Among all of them, Mr. Sun had the biggest doubt in his heart, in fact, this problem was accidentally seen by him last night when he was flipping through the Olympiad materials, and people like him, who had spent his whole life teaching mathematics, also did it for half an hour to solve it, and when he opened the answer while holding a full page of scratch paper written by himself. Pen, fun, pavilion www. biquge。 info found out that the standard answer given in the data was only a secondary line, and a total of four steps were used to deduce the conclusion.

The reason why he wrote this question on the blackboard today, in addition to trying to test whether Tang Zhuojie, who is the best in mathematics in the class, can solve it unexpectedly, another reason is to frustrate the spirit of other students in the second (11th) class of high school, and they are about to enter the third year of high school.

Tang Zhuojie walked into a dead end in this question, and as expected by Mr. Sun, after he walked around the classroom a few times, he did not find any student who could solve it. But, Lin Zifeng...?

All the students watched as Lin Zifeng wrote out the first step, and then drew the first auxiliary line with the ruler on the podium.

However, these two actions alone caused a lot of discussion in the classroom.

"I'm going, how did the auxiliary line get there? Isn't this a mess?"

I thought he would really know how to solve it, but it turned out that it was just a headless fly bumping around. ”

"Hehe, I won't do this problem, if he can do it, I'll eat this math textbook. ”

“......”

In everyone's eyes, there is another pair that belongs to Yao Mengqi. When she saw Lin Zifeng draw the auxiliary line, her brows wrinkled at first, but then her heart suddenly beat rapidly, it turned out to be like this!

A student of Yao Mengqi's level, even if he encounters a problem that he can't do, as long as he knocks on the side, he will immediately be able to open up. Now that she had seen Lin Zifeng draw the auxiliary line, she naturally knew how to solve it next. Yao Mengqi's always indifferent eyes suddenly became very eager at this moment, looking at the back of Lin Zifeng who was writing, and sighed silently in his heart, it turns out that you are so powerful!

Old man Sun's body stiffened in place, a pair of cloudy eyes flashed with sharp light, he watched Lin Zifeng draw the same auxiliary line as the standard answer, and then wrote the same second step, the third step, until the final fourth step deduced the final answer!

Lin Zifeng finished writing, threw the chalk back to the podium, and then gently patted the chalk ash with both hands, and saw Tang Zhuojie, who was still frowning and contemplative next to him, and said unceremoniously, "Think slowly, don't peek." Then, in the attention of all his classmates, he walked back to his seat in a chic manner.

The classroom exploded, "No, it only took four steps to solve it?"

"Who would have thought of drawing auxiliary lines there, how long is his brain circuit?"

"I, why don't I understand, what the hell is this question..."

"Who said they wanted to eat books?"

......

Old man Sun's body trembled a little because of the excitement in his heart, he didn't think that this poor student could solve the problem from the beginning when he asked Lin Zifeng to solve the problem, let alone that his steps and methods of solving the problem would be exactly the same as the standard answer. Could it be that there is a mathematical genius in his class? Old man Sun glanced at Lin Zifeng with a complicated expression.

After a moment of amazement, calm returned to the classroom. Everyone paid attention to Tang Zhuojie, who was still standing on the podium to solve the problem, and now it seems that Tang Zhuojie's back is not only isolated, but also has a lot of embarrassment, because since his thinking was stuck, the chalk in his hand has been stiffly pressed on the blackboard, and he has not written down any strokes.

Under the self-esteem of being a good student and a representative of the mathematics class, Tang Zhuojie certainly would not look at Lin Zifeng's solution method regardless of face. What's more, when Lin Zifeng stepped down from the podium, he deliberately defeated him, how could he show weakness in front of the whole class?

And Tang Zhuojie is convinced that he is the strongest math student in the second (11th) class of high school, and Lin Zifeng can solve the problem, how can he not solve it!

Tang Zhuojie picked up the ruler and added an auxiliary line to the figure that had been drawn by him in a mess, but after adding this line, he found that his dead end had gone more thoroughly, and the chalk in his hand had to stop again.

After another two minutes and three minutes, some whispers began to sound in the classroom, and someone even shouted directly to the top of the podium, "If you can't do it, come down, don't delay everyone's time!"

The one who spoke was also a top student in the class, although mathematics was not as good as Tang Zhuojie, but other subjects were very top-notch. In the eyes of this kind of top student, every minute and second must be used to absorb new knowledge, how can a good math class be consumed by Tang Zhuojie like this.

But despite this, Tang Zhuojie still stood on the podium unmoved, if he gave up at this time, wouldn't it be obvious that he would be compared to Lin Zifeng? Tang Zhuojie would never allow such a thing to happen, let alone admit that he would lose to a poor student like Lin Zifeng.

Another half a minute passed in the increasingly embarrassing atmosphere, and the voices of discussion in the classroom became louder and louder, most of them were complaining about how Tang Zhuojie could waste everyone's time, and many people looked directly at Old Man Sun. Now it seems that it is impossible for Tang Zhuojie to take the initiative to step down, and only Old Man Sun can call him down.

In the past few minutes, Old Man Sun has been immersed in the shock brought to him by Lin Zifeng, and unconsciously felt the protests of his classmates getting louder and louder, so he coughed and said, "Tang Zhuojie, come down first, and think about it after class if you can't figure it out." ”

Tang Zhuojie, who had been on the podium, moved his body very reluctantly, he really couldn't figure it out now, he couldn't figure out that the image of a scholar he had always been a top student would be destroyed in Lin Zifeng's hands.

When he turned around, Tang Zhuojie's face was swollen and red, and he glared at Lin Zifeng fiercely with anger.

"Next, let's use Lin Zifeng's solution to talk about this problem..."

"Crazy, what's the situation, you can do this question?" Yang Wei turned his head, looking at his good buddy, but he had the feeling that he was looking at a stranger. In Yang Wei's eyes, Lin Zifeng, like himself, either gags in class, or sleeps with his head covered, and the two have comparable grades, and they have always maintained the top ten in the class, why did they suddenly become different today?

"What's so difficult about this", Lin Zifeng said casually, with a completely trivial expression on his face. In fact, in his heart, Lin Zifeng has realized that there is a certain force in his body that is constantly changing him, from the previous explosive power, reaction speed, to the current analytical ability, logical thinking...

Although he hasn't figured out where this power comes from, as long as he transforms himself in a better direction, he doesn't need to delve into the specific reasons, just enjoy the new changes in his body.

After the math class, Lin Zifeng was called to the office by Old Man Sun alone. Could it be that the old man is still worried about me sleeping in class? Lin Zifeng thought silently in his heart, and unconsciously walked to the door of the office.

"Report", Lin Zifeng called at the door.

Old man Sun raised his head when he heard the voice, waved his hand at Lin Zifeng, and motioned for him to come in.

Lin Zifeng saw that Old Man Sun's face was not angry, so he stepped in with peace of mind, "Teacher Sun, is there something wrong?"

Old man Sun took off the reading glasses on the bridge of his nose, looked at Lin Zifeng with unpredictable eyes, and asked, "Did you come up with today's question?"

Lin Zifeng thought something was wrong, but he didn't expect Old Man Sun to still be entangled in the three-dimensional geometry in class, and nodded and replied, "I came up with it." ”

Although he received an affirmative answer, Old Man Sun still had an expression of disbelief on his face, "You really haven't done this question before?" Or, haven't you seen the standard answer to this question?" In Old Man Sun's opinion, it is impossible for a student like Lin Zifeng to have the ability to solve this problem, he thought about it for a long time, and the only reasonable explanation that came up with was that Lin Zifeng had already seen the standard answer to this question before.

Hearing these two questions, Lin Zifeng felt a chill in his heart, and a sneer appeared on his face, it turned out that the old man was doubting his ability to solve problems. Even if he solved this problem in front of everyone, and even thought about it for five minutes before solving it, Old Man Sun would not believe that he did it himself.

"That's right, I've read the answer, can I go now?" Lin Zifeng said coldly, he had long seen through Old Man Sun, a teacher who looked at students with colored glasses, in their eyes, good students and bad students were basically two creatures. Since he belongs to the category of poor students, why should he embarrass Old Man Sun?

Without waiting for Old Man Sun to answer, Lin Zifeng walked out of the office by himself, what kind of strength does he have now Lin Zifeng knew in his heart that he didn't bother to prove it to anyone.

After the last chemistry class, Lin Zifeng, Yang Wei and Lu Guang packed their schoolbags and were about to walk out of the classroom, when two people in basketball uniforms suddenly walked over with one hand holding a basketball.

"Is that just the three of them?" said the taller one, a look of disgust on his face.

Lin Zifeng looked up, the two people who came over were all sports students in the class, the slightly taller person holding the basketball in his hand was called Gao Hao, and the other person next to him was called Zou Hongyu, who was the only two students in the second (11th) class who were more than 1.8 meters tall.

"Yes, the other three are them", Zou Hongyu said, although his height is shorter than Gao Hao, but his body is much stronger, and he knows that he is also a sportsman at a glance.

"The three of you bring the ball suit tomorrow, don't drag Lao Tzu back!" Gao Hao said fiercely, and after speaking, he deliberately slammed the basketball in his hand to the ground, and with a bang, the height of the blue ball rebounded alone exceeded Lu Guang's head!
