During the Spring and Autumn Period and the Warring States Period, there were various weights and measures in various countries.

The way to determine this is very strange, such as the length, which may be the distance of a yard with a certain monarch's finger, and then set according to that length.

In the Shang Dynasty reform, there was a very core law that implemented unified weights and measures, abolished all weights and measures in the original Qin state, reformulated them by the government, and issued reference samples of standards to various places.

This is also why Lao Qin can engage in the earliest standardized production, and Qin's arrow clusters and bows and crossbows can be interchangeable no matter where they are produced.

Therefore, Qin Shi Huang unified weights and measures, not that this idea suddenly came to mind, but with the unification of the six countries by the Qin state, the Qin law spread to the six countries, and then the original weights and measures of the six countries were abolished and unified weights and measures were adopted.

Thousands of years later, in order to facilitate trade and collect taxes, weights and measures were changed from dynasty to dynasty, and gradually became the symbol of orthodox dynasties, but they were not decimal system.

Yan Zheng wants to unify weights and measures, which is naturally to spread the management system further in the future.

It is only under the existing conditions that it is not possible for him to determine the standard units of length, volume, and weight.

The length of the first 1 meter is determined by the time it takes exactly 2 seconds for a pendulum with a length of 91.2 cm to swing back and forth.

But Yan Zheng couldn't measure the time, and he didn't have a ruler to tell him how long 1cm was.

In desperation, he could only learn from those monarchs in the Spring and Autumn Period, using a certain length of his body as a standard.

He thought about it, the little brother was too long and not suitable, and it would be too casual to use his fingers to draw a yard.

In the end, he decided to use his height as a reference, and he returned to the age of twelve after his physical crossing, and he remembered that when he was twelve years old, he was about 150.

Therefore, he directly delineates according to the integer of 150, and he believes that if there are more than 100 centimeters to spread the error, then the error with the modern standard length can be reduced to a very low level.

He first asked his people to get a hemp rope, and after straightening and measuring his height, he got a rope of 150.

Then through the Pythagorean theorem, an angle of 60 degrees is determined.

With this angle, it was eventually possible to make the rope equal in three parts, so that the length of one meter was determined.

With the unit of length, the volume can be determined, and once the volume is determined, the weight can be determined using a liter of water equal to a kilogram.

After ten days of tossing like this, Yan Zheng got the first batch of weights and measures tools.

One meter ruler, plus a 10 cm ruler and a 50 cm ruler.

Half a liter bucket, one liter bucket, ten liter bucket.

One pound of weights, half a pound of weights, ten pounds of weights.

Since carpenter's tools had already been manufactured, rulers and buckets were made of wood, while weights were made of stone.

Although there must be errors in the manufacturing process, Yan Zheng can't control so much.

The most standard set was placed in the red room, and it could be taken out and corrected from time to time in the future.

He also built more than a dozen scales that the wild men could easily use to weigh themselves.

As for the scales, he thought it would be better to get them out in a few years.

…………

Fifteen days later, all the 1,500 acres of paddy fields were planted with seedlings selected and bred by Yan Zheng himself.

The envoys who came to Mona also saw this spectacle. They were puzzled and didn't understand why Monabu had leveled the land.

I don't understand why they filled their fields with water and planted rice in rows and rows.

Most of these tribes grow some grass seeds, but they only scatter the seeds in the ground, and they use the seeds as an additional food income.

At the same time, they were puzzled, and at the same time, they wondered if there was some new secret method in the Mo Nabu, maybe by doing so, they could make the ancestral spirit happy!

Ma Zhu also represented the envoy of their Douwei Society headquarters this time, and he had a deeper thought about Monabu.

This kind of thinking comes from his fear of Yan Zheng, and he feels that Mo Nabu can rise like this because of Yan Zheng.

Since he suffered a loss last time, he has become very concerned about the changes in Monabu.

He kept scanning with his small eyes, eager to discover something new.

He soon discovered that the armor of Monabu no longer used stone spears, but instead used a spearhead that he had never seen before.

Looking at their waists again, some of them were equipped with black and black things, but some of their whitish blades still frightened him.

When he saw a man from Monabu chopping wood with an iron axe, his eyes tightened violently, and he realized that the spearheads and the weapons on his waist were all weapons made of the same material as iron axes.

Ma Zhu only felt a tingling on his forehead, and he quietly followed the armor to the red room.

Holding the hand of the festival, the green tendons burst out!

"Monabe is getting stronger at an unimaginable rate! If they continue to take in the population, they will surely surpass all the tribes! Ma Zhu thought to himself.

The red room that can be introduced into his eyes is a slam blow to his heart!

"This ......" Ma Zhu trembled and couldn't walk the way.

This was the first time he had seen the built red house, the red bricks and red tiles were dazzling in the sun, the charming brown-red color, with a tall shape.

It made Ma Zhu can't help but want to kneel and worship, he feels that this is a house that the gods deserve to live in!

The armor on the side looked at him with disdain, feeling that this person was really pitiful, and at the same time there was a burst of pride in his heart.

Yan Zheng didn't expect that this house, which was considered a five-guarantee household type in the countryside in later generations, would actually make these savages so frightened.

After Ma Zhu walked into the red room, he found that the ground was actually covered with animal skins, and it felt a little soft when he stepped on it, and when he looked again, he found that the envoys of more than a dozen tribes had already knelt and sat down.

Yan Zheng talked to them with a smile, but the six armor soldiers behind him glanced at everyone with sharp eyes.

Ma Zhu felt a sense of powerlessness, and he understood that in today's negotiation, the rest of the tribes could basically only comply.

"The envoys from all the tribes have arrived, right?" Seeing Ma Zhu coming, Yan Zheng asked.

Ashin, who was kneeling below, immediately said, "Except for a few small tribes, the rest of the tribes have arrived!" ”

Yan Zheng glanced around with his eyes and said, "Okay, let's start talking about business!" ”

"I came to you today mainly to unify weights and measures, and weights and measures are related to the convenience and fairness of trade. In many transactions, we have also seen that many times, due to the estimation of the number of bad goods, one party suffers a loss, and one party takes advantage! That's not good, so I came up with the idea of unifying weights and measures! Everyone, please take a look! ”

From the next room, several clansmen brought out the prepared rulers, wooden buckets, stone weights, and scales.

All the messengers didn't say much, but looked at these things curiously.

Yan Zheng asked people to demonstrate, and he explained: "Everyone see, this is a ruler, divided into three specifications, when we trade animal skins, some animal skins are large, some animal skins are small, we have been exchanging things according to the number of each piece." And with a ruler, we can roughly understand that the animal skin is bigger, and the animal skin is better! ”

The two clansmen immediately used a ruler to gesture to a piece of animal skin, and after such a demonstration, many messengers showed their original feelings.

"This thing is very good, when trading animal skins in the future, it will definitely be more fair based on this thing called a ruler!" The envoy of the reed department patted the horse's ass.

Shiru, the messenger of the Ana tribe, also said: "We, the Ana tribe, will definitely trade animal skins according to the ruler in the future!" ”

Yan Zheng smiled, thinking that it was really a comprador tribe, and whatever the gold owner's father said, it was what it was.

"This thing is a bucket, and it is also divided into three specifications, mainly used to trade all kinds of grain and salt, please take a look!"

Several clansmen demonstrated it again, and the usage of the bucket was more direct, and all the envoys couldn't help but applaud after reading it.

The easiest thing to feel at a loss in a transaction is when exchanging grass seed grain and salt, and even often the buyer and seller feel that they are at a loss.

And with the tool of bucket, you can rely on bucket as a basis in the future.

Yan Zheng also asked the clansmen to demonstrate how to use the scales and stone weights, which did not arouse their more interest, but it was more convenient when exchanging animal meat.

After the demonstration, Yan Zheng smiled and said, "Envoys, I will bring these weights and measures tools back to my tribe later, and from then on, these tools should be used as trading guidelines." If there is damage, you must come to Monabe and get a new one. Any tribe that dares to alter weights and measures without permission should be strangled for their mastermind! ”

"Messengers have heard clearly, and those who alter the weights and measures will be hanged!"
