"Fang Xiang, are you feeling a little unwell?"

"It's okay!" Fang Xuanling shook her head at Du Ruhui, who cared about her.

Last night, I finally finished learning abacus and multiplication tables at Tang Ping's place, and then I was left to eat.

Fang Xuanling's mouth watered when he ate that chicken, but this morning he felt like he was suffering in his stomach.

That kind of spicy food, if you keep eating it, you will only feel satisfied at the time, but it will feel even spicier when you stop.

He wasn't good at eating spicy food. Yesterday, he couldn't help but eat too much because of his thirst for food. As a result, his stomach and intestines were still as uncomfortable as the sea.

"Then let's go, it's time to go to court!"

Let's go to court, it's not like there are so many things happening every day.

For example, today, there is nothing much going on except urging the Ministry of Rites to follow up on the trade progress with various countries.

Just when Li Shimin was about to retire, Fang Xuanling stood up.

"Your Majesty, I got a treasure yesterday!"

"Oh?" Li Shimin looked at Fang Xuanling with interest and asked, "What kind of treasure is it?"

With a clattering sound, Fang Xuanling took out the abacus that Tang Ping had given him yesterday. It felt uncomfortable to put this thing in his arms, but it felt much better when he took it out.

"This thing is called an abacus. It is a more convenient thing than calculation chips. With this thing, the speed of calculation can be greatly accelerated."

Li Shimin looked at it carefully, and he felt that the style of this plastic abacus came from Tang Ping.

"How fast can this thing calculate?" Dai Zhou, the Minister of Household Affairs, asked.

If we want to say who among these six departments counts things the most, then it must be their household department.

"It doesn't matter if it's three to five times faster. Once you become proficient, it can be ten times faster!"

This is the conclusion Fang Xuanling came to after getting started yesterday.

Don't think the ancients were stupid, they just may not understand some things due to limited horizons and other reasons, but their learning speed is definitely not bad.

Especially for someone like Fang Xuanling, who was awarded Jinshi at the age of eighteen, his memory is definitely far beyond that of ordinary people.

So it only took him one afternoon and one night to master the abacus.

What is the concept of ten times? Let alone Dai Zhou, no one in the civil and military circles in the Manchu Dynasty believed in it except Li Shimin.

Soon, two people from the inner treasury and the household department who were the best at arithmetic were called up.

Dai Zhou took out another account book: "This is part of the transaction. The total price has not been calculated yet, so I don't know the answer, so I'll trouble you three."

Nei Ku and Hu Bu still haven't figured out what's going on, but this is a demonstration of their ability in front of the emperor. If they can be appreciated by Li Shimin, wouldn't their meteoric rise be just around the corner?

As for the house astrology, just wait for him after a while, just be a little ahead. They still know this about human nature.

Then the hall became quiet, except for the sound of Fang Xuanling's clicking keyboard and the sound of the two people fiddling with their chips.

"These two pages total 196,481 yuan!" Fang Xuanling's voice suddenly sounded in the hall.

The hands of the two officials holding the brushes shook and they almost failed to grasp the brushes.

Of course, it is impossible to count everything in this competition in front of the palace, so I selected two pages.

And these two officials still haven't finished a quarter of the first page.

"Is this correct?" a member of the household department secretly asked.

"How do I know?" Dai Zhou replied angrily.

We were all officials in the same court, and although we had a good relationship with Fang Xuanling in private, we couldn't stand it when we failed so miserably in the arithmetic competition with the Ministry of Household officials that I had pushed for today.

Now the pressure was put on the other two officials. The two people who were originally complacent began to sweat, and big beads of sweat began to flow down their temples.

After a while, the clerk from the household department wiped his sweat with his sleeve and said with some trembling: "I...I'm done. It's exactly what the prime minister said."

Then the inner library was finished, and the three of them had the same answer, but the speed difference was too big.

"I wonder where you got this thing, Fang Xiang?" Dai Zhou asked with some jealousy.

Not to mention that ancient people were diligent in official duties, but few people who go to work are willing to work overtime.

This Ministry of Household Affairs is in charge of the country's money and food. Whenever there is a large amount of revenue and expenditure such as tax collection, it is always busy kicking the butt.

If there is something that can speed up work efficiency, who wouldn't want it? Is it really that the government office is my home, and I won't be happy if I work overtime?

"Please forgive me for being pretentious!" Fang Xuanling smiled mysteriously. Of course, he would not obscure Tang Ping's functions.

However, he felt that since Tang Ping had such great achievements, he naturally wanted everyone to see all his achievements in abacus and Arabic numerals, so that he could be rewarded based on his merits.

So Fang Xuanling went directly to the main hall and briefly explained the principles and usage of abacus, followed by the use of Arabic numerals.

Why does he calculate so quickly? Because if nothing else, it is just a statistical addition. You have to record it as you add it.

But if you use Chinese to record one thousand two thousand eight hundred yuan, how many strokes do you need to write? But what about Arabic numerals? 12800!

This efficiency has been improved by an unknown amount.

As soon as this thing was thrown out, the whole hall was in an uproar. I didn't expect it to be like this!

"Fang Xiang, who invented this thing?" Dai Zhou was the most excited. Wouldn't it be a waste if such a talent didn't come to his household department?

"Please recruit this person to the household department!"

"Look at what you said, Dai Shangshu, your Ministry of Household Affairs needs arithmetic talents, but our Ministry of Works doesn't need them?" Duan Lun, Shangshu of the Ministry of Works, also came out to speak: "If you can make such exquisite objects as abacus, I think it's better for me to work with you."

Ministry is the most suitable!"

Two ministers came out to grab people. The Ministry of Rites, the Ministry of Personnel and the Ministry of War also came out to join in the fun. After all, which department does not need arithmetic talents?

The list used for the competition just now was handed over by their Rites Department. If it weren't for the lack of math talents in the Rites Department, I would have done the calculations myself before forwarding it to the Household Department.

The Ministry of Personnel and the Ministry of War also have their own reasons.

Fang Xuanling didn't expect that before he said who he was, everyone was rushing to get him, but he wanted to keep this person in his family.

Although Tang Ping was the one teaching him arithmetic yesterday, many unintentional words made him feel that Tang Ping had extraordinary knowledge.

In his opinion, if such a person is well cultivated, he will become a talented person in the future, and it is most suitable for him to work under his own sect.

He took a step forward, raised his hands and said, "Your Majesty, this person..."

"This person……"

At this moment, my stomach started to feel turbulent again. If I didn't go to the toilet, I would be disloyal to you.

"Excuse me, veteran, to step back for a moment!"

This person has three urgent needs. Could it be different because the person he is dealing with is the emperor or the prime minister?
