Duan Yun finished the club competition in the afternoon, and after dinner, he came to the library and began to do some Olympiad training problems with Yang Ying and Liu Linna.

Now the quota for the Olympiad group has been determined, but these two girls are still working hard, and there is a thick pile of various test papers next to the table, and the training intensity seems to be better than before.

In fact, there is no need for Duan Yun to participate in this kind of Olympiad training, but considering that in addition to the individual rankings, there is also a team competition in this national Olympiad competition, and the previous principal Qin Dong also promised a high prize money for the team competition, for this money, Duan Yun needs to help Yang Ying and Liu Linna.

And Duan Yun and these two girls have a good personal relationship, so Duan Yun should also pay in terms of friendship.

The library tonight was exceptionally quiet, except for Duan Yun and the two girls, there were hardly any other students in sight.

When Duan Yun sat opposite the two, Yang Ying and Liu Linna's eyes suddenly focused on him.

"Isn't Ouyang Xiangnan with you?" Yang Ying suddenly asked at this time.

In fact, the last time they had dinner, these two girls already knew about the relationship between Duan Yun and Ouyang Xiangnan.

And because Duan Yun and Ouyang Xiangnan have been inseparable in the past two days, tonight is also the first time to see the evening Olympiad training after the last exam at the principal's place.

"She had something at home and asked for leave to go home. Duan Yun replied casually.

"Well, that's right. Yang Ying's eyes lit up when she heard this, and she said: "I used to think that you were very good at Olympiad mathematics, but I really didn't expect that it would be so strong. ”

"Yes, Duan Yun, you are indeed a mathematical genius. Liu Linna on the side also smiled slightly, and then took out a few exam questions that had already been prepared, handed them to Duan Yun and said, "This is the test paper from the last time I took the exam with the principal, and I can't answer the last question anyway, can you help me explain it." ”

"Absolutely. Duan Yun took the exam paper with a smile, but he didn't rush to answer, but put the exam paper aside first, and said, "Actually, after the last exam, the principal once talked to me about our National Mathematics Olympiad. ”

"What did the principal say?" Yang Ying and Liu Linna asked curiously.

That's the ......"

Duan Yun talked to the two of them about the rewards of this National Mathematics Olympiad that the previous principal Qin Dong talked to him about.

"A million bonus!?" Yang Ying was taken aback when she heard this.

"That's right, whether it's the champion of the team competition or the individual competition, the school will award a million in cash. Duan Yun nodded.

"If I can win the team competition, I don't need any prize money. At this time, Liu Linna raised her eyebrows, and then said: "But I hope that Duan Yun can give us more ...... pointers."

Obviously, Liu Linna doesn't care about money, all she really needs is the qualification to apply to a key university.

Of course, for Duan Yun, money is also very important, if not, he only needs to win the individual championship, and there is not so much motivation to 'guide' Yang Ying and Liu Linna.

"Duan Yun, as long as you can tutor the two of us well, if you win the award, my share of the bonus can also be ......" Yang Ying also interjected at this time.

"Okay, okay, what do you think of me as someone, am I so greedy for money?" Duan Yun pouted and said.

"Yes!"

Yang Ying and Liu Linna said almost in unison, but then they giggled.

"Actually, we are all a team now, and I will definitely have no reservations. Duan Yun patted his chest and reassured.

Then thank you, and if you have time, I will invite you to dinner. Liu Linna said to Duan Yun with a smile.

"You both sit down. Duan Yun snapped his fingers and said, "From today onwards, I will give special training to the two of you." ”

When Yang Ying heard this, she directly sat on Duan Yun's left with a smile, while Liu Linna hesitated for a moment, and finally sat on Duan Yun's right.

Feeling the faint body fragrance on the two girls, Duan Yun suddenly perked up, and after spreading out the exam paper just now, he officially started today's intensive training.

……

At the same time, in the VIP room on the top floor of the Tiangui Hotel in the center of Heyang, Ouyang Xiangnan had already changed into a gorgeous evening dress, sat at the dining table with his parents, and talked and laughed softly.

"Xiao Nan, do you think the kid surnamed Duan is reliable, if you are not satisfied, I will help you change the companion. At this time, Ouyang Cheng, who was sitting in the middle position, took a puff of cigarette and said to his daughter with a slight frown.

"It's okay, although he is a little greedy for money, but his cooking skills are not bad, and he is also very obedient. Ouyang Xiangnan said with a deep groan.

"That's good. Ouyang Cheng nodded when he heard this, and said, "If that kid makes you angry, call me, and I'll clean him up." ”

"There's no need. Ouyang Xiangnan shook his head and said, "By the way, Dad, I heard that Duan Yun say that when he used to go to school in the locomotive factory middle school, he was not in good health and often fainted, is there such a thing?"

"That's right, I've had people touch the bottom of this kid before, he used to be nicknamed 'Glass Man' in locomotive factory middle school, his body can't do strenuous activities, and he often faints inexplicably......"

"Then this seems to be a little the same as our Xiao Nan's symptoms. Ren Tingting, who was on the side, said in surprise when she heard this.

"It sounds the same, but there's nothing wrong with that kid's heart. Ouyang Cheng shook his head, and then said: "And later, this kid's illness suddenly improved, and he became the captain of the school's football team, and his body seemed to recover overnight...... In fact, the reason why I paid a high price for this kid to be a companion to our Xiao Nan is because he had the same symptoms as Xiao Nan before, maybe this kid can really help Xiao Nan recover his health......

When Ouyang Xiangnan heard this, a different color flashed in his eyes, and he seemed to be thoughtful.

"Knock knock!"

There was a knock on the door outside the private room.

"Come in!" Seeing this, Ouyang Cheng shouted.

"Uncle and aunt...... Xiao Nan, hello. ”

The moment the door opened, a tall man walked in.

I saw that this man was wearing a brand-name suit, tall and straight, with slightly curly hair, fair skin, delicate and handsome facial features, carrying a gift bag in his hand, and the platinum watch on his wrist shining in the light.

"Sit!" Seeing this young man appear, a smile suddenly appeared on Ouyang Cheng's face.

"Originally, my father was going to come with me to visit my uncle and aunt, but he has a very important business to discuss tonight, and he will not be able to fly to Heyang tomorrow morning, so please forgive my uncle and aunt. After the young man explained politely, he immediately sat down next to Ouyang Xiangnan, put the gift bag in his hand on the table, and said with a smile: "I bought these things before returning to China, I hope you like them." ”
