In two years, Xu You graduated before he had a good experience of campus life.

Fortunately, in the next time, Xu You only changed his identity to a doctoral student, and there was no essential change in other aspects.

Wearing a bachelor's uniform, Xu You returned to dormitory 208.

Xu You didn’t have any special thoughts, just wanted to go back to the dormitory to replace this bachelor’s uniform.

Xu You was not interested in taking graduation photos.

Those who take graduation photos are seniors in their seniors.

Xu You will inevitably appear out of place here.

When Xu You returned to the dormitory, his roommates were mixed with emotion when they saw Xu You wearing a bachelor's uniform.

The roommates must be happy for Xu You to graduate from undergraduate two years ahead of schedule.

At the same time, they also envied Xu You very much.

While they were still busy with the final exam of their sophomore year, Xu You actually had to get his undergraduate diploma.

In addition, they also knew that after this, Xu You should move out of dormitory 208 and go to the graduate dormitory.

"Xu You, are you back to pack up?"

"Pack up things? Oh, by the way, let me tell you a message. I applied with the school and I won't move out of this dormitory in the future. So even if I graduate school, we will still be roommates."

Upon hearing this news, Liu Rui, Guo Haochen and Zhao Xiaohui all laughed excitedly.

"Then we can be roommates for two years? That's great!"

Although Xu You does not often stay in the dormitory after renting a house.

But as long as Xu You's luggage is still left at 208, that feeling is completely different.

"Hey, Xu You, have you taken graduation photos?" Liu Rui asked.

Xu You shook his head and said, "No, I have nothing to take photos alone. You can't just take selfies. This is just a ceremony, it doesn't matter."

"That's not possible. This is a very memorable moment in life. You can't just miss it. Let's take a photo with you!"

"Will that not delay your final review?"

"It's okay, it won't take a few minutes, right?"

Guo Haochen and Zhao Xiaohui also nodded in agreement.

Such a moment is indeed worth remembering.

Not to mention, I took a photo with someone like Xu You.

"By the way, Xu You, call your female classmate too. She must not want to miss such an important moment."

"Does Lu Zhiyao... Then ask her."

Xu You didn't know if this would disturb Lu Zhiyao.

But if you don’t tell Lu Zhiyao, it seems that you are not a friend enough.

Thinking of this, Xu You sent a message to Lu Zhiyao on WeChat.

[Xu You: I have finished my graduation ceremony. Do you want to take a few photos together and leave a souvenir?]

[Lu Zhiyao: I want it, you must be lonely after graduation, right? Just let the cat be a companion. ω]

[Xu You: I almost forgot if you didn't say it. Then I'll call you later, and a few of my roommates will be with you]

【Lu Zhiyao: OK, see you later】

After a while, Xu You and others came outside.

Liu Rui specially brought his SLR camera to present better photos.

Xu You called Lu Zhiyao on WeChat.

Soon, Lu Zhiyao came downstairs.

"Sister-in-law is so beautiful..." Liu Rui couldn't help but sigh.

Today, Lu Zhiyao looks particularly beautiful, and the makeup on her face is just right.

It was also the first time that Lu Zhiyao officially appeared in front of Xu You's roommates, a little shy.

"Come on, let's take a few photos for you two first."

As he said that, Xu You and Lu Zhiyao took many photos together.

Xu You still remembers that in high school, both of them had the dream of passing Ji University.

This dream that sounded a bit out of reach at the beginning.

Now, it has become a reality.

Next, several people took many photos in various memorable places in Jida.

Including the cats downstairs of Lu Zhiyao's dormitory, they also took several photos with everyone.

After returning to Heqing Academy, Xu You remembered Dean Jiang Hong and instructor Sun Bingkun.

In the past two years, the dean and instructor have also provided a lot of help to Xu You.

Xu You also took photos with them separately.

And when the students of Heqing Academy knew that Xu You had graduated.

They all found Xu You and wanted to take a photo with Xu You.

Xu You had no reason to refuse this.

It was fine at the beginning, and I could join in one photo after another.

Later, as the number of students increased, I could only take photos with multiple people.

...

After finishing graduation.

Xu You can finally re-invest his energy in superconductor projects.

With the calculation results of batches of superconducting substances released.

More and more superconductors are being discovered.

And their superconducting critical temperatures are constantly setting new records.

From 160K, to 170K, to 180K…

These remarkable discoveries have made high-temperature superconductors no longer rare.

Xu You was also waiting, and the first superconductor to break through the dry ice sublimation point appeared.

finally.

In the calculations of the fifth batch, everyone discovered.

The critical temperature of a substance's superconducting substance reaches an astonishing 200K.

"200K! It has broken through the sublimation point of dry ice!"

After more and more high-temperature superconductors are discovered.

This news is undoubtedly a more shocking news.

Although the 200K is only 5K higher than the 195K.

But this is a qualitative leap.

If this substance can be really prepared and put into application.

That will standardize that superconducting technology will move towards a new era-

Dry ice age!

Using dry ice as a refrigerant will greatly reduce the cost of superconducting.

Even this cannot allow superconductors to enter the lives of the public.

But for many industries, this is definitely a technology that has great value.

"The research on other superconducting materials can be paused first. Let's focus all our current energy on the preparation of this new material."

In contrast, those superconductors with critical temperatures below 195K before now seem less important.

After all, the difference between whether the temperature threshold of 195K can be exceeded is really huge.

After learning the news, the professors on the team were also very excited and looked forward to it, and focused on the preparation of this new material.

With previous experience in preparing these materials.

It is not that difficult for everyone to prepare new materials.

Because these superconducting materials are structured similar.

The difficulties encountered in the preparation project are also relatively similar.

This time, the time for the successful preparation of new materials is even shorter than those before.

After completing the preparation of the materials, everyone came to the Xida Condensed Matter Physics Laboratory again.
Chapter completed!
