Bai Yueguang came back with the system

The hotel they stayed in was near the south gate of the High School Affiliated to Qiong University. When they walked to the school gate, volunteers at the school gate saw them carrying blue and white conference certificates and guided them to the lecture hall with a smile.

When Yu Yanchu and the others arrived, the opening ceremony was about to begin. The group of people they met yesterday were sitting conspicuously in the front row of the lecture hall.

They casually found a seat at the back and sat down, where souvenirs, mineral water and brochures on conference arrangements were placed.

There were whispers from other participating students——

"See, those twins are sitting in front."

"Their mothers are really good at giving birth. They gave birth to children with two IQ ceilings."

"I just want to be like them. My family is rich and my IQ is high. Hey, it would be great if I can win a gold medal this time. I don't expect to make it to the national team."

"Who isn't?"

The chairman of the Chinese Mathematical Society, an academician of the Chinese Academy of Sciences, the mayor of Qiong City, the director of education and other big figures attended the opening ceremony, which shows that they attach great importance to the finals of this mathematics competition.

The principal of the High School Affiliated to Qiong University delivered a speech first, expressing a warm welcome to the teachers and students who came to this event. Then announced the itinerary and finals system of the winter camp: the itinerary lasts for six days in total, with the opening ceremony on the first day, exams on the second and third days, academic reports and tours on the fourth and fifth days, and the closing ceremony on the sixth day. Exam results and awards. The CMO exam is completely simulated by IMO. Gold medals account for 1/3 of the total number, about 200 people. The top 60 people enter the national training team and compete for the last 6 places to participate in international competitions.

After the academician gave an encouraging speech to the students.

Yu Yanchu opened the booklet, and it was the turn of the participating student representatives to speak.

A tall boy sitting in the front row stood up. He was one of the twins he met yesterday.

Yu Yanchu couldn't tell whether he was an older brother or a younger brother. From a distance, he could only see him standing still in front of the microphone, adjusting the height of the microphone, and began to speak.

Compared with the students around who were slightly excited to see the handsome guy and a math peer, Yu Yanchu felt sleepy after hearing this.

"I believe that in the not too distant future, there will be leaders in the field of mathematics among all of you, who will contribute to the development of the country's basic disciplines and the progress of human civilization."

There was a round of applause in the conference hall.

Next was a school play about mathematicians prepared for the guests by the High School Affiliated to Qiong University, as well as art performances.

The High School Affiliated to Qiong University is indeed the best high school in Qiong City and even in the country. The student actors in the campus drama are all handsome men and beauties, and their performances are believable. The quality of the ensemble is also very high.

After the opening ceremony, volunteers led participating leaders and guests to visit the campus.

After the big guys left during the visit, the atmosphere became more relaxed. After all, the volunteers and participating students were all young high school students.

It was Tang Yufu, the heroine of the campus drama, who led a dozen students from Yulin to visit. She had big eyes, a high nose, and bright lines. The smile on her face became more sincere after seeing Ji Heng.

"Long time no see, Ji Heng."

Ji Heng nodded expressionlessly, while Tang Yufu smiled and was not angry.

"Welcome to the High School Affiliated to Qiong University. Let me take you to visit the school history museum first."

As soon as they finished speaking, two uninvited guests entered their team.

It was the twins who had just spoken.

The two of them stood beside Tang Yufu, one on the left and one on the right, speaking in unison lazily.

“Welcome to the High School Affiliated to Qiongda University!”

"Xiao Fu, please take us to review the history of our beautiful school."

Tang Yufu's smile remained unchanged, "Of course."

They were a group of tall, handsome men and beautiful women. The leader was the school belle and school boss of the High School Affiliated to Qiong University. She was very eye-catching walking on the red brick and gray tile campus.

During the process, several girls from the high school affiliated with the school were seduced by Lin Mingjia's beauty and boldly stepped forward to ask for Lin Mingjia's WeChat account. Before Lin Mingjia could refuse, the twins drove him away with threats.

Yu Yanchu slowly wanted to move to the end of the team to be with the first and second grade students from Yulin High School, but he was spotted by his sharp-eyed twin brother Sheng Xiangyang on the way.

He moved to Yu Yanchu's side with his brother who didn't know what he was doing, and said to Lin Mingjia who was guarding her, "Lin Mingjia, why don't you introduce this classmate?"

Ji Heng was being chatted with by Tang Yufu attentively, with a look of indifference.

Hearing this, he immediately raised his eyes, "Hey! I'm warning you -"

Ji Heng, who has been dealing with them for several years, knows very well the virtues of these twins, especially their elder brother Sheng Xiangyang, who is a carefree person.

Before Ji Heng finished speaking, Sheng Xiangyang understood what he meant. He spread his hands and said helplessly, "If you don't say it, don't say it. I will always have a chance to get to know her."

After visiting the school, all participating students took a group photo at the track and field field, and the first day of the trip was finally over.

Back at the hotel, Yu Yanchu took out his thin notes and read them carefully from beginning to end to prepare for tomorrow's exam.

The exams on the second and third days went smoothly.

The two-day exam is completely simulated by the International Mathematics Olympiad (IMO), with 3 questions per day and a time limit of four and a half hours to complete. Each question is worth 21 points, with a maximum score of 126 points.

Yu Yanchu and the other people in Yulin were shuffled and placed in different examination rooms.

After the exam, Mrs. Qiu took a few students to summarize the exam content.

After the other four people finished recalling, Master Qiu looked at Yu Yanchu, "Yanchu, do you have anything to add?"

"That's basically it." Yu Yanchu thought for a moment, "I'll add two more points, the Menelaus theorem of plane geometry, and the recursive sequence and its properties in the algebraic part. The title is -"

The girl's cold voice sounded in the hotel study room, and Shi Shuang stared at Yu Yanchu with envy.

Master Qiu nodded with satisfaction and recorded it.

"Okay, the battle is over. You can have fun in Qiong City for the rest of the time." Then she pushed up her glasses and added, "Remember to issue invoices for meals and taxis, and the school will reimburse you."

When leaving Master Qiu's guest room, Yu Yanchu's cell phone rang. She took it out, took a look, and turned off the screen.

Ji Heng happened to see the screen from the side, "Sheng Xiangyang?"

Yu Yanchu said "Huh" and immediately stepped into the elevator without wanting to explain more.

Ji Heng was behind her, looking at the girl's slender and tall back, and complained to Lin Mingjia next to her.

"When did Sheng Xiangyang add WeChat?"

"Why did he add it after all precautions?"

Lin Mingjia looked at Ji Heng dumbfounded, "He is the student leader of this competition and the president of the student union of the High School Affiliated to Qiong University. It is not normal to add WeChat."

Ji Hengjun's face fell slightly and he sighed, "No, you don't understand."

Lin Mingjia couldn't explain it. Well, maybe he really didn't understand.
