At the beginning of the civil castle, the Ming God of War was a little panicked

Chapter 189 The Almighty Talent Yu Qian
After listening to it, Yu Qian looked confused, and subconsciously said, "What kind of...question?"

Zhu Qizhen smiled lightly, and said: "The first question, the pheasant and the rabbit in the same cage... Oh, no, it should be called the pheasant and the rabbit in the same cage!"

"Pheasant...isn't it a pheasant?" Yu Qian scratched his head, puzzled, "Since it's arithmetic, what's the difference between a pheasant and a chicken?"

"You're right, there's no difference, the chicken just fucks!"

For some reason, when chickens are mentioned, people can't help but think of a line of lyrics...

Zhu Qizhen shook his head, threw this strange idea out of his head, then pondered for a moment, and said the topic: "Today, there are chickens and rabbits in the same cage, with 35 heads on the top and 94 feet on the bottom. geometry?"

Chickens and rabbits in the same cage are just the simplest linear equation in two variables. However, this problem is not modern. It was first recorded in "Sun Tzu's Mathematical Classics". At that time, who could solve this problem , is very capable.

It will definitely be called a magical calculation, comparable to the existence of Zhuge Liang.

After listening to the questions, Yu Qian fell into deep thought and did not respond for a long time.

Zhu Qizhen seemed to have expected this result a long time ago, so he said, "Actually, this question..."

"Back to the emperor, there are 23 chickens and [-] rabbits in the cage!"

This time it's Zhu Qizhen's turn to be in a daze, true or false, you can also solve equations?

Seeing that Zhu Qizhen didn't answer, Yu Qian asked, "Your Majesty, did you make a mistake?"

"Wait a minute!"

Zhu Qizhen picked up a pen and did a simple calculation on the paper. He confirmed that the answer was 23 and twelve, nothing wrong!

"Tell me, how do you calculate?"

Yu Qian nodded, and replied: "Set 35 heads on the top, and 94 feet on the bottom. Half of the feet, you get 47, subtract more from the less, and then order it, the upper three divides the lower three, the upper five divides the lower five, and the lower one divides the upper." One, if there are two at the bottom, divide the two at the top, and you will get it. I have a second solution, put the head on the top, put the feet on the bottom, half the feet, divide the feet with the head, and divide the head with the feet, and you will get it."

Zhu Qizhen was stunned. In a short period of time, Yu Qian used two methods to solve the problem, especially the second solution...how did he calculate it?

Why does it sound like Mathematical Olympiad, no, I am the time traveler, logically speaking, I should hang and beat you!
Now the situation... it seems like you are the time traveler...

"You did a good job, now listen to the second question!"

Zhu Qizhen paced back and forth a few steps, thinking to himself, this time I have to make it harder for you.

"It's still arithmetic. Today there are things that don't know how to count them. When counting three or three, there is two left, when counting five or five, there is three left, and when counting seven or seven, there is two left. Ask the object geometry?"

This principle is called "I don't know the number of things", and it also comes from "Sun Tzu's Suan Jing". It is said that there are some items, and I don't know how many there are. If there are 3 items, there will be 3 more items if there are 2 items and 5 items. How many of these items are there?

In later generations, this problem is also very simple, that is, to find a natural number that has a remainder of 3 when divided by 2, 5 when divided by 3, and 7 when divided by 2. As long as you have studied in junior high school, you can easily calculate this number. The minimum number is 23.

Sure enough, this question stumped Yu Qian. He frowned, closed his eyes, and remained silent for a long time like an old monk in meditation.

Zhu Qizhen secretly said in his heart, I still don't believe it, and if you answer it again, I will ask you about calculus!
After a full stick of incense, Yu Qian finally opened his eyes and said, "23!"

Zhu Qizhen was stunned again, did you really answer the question?
Could it be that I really need to take out calculus to calm you down?
But... I didn't learn calculus myself...

"Tell me, how do you calculate it?"

Yu Qian let out a long breath, and then said: "If you count three or three, you have two left, set 140; if you count five or five, you have three left, set 63; if you count seven or seven, you have two left, set thirty. Combine them, and you get 230 Three, subtract it from 210, and you will get it. If you count three to three and one is left, set it to seventy; If it is more than one hundred and six, subtract it from one hundred and five, and you will get it."

Zhu Qizhen's face was already a little ugly. After thinking about it, he seemed to have almost forgotten the knowledge of calculus...

"Okay, let's listen to the third question. Today there is a wall five feet thick, and two rats cross each other. The rat is one foot a day, and the mouse is also one foot. The rat doubles every day, and the mouse half a day. Question: When will we meet again? How much do you wear?"

Although this question is not as good as calculus, it is also very difficult.

There is a five-foot-thick wall, and two mice are facing each other to make a hole. The big mouse can dig a foot on the first day, and so can the little mouse.Every day after that, the speed of the big mouse was double that of the previous day, and that of the small mouse was half that of the previous day.Ask how many days the wall can be opened, and how much the big mouse and the little mouse dug respectively.

This is an encounter problem of variable speed movement. The difficulty lies in the variable speed. The mathematical methods of the ancients were limited, and there was no such tool as the algebraic function today. I don’t believe you can still answer it!

Even if you use the most stupid way to deduce it day by day, it will not work.

On the first day, the big mouse hit 1 foot, the little mouse hit 1 foot, a total of 2 feet, and 3 feet left;
On the second day, the big mouse hit 2 feet, and the little mouse hit 0.5 feet. This day, a total of 2.5 feet was hit, and in two days, a total of 4.5 feet was hit, leaving 0.5 feet;
On the third day, it is reasonable to say that the big mouse hits 4 feet and the small mouse hits 0.25 feet, but now there is only 0.5 feet left to get through, so it will definitely be able to get through on the third day.

The crux of the problem is that the third day is not complete. This 0.5 feet needs to be disassembled. This is the most difficult part. How do you dismantle it?
However, what Yu Qian did next made his jaw drop again.

I saw Yu Qian took a pen and paper and listed out a series of calculations. It seemed that this question was not as difficult as imagined.

Zhu Qizhen couldn't help but leaned forward to take a look, but found that... he couldn't understand!

It's like a system of equations, and it's like a matrix. In short, it's very mysterious...

This time, Yu Qian didn't spend much time and gave the answer quickly.

Zhu Qizhen stared blankly for a while, then asked helplessly: "In this world, is there no problem that can stop you?"

"Why did your majesty say that? I just read some books other than the Four Books and Five Classics when I was studying, and I know a thing or two about these arithmetic problems."

"Tell me, how did you solve the last question?"

Yu Qian pointed to the numbers on the paper and said: "Return to the emperor, this method is called the surplus-deficiency technique, which specializes in solving all kinds of loss-profit problems..."

After Zhu Qizhen listened carefully, he suddenly discovered that this surplus-deficiency technique seems to have the same effect as the equation.

The two are very similar, but not exactly the same. For a while, it is impossible to tell which one is better.

Suddenly, he became happy in his heart. He has been worrying about a problem for a long time. It will be difficult to develop natural science in this era, and he will encounter various resistances. Even if he is the emperor and has supreme power, he cannot Change it if you say it.

But now it seems that this is not the case at all.

Taking the most basic mathematics as an example, the ancients clearly did research, and the research was very in-depth, but Zhu Yuanzhang stipulated that the imperial examination only examines the Four Books and Five Classics, and scholars will not care about things other than the Four Books and Five Classics. All the treasures left by man were buried.

Especially in the Qing Dynasty, the imperial examination system was more stringent, and there was a large-scale literary prison. Except for the Four Books and Five Classics, any book may become a banned book, which made the knowledge of scholars narrower, and the situation of useless scholars became more obvious.

When the strong ships and guns of the West slammed the gates of the Qing Dynasty, the world knew what the outside world was like.

Therefore, since that era, people with lofty ideals began to study the West in all aspects. They learned the advanced ideas of the Westerners, learned the science and technology of the Westerners, and learned everything about the Westerners, even their religious beliefs. At the same time, they will The things left by my ancestors are regarded as dross, and I can't wait to throw them all away.

The root of this problem is, of course, the Qing Dynasty's seclusion and lack of progress. However, going forward, the responsibility of the Ming Dynasty is not small.

In any era, you must not stand still, otherwise, you will be eliminated by the era, you will fall behind, and you will be beaten!

Therefore, the reform of Daming must be carried out!

Even if Lao Tzu's position as emperor is unstable, this change is imperative!

"Yu Qian, thank you, you have helped me a lot!"

Yu Qian was at a loss. Are these three questions important?

Zhu Qizhen continued: "Now I don't want to say too much, in a word, Daming must make changes, this will be a war, Yu Qian, I need you to help me win this battle, do you have confidence? "

Yu Qian immediately said: "I would like to obey the imperial decree!"

Zhu Qizhen shook his head and said: "This is not a matter of compliance. I don't want to force you. You must know the importance and necessity of this change. If Daming doesn't make changes, one day sooner or later, people will step on you." Underfoot, I don't want to see this day, do you understand?"

Yu Qian nodded his head half-understood, and said, "I...seem to understand!"

"Okay, I'll leave this reform plan to you. After you go down, you can perfect it. Our monarchs and ministers are going to have a fucking fight. If we win, we will live forever, and Ming will be brilliant for hundreds of years! If you lose, you and I will both become sinners in the writings of future historians, and will remain infamous forever. More importantly, Ming Dynasty will go to the road of decline. Therefore, we have no way out in this battle, we can only win, not lose!"

Seeing Zhu Qizhen's serious face, Yu Qian wanted to ask another question, but he didn't dare to ask.

"Just say what you have to say, I don't treat you as an outsider, so don't meet outsiders in front of me!"

Zhu Qizhen really has no reservations about Qian.

Not to mention the sins committed in the previous life, just from the talent of governing the country, Yu Qian's role cannot be replaced by ordinary people.

"Then... I would like to ask you one more question..."

Yu Qian asked cautiously: "The emperor understands what the emperor means, but why is the emperor so urgent? The Northern Yuan Dynasty has been pacified, and the border of our Ming Dynasty has expanded to the Onon River. The Japanese pirates on the southeast coast have just been pacified. I don't have the strength to fight against Daming. I, Daming, have neither internal nor external troubles. If we want to implement the new policy, we should do it slowly. I don't know what the emperor is worried about?"

"You still don't understand!"

Zhu Qizhen shook his head slowly, and said: "You should know how difficult it is to implement the New Deal. In fact, I have planned for a long time, but I have not been able to implement it because it affects the interests of too many people. Fortunately, this time The treason case in Nanjing gave me an opportunity, if I don’t take the opportunity to make changes, it will be even more difficult to implement in the future.”

Yu Qian nodded, and asked again: "The minister is worried that if the New Deal is enforced, if it is serious, there may be a murder case..."

"If I want to make a change, I am not afraid of killing people. Moreover, I have not forced those gentry to a dead end. Under the New Deal, they still have an absolute advantage. They have money and land, and they can open workshops, or In business, all in all, as long as you are willing to work hard, you will get no less reward than you are now. What I want to get rid of are those who hold a lot of land in their hands, do nothing all day long, and only squeeze the people. The scum of the country!"

Hearing this, Yu Qian finally understood why Zhu Qizhen was so eager to make changes.

If you want the country to be rich and the people strong, you must mobilize all the people. It is not a good thing for the country to accumulate wealth by suppressing the people.

You do business and open workshops. These behaviors not only earn money, but also drive employment, and the lives of the people can be better. Therefore, the emperor's plan encourages everyone to go out and move.

If these changes can be implemented, then Daming will be completely different, it will be a brand new world!

"Please rest assured, Your Majesty, my minister Yu Qian issued a military order. If I still have breath, the New Deal will be carried out to the end!"

Zhu Qizhen nodded in satisfaction, and said: "With you here, the pressure on me will be much less. Since we want to change, we will start with the people's basic necessities of life, measure the land, and spread it out in Nanjing and its surrounding areas first. Set an example, and then promote the whole country!"

Yu Qian thought for a while, and then said: "Your Majesty, forgive me, Jin Yiwei has arrested too many people, and the number of officials in the Six Departments of Nanjing has decreased by [-]%, and even half of the people in some yamen have disappeared, and there is no one... The work is not easy to carry out. I suggest that these vacancies should be filled first."

Zhu Qizhen shook his head and said, "What more is there to make up for? The Six Ministries of Nanjing have all been withdrawn. Don't want them anymore!"

"what?"

Yu Qian was stunned again, what's going on?
"I said that the Six Ministries of Nanjing will be abolished directly, the Forbidden City will be retained, Yingtian Mansion will be retained, and all other yamen will be removed. As for those officials... just to make up for the vacancies of local officials, I have already drawn up an edict and will issue it tomorrow."

Yu Qian's face was very shocked. Don't you want to go to Nanjing?

Say no to no more?
As we all know, Ming Dynasty had two capitals, one in Nanjing and one in Beijing.

After Taizong Emperor Zhu Di moved the capital, Nanjing City has been kept as an accompanying capital, exercising part of the power of the imperial court. Its biggest role is that if one day, the city of Beijing cannot be defended, the emperor can withdraw to Nanjing. There is a complete set of imperial court here The team can be put into operation immediately.

In history, Emperor Chongzhen could have moved south in the face of King Chuang's army, but he finally chose to hang himself on the southeast branch...
