Chapter 166: Convenience turned into real convenience

Xu Qingzhou looked at Song Yao. To be honest, he was very surprised. He originally just wanted convenience, intending to rent a house outside the school and make do for a night if he couldn't return to the dormitory. Who knew it would suddenly turn into a co-pfft—a shared rental.

Heaven is my witness, although he wanted to turn the girl in front of him into a long-term dining companion, he really hadn't thought about moving out together now.

Hehe, unintentional planting of willows, willows grew into shade; convenience turned into real convenience.

Song Yao also looked at him, her expression still cold and clear, without the slightest change, as if it were really the case, but her heart was beating thump-thump uncontrollably.

She recited silently: Song Yao, don't panic, don't look like you're coveting something of his. It's still Auntie Wang's entrustment to keep an eye on Xu Qingzhou so he doesn't stay up late all day and overdraw his body.

After all, they were high school classmates, friends, and dining companions; she couldn't bear to watch him die young.

Most importantly, Song Yao's crystal-clear eyes condensed. This guy's mouth was almost unable to be suppressed.

Xu Qingzhou tidied up his seat for Song Yao to read, then put on his white lab coat in a few quick movements. After putting it on, he saw Song Yao staring straight at him. "Is there something on my face?"

Read! {

Xu Qingzhou restrained his expression and said seriously, sighing in his heart again: push the boat with the current, and then let things take their course... perfect.

A freshman was talking eloquently, and a senior sister was listening to the lecture on the side.

The moment he started, his entire temperament changed.

At this time, Xu Qingzhou had already finished eating. After tidying up the lunch box, he said to Song Yao: "I remember you have a class in the morning. Are you planning to go directly to the classroom, or stay here for a while?"

"Senior Sister Ren, hello." Song Yao nodded and greeted.

Ren Xiaoling was recording on the side.

"Know, know, Junior Sister Song Yao, the school celebrity."

Ji Yunshi also had a strange expression. Although Little Zhong had already said that there was no problem with Xu Qingzhou here, he still wanted to come and see, and as a result, he saw such a scene.

Laboratory.

This step was quite troublesome. First, the crystal had to be fixed with a fixer. This wasn't the end; because the BIBO crystal had a birefringence effect, it was necessary to carefully adjust the direction of the crystal to ensure that the pump light and signal light satisfied the phase-matching conditions inside the crystal.

Xu Qingzhou spent 40 minutes cutting, grinding, and polishing the crystal.

Seeing Ren Xiaoling had nothing to do, Xu Qingzhou said: "Senior sister, I have already brought the samples back. They are in the sample box. You take them to the cutting table first, and I will come to cut them later."

!.

Song Yao moved her gaze away, curled her lips, and said: "You go in quickly, don't disturb my reading."

Perfect.

Before starting, Xu Qingzhou explained to Ren Xiaoling: "I will place the crystal on the pump light path to ensure that the pump light can effectively couple into the crystal and undergo nonlinear interaction."

He exhaled and focused his attention on the experiment, starting to debug the equipment: "Start debugging the mode-locked femtosecond pulsed laser now. Value: center wavelength 815nm, pulse width 130fs."

Ren Xiaoling coughed lightly at the door, feeling speechless in her heart. The news she heard this time was even more explosive: the junior brother was actually going to live with Song Yao! This was only freshman year; what kind of fairy love is this! Xu Qingzhou ate his breakfast of love and asked Ren Xiaoling: "Senior sister, have you had breakfast?"

"See, Director, there's really nothing I can help with here." Zhong Xiaodong's expression was complex. Look at this person's operation; it was simply more standard than a doctor like him.

"If it's a two-bedroom... Yandongyuan is not bad, the environment is okay. Wait... next month, let's go see."

Looking through the laboratory glass, in front of the machine, Xu Qingzhou was wearing a white lab coat, wearing goggles, his eyes focused, operating a polishing machine, completely different from his usual sloppy appearance. Song Yao couldn't help but be a little dazed. After thinking about it, she took out her phone and secretly took a picture.

Both were very serious and didn't notice that there were two people standing outside the laboratory. "Okay." Ren Xiaoling was full of drive and had been looking forward to today's experiment. Yes, her roommates, a few days ago... Physics and mathematics were different, especially experiments. Mathematics could be overturned and restarted if a decimal point was wrong, but physics experiments... Heh, they didn't know at all how amazing this junior brother was!

"Cough~"

"My friend, Song Yao from the School of Economics. This is another member of the laboratory, Senior Sister Ren Xiaoling, now a senior." Xu Qingzhou introduced the identities of the two girls respectively.

Next, the BIBO crystal was installed in the resonant cavity of the synchronous pump optical parametric oscillator.

If he covered his face, he would have thought he was some old professor.

Song Yao got up, tidied up her things, carried the plastic lunch box, and prepared to go directly to class.

Ren Xiaoling greeted with a smile and looked at this junior sister, who was known as the Iceberg Goddess, at close range. She felt a sigh in her heart. Too beautiful, no wonder the boys in the forum were discussing it; even she, a girl, was a little moved.

Every step was meticulous and very rigorous. Although she had heard a lot of experimental knowledge from this Junior Brother Xu during this time, this was the first time she saw Xu Qingzhou do it herself.

Ren Xiaoling and Song Yao waved their hands and entered the laboratory.

"Oh, okay." Ren Xiaoling nodded hurriedly. Unknowingly, she had already placed Xu Qingzhou in the position of those professors.

On this side, Xu Qingzhou realized that Song Yao had already left.

Looking at the photo, Song Yao nodded slightly. Although this guy was handsome when he was serious, but... it was mainly her photography skills that were good.

How to describe it? It was the kind of halo on his head that made people feel like worshipping.

Song Yao also exhaled, took out her notebook, and read quietly.

Ren Xiaoling put away her emotion and took a pen to record.

"I'll read here for a while, you get busy, don't worry about me."

"Already ate." Ren Xiaoling walked in.

However, looking at the boy in the laboratory, Song Yao felt a little depressed again, feeling that the gap between herself and Xu Qingzhou was getting bigger and bigger. She shook her head, took a deep breath, secretly cheered herself up, lifted her feet, and strode toward the library.

Heh, maybe he had been plotting for a long time, so she would just be a little prey for once.

"Hmm." Song Yao nodded, feeling quite happy in her heart. Today was already the 27th, and it would be next month soon.

It was the first time seeing this guy in a white lab coat. Xu Qingzhou smiled and slipped into the laboratory.

In this process, as long as the rotation angle and tilt angle were slightly tilted, the data would deviate.

Xu Qingzhou shook his head and reminded with a smile: "Don't worry about recording yet, look at the installation steps clearly."

30 minutes passed.

"I think they might really be able to produce good results." Zhong Xiaodong whispered. The difficulty of this experiment was very high, even more complex than the project his supervisor was currently conducting.

Ji Yunshi had the same feeling, but still smiled and said: "Undergraduates can push this project forward; whether there are results is not that important."

It would be better if there were results, and it wouldn't be in vain for them to handle special matters specially and be criticized for wasting the country's resources.

The two stared outside the laboratory for another two minutes, and Ji Yunshi left. Before leaving, he specifically urged that if Xu Qingzhou needed any assistance, satisfy it as much as possible.
