Start as a top student and move towards the stars and the sea

Ning Chen also agreed with Xu Zhou's words. According to Ning Chen's theory, the core elements that can produce superconducting properties in this system are mainly Fe and Se elements.

Okay, Teacher Xu, after I finish studying the potassium-iron-selenium superconducting system, I will try to replace the potassium element. There are too many experiments to do here, and I still have to do them one by one.

It doesn't matter, just take your time. You are still very young. There is plenty of time for you to explore.

Ning Chen didn't feel that he had enough time. Even if Ning Chen spent his whole life on research, it would still not be enough for Ning Chen to explore various subjects.

Ning Chen only hopes that he can enjoy every process of research and leave his own small mark on the long river of human exploration of truth.

…

Unknowingly, time has entered July.

As the experiments continued, Ning Chen's research progress became much smoother than before.

Perhaps it was because Ning Chen experienced too many failures in previous experiments, which allowed Ning Chen to avoid many detours in subsequent research.

In just two weeks, Ning Chen found the second superconductor in this new iron-based superconducting system.

The K element ratio of the second type of superconductor is exactly half of that of the first type, but it also makes the entire phase achieve superconducting properties.

This allowed Ning Chen to further confirm the existence of this superconducting system and conduct detailed measurements and analysis of the second superconductor.

On this day, Ning Chen received messages from Lin You and Song Xiyun on QQ.

The two of them said they wanted to come to Shengzhou to spend a few days together, and asked Ning Chen if he was busy recently, and if it was convenient for them, they could go there.

Ning Chen is indeed very busy every day, but fortunately, Ning Chen can freely arrange his own experimental time, because Ning Chen does not work for the teacher, but is responsible for the progress of his own experiments.

After these days of continuous experiments, Ning Chen really wanted to change his mood a little.

It doesn't matter, just come over here, agree to provide food and accommodation, and never regret it.

Speaking of which, Ning Chen also missed these two friends he had made through mathematics.

On the day when Lin You and Song Xiyun set off, Ning Chen originally wanted to pick them up at the airport, but the two of them may have been afraid of delaying Ning Chen's time, so they repeatedly stressed that Ning Chen could just wait at school, so Ning Chen finally gave up.

After getting off the plane, Lin You and Song Xiyun took a taxi directly to Shengzhou University.

Ning Chen had been waiting at the school gate for a while. Seeing the two people getting out of the taxi, Ning Chen felt a little excited.

But finally the two of you are here. Just like this, we haven't seen each other for several months.

Hehe, we said we were coming to Shengzhou before. How about we keep our word? This time we came to see you specially. It's not like you come here for business every time you come to Yanjing. Let's take a look at it by the way. Us. Song Xiyun said with a smile.

Ning Chen, how are you doing recently, and what topics are you studying?

Recently, I have been studying materials. There is no research direction in mathematics for the time being.

Ning Chen did not have the energy to study another research topic at the level of Qiu Chengtong's conjecture for the time being, so he should continue working on the superconducting material project at hand.

After exchanging pleasantries with Lin You and Song Xiyun, Ning Chen said:

Put your things at my house first, take a rest, and then we'll go to school for a walk.

Lin You and Song Xiyun both came with suitcases, and Ning Chen couldn't let them drag their suitcases around the campus.

Ning Chen brought Lin You and Song Xiyun to Xiangdu Garden Community and walked in. Lin You and Song Xiyun were very envious of Ning Chen's house.

It's not bad. It's so close to the school and the community is so good. And it's such a luxury for you to live alone in such a big house!

There is no way, this community is full of large apartments. But the houses in Shengzhou are cheap anyway. If we were in Yanjing, I would probably only be able to afford one bedroom at the same price.

In this era, the average house price in Yanjing is around 30,000, and the house prices in the city center are even ridiculously high.

Song Xiyun, please stay in the south bedroom at night. It will be very cool if you turn on the air conditioner. Lin You, please stay in the north bedroom. This room is quite spacious.

The south bedroom is the master bedroom of this house. Although the weather will be hotter in summer, Ning Chen thinks it is more appropriate to place Song Xiyun in the master bedroom.

The area of ​​the north bedroom is not small, and it is relatively cooler. Lin You will not be wronged if he is placed in the north bedroom.

Ning Chen, do you want to sleep in the study? Or I can sleep in the study. I don't care.

Lin You knew that the study room was the smallest room, and he was embarrassed to let Ning Chen wrong him.

It's okay. In fact, I usually sleep in the study room. It's very convenient to fall asleep after work. Okay, no need to say more, it's settled.

Lin You thought for a while and felt that there might be a lot of important information about Ning Chen in the study, and it was really not good for him to live there, so he agreed.

You must be quite tired along the way. Do you want to rest in the room for a while?

It's nothing tiring. The flight from Yanjing to Shengzhou is very convenient, and we took a taxi as soon as we got off the plane.

Yes, it's hard to come to Shengzhou. Let's take us out for a walk first.

After putting their luggage at home, the three of them came out of Ning Chen's home and planned to visit Shengzhou University first.

The weather in Shengzhou today is not too hot, and the clouds cover the sun very well. Otherwise, Ning Chen might have to wait until night to take them out.

After walking around the Shengzhou University campus, Lin You and Song Xiyun both felt that there was some gap between the real Shengzhou University and their psychological expectations.

Ning Chen, your Shengzhou University... is quite simple. Lin You said.

Ning Chen heard the meaning of Lin You's words and said with a smile:

Haha, compared to your Yanjing University, Shengzhou University is definitely much worse. But now the environment of Shengzhou University is already good, and all aspects have improved a lot compared to the previous two years.

Ever since Ning Chen won the award in the autumn competition, Shengzhou University has begun to change in all aspects. Ning Chen doesn't know if this has a direct relationship with him.

Well, actually the environment is quite good. Look, there are quite a few squirrels here.

As he spoke, Song Xiyun slowly approached a squirrel that was holding a pine cone and eating it.

The squirrel didn't seem to be afraid of Song Xiyun, and it didn't run away out of fear until Song Xiyun was less than one meter away from the squirrel.

Song Xiyun gave Ning Chen a camera gesture, and Ning Chen immediately understood, took out his Nokia, and took several photos of Song Xiyun and Squirrel.

Ning Chen's photography skills are not very good, but he still has basic photography literacy. When taking pictures, he squatted down to make Song Xiyun's legs very slender.

Looking through the photos Ning Chen had just taken, Song Xiyun also felt very satisfied.

The campus area of ​​Shengzhou University is much smaller than that of Shuimu and Yanda.

The three of them walked around the campus for less than an hour and had already visited almost all the places.

It's summer now, and the three of them are already sweating on their foreheads. Ning Chen suggested:

Let's go have a meal nearby first. You haven't eaten yet since you got off the plane, and it's almost dinner time now.

Ning Chen wanted to take Lin You and Song Xiyun to Jiangshan Yufu. After all, they had finally come to Shengzhou, so he had to be more generous.

At this time, Song Xiyun seemed to suddenly remember something and asked Ning Chen:

Ning Chen, can you cook at your house?

Well, it's okay, but I rarely cook at home. Apart from kitchen utensils, rice, and seasonings, I don't have much food at home.

Although Ning Chen can cook some home-cooked dishes, it is really not interesting to cook at home alone, and cooking and cleaning up the kitchen are very time-consuming. It is better to go directly to the canteen for a quick meal.

Then let's go buy some food nearby and then cook it at your house? Song Xiyun said.

Song Xiyun...can you cook?

Of course, why, don't you believe me?

Song Xiyun did not feel like a girl who cooked delicious food to Ning Chen, but since Song Xiyun took the initiative to propose it, Ning Chen also felt that it was more interesting to her than going out to eat.

Okay, then it's settled. But I told you in advance that my cooking skills are not very good, Ning Chen said.

It's okay, I'll take care of it.

Ning Chen took Song Xiyun and Lin You to a nearby fresh food supermarket, bought ribs, pork, eggs, vegetables and other ingredients, and returned to Xiangdu Garden together.

After returning home, Song Xiyun began to prepare the evening meal.

Soon, Ning Chen realized that Song Xiyun did have a certain level of cooking skills.

Song Xiyun first washed the rice and cooked the rice. When adding water, Song Xiyun measured the water level with her index finger.
