"The green ore in front of you is called green alum. I have taught you all these. We didn't have experimental instruments before and could not operate them. Now with these chemical instruments, today I will demonstrate to you how to use green alum to prepare sulfuric acid. After this experiment, you will need to invest in the production of sulfuric acid." Xiao Ming said.

Now this group of people have mastered basic chemistry knowledge. In Xiao Ming’s opinion, at least the junior high school level is available, so putting this knowledge into production is not a problem.

The purpose of knowledge is to apply it, and ultimately this knowledge must be used in production.

"Yes, Your Highness."

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

Every time Xiao Ming teaches, these atomic structures, molecular structures, and various rare metals seem to be presented in their minds, allowing them to understand them very quickly.

Nodded with satisfaction, Xiao Ming put the green alum into the test tube, and the other end was penetrated into the water, and then heated it with an alcohol lamp.

Now that alcohol can be purified and glass bottles can be produced, this alcohol lamp is naturally fine, and this is also one of the conditions for chemical experiments to be carried out.

Lu Tong and others stared at Xiao Ming's operation for a moment, fearing that anything would be missed.

Now they are eager to put the knowledge they have learned into application, but because of the lack of various chemical materials, it is difficult for a skilled woman to cook without rice.

With the addition of alcohol, the color of green alum slowly changed, from green to reddish brown, which proved that green alum successfully decomposed.

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

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

After the teaching experiment was over, Lu Tong came to Xiao Ming and said.

Xiao Ming felt relieved that these students finally had this consciousness. Thinking about the modern motherland, it also established its own powerful industrial system from scratch, and relying on it is its own exploration.

Now he is responsible for providing knowledge, and he also believes that these students can also create miracles.

He said: "I am determined. Since this is the case, I have focused on teaching all the knowledge of three acids and two alkalis. You can find ways to produce and need money. Just tell me if you have a manpower."

Lu Tong nodded excitedly. From a slave to his current wealthy life, this was given to King Qi.

They are people who are grateful and want to make their own contributions to their hometown, so that the people in the fiefdom will no longer suffer humiliation.

Xiao Ming felt relieved, and he saw an emotion called emotion in Lu Tong's eyes.

It is precisely the things like sentiment that allow a person to give up his own interests and devote his life to the interests of the public. When the modern motherland is poor and deserted, it is precisely because of these people that the country will become stronger step by step.

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

It is precisely because of this character that they will desperately support their own changes and make the fief more prosperous and powerful.

He needs talents with this kind of character, and these talents are the cornerstone of the fiefdom.

He patted Lu Tong on the shoulder, Xiao Ming gave him an encouraging look and told him to ask if he didn't understand, so he left Bowen Academy. What he taught now is enough for Lu Tong and others to struggle for a long time.

And Xiao Ming gave him a plan, which is a step in chemical production, from simple to difficult, and realizes the chemical industry step by step.

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

The first thing is naturally tungsten steel. Once tungsten steel is available, it can produce qualified tools, while hard tools can formally process various metal parts.

That was a small leap in industry.

However, although the idea is good, it is still difficult to implement. The first thing is to find black tungsten ore and sycamore ore. This tungsten ore is not as easy to find as coal mines and iron ore.

In fact, it is very difficult to find and mine the mineral deposits at this time as long as they are not open-pit mines.

The several mines Qian Dafu found were shallow mines, and some deep mines could not be found yet. After all, it was one thing for him to master the map, and this exact search was a matter of learning for a while.

He has no satellite positioning.

Thinking of this, he sighed. Now he can only rely on luck. If he is lucky, he may be able to find the tungsten mine as soon as possible. If he is not lucky, he can only wait.

Once tungsten ore is available, it can use sulfuric acid to extract tungsten to refine alloys.

The industrial foundation can only be followed step by step and followed the map. Agricultural production is equally important as industry, so Xiao Ming dared not be careless.

Thinking about it all the way, he went straight back to the palace. As soon as he arrived at the door, Ziyuan looked hurried and crashed into his arms.

Xiao Ming was hit and staggered. He instinctively hugged Ziyuan and did not fall down. He grabbed Ziyuan's butt with one hand.

"Ah..." Ziyuan screamed at first, and then she stopped the sound when she saw that it was Xiao Ming, but when she felt that the hand had pinched it a few times, her face suddenly turned red.

"Your Highness, you are in broad daylight..." Ziyuan said angrily.

Xiao Ming smiled and let go of his hand, savoring the meaning of Aster's words. If it is not possible to go into broad daylight, is it enough to be dark at night and high winds?

Ziyuan looked around nervously, and breathed a sigh of relief when she saw no one saw it. After all, the defense between men and women is greater than that of the sky, and it would be so embarrassing if people saw it.

However, she did not blame Xiao Ming. After spending time together, she and Luluo gradually became familiar with Xiao Ming.

I knew that sooner or later, I was also Xiao Ming's woman. In addition, Xiao Ming's personality was likable, but he didn't care about Xiao Ming anymore.

"This is what you bumped into my arms, how can you blame me?" Xiao Ming said lazily.

Ziyuan sighed helplessly, and suddenly her expression became nervous again. She said, "Your Highness, I almost forgot. I am in a hurry to find you. The Empress sends a letter to say that Princess Pingyang will be in Qingzhou soon, so that you can take care of it."

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