27 First-class overlord sets standards

Meizi and Laura had a fight, and then happily went to the study to find Cao Yu.

Meizi and Laura have not known each other for a long time, but they seem to have known each other for a long time, and they have a long-lost feeling of intimacy, like real sisters.

In the southwestern border of this distant western continent, they are all from other races and seem to easily regard each other as their own people and as confidants.

"Master, we're here to report!" Laura shouted from a distance, carefree.

"Worry, don't disturb the coach's work." Meizi murmured.

"Oh, isn't you remembering this for the handsome guy?" Laura's lips curled, revealing a playful curve.

Because I was about to arrive at the study room, Meizi couldn't argue, so she just walked quietly.

The two of them quickly walked into the study.

Cao Yu is busy.

He was fiddling with a few things, picking them up and looking left and right.

There are three types of things he is fiddling with: one is a ruler, one is a balance, and the other is a wall clock.

These three things are very ordinary. If you are on the earth, you can buy them with money, and the ruler will cost a few dollars, and the balance will be about one or two hundred, and the wall clock will be more expensive, but because it is not a luxury item, it will not exceed one thousand.

Cao Yu had completed several system tasks in a row, got some points, and also obtained some points through lottery and other things.

These points are not too much, about 100,000, but you can also buy some things in the system mall. If you are buying ordinary soldiers, you can buy ten, if you are buying scouts, you can buy about three, if you are special forces, you can buy two, if you are buying rifles, such as Li Enfield Rifle 2.0, you can also buy a few, and of course, you can also purchase other supplies.

But Cao Yu thought about it for a long time, but finally decided to purchase a batch of measurement tools first.

There are also measurement tools in this world, but the measurement units are blooming. Not to mention Zhongzhou, there are dozens of types in Xizhou. Even Chuzhou sometimes encounters multiple units when buying things. So before buying things, you must ask clearly what unit the other party is talking about. Just like on the earth, if you ask someone how much this kind of thing costs, you must ask clearly whether it is a market kilogram or kilogram, otherwise it is very likely that the mute eats coptis and cannot say anything about it.

Others may not think that the problem of the overflowing units of measurement is that others may not think, but Cao Yu knew that this was actually a big problem. It can even be said that whether the units of measurement can be unified is directly related to whether he can unify the world in the future.

Therefore, he planned to do this first, because the unified unit of measurement is something he can do at present, and it is not expensive but has far-reaching significance.

None of them.

So he used those system points to purchase some measurement tools.

At this moment, he was watching with a ruler.

He was looking at whether the scales on these rulers were exactly the same as those on the earth!

He was observing and Laura and Mei Zi walked in.

"Masterman." The two of them shouted, one gentle and the other carefree.

Laura had sharp eyes and soon discovered the weird things in the study: "Master, what is this?"

She walked over in two steps, and immediately squatted down and started fiddling with her.

Meizi was also very curious, so she came over to watch.

"This is a ruler, this is a balance, also called a name, this is a clock." Cao Yu explained one by one.

"Rules? Balance? Bell?"

Meizi and Laura were both stunned.

When they picked it up and observed it carefully for a while, they immediately discovered more problems. The units of these things are different from those of Chuzhou, or other units in other parts of the world.

"Master, why is this ruler different from what we have seen?" Laura asked directly.

"This is a brand new unit of measurement. You see, this length is one meter, the small grid is one centimeter, and the smallest one is one millimeter, and there are still microns below millimeters, but microns are too small, and our ruler cannot reflect it. One meter is equal to one hundred centimeters is equal to one thousand millimeters." Cao Yu explained carefully.

"What about this?" Laura pointed to the balance.

"This is the weight weighing, the basic unit is grams. Look, this is a weight of one gram... Well, this... this weight is commonly used in our lives. kilograms, and one such weight is equal to one thousand small weights! So it is called kilograms."

"What about this?"

"This is a clock, called a clock. Look, this is the hour hand, this is the minute hand, this is the second hand, one hour is equal to sixty minutes, and one minute is equal to sixty seconds. The hour hand turns one round, which means that after twelve hours, the minute hand turns one round, one hour, and the second hand turns one round, just one minute. The hour hand turns one round like this, it takes half a day, so there are twenty-four hours a day."

Laura and Meizi were both surprised and strange when they heard this.

"Master, you made all these by yourself?"

"Are you almost the same? But I asked my friend to help you customize the tools. I sent them together during the last airdrop." Cao Yu said ambiguously.

There are no such things here, and if he doesn't say he invented them himself, he can't explain it

"Master, don't we already have these things? Why do we have to make one of them yourself?" Laura asked again, curious about the baby's appearance.

"I want to unify the units of measurement first." Cao Yu smiled and paused. He said, "Oh, by the way, you have to help me with this matter. You can help me think of ways to see what to do to promote the progress of this matter as soon as possible so that the people of Chuzhou can accept this thing."

At this time, someone outside the door shouted: "Report!"

"Come in!"

"Master, the captain of the teaching team is looking for you!"

Cao Yu was stunned, then stood up and said to Mei Zi and Laura: "You guys watch first, I'll go out."

Cao Yu went out soon.

Soon only Mei Zi and Laura were left in the study.

"What does the Grandmaster mean? Why do you have to make these things? Meters? Kilograms? These things are so difficult to pronounce. Isn't it good to use the original things?" Laura was puzzled and couldn't help but mutter.

Meizi didn't say anything, just frowned.

"What are you asking?" Laura poked plum.

"I think the coach must have a deep meaning in doing this!"

"Is it very profound again? What is the profound meaning? How deep is it? Where is it deep?"

"Sister, I'm serious." Mei Zi gave Laura a blank look, a little dissatisfied.

Laura laughed, but soon restrained her hippie smile and asked, "Then why did the Grandmaster do this? Isn't it good to use the original ones directly? Even if you want to unify it, then just go to the next order. The entire Chuzhou is only allowed to use our local ones. Why do you have to get another set of things? It's so troublesome!"

Meizi didn't say anything, just lowered her head and looked at the ruler in her hand. I don't know how long it took, but her eyes suddenly lit up: "I understand!"

"What?"

"Do you still remember the quote from Da Zheng that you told me before? There is a sentence in it."

"What's the matter?"
Chapter completed!
