Be a master through ancient times

"This arithmetic...cannot be deleted." Chu Ci pondered for a while, then said firmly.

Du Yu frowned: "I would like to hear the details."

"I heard that mathematics was not included in the imperial examinations before the founding of the Great Wei Dynasty. Why was this subject established later?" Chu Ci did not answer directly, but asked him a question.

Du Yu said: "The reason is that in the early days of the founding of the Great Wei Dynasty, a lot of waste was waiting to be done, and Gaozu ordered the officials to increase income and reduce expenditure, but at this time, there was a muddled official in a certain county who couldn't understand the account book and was not good at calculation. , was coaxed by the master to buy wood sold by several profiteers at high prices, resulting in a waste of tax revenue that year, and even sold the grain to pay off the debt. The next year coincided with a severe flood, and the people had no grain. However, the government couldn’t release any food, and in the end starvation was everywhere, and the people were displaced.”

"Gaozu was furious and executed these people directly. Then he said that if the parents and officials are not proficient in common things, how can they govern one side and make the people rich and the country strong? So he issued an imperial decree, saying that in the future the imperial examination must incorporate mathematics into it. Only This way, the tragedy will not happen again."

"But math...it's too obscure." Du Yu was a little embarrassed. It seems that he should be a scumbag when it comes to mathematics. They are all elders but not proficient. Therefore, in the next three years, the talents selected by the imperial court were far from enough to fill the vacancies in the imperial court. In desperation, Gaozu had to lower the difficulty. After three games, there is no math involved. In this way, the selected talents will fill the void."

Chu Ci listened with great interest. He originally only knew that mathematics was acquired in this dynasty, but he didn't know that there was such a reason.

"So, the reason why arithmetic is not in the college exam is not that arithmetic is not important, but because it is too difficult?"

Du Yu was taken aback by Chu Ci's words, and felt that what he said made sense. Wasn't that what he meant just now?

It's just... "However, over the years, arithmetic has not played any role. After learning the fourth volume, it is enough for everyone to understand the ledger, and will not be deceived by profiteers."

Chu Ci shook his head and muttered to himself: "Anaithology is very useful, but people haven't discovered its deep-seated role. Once it is discovered, the whole world will be changed."

Du Yu was listening, although he didn't understand some parts, but he didn't take it seriously. He felt that Chu Ci was a bit exaggerated. Isn't the function of arithmetic to prevent them from being fooled by those profiteers?Those who do business and business affairs are generally good at arithmetic, but scholars, farmers, businessmen, and businessmen are at the bottom of the list.

Chu Ci observed his expression and knew that it would be impossible to change his opinion in a short time. Just as he was thinking of a way to prove it another day, he suddenly thought of a story, so he asked Du Yu, "Old Du, what if Today a healthy servant is thrown into your farm, how much money do you need to give him a day? A month?"

Du Yu thought that Chu Ci wanted to test him, so he smiled and said: "When the old man checked the account book, it said that a healthy servant earns about 30 Wen a day, and [-] days a month, that is about [-] Wen."

"If the healthy servant proposes another way to pay the money, I wonder if my lord will agree?"

"what way?"

"He only needs one penny on the first day, two pennies on the second day, four pennies on the third day, and so on, sir?"

When Du Yuchu first heard it, he thought about how there could be such a stupid person. Wouldn't the monthly income be much less if it went on like this?But when he did the calculations casually, he broke out in a cold sweat.Every day, he doubled the amount of the previous day. On the tenth day, his money would be more than the original month. .

His smile froze on his face, and after a while, he said quietly: "Fortunately, A Ci, you never worked for others, otherwise, even a rich man like Zhao Wharf would not be able to last long."

Chu Ci knew that he was complaining that he was not authentic, so he smiled awkwardly, and then said: "Please don't be offended, Mr. Du, this junior just made a joke with you. However, this also shows to a certain extent that arithmetic is actually a It is an extensive and profound knowledge. We should not discard it after learning the level of the imperial examination. The six lines in the Book of Changes, Qin Tianjian can be familiar with astronomy and geography, which are inseparable from mathematics. Of course, the younger generation also It’s not that we want everyone to be proficient in arithmetic, but people who are proficient in arithmetic are essential. As a student in Zhangzhou Prefecture, the younger generation is able to have all kinds of talents in the area under their jurisdiction.”

Du Yu sighed slightly: "I also know that the science of arithmetic is profound and profound. I think I'm smart, but I can't understand it. It's also because of its profoundness, so what if I learn it? As the saying goes, outsiders can't understand it at all... ...Moreover, if you want to understand a subject, you will never be able to do it without devoting time and energy. Abandoning poetry and articles, and devoting all your energy to mathematics, how can they make a living after a few years? How should this group of people deal with the doubts of all living beings?"

Chu Ci suddenly found himself a little speechless, indeed, how could he let those students gamble their future to study mathematics before convincing the superiors to pay attention to mathematics?

All of this was still too simple for him.For him, mathematics is the foundation of all sciences, and qualitative changes can occur at a certain time. He hopes that one day, he can see the flowers of science and technology blooming all over the land of Wei. This is a spiritual need that will fill him with A sense of accomplishment and pride.But for those students, reading is nothing more than a means of survival for them - writing articles is the same as arithmetic.If you know that the return you get will be less than the investment, then who will do it?

Just like those modern scientific researchers, what supports them to invest in research day after day is not only ideals, but also bread.If there is not enough bread, where do they have the energy to study?Upper decision decided by the economic background.In modern times, the continuous flow of top talents to foreign countries is not just a manifestation of their pursuit of high returns?

Seeing his disheartened expression, Du Yu couldn't bear it.He knew that he had shattered a young man's vision for the future.No one can say that Chu Ci's idea is not good, but for this era, it is a bit too advanced, so that it seems a bit unrealistic.

He was very afraid that such a high-spirited young man like Chu Ci would be devastated after suffering setbacks, and when he was about to step forward to comfort him, he saw Chu Ci salute him.

"Mr. Du's words awakened the dreamer. This junior would like to thank you for your advice." Chu Ci sincerely thanked Du Yu. The collision of old and new ideas made him realize that his steps might have been too big.After coming to ancient times, his ideology was far ahead of this era. In the past, two gentlemen held the reins when he was studying, and when he exchanged letters with Kou Jing, Kou Jing would also mention him without a trace. Things, so that he can better adapt to this era.

In the past few months, due to the constant sea troubles, he had less contact with them, and the people around him respected and trusted him very much, which also made him "eager for quick success and quick benefits", delusional to become a fat man with one bite, eager to put his mind to sleep. All the advanced ideas in the book were copied over, but I forgot that everything had to be figured out slowly.

Du Yu was taken aback for a moment, and then burst out laughing: "It seems that the old man is overthinking, as long as you can figure it out. With your ability, you may still have the opportunity to promote those two books to Da Wei in the future." .”

"This is also the goal that the younger generation is striving for." Chu Ci also laughed, "Now, please don't hesitate to enlighten me, and help the younger generation delete the inappropriate parts of the previous books."

"Since you said that, Ah Ci, the old man won't refuse. Look here..." Du Yu opened one of the books, pointed to it and began to say.

Chu Ci took a step closer and listened carefully. He unconsciously grabbed the pen and paper on the table and recorded while listening.

……

ten days later

"Good news! Good news!"

A soldier ran towards the palace with a letter in his hand.

At this time, it was the time of the Great Dynasty, and after Tianhe Emperor listened to the transmission from the palace people, Long Yan was overjoyed and directly let the soldier go to the main hall.

"But the good news from the southwest?" Emperor Tianhe first thought of the southwest border. It had been reported several times there, and the city of Yuexi Kingdom was almost completely taken back.

The soldier shook his head and said, "My Majesty, this good news comes from Nanfu Province."

"Southern Fujian Province?" Emperor Tianhe was taken aback, "Is there an official war in Southern Fujian Province? Where are the people from the Ministry of War? Why haven't I heard about this?"

Tianhedi frowned. As an emperor, he didn't like the feeling that things were out of control.

Minister of the Ministry of War immediately stood up and said, "My Majesty, I am wronged! Marshal Zhu Wei of the Southern Fujian Navy did not submit the letter of invitation for war, and I don't know when they will start the war. What's more, the Guangdong and Guangxi navy sent for reinforcements also returned Before arriving in Southern Fujian, I really don't know what their good news is all about. Perhaps, Marshal Zhu wiped out some bandits, and he couldn't help passing the good news because he was happy for a while?"

Minister of the Ministry of War tearfully complained about his innocence, and quietly put on some eye drops, intending to show that Zhu Wei made a fuss out of a molehill and did it deliberately in order to win credit.In his opinion, the Nanfu Navy only has more than 500 people, and if it is really going to go to the battlefield, how can it be possible to report a good news?If the whole army is not wiped out, he is already considered powerful.

Sure enough, Tianhedi's complexion became unsightly.If Zhu Weizhen uses good news for a small matter, such a person who loves to make great achievements, then he will definitely not tolerate it.

"Send up the good news." A majestic voice sounded from above, and the soldier knelt on the ground and held up the letter with both hands, his head almost buried in the ground.

The palace man opened the letter and felt it, but found nothing suspicious, so he submitted it.

At the beginning, Tianhedi had a straight face, but after a while, his face changed from cloudy to sunny, and then he even laughed out loud, which made all the courtiers present feel confused.

Could it be that the Southern Fujian News is true?Zhu Wei led more than 500 naval forces to fight against the Japanese, and won the battle?Could it be that he is the reincarnation of God of War?A little sweat broke out on the forehead of Minister of the Ministry of War, these conjectures made him restless.

This letter was very thick, and Tianhedi read it for a long time before putting it down.He looked happily at the bewildered faces of the courtiers below, and said: "The Nanfu navy has won a sigh of relief for me this time. They even captured the general of the Japanese kingdom alive with very little damage, and captured 500 people. Many Japanese people ruined the plan of the Japanese Expeditionary Army to go east, and saved me from an innocent disaster, haha!"

"Congratulations, Your Majesty, your Majesty is a wise king, and you have loyal ministers and good generals to guard this great river and mountain for your Majesty!"

"Your Majesty is blessed with the same blessings as the heavens, so you don't have to worry about Yu Xiao's younger generation."

"..."

All of a sudden, rainbow farts came like a flood.

Tianhedi immersed himself for a while, and then said: "Guess who made this plan?"

There are different opinions below, and I don't know how they remembered the names of so many military attaches in Southern Fujian Province.

Emperor Tianhe shook his head mysteriously: "The guesses of all the lovers are wrong. I thought you would not be able to guess. Let me tell you, this person is Chu Ci!"
