I really don't want to be a rebel [infrastructure]

Fortunately, Cheng Jingwei didn't think too much, Luo Shixing worked hard to explain with his little head: "These are abbreviated numbers, didn't you notice that they have very few strokes?"

number?Cheng Jingwei was a little surprised: "This is actually a number?"

Luo Shixing nodded vigorously: "Yes."

He pointed to the numbers and read them to Cheng Jingwei from one to ten, and then explained: "This is easy to write, and it is easy to calculate. If you write these numbers, it will take a lot of time to write these numbers, and it is too troublesome to calculate."

Luo Shixing praised himself while talking, um, this explanation is perfect, after all, he was tired of writing with a brush at a young age.

Cheng Jingwei glanced at it and asked the most difficult question: "Then how did you come up with this symbol instead?"

Except for the one that represents one, the rest of these symbols have nothing to do with Chinese characters. Could it be that they are written somewhere else?

But Luo Shixing had never been to other places, so how could he know?

Luo Shixing closed his eyes and turned his attention: "Oh, this... I once met a Gupta businessman and learned a little from him! It's just ten numbers, it's quite simple."

The so-called Gupta is the India of this era, and India at this time is under the rule of the Gupta Dynasty.

Yes, although it is called Arabic numerals, it is actually invented by Indians.

And it was invented very early, it appeared as early as the third century AD, and it didn't start to spread to the surrounding area until more than 700 AD.

Although there are still more than ten years before 700 AD, India and Datang itself are in business.

It's just that the reason why Arabic numerals did not spread in Datang is also very simple. Datang has its own characters, and it is a kingdom of heaven, so how could it learn other people's characters?

As for why the numbers invented by the Indians were finally called Arabic numerals, it is also a sad story, because the Arabs later occupied the Punjab region. After the Arabs discovered that the numbers here were developed, Indian mathematicians were arrested and forced to work in Arabia after decades. Spread this knowledge to the locals.

Including, but not limited to, mathematical symbols and systems and calculation methods specific to India.

Because of its simplicity, Arab merchants also followed suit, and then spread to farther places through these merchants.

So everyone only remembers that these were brought by the Arabs, but no one remembers who actually invented them.

Nothing has happened yet, but the Arabic numerals have appeared, giving Luo Shixing a room for interpretation.

Anyway, Cheng Jingwei won't know if he really met the Indian businessman.

Cheng Jingwei was a little surprised: "Can you actually speak Gupta?"

Luo Shixing was stunned for a moment, deeply feeling that a lie needs countless lies to be true.

Especially when you meet a smart person like Cheng Jingwei who is more active in thinking, he can really find any loopholes in your words.

Luo Shixing had already passed countless tearful cats and cats' heads in his heart, but he said, "No, no, I can't, it's because my father knows a little bit. I was young at that time, so I was by my father's side."

Well, our good comrade Luo Binwang no longer knows where he is, and he doesn't even know whether he is alive or dead. He is indeed a good candidate to come out to help his son take the blame.

Luo Shixing hoped with trepidation that Cheng Jingwei would stop asking questions, his brain cells died faster than calculating various formulas for brick kilns!

Cheng Jingwei thought that he was thinking of his father again when he saw his languid appearance, and hurriedly said, "Okay, okay, don't talk about this, you continue to count."

Sure enough, after he said this, he saw that the little lynx became more energetic.

Only then did Cheng Jingwei heave a sigh of relief, but what he didn't know was that Luo Shixing was also heaving a sigh of relief. It's great that Cheng Jingwei didn't keep asking.

But he can't be too happy too early. Later, he will find a way to record the lies he made up, or if he accidentally slips up one day, which is different from what he said now, he may be upset.

With Cheng Jingwei's memory and IQ, Luo Shixing has no doubt that the other party may still remember what he said now in 20 years!

Luo Shixing lowered his head and continued to count. Cheng Jingwei watched him write a bunch of words, such as the two horizontal bars behind the effective volume of the tunnel kiln, and then the hourly finished product output and firing time, as well as the finished product rate and kiln loading density.

To be reasonable, he knows each of these words separately, but he doesn't know any of them together!

Sitting by the window, Cheng Jingwei began to ponder whether he really had learned too little or not. Before he was exiled in the previous life, he really didn't like reading, but he also read a lot of books afterward.

The main reason is that if you don't read books, those civil servants tell him that it is easy to be tricked into it.

Cheng Jingwei also suffered a lot to understand this truth, and then frantically studied culture lessons.

Living a new life, he originally thought that those hours could be saved to do something else, but why does he feel like he is illiterate every time he reads what Luo Shixing wrote?

In fact, Luo Shixing was also very painful. Originally, he could use various symbols to replace those nouns. For example, the effective volume of a tunnel kiln can be used as V, and the hourly finished product output can be used as G.

But he didn't dare, he was afraid that Cheng Jingwei would ask him where these words were written, and he would still make up lies when the time came.

If you tell too many lies, it's easy to forget what you said, and then it will be full of loopholes.

Luo Shixing is not stupid, how could he do such a thing?

However, the result of using all Chinese characters and traditional characters is that after the calculation, Luo Shixing didn't feel how tired his brain was, his hands were tired!

He wrote the calculated results on another clay tablet and said, "Hey, it's too troublesome to use clay tablets every day."

Writing on a clay tablet is naturally easier than writing on a bamboo one, but the clay tablet needs to be faster. Once it dries, you can’t write again, and you have to be careful not to make mistakes.

If it is in a wet state, it can be corrected if it is wrongly written. Once it is dry... let's do it again!

Cheng Jingwei picked up Luo Shixing's cat's paw and looked at it carefully, and found that his thumb, index finger, and middle finger were all red. He kneaded the cat's paw and said, "Go back and ask Ale for some paper."

Luo Shixing said decisively: "Forget it, forget it, paper is too precious, if I use it too much, I'm afraid that if I sell it, I won't be able to pay back the money."

Cheng Jingwei teased him and said, "That's not the case. If you exchange one for one, at least you have to weigh it."

After finishing speaking, he patted Luo Shixing's belly, smacked his lips and said, "No, it seems to be really bad, your little arms and legs don't have much flesh."

In terms of weight?When is he?Piggy?

Luo Shixing withdrew his paw and unleashed his deadly cat fist.

After the two scratched each other, Cheng Jingwei directly hugged Luo Shixing and lay down and said, "Okay, stop making trouble and go to bed!"

Luo Shixing was also a little tired. He was exhausted every day, so he quickly closed his eyes and fell asleep.

In the dream, he turned into a lynx and sat on the scale, and Cheng Jingwei turned into a tiger and was bargaining with Alezhen. One said that this lynx cub weighs 25 catties, and you have to give me 25 catties Paper!

The other one insisted: "One catty is 16 taels, which is obviously a little more than [-] catties. If you round it up, I will give you [-] catties of paper!"

Luo Shixing was very angry immediately, and slapped the two of them flying with his paw, then jumped on a stack of papers, lay down and licked his paw happily: These are all his!

When he was very happy, he suddenly felt that his breathing was not smooth, and his nose seemed to be pinched by something. When he woke up in a daze, he saw Cheng Jingwei pinching his nose with his paw that needed to be beaten.

Luo Shixing's body reacted faster than his brain, and he punched him with a punch. Cheng Jingwei withdrew his hand in time and said with a smile: "Did you have a dream, and your saliva will come out from laughing."

After hearing this, Luo Shixing touched the corner of his mouth subconsciously, and then found that the corner of his mouth was clean where there was no saliva.

He rushed over to do another set of Maomao punches, and Cheng Jingwei pinched his neck and rushed him to wash up. While washing up, he mumbled, "Dream sold you for a good price."

After thinking for a while, he added: "The kind that weighs by the catty!"

Cheng Jingwei almost swallowed the mouthwash when he heard it, this little lynx is quite vengeful!

After the two of them fought and had breakfast, they still did their own thing. Cheng Jingwei stayed to help him make the model, while Luo Shixing ran to the site of the brick kiln and directed the slaves to build the brick kiln.

Now he can also communicate with the locals without relying on other people's translation, but those professional terms are still very troublesome, especially when many things are said, these slaves can't understand.

After Luo Shixing calmed down for a while, he began to instruct them with the data he had calculated, such as how wide the grooves should be here and how they should be built there.

Because the overall brick kiln is not very big, he calculated that it would take about half a month to complete.

In addition to this is the problem of kiln cars.

Then he found that this seems to be more difficult to solve than the track.

A wooden car will turn into ashes when it goes in. If there is no metal... how can I get a kiln car?

It doesn't need much, he calculated, as long as there are six one-meter-long kiln cars are enough.

When Cheng Jingwei went to see Luo Shixing at noon, he saw the little lynx sitting on a tree stump eating rice balls from a distance, his cheeks bulging with gray marks, but his expression was still serious, and he looked extremely happy.

Luo Shixing was a little surprised when he saw Cheng Jingwei: "Why are you here?"

Cheng Jingwei took out a cloth towel to help him wipe his face and said, "I'll come over to see you when the model is finished."

Luo Shixing was so surprised that the rice ball in his hand almost dropped: "So fast?"

Sitting beside him, Cheng Jingwei imitated his appearance and said with his legs shaking, "It's not too soon. You need to get the bamboo tube you mentioned. I don't know how to pretend."

Hearing this, Luo Shixing wished he could go back and install the bamboo tubes immediately, but he still had to watch over the brick kiln, so he could only sigh and said, "Let's talk about it when I go back."

Cheng Jingwei glanced at the slaves and asked, "What's wrong? Are they disobedient?"

Luo Shixing gave Cheng Jingwei a strange look, how did he switch to the language of the Ouluo tribe?

But he didn't think much about it, he just thought that Cheng Jingwei was exercising his speaking ability, but he didn't notice that the slaves collectively paused for a moment after hearing this sentence, with a look of fear on their faces, several of them wanted to go to this place. While watching, he stopped his movements and lowered his head as if waiting for the verdict to be pronounced.

Luo Shixing said casually: "No, it's just that there are many things they don't understand and they need me to talk about it. After a long time, I feel that my mouth is dry."

Cheng Jingwei immediately said: "You tell me, I'll tell them."

Luo Shixing looked at him and suddenly smiled, and handed over a clay tablet: "You come."

Cheng Jingwei took it over and found that the clay tablet was the clay tablet filled with nouns he couldn't understand yesterday.

After a pause, he calmly handed the clay tablet to Luo Shixing and said, "It suddenly occurred to me that I forgot to put the dismantled waterwheel on. I'll help you when I finish it."

Luo Shixing looked at his back and laughed loudly: "Don't go, I will do that too!"

Then Cheng Jingwei's steps became faster, and it seemed that he could still hear the crisp laughter echoing in the forest until he got home.
