In an empty school at Bowen Academy, Luo Xin and Yue Yun took their own people to sit down.

Xiao Ming was standing on the podium at this time. He looked at the people below and thought that he would probably live the same life as a teacher in the future.

For him, it is his advantage to popularize scientific knowledge as much as possible.

"This school will be the Naval Academy's school in the future. I will notify you to attend class in the future, so you will gather here." Xiao Ming said to Yue Yun and others.

"Yes, Your Highness." Yue Yun and others looked excited, and their answers were particularly loud. How could these fishermen who were fishing at sea think that they were qualified to teach in the school?

When they were young, they envied those who could go to private schools to study, because once they could study, it means that they would have hope of becoming high-ranking officials in the future, and not being able to study means that their destiny will only be the same as their ancestors and will only be fishermen for generations.

"Naval Academy? Your Highness, then should our artillery academy also have?" Luo Xin cheered.

Xiao Ming smiled and said, "Of course there is, the vacant room next door is the school of the Artillery Academy. After I hand over the method of aiming the artillery to you, you will be responsible for teaching the artillery."

"It's really there." Luo Xin laughed.

This Bowen Academy is a mysterious place to outsiders, because as an academy, there are guards here, and they are as tight as the military camp.

And unlike a small house in a private school, the Bowen Academy has a large area, there are many vacant schools in the college, and some are under construction. When they passed by a school just now, they saw Lu Tong talking about some strange knowledge in a school, and there were actually a group of scholars sitting below, which surprised him.

Xiao Ming nodded. For convenience, Xiao Ming planned to build Bowen Academy into a comprehensive academy, which is also for the convenience of class, otherwise it would be difficult for him to just run back and forth.

Moreover, although many scholars were admitted to the Blog Academy, based on the base of Qingzhou scholars, there were only more than a thousand people.

In addition, the number of technicians such as Lutong, Equipment Department, Mining and Military Workshops will be only more than 2,000 people in the future. In modern times, it is basically the size of a middle school.

So, now there are basically only people in one major.

After demarcating this school as the Naval Academy, Xiao Ming said: "Yue Yun, you said sailing is simple, so I ask you, how did you sail on the sea?"

"Of course you are walking along the place where you can see the land?" Yue Yun looked as if he was taken for granted, and he looked a little proud, thinking that Xiao Ming also didn't understand something.

Xiao Ming sneered.

This school is a brick-concrete structure, which is a modern tiled house. He specially ordered the blackboard to be left in front of the school.

Basically, this school is not much different from modern teachers. At the beginning, craftsmen didn’t understand what blackboard was, so Xiao Ming also came to guide craftsmen.

The blackboard in the school is actually very simple, it is just a glossy cement board, just apply black paint on the cement board.

At this time, in front of Xiao Ming there was chalk, and the chalk was limestone and gypsum.

In order to facilitate teaching in class, he deliberately made modern chalk with limestone and gypsum. After all, this is not a complicated process, and the cement was produced by the way.

Picking up the chalk, Xiao Ming drew a big oval on the blackboard of the school, and then outlined it one by one in the oval. Twenty minutes later, an accurate world map appeared in front of everyone.

"Your Highness, what is this? Is this a map? What is the map?" Luo Xin saw that this is a map, but he couldn't tell where this is.

"This is the world map, and this whole is called the earth. Now we live on the earth. Let me ask another question, do you think the saying "The sky is round and the place is right?"

Luo Xin grew up in the atmosphere of Confucian academics since childhood. He said, "Your Highness, you are joking. In the Confucian record, "The Great Dai Li. Zeng Zi Tianyuan", Shan Juli asked Zeng Zi: The sky is round and the place is really true. Zeng Zi said: The sky is round and the place is not covered by the four corners, which shows that the sky is round and the place is undoubtedly the place."

At this time, Yue Yun was silent. He had not received Confucian education. The people in the fishing village were illiterate and no one talked about it. He suddenly said, "Your Highness, the grass-roots people don't understand any classics, history, and collections, but every time we see the fishing boats back, we always see the sails first and then the hull. If the ground is located, how could this happen?"

Xiao Ming smiled and nodded. Luo Xin's thoughts were deeply rooted, but Yue Yun was prone to doubt because he did not study.

"The reason you see such a scene is because the place where we live is round." Xiao Ming gave the conclusion.

Luo Xin burst into laughter when he heard this, as if he heard a big joke, "Your Highness, I believe in you all the rest. Shu Luo Xin is rude. Your Highness can't talk nonsense about things passed down by his ancestors."

When he spoke this theory, Xiao Ming knew that he would encounter great resistance, and changing the ideas of an era was much more difficult than establishing an industrial system.

Therefore, he never thought of expanding the popularization of this kind of knowledge, but just spreading these advanced knowledge in the Blog Academy.

However, judging by Luo Xin's appearance, he basically understood what kind of experience he would have. Luo Xin was just a military officer. If he told those pedantic scholars, wouldn't they just be furious?

He sighed in his heart, and Xiao Ming thought that this popularization of scientific knowledge is a long way to go, and he must be patient and withstand the pressure.

He said, "Luo Xin, you know a lot. Then I ask you why the landing points of the shell are always a little different after you aim at a target with a cannon."

Speaking of this question, Luo Xin hesitated: "Your Highness, this is like a bow and arrow. The arrows shot will always fall, and the same is true for shells. If you train more, practice will make perfect."

"You know the reason but not the reason." Xiao Ming said with a smile.

Luo Xin scratched his head and said in confusion: "What else is there?"

Although Luo Xin had studied hard, in Xiao Ming's eyes, he only learned Chinese for ten years, so it is normal for descendants of ancient people to be unable to match the articles.

But Luo Xin is no different from math, physics and chemistry.

Of course, the aiming of this artillery also has the principle of parabola. Nowadays, artillery basically uses the aiming principle of three points and one line. There is no cannon with sight and sight.

But these sights were just for emergency response at that time, and the accuracy was not accurate. The reason why he called Luo Xin over here was to teach him to calculate the parabola and adjust the sight. In this way, the sight of the sights in the future was the landing point calculated by the parabola, and it was enough to hit it directly.
