"Uh, Chou Niu, Huaiyu, you two are here?"
When he arrived at the classroom, he saw the tall and burly Cheng Chumo and the refined Qin Huaiyu sitting at the back. Li Zexuan recalled that day when Cheng Chumo and the other old generals had entrusted their sons to the school of mathematics. However, he didn't expect that these second generation generals would come today.
Cheng Chumo hung his head and said weakly, "Brother, I didn't want to come.
"Brother, I didn't want to come either, but my father said that if I didn't come, he would break my legs. I thought he was just scaring me, but who knew that he was serious this morning. Even my mother couldn't hold him back. Fortunately, I ran fast, or else I would be lying in the Imperial Medical Department now. Sigh, Xiao Xuan, we used to be brothers. Now you suddenly became my teacher for no reason. This is so f * cking disgusting! "
When Li Zexuan heard Cheng Chumo's complaints, he almost laughed out loud. He didn't expect Cheng Chumo to be so cruel to his own son.
He was about to comfort him when Qin Huaiyu said with a smile, "Chou Niu, Uncle Cheng is doing this for your own good. Since you're here, you should learn well. Moreover, I just borrowed the notes of other classmates and found that Xiao Xuan's new mathematics has many merits … "
"Stop, stop, stop. Huaiyu, don't say anymore. Your grades are good, so of course you don't care. But look at me, Old Cheng, how do I look like a scholar? I just heard that the last five in the monthly exam will have to clean the classroom and enter the Roll of Shame. I really don't know which son of a bitch came up with this rotten idea. It's going to kill me! "
Cheng Chumo didn't wait for Qin Huaiyu to finish and interrupted him. His voice was very loud. Eighty percent of the people in the classroom heard him. The noisy classroom instantly quieted down. Other than Cheng Chumo and the other two newcomers, all the other students looked at this man who dared to speak so arrogantly.
Li Zexuan's face darkened. He kicked Cheng Chumo's thigh and said, "F * ck, I was the one who came up with this idea. If you're in the last five this month, you'll have to clean my dorm for two months!"
Cheng Chumo staggered from the kick. When he heard Li Zexuan's words, his eyes widened in shock. He stretched out his hand and stammered, "Hey, hey, hey, Xiaoxuan, don't! What kind of relationship do we have? Is there a need to be like this? Just treat me as a fart and let me go! "
"Hahaha!"
When the students saw Cheng Chumo's antics, they couldn't help but burst into laughter. Many of them knew the identities of Cheng Chumo and the others. Those who didn't know found out after asking them in private. They thought that these second-generation generals were all arrogant, but they didn't expect Cheng Chumo to be so funny. He was no different from ordinary people like them.
Li Zexuan ignored Cheng Chumo. He looked at the tanned and fat youth beside Qin Huaiyu and asked, "You're Yuchi Baolin, right?"
The little fatty scratched his head and laughed, "Yes, yes, I'm Yuchi Baolin. You can call me Bao Lin, sir!"
Li Zexuan nodded and encouraged him, "Okay, Bao Lin, study hard. If there's anything you don't understand, you can ask Iron Egg or me directly."
Cheng Chumo muttered at the side, "Tsk, what's there to learn from him? In the end, he still has to fight with me for the last place!"
Li Zexuan was so angry that he turned around and slapped him on the head. "If you really get last place in the exam, we'll see how Uncle Cheng will deal with you. I won't recognize you as a disgraceful brother!"
Cheng Chumo rubbed his head like a wronged wife. He looked at him with an aggrieved expression and muttered, "Little Xuan, you're not kind! I've always been so good to you. How can you be like this? "
"Like what? Even I have to do as Sir says. What else do you want, Ugly Ox? "
Li Tai had just arrived at the academy on time. He heard Cheng Chumo's aggrieved complaints and couldn't help but interrupt.
Cheng Chumo looked at Li Tai in surprise. He opened his mouth and wanted to say something, but in the end, he didn't say anything. He held his forehead with his hand and sighed. It seemed like he had completely accepted his fate.
.....
"Alright, let's start class! Students, take out your homework. Iron Egg, go collect your homework and pass it to me! "
The sound of a bell and drum came from outside. Li Zexuan had hired a night watchman to ring the "bell" for the academy. When the bell rang, Li Zexuan started a new day of classes.
"Yes, Master!"
Iron Egg stood up and collected the homework one by one. He had just handed out new books to all the students when he arrived in the morning. In addition, he was Li Zexuan's eldest disciple, so the students treated him very well.
After a while, Li Zexuan took everyone's homework and skimmed through it. After a while, he frowned and shouted, "Wang Meng, get up!"
Wang Meng sat down and waited for Li Zexuan to praise him. He had thought for a long time before coming up with the homework. However, judging from Li Zexuan's tone, it was obvious that he wasn't going to praise him.
Wang Meng stood up in shock and stuttered, "S-Sir!"
"Tell us, what method did you write in your homework?"
Wang Meng sweated and said, "Erm, I … I wrote that if you saw the ginkgo tree down, then connect a few rulers on the ground to measure the height of the tree, you would be able to get the height of the tree!"
"Hahaha!"
The students burst into laughter after hearing this.
Cheng Chumo was also amused. He laughed and shouted, "Haha, Brother Wang Meng, with you here, it seems like I don't have to be the last in the exam. Haha!"
Li Zexuan asked everyone to be quiet. He looked at Wang Meng and said, "Now do you know that you were wrong? The reason why I'm teaching you mathematics is so that you can apply what you've learned in your daily life. I don't want you to be like before, relying on brute force for everything! "
Wang Meng hesitated for a while and said, "But my dad said that when he was doing carpentry, he used this method to measure the length of the tree trunk!"
Li Zexuan was speechless.
.....
After wasting a lot of time with Wang Meng, Li Zexuan finally convinced this one-track minded guy. Then, he began to evaluate the winners of the homework. All the students perked up and listened attentively.
"After much deliberation, I think that Meng Wenhao did the best homework. His method was to measure the length of the shadow of the person and the tree at the same time. Then, he multiplied the length of the shadow of the person and the actual height of the person to get the true length of the ginkgo tree.
"Other than Meng Wenhao, Li Tai's method was also outstanding. He made the person's eyes stick close to the ground and then moved a ruler until the top of the ruler was in a straight line with the person's eyes and the tip of the tree. Then, according to the ratio of the distance between the person's eyes and the ruler's distance, he multiplied the length of the ruler to get the true height of the ginkgo tree.
Both of their methods were the smartest and the best. However, I think that Meng Wenhao's method is simpler and more accurate. He deserves to be first. Let us give a round of applause to these two students! "
