After taking over the sword spirit branch of the Xuanyuan Sword, kneeling before the All Saints Tower, and adding thirty-seven sticks of incense to the incense burner in front of the All Saints Tower, Zhang Yue walked to the front of the All Saints Tower, and someone took a hat and a A pair of shoes. The hat is round, symbolizing the sky, and the shoes are square, symbolizing the earth. This hat and a pair of shoes symbolize the sky above the head and the earth under the feet. A passionate man should stand upright. "Zhang Yue! Zhang Yue! Zhang Yue!" After Zhang Yue put on the round hat and square shoes, the thousands of people gathered in front of the Ten Thousand Saints Tower burst into cheers at the same time, and countless people shouted this name at the same time. "Just now, Senior Brother Zhang Yue saidSenior Brother Zhang Yue is the thirty-seventh master of the Transcendent Realm in our Shenghua City. So, there are a total of thirty-seven masters of the Transcendent Realm in our Shenghua City?" At this moment, Yunyang was a little curious. Shi Fangzhuo nodded: "That's true. In the past hundred years in our Shenghua City, a total of 192 transcendent realm masters have appeared. However, except for these 37 people, the other 155 people have already They died in the process of protecting our Shenghua City Every one of these people is a good man, every one of them is a passionate man who stands up to the heaven and earth." Yunyang felt sad in his heart: "My father is also here. Among fifteen people, right?" "Of course your father is the biggest hero in our Shenghua City." In a hundred years, a total of 155 transcendent realm masters were killed. One hundred and fifty-five powerful masters of the extraordinary realm died. "This Shenghua City seems to be stable, but in fact it is full of dangers" Yun Yang sighed secretly in his heart, "Doudou also disappeared for no reason, and there is still no trace I can never be so idle in the future. My father, whom I have never met, is a hero, my master is a hero, and my senior brothers and sisters are all heroes. How can I, Yunyang, be a person who only knows how to enjoy peace of mind under the protection of their wings" Today's worship ceremony deeply touched Yunyang's heart. Yunyang seemed to see one after another Transcendent Realm masters rushing to the enemy's lines for the sake of the health of Shenghua City, or fighting bloody battles among the monster beasts until death. Even if they died, they would become heroic spirits and rest forever. In the Ten Thousand Saints Tower, the city is still being silently guarded Yunyang has also seen how hard the people of Shenghua City who are still alive have devoted themselves to protecting their homeland Yunyang knows that every pair of eyes hungry for knowledge Behind it, there is a heart praying to make myself stronger so that I can protect my homeland. Everyone in Shenghua City is struggling, and everyone is contributing their own strength. It is precisely because of the unity of these thousands of people that Shenghua City has always stood erect on this eastern land and has never collapsed. "In that casehow can I be willing to just be a moth?!" Yunyang gritted his teeth secretly. The grand and simple worship ceremony has ended at this moment, but the banquet has not yet begun. After Zhang Yue left the stage, countless pairs of eyes focused on Yunyang. At this moment, the minds of countless people who have thought hard and still have nothing to gain are full of question marks: "How can we calculate the size of the ancestral star based on those known conditions?" Except Yunyang, no one Know the answer to this question. Today is the day when Yunyang announces the final answer. Yunyang gathered his thoughts for a moment, stood up, walked to the crowd, and stood on the stage. The experience of facing many primary and secondary school students in popular science classes in his previous life gave Yunyang a good psychological quality. Even when facing so many people, Yunyang still did not feel nervous. "Mr. Five! Please tell me how to calculate the size of the ancestral star! I have not rested for several days in a row to solve this problem. I have been thinking hard for several days but still got nothing, so I asked Mr. Five to answer our doubts! "The student no longer expects to find out the answer and become his disciple. The student just wants to know how to calculate it!" "Mr. Five! Please announce the answer quickly!" Seeing Yunyang standing on the stage, the crowd below immediately The noise started, and waves of noise came and went. Yunyang sighed slightly in his heart, "No one has found out the answer" "Don't be anxious, everyone." Yunyang said loudly, and at the same time pressed his hands down, everyone The noise immediately disappeared, and countless pairs of eyes stared at Yunyang closely. "Before I announce the final answer I need to confirm it." Yunyang said slowly, "Is it true that no one can know the final correct answer? If anyone can find out the answer, he can become Senior Brother's Personal disciple." There was silence below, no one spoke.?. Yunyang glanced at the crowd below, and found a dejected Zhao Wei near the front. The big man like an iron tower looked like a defeated rooster at this moment. Yunyang felt slightly surprised in his heart, and looked to the side again, and saw a middle-aged man whose features were vaguely similar to Zhao Jia staring at Zhao Wei angrily. Yunyang understood it as soon as his heart moved, but he felt it was slightly funny. That middle-aged man was obviously Zhao Jia's father, and Zhao Wei did not get the final answer to the question from him yesterday. Zhao Jia was also unable to pass the assessment and become Zhao Ke's direct disciple. Probably because of this, then Only a middle-aged man would treat Zhao Wei coldly. "This will offend my future father-in-law in advance, Zhao Heilian, your future will be worrying." Yunyang felt a little gloating in his heart, "But since you are also an honest person and agreed to one of my conditions, I'll give you a hand later, so what if I offend my father-in-law? As long as the girl is devoted to you, it doesn't matter to my father-in-law." Several thoughts quickly passed through my mind, but no one came to answer me. Yang then continued: "In that case let me tell you the final answer." "The circumference of the ancestral star is 40,000 kilometers, and the radius is about 6,400 kilometers." "The calculation process is Knowing that the length of the iron rod is two meters and the shortest shadow length is 1.6 decimeters, the vertex angle can be calculated through trigonometric functions to be 4.5 degrees. 4.5 degrees is one eighty-eighth of 360 degrees, and Shenghua City The distance to the measurement location is one thousand miles. Multiply one thousand miles by eighty, and you can get the circumference of the ancestral star The result is 80,000 miles, 40,000 kilometers. Once you know the circumference, divide it by pi. You can get the diameter, and then divide it by two to get the radius This number is about 6,400 kilometers. " Yunyang spread his hands. After Yunyang said these words, everyone fell silent. Many people rolled their eyes, obviously doing rapid mental calculations, double-checking the results Yunyang said. Of course, there can be no mistakes in this mathematical calculation process. Those people also came to the same result as Yunyang after very simple calculations. Buta moment later, someone started making noise. "Why do we need to calculate it like this? The vertex angle is indeed 4.5 degrees, and 4.5 degrees is indeed one-eighth of 360 degrees. But, what does it mean to multiply a thousand miles by eighty? Where does it come from? It can be concluded that the vertex angle of the triangle, 4.5 degrees, is the arc angle of the ancestral star between Shenghua City and the measurement location? " It can be said that this question is the key to all problems. Before Yunyang announced the final answer, those who worked hard on this problem could find this calculation process even if they combined it randomly. However, there was a very fatal problem, that is, they did not know why they had to calculate in this way, and they did not know why they had to do it. Multiply one thousand miles by eighty. "I don't know why I need to multiply one thousand miles by eighty, so naturally I don't know the final answer." Because Yunyang's requirements are very clear. He must not only tell his answer, but also his calculation process, and also explain why he uses this process. He must explain everything thoroughly before he is finally passed. tested. Now, countless pairs of eyes with questions and doubts were once again projected on Yunyang. Next to him, Feng Wei, the dean of the Academy of Arts, who was sitting quietly, and a group of old men from Guanxing Pavilion standing behind him, also looked at Yunyang slightly nervously. The other half, Zhao Ke, Meng Qianhui, Zhang Yue, and Shi Fangzhuo, also looked at Yunyang slightly nervously. The reason is very simple. According to their speculation, if Yunyang, who was originally ignorant and incompetent, suddenly has the ability to calculate the size of the ancestral star, then Yunyang is undoubtedly the one who was given by God, and the person who was given by God will have a great influence on Shenghua City. It is of extremely important significance. Whether Yunyang can finally explain his conclusions clearly and justify himself is related to many things, and it is not just as simple as answering a question. But Yunyang, who is in the center of the stage, obviously has no awareness of this. Hearing that many people questioned his own conclusion, Yun Yang rolled his eyes and said in a slightly resentful tone: "Everyone who has taken my class, please stand up and stand next to me." " Oh?" Many people squeezed out from the crowd and stood next to Yunyang with questions on their heads. "Don't say that I taught you when you get out, you really embarrass me." Yunyang scolded these students severely, "You have learned so many things I taught you? Recall it carefully, Have I ever taught you about parallel lines? Have you ever taught me about the principle of equal angles? "But what is the difference between these things and why we need to multiply one thousand miles by eighty times?" Does it matter" one student asked angrily. "It's like a wooden head!" Yunyang cried out in anger: "You, reach out your hand"??¡± The student stretched out his hand, and Yunyang took a piece of wood from somewhere and hit the palm of the student¡¯s hand hard: ¡°I¡¯ve told you so many things don¡¯t you know how to apply them?¡± Damn it" He gave the student a harsh lesson until the student almost buried his head in his crotch in shame. Yun Yang finally stopped. Then he scolded the student with some incomprehension and shouted loudly. Shouting: ¡°Bring me the blackboard and chalk! Today I will explain to you why we need to multiply one thousand miles by eighty! A bunch of idiots, they have received so many zakat from me, but they still act like they haven¡¯t learned anything! " A group of students were silent, not daring to say a word. Although they didn't understand why, they probably knew that they had made a stupid mistake, which is why they made Mr. Wu so angry. The crowd below also stopped making noise. Seeing that Yunyang was so confident, he couldn't help but start thinking about where he had made a mistake and couldn't find the answer. Someone quickly brought the blackboard and chalk. Yunyang stood in front of the blackboard, still a little confused. He scolded in displeasure: "Watch carefully! If you still don¡¯t understand this time, just don¡¯t come to my class in the future! " It was quiet before the Ten Thousand Saints Tower. No one spoke, and I don't know how many eyes were focused on the blackboard in front of Yunyang. Even Zhao Ke narrowed his eyes slightly, and Feng Wei leaned forward unconsciously. Yunyang leaned forward and first drew a big ball on the blackboard and said, "This is the ancestral star. " Then Yunyang drew a few straight lines outside the big ball, "These are the sun's rays. Attention, attention! Different sun rays are parallel to each other, parallel! " There is one line between these different solar rays that is directly connected to the center of the circle. Yunyang highlighted this line: "This is why I chose to measure the size of the ancestral star on the summer solstice. The reason is because on the summer solstice, the sun's rays shine directly on us, that is to say, the sun's rays are perpendicular to the ground! If you don¡¯t believe me, you can go take a look at the deep well in Shenghua City on the summer solstice and see if the sunlight can directly shine to the bottom of the well on this day, but not on other days? " "So what? "Feng Wei frowned in a low voice and said, "This is indeed the case on the summer solstice, but there seems to be nothing strange" "Then look at this point a thousand miles away. On the summer solstice, the sun shines directly on Shenghua City, perpendicular to the ground. Things can have no shadow, but that is not the case a thousand miles away. It must have a shadow. If there is a shadow, then if the length of the iron rod and the length of the shadow are known, then its vertex angle can be calculated through trigonometric functions. Everyone must be able to do this step, so I won't go into details. Now Look, everyone, the sun's rays shining directly on Shenghua City , and the rays of the sun a thousand miles away are also parallel, right? Since they are parallel, it can be represented by such a graphic" Yunyang said, and he drew a few more times on the blackboard, extended the other sun ray, and then used a straight line to connect the center point of the circle and the straight line. The intersection point with the earth ¡°Parallel lines, pay attention to the knowledge of parallel lines! "Yun Yang tapped the chalk on the blackboard and shouted loudly. Feng Wei suddenly fell to the ground with a whoop, bringing the bench down with a crash. Several professors nearby rushed to help him, but Feng Wei himself Gulu got up, his hair was messy and he didn't even bother to straighten it, he ran all the way to Yunyang, yelling at the top of his lungs: "That's it, that's it! really! The vertex angle of 4.5 degrees is the arc angle between Shenghua City and the measurement location! Indeed! Simply multiply one thousand miles by eighty to get the circumference of the ancestral star! " Yunyang nodded with satisfaction and said to himself: "It seems that this old man's reaction is quite fast. " At this moment, the others probably didn't understand what was going on. Seeing Feng Wei lose his composure, his expression became more and more confused. Yunyang felt angry and called a student out at random, asking him: "Do you understand? ? "The student Na Na shook his head: "The student doesn't understand. " Yunyang held the chalk and said with anger: "We have already concluded that the vertex angle is 4.5 degrees, right? "The student nodded with a blank look on his face. "Thenits opposite angle must also be 4.5 degrees, right? " "Yes. "The student murmured. "Look at the blackboard! Yunyang yelled, "Since this angle is also 4.5 degrees, and these two lines are parallel lines, then the central angle of the circle is naturally 4.5 degrees!" So the size of the vertex angle of the triangle is the size of the central angle! Don¡¯t you understand yet? "The student trembled all over, and then a burst of ecstasy appeared on his face: "So that's it! I see! Students understand, students understand! " "Elm head. "Yun Yang snorted and waved his hand casually, and the student cheeredWent back happily. At this time, everyone in the audience probably understood what was going on, so the noise broke out. "I have been thinking hard for several days. I have thought of every situation, but I have never thought of this level The top corner is really the central corner of the circle. Alas, I am really old and confused." "Mr. Wu is really a genius I feel so ashamed." "It's so simple! Why didn't I think of it before? Alas, the opportunity to become a disciple of Senior Brother is gone" Some people in the crowd looked sad. , some people were ecstatic and had various expressions. Next to them, Zhao Ke and others looked at each other. Although they did not move, they were obviously much more relaxed. An atmosphere of joy emerged between them, and Shi Fangzhuo even turned up the corners of his mouth with joy. Measuring the size of the ancestral star is certainly a big thing, but there is one thing that is even more important than measuring the size of the ancestral star. That is the person who is given by God. Now, Yunyang has really calculated the size of the ancestral star, and everyone is convinced. This has undoubtedly proved that Yunyang is the legendary person given by heaven. ???????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? person.????? Grandmaster Wu Qingyun is a person given by heaven, he single-handedly founded this Shenghua City, which is aloof and independent from the other eleven main cities. The leader of the Wanhua Divine Sect is a man given by heaven. He single-handedly founded the Wanhua Divine Sect. His cultivation is unfathomable. All the remaining eleven main cities are under his rule. And at this moment Yunyang has also become a person given by heaven? This is great news, but Zhao Ke and others have already agreed to keep it a secret to prevent Yunyang from becoming arrogant and affecting Yunyang's growth. Therefore, a few people remained calm and just watched indifferently. "No!" At this time, someone suddenly shouted, "This method can certainly determine that the vertex angle is the central angle, but how to determine that the circle is the longest circumference of the ancestral star? After all, the ancestral star is a ball , not round!" Yunyang glanced at the student lightly, with a hint of appreciation in his eyes. To be able to think of this problem, compared to the development level of astronomy and mathematics in Shenghua City, it is already very simple. Yunyang smiled and said: "Do you know why I want Dean Feng, General Sun, and Zhao Heilian to all wear high hats?" The man said in a daze: "Why?" "Because I want the three of them to go to the main place. In the south direction, you have to keep walking in a straight line. And why do you have to keep walking in a straight line? "The man was still stunned and said: "Why?" After the student raised this question, many people immediately asked. I was inspired and thought about this problem. So for a moment, all the noise disappeared again, and all eyes focused on Yunyang again. Zhao Ke also frowned slightly, while Shi Fangzhuo showed a little worry on his face. "Because there are South Pole and North Pole on the Ancestral Planet" Yunyang sighed, "As long as you go north, you will definitely reach the North Pole, and as long as you go south, you will definitely reach the South Pole, so keep walking in a straight line south, and then measure The circle must pass through the South Pole and the North Pole at the same time, and the circle that passes through the South Pole and the North Pole at the same time Do you think it is the longest circumference on the ancestral planet?" The student thought for a moment, and suddenly patted his head. : "I see, the students have figured it out." Yunyang nodded, and then asked: "Do you still have any objections?" Everyone was silent, no one spoke. Yunyang spread his hands again: "I said that I will fully use the knowledge I have mentioned and calculate the size of the ancestral star through these public data In the process just now, have I ever used other methods? Knowledge about parallel lines, radian angles, trigonometric functions, etc. Which one have I not mentioned? " "No" There was a sporadic response from the audience, looking a little frustrated. "That's good." Yunyang said with a smile: "No one has found the final answer before me So this time, it seems that the senior brother will not be able to accept a disciple. But it doesn't matter, everyone still has a chance again After a while, I will start to measure the distance between the moon and the sun, as well as Chenxing, Changgeng, Yinghuo, Zhenxing, Suixing and us If you perform well, you will still have the opportunity to become senior brother's disciples." Zhao Ke. At this time, he stood up at the right time and said expressionlessly: "What Xiaoyun said is correct." "Really?" Many people immediately became excited. At this moment, I don't know how many people secretly made up their minds. determined. "Once againI announce something to everyone." Yunyang said, "Because of my limited energyI will hold an exam. From now on, only those who pass the exam can come to my class."Only those who attend the lectures in the middle school are qualified to ask me questions and get my answers. Thirty people are initially scheduled to be recruited, and the remaining students will wait until these thirty people graduate to ask them for advice. " "What? ! "As soon as Yunyang's words came out, it immediately caused an uproar. ¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª¡ª A six-thousand-word chapter! Today's two updates are all here. Tomorrow's update will probably be a little later, and 80% of it will be There is only one update There are too many things to do during the Chinese New Year. Caihong has been staying in Hainan for two months, and things have piled up until now I beg everyone for your understanding.
