　　 After they saw Lin Fan, there was a flash of excitement in their beautiful eyes.

　　 Then, Qi Qi took out a bottle of Pulse from the backpack behind him, and handed it to Lin Fan.

　　 Lin Fan said: "Thank you."

　　 opened two bottles of Pulse and took a sip of each.

　　 Xia Bing and Xia Xue saw this, the joy on their faces became even greater, a pair of cute dimples, looming.

　　 At this time, Professor Zhang Yong walked in from outside.

　　 After he saw Lin Fan, he immediately shouted: "Lin Fan, you are finally here!"

　　 Lin Fanyan could not help but touch his nose.

　　 Last Saturday, Zhang Yong kept sending messages to himself, asking him to come for training early.

　　 However, on Saturday, Xinyue Hotel will auction off 100-year-old ginseng.

　　 The century-old ginseng is related to Lin Tao\'s illness.

　　 Of course Lin Fan needs to go.

　　 It was not until Sunday night that Lin Fan returned to Jiangbei.

　　 On Monday, it was the birthday of his girlfriend Qin Yuxuan, so Lin Fan would naturally go to the magic city to celebrate.

　　 Come and go, Lin Fan has not had time to come to the training room until now.

　　 Zhang Yong said helplessly: "Originally, I wanted to use these few days to give you a good training, but the competition is going to be tomorrow. If I train now, it will affect the mental state of the exam tomorrow."

　　 Zhang Yong said here, he sighed lightly, and said: "I\'ll talk about the rules of the competition again. The mathematical modeling contest lasts for 72 hours in total, and it is very difficult and intense!"

　　 "Especially for Lin Fan, calculations, essays and defenses are required, and the task is very heavy!"

　　 "But, you must not panic and nervous, just play steadily..."

　　 When Zhang Yong saw the mathematical modeling of Lin Fan, Xia Bing and Xia Xue for the first time, he was extremely excited and surging.

　　 He immediately felt that Jiangbei University\'s national awards this year, and even the Higher Education Cup is expected!

　　 But now, Zhang Yong doesn\'t have any confidence anymore.

　　 Zhang Yong, as a professor, knows very well that students who are busy with other tasks near the exam will affect their grades.

　　 He just silently said in his heart: I hope Lin Fan and the others can get the provincial prize.

　　...

　　 The next day, the weather was fine, and a splendid sunrise was like a dragon, soaring towards the sky.

　　 Many students from the School of Mathematics and Computer Science of Jiangbei University walked toward the wide lecture halls.

　　Today...or in other words, in the next three days, they will all have a difficult mathematical modeling competition here.

　　 Counselor Sun Yaodong stood in the corridor in the distance, watching this scene silently.

　　 At this time, a middle-aged teacher who was about 30 or 40 years old said: "Mr. Sun, you let so many students sign up for the Mathematical Modeling Contest. It is useless if there is quantity but no quality."

　　Sun Yaodong said: "That\'s not necessarily true, maybe there will be a few provincial awards among them."

　　 The middle-aged teacher smiled and shook his head. Obviously, he didn\'t take this to heart.

　　 inside the lecture hall.

　　 Zheng Jinbao looked at the tables that were all two meters away, sighed, and said, "This is over, I can\'t copy it anymore."

Next to 　　, students from the computer school and mathematics school have a black line on their faces.

　　 Co-authored, you participated in the mathematical modeling contest, are you plagiarizing ideas?

　　 Zheng Jinbao looked at Song Yi, who was sitting not far away, and murmured, “Anyway, it’s okay with someone as a company.”

　　 After finishing talking, Zheng Jinbao opened the happy water from the fat house, took a big sip, and enjoyed it with all his face.

　　 At this time, Song Yi also looked around.

　　 When he saw Zheng Jinbao, he was obviously relieved.

　　 The scum of learning is accompanied, and we are at the bottom together. This bottom... will also be thicker.

　　 Lin Fan sat calmly on the chair, very leisurely.

　　 It looked like it was not here to participate in a mathematical modeling contest, but to drink tea.

　　 "Xia Bing, Xia Xue, don\'t be nervous, it\'s just an exam, relax." Lin Fan said.

　　 Xia Bing and Xia Xue nodded again and again.

　　If they are participating in the competition with others.

　　 Then, they will be like Lin Fan, very relaxed.

　　 However, this time the mathematical modeling contest was teamed up with Lin Fan, which made me nervous.

　　Because, Xia Bing and Xia Xue decided in their hearts that they must take the best technical exams, and they must not hold back Lin Fan.

"Ding!"

　　 At this time, the whole lecture hall rang a crisp bell.

　　 Then, three professors, all over 40, walked in slowly.

　　 Among them, the professor with white temples said: "Except for the whispering among the players, the rest are forbidden to whisper. Violators will be disqualified from the competition!"

　　 "The National Mathematical Modeling Contest, now starts!"

　　 "Look at the title, everyone!"

　　 As the old professor\'s voice fell, three questions appeared on the projector in the amphitheater and on the computers in front of everyone.

　　 "1. Design a house."

　　 "2, design a drainage system."

　　 "3. Design a parking lot."

　　 "Please choose one of the 3 questions to answer."

　　 After seeing these three questions, all the students were dumbfounded.

　　Design a house? Drainage system? parking lot?

　　 Isn\'t all this supposed to be done by the School of Architecture?

　　 This requires drawing drawings, design plans, etc. It does have some complexity. UU reading www.uukanshu.com

　　 But, what does this have to do with the mathematical modeling contest?

　　 Mathematical Modeling Contest, isn’t it a competition about mathematical calculations?

　　 Here, where does mathematics involve?

　　 The students were startled for a while, and then they started talking in a low voice.

　　 "Which topic shall we choose?" the short man in the computer science department asked.

　　 "The parking lot...seems to be a bit simpler?" The middle-sized mathematics student said hesitantly.

　　 Zheng Jinbao vetoed it, saying: "Of course it is the drainage system. How simple is the drainage system? Just draw a few ditches."

　　 The two looked at each other for a while, then hesitated and said, "Then design the drainage system."

　　...

　　 Lin Fan glanced at the three questions at random, and immediately had ideas in his heart.

　　 "Xia Bing, Xia Xue, what question do you want to do?" Lin Fan asked.

　　 Xia Bing and Xia Xue didn\'t move, they just looked at Lin Fan quietly.

　　 Obviously, it looks like you are choosing the topic.

　　 Lin Fan nodded and said, "Okay, then I will choose."

　　 He touched his chin, and said in deep thought: "In many cities, it is easy to accumulate water on heavy rains. Designing drainage systems is troublesome, but it is still useful..."

　　 "Then let\'s choose the second topic, design a drainage system."

　　 Xia Bing and Xia Xue had no reaction at all, and they nodded repeatedly.

　　 At this time, a clear reminder sounded in Lin Fan\'s mind.

【Ding! Trigger the task and win a national certificate in the mathematical modeling contest. Reward 5 silver red envelopes. 】

　　 Lin Fanyan heard the words, the corners of his mouth raised slightly.
