The temperature in Chang'an City today is very low, and although there is heating in the Xuanzheng Palace, it is far from reaching the level of heat.

Dai Xuan stood in the middle of the temple, but sweat began to break out on his forehead.

I haven't reported the statistics to Your Majesty yet, why is there an account book on Your Majesty's royal table?

Could it be that someone in the household department skipped his own book and reported it to the next level?

That's not right, the data from the two groups, although very similar to this ledger, is not exactly the same.

Besides, the handwriting on this ledger is a bit naïve, and there are some Arabic numerals, which is obviously not the style of the household officials.

"Dai Aiqing, do you think this data is accurate?"

Li Shimin's mood is even more complicated than Dai Guan.

When Li Zhi gave this account book to himself a few years ago, he didn't pay attention to it at all, and he didn't believe that Li Zhi could complete the statistical work that took half a month to complete in just two days.

Naturally, he would not believe the numbers on the ledger either.

It's just that the number of 15,430,000 guan is really bigger than I imagined, so I have some impressions.

Now, I heard from Dai Guan's mouth that the data counted by the household department, although it is not yet the official version of the report, but the two data are highly similar to Li Zhi's account book, which is very revealing.

In this world, how can there be so many coincidences?

"Your Majesty, originally Weichen thought that the data counted by the two groups of the household department might have double-counted the taxes of some states and counties, but when I saw Your Majesty's account book...... Dare to ask Your Majesty, where did this account book come from? ”

Suddenly, Dai Zhou remembered that he had made a bet years ago.

It can't be true, right?

Impossible!

There are so many officials in the household department, and the first version of the data has just been calculated, and His Royal Highness the King of Jin has already handed over the final account book to His Majesty?

This doesn't make sense.

"It was given to me by a young slave!"

Hearing the answer from Li Shimin's mouth, although Dai Xuan had already expected it, he still felt that it was difficult to accept.

Is this what you are losing?

So many people in the household department lost to His Royal Highness King Jin alone?

If this gets out......

Is it really old?

"The young slave gave me this ledger a few years ago, but at that time I thought he was writing the data blindly and ignored ......"

Li Shimin made up for it again, which made Dai Zhou depressed and wanted to vomit blood even more.

This account was there a year ago?

Could it be that His Royal Highness King Jin really calculated the result in two days?

Dai Zhou felt a little dizzy!

He pinched his arm.

It hurts!

It's not a dream!

"Your Majesty! Can you let His Royal Highness King Jin come over, and Weichen will ask in person. ”

It was still difficult for Dai Zhou to accept this reality, and he couldn't understand how Li Zhi could complete the statistics in such a short time.

If you want to say that he is scribbling, this large number is the same as the statistics of the household department, and it is impossible to scribble it just to write this number.

"Lan He, go and call King Jin over."

Li Shimin felt that at this time, it was really necessary to ask Li Zhi to come over and ask what the situation was.

In the Xuanzheng Palace, there was an eerie silence for a while.

Whether it was Li Shimin or Dai Guan, they didn't speak, they were thinking about their own thoughts.

"I've seen my father!"

Li Zhi lived in the palace, but soon came to the Xuanzheng Palace.

However, looking at his appearance, the mood doesn't seem to be very high.

Since the last time he worked hard for two days with passion, Li Shimin didn't react at all, and Li Zhi's mood was a little low.

Of course, it is not that there is no reaction, but that Li Shimin does not believe the calculation results provided by Li Zhi at all.

This devastated Li Zhi very much.

"Ahem!"

Li Shimin coughed twice in embarrassment, but before he could speak, Dai Zhou couldn't help it first.

"His Royal Highness King Jin, are all the data in this ledger calculated by you?"

Although he already knew the result, Dai Xuan still took the account book and asked Li Zhi again, hoping to hear a different answer.

"Yes! Didn't you give it to your father more than ten days ago? ”

As soon as Li Zhi looked at the things in Dai Guan's hand, he knew what he was calling over for today.

"What? Is the data of the household department also calculated? ”

"It's almost out."

If there is no version of Li Zhi's data, Dai Zhou may feel that the data of the household department still needs to be verified, but when he sees that everyone's calculation results are similar, the significance of verification is not so great.

It's nothing more than tens of thousands more or tens of thousands less, how to verify it is just like that.

After listening to Dai Xuan's words, Li Zhi's face changed slightly, and he was a little looking forward to the results of the calculation of the household department, "Dai Shangshu, what is the result of the calculation of the household department?" Is there a big difference with this king? ”

"Child, I ask you, how did you calculate so much data in two days?"

Li Shimin saw Dai Zhou standing there a little embarrassed, so he opened his mouth and asked the question that both he and Dai Zhou wanted to know.

"It's easy."

Li Zhi was not stupid, he had already guessed something, and a smile began to appear on his face.

"I just used Arabic numerals to rearrange and transcribe the account books of the state capitals, and then according to the bookkeeping method taught by the second brother, I used the abacus to calculate, and then I calculated it."

Seeing Li Zhiyun's breezy appearance, don't mention the uncomfortable feeling in Dai Zhou's heart.

The point is, I can't refute anything yet.

As for those Arabic numerals, I haven't heard of them.

But the people who really use it in Chang'an City are basically the people related to the Chu Palace.

Could it be that these Arabic numerals are really so powerful?

"Abacus? Could it be that there are a bunch of pillars inside that wooden frame? ”

Li Shimin seemed to have the impression that Li Zhi used to crackle and move on top of something.

"Abacus? You didn't use arithmetic calculations? ”

After Li Shimin's reminder, Dai Zhou also found that several new things appeared in Li Zhi's words.

Aside from the Arabic numerals I've heard of, this abacus seems to be the first time I've heard of it.

"I don't have to calculate, it's something that only three-year-olds use." Li Zhi said with an arrogant face: "This abacus is already a necessary calculation tool for all accounting rooms in the Second Brother's Mansion, with it, the calculation that could only be completed in an hour is now completed in two quarters of an hour." ”

"Lan He, you go to the side hall and bring the abacus."

Although Li Shimin had seen Li Zhi use an abacus before, he didn't notice that this little thing could greatly speed up the calculation.

Soon, an abacus made of delicate sandalwood appeared in front of everyone.

At this time, sandalwood was far less valuable than that of later generations, and it was not a luxury to use it to make abacus.

"His Royal Highness the King of Jin, can you show Weichen how this abacus is used?"

Although Dai Zhou felt that he had never been so ashamed as he was today, he was still very eager to learn when he saw something that had the potential to greatly improve the speed of calculations.

Looking at the entire Chang'an City, there is no yamen who needs this kind of thing more than the household department, right?
