectingly show him the simple and even shabby structure in it, even if he had seen something more complex and delicate, he still couldn't help but be a little amazed at this time.

At that moment, the emperor asked, "How is this thing compared to the pendulum clock that was sent to the palace before?" Is it more accurate? ”

Guan Qiu replied very briskly: "The accuracy is not as high as the pendulum clock sent to the palace, but the outer shell has a better pattern." His words were unusually simple and clear, not even pretentious.

"The pendulum clock that was brought into the palace was made and ground with a number of the best craftsmen on grinding machines and other machines, all carefully selected. They are all the best blacksmiths and carpenters, but now these parts are inferior, because although they are also made with grinding machines and so on, the machine is not good enough, and the craftsmanship is not enough, so the accuracy of the parts is not consistent, and it needs to be adjusted. ”

"So in the end, the accuracy of these pendulum clocks varies, and some even slow down by a few seconds a day. According to what Brother Zhang taught me, an hour has 7,200 seconds, which is really not accurate enough......"

When he said that the machine was not good enough and the accuracy was not high enough, Guan Qiu's face was full of seriousness, and he was indeed sighing in his heart. And when he said that he would use the machine to make the metal parts needed by the machine itself, and then assemble it, so as to make more machines, Song Juren and Little Peanut were just that, but Fang Qing's eyes lit up.

This young man, who was thought to be reading too much by the head of his own Zhaoming Academy, was so much that he often said the wrong thing to offend people, and at this time he couldn't help but ask: "This machine is also made by machines, isn't it like a hammer and a hammer to beat?" ”

"Well, you can't say that, the hammer is cast, unlike the sword, which still needs to be beaten." Guan Qiu didn't quite understand what Fang Qing's expression meant. In fact, even if he hadn't seen the emperor, he knew that it was a big man who could be brought here, but he was not as timid as ordinary people when they saw a big man, but he seemed very bland.

At this time, he explained solemnly: "In fact, to put it simply, it is like a chicken laying eggs, and eggs laying chickens." The chicken lays eggs, but hatches chickens, and then the chickens regenerate eggs...... Readers often think that it is a difficult question to solve whether there was a chicken or an egg first, but in my opinion, it must have come first. ”

"Because just like these machines, the first part they make, because it's hard to fit the drawings exactly, almost all of them are not like four. Well, the chicken must be the same, it may not be an egg in the first place, but something else, but it can also hatch chickens. Brother Zhang said that living things are constantly evolving, and the chickens raised now are not the same as the pheasants of the past. ”

Such a simple analogy, even Little Peanut was stunned when he heard it, but Fang Qing couldn't help but say: "According to what you say, this is really in line with the cycle of Tai Chi, the way of endless life!" Someone in our Zhaoming Academy once divided a piece of land into the style of a Taiji diagram, and then planted it in two pieces, yin and yang, and it is said that the yield per mu has also increased a lot......"

If Zhang Shouren was here, he would definitely nod with a smile on his face, comment on something casually, and then complain in his heart that you are metaphysics, not science, so don't laugh at the Fang family. However, in Zhang Shou's absence, Guan Qiu's reaction was much more straightforward.

"Using the style of Taijitu to build houses and walls can play a role in defending against bandits and bandits, but in the real troubled times, when there are soldiers and horses everywhere, the top is still the outer layer of dock forts, otherwise it will really be hit by a large number of soldiers and horses, and even if it is a labyrinth, it can't help but catch a fire. What's more, using Taiji diagrams to grow crops will increase yields, which is unrealistic. ”

Without waiting for Fang Qing to refute, Guan Qiu said seriously: "If this son really thinks so, then why don't you draw a piece of land in Zhang Yuan to make the style of the Taiji Diagram, and then grow your own vegetables and try it?" Anyway, there is a lot of spare land at home, and doing experiments on your own is far more useful than listening to people's empty words. ”

Seeing that Fang Qing was stunned at first, and then he really went to the side to ponder, the emperor was simply angry and funny, thinking that this young man who sued the fourth prince and questioned the third prince's cheating was really a nerd with a tendon.

It's just that he was more interested in Guan Qiu's words just now, and immediately "inspected" those machines that were more than twice as many as Hua Qi told him. Listening to Guan Qiu's introduction of how these things were improved again and again, he listened carefully, and when he heard what Guan Qiu said inadvertently, he was shocked.

Brother Zhang said that machines are for people, in order to liberate people's labor, so that more people can read and write, can design more and better machines, and then liberate more people from repetitive labor, and then design more and better machines. And so on, that's the real prosperity. ”

"It was not a good old age to tie people to the land to cultivate. Because only in the era when the productive forces are too backward, a person has to face the loess every day with his back to the sky, and then support himself. ”

Guan Qiu didn't notice the emperor's expression, and when he arrived at a grinding machine that was being dismantled and repaired, he personally leaned over to inspect and discuss, completely forgetting that there was a big man beside him.

When he stood up again, he wiped his dirty hands casually, and then smiled at the emperor. The smile was clear and clean, just like the serious look in his eyes at this time.

"In the past, when I was apprenticed to learn art, Master didn't like me very much, thinking that I liked to ask questions and ask questions, and I didn't learn the craft very well. Brother Zhang not only didn't bother me, but also taught me a lot of things that I didn't expect, and he also told me that if I learn mathematics, physics and chemistry well, I am not afraid to go all over the world. ”

On the side, Hua Qi was carrying the four princes on his back and had already quietly touched it. When he heard Guan Qiu relay Zhang Shou's words, the four princes couldn't help but show an extremely subtle expression. Especially when I saw Guan Qiu holding a booklet and opening it in front of his father, he immediately said generously about what gravity is and what is the periodic formula of motion of single pendulum vibration...... His eyes lit up as he listened.

The four princes who have a certain mathematical foundation are all like this, Song Juren glanced at Fang Qing who was thinking about using the Taiji Diagram to farm the land at this time, and suddenly became a little envious of this guy who had escaped a painful baptism. And the little peanut is what Zhang Shou said about mathematics, physics and chemistry, listening to Guan Qiu's words at this time, it is even more bitter than a bitter gourd.

In contrast, as a student of Ge Yong, he can teach himself the new compilation of Ge's arithmetic, and he can also teach the emperor of a pair of young sons, although it is also a little difficult to listen, but at this time he still understands the key to what Guan Qiu said, and he raised his eyebrows and said bluntly: "So, you speculate that the length and period of this single pendulum are written in the vertical opening number in the "New Edition of Ge's Arithmetic"? ”

"yes, it's hard, when I first started learning, I almost felt like my head was going to explode. But practice makes perfect, and I now know how to open a root number. However, the pendulum length calculated by the open root number cannot be copied, because the single pendulum vibration formula is ideal, and Brother Zhang said that the gravitational acceleration is actually an estimate, and there are slight differences in different places, and it needs to be adjusted......"

Listening to Guan Qiu's endless talk, the fourth prince peeked at everyone below his father, and saw that everyone began to be at a loss. At that moment, he, who had been feeling a little sorry for himself recently, suddenly relaxed. My father doesn't know much, let alone him?
