"Is your phone out of battery again?"

Zheng Qiuchan saw Lin Yi walking towards this side with a look of helplessness on her face. As she spoke, she felt an indescribable headache.

"It seems the power is out."

Lin Yi took out his cell phone and took a look.

It has automatically shut down.

Unlike those who kill time with their mobile phones all day long, Lin Yi rarely plays with his mobile phone.

It's just that the standby time of Apple's mobile phone is really too short, and it will automatically shut down from time to time.

"Prepare a backup phone in the future, otherwise, I won't be able to find your person every time, and I won't be able to get through when I call you."

When Zheng Qiuchan was talking, Wang Hao next to him went upstairs first.

There was no need for him to come to school again.

Wang Hao chose to go to school before just to escape various troubles in his family.

Nowadays, he is no longer what he used to be, and his strength and identity have completely changed.

The reason why I chose to come here to continue taking classes was probably similar to Lin Yi's, which was just to experience university life.

In a few years, when you get older, whether you have money or power, you will never have the chance to go back to school.

"What's matter?"

Lin Yi looked at Zheng Qiuchan. Logically speaking, he had asked for leave before, and this time he was away for only a few days.

Zheng Qiuchan didn't make any sense. She would have waited anxiously and anxiously under the dormitory building.

"It's a question of your qualifications for the digital modeling competition."

Zheng Qiuchan sighed: "We originally negotiated with Director Chen of the Mathematics Department, and with Teacher Gu's guarantee, your place in the competition can basically be confirmed."

"But something has happened in the past few days. First, in the past three days, Director Chen has organized several doctoral tutors from the Department of Mathematics to explain some mathematical problems to your group of students, but you have been absent one after another."

"Although I told him about it for you, looking at the appearance of Director Chen and other extremely mathematics Ph.D. supervisors, I still have some prejudices against you."

"The second reason is because someone is back, and he may also need a place in this competition."

Zheng Qiuchan briefly talked about what happened in the past few days.

And judging from her appearance, she seemed to be particularly afraid of the person she was talking about.

"This afternoon, Director Chen happened to be explaining some mathematical problems in person. You came back at the right time. If you don't go this time, I'm afraid Director Chen will really be angry."

After Zheng Qiuchan finished speaking, she rushed Lin Yi back to the dormitory and asked him to put down his things, take a shower and change clothes before coming down.

In the past two days, Lin Yi had traveled a lot.

Zheng Qiuchan was a little envious of Lin Yi's state of being able to leave whenever he wanted, free and as he pleased.

When she was in school, although she was Gu Chujie's favorite student and the top student from childhood to adulthood, those were the results she had earned by spending a lot of time and hard work in her studies.

This is completely different from how Lin Yi, who seemed to others to have achieved unparalleled results in a quiet study period.

When Lin Yi returned to the dormitory to take a shower and change clothes, he discovered that there was an extra computer in the dormitory.

Tan Shumo and Zhao Mingming were hacking there, playing games and shouting loudly from time to time.

It was obvious that the two of them were having a great time, but Zhao Mingming, a good young man who always strived for progress and loved reading, was also led astray by Tan Shumo.

Seeing Lin Yi coming back, they asked Lin Yi to come and cut two plates.

Lin Yi went downstairs after changing clothes, and rushed to the conference room of the school's mathematics department with Zheng Qiuchan.

This place has always been occupied by the Department of Mathematics for a long time.

As an integral part of the Department of Mathematics of Jiangzhe University, this conference room has been used several times to welcome well-known scholars in the international mathematics community to conduct academic exchanges and discussions here.

This place, naturally, is also used as a training ground for the top students in the National College Student Digital and Modeling Competition every year.

now.

Director Chen, who looked serious, was talking about a topic about drilling layout, which required the use of mathematical models to design the same mining area and maximize the benefits of ore mining with the minimum number of mines.

"This question is a typical numerical model construction problem. The existence of mathematical models is to solve the problem and find the optimal solution. Now that the conditions have been given, does any of the following people think of the key to solving the problem?

"

Director Chen pointed to several conditions on the projector screen.

There are not many things given, but they mostly involve knowledge points such as sequence and coordinates, so as to design a reasonable digital-analog layout.

"This question is a bit difficult, and the conditions are really lacking."

"If it's just a plane, it's easy to calculate. But now it still involves the depth of drilling. What should we do?"

"Not only that, it also involves the cost of renovation of some old wells. If the old wells are used, the cost will be greatly reduced and the efficiency will be improved."

under.

A group of students from the Department of Mathematics looked at the topic on the curtain and immediately started discussing it.

But more people still have no clue.

"This topic is much more difficult than the mathematical model of maximizing capital investment that I talked about before. It's still too old."

Zhao Shengping on the side was slightly speechless.

Of course he has a way to answer it, but it will take enough time.

Lin Yi left before and did not participate in his digital modeling training course. Zhao Shengping thought he could take this opportunity to let Zheng Qiuchan watch his class, thus showing his authority to Zheng Qiuchan.

However, what disappointed Zhao Shengping was that Zheng Qiuchan did not show much interest in his course. Instead, she left because the questions were too easy in her opinion.

This made Zhao Shengping feel even more unhappy.

"Today, Director Chen is in class in person. If you don't come, why are you participating in a college student digital modeling competition? Your sister has no eyesight and won't give me face, so I won't bother to give you any more face!"

When Zhao Shengping was thinking this in his heart, his eyes unconsciously looked to the seat in front of him.

In that place, there was a boy sitting.

The boy was wearing a black plaid shirt and had a string of beads-like bracelets wrapped around his arms.

This boy's name is Han Yuan. It is said that he passed the entrance examination of Oxford University in his senior year of high school and is now a junior student in the Department of Mathematics at Oxford University.

He came back unexpectedly this time, seemingly intending to discuss with the school his future application for postgraduate studies in the Mathematics Department of Jiangzhe University.

In the past, only foreign students took the exam to go abroad, but it was rare to see students who had already gone abroad take the exam back.

This news made Director Chen very happy, and even excited the president of Jiangzhe University.

After all, he is a top student from Oxford University, and his willingness to apply for the exam is a recognition of the teaching level of Jiangzhe University.
