I sorted through the papers and topics on the table again.

Lin Yi spent another few hours simply trying to solve a problem, then broke down the numerical model into a paper, and wrote it down in a clear and logical manner.

As soon as I wrote this and found the feeling, it took me a whole night.

"Numerical modeling is indeed much more useful than pure mathematics. It's no wonder that so many guys from the mathematics department have various career development paths."

Lin Yi stretched his waist.

In the past, when others told Lin Yi that learning mathematics could be of great use, Lin Yi would never believe it.

Not to mention Baeknam County or Myeonghae, even in Gangseong, the capital of Haeju Province, or Gyeongnam, when you find a random student and ask him what the use of mathematics is.

Ninety-nine percent of people will say that learning mathematics is just to get high scores in exams, go to a good university, or to make it easier to keep accounts in the future.

As for going to college and graduating from the mathematics department?

What ordinary people can think of, apart from being a math teacher, is to continue their studies after graduation. Otherwise, they will be unemployed after graduation, and it is difficult to think of other fields.

But now that Lin Yi has come into contact with digital analogues, he feels a sudden sense of enlightenment.

Use mathematical models to solve real-world problems.

This feeling was like when he was practicing and used spiritual energy to gather magic for the first time.

A bit novel.

After Lin Yi finished writing, he read it again from the beginning and sorted out the structure and context of various knowledge points.

At a glance, it was already six o'clock in the morning.

Zheng Qiuchan knocked on the door, three times in a row, and the sound was relatively heavy, as if to remind the people in the room.

"Are you up? If so, let's have breakfast together?"

She was still hesitating whether to give Lin Yi some more time.

On the night when Gong Yi said she stayed at a friend's house, Zheng Qiuchan had doubted whether Lin Yi had stayed with him all night, but she couldn't find any clues afterwards.

But last night, she saw Gong Yi and Lin Yi standing together at the door of the room.

If she told Gong Yu about this, Zheng Qiuchan wasn't sure how she would feel based on Gong Yu's character.

Although Gong Yu expressed his admiration for Lin Yi both inside and outside his words, it remains to be seen how much of it is true and how much is false.

If only he knew that Lin Yi had refused to become his brother-in-law before, and then turned his sister into a cooked rice...

Zheng Qiuchan felt that she really didn't know how to explain to this old classmate.

Zheng Qiuchan had a lot of chaotic thoughts in her mind.

Before she could take back her hand, the door to the room opened.

One opens two.

Lin Yi was standing in front of him, and Gong Yi was walking out of the door of a room apart.

"well?"

Zheng Qiuchan was startled, looking at Lin Yi and then at Gong Yi over there.

"Good morning, Sister Qiuchan."

Gong Yi didn't sleep well all night and was still worried about what would happen tonight.

It was really a helpless move to come to Lin Yi. She really didn't know who to look for to solve this matter.

After all, they are still students, unless they are looking for Gong Yu, but after looking for Gong Yu, Gong Yi was safely locked back home. As for Huang Jiaoer and the others, it is hard to say how much effort Gong Yu is willing to put in.

.

"morning."

Zheng Qiuchan felt that there was some misunderstanding here, but she couldn't tell where the misunderstanding came from: "Now that we're up, let's have breakfast together."

Gong Yi did not refuse, turned around, washed her face, and put on light makeup.

Makeup is a girl’s second face.

Until she went out, the three of them went to the breakfast buffet on the second floor of the hotel.

At the dinner table, Gong Yi and Zheng Qiuchan sat opposite Lin Yi.

Lin Yi was eating the steamed buns in his hand and drinking hot porridge, while Gong Yi frowned and looked somewhat haggard.

Zheng Qiuchan's eyes wandered back and forth between the two of them, somewhat confused about the situation.

"You guys came back together last night?"

Zheng Qiuchan asked.

"No, I was waiting for him in the hall."

Gong Yi shook her head.

Wait for him?

Zheng Qiuchan looked at Lin Yi again: "Then you... saw Chen Linyan yesterday?"

"What did you say?"

When asked this question, Gong Yi subconsciously looked towards Lin Yi.

Chen Linyan.

The name made her pay more attention.

Judging from the name, she must be a pretty good-looking girl.

"We talked about the recent situation, but didn't say much."

Lin Yi finished eating and wiped the corners of his mouth with a napkin: "Aunt Lu and my mother asked me to go there because they were afraid that something would happen to her when she was studying abroad alone."

Zheng Qiuchan nodded and said no more.

Gong Yi remained silent.

Zheng Qiuchan didn't ask why Gong Yi was waiting for Lin Yi. She might not get the answer she wanted if she asked, but what Zheng Qiuchan was thinking about was whether to tell Gong Yu.

"Teacher Liu's flight should arrive in Yanjing around ten o'clock in the morning. It was supposed to be a few days later, but Teacher Gu wanted to catch up with Teacher Liu and take him for a walk, so he asked him to change the ticket.

.”

Speaking of this, Zheng Qiuchan paused and moved the finished plate aside: "Will you come with us later?"

"According to your teacher's wishes, he doesn't want you to know that he is here so early, for fear that you will be under psychological pressure."

"Let's go together."

Lin Yi shook his head. He hadn't seen Lao Liutou for a long time and wanted to meet him after all.

He looked at Gong Yi who was in a daze after eating half the meal.

"After you finish eating, you can rest here, or you can go home. I'll find you when I'm free."

"Um."

After breakfast, Gong Yi stayed at the hotel.

Zheng Qiuchan and Lin Yi went out together and went to Huaqing University.

At the school gate, Zheng Qiuchan called Gu Chujie and waited there.

"What's the relationship between you and Gong Yi?"

Zheng Qiuchan finally found the opportunity to ask, and looked at Lin Yi: "If you really like it, or have done something, and you are asked to take responsibility when the time comes, if you want to run away, as her brother's old classmate, I'm afraid I will have to

Consider tying you up and sending you to their home."

"It doesn't matter that Gong Yu got in the car that day because he wanted to give you his sister cheaply, but if you really want it and are irresponsible, just because Gong Yu is a girl-controlling guy, I really have a reason

I wonder if he will pursue you to the end of the world."

Sister control.

Listening to these two words, it was really difficult for Lin Yi to associate the guy who would rather pay Gong Yi with the dowry to these two words.

"I have no relationship or contact with her."

Lin Yi sighed and looked at Zheng Qiuchan seriously: "Am I that hungry?"

"Or, Teacher Zheng, do you think I'm the kind of person who falls in love with everyone I meet?"

Seeing Lin Yi asking such a serious question, Zheng Qiuchan breathed a sigh of relief and at the same time looked at Lin Yi with a serious face that was ready for battle.

She hesitated for a long time, hesitated for a long time, and thought for a long time.

After thinking about it in my head, I really didn't think of any girl that Lin Yi was too enthusiastic about.
