Then Li Shimin saw that Li Chengqian did not respond, and said:

"Qian'er, you dare to question it, which makes me very pleased. But you must also have something to say and do, and don't belittle the hard work of the ministers so much! ”

Li Shimin was a little dumbfounded by Li Chengqian's account book just now, and at the same time, he had to see that Dai Guan's face was very ugly at this time, no matter how he said it, Dai Zhou was also a person who had followed him for many years, how could Li Chengqian be so cheap?

"It's my father, and my sons are also because they saw what was recorded in this account book and felt that there was a better way, so they brought it up."

Li Chengqian suddenly became sincere, making people wonder if the prince just now was the same, as far as Li Chengqian was concerned, Li Chengqian was very arrogant, even more fierce than Li Shimin, and now it seems that he is like a good man.

"You say, if it is reasonable, I will let them change it, if it is unreasonable, they will inevitably be punished!"

Li Shimin is very fair in doing this, and what should be is what it should be!

Dai Xuan looked at Li Shimin with very grateful eyes.

How could Li Chengqian be punished?

So he said, "The numbers used in this ledger are too backward. ”

"What do you mean by that?"

"If you look at these numbers: zero, one, two, three, four, wu, lu, seven, 捌, jiu, pick, hundred, thousand, trillion, billion, if you form a big number, you basically look at the back and forget the front! And it's very error-prone! In this ledger alone, I could cite more than 10 errors! But now it's not about the error, it's about how to fix it! ”

Li Chengqian's words directly made everyone pause, because they knew that this was indeed the case.

Chinese numbers do have this kind of depressing thing.

"I want to hear about it!"

Li Chengqian's words made Dai Xuan believe it a little, so he put down a little shelf and asked.

"First of all, take this number as an example, one thousand, two hundred, three picks, ten thousand Wu, one thousand Lu Baiqi, you see if you look at the front and forget the back."

As soon as these words came out, everyone looked at it, and if they didn't look at the book, it was really so.

Li Shimin also felt that it seemed to be the same, but he was helpless against these numbers.

There are too many things to be governed by the household department, and the numbers will be huge, unlike some small workshops, their numbers are small and can be calculated very well.

Dai Xuan nodded yes, while Li Shimin asked, "Is there a way to make it easier?" ”

"Erchen has a way to condense these fifteen words into eight words! Fewer words, fewer mistakes! Also improve efficiency! ”

Li Chengqian said this, and everyone was surprised.

Dai Xuan said: "These fifteen numbers are all inseparable, if there is one less, it is a thousand miles away!" How can it be scaled down? ”

That's a lot of numbers!

Li Chengqian didn't care.

In short, he has a way, he has a way.

"Someone, bring a pen!"

So there was a little yellow doorman who sent the pen.

Li Chengqian, on the other hand, wrote a few Arabic numerals directly on the paper.

12，345，678

These eight numbers are in a fog when everyone sees them.

What the hell are these eight numbers in their eyes? I've never seen it before.

Dai Xuan said: "Your Royal Highness the Prince, what are you writing this?" It looks like a tadpole. ”

"yes, how come we can't read what you wrote!"

For these ancients, Arabic numerals were a kind of literature that was difficult to understand, and they could not guess the location of the words.

Li Chengqian smiled, and wrote the numbers he just said, one thousand, two hundred, three picks, ten thousand Wu, one thousand, one hundred, one thousand

Said: "One thousand two hundred three hundred thousand ten thousand corresponds to 1234, and Wu Qian Lu Bai Qi picks up the corresponding 4578, combined, eight words can express the result of fifteen words." ”

Dai Xuan said again: "What are these numbers called?" We don't seem to have seen it! ”

These are Arabic numerals, and there is no Arabic name now, but it was something that was not really popularized until 600 years later.

So, he's ready to call it: Datang Numbers!

"Datang numbers?"

The crowd exclaimed, why?

Li Chengqian went on to explain:

"These are some numbers I saw in a lost ancient book, which has been explained, everything about numbers, but now it has no name, so I named him Datang Numbers!"

And Li Chengqian is not over yet, so he said to Dai Guan:

"How? Dai Guan, do you think what this king said makes sense? Those of you who are officials, you don't study some good things well, but you stick to the old rules, make such backward things, and it is difficult to read, even more difficult to write, and forget the front after reading! Are you convinced or not? ”

Dai Xuan couldn't help nodding, and was very convinced by Li Chengqian.

Just now, these people were still very arrogant and said that they wanted to see how Li Chengqian responded, but now they are all burps and dare not say anything.

Sure enough, now in a hurry, the system came with a prompt:

Dai Xuan drops three skills and attributes, please choose one of the options.

Skill 1: Dharma mastery

Attribute 1: Charisma +3

Attribute 2: Intelligence +4

Dharma mastery? What the hell?

Li Chengqian always felt that this skill had more benefits, and since it was proficient, it was directly equipped.

Back to reality

The more Li Shimin looked at Li Chengqian, the more satisfied he became.

Call it a Datang number, of course Li Shimin is willing, after all, this Datang is his own Datang.

He said: "In this way, this kind of figure is indeed a lot more convenient, and it is really exquisite. You have to learn this Datang number and promote it! ”

"Father, the sons can teach them now, let them understand, because these numbers are very simple."

Li Shimin nodded and said, "That's the best, do you understand?"

Everyone who was told by Li Chengqian just now that he didn't dare to say a word still has to listen to Li Chengqian's lecture.

At the same time, he still said: "Please ask His Royal Highness the Crown Prince to give advice!" ”

Next, Li Chengqian began to write the complete cross number on the paper, and explained the combination of them, 100,000,000,100,000...... and other combinations.

After a long time, it dawned on everyone.

Even Li Shimin sighed: "I didn't expect that what I knew just now was only a few corners, and it turned out that there was still a lot of knowledge in it." Qian'er, you're doing a good job! ”

Li Shimin is still good at this point, he knows how to learn good things, just with Li Chengqian's figures just now, he can indeed save a large part of the time of the household department, in fact, not only the household department, but the entire Datang will save a lot of trouble.

So, he promoted.

Li Chengqian also got some benefits from it and got skills, although he didn't know what it was useful for the time being.

But now he felt a lot of Buddha teachings coming into his mind.

Dai Zhou and others can be regarded as convinced.

In the end, Li Chengqian also said goodbye to everyone, and left the Taiji Palace in the eyes of everyone's worship, and next, he was going to implement this for Zou Fengchi to use.

Because he was more accustomed to looking at Arabic numerals. So why not let Datang change into what you want?
