Steel Dynasty - Chapter 236

[Chapter 236 Saltpeter and Lead Ore]

In the school, everyone looked at Xiao Ming, including Luo Xin with great expectations.

The artillery in Qingzhou now belongs to smoothbore artillery, that is, direct-fire artillery. In ancient times, firearms were smaller versions of artillery. Because of this, the principle of three points and one line also applies to firearms.

However, these three points and one line do not mean that you can just install a front sight and a rear sight. Different firearms have different front sights and rear sights, which all need to be tested. After all, the power of different artillery and the weight of the shells are also different.

Therefore, his artillery also needs to obtain data after testing before installing accurate sights and rear sights.

“This is the principle of parabola. The cannonball will be affected by gravity when it is shot out.” Xiao Ming said.

When he said this, everyone in the school looked confused.

Looking at the confused faces, Xiao Ming suddenly felt tired. This was the purpose of opening the school. Luo Xin could not be taught this in three or two days.

First he had to teach them addition, subtraction, multiplication and division, and then he would start with basic physics and reach the second grade physics level. He estimated that even with the high quality of his technology crystals, it would take close to a month to teach them. Let people like Luo Xin learn how to calculate the impact point and complete the front sight and rear sight test.

Of course, he would not sell the cannon with the front sight and rear sight, but would keep it for himself. Once he had the front sight and rear sight, it would be a technological upgrade.

When the two armies confront each other, the advantage of this artillery will be immediately highlighted.

“Your Highness, we don’t understand what you are talking about.” Luo Xin is a military commander after all, and he also has a headache with this knowledge.

“You will understand once you learn it.” Xiao Ming ignored Luo Xin. He was not going to talk to Luo Xin about the theory of a round sky and a round earth. Anyway, this guy walked on land, so it was of little use to learn it, but it was more useful to Yue Yun. I have to say this. Fortunately, Yue Yun is teachable and much better than Luo Xin.

Then he started with basic mathematics and wrote basic Arabic numerals on the blackboard. In future voyages, Yue Yun would also need to perform mathematical calculations to determine the orientation, so he also had to learn this knowledge.

Xiao Ming basically spent the rest of the day in school, from simple Arabic calculations to addition and subtraction within ten, to more complex calculation methods.

Because they were all adults and had the initiative to learn, the afternoon course was quite effective, and because of the effect of the technology crystal, they remembered most of the content.

In the evening, Xiao Ming asked Lu Tong to arrange food and lodging for Yue Yun and others, and told Luo Xin to come every afternoon to listen to the lectures before returning to the palace.

At this time, the sky was already a little hazy and dark. He was about to go back when he suddenly saw a person walking hurriedly from the gate of Bowen College.

“Big rich!” Xiao Ming saw this person clearly and said in surprise.

The person coming was Qian Dafu. When he saw Xiao Ming, Qian Dafu immediately said: “Your Highness, the saltpeter mine has finally been found, and we also found the lead mine!”

“What, really?” Xiao Ming was overjoyed.

“Yes, Your Highness, we finally found it.” Qian Dafu used to be a fat man, but now he is dark and thin. He looked excited at this time.

Xiao Ming was equally excited. He said: “Great, Dafu, you have made great contributions.”

“As long as His Highness’s affairs are not delayed, I will be happy. As for the credit, I really don’t care.” Qian Dafu Said with a smile.

Xiao Ming was moved in his heart. Qian Dafu was a person he completely trusted, so he gave him the responsibility of prospecting.

What he lacks now is resources.

“Let’s go back to the palace and I’ll ask the kitchen to prepare a big meal for you.” Xiao Ming laughed.

After returning to the palace, Xiao Ming asked the kitchen to prepare food while he and Qian Dafu went to the main hall and asked about the saltpeter mine.

“Your Highness, this mine is really hard to find. We have been searching for a whole month at the place roughly mentioned by Your Highness, but we found nothing. Does Your Highness know how we found it later?” Qian Dafu said.

Xiao Ming shook his head.

“At that time, we were too far away from the nearest village to go back, and we had no food. Several soldiers discussed going into the mountains to hunt. Unexpectedly, when we were chasing a hare, the hare suddenly got into a cave in the woods. “When several soldiers entered, they immediately discovered that there was saltpeter in the cave.” Qian Dafu was very excited.

Qian Dafu said it very simply, but Xiao Ming could understand the difficulty of prospecting.

At this time, the saltpeter mine had made progress, and neither the King of Shu nor the court could threaten him with this.

“It seems that I want to thank this rabbit.” Xiao Ming looked happy and asked, “Where is this lead mine?”

Qian Dafu took a sip of water and said, “The lead mine is quite far from Qingzhou. In Yi “

Yizhou is about two hundred miles away from Qingzhou, which is indeed a bit far. It’s still far,” he said. “It’s better than nothing. But is there still no progress in this tungsten mine?”

Qian Dafu shook his head. , said regretfully: “No tungsten ore has been found yet, but Your Highness, why do you have to look for this tungsten ore?”

“Because the smelting of tungsten ore and wrought iron can make the material harder. If there is tungsten ore, this king will We can try to produce tungsten alloy, so that the manual lathe will have qualified tools, and then I will be able to create a magical machine,” Xiao Ming said, and the mysterious machine in his mouth was naturally a steam engine.

Qingzhou’s population was too small. Once the steam engine became available, he could use steam engine power to replace the lack of manpower.

More importantly, this can greatly increase the steelmaking capacity of the steel mill.

Qian Dafu seemed to understand. He smiled and said: “In that case, I will focus on looking for tungsten ore.”

The saltpeter mine solved the problem of gunpowder, and the lead mine solved the problem of cannonballs and bullets for future firearms. Xiao Ming was very worried .

Block, but next he has to think about preparing for the next technological upgrade.

And this is where the lathe really shines.

“There’s no rush. You need to rest for a while before leaving this time. I don’t want to tire you out.” Xiao Ming said.

The two talked for a while, and then Luluo walked in and said, “Your Highness, the food is ready.”

“Let’s go and eat. I asked the cook to prepare your favorite smoked pig’s trotters.” Xiao Ming smiled.

When he mentioned this, Qian Dafu suddenly laughed, “Your Highness, this is what I like, this pig’s trotters is worth it no matter how tired I am.”

Xiao Ming laughed when he heard this, Luluo also covered his mouth and smiled, and returned to Qingzhou After that, the girl gradually recovered.

Speaking of which, Xiao Ming also likes to eat smoked pig’s trotters, but there is no such dish in the country of Chongqing. He taught the cooks to make it carefully. Qian Dafu has been addicted to it since the first time he ate it. The smoked pig’s trotters make my mouth water.
