"Back to the saint, yes, in my village, no matter whether it is a boy or a girl, you have to go to the school to read and write, but I still need to go back and think about what is taught." Fang Jing didn't dare to say too much, after all, there were too many things that had not been completed, not to mention that the teaching materials were also a big thing.

"Okay, good, boys and girls should be enrolled in the hall, Fangjia Village is doing well, doing well." Li Shimin laughed, perhaps in his heart, he already agreed with the practice of Fangjia Village, but he couldn't be too written, who knows if it was written, it would not be attacked by those literati and Confucian scholars.

"Sir, in that case, can I send them to the Fang Family Academy as well?" The queen also agreed in her heart.

But what I think more about is whether I can send my daughters to the Fang Family Academy to enroll, in fact, it is nothing to send my daughters to the school, but if you really want to send a large group of royal princes, it is estimated that the Fang Family Academy may become the object of attack.

"Back to the saint, queen, in fact, the royal family really wants to send the prince and princess to our family school, it's nothing, but I'm afraid that there will be a lot of inconvenience in this court, you see how it is, send a few princes and county lords to our family school to study for a year or two to try, if the holy queen can't pass the exam, and then go back to Chang'an, this can also avoid court criticism."

Fang Jing just didn't want these princes and princesses to go over, but she couldn't lose the face of Li Shimin and his wife, which would also lose the face of the royal family, after all, everyone had mentioned it, so you can't refuse them all.

Fang Jing sat still, looking at Li Shimin's family, let them go, which ones to send, it is not Fang Jing's turn to be the master, Li Gaoming is the crown prince, it is impossible to go, at most send a few princes and county lords who are not favored.

As it got late, Fang Jing had no choice but to leave, and was sent to an official post by the guards to rest, this was also the first time Fang Jing stayed in the official guest house, the luxury was unimaginable, it was completely a high-end hotel furnishings, and there was a world of difference from the guest house where ordinary civilians lived.

In the dead of night, Fang Jing lay on the bed, but he couldn't sleep, thinking about the construction of the Fang Family School in the back, as well as teaching and other things, and he had no clue about it.

Fang Jing just wanted to build a school, but he didn't feel that there were so many things behind him, and it was beyond what he thought at the time.

The first guarantee is that Fangjia Village has a school, which is easy to solve, and the second is to ensure that the students are enrolled, Fang Jing didn't have any idea at first, there are so many children in Fangjia Village, there must be a lot of children, and the third is to ensure that the teaching materials, if the teaching materials are in accordance with the normal progress, that is, please ask two gentlemen, all teaching matters are decided by Mr., but this is also what Fang Jing does not want to see, Confucianism, there is no good or bad saying, but you can't teach too much, respect teachers and filial piety, Courtesy, righteousness, honesty, filial piety, faithfulness, etc., are very good.

The fourth guarantee is the various miscellaneous studies taught in the future, which is also what Fang Jing thought about at the beginning, teaching some mathematics, physical geography, animals and plants, and physical phenomena by herself, but now she is disrupted by the ideas of Li Shimin and his wife.

If you really want to send a few princes and county lords to study in the Fang Family Academy, then their food and accommodation are all a problem, could they all gather in Fang Jing's house, that Fang Jing is so annoyed that this large number of little babies is annoying, so he can only build a residence, and let Li Shimin send two subordinates, and the rest, hehe, then they can't help it.

After a night, Fang Jing got up from the bed with panda eyes, thinking that he would go to Yiguo Mansion today to have a look, no matter how bad it was, he would have to visit, after all, he had to walk around after coming to Chang'an, although he didn't have too much friendship, but he only knew such a family.

After washing, Fang Jing went downstairs, but he saw the two guards who escorted him over to the official post yesterday, trotting over to meet Fang Jing, looking very careful.

"Sir, today I will take you to see King Yue." The guard stood up respectfully and whispered to Fang Jing.

"King Yue? Blue Sparrow? Fang Jing's head was a little confused, she originally planned to go to the Yiguo Mansion today, but then she thought that she had said yesterday that she was going to see what experiments Qingque was doing, okay, it can only be like this, Yiguo Mansion, it's not too late to go again in the afternoon or tomorrow.

Fang Jing followed the two guards and walked towards a place in Chang'an City, and came to the door of a mansion, but saw several guards guarding in front of the mansion, thinking that this was the residence of King Yue.

Fang Jing remembered that the history books said that Li Tai had stayed in Chang'an Palace for a long time and had always refused to surrender, but he didn't expect that after one of his classes, he wanted to be a scientist.

The two guards approached the gate and said something to the guard door, and then the gate of the mansion opened, welcoming Fang Jing into the courtyard, and a subordinate in the mansion had already trotted to inform King Yue.

"Brother Jing, why did you come to Chang'an? I want to go to Fangjia Village to find you, but my father and mother won't let me go, go, go, go, just when you came, look at what I made. Qingque heard the report from the next person that Fang Jing was coming, and immediately ran over to see Fang Jing.

Qingque is an anxious person, as soon as he saw Fang Jing, he had to take a look at what he was fiddling with, Fang Jing came over this time, he must have wanted to take a look, but he was stunned by Qingque's anxious appearance.

As a prince, if he is seen by those court ministers, he will inevitably be attacked, according to the history books, when the court minister Wei Zheng is a direct minister, as long as he is not used to seeing it, he must always admonish, if the current Qingque is seen by that Wei Zheng, it is estimated that there is no good fruit to eat.

"Qingque, what are you anxious about? I can't run again, didn't I hear your father and mother say that you were doing some experiment yesterday, and I'm not here today? Fang Jing hurriedly grabbed the little fat man, he was a tall man, standing with this little fat man, he felt that his image was all lost, and there was nothing left.

"This ...... Okay, Brother Jing, I can tell you, after you talked about the effect of force last time, I tried many times, I'm not doing an experiment on the effect of force, I find that I don't understand more and more, today, Brother Jing, you must teach me some knowledge, so that I can understand how this force comes from. ”

Qingque saw that Fang Jing was not in a hurry, but she was so anxious that she couldn't do it, but she could only suppress the impatience in her heart and talk to Fang Jing patiently.

"Let's talk about it here, I don't know what experiments you're doing, but, listen to your mother, but it cost a lot of money, right?" Fang Jing asked Qingque.

"Hehe, I don't have much money, I can only ask my mother for some, it just so happens that I have reached the age of opening a mansion, so I chose this mansion and tried to do some experiments, but, Brother Jing, how can the effect of that force be produced? And how do you control it? ”

Fang Jing looked at this little fat man, and sighed in his heart, this little fat man really has the potential of a scientist, three sentences are not far from the industry, this is, he doesn't even talk nonsense, he wants to return to the original topic when he turns the corner, he wants to figure out what force is, how it is generated, and how to support and control it.

Qingque took Fang Jing to the inner courtyard, good guy, where can you still put your feet in this inner courtyard, there are stones, wooden barrels, wood, and even iron everywhere, there is a pool not far away, and there are a lot of sand and stones, but there are a lot of people in this inner courtyard who are helping, and I don't know what this Qingque is doing, just doing an experiment, making such a big formation, I don't know if Li Shimin will beat him after he knows about it.

"Brother Jing, you see, the waterwheel on the edge of the pool is built according to my ideas, but it still can't be driven by water, I've been thinking about whether I can let the upstream water rush down to drive this waterwheel, but I can't find a way, and the upstream water can't take my waterwheel, and I don't know what went wrong?"

Qingque pointed to a waterwheel with a diameter of nearly two meters on the edge of the pool, and said to Fang Jing, Fang Jing raised his eyes and looked at these four different waterwheels, he didn't know how Qingque designed it, or this thing was a fake handle, the impact of the upstream water flow was enough, after all, the water level in the pool upstream was nearly two meters high, but this waterwheel, there was an idea in the design, it was too big, forget it, don't mention it, it was a fake handle.

Fang Jing raised his legs and stepped over a lot of materials, and then came to the side of the waterwheel, looking at the big waterwheel, looking at the upstream water flow, if he wanted to drive such a large waterwheel through this water flow, it was completely impossible, and the impact force could only be established on the appropriate size of the waterwheel, otherwise it could only be used as an ornament.

"Qingque, this waterwheel is too big, there is no problem with the water flow, you can make a model first, and then design according to the size of the model, and pay attention to the size of the water flow, the higher the water level, the more urgent, in order to have a greater impact, then the effect of this force is relatively greater."

"Moreover, your waterwheel, but also according to the impact of the water flow to design, the water flow is slow, you design smaller, the water flow is fast, you can design larger, on your water flow impact, can only make your waterwheel half smaller, it is estimated that it is about the same, but the sleeve shaft of your waterwheel is best made of iron, but also polished and smooth, reduce the resistance of friction, you use wood to make the sleeve shaft, or forget it."

Fang Jing pointed out the problem with this waterwheel, I think Qingque should understand.

"Brother Jing, I'm already working on this set of cylinder axles, but this waterwheel will be reduced by half, isn't that too small, I spent a lot of money on it." Qingque understood, but it was a pity that his waterwheel cost money.

"Experiment, play is money, play is technology, no money, no materials, no materials, there is nothing to experiment, then there is no technology, the experiment is not a success, maybe you have to hundreds of thousands, or even tens of thousands of failures, to find the only way to succeed, this is scientific experiments, so experiments, are built on money." Of course, Fang Jing understands very well, if you don't have money, what kind of experiment are you doing, you don't have money, go sell yourself, anyway, you are a prince, this identity is there, it's really not good, just lie at the door of the door of the country's duke's house, and if anyone doesn't give a thousand children and eight hundred yuan, don't get up.

"Okay, then Brother Jing, is there a better way for this sleeve shaft?" Qingque wondered if she could get Fang Jing to provide her with a design idea.

"Bring pen and paper." Fang Jing didn't talk nonsense, just go straight to work.

Fang Jing took the brush and drew a bearing pattern from his previous life, as for how to solve this rolling ball, it was a matter of Qingque, Fang Jing would not give him a way, after all, Fang Jing only knew a rough idea, not to mention that this little fat man didn't have an uncle? Didn't the little fat man's uncle's family open an iron mine and practice iron? Are you afraid that there will be no craftsmen to figure it out? I don't think it's a bad person.

"Brother Jing, is this a sleeve shaft? So how do you get this ball in? If it all rolls together, won't it be impossible to move? The little fat man took the pattern drawn by Fang Jing, looked at it for a long time, and didn't understand the sleeve shaft drawn by Fang Jing, so he stared at Fang Jing and asked, but he didn't understand in his heart, how could such a sleeve shaft rotate.

"Qingque, I only paint, don't say, don't do, the rest is up to you to think, to verify, to understand, I say too much, you have no motivation to research, why not do it yourself? What's more, wouldn't it be better if you could ask a craftsman to verify it? Fang Jing is just like an enlightened teacher, do you really want to tell him word by word? Doesn't research just need to be done step by step, it's too fast, but it makes people lose the fun, not to mention, the deepest thought in Fang Jing's heart is that he doesn't want to change Datang too much by himself, and it is enough to affect a small number of people.
