From Chief to Ball

After adding a "fifteen days" at the end of the second chapter, the second chapter leads to various agricultural terms in the third chapter, deepening the division of solar terms again, and introducing the concept of calendar at the same time.

As a continuation of the second article, the third article still inspires learners from the perspective of observing the world. I believe that those who have studied these articles will definitely observe the connection between morning glow, sunset glow and sunny rain.

The emergence of science starts from observation, and the law is found out from observation, and this law conforms to all observations. This descriptive scientific view is enough to support the unity of science and philosophy. Before there is a second person who can understand " Mathematical Principles of Natural Philosophy was enough before.

The fourth chapter is still a continuation of the third chapter, leading to the concept of southeast and northwest and the relationship between the sun and the southeast and northwest, and based on this, it is sublimated to the worship of light in the tribes of Dahe and the connection between flowers and flowers.

The rest are similar to these four articles, a total of eight articles, ridiculous and naive, a little less romantic of literati, a little more crude of lower class people, no subtle words, only scribbled and brief.

After Chen Jian finished writing, he counted and made sure that the simplest consonant and vowel words had been written in the first six chapters. The seventh chapter began to have the simplest pronunciation and pronunciation. The characters have phonetic notations in the seventh and eighth chapters.

It took half a year to complete these eight articles, and the last two of them took two months. They were mainly related to Qieyin spelling, to figure out the difference and connection between sounds and words, and a few more common ones. As the first batch of radicals, the radicals of 耳球 are used to let learners know the connection between radicals and real objects.

In addition to Chinese, there are three courses, among which simple addition and subtraction mathematics and Chinese are synchronized, which is a must for all students.The other two courses are labor and military training, mainly for the relatives and noble children of various clans who will be sent here to study.

Chinese and mathematics in the morning, labor and military training in the afternoon, and the examination system inherited from Xiacheng will also be strictly implemented: after half a year, all noble children are required to know all the consonants and consonants, and to be able to spell out unknown characters with Qieyin. Able to add and subtract within one hundred.

As for those free slaves, Chen Jian will not force them to study for the time being, because he can't afford to support so many full-time students, but he will give lectures at night, and all non-slaves can come to listen and take advantage of this spontaneous behavior After half a year, this kind of learning atmosphere will be stimulated with material rewards and status rewards. You can even get half a catty of corn every day by knowing fifty characters.

After three days of writing the templates for these textbooks, Chen Jian took the first volume of wooden slips and found young people who had studied in several schools in Xiacheng for a year or two, such as Ji Bai.

Ji Bo used pottery boards and steatite sticks when he was learning Chinese characters. He had never seen wooden slips written into a book.

"Do you recognize it?"

"I know."

"read."

"One to two three..."

After reading several articles in a row, Chen Jian asked again: "What do you mean by understanding?"

"Of course I understand."

"One to two or three miles, how did you get there?"

"A thousand steps is a mile."

"What's the relationship between that one mu and one mile?"

"One step wide and one mile long is one mu."

"How long is a step?"

Ji Bo was stunned for a moment, then scratched his head and suddenly realized, he took off the turban from his body and said, "Xia City has rules, soldiers' turbans are one step long and half a foot wide."

After unfolding it, he pointed to the long turban and said, "This is one step."

"Why is there a step?"

"Because when exchanging cloth and land, everyone's steps are different, so I choose the same step. It is the same two steps, and there is a big difference between children and adults."

"You just said rules, what are rules?"

"Gauge is a rule, which is used to draw a circle. Moment is a square, which is used to draw a square. Without rules, you can't draw a real square or circle."

After finishing speaking, he glanced at Chen Jian, and seeing him smile, he breathed a sigh of relief and said, "Ji Xia, are you testing me?"

"It's not about you, it's about myself. If you can understand, it means I have passed the exam. Go, hold this thing carefully, and ask Hongyu to find some women who manage numbers with her. There are wooden slips in the room, copy The first chapter has [-] volumes. Whoever copied the fastest and the most, let Red Fish write it down."

Chapter 78 Su Xia Limited Sovereignty System ([-])

"and many more!"

When Ji Bai turned to leave, he was stopped by Chen Jian again.

"After telling Red Fish about the wooden slip, you go and tell the soldiers who stay here to gather here, and I'll let them go out and find something."

As soon as Ji Bai heard that he was looking for something, he thought of Chen Jian's eccentric hobby, and said with a smile, "Looking for stones again? We followed you from Xiacheng along the river to Sucheng. You searched for stones all the way, and the boat was full. "

"Yes, all kinds of strange stones, you go and tell them. After you tell them, you don't need to use them. I will keep another twenty people...as a reward for staying in Onozawa for so long."

Ji Bai suppressed the excitement in his heart, carefully held the wooden slips and walked away quickly.

After a while, the remaining soldiers had already gathered here. Chen Jian picked out a dozen of the best people who had been trained on weekdays and asked them to go back first. I want to find all kinds of weird stones, and take out some of the stones I picked up on the boat and distribute them, so that they can find them according to the map.

"What I want personally has nothing to do with public property. If you find a strange stone, you will be rewarded. If you can find the stone I mentioned, you will be rewarded with thirty slaves, five horses, and a hundred acres of land near Xiaqu. Look at who you are Good luck. You know how much my property is, and you will never fail to give it up, and you don’t need the approval of Sihu Ji. This is mine, not public property, and you will give it if you find it.”

The soldiers knew very well that it was difficult to get rewards beyond the rules from the secretary. They all giggled and kept in mind the strange stones and strange terrains that Chen Jian said, and took the various ores that Chen Jian had prepared. When you get it, store it in groups of three or five people.

"Jixia, ocher is found on the mountain. I've seen quite a few. We used it to paint our faces before, but I haven't seen the ocher you mentioned. You said that there must be iron on the mountain, so don't tell me? Iron and ochre are like emerald stone and copper? If we really find that kind of stone, we can smelt iron like copper? Besides, there is ochre on this mountain, why did you go to see it and then left?"

Chen Jian shook his head and said: "There is too little ochre on the mountain, so it is useless. But you guessed it, if you can find the ochre I mentioned, we can really make iron. Go find it and come back within fifteen days. Whether we find it or not, we still have important things to do."

"It's best for you to search along the tributaries of the river, spread out, and don't gather together. In addition to the kinds of stones I mentioned, you should also look carefully for the emerald stones and lead stones you have seen in Tongshan. .Besides, I also need to write down the mountains and rivers you pass, and the grass and trees you have never seen before, and I will return them, as long as I think they are useful, I will reward them one by one.”

After thinking about it for a long time, there was nothing to tell them. This group of three or five people, carrying bows, arrows, copper spears, and Tao Lei gunpowder on their backs, was not afraid even when they encountered bears, tigers, and tigers.

The mines are not necessarily hidden under the deep mountains. The mines I have seen in previous lives are all under the deep mountains, because those that are easy to mine in the open air have been excavated by the ancestors. In later generations, the outcroppings were mined.

Looking for copper with malachite and iron with ochre, this is the most common way to find ore a long time ago. It is said in "Guanzi" that if there is ochre on the mountain, there must be iron at the bottom.This kind of open-pit ore is called an outcrop mine, because the ore will be exposed due to precipitation and is very conspicuous. It was called a ore seedling in the past and ancient times.

If you can find the best near here, if you can't find it, you can only pray to find it upstream, and transport the selected ore here by water.

It's not that he doesn't understand that this will increase the cost, but legally, he can only build a city near Onozawa along the river, and he doesn't want to expose the workshop to other cities where he can attack at will.

The Meteor tribe uses natural nickel-iron alloy, which cannot be replicated and cannot be mass-produced. Although Chen Jian has not yet figured out how those people reached such a high temperature, he does not want to find out. The technology of mass production meant nothing to him.

Once you find iron ore, you can use low-temperature forging and carbon reduction to make simple sponge iron in the early stage. It can't be used to make swords, but it is very suitable as a farm tool. Xiacheng has been smelting copper for several years, and the kiln closure and heating technology have been mastered. Yes, the blower leather is more perfect than before.

There are neither copper mines nor formed iron mines on the cape island, only some ochre, not too much, but even these ochres Chen Jian is not going to waste.

After sending the soldiers out, he found Ge Ze and the others and asked them to call together the people who were making the bricks.

"Closed today."

"Stop work?"

"Correct."

"Then... is there still corn in the shutdown? We don't want to stop work, but still want to do it."

"That doesn't work either. You are not slaves, you are just selling your strength to me. I don't want your strength anymore, why should I give you corn? This is a mutual voluntary matter. If you want to do it, I don't want it."

Ze smiled wryly, but he knew that although Chen Jian said so, it was absolutely impossible to let them rest in vain. As expected, Chen Jian said again: "It is already early autumn, have you ever seen some book leaves with pimples? tumor?"

He nodded and said: "I have seen it, and I have seen a lot. Those trees should be sick."
