"I want to know, I want to know. Pen ~ fun ~ pavilion www.biquge.info but for the entire tribe, these playthings can't be exchanged for those four days. It was a day that the clansmen and their ancestors had observed for a long time to know. ”

Shu Jiu bit his finger hard, and in the severe pain, he finally took his eyes off the clay plates, trying not to think about the magic inside.

Numbers and shapes, to her, are like a fish to those cats near the tribal granary, and she is unwilling to give up like this, but she will not give up the interests of the tribe for her own liking.

She was first and foremost a priest of the tribe, and then a number nine who loved numbers and shapes.

In the era of the use of copper and stone, there was mathematics, and the level was not too low. The Mayans couldn't even play with bronze, which could still be astronomical; It is impossible for Dayu to control the water without measuring the height of the mountains and the width of the river, and to dredge it with his eyes closed; The standard square city wall and the height difference of the ancient city site of Pingliangtai and the pottery water supply and drainage system of the height difference are unlikely to be coincidents that do not understand mathematics.

Therefore, Jian Chen was not surprised that the other party would be interested in these strange numbers, after all, the other tribe knew how to observe the sun and shadow to calculate the seasons and divide the seasons.

Seeing her refusal, Jian Chen said: "This is not just a plaything, you can stand on the edge of the field and use a wooden stick to measure the size of the land, how wide the river is, and how high the river is." ”

The eyes of the number nine lit up, if this is the case, it is indeed worth exchanging.

After the tribes migrated here, the newly burned land had to be distributed to each family, not a small family, but a large family of more than a dozen or twenty people.

In the past, the way of measurement was too tiring, and it took her a few months to take people to test with a rope little by little, and if it was really possible, it was indeed an acceptable way of exchange.

It's just that she is a little puzzled, it is said that Chen Jian should be in a hurry to talk about soybean seeds with him now, why did he suddenly think of exchanging these?

I couldn't understand it, but when Jian Chen began to use numbers and shapes to compare those simple tricks, Shu Jiu couldn't help but listen intently, and no longer thought about the things that she didn't think was right.

During the explanation, Jian Chen found that the foundation of the number nine is quite good, she can easily calculate the addition and subtraction and multiplication and division of small numbers, and she will use a strange calculation chip for slightly larger numbers, which is about a necessary skill for a priest in charge of divination and calendar.

He didn't talk about anything too difficult, just some tricks and algorithms from later elementary schools and a little bit of similar triangles, which took three days.

Shujiu suddenly found that Chen Jian knew far more things than himself, and even some numbers larger than a thousand could be easily calculated, and even just by drawing a few strange runes with charcoal, he could calculate them, but he needed to use the help of a calculation chip.

Originally, she really believed what Jian Chen said, her own advantage is in the number, and the other party's advantage is in the form, but with the explanation of the past two days, she suddenly found that she was afraid that Chen Jian was also stronger than herself in numbers, but how could he not see through the things contained in the nine-number chart?

These doubts only existed for a moment, and then she was attracted by other things that Jian Chen said, many of which were questions that she had thought about before, but did not find the answer, Chen Jian's words were like lightning in the night, suddenly illuminating everything, so that those previously incomprehensible questions were answered.

The initial question was very simple, and there seemed to be no connection, but on the third day, she suddenly realized that the things she had said a few days ago could be connected, and she said "what if...... Then there must be something like "......" that pushes two otherwise unrelated numbers into another problem.

The number nine pondered for longer and longer, and the excitement became more and more obvious after each contemplation, Chen Jian quietly observed her expression, and finally stopped abruptly when he began to talk about similar triangles and the Pythagorean theorem to calculate the land area and the width of the river.

Yu Qian'er pushed the door in, leaned in Chen Jian's ear and whispered a few words, and Chen Jian's face became solemn.

Shujiu is like an addicted person who suddenly cuts off the source of addiction, and anxiously points to a few clay plate squares and says, "What's going on?" Why didn't you say it? ”

"I'm leaving, the tribe has something I need to take care of."

Shu Jiu didn't stop it, but recalled what Chen Jian said before, immersed in it, and it wasn't until lunch that she noticed something strange, why hasn't Jian Chen come back yet?

When he left the hall, he found that a large number of people had gathered on the docks of the city, carrying bags of twine and various jars to the ship, and one of them accidentally broke the jars and threw out the white salt inside, which attracted the scolding of one of the leaders.

Counting them carefully, there were at least fifty bark boats, piled with all sorts of cargo, and even two pairs of wheels.

She felt a little uneasy in her heart, and hurriedly found her clan to ask, for these days she had been pondering the numbers and shapes in the hall during the day, hardly going out, and even thinking about those questions at night, and not noticing what was happening in the city.

The people who followed her only said that in the morning it seemed that a boat had returned from the south bank of the Caohe River, and today they began to get busy, and a few people dressed in strange clothes and speaking strange things lived in the houses in the city, but they did not understand.

"Other tribes?"

A sense of foreboding suddenly welled up in the mind of Number Nine.

She and her people had migrated from the lower reaches of the river, and had seen many tribes along the way, including those who carried the old man to the mountains to fend for themselves, and those who shared a few women between her brother and brother, and of course she would not think that there were only two tribes in the whole world.

According to the instructions of the clansmen, she quietly looked into a room in the distance, and after waiting for a long time, she finally saw a woman come out of it.

Just by glancing, she felt that she had guessed correctly, there were really other tribes, because that woman's dress was very strange, and it was impossible for her to deceive herself at random.

The woman was not very old, her hair was not combed, but cut very short, draped over her shoulders, and she wore a hat like a boat on her head, made of linen, and tilted diagonally to one side, she had never seen such hair and a hat before.

He wears a non-collared blouse with a row of screw buttons, and the sleeves of the shirt are also very narrow, tightly wrapped around the body, and there is a collar near the neck.

Underneath is a pair of leather pants, I don't know if they were sewn with thread or glued with feet, very thin and stretched on the legs. Under the knee are very high shoes, also leather, the upper covers the calf all the way to the knee, and the heel of the shoe is decorated with two bronze thorns, which are about the time to make the mount sting and run fast when riding a horned deer or ox.

If Jian Chen were to describe it, the woman wore a boat-shaped combat cap, a simple linen shirt with leather pants and an armed belt, and long riding boots with boot thorns...... The reason why he knows so clearly is because he planned it single-handedly, and it took him and his clan four days to rush out, and the role was played by Red Fish.

With his lack of imagination, it is impossible to come up with a completely different style of clothing, so he can only make one from the memory of his previous life according to the shape of the woolly bear female soldier, and by the way, he can enrich his nightlife and add some mood in the future.

Clothes and hair, the best way to see from different tribes, especially this kind of seemingly weird, but a closer look is not awkward, on the contrary, there is a sense of heroism, uniforms, not only to seduce men, women will also feel very good, number nine is more sure that there are other tribes.

After a few glances, the woman was talking to the people in the room, in a language she had never heard before, but she spoke fluently, and could faintly hear a few repeated words, not nonsense.

Hurriedly found the clansmen, I was very uneasy, the exchange of my own tribe must be completed, now only my own tribe can be exchanged, once there are other tribes, then it is impossible to exchange so many things for corn and corn, especially the woman's dress and demeanor, will not be a barbaric tribe, the barbarian tribe is not capable of making such clothes, although it is strange.

After thinking for a moment, she came up with a bold idea.

"Kill those guys."

The clansmen were startled and asked, "We will die, but we can't beat them." This will lead to a war between the Jian clan and us, and Eyue didn't say that he would fight. ”

"No, it won't. Kill those people, Ken can only exchange with us, and he will have a grudge against that tribe, after all, if a person dies here, he can only be tied to us. As long as you don't hurt the healthy people. He is very cunning, and if he kills those few people, not only will he not kill us, but he will also make an exchange with us, and even make an oath. ”

The clansmen were a little puzzled, but they knew that the words of counting nine were rarely wrong, so a few people felt out the sharp stone dagger bone spurs and left the hall, but soon came back with a bitter face.

"No, there are more than forty people guarding there, all of them are bronze soldiers. They had already taken precautions, and the girl named Yu Qian'er also went to that room. ”

Shu Jiu clenched his fists, gritted his teeth and chattered, and was silent for a moment, so he had to push open the door and go out.

found the person in charge of communication, found Jian Chen, and asked, "What are you doing here?" ”

Jian Chen apologized: "I want to go to the south bank of the Cao River, it may take more than twenty days to come back, the affairs of the tribe are in charge of my sister for the time being, you can talk to her." ”

As he spoke, he asked the people to load some salt shakers and baskets onto the boat, and there were some white powders in them that they had never seen before, and someone accidentally spilled a basket of white powder into a puddle by the river, and the water in the puddle immediately boiled.

"Not food, not pottery, but salt and this weird white powder...... That tribe has no shortage of food, no shortage of pottery, and he wants to change seeds! ”

Thinking of this, she tried her best to calm down her somewhat panicked mood and smiled: "More than twenty days? It's too late to come back in 20 days to plant beans, today is the thirteenth day after the beginning of summer, and there are still 20 days at most, and if you don't plant it, it won't be ripe. ”

The clansmen in charge of communication could only transliterate the word Lixia, and Jian Chen didn't understand what it meant, but he could guess that it was a day in the calendar.

He spread his hands and said: "It's not a bean, it's a kind of tuber, which can be planted, and that tribe eats this thing, but the taste is not very good, and it is a little bitter." That can't be helped, we won't change the wheel making, and we will be able to grow wheat and peas again in a few months. ”

After a few nonsense words, what he said made Shujiu believe it even more.

Turning around, he pretended to ask the clansman: "Where is Yu Qian'er?" Let her accompany the number nine. ”
