Chen Xinhua immediately took out the chemistry textbook that never left his pocket from his pocket, flipped to the position of the periodic table at the end, brought it to Zhao Zhen, pointed to it and said: "Your Majesty, look, the circles drawn by the ministers on this have all been made, and the dotted ones are a little eyebrows, and the others just don't have a clue, especially the two or three rows at the back, and the ministers don't know what the situation is at all!" ”

Zhao Zhen took the book from his hand: "Show me the book, what's the matter with the stars you draw on it?" ”

"Back to the emperor, those are the ministers who have found it but there is no way to completely purify it, the more stars, the lower the purity......"

"I see! I see you've found quite a few! ”

"Emperor Xie praised, the ministers are just practicing the knowledge you taught, and there are still many things that cannot be understood, and the ministers are ashamed!"

"I still say the same thing, take your time, don't panic, and take one step at a time. In addition, you have to put education in the first place, and only when there are more people in the teaching department can this knowledge be carried forward! ”

"Obey the teachings! The ministers and others are now doing experiments while leading students, and the entire Royal Academy can still pick out a lot of perceptive children, and the ministers believe that they will be able to adapt to these new knowledge in a few years. ”

While following Chen Xinhua Yinghe, the others wrote and drew on their small notebooks, as if they wanted to record every word the emperor said.

Zhao Zhen nodded, smiled and said: "That's good, I also plan to open an academy in each part of the country, but only teach some simple basic knowledge and some common sense of life, and then select the outstanding ones from among them to enter the royal academy for further study." Therefore, the Royal Academy will develop into the high-end field in the future, so let's give you a breath first, and you should be a little prepared. ”

"Your Ministers obey!"

After shopping for a long time, Zhao Zhen also felt that his feet were a little swollen, so he found a chair and made it: "It's enough to go shopping for half a day, let's sit down and rest for a while." I would like to take this opportunity to let Chen Aiqing and them tell you about their gains! ”

"Emperor Xie!" After everyone thanked them, they sat on the ground regardless of whether the floor was dirty or not, and dozens of people crowded Chen Xinhua's office.

Zhao Zhen saw that everyone was seated, and then said to Chen Xinhua: "Taking advantage of this rest time, Aiqing will tell you how to get these things, which will also open everyone's eyes...... Well, I see that the hydrogen element on your book is circled and there are no stars, presumably Aiqing is more satisfied with its purity, so let's talk about it first! ”

"Obey the order!" Chen Xinhua arched his hand towards Zhao Zhen first, then got up and came to the small blackboard he usually used, picked up chalk and drew on it.

Chen Xinhua pointed to the blackboard and said, "Your Majesty, colleagues, please take a look!" Everyone in this room should know that hydrogen is the first and lightest of the periodic tables. The chemistry book taught by the emperor also clearly records the characteristics of hydrogen and some simple production methods. But this 'simplicity' is not simple for us, and in the face of this strange thing, the ministers have never been in contact with it, and they do not have the conditions to produce it.

It wasn't until the emperor used the electric show for the first time in the Spring Festival Gala last year that the minister thought of using electricity to make hydrogen, and the minister knew that one of the ways was to put electricity into the water to produce hydrogen and oxygen at the same time. Then the gas produced by the positive and negative poles is introduced into two upside-down water tanks through glass tubes, and the bottles filled with water are filled with hydrogen and oxygen, so that the water in the bottles can be emptied, so that pure hydrogen and oxygen can be collected......"

Hearing this, Zhao Zhen suddenly stopped him and asked, "Aiqing is saying that this hydrogen is made from my hand-cranked generator?" Didn't there be any accidents in the process, such as explosions or something? ”

"Your Majesty! The ministers did use your generator at the beginning, and as you said, the hydrogen collected by the ministers was led out through the glass conduit and exploded when it was burned, but fortunately, the amount was relatively small, and the explosion was not very powerful. ”

"And do you know why it exploded now?" Zhao Zhen then asked.

"Back to the emperor, the minister has now figured it out, and this is thanks to the gentleman, who pointed out that your generator is alternating current. Therefore, when electrolyzing water, hydrogen and oxygen will appear alternately in these two stages, so the gas collected in the bottle is impure, and it will naturally burn violently in case of open flame, resulting in an explosion. Later, the gentleman changed the brush design of your generator to alternating current to direct current, and then he came up with pure hydrogen and oxygen......"

Zhao Zhen gave Wang Shenli an encouraging look: "Well, you have all done a good job, various disciplines are originally complementary to each other, and you usually communicate more when you have nothing to do." Xinhua, you can briefly tell you about some of your company's achievements! ”

"Yes, Your Majesty! In addition to trying according to the emperor's textbooks, the minister and his colleagues also looked through a large number of ancient books, and we found that in fact, there are many things that our ancestors have already made, but they have not made good use of them. For example, arsenic stone, we all know that it can be used to make arsenic, in fact, it also has a big effect, if you add it when smelting copper, then you can make white copper. Although we have not yet fully understood the properties of cupronickel, we believe that this is one of the alloys mentioned by the emperor, and one day it will be found useful.

For another example, the boron on the periodic table has actually been used in Tibet, and those goldsmiths have used it as a co-solvent, and we have also tried to use it in steelmaking, and the effect is really significant.

The only problem is that this kind of borax is relatively rare in our dynasty, but there are quite a few in Tibet! ”

Speaking of this, Chen Xinhua looked at Zhao Zhen, a trace of embarrassment flashed on his face, one by one advocating his own great wealth in the Central Plains, who wants to admit that this thing is not as good as Fanbang?

Zhao Zhen didn't care: "You don't have to be frustrated, I will order Gao Jixuan (the original transfer envoy) of Chengdu Prefecture to include this borax in the transaction project with Tubo." In short, I will buy whatever you lack, and even if you can't buy it, I will find a way to make it ours. I have just one request, all of you Aiqing strive to finish this periodic table as soon as possible! ”

"Do the holy thing!"

Zhao Zhen took the lead in standing up, and the others naturally followed suit: "I see that I have almost rested, so let's go to the Machinery Division with me to have a look!" ”

This time it was Wang Shenli's turn to lead the way, and when he entered the door, a big iron guy came into everyone's eyes, unlike in the past, it kept ringing non-stop, and it stayed there quietly today.

Wang Shenli touched the big steam engine, and the expression in his eyes was full of ups and downs: "Your Majesty, you see, it's this big guy, it took us a year just to get it out, but unfortunately we haven't been able to tap its full potential......

Zhao Zhen himself used to do this business, and he was able to understand his mood, but he just patted him on the shoulder and didn't say anything encouraging.

Wang Shenli indifferently walked in front of another big guy not far away, and looked at the iron guy in front of him, and a fine light flashed in his eyes: "Your Majesty, this is what the ministers have been tossing recently, guess what it does?" ”

Wang Shenli was rarely lively, of course Zhao Zhen had to give him face, so he stepped forward to take a closer look at the machine, and the others also swarmed up, surrounding Zhao Zhen and pointing at it.

The overall structure of this machine is not complicated, or rather very simple, at least intuitively. The biggest part of this machine is a big water wheel, which is installed in a ditch, but because the ditch is empty now, it stays quietly; On the bearing of the waterwheel there is a slightly smaller disc that is tightly connected to another enclosed cylindrical object with a rubber belt around it. Obviously, they wanted to use water to drive the waterwheel, and then to turn the contents of the closed cylinder.

Zhao Zhen didn't understand what they were trying to do for a while, until he saw two copper wires wrapped in rubber sticking out of the closed wooden barrel, and a bold conclusion suddenly flashed in his mind: "Aiqing, are you doing generators?" ”

Wang Shenli opened his mouth with laughter: "The emperor is wise! After reading the results of your hand-cranked generator and combining the knowledge in the book, he thought about giving it a try. In the beginning, we still used human power to rotate, but it was too strenuous and not sustainable, so we thought of switching to a water wheel, so that as long as the water flowed, we could continue to generate electricity. But now there are still some problems, I don't know if the coil is wrong, or the magnet is not strong enough, anyway, this electricity is not big...... I've electrocuted a chicken! ”

When Zhao Zhen heard this, his face darkened, and he was emotionally playing with this electric chicken, but he still knew that he didn't take people to play with electricity: "Electricity is still very dangerous, you all have to pay attention to safety, if something happens, I have to settle accounts with you!" ”

"What the emperor said is that the minister is very provincial, the minister just wants to tinker with the motor written in your book, it's not that he can't find electricity, so the minister has to ......" Wang Shenli had an aggrieved face, staring at Zhao Zhen pitifully.

"Alright! Don't act with me, I just don't want anything to happen to you, do you know how hard I have worked to train you? Remember how stupid you were when you were kids? Pay attention in the future, you know? ”

"Emperor Xie cares! Please rest assured that you must keep safety precautions in mind! "A group of people were very excited, scrambling to be the first to perform.

"Look at all of you are upset, learn more from other people's happy girls, see how quiet and calm they are...... Yay, what about glad? What about people? ”

Zhao Zhen and the big guy, you look at me, I look at you, I looked around, but I didn't see anyone.

At this time, Wu Ren seemed to remember something, and stood up alone: "Your Majesty, the minister thinks she should still be in the office of the gentleman?" ”

"Why?"

"Back to the emperor, when we were leaving just now, the minister saw that she was asleep in a chair, so he put a dress on her......" Wu Ren stated very calmly.

When Yan Su heard what he said, he wanted to press him to the ground immediately and hammer him, he had already heard that there were a few people in the emperor's sect who had abnormal brains, and now he saw that the emperor could come out of such a big thing, and he was speechless!

"Don't go and get her here!" Yan Su glared at Wu Ren angrily.

"Oh" Wu Ren responded very calmly, and then took small steps and left.

After a while, Xie Xinran followed Wu Ren with a red face, came to Zhao Zhen, lowered his head to avoid Zhao Zhen's scrutinizing eyes, and asked in a low voice, "Your Majesty, is this my turn?" Let's go! ”

Zhao Zhen didn't follow her, and deliberately bent down to stare at her: "Did you stay up late again?" Look at your two big black circles, didn't I tell you that girls don't work so hard, pay attention to taking care of their skin, and just let these guys go desperately! ”

There was a group of resentful eyes floating next to him, it's okay not to be so eccentric!

Zhao Zhen ignored them all, but continued to comfort others: "Why don't you go back and rest first, and I won't go to the medical department today?" ”

"No!" Xie Xinran suddenly mustered up the courage to pull the corner of Zhao Zhen's clothes: "Your Majesty, I just heard that you are coming to inspect, and you have been working overtime with your sisters for the past few days, and it was finally completed, can you not go!" ”

"Sisters? Still working overtime? What's going on? Zhao Zhen was very puzzled, and he went out to hang around, he hadn't been there for two or three months, it seemed that she had done something, and his eyes were strafing back and forth between Xie Xinran and Yan Su.

There is no way, at this time, Yan Su, who is the leader, will inevitably come out to resist: "Back to the emperor, you don't know, in the days when you were away, Miss Xie brought in a lot of people from the sons and daughters of the imperial doctor's family." The minister thought that they were all descendants of a medical family, and they knew a little bit about it, so they didn't object, and asked the emperor to forgive him! ”

"That's it? Good thing! Zhao Zhen said nonchalantly: "Xinran, tell me, what are you all busy with?" ”

Xie Xinran pursed his lips and smiled: "Your Majesty, you will know when you go!" ”

Zhao Zhen waved his hand: "Yo, I still know that I am selling off!" Okay, let's go! ”
