Iron Dynasty

In the school, everyone looked at Xiao Ming, including Luo Xin, who was also full of expectations.

Now the artillery in Qingzhou is a smoothbore gun, that is, a direct-firing gun. In ancient times, firearms were a smaller version 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 rear sight. The front sight and rear sight of different firearms are different, which all need to be tested. After all, the power of different guns and the weight of the shells are also different.

Therefore, his artillery also needs to be tested and then the data can be installed to install accurate sights and rear sights.

That's why the parabola is the principle. When the shell is fired, it will be affected by gravity. Xiao Ming said.

When he said this, the entire school showed a confused look.

Looking at the confused faces, Xiao Ming suddenly felt a little tired. This is the purpose of his school. This is not something that can be taught to Luo Xin in three or two days.

First of all, he has to teach them addition, subtraction, multiplication and division, and then start with basic physics. It is enough to reach the level of the second year of junior high school. He estimated that even with the high quality of his technology spar, it will take close to a month. Let people like Luo Xin learn how to calculate the impact point and complete the test of the crosshair and rear sight.

Of course, he will not sell the sight and the artillery with the sight, but keep it for himself. Once the sight and sight are available, it is equivalent to a technological upgrade.

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

His Royal Highness, we don't understand what you said. Luo Xin is a military general after all, and he has a headache with this knowledge.

You'll understand when you learn it. Xiao Ming ignored Luo Xin. He wasn't going to tell Luo Xin about the perfect world. Anyway, this guy walked on land, so it's not very useful to learn it, but to Yue Yun. It must be said that, fortunately, Yue Yunruzi can be taught, and he is much stronger than Luo Xin.

Then he began to talk about basic mathematics, and wrote the basic Arabic numerals on the blackboard. In the future sailing, Yue Yun also needs to perform mathematical calculations to determine the position, so he also has to learn this knowledge.

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

Because they are all adults and have the initiative to learn, the course effect this afternoon is quite good, and because of the role of the technology spar, they have memorized most of the content.

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

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

Da Fu! Xiao Ming saw this person clearly and exclaimed in surprise.

The person who came was Qian Dafu. As soon as he saw Xiao Ming, Qian Dafu immediately said, Your Highness, the saltpeter mine has finally been found, and we have also found lead mine!

What, really? Xiao Ming was overjoyed.

Yes, Your Highness, we have finally found it. Qian Dafu used to be a fat man, but now he is black and thin. At this time, he looked excited.

Xiao Ming was equally excited, he said, Great, Dafu, you have done a great job.

As long as the matter of His Highness is not delayed, the old slave will be happy. As for the credit, the old slave really doesn't care. Qian Dafu said with a smile.

Xiao Ming was moved for a while, this Qian Dafu was a person he completely trusted, so he entrusted him with the important task of finding mines.

What he lacks now is resources.

Let's go back to the palace, I'll let the kitchen prepare a big meal for you. Xiao Ming laughed.

Back at the palace, Xiao Ming asked the kitchen to prepare food, and went to the main hall with Qian Dafu to inquire about the saltpeter mine.

His Royal Highness, this mine is really hard to find. We searched for the place that His Highness roughly said for a whole month and found nothing. Does His Highness know how we found it later? Qian Dafu said.

Xiao Ming shook his head.

At that time, we were too far from the nearest village to go back, and there was no food to eat. Several soldiers discussed going into the mountains to hunt. Unexpectedly, while chasing a hare, the hare suddenly got into a cave in the woods. In the middle of the night, a few soldiers went in and immediately found that there was saltpeter in this cave. Qian Dafu was beaming.

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

At this time, the saltpeter mine has made progress, and neither the King of Shu nor the imperial court can use this to blackmail him.

It seems that this king has to thank this rabbit. Xiao Ming looked happy, he said, Where is this lead mine?

Qian Dafu took a sip of water and said, The lead mine is a little far from Qingzhou, near Yizhou.

Yizhou is about 200 miles away from Qingzhou, which is indeed a bit far. He said: It's far away, it's better than nothing, but is there still no progress in this tungsten mine?

Qian Dafu shook his head and said regretfully, The tungsten ore has not 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 can try to produce tungsten alloy, so that the manual lathe will have qualified tools, then this king can make a It's a magical machine. Xiao Ming said, the mysterious machine in his mouth was naturally a steam engine.

The population of Qingzhou is too small. Once the steam engine is available, he can replace the lack of manpower with the power of the steam engine.

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

Qian Dafu didn't seem to understand. He smiled and said, In this case, the old slave will focus on looking for tungsten mines.

Saltpeter ore solved the problem of gunpowder, and lead ore solved the problem of cannonballs and future firearms and bullets. Xiao Ming has a big heart, but now he has to think about preparing for the next technological upgrade.

And that's where the lathe really works.

Don't worry, this time you take a break before leaving. This king doesn't want to tire you out. Xiao Ming said.

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

Let's go, let's eat, this king asked Pao Ding to prepare your favorite smoked pig's trotters. Xiao Ming smiled.

When he mentioned this, Qian Dafu suddenly laughed, His Royal Highness, this old slave is just fine, it's worth eating this pig's trotters no matter how tired you are.

Xiao Ming laughed loudly when he heard the words, and Luluo also covered her mouth and smiled. After returning to Qingzhou, the girl gradually recovered.

Speaking of which, Xiao Ming also likes to eat smoked pork trotters, but Dayu Country does not have this dish. This is what he taught Pao Ding to make carefully. This Qian Dafu has become addicted to eating it for the first time. See you Drooling at the smoked pork trotters.
