"Now the green ore in front of you is called green alum, I have taught you these, we did not have experimental instruments before, can not operate, now with these chemical instruments, today this king will show you how to use green alum to prepare sulfuric acid, after this experiment, you have to put into the production of sulfuric acid. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info," Xiao Ming said.

Now that this group of people have mastered the basic knowledge of chemistry, in Xiao Ming's opinion, at least the junior high school level of chemistry knowledge is available, and it is not a problem to put this knowledge into production.

The purpose of knowledge is application, and after all, this knowledge must be used in production.

"Yes, Your Highness."

Lu Tong and others are full of confidence, and now three or four months have passed. During this period, they didn't have to worry about food, clothing, housing and transportation, they were all focused on learning, Xiao Ming's chemistry teaching opened up a new world for them, and they never thought that there was this kind of magical knowledge.

Every time Xiao Ming taught, these atomic structures, molecular structures, and the appearance of various rare metals seemed to be presented in their minds, making them understand quickly.

Nodding with satisfaction, Xiao Ming put the green alum into the test tube, and the other end into the water, and then used the alcohol lamp to heat it up.

Nowadays, it is possible to purify alcohol and produce glass bottles, so this alcohol lamp is naturally no problem, which is also one of the conditions for chemical experiments to be carried out.

Lu Tong and the others stared at Xiao Ming's operation for a moment, for fear of missing anything.

Now they are eager to put what they have learned into practice, but there is a shortage of various chemical materials, and it is difficult for a clever woman to cook without rice.

With the addition of alcohol, the color of the alum slowly changes from green to reddish-brown, which proves that the alum has successfully decomposed.

After a class, under the supervision of Xiao Ming, Lu Tong and others also followed suit and successfully prepared sulfuric acid, but even if everyone added up, it was only a little bit prepared.

"Your Highness, let's do the rest by ourselves, after studying for so long, we can't let Your Highness teach it in person every time, we can also explore it ourselves, Your Highness only needs to provide us with materials."

At the end of the teaching experiment, Lu Tong came forward and said to Xiao Ming.

Xiao Ming was relieved that these students finally had this awareness, thinking that the modern motherland was also building its own powerful industrial system from scratch, relying on their own exploration.

Now that he is responsible for providing knowledge, he also has to believe that these students can also do wonders.

He said: "If you have ambition, in this case, I have focused on teaching the knowledge of three acids and two alkalis, you want to find a way to engage in production, you need silver, just tell me if you have manpower." ”

Lu Tong nodded excitedly, from a slave to his current privileged life, this was all given by King Qi.

They are people who know how to repay their kindness, and at the same time they want to make their own contribution to their hometown, so that the people of the fiefdom will no longer suffer humiliation.

Xiao Ming was relieved in his heart, he saw an emotion called feelings in Lu Tong's eyes.

It is the feeling of this kind of thing that allows a person to give up his own interests and dedicate his life to the interests of the public, and when the modern motherland is poor and white, it is precisely because of these people that the country will become stronger step by step.

This is a noble character, this kind of character he has seen from Pang Yukun, from Lu Fei, from Chen Wenlong and his son, and also from Fan Zeng.

It is because of this character that they will go out of their way to support their own changes and make their fiefdoms richer and stronger.

He needed people with this character, and these people were the cornerstones of the fiefdom.

Patting Lu Tong on the shoulder, Xiao Ming gave him an encouraging look, and told him to come and ask if he didn't understand, and then leave Bowen Academy, what he is teaching now is enough for Lu Tong and these people to toss for a long time.

And Xiao Ming gave him a plan, this plan is the steps of chemical production, from simple to difficult, step by step to realize the chemical industry.

Once the chemical industry improves, it can promote each other with the steel industry, and then he can find a way to get the alloy out.

The first thing is naturally tungsten steel, once he has tungsten steel, he can make qualified tools, and hard tools can be used to formally process various metal parts.

It was a small leap forward for industry.

However, although the idea is good, it is still difficult to implement, the first one is to find wolframite and scheelite, which is not as easy to find as coal and iron ore.

In fact, at this time, as long as it is not an open-pit mine, it is very difficult to find and mine.

Several of the mines that Qian Dafu found were shallow mines, and some deep mines could not be found now, after all, it was one thing for him to master the map, and it was a matter of understanding the accurate search.

He doesn't have a satellite location.

Thinking of this, he sighed, now he can only rely on luck, if you are lucky, you may be able to find tungsten ore soon, and if you are unlucky, you can only wait.

Once he has tungsten ore, he can use sulfuric acid to extract tungsten to refine alloys.

The industrial base can only be done step by step, according to the map, and agricultural production is as important as industry, and this Xiao Ming does not dare to be careless.

Thinking all the way, he went straight back to the palace, and as soon as he arrived at the door, he saw Aster with a hurried expression and crashed into his arms.

Xiao Ming was knocked and stumbled, and instinctively hugged Aster so that he didn't fall, and one hand was grabbing Aster's buttocks.

"Ah......" Aster first exclaimed, and saw that it was Xiao Ming who stopped her voice, but when she felt that hand pinched it a few times, she suddenly turned crimson.

"Your Highness, you ...... in broad daylight," Aster said angrily.

Xiao Ming let go of his hand with a smile, recalling the meaning of Aster's words, if it doesn't work in broad daylight, is it okay if the night is dark and the wind is high.

Aster looked around nervously, and was relieved to see that no one saw it, after all, the defense of men and women is greater than the sky, and if people see it, it would be ashamed to die.

But she didn't blame Xiao Ming, during this period of getting along, she and Luluo gradually became familiar with Xiao Ming.

knew that sooner or later she would also be Xiao Ming's woman, and Xiao Ming's personality was likable, but she didn't care about Xiao Ming's actions.

"This is what you bumped into the arms of this king, how can you blame this king?" Xiao Ming said lazily.

Aster sighed helplessly, and suddenly her expression became nervous again, and she said: "Your Highness, I almost forgot, I was in a hurry to find you, and Niangniang sent a letter to say that Princess Pingyang will be in Qingzhou soon, let you take care of it more." ”

"Princess Pingyang?" Xiao Ming almost felt dizzy, "Why did she come here." ”

"It's not for perfume, soap, these things, now with glass, the letter said that the glass sent by His Royal Highness to Chang'an has caused a sensation in the entire palace!"
