With the sound of military training music, the month-long military training officially began on the playground. All the freshmen stood under the scorching sun with a straight body, a spiritual outlook, and a high fighting spirit.

Listening to the instructor's roar, the students trembled. One by one, they stood like pines, their heads held high, and they did not move at all. Occasionally, if you blink more, you will be greeted by the instructor's sharp gaze.

After listening to the instructor's order to rest, they sat cross-legged with their backs to the wind, beating their shoulders and knocking their legs, and such a precious 15 minutes was the happiest moment for the students.

Every day in the future, the cycle of training is repeated forever, resting, training, resting, and before you know it, time flies by, and most of the military training has passed.

At noon that day, after the instructor gave the command to end the training, like caged birds free, the freshmen ran frantically towards the nearest cafeteria as usual. The noisy footsteps came into the ears of the seniors upstairs, and they understood that the "green hats" were starting a new round of cafeteria grabbing, so they angrily took out their mobile phones and quietly browsed the takeaway while the professors on the stage were not paying attention.

But not every student is so lucky to be able to order takeout under the noses of one professor after another. For example, on a certain floor of the Faculty of Science, in a class that was taking the theory of complex variable functions, a certain boy was bold, quietly took out his mobile phone from under the desk, quietly glanced at Professor Lu who was writing with his back to them, and quietly touched his empty stomach, and quietly looked at the takeaway, and was fascinated for a while.

"Quick, don't look at it, put it away quickly." The classmate next to the boy bumped him with his elbow and said in a low voice.

"What's the matter, this fried chicken is new, can't you let me take a second look?" The boy muttered, hung his head slightly and continued to look.

"No, hurry up and put it away, Professor Lu is here."

"Who are you fooling, he is writing a board book behind my back."

As soon as these words fell, the table in front of him was gently knocked, and the boy was startled, and his eyes moved up along the slender hands, and met the stern gaze of the man in front of him.

"Lu, Professor Lu" The boy's voice trembled in shock.

"If you don't want to go to class, go out." Lu Zhaoyu frowned and said coldly.

"No, no, no, I want to do it."

"It's okay if you don't listen to my class, it's okay if you don't come, but if you can't pass the final exam, it's hard to say." He flipped through the book that the boy had placed on the table again, his eyebrows were cold, "Classmate Wu, have a snack." ”

After seeing Professor Lu walking forward, the boy glared at the classmate next to him and said aggrievedly, "Why didn't you say it earlier?" ”

"You don't believe me." The classmate sighed helplessly.

"It's cold now, who is Professor Lu, my usual minutes are definitely gone." The boy drooped his head, and when he saw that the delicious picture of the new fried chicken on the mobile phone screen was still dazzlingly lit, he poked the screen hard, "What kind of fried chicken are you eating, he is about to be eaten by Professor Lu's gaze." ”

After coming out of the classroom after class, Lu Zhaoyu went straight to the parking lot, and when he passed a canteen, he caught a glimpse of a familiar figure.

The girl in camouflage uniform and with a military green hat was held by the person next to her, and her head was turned sideways to reveal a white neck, and the already distinct jawline looked more obvious, and the girl turned her face slightly, still as white as ever.

He was a little strange, classmate Shu Jin, why wasn't he tanned by military training at all?

That year, Lu Yuxuan spent a week in Lindagang military training, and when she came to bring her food at noon, she complained to him for a long time.

"Brother, I've only been in military training for a week, why is it so dark. Not even sunscreen can save me. ”

"You take off your mask and I'll take a look."

"I'd rather die than pick it, I'm afraid you won't recognize me." The girl waved her hand in refusal.

"If you don't pick it, I won't recognize you. Look at your shiny forehead. Lu Zhaoyu looked at the girl and said casually.

"Go away, I don't want to see you." The girl finished in exasperation and turned her head to the side, not wanting to see someone.

Seeing that his sister was really angry, Lu Zhaoyu took out the things in his pocket and pushed them in front of the girl, "Do you want to?"

The girl still looked out the window and didn't respond, he sighed and asked again: "Really?" Then I'll throw it in the trash. ”

"Give it to me, it's mine." Lu Yuxuan hurriedly put it away, and when she saw that it was the latest sunscreen, it was said to be super easy to use, she accepted it with satisfaction, and sighed that she was no longer afraid of being tanned in military training.

After a long time, I thought of something again, and furrowed two beautiful eyebrows.

So her brother really thinks she's dark, otherwise how would he be so considerate and prepared sunscreen for her.

......

In the blink of an eye, a month of military training passed in the students' gritted teeth and persevered. After two days of rest, the four girls of 402 planned to sleep in the dark in the dormitory and relax completely.

However, on the first night of the break, Shu Jin received a WeChat message from Lu Yuxuan.

19:40 Ms. Lu: Shu Jin, are you free tomorrow afternoon?

Shu Jin: Free, what's wrong with Mr. Lu?

Teacher Lu: You didn't go to Tibet some time ago, I have always longed to go there, but my body does not allow it, so I want to hear you talk about this trip to Tibet, and it should be a dream of my own.

Shu Jin: Okay, I will do it for Mr. Lu.

Teacher Lu: Then I will pick you up at the school gate at 1 p.m. tomorrow.

Shu Jin replied with an OK expression.

After putting down her phone, she suddenly remembered something, got out of bed and rummaged through her luggage, and took out the gift she bought for Lu Yuxuan in Tibet. I've been busy all this time, so I forgot about it, and I can just give this to her tomorrow.

At 1 p.m. the next day, Shu Jin saw Lu Yuxuan standing at the school gate waiting for her from a distance.

"Teacher Lu" Shu Jin walked over and called softly.

"What else is your name Teacher Lu, you have graduated, so you will call me Sister Yuxuan in the future. I'm not a few years older than you. ”

Shu Jin pursed her lips and nodded.

After coming to Lu Yuxuan's house again, Shu Jin handed her the gift bag in her hand, "Sister Yuxuan, this is a gift I bought for you in Tibet." ”

"Bought it for me?" Lu Yuxuan said in surprise.

"Well, thank you very much for tutoring me earlier."

"It's my duty, why are you still so polite."

"It's not polite, it's me expressing my gratitude to you." Shu Jin pursed her lips and was silent for a while before she spoke.

"Okay, then I'll take it." Lu Yuxuan said with a smile. Shu Jin, this girl, I really like her so much.

The two chatted for a long time, and Shu Jin told Lu Yuxuan about the scenery she saw along the way in Tibet, the customs she felt, the culture she experienced, and even some of her Tibetan travel impressions.

Lu Yuxuan, on the other hand, listened carefully, sometimes raising some doubts, sometimes showing excitement, but most of them were immersed in the place she longed for as described by Shu Jin.

This is the first time that Shu Jin has shared her experiences and thoughts with others, and it is also the first time that she has said so much. Su Su kept talking, she didn't feel bored, but gave birth to a trace of joy in her heart.

Finally, it was more than 4 o'clock in the afternoon when the driver sent Shu Jin away. Such an afternoon of conversation successfully brought in the relationship between the two, and gradually transitioned from teacher and student to friend.

After Shu Jin left, Lu Yuxuan couldn't wait to open the gift bag, unpack the box, and was pleasantly surprised to find that it was a prayer wheel. And inside the box, a postcard printed with a picture of the Potala Palace fell out, and a line of delicate words on it came into her eyes.

"If the teacher turns the prayer wheel, the next day will be full of peaches and plums."

Lu Yuxuan picked up the postcard and put it in her hand, looked at it quietly for a long time, and was greatly moved.

Shu Jin, isn't she just a peach and plum of her own.

Lu Yuxuan took a photo of the postcard and prayer wheel and sent it to her brother, and she wanted to show off her good student with him.

......

When the mobile phone vibrate, Lu Zhaoyu was still checking the students' experimental data at the Institute of Mathematics of Linda University.

The man in the white lab coat has a pair of black-rimmed glasses on the bridge of his nose, bent over, holding the mouse in one hand and propping the other on the table. The tall and long figure of the past now looks like a bow ready to fire.

"According to the topological characteristics, your set of data processing is not accurate enough, so redo it a few times."

"And to look at the potential metrics of these datasets, you don't have enough samples to prepare, at least 40 per category."

“......”

One of the three graduate students is a girl, who has been following Professor Lu for more than a year, but she still can't contain her heart, and always looks at him quietly inadvertently.

At this time, when the man speaks, the angular jawline moves up and down, and the sexy Adam's apple rolls up and down. The buttons of the shirt under the slender neck are always meticulously fastened, and with a stern expression, it always makes people feel difficult to approach. And now that the pair of black-framed glasses is worn, covering the eyes with a strong color, and wearing a spotless white coat, the whole person reveals a strong aura of asceticism.

By the time the man finished speaking and turned his gaze to the three students, the girl had already retracted her gaze.

"You keep doing it." After Lu Zhaoyu finished speaking to them, he walked outside the laboratory.

took off the white coat on his body, he picked up his mobile phone and looked at it, it was Lu Yuxuan's WeChat not long ago, and the content of this WeChat made him really cry and laugh.

16:30 Lu Yuxuan: You can't get a good student like Shu Jin, hmph.

He clicked on the image below. The ordinary sentence on the postcard, pretending to be a prayer wheel, is actually Shu Jin's best wishes to Lu Yuxuan, and what is even more outstanding is that she is also one of the peach and plum.

For a teacher, this Shu Jin is indeed a rare good student, no wonder Lu Yuxuan likes to be like this, and deliberately shows off to him.

He frowned, knocked on the screen of his mobile phone for a while and replied to Lu Yuxuan: Who said I couldn't get it?
