"In this problem, we know that the zero point of y=f(x) is x=35..."

The warm winter day is slanted into the classroom through the window, warm and comfortable. Pen ~ fun ~ Pavilion www.biquge.info Wei Yi's head arched on his arm, as if he had found a more comfortable posture, and fell asleep again.

On the podium, the head teacher Chen Yi was still commenting on the exercises assigned the night before, but the warm classroom and boring explanations made many people drowsy and unwilling to listen.

Qi Ye in the front row of Wei Yi is 182 tall, and he always looks up and does not squint during class, he looks diligent, studious, rigorous and motivated, and can be called the honest appearance of the class teacher's intimate little padded jacket, with the cover of him and Li Jingfeng, plus Wei Yi was already sitting in the last row of the first group against the wall, which is the most corner area, so he naturally slept soundly.

After a short time, the bell rang for the end of class, and the corridor resumed to be noisy, with people coming and going, and laughter and laughter. However, Wei Yi didn't know if he didn't sleep well last night or what, and he still slept very soundly at this time.

Suddenly, the window next to them was opened, Zhao Zhi's head stuck in, and Li Jingfeng said, "Why did you come down today?" ”

He saw Ye Baiming behind Zhao Zhi again, and he was even more surprised in his heart.

Zhao Zhi and Ye Baiming are both in class 15, and the only class on the third floor in the first year of high school - Zhao Zhi is just that, this guy goes to various classes every day, but Ye Baiming has never been to their fourth class.

Zhao Zhi looked down and saw that Wei Yi was sleeping soundly, so he hurriedly lowered his voice and said, "Do you know? The student council is going to organize a basketball game! ”

Li Jingfeng was stunned: "I haven't heard of it, how do you know?" ”

Zhao Zhi smiled: "Did you forget? Chen Ling in my class is from the student union! She said that this was decided by President Ji Xueli, don't say it, this is a good opportunity to exercise our strength! ”

"Is it class-based?" Li Jingfeng asked.

"No, it's said that it's based on the year, one team in each year, a total of three teams in the ring."

Li Jingfeng's eyes lit up, and he said with a smile: "Then how do you think that our strength in the first year of high school is not bad!" ”

"That's why I'm here to find you and Wei Yi!" Zhao Zhi said excitedly, "The four of us will team up, and it will be enough to find a little front!" ”

"When does it start?"

"It's not decided yet, President Ji Xueli said that it is tentatively scheduled for the school anniversary, that is, the Wednesday after the final, Chen Ling also asked me when the league will be played, and I said that there are still two games to play."

Li Jingfeng smiled: "You have confidence." ”

The two chatted, Ye Baiming stood aside silently, his eyes silently looked at Wei Yi's sleeping side face, his eyelids raised, and said abruptly: "How long has he been asleep?" ”

"Uh..."Li Jingfeng said subconsciously, "I was sleeping after finishing my homework in the last class, and I saw that he had yawned again and again in the morning..."

"Has he been like this all these days?"

Li Jingfeng couldn't help but glance at Ye Baiming more, as if asking: Why do you suddenly care so much about him?

However, he still nodded and said, "It should have been like this since the day before yesterday..."

Day before yesterday......

Tuesday?

Ye Baiming seemed to have an understanding, nodded slowly, and stopped talking.

…

…

"Dad! I'm serious, that guy I think you have to meet! ”

The voice on the other end of the phone was a little vague, but it could be vaguely distinguished: "Can you reach 5S?" If not, don't waste my time! ”

Guo Xuerao hurriedly said: "It's here!" His speed, explosiveness, and bounce have all reached S! ”

"What about physical strength?"

"There is also an A+ physical strength..."Guo Xuerao said with a pout, "He is only sixteen years old, and it is rare to have A+ physical strength!" ”

Guo Yanzheng yawned sleepily, shook his head and said: "Don't let me return to China without 5S, I have so many good seedlings at hand, you can't tell me to drop the watermelon and pick up sesame seeds." ”

"But... That Gongliang of yours doesn't even have an A+, and his physical fitness is so poor! You still don't value it that much! ”

"Can it be the same? His diligence is his greatest strength, and his skill is so delicate that no one can match it! ”

"But Wei Yi, he is Uncle Wei's son! You don't have it at all..."Guo Xuerao couldn't go on...

"......" Guo Yanzheng was silent for a moment, then sighed leisurely, and finally relaxed: "Then let's wait for them to enter the national competition, if I have time, ......"

"Really?!" Guo Xuerao said happily, "You have to count when you speak!" ”

"Did you call in the middle of the night just to talk about this?" Guo Yanzheng said angrily.

Guo Xuerao smiled dryly: "Didn't I forget the jet lag..."

"I've never seen you speak for a person like that, haven't you just met him?"

"Can it be the same? After all, he is Uncle Wei's son, and besides, Sister Wei Yu and Uncle Su have begged me so much... Originally, according to my meaning, I wanted to train Wei Yi by myself, and then defeat your Gongliang! Hum! Look where your old face goes! ”

Guo Yanzheng yawned again, and said with a sleepy smile: "This bet contract sounds good, I'm very interested, haha... Ok ok... You haven't gotten out of school yet, have you?! Hurry up and go to class! ”

Guo Xuerao's wish was fulfilled, and she hung up the phone happily, she was in a good mood, humming a song and walking to the class.

As soon as she reached the staircase, the cheerful tone in her mouth suddenly stuck in her throat, and she couldn't pronounce half a syllable! She froze in astonishment, her face pale as paper, her form shaky as if she had been struck hard.

Two familiar backs suddenly broke into Guo Xuerao's field of vision, and the hands of the two clasped together, like a sharp sword, instantly pierced her heart with blood!

Luo Honghui and Zhang Anqi, who were unconscious, talked and laughed, turned the stairs with a happy face, and gradually disappeared from her sight.

And she burst into tears in an instant...

…

…

"Jiahui! Hey? What are you looking at? ”

Shu Ting, who went to the student union to get the documents, ran down the stairs lightly, and saw Zhou Jiahui waiting below looking at the two figures in the distance with a distracted expression, and couldn't help but be surprised.

"Huh? You got it so quickly? ”

"yes!" Shu Ting raised the report in her hand, and their secretariat was dealing with these things every day.

"What were you just looking at?" Shu Ting casually stuffed the report into her schoolbag, and followed Zhou Jiahui's gaze, "Huh? Isn't that the president and Senior Lu Ning? ”

Zhou Jiahui trembled, and said in disbelief: "You said that figure... Is it the president? ”

"Otherwise... With such a charming and tall back, and that long black shawl hair, who else can walk with Senior Lu Ning, who else can there be besides the president? Shu Ting smiled and said, "But won't the president stay and work overtime at night?" And Senior Lu Ning also wants to train in the school team, why did he leave so early today? ”

Since Lu Ning joined the school team, Ji Xueli's overtime hours have also been much more regular, she had dinner in the cafeteria after school, and then she handled things or studied in the student union office, and finally "met by chance" with Lu Ning, and the husband and wife both returned home - of course, counting the little light bulb of Lu Yan...

However, today because of Coach Su Hanping's trouble, the school team suspended training for a day, so the president who is used to singing with his wife also said "coincidentally" that there is nothing to do today, I will go to the student union to get some documents and go back together!

- Really, do you two dare to act more obviously? Why are you not directly together after all this!!

(A group of readers slapped the table and were furious: we want to know too!!) ）

"Sure enough, Ning Li is the warmest to Shenma!" Shu Ting, who was heartbroken for the two of them, held her cheeks and said shyly with stars in her eyes.

"You mean...?" Zhou Jiahui felt that her voice was trembling a little...

"It's not what you think!" Shu Ting smiled, "They are not boyfriend and girlfriend!" ”

"It's... Is it..."Zhou Jiahui lowered her head, not knowing what she was thinking...

Shu Ting was unaware of the strangeness of her friends, she looked at the backs of Senior Lu Ning and President Ji Xueli walking side by side, and couldn't help but sigh: "Ah~ They are really a good match, they really want people to match their enviable pair all the time!" ”

"That's... President... Do you also like Senior Lu Ning? ”

"Hmm... I like it very much..."Shu Ting smiled, "Although the president always looks cold in front of people, the people on the executive committee know that as long as the president is in front of Senior Lu Ning, he will be like a different person, but gentle!" And Senior Lu Ning is also very good to the president, always protecting her in secret. But... Sometimes it's really hard to understand, why don't they express it clearly when they have such deep feelings? ”

Shu Ting's words Zhou Jiahui couldn't listen to them at all, she only felt cold hands and feet at the moment, and her mind was blank...

Originally... It turns out that the senior's sweetheart... It's the president!

Actually... It's the president...

Her slender white fists clenched...

…

…

"So you didn't plan to ask us for help last time about Zhou Han?" Ji Xueli glared at Lu Ning dissatisfied.

The dim sunset shone on Lu Ning Yingting's side face, he smiled and said, "It was a temporary decision, plus it's a weekend, I can't let you forcibly pull all the people in the student union to the school!" ”

"Even if that's the case, you should tell me." Ji Xueli complained, "After all, it's always good to have one more person to help." ”

"Haha... I forgot..."Lu Ning laughed dryly twice - I can't say that I deliberately didn't tell you because I didn't want my wife to squeeze into a room with those hungry single dogs...

"By the way, didn't Auntie go on a business trip in the morning, what are you going to do for dinner?" Lu Ning remembered that when she went out in the morning, she happened to see Ji Xueli's mother dragging her suitcase, and only after saying hello did she know that she was going on a business trip.

As Ji Xueli's neighbor, he knew that Ji Xueli's father was an engineer, and it was common for him to be not at home.

"Cook it yourself... Or else? ”

Lu Ning looked around and said with a smile: "Then I'll invite you to a big meal, and we'll go together after the Yan'er club activities are over for a while!" ”

"Feast!?" Ji Xueli was surprised, "Where did you get the money?" Aren't uncles and aunts controlling your pocket money very tightly? ”

"But it can't be helped, who told me that the cash cow is here again!" He smiled charmingly and pointed forward.

Ji Xueli followed Lu Ning's gaze and looked forward, only to see several people gathered on the side of the road, watching a chess endgame on the ground.

Seeing this familiar picture, Ji Xueli couldn't help but laugh, she had seen a lot of this kind of stall, as long as Lu Ning had no money to spend when she was a child, she would go to these "cash cows".

"So you're trying to get back to your old business?" Ji Xueli couldn't help but smile, and her beautiful eyes glanced at him with disgust.

"It should be a newcomer, I haven't seen that bureau master, but it's just right, hehe~"

Seeing his treacherous expression when the big bad wolf saw the little white sheep, Ji Xueli shook her head amusedly, and followed curiously...

"Look at my Lao Zhou's game, the three pawns are handsome, the five soldiers are forcing the palace, the cars and cannons are uneven, and there are no horses in each other's directions, who wants to give it a try? Fifty at a time, two hundred to break the game, watch the chess without saying a word, and have no regrets about the chess! The player squatted in front of the chess game and shouted hard, and the crowd around him was talking, and it didn't take long to see a middle-aged man with bronze skin coming off the court to take over the game.

"Okay, fifty dollars, red first, distinguished guests, please-"

The man didn't twist either, when he took the first step to shoot a flat six, this bureau owner called Lao Zhou obviously had a case, followed by a step car 4 flat 6...

"Hmm..." Lu Ning, who was standing on the sidelines, stared at the chess game for a few moments, then rubbed Ji Xueli's hair and laughed softly, "Snow Seal Plum Blossom, girl, your dinner has arrived!" ”

Although Lu Ning's voice was very soft, Lao Zhou in the crowd still heard it vaguely, especially the four words of snow seal plum blossom, he had a spectrum in his heart, so naturally he would not hear it wrong, and his face immediately changed greatly, and he glanced at the tall and thin boy in shock.

"Then I just need to think about what I'm going to eat tonight?" Obviously, it is not the first time that our president has eaten and drunk with her husband, and she has absolute confidence in Lu Ning's ability, so she teased with a relaxed face.

After a few strokes, the man who took over the game became sluggish, barely struggled a few steps, and finally disarmed and surrendered.

At this time, Lu Ning squeezed into the crowd, squatted down and said with a smile: "I'll have a game!" ”

Lao Zhou glanced at Lu Ning and waved his hand: "I'm going to change the game, now start a hundred and one times, do you still want to try?" ”

Lu Ning was stunned, he obviously didn't expect this game master to come to this move, for him, it didn't matter if the game changed, after all, he liked chess since he was a child, and he had seen nearly a thousand endgames. But this hundred times, he was a little distressed - he only had more than sixty dollars in his pocket...

In fact, Lao Zhou's heart is also bottomless, he can see that this young man is a person who knows chess, and he can recognize the snow seal plum blossom at a glance, he doesn't believe that he will be a layman. But he couldn't directly refuse the challenge of others, so he had to raise the bar and threaten to change the situation to make him retreat.

Seeing that Lu Ning's face was difficult, Lao Zhou was a little settled in his heart, and only said that he had already retreated, so he hit the railway while it was hot: "Young man, forgive me for talking too much, originally, I set up a stall here to do business, and I hope that the applicant will continue to make money, but it can be seen that you are still a student, and you eat your parents' parents, so why bother to join in this fun?" Can your chess skills be as powerful as those uncles and elders around you? In the end, it's not for nothing, my old Zhou? As the old saying goes, a gentleman loves money and takes it in a good way, and I am confident that I still disdain to earn children's money, so young man, let's hurry home, Pleasant Goat is about to start! ”

He said this call affectionately, and indirectly praised the surrounding onlookers, which naturally won everyone's approval.

"Yes, young man, let's just take a look, this kind of thing doesn't mean just joining in the fun!"

"That's right, it's a few dozen dollars, even if you buy something to eat, it's better than throwing it into a pit!"

Lao Zhou's call is quite like a thing to other people's ears, but Ji Xueli is not happy - dare to say that my Lu Ning's chess skills are not good? Do you want to find death?

No one knows Lu Ning better than her, she knows that he will show hesitation, it can't be because he has no bottom in his heart!

"Humph!" Ji Xueli squatted down beside Lu Ning, took out the only more than eighty yuan in his pocket, and stuffed it into his hand: "One hundred is one hundred!" ”

Lu Ning glanced at Ji Xueli in surprise, and saw that her pretty face was tense, and he couldn't help laughing in his heart, he knew that this girl's stubbornness had come up again.

"Are you really coming?"

"Well, let's get started!" Lu Ning smiled, with a calm face...

"Wait..."Ji Xueli stopped Lao Zhou's movements, and said with a cold face, "Since it is one hundred at a time, will the bounty also be doubled?" ”

Old Monday's face changed when he heard it, and the bounty was doubled? Four hundred in one game?!

At this time, a group of onlookers who ate melons and watched the play also echoed: "What this little girl said is reasonable!" ”

"Yes, since it's doubled, it's all doubled!"

"People's young men and little girls, you old Zhou also let young people..."

Lao Zhou, who was difficult to ride a tiger, had to grit his teeth: "Okay, four hundred is four hundred!" ”

He picked up the pieces on the board, and after a while, he re-established a new game.

"Seven Star Gathering?" Seeing this, Lu Ning shook his head and said with a wry smile, "When you leave, there are seven sons on each side, and there are only seven sons left in total, this game is indeed one of the most difficult endgames, but it is also one of the most thoroughly studied endgames, you better change to a less popular one." ”

"Uh..." Lao Zhou blushed, but he didn't dare to be strong, so he had to pick up the chess pieces and put on a game.

The two pawns arrived together, the three armies broke into battle, the generals were displaced, and there was no way out.

Lu Ning just wanted to remind him to change the game again, but Ji Xueli pinched his thigh quietly and stopped him alive.

"Okay, let's get started..."

After paying a hundred yuan, Lu Ning took a step directly and drove six into two, and Lao Zhou's face suddenly turned to ashes...
