Zhao Si looked at Chu Ze incredulously, this was too outrageous.

This ruler is freshly made, it's so easy to make, right?

They weren't prepared for anything.

Facts have proved that Chu Ze really thinks so.

He knew the distance from the pole to the equator, but he didn't know how people made the centimeter ruler in the first place.

But as a child of Greater China, he grew up with a centimeter ruler since he was a child. Even if he hasn't used it for many years now, Chu Ze clearly remembers the appearance of the centimeter ruler and the distance of every centimeter, and now he only needs to draw it.

What is it called?

It's called painting a gourd, so what's not to draw?

Zhao Si quickly prepared the things, and Chu Ze found a small wire, and kept drawing on the paper to determine the distance, and strive to control every centimeter, or even the distance between each millimeter, in a suitable distance, to minimize the deviation as much as possible.

After he finished it, Chu Ze used small wires to print them on the cut cowhide one by one.

Chu Ze spent a lot of time, and the people who came outside to urge changed several waves.

Just when they couldn't wait any longer, Chu Ze came out, still holding a slender cowhide in his hand.

"Found it." Chu Ze walked in front of everyone, and waved the cowhide with his hand, and the cowhide that was rolled into a ball quickly unfolded under Chu Ze's wave, "This is the centimeter ruler that we brought from the adult." ”

The crowd gathered around in a strange way.

"This is the centimeter ruler, huh? Is this really accurate? It feels so much shorter. ”

Chu Ze said: "This is only a distance of one meter, and one zhang is about 3.33 meters, that is, three meters and three centimeters more." Chu Ze raised his hand and pointed at the centimeter ruler, telling them that these small grids were centimeters; Each centimeter is divided into ten millimeters, and when you measure it, you don't need to stretch it tightly, you just need to spread it out there.

It's the same as teaching elementary school students who are just learning to recognize centimeters.

After Chu Ze finished teaching, he continued: "This thing is convenient and easy to carry, isn't it more convenient than you taking millet out?" And if this value is used uniformly, the error will be smaller. ”

"But wouldn't someone deliberately make the ruler smaller?"

"That is, once it is done, the result is not the same as it is now?"

Everyone is still not at ease.

But Chu Ze smiled mysteriously and said: "This centimeter ruler is not just a casual drawing, but there is a fixed process, as long as this is correct, the centimeter ruler drawn will not make much difference." The small error is within the allowable range. "After all, there has been a certain error in this centimeter since the day it was made.

But no one cares.

Chu Ze said this, but he just wanted to take this opportunity to make a dozen Ming famous.

At that time, after the Ming army landed on the island, it could dispel everyone's resistance to the Ming to a certain extent.

Thinking of this, Chu Ze worked harder to promote Da Ming.

What kind of water mill stone grinding water wheel and so on, Chu Ze told them all vividly, and finally took out the gear gadget he made before he came.

Everyone looked at this delicate thing and was excited.

Suddenly, someone touched his chin and said: "I heard that the envoy of the Ming Dynasty is in Ryukyu these days, in fact, a young one is surnamed Chu, and I heard that that person seems to be Chu who has invented a lot of things...... Chu, Chu Ze? My lord, is this you? ”

Chu Zexin said, you guys are quite well-informed.

"Exactly down there." Chu Ze raised his chin very immodestly.

When the man heard this, his eyes lit up.

He hurriedly stood up and bowed deeply to Chu Ze: "I have heard the name of the adult a long time ago, and now I see it like a rumor." ”

"Oh, what's the rumor?" Chu Ze really wanted to hear how the people outside passed on him.

The man gave Chu Ze a thumbs up and replied briskly: "Lu Ban is not as good as you in the world!" ”

"Hahahaha...... It's been a prize, it's been a prize. Chu Ze waved his hand modestly, but the smile on his face was about to fly.

This is complimenting him.

Who doesn't like to be complimented?

Chu Ze was so praised that his tail was about to.

At this moment, someone suddenly said: "Lord Chu, why don't you tell us about what other good things Daming has, let us listen to it too." ”

"It's just that although we haven't been to Daming, we've heard a lot, and I really want to know what it's like over there."

"What is it?" Chu Ze touched his chin and thought for a while, and said, "It's very big, the land is vast and sparsely populated. Daming has a lot of products that I have, porcelain and silk are very famous, and there are ......" Chu Ze thought of where to say, and the main compliment.

By the way, Daming has something new, and he also picked out what they were interested in.

In order to reflect Daming's goodness, he even found a scene to transform a toy for a child.

Looking at this new toy, don't say that the children, even the big friends sitting there can't help but be hot, if it is not really embarrassing, they are afraid that they want to grab it, and they will study it themselves.

Chu Ze talked a lot to them, and he didn't leave until it was getting late.

Although it is just talking, it is also tiring.

Chu Ze rubbed his temples and walked into the room.

As soon as he entered the room and was about to wash up, there was a knock on the door.

He thought it was Zhao Si, and said directly: "Come in." ”

The door was pushed open from the outside, and footsteps were heard coming in.

It's very light, but also a little restrained and cramped.

This is not Zhao Si.

Chu Ze looked at it suddenly, a pair of dark eyes burst out with cold light, and stabbed towards the person at the door, and the person in the future straightened his body instantly, his hands were twisted together, and he looked at Chu Ze in panic.

"Ya'er?" Chu Ze was slightly stunned, "How did you find it?" ”

What about Zhao Si?

He asked him to watch at the door, and this man dared to leave without permission, and let people break into his room.

Chu Ze's face was a little dark, and he thought to himself, when Zhao Si came back, he would definitely clean him up.

Then Chu Ze heard Ya'er speak eagerly: "My lord, I don't know what you are here for, but I know that you must have something to do here, thank you for today's matter, if there is a need, I will be happy to serve." As she spoke, the girl bent down deeply and bowed to Chu Ze.

Chu Ze didn't care.

What does he have to do, what can such a little girl help with?

But people were kind, and Chu Ze didn't refuse directly, but said, "Okay, if there is a need, we will look for you." ”

Ya'er instantly smiled with a relaxed smile on her face when she heard this.

"Okay, I'll wait." Ya'er said her address again, then bowed to Chu Ze again, turned her head and ran away, her back was visible to the naked eye.

As soon as she left, Zhao Si also returned.

Chu Ze looked at the doggy person at the door, and shouted with a dark face: "Zhao Si, you let Master Ben come in!" (End of chapter)
