Training the Heavens

Chapter 149: There is a Ning Bi in our school?
This question is not difficult. It is a basic question about trigonometric function equations in high school. Anyone who has learned the basics can solve it. But Zhuang Tunan is only eleven years old. It is surprising that he wrote out the answer so neatly.

Yao Xiuhua wanted to try a few more complicated questions, but considering that it was still class time, she suppressed her excitement, asked Zhuang Tunan to go back, and continued teaching the students herself.

Zhuang Tunan picked up the "High School Mathematics" textbook again and started flipping through it. This time, Yao Xiuhua didn't stop him. "He even understands trigonometric equations, so how much more so elementary geometry?" she asked. "Let him read it."

After finally waiting for the get out of class to end, Yao Xiuhua pulled Zhuang Tunan out and said, "Come with me to the office."

With a clatter, several students who were usually good at studying immediately ran to Zhuang Tunan's desk and picked up "High School Mathematics" to read it. They were even trying to compete with Zhuang Tunan. My grades are usually about the same as his. It doesn't make sense that if he can understand the book, I can't, right?

However, they were just children after all, and there was no genius like Terence Tao in the class. They put the book down dejectedly after flipping through a few pages. This thing was like a heavenly book to them, and their minds were filled with confusion after reading it.

Yao Xiuhua pulled Zhuang Tunan into the office, asked him to sit down at her desk, and began to think about what kind of questions to give him. After thinking about it for a long time, she couldn't find a suitable one. She had taught elementary school mathematics for so many years, and her impression of high school knowledge was already very vague.

Ah, I got it. She quickly opened the drawer, took out the math problems she had copied from the college entrance examination a few days ago and placed them in front of Zhuang Tunan. She then found a pen and paper and handed them to him. "See if there are any questions you know how to do? If so, do them. If not, forget it. I'll find another way."

"Okay." Zhuang Tunan took the test paper and started reading it.

For a PhD student from a top university, these questions weren't difficult. Zhuang Tunan picked up a pen and began calculating on a piece of scratch paper, writing down the answers one by one:
1. Original formula=99.
2、函数的定义域为2≤x<3和3<x<5.
3. x=1 and x=-3 are both solutions to the original equation.

4.
This was the first test paper after the resumption of the college entrance examination. Due to the hasty preparation, the relevant departments did not immediately announce the standard answers. Yao Xiuhua could only watch Zhuang Tuanan write one question and then take out the answers to her previous questions for comparison.

The answers she was sure of were basically the same as Zhuang Tunan's, and for those she was not sure of, Zhuang Tunan's problem-solving process seemed more credible than her own.

Unconsciously, the ten minutes between classes passed quickly, and the teacher in the same office couldn't help but remind him, "Teacher Yao, it's time to start class."

Yao Xiuhua finally woke up. She had no intention of attending class. She took a look at the schedule and asked another teacher for help. "Teacher Zhang, can you do me a favor? Next period, you can go to Class 2's math class. I'll go to their math class tomorrow."

"Okay, but what's going on with you now?" Teacher Zhang asked curiously.

"I have to supervise Zhuang Tuanan while he takes the test. Maybe our school will also produce a Ning Bi!" Yao Xiuhua watched Zhuang Tuanan answering the questions, her eyes full of excitement.

"Ning Bi? Oh, is that the child prodigy mentioned in the newspaper a while ago?" Upon hearing this, the whole office was shocked, and all the teachers came over to watch, because Ning Bi was so popular this year.

Ning Bi was born in Ganzhou, Jiangxi Province in 1965. When he was 2 and a half years old, he could recite more than 30 poems written by teachers. When he was 3 years old, he could count to 100. When he was 4 years old, he learned more than 400 Chinese characters. When he was 5 years old, he entered the primary school for children of the power supply bureau ahead of schedule.

Later, he was sent down to the countryside with his parents. Although he had no schooling, he did not run around everywhere. Instead, he stayed at home patiently and read books. He read Tang poetry, Song lyrics, medical books, chess manuals, whatever he could find, and he was so absorbed in them that ordinary people were no match for him in chess.

Many people think that Ning Bi is a genius. Ning Bi's father had a friend who was a university teacher. He believed that if such a genius was well cultivated, he would definitely become a great scientist. So he wrote a letter to Fang Zong, who was then the Vice Premier of the State Council and President of the Chinese Academy of Sciences, recommending this genius boy who was only 11 years old.

Mr. Fang forwarded this letter to the University of Science and Technology of China, which was a subordinate unit of the Chinese Academy of Sciences at the time. There was a note on it, "If it is true, he should be admitted to the university as an exception." USTC did not dare to neglect it and immediately sent people to the local area to investigate Ning Bi's level. The test was in mathematics, and there were two precocious teenagers participating at the same time. Ning Bi scored 67 points, ranking second, the first place scored more than 80 points, and the third place scored 64 points.

Ning Bi's talent was confirmed, and USTC admitted him as an exception. However, it is unknown why the other two teenagers were not selected.

This incident was reported in many newspapers, and people all over the country knew about this talented young man overnight. The teachers of the primary school attached to the cotton mill had also heard of their names. Some people even joked, saying why our school had not produced a Ning Bi. Unexpectedly, Zhuang Tunan gave them a big surprise today.

It was when Zhuang Tunan saw the name Ning Bi in the newspaper that he came up with the idea of ​​playing the role of a genius boy. Firstly, if he grew up earlier, he could help Huang Ling and Zhuang Xiaoting get rid of Zhuang Chaoying sooner. Secondly, he has an adult soul in his body, and it would be too difficult for him to go through elementary school, junior high school, and high school step by step.

It would be better to seize this opportunity of Ning Bi and see if there are any universities that would also recruit me, so that I can kill two birds with one stone.

The bell rang, and the teachers who had classes left without turning back. Yao Xiuhua didn't let Zhuang Tunan go back to the classroom, "Tunan, continue working on your homework."

"Oh." Zhuang Tunan ignored the onlookers of other teachers and continued to work on the questions.

Yao Xiuhua pulled another math teacher, Zhao Liwei, aside and whispered, "Can you tell what he did right? I can only understand three questions."

"I only know four of them. I don't quite understand the others." Zhao Liwei blushed. He was already in his thirties and had taught math for more than ten years, but he didn't expect that he was not even as good as a primary school student.

"Why don't you ask Mr. He Chengxuan to come over and help take a look? He used to be a university math teacher, so he's sure he can understand it."

"Okay, I'll go." Zhao Liwei ran out quickly. He Chengxuan used to be a teacher at Jiangsu Normal University. He was demoted to the affiliated primary school as a teacher a few years ago.

Soon, He Chengxuan, a man in his fifties wearing glasses, came over. He watched Zhuang Tunan do the questions silently without saying a word. He ignored Yao Xiuhua's questions, and the other teachers could only watch out of curiosity.

After another twenty minutes, Zhuang Tunan put down his pen and said, "I have done everything I know how to do. I haven't learned the rest yet."

"Teacher He, how much did he get right?" Yao Xiuhua and Zhao Liwei asked in unison. They were already very anxious.

"All correct. He got all the questions right, not a single one wrong." He Chengxuan said in surprise. He had done the college entrance examination questions himself since they were announced, and Zhuang Tunan's answers were exactly the same as his.

Huh? Our school really has a Ning Bo!

　Damn, typing math formulas by hand is too tiring, so I'll just take a screenshot
