For Yang Chengde's possible revenge, Yan Zheng is psychologically prepared.

As a person who had practiced dragon slaying, he didn't think that Yang Chengde could organize a team of men and horses to plow and sweep the caves on him.

Because he realized that when the situation was unfavorable, he would definitely turn into the wind and throw away the bottles and cans generously.

He believes that without 10,000 horses, Yang Chengde can't do this.

As for the 10,000 horses fighting across the sea, he did not think that they could hold on to the constant blows of guerrilla warfare and harassment warfare.

What's more, the biggest barrier on Dongfan Island is not the sword soldiers, but the miasma in the dense forest, if they don't cut down the dense forest and disperse the smoke miasma, what awaits them can only be malaria.

Therefore, as long as Yan Zheng has an aboriginal militia in his hands, he will always have a way out.

But what he can't tolerate is that this group of people really has the intention of entrenching for a long time.

Because it's like a knife, a knife that is slowly getting sharper, and if they measure the depth of the water, then they will be able to attack the salt harbor at dawn and evening.

This can be said to be fatal to Yan Zheng's development.

After thinking about this, Yan Zheng sighed silently, he used to watch the news, and he didn't understand why every country was so aggressive towards strategic places.

But now from the perspective of a ruler, he finds that if you don't hold some places in your hands, you will never be able to develop quickly with peace of mind.

………………

The next day, Yan Zheng came to the carpentry factory early in the morning.

He thought about it for half the night and made the decision to cast a cannon immediately, the truth was only within the range of the cannon.

Originally, he was going to play with the arquebus first, and the biggest threat was the natives anyway, but now he had to make the cannon.

It's just that if the cannon is put on the horse, it will affect the manufacture of agricultural machinery, which makes his peaceful farming cause have to be delayed again.

And it's really too expensive to make a cannon! A cannon is a few hundred pounds of steel, plus the expenditure of shells and gunpowder, it really burns money!

"According to this shape, make a batch of wooden molds." As soon as Yan Zheng arrived at the carpentry factory, he handed over the drawings.

The person in charge of the carpentry factory is called Astro Boy, and as soon as he heard the name, he knew that he was a lucky person who was given the name by Yan Zheng.

He was short in stature, his face was very clean, and he had a big back hair similar to Yan Zheng, he took the drawings and looked at them, and immediately asked, "How many of each type are made?"

"Let's build three first!" Yan Zheng sat down on the side and said, "Remember, the ratio of the double diameter, that is, the ratio of the caliber to the length of the body tube, must come according to my requirements!"

Astro Boy nodded, as someone who had been to school for a few months, he already knew Arabic numerals.

He asked people to pick a few pieces of wood of the right length and began to draw the parts to be worked on with a ruler.

The use of rulers is also a big step forward, and it is related to standardized production, because all the factories in Meocco use the same batch of rulers.

After the painting was finished, Astro Boy ran over and asked, "Miko, why is this body gradually getting thicker?"

"You don't have to worry about this, just make it!" Yan Zheng didn't want to explain why the spindle-shaped barrel was the most reasonable.

Astro Boy frowned and thought about it, and began processing.

Yang Fuyun also rushed to the carpentry factory at this time, this was his first day of work, and he found a place after going around and around.

After seeing Yan Zheng, he immediately said respectfully: "I've seen the king!"

Yan Zheng smiled and said, "Don't be late in the future!"

Yang Fuyun wiped his sweat: "Certainly, definitely!" The villain promises no next time. ”

"Then find a place to sit for a while, during this time, you will learn to speak new words first, and then let these masters teach you how to use these things!" Yan Zheng said.

Yang Fuyun nodded, wiping his sweat and standing aside.

Then he saw the scene that stunned him, a large piece of wood was fixed, spun rapidly under the human hand, and then quickly faded under the cutting of a knife.

Then there was a deep borehole, and a hole was drilled very quickly.

After measuring, you may feel that the size is wrong, and use another knife to increase the diameter.

A piece of wood seems to play with flowers under these kinds of machinery!

In fact, wood is easy to process, so for a long time, the earth-made machine tools of the carpentry factory were the first to be launched.

Half of the knives in it are high-carbon steel that has only recently been replaced, and they were basically made by the steel churning method in the past.

Soon, the cannon lugs were also brought out, and the entire wooden mold took on a spindle shape.

Astro Boy measured the amount and began to work on it with a carpentry planer.

This process made Yang Fuyun a little complacent, he felt that this indigenous was obviously inferior to him, but these people could use those tools.

Yan Zheng waited for about half a day, and this batch of wooden molds was made.

He praised all the employees of the wood factory with great satisfaction and said: "I hope you will continue to carry forward the dedication spirit of not being afraid of hardship and tiredness, and continue to contribute to our cause!"

Then he sent the wooden cannon mold to the first mold factory, and asked the first mold factory to make it urgently.

The cannon he chose to manufacture this time was a front-loading smoothbore gun, which can also be understood as a Napoleonic cannon.

There is also the rear-loading smoothbore gun, which is modeled after the Franc cannon.

It's just that the caliber he chose was 75mm, and the shells fired were estimated to weigh three catties.

This is also due to the lack of animal power, as well as the dense jungle on the island, which is not suitable for too heavy weapons.

………………

After coming out of the carpentry factory, Yan Zheng went to the teaching shed, which was already preparing to be expanded.

There were also many Ming children among the students, and after they shaved their heads, they all looked black and not much different from the natives.

It's just that these Ming children, when facing the natives around them, all showed a kind of uneasiness.

This is a kind of mind that children will inevitably have when they enter the unfamiliar, especially when they enter a place that is different from their previous living habits and customs.

For this reason, Yan Zheng specially selected Wang Jiang's to teach them a lesson, the reason is that they have been in contact with Wang Jiang's for a month, and their psychological resistance will be less.

"King!" When Wang Jiang saw Yan Zheng coming, he immediately saluted.

Yan Zheng asked directly, "Are all these children here?"

"It's all here, the youngest is five years old, the oldest is twelve!" Wang Jiang replied.

Yan Zheng nodded at her: "Good students teach them to read, just teach them according to my method, they now have textbooks, they should learn better!" If you don't understand, come and ask, don't pretend to understand, that's a mistake! ”

Wang Jiang said in fear: "Remember the teachings of the king!"

"Uh-huh, just remember it! I don't have a random check every once in a while, education is no trivial matter! ”

After saying that, Yan Zheng went to the other side and taught lessons to the indigenous children.

Now they have also been divided into classes, and those who learn faster have been promoted to a higher class.

The best of the higher students were sent to teach the new indigenous children.

The number of students currently enrolled has doubled.

And also launched a program to give names and surnames, all children who are enrolled in the school will be randomly selected from the fifty surnames as a surname, and then from the Chinese characters taught, one will be randomly selected, and two will be selected if there are duplicates.

This kind of education method of learning first and learning later is also similar to the literacy class in another time and space.

"Ladies and gentlemen, today we are going to talk about analytic geometry!" Facing the upgraded students, Yan Zheng said with a smile.

He immediately sent out the textbooks, all of which were printed on a wax paper printing press.

Wax paper is paper that has been treated with wax, which is selected from the fine paper sent by the Song family, and the ink is prepared with ramie seed oil.

The principle is also very simple, put wax paper on an iron plate, and then use an iron pen to carve out the content to be printed on the wax paper.

Where the pen is crossed, the ink slowly penetrates through, leaving a mark in the place where it is to be printed.

This is the simplest earthen printing press, the only drawback is that it is a bit expensive, and it cannot be printed on a large scale.

However, this thing is a teaching artifact that is highly praised by the majority of schools.

In his previous life, Yan Zheng had done a lot of test papers printed on wax paper.

When these test papers are made, it is easy to get ink on the sleeves and hands, and it often takes a long time for my mother to wash them off!
