Paris, France, Avenue des Champs-Élysées.

Qin Hai and Tranquility held hands and walked slowly on the boulevard. The summer sun shines through the leaves on the two of them, dappled and dappled like jumping notes, which makes people feel refreshed. The quiet heart is also filled with bright sunshine, I just hope that this road can be endless, so let the two of them go on for a long time.

"Qin Hai, I thought about it for a while, you have never accompanied me to go shopping like this, people talk about friends in and out of pairs, what is the matter with me and you?" Tranquility tilted her head, looked at Qin Hai, pouted slightly, and complained with a smile.

"Really?" Qin Hai thought for a while, and then smiled: "You can't blame me, when I was in the capital, I said to accompany you to go shopping, every time you don't want to go, okay?" ”

"How many times have you been to me every time?" Serenity retorted in a low voice.

"Uh...... It's not because he's busy. Qin Hai consciously took care of his losses, so he could only find a reason for it.

Qin Hai himself didn't know how his relationship with Tranquility had developed to where he was today. In the early days, he just liked Tranquility's beauty and cheerfulness, but in his heart he always felt that Tranquility was still a little girl, and there was a psychological age gap with himself. Before you know it, Tranquility has grown into a big girl, and the relationship between the two of them has developed to the point where everyone thinks they are a natural pair.

Ning Zhongying and Qin Minghua are now the general manager and deputy general manager of Daqin Group respectively, and the office door is door to door, and when they have nothing to do, they will get together to smoke and drink tea and chat about trivial matters. At first, both parties were a little reserved and didn't know how to talk about the children, but later, as the two young people got closer and deeper. The two parents no longer have any scruples, and they have already quietly called each other "in-laws" in private.

According to the thoughts of the parents of both sides, Qin Hai has turned 26 years old, and Ning Ning is also a 24-year-old young woman, so it should be time to talk about marriage. Helplessly, Qin Hai's work is one after another, and it involves major events at the national level at every turn. I really can't spare the energy to think about my own business. And Tranquility is still a graduate student with a master's and doctorate, and it seems a little inappropriate to discuss marriage matters. As a result, this matter has been delayed again and again, making the adults of the two families feel a headache.

In the past two years, Qin Hai has been running around the country, and there is not much time to settle down in one place. Under the inspiration of Qin Hai, Tranquility devoted herself to the research of iron-based superconducting materials, and it was a few days and nights to start doing it, and sometimes Qin Hai arrived in the capital, and it was not easy to see her. Afterward. Qin Hai came up with a way, that is, to go to the real yàn room to accompany Tranquility to do the real yàn, and from time to time he was able to give Tranquility some guidance. Calculated carefully, the opportunities for the two of them to go shopping together are indeed a handful, but there are more times when they do real things together.

Sometimes, Tranquility also feels that she is a little lost, others fall in love before and after the moon, Qingqing and me, but she and Qin Hai are circling around a bunch of real equipment. Two of the three sentences spoken by the two are related to superconducting materials. There's no sweet talk at all.

This time, the two of them were finally able to come to Paris at the same time, and they were able to take a leisurely walk on the famous Champs-Élysées, which made up for some of the regrets in Tranquility's heart. However, her ease was only for a short while, after saying a few nonsense about the lack of oil and salt between lovers. The conversation then moved on to the academic aspect.

"Qin Hai, I'm very unsteady now, you say, after I speak tomorrow, what questions will others ask?" Tranquility wept sadly. asked Qin Hai.

Qin Hai stretched out his hand and patted Ningning's head, helped her comb the messy hair on her head, and said with a smile: "How do I know what questions others will ask?" However, as long as you are ready, you can respond to all changes with the same, and what others say is not within the scope of your preparation? Think about it, so far, who in the world has done iron-based superconductivity research more professionally than you? ”

It turned out that the purpose of Tranquility's visit to Paris this time was to read her paper on iron-based superconductivity at the International Materials Annual Conference. Under the guidance of Qin Hai and the financial support regardless of the cost of work, Ning Ning was the first in the entire superconductivity community to discover the superconductivity characteristics of iron-based materials, and a short review she wrote was published in the top international academic journal Nature as she wished, and caused a sensation in the international superconductivity community.

As the discoverer of iron-based superconductivity, Tranquility was invited by the International Materials Society to give a keynote speech on iron-based superconductivity at this annual materials conference. It is said that this opportunity to give a keynote speech has never been given to a graduate student who has not yet obtained a doctorate.

To prepare for this keynote speech, Serenity spent two months writing the conference papers. In this paper, she will not only introduce the phenomenon of iron-based superconductivity itself, but also explore the mechanism behind this superconductivity phenomenon from a physical point of view, for which it is necessary to propose some theoretical models that have not been proposed before.

Although Qin Hai and her mentor Chen Zongze gave her some help in the process of writing the thesis, when the thesis was finally completed, Qin Hai still had to admit that Ningning's attainments in this field had reached a very high level, and it was in vain that Qin Hai handed over the opportunity to discover iron-based superconductivity to her.

"I'm really not steady." "I'm very immature about the model of electron-hole symmetry, and I'm worried that some people will question whether this model is valid. Qin Hai, you said that if someone really raises doubts, how should I answer? ”

"Just answer it your own way." Qin Hai said, "What theory will not be questioned? Even if they are academic authorities at the level of Taishan Beidou, their theories are frequently questioned. It's a good thing that someone questions it, it means that your theory can get your peers thinking, and if they want to write an article questioning your theory, it can also increase your citation rate. ”

"Hee-hee, that's true." Tranquility smiled, the academic circle is very concerned about the citation rate of the paper, if a paper is often cited by other scholars, it means that the paper has high academic value, and then can reflect the academic status of the author of the paper. Even if other scholars cite it for the purpose of questioning or even refuting it, it shows that your article has the effect of throwing bricks and stones, not the kind of waste that can't be heard when thrown into the water.

Qin Hai hopes that Tranquility will become an outstanding scholar, and to reach the peak of academics, this kind of experience of being questioned at top academic conferences is a must, and at the same time, it is necessary to cultivate a psychological element that is not shocked. He personally accompanied Tranquility to attend this annual meeting, hoping to give Tranquility some guidance on the spot and help her cross the threshold from a student to a scholar. He believed that with Serenity's gift, she could do just that.

"Okay, Xiaojing, the conference speech is tomorrow's business, don't think about it now. You see, this street is all selling luxury goods, do you want to pick up a few pieces of jewelry? Qin Hai diverted the topic, pointed to the bejeweled shops on both sides of the road, and asked Tranquility.

Tranquility's face flushed slightly, and she whispered, "Do you want to give me any jewelry?" ”

"No problem, what do you want to buy, I'll pay for you, brother is a big sum now, not to mention that he can buy the entire Champs-Élysées, it is estimated that he can still do it by buying three or five stores." Qin Hainiu said dryly.

Tranquility snorted and said, "What do you mean I want to buy, do you want to give away jewelry, and do you want others to speak for themselves?" ”

"Uh......" Qin Hai scratched his head, suddenly had a flash of inspiration, and hurriedly said: "I'm really confused, it seems that I should buy you a diamond ring, right?" ”

"Why do you buy a diamond ring?" Tranquility asked knowingly.

Qin Hai smiled shyly: "Of course it's a marriage proposal, now even fat people know how to buy a diamond ring and propose, can I fall behind?" ”

"Do you still have the face to say, my brother bought a diamond ring in Pujiang, or did you accompany him, you can't think of buying one for yourself?" Tranquility said with a bit of coquettishness.

The fat man Qin Hai just said was referring to Ning Mo, the quiet elder brother. Last year, Ning Mo had officially proposed to Xu Xiaoqi, and Xu Xiaoqi's parents also made a special trip to Anhe to meet Ning Zhongying and Song Yulan, and agreed to marry them when Xu Xiaoqi came back from studying abroad. Qin Hai spent a lot of energy on Ning Mo's affairs, accompanied Ning Mo to buy a diamond ring, and gave him a lot of ideas. But when it came to him, he seemed a little sluggish.

"Okay, let's go buy it now!" Qin Hai had a good habit of changing when he knew his mistakes, he pointed to the front with his finger and said, "Look, there is a jewelry store over there, let's go over and take a look, pick your favorite and buy it." Don't save money for my brother, my brother is so poor now that he has money left. ”

"You're poor!" Tranquility punched Qin Hai and scolded angrily.

Women are born to like luxury, and as soon as they walk into the jewelry store, Tranquility completely forgets about superconductivity, models and other things. She timidly lay in front of the counter, looking at the dazzling array of rings, necklaces, and so on in the window, lingering. In her opinion, every piece of jewelry is so brilliant that she can't choose at all.

"Excuse me, miss, which piece of jewelry do you like, I can take it out for you and try it on." The clerk of the jewelry store walked up enthusiastically and said respectfully to Tranquility. Although Qin Hai and Ningning's clothes were not glamorous, and they didn't look like they could afford to buy high-end jewelry, the clerks still treated them as honored customers in a proper manner.

"This ...... I don't know! Tranquility's face turned red, and Qin Hai, who was standing on the side, also felt some inexplicable embarrassment, and didn't know what to say. These two people are also among the top richest people in China, but when it comes to buying luxury goods, they are really downright turtles. (To be continued......)

PS: I recommend this book to everyone: "Video Game Empire", the title of the book is a bit misleading, but it is actually written to travel to Hong Kong Island in 79 years to develop the electronics industry. After reading it, I felt that the science and technology aspect was written professionally and belonged to the novels of the Industrial Party. The author's writing is good, the story is fast-paced, the description of Hong Kong Island is also vivid, and the plot of Pao Mei is even more heart-stirring...... You might as well collect it and take a look
