On January 13, 2005, the temperature was low and the wind was blew, and a snow fell on the sky, covering the green tiles and red bricks on the streets and alleys.

Jiang Yubai held up an umbrella and walked into the school gate of Provincial No. 1 Middle School.

The driver shouted behind him: "Mr. Xiao Jiang, your water cup has fallen on the car!"

"It's okay, I'm not thirsty. I will hand in the paper in advance," Jiang Yubai replied in a faint tone, "Mathematics is the subject I'm best at."

It's time to prove yourself!

Jiang Jubai is full of confidence.

The heavy snow was rising all over the sky, like willow catkins, gradually like feathers. Jiang Jubai held an umbrella, walked forward alone against the wind and snow.

The light snowflakes fell on his ears, and he heard a familiar voice: "Jiang Yubai! Jiang Yubai! Wait for me!"

Jiang Yubai stopped, but did not turn around.

Lin Zhixia rushed towards him: "Jiang Yubai, how are you studying? Are you sure?"

Jiang Yubai raised the edge of the umbrella slightly, then leaned to the side, covering Lin Zhixia's head. He inadvertently revealed: "I have a mathematician tutoring team. They gave me some lessons and made up for a week."

"That's great!" Lin Zhixia said with great confidence, "You will definitely be able to write a complete test paper!"

Jiang Jubai's confidence was high and he couldn't help but hold the handle of the umbrella tightly.

It was cold today and the winter wind was bleak. Fortunately, there was a cabinet-style air conditioner in the examination room.

The two air conditioners operated together, maintaining a constant indoor temperature of 23 degrees. The warm wind blew the students present, their expressions were either solemn or nervous, and a few people were too nervous and could only adjust their breathing continuously.

But Lin Zhixia didn't feel any anxiety.

She was never afraid of passing the exam.

The so-called "exam" is more like an interesting game to her.

She sat down calmly and waited for the invigilator to distribute the test papers.

Compared with Lin Zhixia's casual attitude, Jiang Yubai can be called "waiting hard". He arranged the ruler, pen, eraser, compass and other stationery supplies in sequence, neatly arranged.

When he got the test paper, he immediately reviewed the questions.

The questions on this paper are very profound and require a broad knowledge area, huge amount of calculations, and exquisite problem-solving skills.

Jiang Yubai dared not neglect. He thought carefully and drafted carefully.

After seven minutes of careful consideration, Jiang Yubai solved the three multiple-choice questions on the test paper.

At the same time, Lin Zhixia also completed the entire test paper, including additional questions. In order to kill time, she provided two solutions to each major question.

When ordinary students answer questions, they usually write the word "solve".

When Lin Zhixia answered the questions, she first wrote "Method 1 and Solution" and then "Method 2 and Solution". In fact, she could also write "Method 3", but she was a little lazy.

She closed the pen cover and glanced around.

Except for her, most of the students were racing against time and doing questions wildly. They wrote quickly and looked focused.

There are also a small number of students biting their pen caps with bitter faces. Life is worse than death, and they endure the cruel torture of mathematical problems. To them, the entire examination room is not like the world, it is like eighteen-layer purgatory - the test paper is torture, stationery is shackles, and the admission ticket is shackles that cannot be escaped.

Lin Zhixia watched their expressions curiously.

The invigilator gently knocked on her desk: "Class, please don't look around."

Lin Zhixia nodded and greeted her. Then, she stretched and lay on the table to sleep.

The step classroom of Provincial No. 1 Middle School is designed very well. Each seat has a cushion, and the cushion is filled with sponges. It feels soft when you sit on it, and the table is also spacious. Lin Zhixia relaxed physically and mentally, and fell asleep like this.

There was only a "rustling" sound in the classroom with the tip of the pen rubbing against the paper.

The precious time is passing by minute by second.

Jiang Yubai just wrote on the fourth page of the test paper and gave him a warning to the additional questions.

This additional question describes "uncosided dot sets and binary subset line segments", requiring students to find the smallest positive integer n based on known point set conditions, so that "there are n elements in the set composed of line segments, the binary subset line segments have common intersection points, and the intersection of the subset is an empty set".

Jiang Yubai calmly reread the question stem, and a drop of cold sweat oozed out of his forehead. It was too difficult. He had no idea and could not even understand the question.

Since last week, Jiang Yubai has four math tutors and a math teaching and research team. The teachers tailored a set of learning methods for him and summarized hundreds of questions for him.

However, he still fell into the trap of additional questions.

Jiang Yubai turned his head and looked at Lin Zhixia - the scene in front of him shocked his soul. Lin Zhixia lay on the table and slept quietly. Her eyelashes trembled slightly, her cheeks were pink, and she slept so well.

Has she finished writing?

She must have finished writing.

This is her strength.

The exam is thirty minutes to end. Jiang Yubai gave up the additional questions. Even if he had given him more time, he had no idea to solve the problem.

He raised his hand high and claimed to "submit the paper in advance". So the invigilator took away his paper.

Jiang Yubai stood up calmly, pretending that he had no power to hold an iron pencil case. The heavy iron pencil case fell to the ground with a "bang". As he wished, he woke Lin Zhixia up.

Lin Zhixia opened her eyes and saw Jiang Yubai.

She followed closely behind and handed over the paper immediately.

The invigilator walked towards her and saw that her test paper was covered with traces of answering questions. However, Lin Zhixia had been sleeping almost all the time. Why could she finish writing? Even the additional questions could come up with two solutions?

There were more than 200 candidates in the first ladder classroom.

These more than 200 students come from several of the best primary schools in the city, including many seniors and seniors in the sixth grade of Experimental Primary School.

The seniors and sisters didn't dare to hand in the paper in advance, but Jiang Yubai and Lin Zhixia both walked towards the classroom door.

Jiang Yubai asked Lin Zhixia: "Do you think the test paper is difficult?"

Lin Zhixia answered honestly: "It's so simple!"

OK, simple, simple, ah.

The four words were like a terrifying magic sound, disrupting the quiet atmosphere in the exam room.

The invigilator has rich teaching experience. He quickly stood on the podium and shouted loudly: "Keep quiet, classmates, don't whisper! Pay attention to the discipline of the exam room! There are still thirty minutes left before the exam will end!"

Lin Zhixia stood outside the examination room and could still hear the roar of the invigilator.

She grabbed her schoolbag and followed Jiang Yubai to the outside of school.

"Jiang Yubai, how did you do in the exam?" she asked without hesitation.

Jiang Yubai hesitated for a few seconds before saying, "I can't write the last additional question." After that, he held an umbrella with his left hand and put it in his right hand in his clothes pocket, and his eyes extended further to the horizon.

As he expected, Lin Zhixia was surprised. She murmured to herself: "Is the additional question difficult? Is it really difficult?"

She was deeply trapped in a confused swamp, unable to tell what is simple and what is difficult. She also helped him sort out his ideas: "You can build a connectivity diagram and substitute the connectivity branch and arrangement formula..."

"I haven't learned the Connection Picture." Jiang Yubai told her.

"What about other students? They are even more likely to have learned it!" Lin Zhixia found an entry point, "The exam is about ranking, not total score. Even if you only get twenty points, as long as you get into the top seventy, the 2005 competition class will definitely accept you."

Jiang Yubai never passed the 20s.

In fact, if the full score of the test paper is 100, Jiang Yubai has never scored below 97.

Jiang Yubai looked at Lin Zhixia with a complicated expression.

Lin Zhixia thought Jiang Yubai was worried about his achievements.

Before hesitation, Lin Zhixia made a quick decision and pulled Jiang Yubai back to the stairs classroom. They waited for more than ten minutes, and when all the students in the examination room handed in the papers one after another, Lin Zhixia caught several people on the spot and interviewed: "Hello classmate, how do you think the overall difficulty of this math test paper is?"

The classmate who was interviewed was about twelve years old. He wore a pair of black-framed glasses, looked haggard, his scattered hair was on his forehead, and his mind was also a little dazed: "Haha..." He let out a desolate and sad laugh: "Haha...math test paper...so simple!"

"Simple?" Jiang Yubai asked in surprise.

At first, Jiang Yubai thought that he could get into the competition class even with his eyes closed. After listening to the description of the unknown classmate, Jiang Yubai became suspicious of himself.

Lin Zhixia comforted him: "Don't be afraid, you are amazing! Jiang Yubai!"

Then, Lin Zhixia found another girl and asked persistently: "Hello, this classmate, I'm disturbing me. Do you think this math exam..."

Before Lin Zhixia finished speaking, the girl threw off her schoolbag and whimpered loudly. The girl and her elementary school classmates came to take the exam. Neither of the two girls did well, and they actually hugged their heads in the corridor and cried.

There was a breath of sadness, sorrow, and depression.

Lin Zhixia was shocked by them. This was her first time getting close to a group of ordinary students who failed the exam.

She calculated the admission probability, and 287 people took the exam, and finally only admitted 70 students, with an admission rate of only 0.2439. She randomly interviewed candidates, which was equivalent to random sampling. The sample did not include Jiang Yubai and Lin Zhixia. Then, the probability of her drawing two students destined to be eliminated was as high as 0.58.

She interrupted the interview and walked towards the stairs.

A young man's voice came from behind: "Are you the one who has been sleeping for more than an hour, handing in the paper in advance, and saying that the paper is simple?"

Lin Zhixia turned her head and saw a boy about twelve years old. The boy had a buzz cut, handsome facial features, a high nose bridge, and a long black jacket with dark blue pen ink on his right index finger and thumb.

He took the lead step by step: "I am the winner of the first prize of the provincial 2004 Hualuogen Primary School Mathematics Competition. I went to Beijing to participate in the competition. Where are you?"

Someone around him grabbed him and called him: "Duan Qiyan, the first god of war, don't fight with girls."

There was also a classmate next to him who echoed: "Duan Qiyan is in the Affiliated Primary School of Normal University, and he takes the first place in the school every year. His nickname in the school is 'No. 1 God of War', which we all know."

Duan Qiyan pulled his arm back and glanced at Lin Zhixia: "You and that boy handed in half an hour in advance, which disrupted many people's plans. You slept in the examination room for at least an hour. You two are obviously both sluts. Just squat at home, don't come to the examination room of the competition class to make trouble."
