Chapter Twenty-Eight: Who Is More Precise

Xu Yun had no choice but to speak: "Okay, okay, let's discuss it here, tell me what you think?" ”

The scene, which was still very enthusiastic just now, immediately stopped, and the class representatives repeatedly glanced at the school bully Zhao Zhiyi and the prodigy Wang Qian, and the poor little chubby's small eyes were about to cramp, so Zhao Zhiyi slowly stood up.

He asked Xu Yun, "Master, I'm not quite sure who is right. At the beginning, I also planned to use the snow melting speed to calculate the height of Luofu Mountain, but I thought that there were many factors that affect the snow melting speed, such as light, height, and wind speed. That's why I'll find another way later, using the shadow length to calculate the height of the mountain, and the shadow is only affected by the sun and Luofu Mountain. Therefore, we believe that the method of calculating by the shadow length is more accurate, and the height of Luofu Mountain should be closer to 447 zhang. ”

Xu Yun didn't answer immediately, he nodded and motioned for Zhao Zhiyi to sit down, "Is there anything else you want to say?" ”

Qin Yuanfan muttered, his voice was not loud, but he was still heard by Wan Jinyan who was on the tip of his ear, Wan Jinyan stood up and said with an exaggerated expression: "Yuanfan said that he supports Ah Qian, and in his heart, Ah Qian will always be right!" ”

"Hahahaha......" Zhao Zhiyi gave Qin Yuanfan a fluttering look amid laughter.

Qin Yuanfan: "Zhiyi, don't listen to nonsense, you are the same as Ah Qian in my heart!" "Hurriedly make amends.

Zhao Zhiyi snorted lightly, "Pull it down, I don't know you yet, Ya's heart is all used to pretend to be shallow, where is there still an inch of empty space left for me." ”

Qin Yuanfan: "Zhiyi, you!" The blush was not like words, it was hot, and it quickly spread to the base of the neck.

"Yo yo...... Hahahaha...... "For a while, I squeezed my eyebrows and made my eyes and had bad intentions."

Wang Qian subconsciously wanted to wave the nine-section whip to cure them, and when his hand touched his waist, he found that he didn't have it today, so he had to withdraw his hand, palm strength, and shoot the case, "What are you laughing at!" ”

It's a pity that Xu Yun was there, everyone knew that they had a backer, and the laughter was not as if it was immediately silent on weekdays, but only a little weaker.

Wang Qian saw that he didn't bluff people this time, so he was so angry that he immediately stood up, "Don't think that if the master is here, I won't be able to rule you, don't even think about leaving after school!" ”

Everyone was afraid that they would remember the tragic situation of being suppressed by force countless times before, and they all closed their mouths. Wang Qian sat down satisfied, and she said to Xu Yun: "Master, you can directly say the result, what can these fools think?" ”

Even if the fools were so angry, they didn't dare to speak anymore, so they had to secretly raise their middle fingers in their hearts and despise Wang Qian ten thousand times, the prodigy is amazing? Hum!

Xu Yun let them make trouble, he thought, there are not many years in life to be wanton, and he doesn't want to deprive them of their young time.

Xu Yun: "Okay, if you delay any longer, you don't plan to have lunch today?" ”

Zhu Zhen: "Master, you can say it, we will all wait to hear it." ”

Xu Yun glanced around, his shining eyes were indeed like nesting birds waiting to be fed, and he smiled and said, "Before announcing the results, I want to ask you one more question." ”

"Do you know that when the spring of Bianliang comes, does the spring of the entire Great Song Dynasty start at the same time?"

Qin Yuanfan: "No, when I followed the caravan to the Hopeless Sea before, although I didn't go to the beach that time, I ended up staying in Fujian for five days. I remember very clearly that it was the golden autumn and October when I set off from Bianliang, and it took a whole month on the way, so it stands to reason that it should be just in time for the cold winter, but Fujian is still warm and beautiful, and the people of Fujian are still wearing single clothes. ”

Xu Yun nodded: "What Yuan Fan said is right, at the same time, the different regions of the Great Song Dynasty are very different. In some places, it is snowing heavily, and in others it is still summer. This is the first point I want to teach you today, geographical knowledge is not only reflected in the mountains, rivers and currents, it is also closely related to our lives, maybe we can feel only in the clothes, but for the sunrise and sunset of the farmers, it is a major matter for the whole family, when to sow seeds, how many seasons a year, whether the rain is enough, etc., will affect their harvest throughout the year, and this harvest determines whether their family eats white flour steamed buns or gnaws old bark. When he said the word bark, Xu Yun was extremely embarrassed, and he unconsciously looked at the initiator - with a blank expression, it seemed that she had no impression of being drunk at all.

Xu Yun: "The first point I just said, do you understand? ”

He began to pound the garlic again, "We see, Master. ”

Xu Yun: "Okay, then I'll continue." The temperature difference between the foot of the mountain and the summit is due to the difference in height, which we have already discussed, and there is no problem. Then I want to ask you now, what is the reason for the temperature difference between the different state capitals of the Great Song Dynasty? ”

"Is it because the state capitals are too far apart?" Wan Jinyan scratched his head and asked puzzled.

"Could it be because of the height?" Li Shui slapped his head.

Xu Yun: "Well, you two are right. ”

"Huh? All right? The crowd was puzzled.

Xu Yun nodded: "Yes, it's just that not any distance will bring a temperature difference, for example, I once followed the source of the Bianhe River all the way to the east, except for Tanggula Mountain, the rest of the state capitals are the same; But when I went south from Mongolia to the Hopeless Sea, I could clearly feel the difference, and the winter in Mongolia is particularly long, while the summer in Fujian is particularly long. As I walked a little further, I came to the conclusion that the distance between north and south causes the temperature difference, but not in the east-west direction. ”

"Wow! It's amazing! "The students were amazed at something they had never written about in books and in a field they had never set foot in.

Xu Yun pulled the corners of his mouth slightly: "At the same time, height will also lead to temperature differences." Now considering this factor, you can think about it again, which is more accurate, Zhiyi or Wang Qian's method? ”

Zhao Zhiyi condensed his eyebrows and said in a deep voice: "It's Ah Qian, and the speed of snow melting will not be limited by geography, that is to say, the six hundred zhang calculated by Ah Qian can be compared with the mountains in all places in the Great Song Dynasty." The shadow length is based on the height of Bianliang itself, and the height of 447 zhang plus Bianliang City should be equivalent to 600 zhang of A Qian, indicating that Bianliang is higher than the general height of the entire Great Song Dynasty! ”

As soon as Zhao Zhiyi's voice fell, the audience was silent, and Xu Yun couldn't help laughing as he looked at the stupid students one by one. He was the first to applaud, and there were three crisp applause, which woke up the students who were not possessed, and then the applause continued.

"Zhiyi is so powerful, although I didn't understand a word, but I just feel amazing!"

"Yes, yes, I almost thought Zhiyi was speaking Mongolian hahahaha......"

"Huh? So you didn't understand it either, did you? So why do we applaud for? ”

"Stupid, say you're stupid, you're still screaming, right, it's the master who applauded, which means that we Zhiyi must be right."

"Oh oh yes, I can't see it, you're not too stupid."

"You're stupid, you're stupid and stupid hahahaha......"

Xu Yun didn't hear what the voice mixed with applause was saying, he supported the chair, his left leg strained, and stood up, hey, still clapping, doesn't his hand hurt??

I don't know who suddenly howled: "What about the master? ”
