After Arabic numerals became popular, the bookkeepers began to record some of the accounts in bound books.

Originally, bamboo slips weighing hundreds of catties or even thousands of catties now only need a dozen account books, which is so convenient.

Not only have those bookkeepers now worked a lot more efficiently, but they also have more free time, and they are not particularly tired.

"The prince is really amazing, he invented paper, he invented Arabic numerals, and now our work is much easier than before."

"Who said no, after having the prince, our household department is really idle."

"Yes, the work that was supposed to be half a year can be done in a month, everyone hurry up and go have a little wine later."

"Yes, yes, drink a little wine......"

In the past, they were busy settling accounts all day long, and they had time to drink, but now it is different, and working half a day is more efficient than working a few days before.

In this case, you can also go for a drink in the afternoon, and if you have a little spare money, it is also good to go to Fireworks Lane to find a girl to have a good time.

While these people were busy settling accounts, Li Yu and Lu Tong walked in from outside.

As soon as these bookkeepers saw Li Yu, they were immediately happy, even happier than seeing Lu Tong.

"Oh, the prince is here......"

"The prince is here......"

Several bookkeepers immediately surrounded Li Yu, Li Yu didn't expect him to be so popular.

"Alright, everyone, please take a seat, this king is here today just to promote this thing to you." As he spoke, Li Yu took out the abacus.

Seeing the abacus, Mr. Bookkeeper was stunned for a moment.

"Lord Wang, what is this?"

Lu Tong suddenly frowned, "What do you mean by what is this, this is an abacus, used to settle accounts." ”

A group of bookkeepers looked at each other.

"Lord Wang, can this thing settle accounts?"

"I think it's pretty much the same with a paperweight."

“…………”

Mr. Bookkeeper couldn't help but complain, one looked down on the abacus more than the other, Lu Tong listened to it, and he wanted to smoke people, but it was Li Yu, who was very calm.

"It seems that a few people don't believe that this thing can settle accounts, so let's take out an account book, and you will calculate it together, and this king will use this abacus to calculate, see who calculates accurately and quickly, how about it?"

"What does the prince mean to compare, and you alone compare with how many of us?"

Li Yu nodded, "Exactly." ”

The bookkeepers looked at each other, but agreed without much hesitation.

Settle accounts, that's the guy they eat, Li Yu wants to compare with them with an abacus, that's too much to underestimate them.

Soon, one of them came up with an account book that had not yet been calculated.

"Lord Wang, we haven't even counted this account book yet, how about we use this to compare?"

Li Yu nodded, "No problem, let's start now." ”

Don't talk nonsense, the two sides start directly, Mr. Accounts here, is a small half of each person, that is to say, each person may have a few pages of accounts, and finally everyone adds the total amount of their calculations, which is the final result.

In their opinion, their speed is definitely the fastest, and even one of them may be faster than Li Yu, but Li Yu actually wants to compete with them, isn't this looking for a loser?

But when they were counting like this, Li Yu didn't think about it, and moved on the abacus with both hands.

After about a stick of incense, the bookkeeper had already calculated half of it, but at this time, Li Yu stopped.

When several bookkeepers saw this, they were stunned for a moment, but they didn't ask, and continued to calculate, and after they calculated like this, they added it again.

As soon as they added it, Li Yu said, "But 135,674 taels." ”

After this number was said, several bookkeepers were stunned and stunned, and their mouths opened wider and wider.

"Lord Wang, you ...... How do you know? Now these bookkeepers are about to treat Li Yu as a half-immortal, Li Yu pouted, "Naturally, it's calculated, is it a guess?" ”

Guess what's possible?

At this time, a few bookkeepers are not calm, there are so many of them, and the time spent is half of Li Yu's, so the result is calculated, is it better than a tool for so many of them?

Several people looked at each other, their faces a little ugly.

But then, one of them suddenly ran towards Li Yu, "Lord Wang, how can you use this abacus, it's really so powerful?" ”

As a bookkeeper, it is actually very annoying to shout with numbers every day, especially when calculating, if there is something that can shorten their calculation time faster, they are very willing to accept it.

And when one of them ran over, the other people naturally followed suit.

This kind of result is the result that Li Yu really wants to see, he put the abacus on the table, and said, "The abacus is naturally very powerful, if you are willing to learn, I can teach you, you have a foundation, you will be able to learn it soon." ”

"Of course I'm willing to learn, of course I'm willing to learn......"

Mr. Bookkeeper's enthusiasm was very high, and Li Yu naturally taught them patiently, Lu Tong watched from the side, and admired Li Yu more and more.

When Li Yu was teaching here, he was a little hesitant in his heart, and now, the paper, abacus, and Arabic numerals have all come out, so did he also get out the loan bookkeeping?

It would be more accurate if this thing was calculated.

However, after thinking about it carefully, Li Yu felt that it was better not to do it for the time being.

The credit bookkeeping method, the calculation is very accurate, and it is not easy to make false accounts, which is naturally a very advanced bookkeeping method, but at the same time, if it is implemented, it will also expose the fake accounts in many places.

It is impossible to say that the accounts of many departments and places in the Tang State are innocent, and even the household department does not dare to say that it is like this.

If he gets the loan accounting method out, I am afraid that it will affect the interests of many people in the Tang Kingdom, and at that time, it will be quite unfavorable to himself.

He is not the crown prince yet, let alone the son of heaven, offending too many people at this time, it is basically equivalent to missing the position of the prince.

When the water is clear, there are no fish, and people sometimes have to pretend to be confused, at least until their strength reaches the state of doing that thing, they have to be confused all the time.

The loan bookkeeping method must be done, but after he completely controls the Tang Kingdom, and no one can oppose him, at that time, the loan bookkeeping method can be implemented throughout the country.

Li Yu taught those bookkeepers in the household department for two days, and after two days, they had mastered the use of the abacus, and as long as they mastered the rules of the abacus, the others would be bypassed, and Li Yu didn't need to teach them.

And at this time, something happened to the Criminal Department.
