As a mathematics that poisons the good youth of thousands of teenagers, it is indeed awesome to call arithmetic at this time. The major sciences of modern times not only began with geography, but also were inextricably linked to the flourishing of mathematics.

Speaking of which, the development of mathematics was also inseparable from geography in the first place.

There is no Guozijian in Chizhou, so there is only a higher education hall opened by Meng Zhuoyan and others. At the beginning, all the people who were trained here were official reserves, but with the opening of the county schools, Meng Zhuoyan and the others were busy with affairs and had no way to choose them one by one. As a result, the examination has become the criterion for selecting candidates.

According to Qin Cang's idea, all of them must be examined, and subjects such as Chinese language, scripture and righteousness, arithmetic, Ming etiquette, and geography have been studied one by one, and after passing the exam, they can be promoted to higher education and go to school in Chizhou. Of course, Qin Cang would not bear all of their expenses. Tuition fees are waived, and living expenses are also subsidized, but daily expenses are definitely not enough.

That's not all, when the one-year course of the higher school is over, they have to take the exam.

Those who have passed the examination of various political affairs, laws, rulings and other subjects in the higher education hall have 80 points, and can make up for various bureaus to do things. If you can't pass the exam, you have to pack your bags and go to your hometown or the countryside to become a magistrate. The magistrate also has to start from places like the three classes and six rooms in the county. If it is in Desheng County, Linhai County, and Xin'an County, where the system has long been complete, it is necessary to start from the townships and towns.

In general, Qin Cang had no intention of introducing Confucianism at all, and Jingyi not only tested Confucius and Mencius, but also took Lao Zhuang Yang Zhu. Fortunately, these courtiers who came to exchange said that 'the minister's mental state is very stable', otherwise this incident alone would be enough to shake the court and overturn the country.

The Jingyi Higher School that has completed the examination in the primary school will not be touched again. The only thing to consider is the official's style and writing. This has a special subject training, aiming at the eight-strand writing, one is one, and the second is two, and it must be appreciated by both the elegant and the vulgar, and both literature and science.

It's not an easy job, but want to be an official? Don't think that the official is for you.

Qin Cang, Meng Zhuoyan and others are now invigilating a final exam in the Higher Education Hall. They are the second batch, and the examination management is much stricter.

Watching everyone write and scratch their ears and cheeks, Qin Cang felt quite happy in his heart. I think it's the same with those teachers when they invigilate. It is difficult to pass the test by yourself, and you must let the students taste the hardships.

"Your Majesty, the four-pounder cannon is complete!" The craftsmen of the Great Iron Prison ran over to spread the word, so Qin Cang threw down Meng Zhuoyan and the others and ran away!

"Help me watch first, I'll take a look!"

The four-pounder cannon has always been Qin Cang's confidant. The two-pounder cannon is a bit too lightweight, and the four-pounder cannon can be used to suppress all kinds of enemies more effectively as soon as it appears! Especially Ottoman Turkey, which has now gone further and further on the path of gunpowder!

Of course, the four-pounder gun is not a panacea. Historically, flintlock pistols were first equipped in the hands of the Ottomans, and Qin Cang had to quickly follow up and make flintlock pistols. Now some of the arquebuses in the territory can't be self-produced!

Because the hydraulic drilling machine has been trial production, but steel! Where to get the steel for the drill holster? The steel made by the frying method is not as good as iron, which shows that the big iron supervisor in the territory still has a long way to go.

It is not wise to rely on the craftsmen themselves to make the barrel little by little, and the consumption is very large.

This is also the reason why the three mining teams that Qin Cang is looking forward to have arrived.

"The cannon weighs 1,800 pounds! The bullet weighs four pounds! The caliber is 2.5 inches (3.4 inches)! , the cannon is nine feet long (ten feet, three meters)! We've tested it, and the effective bombing shot is two miles away! It's no problem to hit six or seven miles farthest! ”

Chu Jing pointed to a slender cannon, but how to look at it and feel that it was a little shorter and said to Qin Cang.

"You...... Did you remove the long words from the cannon I wanted? Qin Cang asked speechlessly.

"Well...... We brought in an arithmetic. He did the math for a long time and said that the size of nine feet is very good. If the cannon body is added, more gunpowder will be used as the base. And the ....... we developed Isn't it good to have some granularity......"

Chu Jing scratched his scalp and explained to Qin Cang, but that face didn't look like a person who was good at lying.

"Tell the truth."

"We can't do it." Chu Jing clapped his hands and said, "The longer the cannon, the longer the cannon body, the more difficult it is to pour." How thick the cannon wall is, you need to think about it! We're working on it, but we're going to get the four-pounder out first. ”

"Let's see a few shots first." Qin Cang pointed to the target mound in the distance and said.

The target was a small hill, about a mile apart.

The artillerymen crouched next to the four-pounder gun, and after gesturing with their fingers, began to mobilize the elevation angle of the four-pounder gun. This is also the development of artillery. After the introduction of mathematics into artillery systems, elevation angles, parabolas, and so on appeared in the things that artillery needed to learn. However, most of the artillerymen relied on their own habits.

After aiming, the artillerymen began to load the gunpowder, put in the iron bullets, and then introduced the fire in the breech, and finally, with a command, the artillerymen lit the arquebus!

"Lie down!"

The four artillerymen rushed back three or four meters one after another, and a fish jumped to the ground!

"Boom !!"

There was a dull echo, and the whole field was filled with smoke and dust! The whizzing iron bullet smashed into the ...... Dozens of meters behind the hill, a huge earth pit told everyone about the power of this iron bullet!

Qin Cang patted his head, and it took a long time to feel that his hearing had recovered!

"Well done! Not bad! Very good! ....... Rewarding ......."

After a while, Meng Zhuoyan and the others were late.

Qin Cang, who didn't want to suffer alone, let the artillery fire another shot, who knew that Meng Zhuoyan and the others took out their wool and plugged their ears, making Qin Cang jump to his feet in anger!

"Anyway, you're doing a great job! You should contact Chen Jia more and see what his needs are. Is it a bigger cannon, or a more accurate cannon? Discuss it yourself, and then hand over a note to the cabinet. Qin Cang finally praised Chu Jing like this.

Leaving the big iron prison shooting range in the mining area, Qin Cang returned to the scene of the final examination of the Higher Education Hall.

Everyone is against cramming education, but you can't ignore the current state of society. In the face of a severe shortage of regular officials, there is a need for quick officials to maintain regional stability, especially in the newly established nine prefectures (including Hanmo, Binh Nam, and Linhai).

Qin Wendang also wrote a letter strongly asking a group of personnel to help him stabilize the place, because his rule was not very stable, and many Tatar tribes fought their own battles and ignored Qin Cang's orders.

With a headache, Qin Cang remembered in a trance, it seems that from next year, the Ming Dynasty exam will be divided into two systems, north and south? (Once Literature Network,)
