The two came to the pavilion in the center of the courtyard, where there was a stone table and four stone benches.

Su Xuechen and Lu Menglin sat down face-to-face and took out the textbooks and workbooks in their schoolbags.

"This place is really good!" Lu Menglin couldn't help but let out a heartfelt exclamation.

Su Xuechen smiled slightly and opened the textbook.

At that moment, the sound of footsteps stepping over the cobblestones was heard on the right side of the two.

A young lady waitress in a sky blue skirt uniform came lightly with a tray.

The waitress lady who looked like she was more than eight points in figure seemed to be familiar with Su Xuechen, and greeted her with a smile while skillfully placing the teapot and two teacups in front of the two of them.

"It's rare for Xiao Su to bring a friend over today? I'll send a fruit bowl later." The waitress smiled.

Su Xuechen's face seemed to be slightly redder than usual, and he said in a low voice: "It's a classmate, I brought him over for tutoring." ”

The waitress didn't talk much, and left with a smile.

Lu Menglin had a flash of inspiration in his mind, and finally remembered what kind of place this was.

In his memories of his youth, he heard an unverifiable legend that there was a special guest house for senior cadres in the factory, which was never open to the public and was specially used to entertain superior leaders.

Ordinary factory workers only hear his name, and they don't know where it is, let alone younger children like Lu Menglin.

Could it be that this small courtyard hidden deep in the shade of the trees is the legendary high-level guest house?

Lu Menglin couldn't help but start to wonder about Su Xuechen's family background, she is so familiar with the waiters here, she should come often, but everyone knows that her parents are not the main leaders in the factory, why is this?

However, after all, this is someone's private matter, she doesn't take the initiative to say it, and of course Lu Menglin won't ask more.

Soon, Lu Menglin overcame his curiosity about the environment and began to devote himself to the process of making up classes.

His method is very simple, that is, to do questions according to the progress of the textbook, do typical questions, and ask Su Xuechen for advice when he encounters questions that he can't do.

Because Lu Menglin knows very well that all he needs is to make up for his shortcomings, and he doesn't expect to get a high score in mathematics at all, as long as he understands the basic question types and the formulas and theorems that match them, everything will be fine if he can get an average score.

Therefore, when Lu Menglin got the question, he thought about it first, and if he couldn't figure it out, he directly asked Su Xuechen for advice.

Su Xuechen was very serious about helping Lu Menglin solve the problem, and she was a little surprised at first, because the questions Lu Menglin did were too simple, all of them were only at the junior high school level, which was easy for her, and she could write the answer at a glance.

However, she soon discovered that Lu Menglin was not simply solving the problem, but understanding and familiarizing herself with the formula in the process of solving the problem.

"What's the point of doing this?" Su Xuechen looked at the serious boy in front of him, and couldn't help but fall into deep thought.

Someone once said that when a girl starts to be curious about a certain boy, it is often the beginning of a liking feeling.

However, Lu Menglin's focus at the moment is obviously not here, he is really thinking hard, racking his brains, trying to understand those difficult formulas in the process of solving the problem.

"This question, please help me see again, what kind of trick is this auxiliary line, why do you use it like this?" Lu Menglin frowned and grinned.

Su Xuechen took the question, looked at it, and said with a smile: "If there is an angular equinox in the question, you can make perpendicular lines to both sides; the line segment is bisector vertically, leading to connect the lines at both ends, and the two midpoints on the sides of the triangle are connected to form a median line; there is a middle line in the triangle, and the extension of the middle line is doubled...... If you memorize this mantra, you won't be afraid of auxiliary lines in the future. ”

Listening to the crisp voice of the girl beside him like a silver bell, Lu Menglin nodded again and again.

The auxiliary line of all evils, under Su Xuechen's clear recitation, seemed to become less annoying.

Lu Menglin grinned, smiled heartily, and continued to bow his head to do the question.

The afternoon sun shines through the shade of the trees, and the spots of light reflect on the young man's angular side face and broad shoulders, as if he is draped in a pale gold battle suit.

Su Xuechen looked at the boy who had been in the same class with him for two years, and suddenly felt as if he had just met him.

"This guy is sometimes quite handsome!" the girl thought to herself.

Originally, she was worried that Lu Menglin would be distracted when she tutored with her, but she didn't expect that it was she who couldn't give up.

Su Xuechen frowned slightly, shook her head slightly, and quickly drove those distracting thoughts out of her mind.

Because she knows very well that she will not be interested in men at this stage, at most she will only appreciate the excellent qualities of some people.

Looking at the guy in front of her who was already focused on the math problem, she took a deep breath and forced herself to turn her attention to the book.

At this moment, Lu Menglin had completely entered the state, and he was fascinated. Because this may be the first time in his life that he has found joy in solving mathematical problems.

Those stubborn and cunning questions are like a mess of threads, entangled and messy, and the mathematical formulas I have just learned are like sharp scissors, easily cutting through the threads, reaching the heart, peeling off the cocoon, and solving the mystery accurately.

Looking at this big boy who sometimes had a sad face, sometimes talked to himself, and smiled knowingly, Su Xuechen's mood suddenly became very good at this time.

In fact, she even envied the guy in front of her, envying him for being able to feel happy from the bottom of his heart!

This is an emotion that I haven't experienced for a long time as a top student!

Seeing that Lu Menglin gained so much joy from solving those simple junior high school math problems, Su Xuechen was even a little jealous.

"What, do you feel happy?" Su Xuechen couldn't help but ask.

Lu Menglin turned the pencil in his hand and nodded very hard.

He finally experienced what it was like to be enlightened, and if he could keep it in this state, he would never be able to stop himself anymore if he believed that mathematics was an obstacle to his mind.

"Do you think these questions have become much easier?" asked Su Xuechen with a smile.

Lu Menglin nodded again, and suddenly thought of a sentence that he saw in later generations, and couldn't help but blurt out: "If people don't believe that mathematics is simple, it's just because they don't realize the complexity of life." ”

This is what the great mathematician von Neumann of the last century said, and Lu Menglin saw it in a TV series in later generations.

Just like the joy in front of him, if he didn't have the life experience of later generations and endured all the hardships in the rolling red dust, how could Lu Menglin sink his heart and discover the joy of mathematics and even learning.

Su Xuechen didn't expect to hear such deep words from the mouth of Lu Menglin, a boy of the same age, and couldn't help but be stunned.

With her intelligence, she can naturally taste the life philosophy contained in this sentence, but she never imagined that Lu Menglin would have such a state of life, and she felt that the boy in front of her was a little different.

At this time, Lu Menglin raised his head, rubbed his slightly sour wrist, and fell on the girl opposite.

The ancients did not deceive me!

After working hard to solve the problem for a long time, and then looking up at the beautiful women, it is really boring!

Looking at the pure and beautiful Su Xuejian, it is like eating ice cream for the eyes, which is really pleasing to the eye.

Lu Menglin didn't even blink his eyes, his eyes were as pure as crystal, there were no distractions, only appreciation and liking.

"What are you looking at?" Su Xuechen was a little uncomfortable by him, and glared.
