Chapter 25: Admiration
Ring, ring, ring...
The bell for the end of the night self-study class rang, and the training class had no special arrangement and was based on the time of the night self-study class. From 6:30 to 9:00, it was exactly two and a half hours.
Duan Hong was patrolling the room, and when he walked to Wu Tong's desk, he took a look. Wu Tong had already turned a page and was working on question number seven. The draft paper with densely written deduction formulas and processes was piled up on the corner of the desk, almost a finger joint thick.
In other words, from the time he gave Wu Tong these papers to now, about an hour and a half had passed. While other people in the class were still struggling with the provincial competition questions, she had already finished six more difficult national competition questions. This speed and gap shocked him once again!
He didn't know what the geniuses in other provinces and cities were like, but this student named Wu Tong gave him the ambition to hope for national competitions or even the national team.
When the bell rang, Duan Hong announced that the time was up. When collecting the papers, only a few students in the class had finished the four questions. In the past, he might have been disappointed and angry, but today, because of Wu Tong, Duan Hong rarely said anything. He collected the papers and let them go home.
Today, this group of useless people have been affected enough by Wu Tong's attack.
Sun Chao finished his tangle of thinking. Although he had done the last question, he felt that he might have gone in the wrong direction. He turned back to Wu Tong and asked, "Boss, how did you do the last question?"
Wu Tong paused to clean up. The title of "big brother" made her feel a little weird! However, Wu Tong was not a person who cared about things. She took out the draft paper she had just picked up and said, "This is my idea. Take a look!"
"Define a set A=···, where N is a set of positive integers. ···Since a is an infinite set, now arrange the elements in A in ascending order into an infinite sequence. ···Determine the relationship between n and m, k. ···Therefore, the condition is satisfied!"
"Thank you!" The boss's guidance and the deduction process on the draft paper were very clear. If he still didn't understand, Sun Chao felt that he could withdraw from the competition directly.
Waving her hand, signaling Sun Chao that he was welcome, Wu Tong packed up her bag and left the teaching and research room. She was not very good at proactive communication, and the first thing she did after class was to pack up her schoolbag and go home. With the questions given by Teacher Duan today, she could even skip the step of going back to the classroom!
The others were a little slower and missed the chance to make friends with Wu Tong. The few who were closer couldn't help but angrily pat Sun Chao, who had the advantage.
"Old Sun, you are not kind enough to enjoy the master's advice for yourself!" It was this bastard who misled them, they also wanted to be guided by the master! If they didn't think there would be another chance in the future, they really wanted to drag this bastard who took the lead and beat him up!
Little did she know that Wu Tong had already received special permission from Duan Hong, allowing her to study the national competition questions slowly and at her own pace without having to follow the large class.
The next few classes were mainly used to talk about the test papers that Wu Tong had done today. Wu Tong had already passed with full marks, so why waste Wu Tong's time? This student is very good at learning and self-discipline. Let her arrange it herself and she will get more!
In other words, Wu Tong does not need to attend the next 246 Olympiad training courses. Wu Tong has officially witnessed that the Olympiad questions are just more difficult. The training in the Olympiad class does not involve specific thinking. In the final analysis, it is still just about doing questions!
It was not until the exam that this group of people had the opportunity to meet Wu Tong, which almost made them regret it. After they found out on Thursday that Wu Tong did not have to come to class, they were so angry that they settled the score with Sun Chao. Wu Tong is not aware of the follow-up now!

"Tongtong, here!" Wu Jingzhong was standing in front of the school gate. When he saw his daughter coming out, he immediately greeted her with a smile, took the school bag from Wu Tong's hand, and stuffed a hot pancake into her hand: "Are you hungry? Eat it quickly. It's freshly made. I asked for more crisps!"
Since Wu Tong started to study at night in junior high school, Wu Jingzhong would come to pick Wu Tong up in person at night whenever he was at home, rain or shine. The road to their home was a main road and not too dark, but Wu Jingzhong still worried about his child leaving home after the evening self-study.
"It smells so good, Comrade Wu, I give you a thumbs up, I'm so hungry!" She had been doing difficult questions for two and a half hours straight, and her brain's CPU was running in a row, which really consumed a lot of energy. Now she smelled the fragrance of the cake, which instantly aroused her hunger. Wu Tong put the cake to her lips and took a big bite. This is the taste.
Teacher Jin gave her little food from the stall, so when Comrade Wu picked her up, he would quietly feed her from time to time. Comrade Wu rode his bike, and Wu Tong sat on the back seat, leaning on her father's back, holding Comrade Wu's clothes with one hand to fix them, and eating the cake with the other hand. There was no greater happiness than this!

"Generally speaking, in a changing process, assuming there are two variables x and y,... the independent variable and the dependent variable... then it is a direct proportional function!..."
After finishing the summary of a large chapter on functions, Wu Tong paused and asked, "Brother, do you understand?"
These days, Wu Tong has allocated time for self-study of advanced mathematics and doing exercises at school, and he goes to Jin's house to give lectures to Jin Xin at noon.
I first spent two days explaining to Jinxin the concepts of sets, subsets, unions, intersections, complements, etc. in a clear and logical way. After Jinxin had mastered the concepts, I started to explain the concepts of functions in the next two days.
"I understand!" Jin Xin's eyes were filled with sudden enlightenment.
Jin Xin didn't understand before and had some broken links in his knowledge, but after Wu Tong's sorting and filling in the gaps, it has now become a long chain of complete understanding. Jin Xin feels that it cannot be clearer.
His admiration for his sister was like the endless flow of the Yellow River. Tongtong could easily pick up various knowledge points, write them down casually, and deduce detailed formulas, which made mathematics very interesting. If he had any problems, Tongtong could break down the knowledge points and make him understand them, whether it was the forward explanation or the backward explanation.
At this moment, he just felt that the pen in his hand was about to move, as if it wanted to transform into a forty-meter-long sword, chopping down the mountain of books and the sea of questions, and solving all the difficult problems.
Oh... OK, Wu Tong did not discourage Jin Xin's enthusiasm. He raised his hand and took out a stack of papers that he had prepared in advance and handed them to Jin Xin, "Then do these, little brother!"
The young man's current state is that he feels that he has mastered it all. He has gone through all the papers that she carefully selected, and then gone through the tempering of the senior high school entrance examinations and small tests, and squeezed out all the water. Only then did he truly master high school sets and functions.
The effect of her tutoring for the little brother will be reflected in the monthly exam for senior high school students tomorrow, and the results will be released next week.
"Good luck on tomorrow's exam, brother!" Wu Tong stretched out his hand and clenched his fist, bumped fists with Jin Xin like a buddy, and encouraged him with a smile.
"Give me five, of course!" Jin Xin nodded vigorously, otherwise he would be sorry for Tongtong's hard work!
