Chapter 591

PS: I'm sorry for the delay in updating after the resignation. Today, with the intervention of the labor bureau, the salary was settled, and the snail was completely liberated. Next, the snail burst continuously to compensate you.

The candle in the bedroom was flickering, and the night outside was dark.

After pondering for a long time, Xiao Ming said: "I have already had a concern in my heart, but now some people in the women's college have mentioned that you should also give proper guidance. We must not let some reckless remarks spread openly among the students."

"Yes, your highness." Fei yue'er said softly.

Xiao Ming nodded. Disrupting the internal affairs of the country has always been the Western specialty. He does not want to fall into civil strife before the great Chongqing is revitalized. When he makes the great Chongqing strong and rich enough, it is not too late to try the reform of the political system.

Moreover, even if this trend of thought is spreading among the students, the vast majority of the people still don't understand it. If there is a political reform at this time, the vested interests are still the students and merchants, and the people can't get any advantage. In this case, why should he be impatient? After all, for him, the basis of his rule is the people.

After chatting for a while, they went to bed with Yi. The next day, Xiao Ming went to the yam. Yesterday, Li Kaiyuan had already sent sweet potatoes to the yam because it was too late. Pang Yukun and Fiji didn't see each other.

Pang Yukun and Fijian are eating roasted sweet potatoes when he arrives. The room is full of roasted sweet potatoes.

"Your Highness, this sweet potato is delicious." Pang Yukun's mouth is full of sweet potatoes, and Fiji keeps eating them.

Xiao Ming said with a smile, "you've also eaten this sweet potato. The following is the cultivation of sweet potato seedlings. You go to kuiwu for this matter. He knows how to cultivate sweet potato seedlings after studying in Bowen College for such a long time."

"Yes, your highness." Pang Yukun fills his stomach with the last sweet potato.

After a pause, Xiao Ming continued: "by the way, this will be the autumn harvest soon. You should ask the local government to organize the militia to strengthen the patrol in the field to prevent the food from being burned by the enemy."

Pang Yukun's face became more serious. Three years ago, it seemed that he was still vividly remembered. At that time, in order to destroy the Cangzhou war, the haos burned wheat fields, and Xiao Ming was almost killed.

Now there is a direct confrontation between Qi and Wei, and similar things may not happen again. It is for this reason that Xiao Ming reminds us.

Pang Yukun nodded, "I'll send someone to inform the prefectural government later. Now every village has a militia. It should be better this time."

Fiji has always had a complex sense of the militia in the village, because in his opinion, it is too late for the government to collect civilian weapons. Instead, Qingzhou is organizing the people's own armed forces.

However, he gradually understood that the reason for this was based on people's support for Xiao Ming and their recognition of the feudal state.

They were talking about sweet potatoes and autumn harvest when an explosion came from the direction of Bowen college.

Pang Yukun said: "this blog college has not seen a laboratory explosion for a long time. What's wrong this time?"

Xiao Ming was also puzzled. Lu Tong didn't seem to have done any dangerous experiments during this period of time. However, since there was a stir, he had to go, so he said, "when you deal with government affairs, I'll go and have a look."

After that, he took Zhao long and Zhao Hu to Bowen college. As soon as he entered the college gate, he saw puffs of smoke rising in the direction of the chemical laboratory.

Take a few steps and he's on his way.

"What's the matter?"

Lu Tong is also outside the lab. Xiao Ming asks directly.

Seeing Xiao Ming coming, Lu Tong looked sad. He said, "Your Highness, a student came across a bottle of sulfuric acid and nitric acid. In a panic, the boy took off his clothes and wiped them. Then he dried them with fire. But he didn't want that the clothes burned to ashes and ignited the explosion in the laboratory."

Xiao Ming looked strange. He asked, "doesn't he know that the clothes soaked in the mixture of sulfuric acid and nitric acid have become smokeless powder?"

Lu Tong said: "this boy is a student who just entered the school. He just started in the laboratory. He doesn't know what smokeless powder is."

Speaking of smokeless powder, Lu Tong suddenly sounded something, he said: "Your Highness, the laboratory is developing smokeless powder these days, but this smokeless powder is very unstable, this problem has not been overcome, so the lower officer did not report to your highness."

"This is nothing. What happened to the trainee?" Xiao Ming said.

Lu Tong felt relieved and said, "I'm burned, but it's not a big problem."

Xiao Ming nodded. In fact, the principle of smokeless powder is very simple, that is, soak the cotton in the mixture of concentrated sulfuric acid and concentrated nitric acid for ten minutes and take it out to dry in the shade.

However, the firewool produced in this way, that is, smokeless powder, is very unstable. It needs to be treated with camphor, graphite, alcohol ether mixed solvent and rolled into shape. Otherwise, this kind of powder is easy to explode before it is launched.

Now Lutong is faced with the problem of alcohol ether mixed solvent. If this problem is solved, smokeless powder will be used as the upgraded version of black powder and become the gun propellant, which will improve the range of bullets and shells.Originally, Xiao Ming had been indifferent to the development of collodion, but now he had to ask about it. As he guessed, Lu Tong's problem was the stability of collodion.

At present, Xiao Ming has no way to solve this problem, so he can only let the laboratory try to synthesize it. After all, this kind of thing is not so easy to make, not to say that it has exceeded the technology of Dayu for many years, or even more than 100 years in the West.

However, Lu Tong's courage to develop collodion now shows that he still has confidence in smokeless powder. After all, as long as ethylene glycol and propylene glycol are synthesized, there will be basically no problem with alcohol ether solvent.

Of course, Xiao Ming will think of a way to solve this problem for Lu Tong. After all, no matter how they learn from Lu Tong, they can't have as many ideas in his mind. However, Lu Tong is still a little impatient. The technical level of huomian has exceeded that of the West for a hundred years, and it's not so easy to get there in one step.

"Don't rush for quick success and instant benefit in this matter. Even if you have synthesized ethylene glycol and propylene glycol, you can't mass produce collodion with the current output of sulfuric acid and nitric acid. Therefore, your most important task now is to realize the industrial production of synthetic chemicals, and it's time to form industrial mass production of three acids and two bases, otherwise the chemical industry will stop at the same level." Xiao Ming said seriously.

Lu Tongwen was a little ashamed. He admitted that he had some ambition in this period of time, because the steam engine of physics college stimulated him.

"Your Highness, I'm wrong." Lu Tong was embarrassed.

With a smile, Xiao Ming said, "you have to be down-to-earth in learning and production. You have to go step by step."
