Wang Chuan didn't know that he was going to boil a ferocious prehistoric giant eagle. Pen & Fun & Pavilion www.biquge.info the snow was later than planned, and he threw his arms and was ready to do more.

Sometimes you can't slack off in order to stay aggressive, and it's better to do everything you can see.

In the case of the current farmland water conservancy, Wang Chuan mobilized the tribesmen to get up early and dig ditches, and then he found that after there was more farmland, the amount of water might not be enough to rely on the irrigation of the creek alone, so he planned to build a large area of mountain pond or reservoir in the small col where the stream flowed out to the east of the village to store water.

Naturally, this work is better done before the snow falls. The farm will start in the spring of next year, and if you don't get it done now, you will have to wait another year to use it. If we can strive for a year earlier, how many fields can be planted and how much grain can be harvested?

The narrowest part of the col is less than 30 meters wide, and digging down the slopes on both sides to plug this narrow mouth can form a lake several hundred meters wide in the small valley. The project is not very difficult, the question is, how many people will be put into it before the snow falls?

"Let's talk about this thing tonight: Let's say there are still ten days of snow, and the plan for this levee we want to build is 20 meters wide below, 10 meters wide above, and 4 meters high, and the amount of earth we can carry per person is ...... So how many people should we put into it? ”

At night, the meeting hall was lit with torches tied with bamboo, and under the bright firelight, the centurions and ten-centurions of the tribes sat on the floor and listened to Wang Chuan talk about the practical problems that could only be learned in the fifth or sixth grade. Each of them had a small plank in his hand, but it was wider than that of the children, two feet in size, to cope with the clumsy hands of the fan.

Not surprisingly, these stupid students, who had only completed their amateur school for a year at most, made Wang Chuan gain a bunch of dog-like eyes looking at the stars.

Wang Chuan couldn't expect these people to understand this. But since I want to calculate such a problem, I should take it out and show it to everyone, so that everyone knows that there is such a thing, and it is good for them to see the use of mathematics. Even if no one understands in the end, it can be regarded as helping them gain insight.

Tribal schools have already opened. In Wang Chuan's plan, after the snowfall, everyone in the tribe would have to go to school. The time span is this winter. There was no expectation that the tribesmen would learn to write splendid articles, but Wang Chuan hoped that a few adults with outstanding intelligence would continue their studies and let them become teachers or join the management. At the same time, I hope that other people can learn some of the daily language brought by Wang Chuan, recognize a few words, or be able to do simple arithmetic.

Some of the language habits brought by Wang Chuan may be hindered in language communication if they are not studied uniformly. For example, in the direction, Wang Chuan brought the southeast, northwest, and the time was divided into morning and afternoon, and if there were still people in the tribe who didn't know what this meant, it might delay things. If they still don't have any idea of numbers, they may have the problem of killing five cows, but the tribe kills all the cows.

In addition, the management is the core of the tribe, and Wang Chuan has now changed the story under the campfire at night to a night school, which is specially designed for the management to give lectures to strengthen the cultural literacy and management ability of these people. As for what to talk about, Wang Chuan didn't list the corresponding courses, or he didn't have time to prepare for the class, basically he encountered something during the day and talked about these things at night.

Learning these things consciously is the main thing, Wang Chuan does not assess, but these centurions and centurions really have not made any progress at all, and it is estimated that Wang Chuan will not improve them again in the future.

Today, Wang Chuan finished reading the terrain and was preparing to build a dam, so he came up with this application problem of calculation engineering, but this topic obviously involves too many things. Wang Chuan listed all the things involved one by one and explained them in detail. The concept of volume, how to split the calculation, where to use multiplication and division, etc.

It took Wang Chuan almost an hour to finish talking about this. Then changed the title to two numbers and let them calculate by themselves, Wang Chuan lit the oil lamp and beckoned to Qi and the others behind the crowd, and entered the small office next to him.

The night school faced the management, but it was actually public, Ling, Dahei, Wolf Ting, a kind of clever child, as well as Yuzhu, Shang Xiang, Yiren and others all sat in the back and listened. Now Wang Chuan, the second grade of the school, is already teaching multiplication and division, and Ling, Da Hei and Wolf Ting can just give tutors to those stupid managers.

Wang Chuan prepared a pen and ink animal skin book in the small conference room to record the migration of the Yi people.

This is an important way for Wang Chuan to understand the outside world, so these records are very detailed. Wang Chuan basically recorded what they saw and heard day by day, and every time Wang Chuan had to recall seven or eight Yi people together, trying not to omit anything.

Through such records, Wang Chuan knew that the Yiren were not on the road all year round. They generally only walk on the road for about four months a year. He walked for two months in spring and autumn, and lived in the north and south for the other eight months.

In winter, it is cold in the north and there is a lack of food, so it is more appropriate to move to the south. In the summer, the south is very hot and the miasma is raging, so it is safer to return to the north.

Wang Chuan calculated the distance they migrated, ranging from 1,500 kilometers to 2,000 kilometers from north to south. The headquarters of the Yi people is in the north, and the place of residence to the south is not fixed.

Their migration route is not due north or south. Take the section near the River tribe as an example, they go from the northeast to the southwest. Walking all the way in this way, they will pass through a country of Ze in the north, and when they go to the south, they will also pass through a country of Ze. These two countries are rich in water and grass, which is conducive to the survival of migratory herds.

The most important thing is that after they pass through Zeguo in the south, they will enter a terrain similar to this side, and they will not encounter the problem of crossing the Taijiang River at all. Even the Yi people knew almost nothing about the Taijiang River.

This is also one of the places where Wang Chuan gained the most, he knew that the Taijiang River evolved one after another in later generations, and it became a waterway in later generations, but he didn't expect that the Taijiang River in this era could not even have a main waterway after passing through a swamp.

This also reminded Wang Chuan that the topographic map of the later generations in his impression may be completely different from the present, and he must not take risks with the experience of the later generations, otherwise he may not know how to die in the end.

The Yiren also told Wang Chuan that the tribes that lived on hunting beasts were not the only ones along the Taijiang River. And it seems that more and more people are joining the ranks. And it seems that the number of people who have migrated like this is also increasing. This made Wang Chuan have a relatively bold idea: if the tribe's agriculture develops to a certain scale, can it go to the Beast Hunt to plunder the population?

This idea is good, Wang Chuan wrote down this idea into a separate book, and plans to implement it in a few years.

The Yi people were very cooperative with Wang Chuan to tell what they had seen, first, this was an exchange with Wang Chuan, and secondly, a certain idea of Laiqi had a consensus among the Yi people: to coax this Elder Chuan back to his own tribe. Therefore, they talked in great detail about the situation in the north, lest Wang Chuan could not find the way.

Wang Chuan didn't know what Yiren was thinking, so he just tried to record it as much as possible. Sometimes when I think of any questions on the spot, I will ask them myself, and write down a separate article on these things.

For example: "Have you ever met a tiger rider on the road?" Tiger teeth tied to his face, the one with a scar here. ”
