Money matter is quite annoying to Li Xuan, because after experiencing a life without money, he knows that money is too important.

In fact, scientific research also requires a lot of money.

Many foreign scientific researchers are rich second-generations, or at least they have no worries about food and clothing. Who has no money and has the energy to study science.

Can feelings be eaten as food?

Speaking of scientific research funds, it has always been a big problem for scientific researchers, because not everyone can prove the international mathematical conjecture and get enough scientific research funds. Too many scientific researchers in the world live a poor life and want to earn some extra money, they will be criticized by keyboard warriors, saying that they have defiled science.

Doing scientific research for the country, it is better to have half the salary in a large enterprise than to have a seniority. The reality is that the salary of a doctoral supervisor who is almost 40 years old may not be as high as that of undergraduates who have graduated for five years, which naturally leads to the loss of talents. Many people with high IQs are unwilling to go to scientific research.

Scientific research results are all made with money, especially in cutting-edge fields. With such a harsh environment, Chinese scientific researchers can still produce so many results, and it is already amazing to upgrade some technologies to the top in the world.

Li Xuan admires national scientific researchers very much. He thinks that those who do scientific research are all because they really love science and love this country. Otherwise, if they have no money like this, who is willing to sacrifice themselves?

So, Li Xuan thought that one day he would do research and would not worry about money?

If you don’t have a system, you will definitely know it. If you have a system, it’s hard to say. This is also the reason why Li Xuan has confidence.

There are also elegant ways to make money when making money, such as writing books, domestic popular science books, and textbooks that are poor, and there has always been a lack of good textbooks.

But the problem arises again.

Li Xuan checked the book market and found that writing books is not profitable, especially books about popular science teaching. He felt quite melancholy, no wonder no one was willing to write them. Top universities in China value scientific research more and do not attach much importance to education.

...

Then the new year is coming soon, and there is another Christmas before New Year's Day. This kind of festival is unsatisfactory, but the meaning of Christmas spirit's broken shell day is extraordinary.

When Christmas comes, you naturally have to buy gifts, so what gifts to buy is a question worth thinking about.

Love is one of the most troublesome problems.

Because Xu Lingchu's family is well off, buying necklaces and earrings is not very cheap. Of course, the main reason is that Li Xuan can't afford expensive ones.

Li Xuan really doesn’t understand what girls like, but fortunately he upholds a simple concept of love, raising a girlfriend is the same as raising pigs.

Simply put, buy food.

Because class is going to be held on Christmas Day, I can’t hold a birthday party, so I can only make an appointment to meet on the rooftop in the evening.

Li Xuan spent the whole day watching mathematics, and only started to take action after the evening self-study.

The rooftop is indeed a good place. Li Xuan thinks that it is best to have a rooftop in the school’s teaching building. There are also diligent students to clean every week to keep the rooftop clean.

Originally, there were no people on the rooftop after evening self-study, but today is Christmas, and there are still many people who are unexpectedly expected.

Li Xuan had to change the place and take Xu Lingchu to the corner of the lake to give her the carefully prepared gifts.

Xu Lingchu opened the gift and found it was chocolate. She stared at Li Xuan, and said with her cheeks, "Why buy so much food for me? You won't think I'm a pig, right?"

Li Xuan smiled: "How could it be? I just think you won't get fat no matter how much you eat!"

"Really?"

"real!"

Xu Lingchu frowned slightly: "But I have gained five pounds these days, so it's really not OK to go on again."

"Girls are more fat than they are cute!" Li Xuan said seriously.

Xu Lingchu was silent, stared at Li Xuan, and said seriously: "Do you still remember, what gift did you buy me last time you went to the capital?"

As soon as Li Xuan said that he remembered that he bought pastries at the food street when he went to Peking University for training. "I remember it seemed like I was eating it."

"You remember..." Xu Lingchu nodded, "Then the midterm exam, the review notes you gave me were circulated throughout the year, causing my ranking to regress. How did you comfort me?"

"Have you bought a delicious cookie bear cake?"

"And then, last Sunday, you ignored me all day and made me unhappy. How did you coax me on Monday?"

“Extremely fragrant beef jerky.”

"To be honest, did you really not raise me as a pig? I was almost crying! I didn't lie to you!" Xu Lingchu looked at Li Xuan, bit his lip with aggrievedness, and couldn't help but stomp his feet gently.

Li Xuan: “…”

Xu Lingchu said: "I am quite happy when you give me a gift. I think it was you who gave it, so I must eat it clean. And the food you gave is also very delicious, so delicious. Then after I was happy, I felt a little unhappy. I had a very small appetite and really couldn't eat it..."

"Okay." Li Xuan also realized that his girlfriend is indeed a little different from a pig and could not be raised as a pig. "Then what gift do you like? Tell me? I'll buy it for you again."

"I don't care. Anyway, you have to think about it yourself, it can't be eaten." Xu Lingchu looked at Li Xuan frowned, couldn't help but smile, stood on tiptoe, leaned against his ear, and murmured softly, "Didn't you want to see me wearing a miniskirt last time? If you make me happy, I'll wear it for you."

Li Xuan looked at him in a daze, his eyes a little different.

Then he laughed: "To be honest, today is your birthday, and it is also Christmas Day. It was just a Christmas gift just now, and I haven't given you a birthday gift yet."

Xu Lingchu was slightly stunned, pursed her lips, and smiled again in her eyes.

Li Xuan picked up the plastic bag-packed test paper from his schoolbag, "This set is the test paper I have treasured for a long time. It is very classic and the answers are detailed. Please keep it refreshing after writing it! I can't bear to do it myself! I have the same questions and take it. On such a good birthday, how can I be happy without making a test paper?"

Xu Lingchu: “…”

It’s such a good birthday, why don’t you be happy if you don’t do a test paper?

Well, I don’t want to do the test papers I have collected for a long time, and I share the questions. Is it so terrible... In the world of academic masters, she doesn’t understand the reason very much, no, it’s really difficult to understand.

She was completely confused. She should have performed happily at this time, but she couldn't laugh. When she went back to Christmas Eve, who would still want to do the test?

Seeing Xu Lingchu's shocked look, Li Xuan's expression on his face was not tense and he couldn't help laughing.

"Hahaha!" Li Xuan was about to die of euthanasia.

At first, Xu Lingchu didn't react. When she saw Li Xuan's smile, she realized it and her face turned slightly red.

"Damn it, you teas me again!" She was very angry, but when she saw Li Xuan's smile, she couldn't help laughing and grabbed Li Xuan's clothes, "Damn it, you are not allowed to laugh, don't laugh! You are still laughing!... What's so funny, it's very boring..."

Li Xuan stopped laughing and took out another book from his schoolbag, "Okay, this is a birthday gift."

"It's a book again." Xu Lingchu took a look with disgust, and there was a psychological shadow.

"It's different, you can see it yourself."

Xu Lingchu was unhappy, so she opened the book and saw the entire contents of the book through the dim street lights.

I thought it was an exercise, but she found that it was not at all. This book was very unusual. Because she could record life in Penguin Space, only private Li Xuan could see some of the contents. Li Xuan printed all the logs, photos and talk about her space, carefully bound them into books, and gave them to her.

These logs and stories also have her dark history, but these are no longer important at this moment. Her eyes were slightly red and she fell into a huge touch.

"I will only be included in the last few pages of this book, and I will be included in your books in the future."

Finally, Li Xuan smiled and said.
Chapter completed!
