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 happy to talk to the emperor, so she said: "The emperor is tired today, so he will inform outsiders that he will not have to attend the lecture." This was the first time since Zhu Yijun became an official. It can be seen that although Queen Mother Li is strict, she still longs for family affection and There is no difference between ordinary people. Zhu Yijun said with a smile, "I have a lot of free time now. Why don't I accompany my mother on a tour of the palace today? My mother's body is in the early stages of recovery, so she feels more relaxed when walking."
Empress Dowager Li happily agreed, and the two of them went to Empress Dowager Chen to greet her, had a meal, and then went to play together in the palace confinement. The two people came out of the back hall of Qianqing Palace and walked along the central axis of the Forbidden City to the Imperial Garden without sitting on the chariot. Because the emperor was not married, the palace was occupied by concubines left by Emperor Longqing. The mother and son did not want to be too alarmed, so they arranged a clear path in front of the people, so that everything they passed was quiet and there was no noise. In the middle of winter, a little snow covers the majestic palace. Although there are no flowers and trees in the palace, it is clean, spacious and handsome, and has a unique flavor. The two of them and their entourage all wore big sweaters and felt refreshed by the cold wind. Talk, talk, do whatever you want, and enjoy the rare family time. Just as they were swimming to a happy place, they saw Chief of Ceremony Zhangyin, Royal Horse Supervisor Fengyu and other palace officials coming hand in hand. It turned out that it was Feng Bao and others who had heard that the emperor's mother and son were visiting the palace, so why not join in the fun right in front of them?
Queen Mother Li was very kind to Feng Bao and saw him coming. He said: "You, the Supervisor of Ceremonies, have a lot of things to do. Why are you joining 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. He stood up and licked his face and said with a smile: "The Queen Mother is pitiful and pitiful for this servant! It's rare for the Queen Mother to do so. If you want to visit the palace with your Majesty, let your slaves wait for half a day." After saying that, he knelt down and picked up a tray and presented two objects. It was a wooden top inlaid with gold wire, and two small spinning tops were placed beside it. whip. Queen Mother Li's eyes lit up, she looked at the emperor and smiled 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. 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. In this place, a thin layer of ice formed within half a quarter of an hour. Another eunuch spread a layer of loess on the edge of the ice to prevent slipping. Feng Bao then directed the inner prison to erect bright yellow curtains and invited the Queen Mother and the Emperor to go in and change into non-slip boots.
Zhu Yijun never played with a top? In my previous life, I got tired of playing when I was a kid. I just saw that Queen Mother Li was interested, so I pretended not to know her just for fun. Although Empress Dowager Li had played it when she was a child, she had long forgotten how to play it. The young eunuch who had played with it first spun the top, and the mother and son went up and whipped it. After playing for a while, Zhu Yijun saw that the top fell over, so he picked it up and rolled it on his 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 struck it on the loess. He drew a simple diagram and said nothing while pretending to be deep in thought.
Seeing this, Empress Dowager Li smiled and said, "What can the emperor come up with?" Zhu Yijun waited for her to say this, and said with a smile: "Your Majesty, you have 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 little eunuch to bring over several square wooden boxes, a stick, a rope, and a weight. Empress Dowager Li entered Prince Yu's palace at the age of fifteen. It has been thirteen years now. She has rarely had a moment of relaxation. At this time, she put down her thoughts and had a childish attitude. When she saw the little emperor pretending to be old-fashioned, he just looked at things with a smile. he.
During a cup of tea, the little eunuch brought what the emperor wanted. Zhu Yijun placed the wooden stick horizontally, ordered two people to hold the two ends of the wooden stick, and first made a horizontal bar, about three feet above the ground. Tie the weight with a rope and tie it under the crossbar to form a "T" shape, like a pendulum. After testing the height, Zhu Yijun placed the square wooden box on the ice. Pulling up the weight, she said to Empress Dowager Li: "Mother, please look at this -" she released the weight, and the weight made a typical pendulum movement, hitting the wooden box squarely, hitting the wooden box from the ice surface to the other side. At the other end, it stops when it encounters loess. Then Zhu Yijun changed places, placed the wooden box on the ice-free ground, pulled the weight to the same height, and struck the wooden box. The wooden box stopped 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 roughness of the surface 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." Empress Dowager Li suddenly understood, but then asked: "But what's the point? 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 principle can either guide them to the right path, or increase the force that restrains them to prevent them from going on the wrong path. They must always make the best use of the situation and cannot use a frame to trap them."
This heresy was known to Newton in later generations, and the coffin boards would collapse. But I could hear Empress Dowager Li's eyes shining brightly and sighing repeatedly, and the eunuchs around her were also praising her. But the emperor continued to say: "These principles are of great use not only in governing the country, but also 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 -" He pulled the weight up and then released it, and the weight began to swing under the crossbar. "Huang'er used his own breathing to time and found that when the weight swings, when the swing amplitude is large, the swing is fast, and when the amplitude is getting smaller and smaller, the swing is slower. No matter how fast or slow it is, the swing time is the same for one week." Empress Dowager Li didn't believe it. Zhu Yijun did it several times, and Empress Dowager Li personally verified it before she was convinced. He smiled and said: "The emperor is too thoughtful, but how can this be used in the economy?"
Zhu Yijun lowered the horizontal bar again and tied a lot of ropes upwards. As soon as 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: "Mother, I don't dare to compete with the people for profit. However, the expenses in the palace 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 he 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 daily use." To reward people.”
Empress Dowager Li said displeased: "How unreasonable! Remember the late emperor said that the annual tribute tea from the local area is 14,000 jins. I calculated the expenses, including the sacrifices and rewards, and it is also 14,000 jins. The limit is one thousand jins. Where did these 80,000 jins come from? How are they used? You go find out and report it truthfully."
Feng Bao secretly complained in his heart, regretting that he came to the Queen Mother to join in the fun and earned a hot job. But he had no choice but to bow and accept.
Zhu Yijun smiled and said: "The queen mother does not need to ask her companion to check. There are many tricks in this palace. It is not good to look at it when you look it up." 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. If the money is obtained 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 will only cost 100,000, and the benefits derived from this clock will not be matched. It’s passed. If this happens, the people will surely praise it.”
Empress Dowager Li was originally the daughter of a small businessman. 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 childish, she was in a good mood today and asked, "If we find someone to do it, how much will it cost? How long will it take?"
When Zhu Yijun worked in tax collection and administration in his previous life, he worked very hard and went to 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 an escapement." He casually drew a few strokes on the ground and said: "If you install such a mechanism, This clock can be made 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. However, Feng Bao and other eunuchs were knowledgeable. At this time, they were dazzled and stunned by the emperor's intimidation. They didn't know how to flatter him. Feng Bao calmed down and said bluntly: "Your Majesty, once this thing comes on the market, there will be imitations, but the profits will be thin."
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. My lord, this is legitimately doing business for the emperor. It’s too late for the gentry from all over the country to thank God. Which leopard who has eaten the heart of a bear dares to imitate it? Xiaomin doesn't have the financial resources to imitate it even if he wants to.
A few people chatted and 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 coquettish, so he found an excuse to leave. Empress Dowager Li was thoughtful when she saw that the emperor's thinking was clear and there was no trace of childishness in his actions or words. He ordered his entourage to find the emperor's skilled craftsman and said no more. The two of them had exhausted their fun and returned to the palace together. When they arrived at the Empress Dowager's bedroom, Empress Dowager Li said, "The emperor will follow me in." Then she ordered everyone, "You guys wait outside."
Zhu Yijun followed Empress Dowager Li into the palace. Since the kangs in both palaces were laid out, Queen Mother Li sat on the kang and asked Zhu Yijun to come up as well. Zhu Yijun glanced around and said with a smile: "I will stand and my mother will sit down." He stood 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 it does not look like it 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 figured it out 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?"
Zhu Yijun asked and looked up at Queen Mother Li. Seeing that Queen Li was expressionless and her eyes showed no emotion, she pondered for a moment and replied: "I don't dare to deceive my mother. I do have some ideas that I want to show off. But after all, I am young, but -" Before he could finish speaking, he stood on tiptoes, walked quickly a few steps to a curtain in the palace, lifted it suddenly, and pulled out a small eunuch!
Queen Mother Li was startled and almost fell down. He saw that the eunuch, who was serving him in the palace, was named Xiao Dezi. He was caught off guard and was caught by the emperor. He was so frightened that he knelt on the ground, shaking his clothes and shaking.
Just as Empress Dowager Li was about to ask the emperor why he was like this, she suddenly reacted and turned pale with anger. The eyebrows and eyes stood up straight, and he said angrily: "I am talking to the emperor, but you, a slave, dare to eavesdrop! What do you want?!"
