Lin Zhixia was full of energy and full of confidence. She held the receiver of the landline and spoke firmly: "Jiang Yubai, I will bring the gold medal in this competition back for you to play."

Jiang Yubai followed her meaning and echoed: "I have never played it before, the gold medal in the National Mathematics Olympiad."

"Wait for me to come back," Lin Zhixia made an agreement with him, "I'll invite you to have dinner in the school cafeteria."

Jiang Yubai didn't like the school cafeteria very much. But he was unwilling to admit that he was a picky person. He in turn invited Lin Zhixia: "I'll invite you to my house for dinner."

Lin Zhixia suddenly remembered the "museum pass" that Jiang Yubai gave her. She asked with great anticipation: "When can I go to your house?"

Jiang Yubai replied: "When you have time."

Lin Zhixia jumped in place: "Okay, Jiang Jubai, we'll see you next month."

Jiang Yubai responded: "See you next month."

Before Lin Zhixia finished the call, she said by the way: "I will call you on time at 6 o'clock tomorrow evening. Is it OK?"

"Yes." Jiang Yubai agreed to her concisely.

The atmosphere on the dining table was quite quiet. Jiang Yubai put his phone into his pocket of clothes and picked up a braised eel roll with chopsticks. The eel roll contained cucumbers, eels, avocados, and a circle of seaweed on the outside, with a layer of white sesame seeds on the surface. He felt that Lin Zhixia would like this dish. He was already secretly planning a future lunch. He hoped that Lin Zhixia would have a good time at his house.

The uncle suddenly asked him: "Jiang Yubai, have you called Lin Zhixia?"

Jiang Yubai admitted: "Yes."

He waited for almost two days before receiving a call from Lin Zhixia. He pressed the answer button without hesitation, almost forgot that his parents and uncle were still beside him. He carefully considered the call just now, thinking that his words were not wrong, which was in line with his parents' usual requirements.

Mom smiled and said, "You have a good relationship with Lin Zhixia."

The uncle picked up the transparent goblet: "Sister-in-law, listen to me, I have met Lin Zhixia. Lin Zhixia's IQ is as high as 174, she is really not an ordinary girl. We Xiaojiang makes friends with her... Just like I date young masters in the classical music industry, we maintain a pure and flawless relationship and a relationship that promotes each other. Xiaojiang is willing to ask others modestly, and it is probably what I learned from me."

Dad asked back: "Is that true?"

The uncle put down his wine glass and changed his words on the spot: "It is more likely that Xiao Jiang understood it himself."

Dad leaned slightly on the back of the chair and looked at Jiang Yubai quietly. After a while, Dad said warmly: "You and Lin Zhixia are good friends, and we are happy to see you get along well with your classmates..."

Dad wrapped his fingers around the mouth of the wine glass and stopped halfway through his words - this situation is rare. He always educated his son in an orderly manner. Tonight, he looked at his wife sideways.

Jiang Yubai's mother took on this important task. Her mother wiped the corners of her mouth with a napkin and reminded implicitly: "Jiang Yubai, you are eleven years old. In a few months, you will be twelve years old and a little man. If you are friends with a little girl, you must understand that the genders of you two are different. You must respect her and grasp the boundaries and standards."

Jiang Jubai nodded.

The uncle tapped the wine glass with his fingertips: "Yes, grasp the boundaries, Xiao Jiang."

Jiang Yubai answered the conversation very readily: "No problem."

"That's good," said Mom, "My parents believe in you."

The guidance of his parents and uncle inspired Jiang Yubai's gender awareness. Although he used "male standards" to demand himself since he was a child, he often ignored the "boundary issue between boys and girls". Fortunately, he and Lin Zhixia have always maintained a deep friendship, respected and urged each other, and never offended each other - he has completely forgotten how his self-esteem was destroyed by Lin Zhixia when he was nine years old.

At 8:30 that night, Jiang Yubai fell asleep calmly.

At the same time, Lin Zhixia turned off the lights and went to bed.

Lin Zhixia hugged the little penguin with her left hand, lifted the quilt with her right hand, and lay in the soft bed. She silently recited Jiang Jubai's words - the universe is black and she is not afraid of the universe. She believes that her fear comes from the unknown. For example, "dark matter" is an invisible matter in astrophysics theory and is widely distributed in space. If "dark matter" really exists and Lin Zhixia can still see it clearly, then the universe should be another grand and dazzling scene in her eyes.

Darkness and light are relative concepts. As long as Lin Zhixia has light in her heart, the night is bright when she can’t see her fingers.

Lin Zhixia no longer retreated and was no longer timid. She lay flat on the bed, revealing her whole face, just like sleeping at home, sleeping peacefully until the next morning.

At 8 o'clock in the morning, the National Mathematics Olympiad officially began.

The National Mathematics Olympiad has an alias called "National Mathematics Winter Camp for Middle School Students".

Lin Zhixia proudly declared to her parents that she wanted to participate in the National Mathematics Olympiad. In front of outsiders, she humbly stated that she had signed up for a winter camp.

The winter camp questions are very well-designed. The first question is an algebraic problem. It is known that a sequence of positive integers that are not subtracted. The m sub-columns contain n different positive integers, which requires the lower bound of the summing formula of the sequence. Lin Zhixia started to prove another proposition, narrowed the scope, applied it to the summing formula limited to the question, and quickly solved this problem.

Next, she encountered problems with plane geometry and combination.

Lin Zhixia didn't delay a minute and wrote down her thinking process on the answer sheet.

The so-called "Mathematical Olympiad" is actually just doing questions in the exam room. The International Olympic Mathematics Competition is to do questions with contestants all over the world. There is no essential difference between competition and exam, and Lin Zhixia has no pressure.

The mathematics competition is divided into two days, and three questions are tested every day, with 21 points for each question. After Lin Zhixia finished the test paper, she was inspired by the questions on the paper. She sat in the classroom, her mind full of Hua Luogeng's "Theory of the Pure Primitive Numbers".

When she walked out of the examination room and met with the provincial team leader again. The teacher asked her how she did the exam, she subconsciously blurted out: "Abel Group and Exchange Half Group."

The teacher was stunned.

The other students from the provincial team were also stunned.

Lin Zhixia hurriedly said, "I did a good job in the exam."

Most of the players in the provincial team are boys, and girls only account for a small part. Looking at the entire winter camp, the number of girls is not the advantage. On the international Olympic battlefield over the years, national teams in various countries are mainly male players. Perhaps because of this reason, Lin Zhixia has attracted much attention in the competition field.

By the way, there is another reason - she is too young.

She expressed her opinion carefully: "The questions in this test paper are very exciting, especially the combination question, which is ingeniously constructed. Starting from the principle of the drawer, without going beyond the outline, it has trained its thinking."

But a boy next to her said, "There is nothing to talk about that question."

Lin Zhixia looked up at him.

This boy is the senior in the high school competition class of Provincial No. 1 Middle School, named Guan Tong.

Senior Guan Tong is seventeen years old this year and is in his third year of high school and has already won the recommended place. He is considered a top student in the high school competition class. His goal is to be a gold medal in the International Mathematics Olympiad, and this year is his last chance to win the championship.

Lin Zhixia believes that she and Guan Tong have a generation gap. Guan Tong often refutes her views - no matter which aspect of her opinion, Guan Tong will immediately put forward different opinions.

In contrast, another senior sister named Luo Ying in the provincial team has a much better attitude than Guan Tong.

Luo Ying is a senior in the high school second-year competition class of Provincial No. 1 Middle School. Lin Zhixia met Luo Ying at the 2005 high school club welcome meeting. She remembered that at that time, senior Luo Ying was still in the high school training class. Later, senior sister transferred to the competition class. It is said that senior sister was very hard-working. She got up early in the morning and went to bed in the early morning. She worked hard for a whole year and a half before gaining a foothold in the competition class.

Lin Zhixia admires such a person. She is full of respect for senior Luo Ying. She often follows Luo Ying behind her and happily calls her: "Senior sister, senior sister."

Luo Ying is also very protective of Lin Zhixia.

When Luo Ying heard Guan Tong's words, she immediately retorted: "There is nothing to talk about in the question? Can you give me a similar question?"

Guan Tong smiled "haha". He wiped his face in a hurry, his eyes staying on Luo Ying's face. It was cold and the wind was cold at the end of January. He and Luo Ying looked at each other for ten seconds, and a thin layer of sweat broke out in his heart. The sweat eroded his chest. He raised his head and said, "Luo Ying..."

Luo Ying pretended not to hear him.

In the third year of high school, Guan Tong is considered a sensible figure. He is tall and thin, has a good appearance, has excellent grades, has been successful in the admission, and has entered the mathematics department of a top university with half a foot. How open and bright his future is!

However, when he talked to Luo Ying, Luo Ying always ignored him.

Luo Ying only said to Lin Zhixia: "Let's go to the fruit store at the entrance of the hotel to buy strawberries."

Lin Zhixia's eyes lit up: "Strawberry? OK!"

Luo Ying murmured to herself: "Girls are much cuter than boys."

Lin Zhixia didn't hear her clearly. Lin Zhixia asked her: "Senior sister, what were you talking about just now?"

Luo Ying smiled: "I didn't say anything."

Luo Ying stretched out a hand to Lin Zhixia, and Lin Zhixia immediately held her. Luo Ying seemed to have a well-behaved and sensible sister suddenly. She is an only child at home, and her parents have only one daughter. And these days, she suddenly realized that it seemed good to have a sister at home. The friendship between sisters is deeper and easier to understand each other.

The examination phase of the National Olympic Mathematics Competition has ended.

All the students in the provincial team relaxed temporarily. The hotel they stayed at had their own chess and card room, and the team leader allowed everyone to entertain appropriately, and played chess and cards in the chess and card room, which was harmless.

Guan Tong once again invited Luo Ying. He asked Luo Ying to go to the chess and card room and play a game of chess with him.

While he was talking to Luo Ying, Lin Zhixia stood beside them with a bag of strawberries.

Lin Zhixia opened a small hole in the plastic bag and quietly peeked at the strawberries. The strawberries on the market in winter are large in size, moderately soft and hard, and look very sweet.

This whole bag of strawberries was bought by Lin Zhixia. She used the 500 yuan scholarship she had privately kept. She planned to wash the strawberries and share them with her senior sister.

At this moment, the senior sister suddenly said, "I am sixteen years old, you are seventeen years old. What is there to talk about in this age group? I can't control my agitation during puberty, and I'm too boring."

Guan Tong stuttered in front of Luo Ying, her face pale as if it was a persimmon beaten by Qiu Frost.

After all, he is still a shameless person. Luo Ying said this to this point, and he could no longer continue to express his affection for her. His obscure confession had been ruthlessly exposed by Luo Ying. His fragile boy's heart was like a piece of broken glass, and the glass shards fell all over the ground.

Guan Tong's throat felt sore and her eyes were red.

A man doesn’t cry easily, but he hasn’t reached the sad place.

Guan Tong wants to say goodbye to Luo Ying.

In 2006, Taiwanese idol dramas became popular throughout Asia. Guan Tong also watched a little while when he was free. He decided to imitate the clips in idol dramas, just called the latter word in the name "Luo Ying", which seemed intimate.

Guan Tong raised his arm, wiped his face, and said in a low voice: "Sakura..."

Lin Zhixia continued: "Yeah."

Guan Tong was stunned and said, "Sakura..."

Lin Zhixia said again: "Yeah."

Guan Tong was stiff all over and stood there.

Lin Zhixia's voice-over made Guan Tong's carefully prepared affectionate call all become "受受" wailing.

His masculinity was gone, all gone.

Lin Zhixia comforted him: "Senior Guan Tong, although you were rejected by Senior Luo Ying, you are still an excellent player in the provincial team and have the hope of participating in the International Olympics. Don't whine anymore, everyone will encounter setbacks. We must overcome setbacks and strive to achieve higher goals."

Guan Tong calmed down and said coldly: "Lin Zhixia, you have a high score in the provincial team's high league competition, which is nothing great. The Beijing team and the Shanghai team are the two strongest teams in the country. Your level is not as good as the first team in Beijing, and you can only go to the second team at most..."
