While the two were talking, someone from the Supervisor of Ceremonies came to urge the emperor, saying that he was going to give a lecture at the Wenhua Hall. Queen Mother Li was so happy to talk to the emperor that she said: "The emperor is tired today, so he has informed outside that he will not give a lecture." This was the first time Zhu Yijun had had a baby since he was a child. It can be seen that although Empress Dowager Li is strict, her desire for family affection is no different from that of ordinary people. Zhu Yijun was self-righteous and said with a smile: "This is a lot of free time, why not go out with the empress today?" How's the palace? The Queen Mother's body has just begun to relax, and she feels a little relaxed when walking."
Empress Dowager Li happily agreed. The two of them went to Empress Dowager Chen to greet her, had a meal, and then started to play in the palace. The two came out of the back hall of Qianqing Palace, did not sit on the chariot, and walked along the central axis of the Forbidden City. We walked to the Imperial Garden. Since the emperor was not yet married, all the concubines who lived in the palace were the concubines left by Emperor Longqing. The mother and son did not want to be too disturbed, so they arranged a clean path in front of them, and everything they passed was quiet and without any noise. In the middle of winter, a little thin snow covered the majestic palace. Although there were no flowers and trees in the palace, it was clean, spacious and handsome, and had a unique flavor. The two people and their entourage all wore big sweaters and were blown away by the cold wind. They all felt refreshed after blowing the wind. They talked, walked as they pleased, and enjoyed the rare family time. Just as they were swimming to a happy place, they saw the palm print of the ceremonial supervisor, Feng Yu, the royal horse supervisor, and other palace officials came hand in hand. Come on, it turns out that it was Feng Bao and others who heard that the emperor's mother and son were visiting the palace, why didn't they just join in the fun right in front of them?
Empress Dowager Li was very kind to Feng Bao. When she saw him coming, she said: "You, the ceremonial supervisor, have many things to do. Why do you come to join in the fun in front of our mother and son? Why don't you go and do your business!" Feng Bao saluted and paid homage, stood up and licked She smiled and said: "The Queen Mother has pity on this servant! It's rare that the Queen Mother and the Emperor are willing to visit the palace, so this servant has to wait for half a day." After saying that, he knelt down and picked up a tray and presented two objects. There was a golden wooden top with two small whips beside it. Empress Dowager Li's eyes lit up and she looked at the emperor, smiling without saying a word.
Zhu Yijun's mind changed and he asked with a smile: "What is this?" When Queen Mother Li asked, she laughed and said: "Poor my son, I have never played with such a thing. This is called an ice top. It can be whipped on the ice with a whip." It turns beautifully."
Zhu Yijun laughed and said: "Where is the ice? There is no river in the palace? Do you have to go to Xiyuan for this?" Feng Bao laughed and said: "Back to the emperor, there is a river in the palace, over there at Wuying Hall. ——" Hearing Feng Bao continue to say: "The weather is very cold this year, so the servants have brought water." After that, he ordered the young eunuchs to find a spacious place and pour the water in the copper basin into a ten-square-meter area. It took only half a quarter of an hour for a thin layer of ice to form in the place. The inmate also spread a layer of loess on the edge of the ice to prevent slipping. Feng Bao also directed the inmate to erect a bright yellow curtain and invite the Queen Mother. The emperor and I went in and changed into non-slip boots.
Zhu Yijun never played with a spinning top? In his previous life, he was tired of playing with it when he was a child. He just pretended not to know the Empress Dowager to have fun when he saw that Empress Dowager Li was interested. Although Empress Dowager Li had played with it when she was a child, she had long forgotten how to play it. The little eunuch who had played it had After spinning the top, mother and son went up and whipped it. After playing for a while, Zhu Yijun saw that the top had fallen over, so he picked it up and rolled it on the whip. With a flick of his wrist, the top started spinning again, but Queen Mother Li, Feng Bao and others were stunned. Just when Feng Bao was about to flatter him, he saw Zhu Yijun picked up the top and said with a smile: "This top won't fall over when it spins, but it has its own reason. Today, we must follow the teachings of the sages and follow the rules." After saying that, he picked up the whip and put it on the ground. He drew a simple diagram on the loess and pretended to be deep in thought without saying a word.
Seeing this, Empress Dowager Li smiled and said: "What can the emperor find out?" Zhu Yijun waited for her to say this, and said with a smile: "Your Majesty has gained a lot from searching for things these days. I don't mind it, please tell me about it today."
After saying that, he asked the young eunuch to bring a few square wooden boxes, a stick, a rope, and a weight. Empress Dowager Li entered the palace at the age of fifteen and entered Prince Yu's palace. It has been thirteen years now, and she has rarely felt relaxed.
At this time, I let go of my thoughts and had a childish mentality. I saw the little emperor pretending to be old-fashioned and picking up things, and just smiled at him.
During a cup of tea, the young eunuch brought what the emperor wanted. Zhu Yijun placed the wooden stick horizontally and ordered two people to hold the two ends of the wooden stick. First, they made a horizontal bar, about three feet above the ground, and tied it with a rope.
The weight was tied under the crossbar and turned into a "T" shape, like a pendulum. After testing the height, Zhu Yijun placed the square wooden box on the ice. He pulled up the weight and said to Empress Dowager Li: "Mother, please look at this."
——" Release the weight, and the weight made a typical pendulum motion, hitting the wooden box squarely, hitting the wooden box from one end of the ice to the other, and stopping when it encountered loess. Then Zhu Yijun changed
Place the wooden box on the ice-free ground, pull the weight to the same height, and hit the wooden box. The wooden box will stop after walking a short distance.
Empress Dowager Li said blankly: "The ice is very slippery, so this wooden box can go farther. What did the emperor mean?"
Zhu Yijun smiled and said: "Mother Mingjian: If there is a flat surface in this world that is ten thousand times more slippery than this ice - doesn't this wooden box have to go on forever?"
Queen Mother Li said: "What's the matter? How can there be such ice in this world?"
Zhu Yijun glanced around and saw that everyone including Feng Bao was confused. He smiled and said: "The queen thought about it more carefully. Since ancient times, people have said that all things are stationary. If you want to
If you want them to move, you have to give it an external force, push it, or pull it, but you don't think deeply about it. This thing is meant to keep moving, but the force of friction restrains it, and this
The force of friction is related to the surface roughness of the object, such as ice, loess, and the ground."
Queen Mother Li continued to be confused: "So what? What does this have to do with the top not falling?"
Zhu Yijun smiled and explained: "Look, Queen Mother, the top is spinning on the ice because the tip of the top cannot withstand the strong friction force." Empress Dowager Li suddenly understood, but then asked: "But does this mean anything?"
What’s the use?”
Zhu Yijun smiled and said: "I have figured out the truth that all things are meant to move. When I apply it to governing the country, I realize that it is impossible for all things in this world to obey the emperor's orders quietly. The emperor must find them and move them.
The truth is to guide them to the right path, or to increase the force that restrains them to prevent them from going on the wrong path. We must always make the best use of the situation and not use a frame to trap it."
This heresy was known to Newton in later generations, and the coffin boards were about to collapse. But he heard Empress Dowager Li's eyes flashing with brilliance, and she sighed repeatedly, and the eunuchs around her also praised her endlessly. But the emperor continued to say: "These truths are clear.
, Regardless of running the country, it is also of great use in running the world." After saying that, he asked the two eunuchs to raise the horizontal bar and said to the Queen Mother Li: "The Queen Mother, look at it -" He pulled up the weight and let it go.
The horizontal bar began to swing, "Huang'er used his own breathing to time it, and found that when the weight swings, when the swing amplitude is large, it swings faster, and when the amplitude becomes smaller and smaller, it swings slowly, no matter how fast or slow, the swing time is the same." Li
The Queen Mother didn't believe it, so Zhu Yijun did it several times, and Queen Mother Li personally verified it, and then she was convinced. She smiled and said: "The emperor is too thoughtful, but how can this be used in the economy?"
Zhu Yijun lowered the crossbar again and tied the rope up a lot. When he loosened the weight, the swing of the weight accelerated significantly.
"I studied this weight and found that the time it takes to swing in one round is related to the length of the rope, and as long as the ropes are of the same length, the swing time remains unchanged. Using this principle, if a device is designed that can be used to measure time, it should be faster than now.
The time leakage is much more accurate, which is used in economics. Queen mother, please look at it -" I used a wooden stick to draw the shape of a later clock on the loess, and also drew the shape of a pendulum, and said with a smile: "Queen mother,
I think the harem is short of funds, and I can't ask for it from the outside world. If I find some skilled craftsmen to design this clock, set it with some jewelry and jade, and market it all over the world, the profit will be worth tens of dollars.
Ten thousand."
Empress Dowager Li laughed and said: "This idea is wrong. How can the emperor's family compete with the people for profit? This cannot be done."
Zhu Yijun Surong replied: "Queen mother, I don't dare to compete with the people for profit. However, the palace expenses are taken from the people. I checked these days and found that only tea, last year's tribute tea was
There are more than 80,000 kilograms -" Empress Dowager Li opened her mouth wide and couldn't close it: "How can the palace use this much?"
After hearing this, Feng Bao felt sweat on his forehead and bowed and said: "Queen Mother, it is indeed as the emperor said. However, it is not all used in the palace. Guanglu Temple, Hubu, and Nanjing all use some, either for sacrifices or for use."
To reward people."
Empress Dowager Li said displeased: "How unreasonable! I remember that the late emperor said that the annual tribute tea from the local area is 14,000 jins. The Ai family calculates the expenses. This sacrifice and reward are included, and it is also 10,000 jins."
The limit is four thousand kilograms. Where did these eighty thousand kilograms come from? How are they used? You go and find out, and report it truthfully."
Feng Bao secretly complained in his heart, regretting that he came to join in the fun of the Queen Mother and got a hot job. But he had no choice but to accept the offer.
Zhu Yijun smiled and said: "The Queen Mother does not need to ask her companion to check. There are many tricks in this palace. Even if you look it up, it doesn't look good." Feng Bao breathed a sigh of relief and heard the emperor say again: "I checked the agricultural books and found out that this collection
The time for tea is the busy farming season, so picking tea has also missed the farming season. I estimate that the people have been suffering from tribute tea for a long time. This clock can only be bought by rich people. If this clock is sold, it will be sold from now on.
After getting the money from the rich, there is no need to let the people pay tribute to the tea in the future. The palace will buy it directly. Even if the palace spends 20,000 jins of all the tea, it only costs 100,000.
It has passed. If this happens, the people will surely praise it."
Empress Dowager Li was originally the daughter of a small business family. She had been exposed to the business since she was a child and did not reject the business of merchants. Although she felt that Zhu Yijun was making baby talk, she was in a good mood today and asked: "If you find someone to do it, how much does it cost?"
How much? How long?”
When Zhu Yijun worked in tax collection and administration in his previous life, he worked very hard and visited many companies. He carefully recalled the memory of the clock handicraft processing factory he visited, and said with a smile: "I have also thought about a mechanism recently, called the escapement." casually.
He drew a few strokes on the ground and said: "If you install such a mechanism and make this clock, you can get it in ten months. If it can be manufactured on a large scale, the eunuchs in various places should open imperial shops to sell this clock exclusively."
Empress Dowager Li, a woman in the palace, didn't know much about the principle of studying things to gain knowledge, and she didn't know the difficulties in the design of this clock. After listening to the emperor's words, she had no other feeling except that he was smart. But Feng Bao and other eunuchs were.
The knowledgeable person was already dazzled by this time. He was so stunned by the emperor that he didn't know how to flatter him. Feng Bao calmed down and said bluntly: "Your Majesty, once this thing comes to the market, there will be
The counterfeit ones are less profitable."
After hearing this, Zhu Yijun raised his eyebrows on his little face and said: "I personally designed something with the words "Made in the House" engraved on it. Who dares to imitate it?" Feng Bao thought about it. The eunuchs guarding all over the country eat people without spitting out their bones.
Lord, this is a legitimate business for the emperor. The gentry from all over the country have no time to thank God. Who dares to imitate the leopard after eating the bear's heart? The common people do not have the financial resources to imitate even if they want to.
A few people joked for a while, but Feng Bao was afraid of the emperor, fearing that he would say something inappropriate again that would make him look embarrassed, so he found an excuse to leave. Empress Dowager Li saw that the emperor had clear thinking and no trace of childishness in his actions and words.
If he was thoughtful, he ordered his entourage to find the emperor's clever machine and said no more. The two of them had finished their fun and returned to the palace together. When they arrived at the Empress Dowager's bedroom, Empress Dowager Li said: "The emperor came in with the Ai family.
"He then ordered everyone: "You guys wait outside."
Zhu Yijun followed Empress Dowager Li into the palace. Because the kangs in both palaces were set up, Empress Dowager Li sat on the kang and asked Zhu Yijun to come up too. Zhu Yijun glanced around and said with a smile: "I am standing, and the Queen Mother is sitting."
Standing by the kang.
Empress Dowager Li pondered for a moment and asked: "Today the emperor said that this 'investigation of things' is very ingenious and does not seem to be something that can be taught by old gentlemen who have read the Four Books. But it was taught by the teachers in the dream?"
Zhu Yijun replied: "I don't remember this, I just thought of it naturally." This kind of lying requires skill. Zhu Yijun's previous lies were very well made. There was not much to explain, but they could give rise to countless possibilities, which made Li
The Queen Mother made up her mind on her own.
Empress Dowager Li pondered again and said: "The emperor talked to his mother about tribute tea, people's livelihood and other situations today, but he wants to personally govern?"
When Zhu Yijun asked, he raised his head and glanced at Empress Dowager Li. Seeing that Empress Dowager Li was expressionless and her eyes showed no emotion, he pondered for a moment and replied: "I don't dare to deceive the Queen Mother. I do have some ideas and want to show them off."
.But I am young after all, but—" Before he could finish speaking, he stood on tiptoes, walked quickly a few steps to a curtain in the palace, and suddenly lifted it, pulling out a small eunuch!
Queen Mother Li was startled and almost fell down. When she saw that the eunuch was Xiao Dezi, who was serving her in the palace, he was caught off guard and caught by the emperor. She was so frightened that she knelt on the ground, shaking her clothes and trembling.
Just as Empress Dowager Li was about to ask the emperor why he was like this, she suddenly reacted and turned pale with anger. Her eyebrows stood up and she said angrily: "I am talking to the emperor, and you, a slave, dare to eavesdrop! What do you want?
