The weather in Chang'an is getting hotter and hotter, and beer, toilet water, mosquito coils and so on have become best-selling things again.

Early this morning, Han Fei came to a restaurant.

As soon as he entered, several people sitting in the corner of the restaurant were stunned for a moment, and then shouted: "Brother Han, here." ”

Han Fei looked up and saw those people, smiled and walked over.

"A few old brothers are really leisurely, drinking and chatting here?" After Han Fei sat down, he first picked up a bowl of beer to quench his thirst.

One of them said with a smile: "Brother Han works as a bookkeeper in Qinhou Mansion, I heard that there are a lot of accounts in Qinhou Mansion this year, how can you have time to come out and relax, could it be that you were driven out by the people of Qin's Mansion?" ”

Han Fei rolled his eyes: "Brother Liu doesn't miss me at all, as one of the fastest people in Chang'an City, do you think the Qinhou Mansion will kick me out?" ”

"And what are you?"

"The accounts of the Qinhou Mansion have been settled, so come out for a stroll."

The others are also the bookkeepers of Chang'an City, and they help some wealthy businessmen in Chang'an City every year, and they usually sit together and chat and drink when they have nothing to do.

They had heard of the accounts of the Qin Hou Mansion, after all, the Qin family had a lot of business, and there must be a lot of accounts, Han Fei and them finished it so quickly, they were a little unbelievable.

A group of people looked at Han Fei with a puzzled look.

"Brother Han, don't bluff us, can you really finish it?"

"That's it, I haven't heard that the Qinhou Mansion is looking for Mr. Accounts again, besides, Chang'an City is only for us Mr. Accounts, unless the Qinhou Mansion is looking for it from other places."

“…………”

Everyone asked gossipily, Han Fei laughed: "I didn't look for Mr. Bookkeeper, mainly, it was Marquis Qin who invented an abacus, this thing is comparable to the speed of four people to settle accounts, you say that we all use abacus, which is equivalent to more than a dozen Mr. Bookkeepers, more than ten days of work, we finished it in two days, so we have time to come out to drink with you." ”

Han Fei said a little proudly, but everyone heard that they were full of meat and vegetables.

"Brother Han, don't bluff us, this abacus invented by Marquis Qin is really so easy to use?"

"That's it, what is this abacus, why don't you show it to us?"

Han Fei said: "Of course it's so easy to use, if you want to see the abacus, you can do it, but the abacus is kept in the Qinhou Mansion, if you want to see it, you have to apply, I can take it out to you, after all, it's the secret weapon of the Qinhou Mansion, don't you say?" ”

Good stuff, that's something that people can look at casually?

These bookkeepers understand this reason, so after listening to Han Fei's words, they didn't ask too much, but after letting Han Fei take it out, they must let them see it.

After all, some people who are in a hurry to settle accounts, if you calculate quickly, they will use you, and you will be able to make more money.

Everyone drank wine and chatted like this.

Soon, Qin Tian's invention of the abacus slowly spread in Chang'an City.

Fifth day after lockdown.

Li Shimin was in the imperial study to review the folds, and Tang Jian, the head of the household, suddenly came in a hurry.

When Li Shimin saw Tang Jian coming, he was a little curious, and said, "Tang Aiqing came in such a hurry, but what's the matter?" ”

Tang Jian is in his forties, his body is thin, and he is an old minister of the Li family who followed Li Yuan when he was in the Taiyuan cavalry, so he is quite useful.

"Holy Lord, the minister has something important to tell the Holy Lord."

"What's the matter?"

Tang Jian hesitated for a moment, and then continued to speak: "Recently, there are a lot of accounts in the household department, but the account manager is not enough, so the efficiency of the household department is very low." ”

"Then hire a bookkeeper with a lot of money."

Tang Jian smiled bitterly and said: "Shengshang, the minister doesn't mean this, the minister means that the little marquis of Qin Tian has invented a tool for settling accounts, called an abacus, and when you calculate the accounts, you can top four account gentlemen, the minister...... I want the little marquis to teach this abacus to the bookkeepers in the household department, but now that the little marquis is grounded by the saint, Yichen doesn't know what to do. ”

Saying that, Tang Jian glanced up at Li Shimin, after Li Shimin heard his words, his expression moved slightly, and then he chuckled: "This Qin Tian, I really can't help him, if he is locked up, he can drum up things, it seems that he has to be locked up well." ”

Tang Jian's cheeks twitched when he heard this, and he hurriedly asked, "Holy Lord, what do you think of this?" ”

Li Shimin thought for a while and said, "Come on, go and call Qin Tian into the palace and ask him to bring the abacus with him." ”

Li Shimin also wanted to see what the abacus invented by Qin Tian was.

The two of them didn't wait long in the palace, and soon Qin Tian entered the palace, this was the first time he had left the palace after being locked up in the palace for five days, the feeling was very strange, as if a prisoner had finally been released from prison.

He knew that this was an opportunity for himself, and he had been waiting for this opportunity, maybe he could rely on this opportunity to regain his freedom today.

After coming to the imperial study of the palace, Qin Tian saw Li Shimin, and also saw Tang Jian, but he was not familiar with Tang Jian at all, and he didn't talk much on weekdays, so when he saw Tang Jian, Qin Tian was still a little surprised.

"Holy Lord, I don't know what happened to you Xuanweichen entering the palace?"

Li Shimin glanced at Qin Tian, but he didn't give him a good look, and said coldly: "Did you bring the abacus?" ”

Qin Tian was a little unhappy in his heart, it was really unreasonable to ask for his own things, and to treat him so coldly.

But he was unhappy in his heart, and Qin Tian didn't dare to show it, so he hurriedly took out the abacus and said, "Holy Lord, bring it." ”

Li Shimin took the abacus and looked at it, and saw that the abacus style was quite interesting, and when he moved the beads, it felt very good, but looking at such a thing, he didn't believe that this thing could settle accounts.

"That's what settling accounts?"

Qin Tian nodded: "Returning to the Holy Lord, yes." ”

After answering the sentence, Qin Tian did not continue, Li Shimin frowned slightly, a little displeased, and said, "How to use it?" ”

Li Shimin spoke, and Qin Tian stepped forward to tell Li Shimin about the usage, Li Shimin is still very smart, and he will use this thing as soon as he hears it.

And when Li Shimin understood how to use the abacus, he was suddenly shocked.

In fact, there is a limit to the speed of people's accounting, even if some people who are particularly good at mental arithmetic, it is impossible to be fast, but with the tool of abacus, it is not necessary to think about other things at all, as long as they keep calculating, this efficiency is simply against the sky.

Li Shimin glanced up at Qin Tian, he couldn't believe that this thing was invented by Qin Tian, what was this kid in his head, he could even invent this?

Shocked, especially shocked, Li Shimin's expression suddenly moved.
