"Um, Chou Niu and Huai Yu are you two here?"
When he arrived at the teaching building, he saw the tall and handsome Cheng Chumo and the elegant Qin Huaiyu sitting behind him. Li Zexuan remembered the day when Cheng Yaojin and other senior generals entrusted their sons to the arithmetic school. However, he did not expect these generals. The second generation came here today.
Cheng Chumo lowered his head and said feebly:
"Brother, I don't want to come either, but my dad said he would break my legs if I didn't come. I thought he was trying to scare me, but who knew he actually came this morning? My mother couldn't hold her back. , Fortunately, brother, I ran fast, otherwise I would be lying in the Imperial Medical Office now. Oh, Xiaoxuan, we were brothers, and now you suddenly became my teacher for no reason, this is really fucking annoying Yes!"
Li Zexuan almost laughed out loud when he heard Cheng Chumo's complaint. He really didn't expect Cheng Yaojin to be so cruel to his son.
He was about to say something to comfort him, when Qin Huaiyu on the side smiled and said: "Chou Niu, Uncle Cheng is doing this for your own good. Since you are here, you should study hard. Besides, I just borrowed the notes of other classmates. , I found that Xiaoxuan’s new arithmetic does have many merits..."
"Stop, stop, stop, Huaiyu, stop talking. Of course you don't care if you have good grades, but look at me, Old Cheng, how do I look like a scholar? I just heard that the last five in the monthly exam of the school have to be cleaned up. Why should I be put on the list of shame in the teaching building? I really don’t know who had this bad idea, but it killed me, Old Cheng!"
Cheng Chu didn't wait for Qin Huaiyu to finish and interrupted directly. He spoke so loudly that eight CDs of people in the classroom heard it. The noisy classroom instantly fell silent. Except for the three newcomers Cheng Chumo, all the other students looked at this man who dared to say such arrogant words in shock. God man.
Li Zexuan's old face darkened, and he kicked Cheng Chumo's thigh, "Damn, I came up with this idea. If you get into the bottom five in the exam this month, you will clean the classroom for me for two months!"
Cheng Chumo was kicked and staggered. After listening to Li Zexuan's words, his eyes widened and he looked confused. He stretched out his hand and said, "Hey, hey, Xiaoxuan, stop! What's the relationship between us two brothers? It's useful." Is this the case? Just treat me like a fart!"
"Hahaha!"
When the students saw Cheng Chumo playing tricks, they couldn't help laughing. Many of them knew the identities of Cheng Chumo and others. Those who didn't know knew it after private inquiries. They thought that these second-generation generals were quite arrogant, but they didn't expect that Cheng Chumo would be so funny. Hey, he's no different from ordinary people like them.
Li Zexuan ignored Cheng Chumo, looked at the dark and fat young man next to Qin Huaiyu, and asked, "Are you Yuchi Baolin?"
The chubby guy scratched his head and said with a smile: "Yeah, I am Yuchi Baolin, sir, just call me Baolin!"
Li Zexuan nodded and encouraged: "Okay, Paulin, study hard. If you don't understand anything, you can ask Tiedan, or you can ask me directly."
Cheng Chumo murmured to the side: "Tsk, what's there to learn from him? In the end, he's not going to compete with me for last place!"
Li Zexuan was so angry that he gave him a slap on the head. "If you really come last in the exam, I will see how Uncle Cheng deals with you. I won't recognize you, this embarrassing brother!"
Cheng Chumo rubbed his head and looked at him with an aggrieved look like an angry little wife, muttering: "Xiaoxuan, you are not kind! Brother, I am usually so nice to you, how can you do this?"
"What's going on? Even I, the king, have to do what my husband wants here. What else do you want, Chou Niu?"
Li Tai happened to be visiting the academy today. As soon as he came in, he heard Cheng Chumo's aggrieved complaint and couldn't help but interject.
Cheng Chumo looked at Li Tai in surprise, opened his mouth, and wanted to say something, but in the end he said nothing. He put his hand on his forehead and sighed, seemingly completely resigned to his fate.
... ... ... ... ... ..
"Okay, let's start class! Students, take out your homework. Tiedan, go collect your homework and give it to me!"
Several bells and drums could be heard outside. This was a watchman hired by Li Zexuan to ring the bell for the arithmetic school. When the bell rang, Li Zexuan started a new day of classes.
"Yes, Master!"
Tiedan stood up and collected his homework one by one. When he came in the morning, he had just distributed new books to all the students one by one. In addition, he was Li Zexuan's direct disciple, so the students all treated him very well.
After a while, Li Zexuan took everyone's homework and started reading it in detail. After a while, he frowned and shouted: "Wang Meng, get up!"
Wang Meng was sitting below, waiting for Li Zexuan to praise him. He thought about his homework for a long time before he came up with it, but judging from Li Zexuan's current tone, it was obvious that he was not praising him.
Wang Meng stood up with a look of astonishment on his face and stammered: "First... sir!"
"Tell everyone, what method is written in your homework?"
Wang Mengnahan said: "Well, I... What I wrote was, cut down the ginkgo tree, and then connect several rulers together on the ground to measure!"
"Hahaha"
The students burst into laughter after hearing this.
Cheng Chumo was also happy. He laughed and shouted: "Haha, brother Wang Meng, with you here, it seems that I, old Cheng, don't have to be in the last place in the exam, haha!"
Li Zexuan asked everyone to be quiet, looked at Wang Meng and said: "Now do you know that you are wrong? I teach you arithmetic so that you can use what you have learned in your life, not to let you continue to be like before. That way, everything depends on brute force!”
Wang Meng hesitated for a while and said unconvinced: "But my father said that when he was doing carpentry work, he used this method to measure the length of tree trunks!"
Li Zexuan: ... ... ... ... ... ...
... ... ... ... ... ...
After talking to Wang Meng for a long time, he finally convinced this stubborn guy. Li Zexuan began to select the winners of this assignment. All the students were shocked and listened carefully.
"After repeated consideration, I found that Meng Wenhao did the best job in this assignment. His method was to measure the length of the shadow of a person and a tree at the same time, and multiply the length of the tree shadow by the actual height of the person and the human body. proportion, you can get the true length of the ginkgo tree.
In addition to Meng Wenhao, Li Tai's method is also very brilliant. He puts the human eye close to the ground, and then moves a ruler until the top of the ruler is in the same straight line with the human eye and the top of the tree. The ratio of the distance to the human eye and the distance from the city ruler to the human eye, multiplied by the length of the city ruler, gives the true height of the ginkgo tree.
The methods of the two of them are the smartest and the best, but in comparison, I think Meng Wenhao's method is simpler and more accurate. He deserves the first place. Let us give applause to these two students! "
