Chapter 104: Wedding (Part )
Let’s get straight to the point without further ado and continue the discussion between Li Yi and Liu Ruyun from last time.
Li Yi agreed with Ruyun's words because he knew the significance of mathematics. Mathematics can be said to be the foundation of various sciences. He continued, "Sister Ruyun is right. However, the significance of mathematics is not only closely related to life, but some of its branches can even affect the trend of the world. Let me give you a simple example."
Li Yi looked at Lu Shu and asked, "To build a strong crossbow, the key to determining the range and lethality of the crossbow is the elastic coefficient of the crossbow bow. We need to use mathematics to determine the elastic coefficient and choose the material with the strongest elastic coefficient to make the crossbow bow. Of course, in addition to the crossbow bow, the string must also be selected by comparing the strength coefficients of various materials, combined with geometric and mechanical calculations, so that we can build the most cost-effective crossbow."
The crowd had never heard of terms like elastic coefficient and strength coefficient, and they were all confused, but Lu Shu could roughly understand some of them, so he asked: "Xiu Yuan, what are the elastic coefficient and strength coefficient you are talking about? What are geometric and mechanical calculations?"
Li Yi explained: "When we press the arrow against the crossbow string, the crossbow will be pulled and deformed. The ratio of this deformation to the pressure it receives is the elastic coefficient. Similarly, the strength coefficient is the ratio of the maximum pressure that the crossbow string can withstand to the maximum deformation. Doesn't Minister Lu know this? The selection of materials for the crossbow and crossbow string can be calculated, which can save a lot of costs?"
Lu Shu said with embarrassment: "When making a new crossbow, we usually make a test product directly, then keep trying, improving and exploring, and then constantly adjusting, and finally get the finished product. If we follow the method of repairing the edge, we can indeed save a lot of trouble in material selection. But how do you calculate the two coefficients you mentioned?"
Li Yi is a liberal arts student and is not good at mathematics, but he knows a little bit of simple high school mathematics knowledge. Moreover, in this era, he has the final say on how to define the deformation variable.
So he said, "This problem is not very simple. Just calculate the area of the two semi-arcs of the crossbow. Using the sector area formula, the area is equal to the arc length multiplied by the radius divided by two!"
Liu Ruyun asked: "How do you calculate the arc length?"
Li Yi slapped his forehead and laughed, "The stupid way is to use a rope to measure, the smart way is to calculate, the arc length is equal to the circumference of the circle multiplied by the central angle divided by three hundred and sixty."
These mathematical formulas shocked everyone. They didn't understand them at all. The only person who could follow Li Yi's train of thought was Liu Ruyun. She looked at Li Yi and asked, "How did you come up with these algorithms?"
Li Yi scratched his head. He couldn't say it was nine years of compulsory education, so he said, "These are all basic common sense. Don't you know, for example, the circumference of a circle is the diameter multiplied by π, the area of a circle is π multiplied by the square of the radius, and the area formula of a triangle is the base times the height divided by two."
Liu Ruyun looked at Li Yi and asked, "Formula? What is pi?" Li Yi replied, "π is the ratio of the circumference of a circle to its diameter. I remember 3., but I can't remember the rest. It's an irrational number."
Liu Ruyun narrowed her eyes and looked at Li Yi and said, "You are so good at mathematics?"
Li Yi quickly waved his hands and said, "I'm not good at it, I just know a little bit!"
Liu Ruyun asked, "Really? Then let me test you. One hundred buns for one hundred monks. Three senior monks will not fight over one bun. Three junior monks will share one bun. How many buns do the senior and junior monks have?"
Li Yi's jaw almost dropped to the ground. He thought: This is a math problem at the level of an elementary school student. Is there anything wrong with it? Sister Ruyun, you didn't stump Tao Zhongwen with this kind of question, did you? Then Tao Zhongwen must be too bad!
Li Yi immediately gave the answer: "How simple is that? The senior monks are twenty-five, and the junior monks are seventy-five."
Liu Ruyun smiled faintly and asked again: "Oh? It's easy, then let me ask a difficult question. Use a rope to measure the well. The rope is folded three times, leaving four feet outside the well. The rope is folded four times, leaving one foot. How long is the rope? How deep is the well?"
After asking this question, Liu Ruyun looked at Tao Zhongwen with a smug look on her face. Li Yi shook his head and sighed, "Sister Ruyun, it's better not to ask this kind of question. Ask something more difficult!"
Liu Ruyun was surprised and asked, "You figured it out now?"
Li Yi thought, this is a linear equation with one variable, do I need to calculate it? Oh!
So she answered, "The rope is thirty-six feet long, the well is eight feet deep, Sister Ruyun..."
Liu Ruyun smiled and said, "Great, I actually met someone who knows how to do this. Come on! Listen to this question: Three sparrows and four swallows weigh a pound in total. The sparrows are heavy and the swallows are light. If we swap one of them, they will weigh the same. How much do the sparrows and swallows weigh?"
Li Yi shook his head and said, "Okay, the linear equation with one variable is changed to a linear equation with two variables. Is this difficult?"
Lu Shu asked: "Xiu Yuan, what is a linear equation?"
Li Yi waved his hand and said, "Forget it. I can't explain it clearly. I'll just tell you the result. The sparrow weighs three taels and two cents, and the swallow weighs one tael and six cents."
Liu Ruyun was surprised and said, "Li Yi, you are really good. I didn't expect you to calculate so quickly. Okay, then I will ask another question."
Li Yi quickly begged for mercy: "Sister Ruyun, please let me go. Today is my wedding day. If you insist on competing with me, then Li Yi will admit defeat now. How about that?"
Liu Ruyun curled her lips and said, "Okay, okay, I'll let you go today and we can compete again another day!"
Li Yi heard that Sister Ruyun was going to challenge him, so how could he do that? He had to think of a way. He thought for a moment and then said, "Sister Ruyun, how about this? I'll give you a problem and you can solve it. When you solve it, I'll promise to compete with you. How about that?"
Liu Ruyun became interested and said, "You ask the questions first!"
Li Yi laughed and said, "There is a wall ten feet thick. Two rats are facing each other and digging a hole. The big rat digs one foot a day, and the small rat also digs one foot a day. The big rat doubles its length every day, and the small rat halves its length every day. Let me ask when they meet and how many feet of hole each of them digs?"
Liu Ruyun said without hesitation: "It's not difficult to meet in four days. Let's each wear a few feet..."
Li Yi smiled and said, "Sister Ruyun, you have to calculate the time and length more accurately. I'll tell you after you've calculated it clearly."
Sister Ruyun immediately fell into deep thought. This question is not difficult. If you have learned limit operations, it will be very simple. However, it is very troublesome because you may have to calculate to many decimal places if you want to be precise. For this era, it is an unknown area. Li Yi just wants to use this method to delay time.
Liu Ruyun sat down slowly. Seeing her take the table, Fang Zhuo, Chen Liang and two girls Ruolan and Hua Yu also sat down. At this point, all the guests were present. Li Yi bowed again at each table and then went to look for Dugu Yu. At this time, the maids brought wine and food and placed them on the table.
A moment later Dugu Yu came to the stage, bowed with a smile and said: "Today I am honored to witness with you the wedding of the most talented man in our Great Wei. I am entrusted by Shiyu to be the master of ceremonies. This is the first time I have accepted this task. If there is anything wrong, please bear with me!" After saying that, he bowed deeply.
Nangong Qi said loudly: "Brother Yu, I think you are unwilling to be the master of ceremonies! I guess you don't want to take the job of master of ceremonies, but rather the job of groom!"
There was a burst of laughter from the audience, and Dugu Yu sighed, "My parents gave me life, but Brother Qi knows me best! To be honest, I really want to be the groom! What a pity! I don't have the ability of Xiu Yuan, otherwise, how could he have gotten his turn!"
There was another round of laughter from the audience. Dugu Yu put down his hands and said with a smile, "To be honest, I am not happy with Xiu Yuan's getting such a good deal. How can he marry three beautiful ladies at once? I, Dugu Yu, will be the first one to disagree. So as the MC today, I will not let him get his beautiful lady so easily! Let's cooperate with me and make things difficult for him together, how about that?"
Nangong Qi clapped his hands and cheered: "Okay! We will definitely cooperate!"
Minister Kong muttered quietly: "What is this? This is not in accordance with etiquette!"
Tao Zhongwen laughed and scolded, "Kong idiot, the young people are just having fun, why are you making such sarcastic remarks here! I only know your broken etiquette, you nerd!"
Lu Shu said with a smile, "Minister Kong, what Master Tao said is absolutely right. New people should use new methods, and young people should always act like young people. Besides, Xiu Yuan has no parents to worship, and no relatives to help him. It's all the fate he formed with those girls. You should put aside your etiquette and just watch! See what new tricks the young people today can come up with!"
Kong Xiu shook his head helplessly and said with a smile: "Okay, okay, then I'll see what these young people can do nowadays."
Dugu Yu on the stage straightened his clothes and said solemnly, "The auspicious time has arrived. I declare the wedding officially open. First, please welcome the groom, the most talented scholar in Wei, the Minister of Rites and Music, Li Yi Li Xiuyuan!"
Li Yi came to the stage amid the music, bowed to everyone, and then said to Dugu Yu: "Brother Yu, we are brothers, but you just said you wanted to embarrass me. Isn't that a bit unfair!"
Dugu Yu said sternly, "Don't try to be too close to me. This is something that Miss Shiyu asked me to do. Today, you are no longer my brother! If I have offended you, I will apologize today!"
There was a burst of laughter from the audience, and Dugu Yu said, "Next, let us welcome the first bride, she is Miss Bai Ling, who amazed everyone with her heavenly music and promoted Confucianism with her singing!"
At this time, the band started playing the song "Rain Butterfly". Bai Ling, wearing a pink dress, walked slowly onto the stage to the sound of the music, singing as she walked. There were no special effects or purple air. The two of them just performed the song with their most sincere feelings. From meeting to falling in love, from separation to reunion, although they did not experience much together, this feeling was the first throbbing in their lives. This is the rare thing. How many lovers complain about separation, how many true love breaks reality, and how many first loves can bear fruit?
After the song was over, the two of them embraced and looked at each other affectionately. Dugu Yu interrupted them at an inappropriate time and said, "That's enough, if you want to take her home, go ahead! Don't you see what the occasion is and how many people are watching? Aren't you ashamed?"
When Bai Ling heard this, her face immediately turned red, and she quickly stood up and lowered her head in shame. Li Yi turned around and looked at Dugu Yu, knowing that this kid was going to do something bad!
Just as he thought, Dugu Yu said, "I've said it before, Li Yuefu married three ladies at once. This is something that ordinary people wouldn't even dare to think about. I'm the first one who can't stand it, so I won't let you pass easily! Then I'll ask you a question. If you can answer it and satisfy Miss Bailing, then you'll pass this test!"
Li Yi looked at Bai Ling, then at Dugu Yu and said, "Ask!"
Dugu Yu sneered, "Okay, then let me ask you, Li Yuefu had made an engagement with Miss Bailing when he was in Qing'an City, so why did he flirt with Miss Shiyu when he arrived in Shangjing! Have you forgotten that Bailing in Qing'an City misses you day and night?"
As soon as this question came out, Li Yi's face changed, and everyone in the audience was also shocked. How could such a sensitive question be asked in public? You know, the difficulty coefficient of this question is as high as 10.0!
When Li Yi returned to Qing'an City, he had to use rogue means to get away with it. In this situation, Dugu Yu raised this issue, which was equivalent to ruining the place. Li Yi was so angry that he wanted to beat Dugu Yu to death. He brought up this issue!
Seeing Dugu Yu's smug look and Bailing standing beside him in silence, Li Yi had a rough idea in his mind. If he didn't answer this question well today, it would leave hidden dangers in the future!
So he laughed and said, "Brother Yu, your question is very unreasonable. It was you and Brother Qi who forced me to go to the Exiled Immortal Tower!"
Nangong Qi said loudly: "Xiuyuan, this is your dishonesty! It is true that we forced you to go to the Exiled Immortal Tower, but we asked you to help us enter the Moon Palace, and we did not force you to have a romantic relationship with Miss Shiyu! Don't push this crime onto us!"
Li Yi was already cursing in his heart. These two people had obviously planned to make things difficult for him! He glanced at Nangong Qi and Dugu Yu coldly, secretly thinking about how to break the deadlock.
Dugu Yu smiled and said, "Brother Qi is right. I hope Li Yuefu can find the reason from himself and give us and Miss Bailing a satisfactory answer!"
Li Yi took a deep breath and said solemnly: "Since ancient times, love between men and women is a common human nature. A gentleman is lustful but not promiscuous, and he loves money but gets it in a proper way. Indeed, you are a beautiful woman, but you have been buried in the dust. You have lost your country and father, and you have suffered national hatred and family hatred. These great tragedies in the world have all happened to a woman like Shiyu. How can I turn a blind eye to them!
As a Confucianist, I have a noble character. If I don't help her out of the fire, how can I stand up? If I don't save her from the sea of suffering, it will be unacceptable! After this incident, Li Yi knew that it was difficult to solve the sufferings of the world with one person's strength, so he made a wish that he would never enter a brothel again in this life, and do his best to help more people who are suffering like Shiyu with practical actions! "
Such big and empty words are the best answer at this time, because there is nothing wrong with them, every word makes sense, but they don't say anything, so you still have to be able to speak official language and clichés.
Dugu Yu looked at Li Yi and didn't know how to answer for a moment. After thinking for a while, he looked at Bailing and asked, "Miss Bailing, are you satisfied with this answer?"
This question was not originally thought up by Bailing, but by Shiyu. Bailing would certainly not embarrass Li Yi, as she had long since accepted the reality, and now that she and Shiyu were sisters, she naturally nodded in approval.
Dugu Yu shook his head and said, "Well, I guess you've passed this level! Let's both toast to the guests here." Accompanied by the cheerful music of Landlord, Li Yi and Bailing walked to each table to toast.
When they arrived at Liu Ruyun's table, Liu Ruyun, who was still doing mental arithmetic, saw Li Yi and Bailing coming to toast him, so he withdrew his thoughts, raised his glass and said to Bailing: "I told you a long time ago that this kid is not an easy person to deal with. Now you know! He spends a lot of money, you have to keep a close eye on him!" Everyone at the table laughed for a while.
Fortunately, there were only six tables so the process was quick and not much alcohol was consumed. After the toast, Li Yi and Bailing returned to the stage. Dugu Yu smiled and said, "Sister Bailing, do you have anything to say to Xiuyuan at this moment?"
Bai Ling smiled faintly and said: "Flowers may bloom again, but people can never be young again. When I say goodbye to you, I hope we will be together until we are old."
Dugu Yu smiled and said, "Li Lefu, Miss Bailing wants to grow old with you! Don't you have anything to say?"
Li Yi smiled and said, "I wish I could rely on your heart and stay together till we grow old together."
Dugu Yu quickly covered his cheek and said, "Ouch, it's sour, so sour! My teeth can't stand it!"
Everyone in the audience burst into laughter. Dugu Yu said seriously, "I say, Li Lefu, was Sister Bailing deceived by you?"
Dugu Yu looked at Bai Ling, who shook her head quickly. Dugu Yu smiled and said, "Oh, but I know how he tricked Miss Shiyu into his hands! He finished writing four poems and songs, and Shiyu fell for him on the spot! That day, I saw what a truly talented and romantic man is!
However, the second level today is set by Miss Shiyu herself. But before setting the question, Li Yuefu must write a love poem. Writing a poem is definitely not a problem for you, the great talent Li. So in order to increase the difficulty, this poem must be a masterpiece of all time. Are you sure about Xiuyuan?"
Li Yi smiled faintly and began to recite:
once having seen the best, the rest is not worthwhile looking.
I am too lazy to look back at the flowers, partly because I am practicing Taoism and partly because I miss you.
I want to know you forever, and I only ask that we can follow each other in this life.
If one day the mountains were gone, the rivers dried up, and the winter thunder roared,
In the midsummer when it rains and snows, heaven and earth merge. I dare not break up with you even though we have been destined to be together!
As soon as Li Yi finished speaking, purple air gathered. He controlled the purple air above the ship and then gave Bailing a look. The latter understood and turned to wink at the musicians. The music started playing. It was the song "Dang" by Power Train.
Bailing: Ah ah ah ah ah
Li Yi: When the mountain has no edges
When the river stops flowing
When time stops and day and night become inseparable
When everything in the world becomes nothing
I still can't break up with you
I can't break up with you
Your gentleness is my greatest hope in this life
Bai Ling: When the sun no longer rises
When the stars stop moving
When spring, summer, autumn and winter no longer change
When all the flowers and trees withered
I still can't separate from you
Can't separate from you
Your smile is my greatest attachment in this life
Let us live a carefree life with the company of the world
Riding horses and galloping to share the prosperity of the world
Sing to the wine and express the joy in your heart
Seize the youth with vigor and vitality
Ah Ah Ah Ah Ah Ah (Li Yi holds Bai Ling's hand and slowly raises it above his head.
Ah, ah, ah, ah! The two of them opened their hands, and the long river formed by the purple air was divided into
Ah, ah, ah, ah! Two streams flow into the palms of the two people.)
Ah Ah Ah (Shiyu steps onto the stage)
