Everything is orderly and dazzling for those who step into the city for the first time, but there are many people but not too chaotic, walking on both sides of the road. The rider said it was the rule.

The city was square, measured by a ruler. The square in the center is round, drawn in a circle with a rope straightened and tied to the center. The rider said it was the rule, too.

These people think that the rules are good, even though they are hearing the word for the first time and have no idea how it came about.

But soon they saw the other side of the rules.

Not far away, there were five adult men crying, and a bearded adult man was crying, which made these people feel a little scary.

Five men had a pair of rabbit ears stuck in their hair tied up, and one had a cloth wrapped around his arm, oozing blood, apparently wounded.

The five of them wept and walked out of the city. The rabbit ears were ugly, and no man wanted to be a timid rabbit, but the five men didn't take the rabbit ears off.

The group looked at it for a while and asked the rider in front of them, "Aren't these people from your clan?" ”

The rider sighed and pointed to the man with the wound on his arm: "That's my brother, a mother's brother." ”

"Why are they crying?"

"They fled the last time they fought, and they were to take their rabbit ears with them until they proved that they were not timid rabbits again. After that, they could no longer live in the city, but they had to move out of the city to work as slaves and take care of the flock, and when the flock was as numerous as the people, they would return. ”

A few people felt a little cold all over their bodies, and they couldn't beat them and escape, which was normal, why should they be forced to move away?

He ...... He's your brother, aren't you worried? ”

"He's my brother. But I still have my brother, my sister, my sister and my mother, and if they all run away in the fight, my sister and mother will be killed. ”

"Aren't you from the same family as Ken?"

"Yes, my mom and his mom are sisters."

"Then why didn't your brother beg him?"

"It's a rule, it's useless to ask anyone."

"What the hell are rules?" The group was a little confused.

The rider was speechless for a moment, he knew that it was a rule not to run away in battle, and that it was a rule not to pile firewood on the road in the city...... But what are the rules themselves? He didn't know.

Seeing Yu Qian'er not far away, he shouted, "Yu Qian'er, come here." ”

"What for?"

"What are rules?"

Yu Qian'er said in her heart Fortunately, you asked me today, my brother only told me yesterday, if you asked a few days earlier, I wouldn't know.

But now that he knew, of course, he had to put on a look of knowing it for a long time, and took out the ruler and the ruler from the room.

On the ground, he drew an angular rectangle with a ruler, and a circle like the sun with a ruler.

"That's the rule. If you want to draw a circle, you have to use a ruler; If you want to draw a square, you have to use a ruler. You can't draw empty-handed. ”

The men looked at the near-perfect geometry on the ground, picked up a branch and tried to draw it without a ruler, but the drawing was crooked and not at all.

Yu Qian'er recalled what Chen Jian said a few days ago, and said in a learned manner: "The city is square and square; The square is round, it is a rule. Therefore all the people in the city must be square and round, and they must obey the rules. ”

"What happens if you don't follow the rules?"

Yu Qian'er pointed to the men who were crying and walked out, "That's it." If you want to be in the city, you must obey the rules; If you don't want to follow the rules, it's just outside the city, and no one cares. ”

Several people learned a new word, and this new word also made them make a different choice.

The beauty of the city and the restraint of the rules have their own weight in the balance of the heart. There are those who like it, and there are naturally those who hate it.

…………

On the circular square, Chen Jian and several leaders received the group of people who came to thank them, and took them to worship their ancestors together.

Even though the food of the tribe was not sufficient, Jian Chen still entertained them with the best food.

Pastries made with maple deer milk and hazelnut almonds, the few leftover liquors, sashimi......

Before leaving, I gave them some clay pots as a return gift, which was quite a lot, and it would not be possible to exchange so many normally.

There are several tribes who want to move here, and Chen Jian said very clearly that if they move here, they must first be wild people, and the tribesmen will teach them to build houses and grow wheat, but they must pay for grain and serve; If they don't move, they will be free, and he won't let them pay tribute to anything, but they must come every year when they worship their ancestors.

In addition, if their tribe does not have much food, they can come here to plow the land, and he will provide them with food, and give them some grain, clay pots, maple sugar, salt, and the like in the autumn according to the amount of plowed land.

Everything was up to them to choose, and even if a tribe wanted to move in directly, he wouldn't agree to it.

The seeds of spring have not yet landed, and if you want to plant them, you have to wait until autumn, which is troublesome, and there are still a lot of things to deal with in the clan, and they are so busy that they don't have the heart to think about the affairs of these tribes.

In the seven or eight days since he came back from the battle, Jian Chen has not been idle.

After returning, it took a day to bury the ashes of the dead in battle, hold a ceremony, and by the way, deal with the soldiers who escaped from the battle, and make an example of the chickens and monkeys.

Then the spoils were to be divided, and the male and female slaves were divided according to the number of troops sent, and the rest of the tribes could not control it for the time being, so they were all handed over to him, and they were not accepted back until the wheat was harvested.

There were hundreds of people all at once, and eating was a problem. Even if you are a slave, you can't just work without eating.

Fortunately, spring has arrived, the population is not large, and the gifts of nature will not starve the tribesmen to death.

The people were taught to milk cows, and the ewes and doe could be milked until autumn if they had enough food, as long as they were uninterrupted, and within a few days they would no longer produce milk.

Fern roots, leaves, elm money, frogs, fish, newly awakened snakes...... Whatever you can catch and eat is eaten, the good ones are given to the people, and the bad ones are boiled together for the slaves.

Chen Jian and all his clansmen spent a day digging thousands of tree holes in the maple forest on the south bank of the Cao River, inserting pottery shards, and placing various clay pots underneath.

Spring is the time to harvest maple and birch sugar, and the nutrients prepared for spring germination are now collected in the heart of the tree and turned into sugar.

Leaving aside issues such as sustainability, there are so many tree holes dug that a tree will die in less than two years, but there is enough syrup to take at one time.

Most of the people were boiling maple sugar, a few lit copper stoves, and some nimble women squatted in the room to make wax patterns, which Jian Chen told them to finish in ten days.

There are still two months to go before the winter wheat harvest, and after harvesting the winter wheat either the land is left empty and the autumn is replanted; Or you have to plant beans, which can mature in three or four months. Wheat cannot be harvested until winter arrives.

The newly cultivated land and the burned land could be used to grow crops such as spring wheat, millet, and sorghum, but there were no seeds.

In the climate of two years and three croppings, the maximum use of land should be: the first year of autumn wheat planting, the second year of wheat harvesting and beans, after the harvest of beans, the wheat planting is late, the winter is fallow, the spring of the third year is planted millet, and the third year of autumn continues to plant wheat cycle.

But now the tribe only has peas and wheat, which can't last three crops in two years, so Chen Jian hopes to start a trade with the moth tribe in exchange for some seeds.

The food of that tribe is very sufficient, and it can be seen from the time when he traded with female slaves, and the other party did not hesitate at all, so it can be seen that the food is sufficient, otherwise he would not want these female slaves.

There is still more than half a month before the best time for spring planting, and even if you can't catch up with spring planting, you need to change back some seeds suitable for summer planting. After harvesting the wheat, it is almost necessary to plant beans and the like at the same time, otherwise it will not be ripe before the frost, and the hard work will be in vain.

There are many things that Jian Chen wants to exchange: seeds, cows, the technology of plowing pigs and geldings, silkworm moths, and those things that he doesn't know are worth exchanging.

He has a certain technical advantage on his side, and he can change anything except for bronze smelting technology.

Even if the other party wants the white horned deer under his crotch, as long as he gives the seed, he will not hesitate to change it.

Considering that the other party did not trust him, and even had a little hostility, Chen Jian decided to send an envoy first.

A few days later, the gift was ready.

Chen Jian made a brush from the hair on the weasel's tail that he had brought back, and scraped the bottom ash of the black pot, pine resin putty and fish maw glue scraped from under the clay pot for cooking, and boiled a simple can of ink.

He scratched his ears and cheeks and drew a picture on the silk silk, to the effect that he wanted to build a small city on the border between the two tribes, where the two sides could exchange goods, not for the purpose of war.

He had already thought of the name of the city, it was called Shang, which was a word that was meaningless to the clansmen, but with the power of this victory, the clansmen would not object to such a trivial matter, and he wanted to have a familiar and customary name.

At the end of the letter, a cow is drawn, and one man cuts off two circles, indicating that he is dissatisfied with what he has done for him.

Finally, a stamp was made of pine resin, which was in the shape of an ear of wheat, and after printing, it was dried, and the silk silk was placed in a birch bark rolled out of a leather bucket to prevent it from getting wet from the rain.

Thirteen riders took the jade jue given to Chen Jian by Eyue as a token, and set off along the river bank with the prepared gifts.

There are not many gifts, but they are all very characterful.

A bronze moth that has been melted by the lost wax method and is ugly, but the shape can be seen more or less by squinting the eyes.

A silkworm made of bronze, this one is relatively simple, and the shape is more similar, making up a pair.

There is also a fist-sized silkworm cocoon-shaped false amber made of pine resin, which is wrapped in a few leaves.

In addition, there are two polished bronze mirrors, two bone flutes, a pair of pottery xun, two gourd wine, two gourd fruit vinegar, two packets of maple deer milk almond hazelnut candy, an iron kitchen knife, a rectangular ruler, two packets of white salt, two pieces of soap, two beeswax candles, a jar of wheat grains, a jar of peas, and a scale.

Now that the tribe has entered civilization, the leader will understand what rectangular rulers and scales mean.
