At this time, a tribe member accidentally broke the saw due to an anxious heart.

He sat on the ground with a saw broken into two pieces, and slashed his feet and cried loudly.

The people of the tribe were full of anger at him and scolded him one after another.

The saw broke, just make another one. Although it’s a pity, it’s not as good as crying!

Ye Qing asked him why he cried, and he said while crying:

"I'm guilty! I'm guilty! I'm guilty..."

"This is a magic weapon that can only be used by the gods. It is a magic weapon given to the tribe by the gods! Now that I have been ruined, I am sorry to the tribe, I am sorry to the ancestors, I am sorry to the tribe members... I am a sinner!"

The tribe members actually value saw so much!

Ye Qing had no choice but to persuade him:

"This is made by me, not by gods. If you punish me, I will punish you, not gods. Don't cry... I forgive you!"

"Really?"

"real!"

"Hehehe..."

He burst into tears and laughed.

Ye Qing: “…”

It's so simple and cute!

The saw is the first time for all tribesmen to use, and there is no experience at all, so it is normal to accidentally break the tool.

When it comes to the importance of tools, the tribe members actually have to cherish and love many times more than Ye Qing himself.

For tribes who lack production tools, each of the tools invented by Ye Qing is a magical tool, which can bring great benefits to the tribe and great help to the tribe's survival.

It is related to survival, and no matter how much you pay attention to it!

...

The tribe members, including Ye Qing, are all novice. Under Ye Qing's guidance, what they make can only be said to be barely available.

However, now is not the time to pursue quality.

Skills require a lot of practice to improve.

He tried his best to make each tribe focused on a single job, so that it could improve the proficiency of the tribe's single skill as soon as possible, which would be of some help to improve the quality of the finished product.

Lulu, a guy with an extraordinary understanding, was drawn out by Ye Qing to dig out the mortise and tenon.

After making a few mortise and tenons, he felt that the mortise and tenons he made became more and more standard, more precise, and faster.

The tribe has long invented the mortise and tenon structure.

In some places, mortise and tenon structures have been used in the thatched huts where the tribes live.

However, in the past, due to the lack of tools, the processing of mortise and tenon structures was too difficult. If you can do it, you should try not to use mortise and tenon.

The mortise and tenon needed for plowing, raking, and the mortise and tenon structures are all the simplest mortise and tenon structures, and they are all stupid and silly styles.

Therefore, it took four days for Ye Qing to bring these primitive man "carpenters" to make all the plows and rakes needed.

After the land is cleaned up, the next step is to build ridges, dig ditches, and block rivers and store water.

Before doing this, there is one more thing to do.

That is to measure the land acres.

These new fields will be distributed to each household in the future. The long-term eating of big pots has been proven to be unworkable by history.

Distribution involves the issue of fairness.

Don’t worry about lack of weight but not unevenness.

This is true for human nature, and it is an immoral issue.

Ye Qing planned to divide the size of each field into one acre.

For the tribe, it doesn’t matter how they divide it. Ye Qing is for the convenience of himself.

With the reference unit of length, measuring the size of a mu is very simple.

So, how many square meters was acre in later generations?

It is 666.6666666666666…

This number is too 6!

Although this number is neat, why isn't it an integer?

It is actually inconvenient to bring so many decimal points.

Isn’t this artificial dyscalculus?

Is it artificially difficult to distribute?

Why?

Is it the people in power who bully the people but do not study, which makes it easier to fool the people and make trouble?

Of course not!

The actual situation is just the opposite. The size setting of the ancient acres was completely set for the convenience of the people, and it was very humane and very friendly.

So why does this cause this situation today?

The reason is that the units are different!

In ancient times, when measuring acres of land, the unit of length was not rice, but zhang, while one acre was 60 square abbot.

60, this is an integer.

This integer is also a very particular integer.

The number 60 is the most convenient for the people.

First of all, the 60 square abbot's field is very suitable for the size. The grain output of such a large field can ensure the basic survival needs of a people... not to starve to death.

If you pay half of the grain with a yield of about 300 kilograms per mu, you can still starve to death if you save food by one person in a year.

It’s not that you can’t starve to death, it’s that you won’t starve!

Why do these two words often talk about them together? One Ding and one Ao, the people will not rebel if they cannot starve to death!

The common people will also know that to survive, at least a few acres of land should be at least a few acres of land if they have a family.

It’s just a pity that the people are too simple and cannot even stick to this bottom line, which has let down the painstaking efforts of the sages...

Secondly, the number 60 can be divided by 2, 3, 4, and 5, making it easier to divide.

Again, the number 60 has a special significance to the ancients. One year of Jiazi and 60 years represents a cycle of reincarnation.

Living to the age of 60, you will be able to die!

If you are over 60 years old, you will live more and make a fortune!

Therefore, any tradition that can be passed down for a long time has its own truth and conforms to some law.

Ye Qing thought that he had to abide by two principles by dividing the size of acres himself: one is convenient for division, and the other is that the grain planted is enough for one person to eat enough and not be hungry.

As a time traveler, you must make more progress than the ancients. Then the goal cannot be limited to "not starving to death", but rather "not starving"!

Now, the benchmark unit I have built is meter.

In this way, the Mi unit is not easy to do.

If divided according to the size of modern acres, 666.666 is not easy to divide.

It is set to be 600 square meters as one acre, which is a bit small!

The rice yield is low now. The fields of 600 square meters are about 180 kilograms of rice per season, so one person can't eat enough.

Then, double it and set 1,200 square meters to one acre!

Um?!

According to the current yield, the yield per mu will reach 360 kilograms of rice per quarter, one kilogram a day, and you can eat enough and have surplus. In another season, the year is not too long. Even if the flood floods for one season, the one that needs to be handed over will not be hungry. It is great.

Moreover, the side length of the paddy field is divided into 30 meters by 40 meters, and the diagonal line of the field is 50 meters, with three strands, four strings and five strings, and everyone in the tribe understands the Pythagorean theorem.

It's amazing!

This is conducive to promoting mathematics and improving the mathematical literacy of the people.

Ye Qing did not have profound sociological knowledge, but he would never be wrong in doing things with the principle of people-oriented.

He only needs to remember the four words of clothing, food, housing and travel, and the road will not be deviant.

He tied a large amount of hemp rope with red and green marks. The red marks were 30 meters long and the green marks were 40 meters away.

The ridge of the field is 20 cm wide and 50 cm deep, and the ridge is 1 meter wide and 50 cm deep. Two fields are arranged side by side to form a ditch, and the ditches in the field are oriented north and south.

On the northern section with a slightly higher terrain, dig an artificial river with an east-west width of ten meters to store water.
