I sell anxiety to court officials in Daxia

Former Prime Minister Dou is a Spartan.

He just returned to the court! You did this to me, making an eighty-year-old man take a math test. Is that polite?

Xu Yanmiao, I let you play with Zhuo Yu for nothing these two days!

I wanted to give it to you, but now you are dreaming!

Prime Minister Dou rushed into the palace angrily: "Your Majesty! Do I, an old man who is about to die, have to take the mathematics exam?"

The old emperor covered his chest: "Ouch! Ouch!"

Prime Minister Dou paused: "Your Majesty, what's wrong with you?"

The old emperor gasped: "My heart hurts a little. Uncle, help me to the couch, I'll lie down for a while."

Prime Minister Dou hurried forward and helped him to the couch. He was too embarrassed to mention mathematics again. After a little hesitation, he asked: "Do you need to call the director of the Imperial Hospital?"

The old emperor took a breath and waved his hand: "No, I'll be fine after lying down for a while."

Prime Minister Dou sat aside worriedly.

The old emperor closed his eyes and rested, as if he was really resting.

On the other side.

Xu Yanmiao was still busy in the palace perfecting the details of mathematics with the prince.

The prince looked at Xu Yanmiao with admiration after writing two lines: "You dare to do such a thing that offends the public, Xu Lang, you are really a newborn ox that is not afraid of tigers. If you were not from the Ministry of Examination, I would have suspected that you were increasing the power of the Ministry of Examination."

- The Ministry of Personnel's Ministry of Examination is now the only department that can laugh. They are in charge of the annual official assessment. Xu Yanmiao's proposal completely hits their heart.

Xu Yanmiao added a few words in the memorial about "officials' age and adjustment of the difficulty of mathematics examinations". Hearing this, the prince said seriously, "We don't ask them to learn how to use the method of cutting a circle to calculate the side length of a regular polygon with 12,288 polygons and the area of ​​a polygon with 24,576 polygons inscribed in a circle. We just need them to have a basic knowledge of mathematics, master how to take square roots and cube roots, and understand probability. If they don't understand these, aren't they gambling with the conscience of the officials?"

The prince's mouth twitched, "That's true."

- Strictly speaking, what Xu Yanmiao meant by "calculating the side length of a regular polygon with 12,288 polygons and the area of ​​a polygon with 24,576 polygons inscribed in a circle" should be called: calculating pi to seven decimal places. The prince just wanted to say that if this is really the exam, then even if you kill them, they still can't pass it.

Xu Yanmiao: "Your Highness, think about it. Officials have a basic knowledge of mathematics so that they won't be deceived by their subordinates using false accounts, right?"

Xu Yanmiao: "I've read a sentence before: your eyes will confuse you, your experience will mislead you, your intuition will deceive you, your relatives, subordinates, friends, and classmates will all try to deceive you, but not mathematics."

The prince joked: "Because if you don't know mathematics, you don't know it?"

Xu Yanmiao said seriously: "Yes. If you don't know mathematics, you don't know it."

The prince was stunned.

Xu Yanmiao: "In other words, if you want to know whether a number is correct or wrong, and whether it is possible, you must use mathematics to observe and verify. It is completely objective and not affected by any subjective factors. I think Your Highness should have experienced this before. No matter how you look at a person, he is a good person. You would never think that he is actually corrupt, taking bribes, and bullying men and women behind his back, right? It's not like that. If you think about it, you won't think of checking it. This is the 'subjective influence'. But if you see that the numbers in the account book he submitted are wrong, you will know that he is suspected of falsifying accounts to deceive his superiors. This is the 'objective influence'. "

Xu Yanmiao: "I think that an official must try his best to eliminate subjective influences."

From beginning to end, the prince's mind was chaotic, and he didn't know what emotions to differentiate. Until this moment, his thoughts barely swam out of this chaos and stared at Xu Yanmiao quietly.

'Ah. '

He seemed to realize it belatedly, and then reacted:

They were all talking about Xu Yanmiao's naivety in the ways of the world, and were worried that he couldn't understand the hidden meaning of other people's words, and laughed that he always inadvertently pitted the court, but... they always unconsciously forgot that Xu Yanmiao had the most unique insights, the longest vision, and the most thorough vision in the world.

- He always showed that he was beyond the cognition of this era.

The prince smiled faintly: "You said..." Right.

[Speaking of this, it would be great if the emperor also needed to take an arithmetic test. ]

The prince was out of his mind: No, no, no! This is not right!

- Because, he really has the possibility of becoming the emperor ()

- He really has a cow! (Shocking sound)

In the distant Wuying Palace, Emperor Tiantong, who was originally lying on the couch with his eyes closed to rest his mind, suddenly faced the malice of the world and almost couldn't pretend to be sick.

Feeling the worry and thoughtful look in the eyes of his brother-in-law next to him, the emperor continued to close his eyes, determined not to open them even if he was suffocating.

It's impossible to let him learn arithmetic! Absolutely impossible!

- But the prince can be arranged. After all, it was said before that the princes needed to be assessed, and the prince, as the crown prince, did not belong to them.

It only took a breath of time for the old emperor to make a prompt decision: Push the crown prince out! Let Xu Yanmo stop paying attention to him, an old man who is almost seventy years old.

The crown prince is also a king, and learning the crown prince is equivalent to paving the way for himself to become an emperor!

After happily working out this equation in his head, the old emperor opened his eyes and prepared to call for help.

[After all, if you don't learn, it's hard to guarantee that your subordinates won't make false accounts, right?]

[Even if the other party is indeed trustworthy at the beginning, can you really resist greed in the long run? After all, not only the emperor's son doesn't know how to count, but the emperor himself doesn't know how to count either.]

Xu Yanmiao played a joke that only he knew.

But the old emperor didn't know he was playing a joke and almost jumped up from the couch.

You don't know how to count! Your whole family doesn't know how to count! Xu Yanmiao, don't spread rumors!

Even the prince was particularly emotional: "Beep--" "Beep--" "You are the one who beeps--"

I don't know what these inner thoughts have silenced.

Anyway, Xu Yanmiao himself sat very obediently. Judging from his appearance, who would have thought that he dared to slander the emperor in his heart.

[Alas, it's a pity that I still have to live. I can only make some superficial remarks about this matter. I dare not speak directly.]

The old emperor was silent for a moment, his chest heaving violently, and then he exhaled heavily and said in a clear voice: "You, fart!"

When will the little bastard die!

The old emperor let out his anger and sorted out his emotions. He frowned and recalled his previous thoughts.

"Tsk."

It seems that he really needs to learn to count.

Prime Minister Dou hesitated: "Your Majesty, I have this..."

The old emperor: "Shut up! Learn it all from me! I have learned it all, do you still want to learn it?"

Prime Minister Dou looked gloomy, and when he lowered his head, he tried to suppress the smile on his face.

——When things cannot be changed, seeing that the emperor has also fallen into the pit, he feels much more balanced in his heart.

＊

The prince calmed himself down and tried to keep smiling: "Xu Lang is right, mathematics is indeed very important - it's a pity that such important mathematics has not been truly valued until now."

Xu Yanmiao smiled: "It's not too late now."

[It's not too late for foreigners to rely on strong ships and powerful guns to open the door to China. ]

...What?

In the East Palace, the prince suddenly clenched the pen.

In the Wuying Palace, the face of the former Prime Minister Dou suddenly changed.

And the old emperor sat up from the soft couch with bloodshot eyes.

There was a shocking wave hitting the government offices everywhere, as if it made hundreds of people terrified, thousands of people bloodshot, and tens of thousands of people shattered.

What does "relying on strong ships and powerful guns to open the door to China" mean? !

Is that what they think it means? !

This matter had been kept in the hearts of the rulers and ministers of Daxia for three days. When the crown prince "happened" to meet Xu Yanmiao, he asked casually, "Xu Yanmiao, what do you think of overseas countries?"

Xu Yanmiao was stunned for a moment: "What do you mean?"

The crown prince pinched the armrest with his hands, and veins bulged where his sleeves were covered.

He suppressed his anxiety and chose his words carefully: "After the general and Marquis Luo went to sea, the court began to manage overseas, connecting islands with ships and fortresses. But I have been worried, what if we encounter overseas countries that are hostile to Daxia?"

Xu Yanmiao subconsciously checked the system and flipped through the gossip in the West: [Fortunately, there is no need to worry in the next fifty years. Foreign countries have not yet started colonial expansion, the Renaissance has just begun, and the remaining darkness of the Middle Ages still shrouds them. Now Daxia has begun to pay attention to commerce and mathematics, and will slowly pay attention to industry. There is still time. ]

Do we still need to pay attention to industry?

Prime Minister Dou Qian rushed to the table at a speed that was not suitable for an 80-year-old man, tore off a piece of paper and took a pen, thought for a while, and wrote down a sentence as if he was just practicing calligraphy on a whim, which contained the word "industry".

Meanwhile, in the East Palace, no one knew how the prince had seduced people, but Xu Yanmiao's thoughts came in waves.

[Ah? Population? Who has nothing to do to calculate the population... But maybe Daxia has a larger population? It seems to be twice the population of the country with the largest population...]

Prime Minister Dou Qian's solemn expression improved a little, and as if he had a sudden idea, he wrote two verses of hidden-head poetry with the word "Ren Lu". It means "population", and as if he was grading his own poem, he marked the word "first" after the poem.

——In this way, even if Xu Yanmiao saw it, he would not understand the meaning.

[Army? Then this is even more impossible to understand! After the generals went to sea, they did not fight with those powerful countries. At most, they fought some small countries - that was a crushing posture. After all, at this point in time, China's firearms and military combat power are definitely among the best. 】

Former Prime Minister Dou took note of the army's situation in his mind, intending to remember it later and shuffle the order.

Many military officers breathed a sigh of relief.

It's okay to be among the best, at least they can still fight now - but how did China become so corrupt in the future that it was actually overtaken by foreigners?

This question is destined to have no answer, and only Xu Yanmiao's voice can be heard: [Copper ore? How is it possible to know the copper ore reserves! This is not the era of big data... However, I think high school geography mentioned that Chile was a copper mining kingdom. Where is Chile now? Ah! I remember! The southwestern part of the new continent discovered by Xie Xianhou and his people! Now South America was discovered by China first, and the copper mine should be discovered in the future... right? 】

Prime Minister Dou Qian also quickly memorized this in his mind, but was afraid that he would make a mistake when he recalled it in the future, so he took out a handwritten travel journal from the bookcase and folded a corner at the lower left corner as if casually.

[Do you also want to inquire about shipbuilding technology? Anyway, it seems that it is shipbuilding technology that can travel around the world. 】

Prime Minister Dou Qian lowered his eyelids slightly.

He knew what this represented, representing all kinds of resources in the world, and other countries can also obtain them.

——Those people also have ships!

Even the resources on the new continent discovered by Daxia may not belong only to Daxia.

[What level of technology have other countries reached? ]

[Let me see...]

[Using peat fertilizer to improve the soil should be counted. And grass root mud to preserve the fertility of the soil. That counts too. ]

[The discovery that plowing the field three times can increase the harvest by two to three times should also be counted. ]

[The use of the three-field crop rotation system has increased the harvest by one-half to two-thirds. ]

[The water mill is a steam engine in the Middle Ages. In addition to water mills, there are also wind mills. ]

[Oh, right! And let horses replace cows to plow the land! Many areas are using it! ]

"What! Impossible! This is absolutely impossible!!!"

The agricultural officials threw their rationality, prudence and objectivity out of their minds, and were shocked and crazy.

Horse plowing is indeed better than ox plowing. The work that a horse can do on arable land is equivalent to that of three to four oxen, but at the same time, the cost expenditure is three to four times.

If a country is popular with horse plowing, it must prove that its national strength is strong, the arable land is large, and the grain produced is large. Otherwise, it cannot afford the cost of horse plowing.

The countries outside... are really strong. They can't be self-satisfied anymore!

Anxiety spread among the monarchs and ministers of Daxia. They were eager to do something. They woke up from their dreams for a long time, and their hair fell out in clumps.

Xu Yanmo was shocked: "Is it so painful to study mathematics?"
