Otaku Engineer in Great Tang Dynasty Chapter 174: New students come to report

"Uh, Ugly Cow and Huaiyu are you two here?"

　　When I came to the teaching house, I saw the man Gaoma Dacheng Chumo and the gentle Qin Huaiyu sitting behind. Li Zexuan remembered the day that Cheng Yaojin and other veterans entrusted his son to the school, but he did not expect this. Several second generation generals came here today.

　　 Cheng Chu silently pulled his head, and said weakly:

　　" Brother, I don’t want to come, but my father said, I would break my leg if I didn’t come. I thought he was frightening me. Who knew he actually came this morning this morning, my mother Ladu I can’t hold it. Fortunately, my brother, I’m running fast, or I should be lying in the Imperial Medical Office now. Alas, Xiaoxuan, we were brothers, and now you suddenly became my teacher for no reason. This is really him. Mother's diaphragm!"

　　 Li Zexuan almost didn't laugh when he heard Cheng Chumo's complaint. He didn't expect Cheng Yaojin to be so cruel to his son.

　　 He was about to say a few words to comfort him, at this moment Qin Huaiyu smiled and said: "Ugly cow, Uncle Cheng is also for your good. Now that you are here, you should study hard. Besides, I just borrowed others. Classmates’ notes, Xian Xiaoxuan’s new mathematics does have many merits..."

　　"Stop, stop, Huaiyu, don't talk about it, you have good grades, of course you don’t care, but look at my old Cheng, where does it look like a scholar! I just heard that this is the last five of the monthly exams I want to clean up the teaching house and enter the stigma list. I really don’t know which tortoise son thought of the bad idea, but it killed my old Cheng!"

　　 Cheng Chu did not wait for Qin Huaiyu to finish, so he interrupted. He spoke very loudly. Eight cds of everyone in the teaching house heard it. The noisy teaching house fell silent in an instant. Except for the three new arrivals from Cheng Chumo, all the other students looked at this man who dared to speak wildly in shock. God man.

　　 Li Zexuan’s old face turned black, and he hit Cheng Chumo’s thigh with a kick, "Slot, this idea came from Lao Tzu. If you get the last five in this month, you will give me two months of teaching. Give up!"

　　 Cheng Chumo was kicked for a while, and after listening to Li Zexuan's words, his eyes widened, his face was dumbfounded, and he stretched out his hand and said: "Ah, oh, Xiaoxuan, don’t! What is the relationship between our brothers? , Do you need this? You just let it out as if I was a fart!"

　　 "Hahaha!"

　　 When the students saw Cheng Chumo playing with treasures, they couldn't help laughing. As for the identities of Cheng Chumo, many of them were aware of them. After inquiring privately for those who didn’t know, they all knew. They thought that the second generation of these generals were quite arrogant, but they didn’t expect Cheng Chumo to be so funny. Compared to ordinary people like them, it's no different.

　　 Li Zexuan ignored Cheng Chushi, looked at the dark and fat boy next to Qin Huaiyu, and asked, "You are Yuchi Baolin, right?"

　　 The chubby scratched his head, hehe smiled and said, "Yeah, I am Yuchi Baolin, and my husband can call me Baolin!"

　　Li Zexuan nodded and encouraged: "Okay, Pauline, you study hard. If you don't understand, you can ask the iron egg or just ask me."

　　 Cheng Chu silently muttered to the side: "Cut, what he has to learn, in the end he won't be the last one with me!"

　　 Li Zexuan was very angry, and slapped him on the head reflexively, "You are going to be the last one in the test, and I will not recognize you as a shameful brother when I see how Uncle Cheng cleans up you!"

　　 Cheng Chu silently rubbed his head, looked at him aggrievedly like an angry little daughter-in-law, and mumbled: "Xiaoxuan, you are not kind! Brother, I usually treat you so well, why can you do this?" /

　　 "Which is it? Even this king has to do what his husband wants here, what do you want to do with Ugly Bull?"

　　 Li Tai just stepped on to the academy today. As soon as he came in, he heard Cheng Chumo's grievances and couldn't help but interject.

　　 Cheng Chumo looked at Li Tai in surprise, opened his mouth, trying to say something, but in the end he said nothing. He held his forehead with his hand and sighed, which seemed to be a complete confession.

　　..............

　　 "Okay, let's start the class! Students, take out your homework, Tiedan, you go and collect the homework for me!"

　　 There were a few bells and drums outside. Li Zexuan hired a watchman to ring the bell for the school. Hearing the class bell ringing, Li Zexuan started another day of classes.

　　 "Yes, Master!"

　　 Tiedan stood up and collected work one by one. When he came in the morning, he had just given all the students new books one by one, and he was also Li Zexuan's major disciple, so the students had a very good attitude towards him.

　　 After a while, Li Zexuan took everyone's homework and looked at it in a row. After a while, he frowned and shouted: "Wang Meng, you get me up!"

　　 Wang Meng sat down and waited for Li Zexuan to praise him. His homework was thought of for a long time before he came up with it, but listening to Li Zexuan's current tone, it was obviously not to praise him.

　　 Wang Meng stood up with a look of error, and stuttered: "First... Sir!"

　　" Tell everyone, what method did you write on your homework?"

　　 Wang Meng Nahan said: "Uh, I...I wrote that I saw the ginkgo tree down, and then measured it with several rulers on the ground!"

　　"hahaha"

　　The students burst into laughter after hearing it.

　　 Cheng Chu was also happy. He laughed and yelled: "Haha, brother Wang Meng, with you, it seems that I don’t need to take the test to be the last one, 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 and use it in your lives, not for you As before, everything depends on brute force!"

　　 Wang Meng hesitated for a while, and said unconvinced: "But my father said~IndoMTL.com~When he was doing woodwork, he used this method to measure the length of the trunk!"

　　Li Zexuan:...............

　　...............

　　 spent a long time inking with Wang Meng, and finally persuaded this stubborn product. Li Zexuan began to compare the winners of this assignment. All the students were shocked and listened carefully.

　　"After careful consideration, Meng Wenhao did the best job for this homework. His method is to measure the length of the shadows of people and trees at the same time, and multiply the length of the shadows by the shadows The actual height ratio of the human body gives the true length of the ginkgo tree.

　　 In addition to Meng Wenhao, Li Tai's method is also very brilliant. He makes people's eyes close to the ground, and then moves a market ruler until the top of the market ruler is in a straight line with the eyes and the tree tip. , According to the ratio of the distance from the tree to the human eye and the distance from the market ruler to the human eye, multiply the length of the market ruler to get the true height of the ginkgo tree.

　　The method of the two of them is the smartest and the best, but in comparison, I think it is Meng Wenhao's method which is simpler and more accurate, and he deserves the first. Let us give the applause to these two students! "
