"Not bad, really good!" Looking at the more delicate abacus in front of him, Li Jia was amazed.

The entire abacus is made of yellow rosewood, rectangular, surrounded by wooden frames, and small wooden sticks are fixed inside. The small wooden sticks are covered with wooden beads. A beam in the middle and the abacus are divided into two parts. There are two beads in the upper half of each wooden stick, each bead is five, and the lower half is five.

I also used the paint [Biquge www.sbiquge.xyz] and hung it for a few days. I could still smell a faint smell. I obviously put a lot of effort into it.

Our country's abacus evolved from the ancient "preparation". "preparation" is to use a bamboo stick as a bargaining chip to perform calculations, and then we get the 99 multiplication table, addition table, etc.

The abacus was truly formed in the late Tang and Northern Song dynasties. Li Jia had low requirements. If he improved the current situation a little, he would become an abacus in the modern sense. The magic formula for addition, subtraction, multiplication and division had long been available.

For example, the method of division: Zhu Shijie's "Enlightenment of Mathematics" (1299) "Returning to Examination"...

One is like one enters one sees one enters ten

Two-one additions are five and two-one additions are ten

Four in twenty six in thirty-eight in forty...

Like our daily catchphrase, "Two One Add to Five", comes from this.

"With this, why worry about being blinded by the world?" Li Jia was very happy and patted the table. He looked at the young Jinshi. Unexpectedly, he just said something and made a cost, which made the abacus come out hundreds of years in advance.

The method of imperial examinations is to select smart people. Smart people naturally have strong learning ability. A small abacus is naturally no problem.

"Tell me, as long as it is not an excessive request, I will satisfy you!"

Looking at Huang Dezhang who was about to stop talking, Li Jia increasingly regarded him as a treasure, water truck, tube truck, and even water mills. These things that had already appeared and had not appeared in Lingnan will be presented one by one.

These advanced things have long appeared in the Central Plains, but Lingnan is remote, with few iron tools even in slash-and-burn farming.

"Thank you, Governor, we are very happy in the Ordnance Department, and there are no requirements!"

Although Huang Dezhang is very straightforward, he also knows that if he seeks an official position with his friends at this time, it is a reckless behavior, but only wants his friends to leave an impression in front of the superiors, he will naturally be considered successful.

"But the Ordnance Department is really too remote. We like reading very much. Every month, I have less time to read at Brother Shixian's house!"

"What's the difficulty? A family has a lot of books. If you want to read it, just borrow it!" Li Jia thought it was something, but she turned out to be a bookworm. She smiled and said:

"The brother Shixian you mentioned is Hu Binwang?"

Li Jia still had some impression of this person. There were not many clerks in the Governor's Office, and they were all reserve talents, so they naturally knew.

This person is one of the few famous figures in his memory, and it is not bad.

"That's right, Brother Hu loves books and never leaves his hands for a moment. Saying a bookworm is not a lie!" Huang Dezhang said with all his heart, and when he saw the governor's look of memories, he was very happy:

Brother Shixian, I have fulfilled my mission

"I have also heard of him, the one who took the library of the Governor's Office the most diligent was him, Hu Binwang!"

Li Jia smiled.

"It's a good name and talent, but it seems to be different from Luo Binwang of the former Tang Dynasty!"

I hope this King Bin is like the previous Tang Dynasty and is loyal to the Tang Dynasty!

After a few more words of advice, Li Jia was very fond of this Huang Massacre, and even matched him with a guard, for fear of danger.

"Come here--" After Li Jia sat down, she stared at the abacus in front of her and thought about it seriously.

"Langjun--" An Guo's honest face appeared in front of him, and Li Jia smiled instantly:

"You go and find some carpenters to make sixty of this thing. Just don't ask for the average material, just ordinary hardwood, get it as soon as possible!"

"Little one understand!" An Guo smiled honestly, twisted his big butt, and prepared to leave.

"By the way, we came to Panyu City and Yongzhou to give the porridge in the process, is it still going on?" Li Jia suddenly asked. It is impossible to stop buying people's hearts, especially in the imperial capital, the heart of a country, and it cannot be careless.

"I think Panyu is also the best place for our Han Dynasty, so I don't need to give porridge!" An Guo turned around a little nervously, a little uneasy.

"It is not interrupted for a day. Panyu has many people, but there are more poor people. When we entered the Xing Prince's Mansion, others are powerful but few friends. Since there are few friends, let's take the initiative to make friends. Don't be afraid of wasting money. Our Governor's Mansion will not be short of money-"

"The little one understands--" An Guo got up seriously and bowed.

Then, I took the abacus and looked carefully. I couldn't figure out what this thing was. I shook my head. The husband always liked to make some fancy things.

It is very useful when others are puzzled.

He often wondered which star his husband had descended to earth. He only realized in recent days that it was the purple star in the sky...

After a few days, Li Xiuxian came again and came to this magnificent and large-scale governor's office, and felt a little sad.

Originally, he had some inexplicable feelings about that thing, but he was hidden in his heart and never showed it. That thing was supreme. Ordinary people would twitch all over their bodies if they thought about it...

But the Taoist priest is right! Tianyu is blamed instead of taking it. The destiny of heaven is in my Li family. The world has been in chaos for decades. People are thinking about the Tang Dynasty. In addition, the position of Governor Li is highly powerful, and it is easy to seize Lingnan.

The surrounding areas of Chu and Fujian have more than enough self-protection and insufficient expansion. The Tang State has just been seized by the Great Zhou Dynasty in Huainan, and there are all advantages in the land during rest and recuperation.

The time is here, people are harmonious, and places are good, so it is my Li family who will ascend the throne again.

As for the Li family in Jiangnan, they are just a substitute. How could they be the Li family?

"Class Chief, please come inside--"Class Chief Li came, and An Guo went out to greet him in person, very solemnly.

"Yeah!" He glanced at it, and the attitude of the patriarch Li was very satisfied. He leaned his hands on the back and entered the yard with stern eyes.

One goes up one, one goes down five goes down four, one goes up nine goes up one.

Two on two, two on five on three, two on eight on one.

Three up to three, three down to five go two, three go seven go one.

Four up to four, four down to five go one, four going six going one.

…………

"What is this?" When Chief Li entered the yard, he saw a group of scholars sliding back and forth towards a bead strung with wooden sticks, and kept reciting it in his mouth, which was extremely funny.

When did the Governor's Office have these fools?

"These are all transport envoys carefully selected by the governor and are about to go to various places!" An Guo said indifferently.

"So these are all fortune-tellers!" Clan Chief Li was shocked, fortunately he didn't say it just now.

He also heard of the fortune-teller, but he was in charge of a state's money, and he would have to deal with his own land taxes in the future.

What was the black bead? Clan Li was like a curious cat, and his heart was itchy.
