Liu Ponu slept directly into the afternoon.

“0，1，2，3……”

There was a soft reading sound from the courtyard, which was a little familiar......

"Bad old man?" Liu Ponu was stunned for a moment, then rubbed his eyes, and confirmed that the person who was reading aloud just now was indeed a bad old man.

dragged his tired body out of the door, and Liu Ponu was completely speechless by the bad old man.

I saw Liu Che, who was half white-haired, sitting on the ground without any image, ignoring the sun above his head, and concentrating on studying the Arabic numerals he had written on the ground in the morning.

As for Wang Bing, who was supposed to squat here to study.

The devil knows where he went......

"Awake?" Sensing some movement behind him, Liu Che glanced back and greeted with a smile.

"Hmm......" Liu Ponu nodded sleepily.

"Not to mention, these numbers you came up with are quite convenient, easy to learn, and don't seem to be that laborious!" Liu Che continued to turn his head to look at the Arabic numerals on the ground, and praised them without hesitation.

Liu Che had forgotten how long he had learned when he first learned words, but now it only takes half a day's work for him to recognize these twelve symbols on the ground.

And this thing can still be combined at will.,To be exact,It's only ten characters.,As long as you can completely remember these ten characters.,And then remember the corresponding position unit.,No matter how big the number is, he can quickly and easily recognize it.。

"Don't tell me you've been basking in the ......sun here for a long day," Liu Ponu rolled his eyes and said speechlessly.

"What's wrong with the sun for half a day? If you're ...... If it can be promoted, do you know how much trouble you can save in the future? Liu Che said angrily.

The advantage of Arabic numerals is that they are simple, easy to learn, easy to write, easy to read, and to sum up, the speed of transmission is fast, and the resistance to transmission is small, so it can be unified around the world in the future and become a common number symbol all over the world.

However, it is not without its problems, if the writer's handwriting is not good, it is extremely easy to make mistakes, so the official place is always re-marked with capital Chinese characters to ensure accuracy.

But Liu Ponu doesn't have the time to talk to the bad old man about popular science now, and no matter how good things are, they are just things he uses to be lazy.

Liu Ponu turned around and went back to the house, took out the account book that he had sorted out last night and handed it to Liu Che.

Liu Che, who looked confused, took the account book and spread it out directly, and turned the bamboo slip ninety degrees very awkwardly.

If he had just come in the morning, he would not have been able to read the contents of this bamboo slip, but after learning the numbers, it would have been much easier to read the ledger.

Three-stage bookkeeping is very simple, the first column is the marking, the second column is the entry, the third column is the outgoing, and the fourth column is the balance.

Regardless of whether it is recorded or discharged, the following balances must be linked to the previous column to form a causal relationship.

With the help of annotation, Liu Che can clearly know where every money is spent, how much is used, and how much is left.

"This is the general ledger, only listing the overall entry and exit accounts and balances, and the specific detailed accounts, the workload is too large, I haven't had time to do it yet!" Looking at Liu Che, who was confused and shocked, Liu Ponu showed off a little.

What's that?

Say I'm plagiarizing?

What is not copied is not at all like the words of cultural people.

If this bamboo slip is preserved, it will be dug up again during archaeology two thousand years later, and then it will be the wisdom of my ancestor who will be copied by later generations.

"Accounts?" Liu Che was stunned, this alone was enough to shock him, this was already the most detailed account book he had ever seen, could there be more details?

"Nonsense, if you want to do it, you have to do a full set, and if you want to do it, you must make a big one!" Liu Ponu looked at Liu Che calmly.

He didn't plan to hide it, after all, such a large sum of money, if there was no bad old man to cover for himself, it would be absolutely impossible for him to swallow it.

So he continued to explain: "Just like this material expenditure, there is a special sub-ledger corresponding to it, which will list in detail what materials are used in this billing cycle, how much is the expenditure of each item, in principle, only after the detailed account statistics can be copied on the general ledger, but now the mine has just begun, the cost is not much, plus it is just starting to do these, the process or something still needs to be optimized." ”

"With this bill, even if the emperor comes, it will be difficult to take a penny from the money allocated by the imperial court, as long as one place is not right, the other places will not be matched."

When he saw the general ledger, Liu Che realized the advanced and convenient nature of this thing, but he was far from expecting it to be so convenient.

If the imperial court can also keep accounts in this way, then there will be much less bad debts every year.

If you use this method from the beginning of your own rule, I'm afraid that the bad debts that you have not been able to calculate for decades will be enough to build two palaces by yourself, right?

"That's not right!" Liu Che suddenly realized that he seemed to be surrounded by this kid, and looked at Liu Ponu with a gloomy face and said, "Since you made this thing, how can you still swallow those twenty hectares of land alone?" Isn't it clear when you look at the bill? ”

Listening to Liu Che's words, Liu Ponu suddenly frowned.

How long has this been?

The dog's housekeeper leaked the news?

Even the bad old man knows, so will the emperor still not know?

"Who said I was going to take it to myself?" Liu Ponu's old face turned sideways, and he denied it extremely shamelessly: "I am now representing the imperial court, can the imperial court do the things of that robber?" I'm just saving money for the imperial court, and I'm doing this to lower the price, do you understand? Which dog day is chewing the root of the tongue behind your back? ”

"Really?" Liu Che's face was full of doubts, after all, the report was so true, it definitely didn't look like a fake.

"Of course it's fake!" Liu Ponu lowered his voice and continued: "We have been tired and tired for so long, and we have solved such a big problem with our own ability, why should the fruits of victory be made prostitutes in vain?" I can solve this problem, and the court is the biggest beneficiary, right? You can't eat meat in the court, and you won't even leave us a mouthful of soup, right? ”

"Well, that's the ......reason" Liu Che nodded very unwillingly, but he was very helpless to Liu Ponu in his heart, his own money, if he wants you, just say it, can you use such painstaking corruption? Don't be tired of panicking......

"Originally, I was going to wait for this money to get some money to give these people some to gag their mouths, but I didn't expect these people to give me this opportunity at all!" Liu Ponu frowned tightly, the development of things was indeed beyond his expectations.

If the money doesn't arrive, I naturally don't want to pay out of my own pocket, and if something goes wrong in the back, I will get the money out first, who will I find to reason with when the time comes?

But now......

Liu Ponu set his eyes on Liu Che, and said with a sly look: "Bad old man, this time the problem is on you, you lend me some money first, and I will use it to give them a gag of their mouths, if anyone doesn't want it at that time, then it is likely that he leaked the news, and then you find an opportunity to send him to a dangerous place, and strive for the kind of place where he can't come back, you know......"

"What if I find it? How are you going to swallow these twenty hectares? Liu Che, who has no money, doesn't care, he is still more curious about how Liu Ponu will operate this matter.

"The court can't prostitute in vain, it must give the Wang family money as compensation, this money must also be entered into our account first, and then given to the Wang family by our hands, and then let the Wang family write a receipt and sign the pledge, let's go to the account and transfer the money, but this money is directly transferred to my hands, one is willing to fight and one is willing to suffer, there is no problem in the accounts, they are all real accounts, as long as the emperor does not come to copy my home, no one can see the problem!"

"I explained to you in advance, you have to give me a cover for this money, in case the emperor really finds out about me, I will directly tell the emperor that you gave me, and then you can find a way to solve the source of this money......"

Liu Che looked at Liu Ponu with a gloomy face: If I hadn't been the emperor, I really wouldn't have been able to catch this pot......
