"Xiaoxiao, where have you been, we have been looking for you for a long time." Wu Huan saw the girl walking towards him, and hurriedly went up and pulled her to her.

"I've been breathing outside the snack street for a while, and I'm going to wait to come to you." Shu Jin pursed her lips and didn't tell the truth.

"The second and third children went to look for you, I stayed where I was and waited for you, we sent you a lot of messages and you didn't reply, which made us a little worried."

"Boss, I'm sorry for worrying you." Shu Jin said in a low voice, with a hint of apology.

"I'm sorry to say anything, you're fine." After Wu Huan posted a message in the group, he put his arm around the girl's thin shoulders and walked forward.

ran into Zhao Shuang and Gan Xin head-on, and when the two saw that Shu Jin was doing well, they both breathed a sigh of relief.

That night, Shu Jin had a dream, in which some people frowned and disliked her, saying that she was grass; Someone else looked at her seriously and said that she was priceless. She tried to open her eyes to see the man who said she was priceless, but she couldn't see it clearly, only catching his deep voice, the phrase "You are priceless" always echoed in her ears.

......

After Shu Jin collected all the advanced math assignments sent down, he planned to send them to Professor Lu's office while there were no classes in seven or eight classes.

Standing in front of his office door knocked several times, but no one responded, Shu Jin pursed his lips and turned the doorknob, only to realize that the door was locked and no one was inside.

Shu Jin lowered her eyes and took out her mobile phone and sent a WeChat message to Lu Zhaoyu: Professor Lu, I sent the homework to your office, but you are not there, should I take it back first or put it in front of the window of your office?

After the message was sent, there was no reply for several minutes, Shu Jin pursed her lips and decided to take it back first.

When she walked out of the building of the Faculty of Science, Professor Lu replied to her: Do you have a class later?

Shu Jin: No

Prof. Lu: Then you bring all your homework and come to the Institute of Mathematics of Linda University, and I will share the address with you.

Shu Jin: Okay

Professor Lu: Tell me when you arrive, and I'll go down and pick you up.

Shu Jin: Okay

When Shu Jin was almost there, she sent a message to Lu Zhaoyu, and when she appeared at the door of the research institute, she saw that the man was already waiting for her.

That was the first time Shu Jin saw Lu Zhaoyu wearing a white coat and a pair of black-framed glasses, elegant and elegant, revealing a scholarly atmosphere.

"Come in" Lu Zhaoyu opened the door for the girl, and then led her up.

The three graduate students saw that Professor Lu looked at their mobile phones and said to them, "I'll talk about it later", and then turned around and left.

It was a little strange to see him come back so soon, and when they saw the girl following him, the three of them were already stunned, and they all thought: What is the situation???

Lu Zhaoyu took the girl to the empty table on the side and instructed her: "I'm very busy today, I'll send you the answer later, you sit here and correct the homework in your class, count the error rate of each question, list the questions that more than half of the people are wrong, see if you can solve it, if you can't solve it, I'll explain it to you later, after you understand, write down the detailed solution process and show it to me, and then send it to the students in your class if it's okay." ”

Shu Jin nodded silently after watching him finish speaking.

"Sit down and start." After the man finished speaking, he turned around and walked in, continuing to instruct his three graduate students.

From time to time, the only female graduate student turned her head to look at the girl sitting upright in the corner outside, writing something with a pen. Thinking: What is the relationship between this girl and Professor Lu?

Shu Jin corrected her homework, and after counting the error rate, she was studying the questions she had done wrong, and she took a pen and scribbled on the scratch paper for a long time, but the results were still different from the answers. So I started from scratch.

When Lu Zhaoyu came over, what he saw was that the girl looked at the scratch paper with her eyes down and didn't move for a long time.

Walking in and looking at the question on the scratch paper, he sat down next to the girl, picked up the pen on the table, and said to her, "This question is difficult, you won't be normal." ”

"The first part of your process is right, and the wrong part is here." Lu Zhaoyu circled a place on the scratch paper with a pen, "The correct should be this solution." ”

Watching Professor Lu continue to write down the process of solving the problem on her basis, Shu Jin slowly understood.

So Shu Jin asked him to explain the remaining two questions to her at the same time.

Seeing that the girl listened carefully and could answer his questions from time to time, Lu Zhaoyu couldn't help but praise: "It seems that you can improve your math level." ”

"What level I was before." Shu Jin pursed her lips and asked in a low voice.

"Want to know?"

"I kind of want to." The girl nodded and said honestly.

Seeing the girl looking at her with a serious face, Lu Zhaoyu was moved in her heart.

"I once had the pleasure of reading your three-mold roll, and I gave you a three-word evaluation at that time."

Shu Jin looked at him with wide eyes, waiting for him to continue.

"Poor level," the man's thin lips slowly spit out three words.

"......" Shu Jin pursed the corners of her lips, looked away from his face, and looked away.

Every time he spoke, she always looked at him fixedly, and now she was shy? Is this what a little girl is shy?

Suppressing a trace of joy rising from the bottom of his heart, Professor Lu had the idea of teasing for the first time.

"Shu Jin, it's rude for others not to look at each other when they speak, you have always been a polite person, what are you doing?"

Shu Jin listened silently, and slowly turned his head back, looking at him with a somewhat unnatural look.

"Is my assessment going too far, or are you embarrassed?"

As soon as the man's words fell, he saw that the girl's white ears gradually began to dye pink, and he couldn't help but hook the corners of his lips.

I thought: interesting, so interesting.

What Professor Lu didn't know was that when he was lecturing Shu Jin outside, he also lowered his voice and exploded inside.

"Wocao, who is that girl? The first time Professor Lu brought someone to our institute was a girl! The tall boy whispered to the other two.

"Yes! Professor Leng Mian actually likes this kind of petite and delicate girl? The other shorter boy replied.

"What are you all thinking, maybe this girl is a relative of the professor." The only girl interjected.

"You see, Professor Lu is holding a pen and saying something to her, maybe this girl is really a relative, maybe she is his student like us." The tall boy said again.

"When you say that, I think it's very likely that you're a student." The shorter boy also answered.

“......”

By the time Shu Jin wrote all the problem-solving processes and gave Lu Zhaoyu a look, it was already 17:45 in the evening.

Shu Jin was thinking about leaving, but was stopped by Lu Zhaoyu: "I've worked hard for you in the afternoon, wait for us for a while, I'll take you to dinner." ”

Without waiting for Shu Jin to express his position, he walked in again, and he didn't know what he said, and there were excited cheers from inside.

After the three graduate students came out, Lu Zhaoyu lightly introduced Shu Jin to them.

Tall boy: I don't have to say how good this girl looks.

Shorter boys: Petite and delicate like a rag doll, really good-looking.

The only girl: She looks good, but she doesn't look easy to get along with.

The four of them followed Lu Zhaoyu to the parking lot, and when they saw that the girl was going to sit in the back, he pointed to the co-pilot: "You go to the front." ”

The girl pursed her lips and nodded, opened the door and sat inside.

On the way, Lu Zhaoyu drove smoothly and asked lightly: "What do you want to eat?" ”

Tall boy: "The professor has a treat, you can eat anything, I don't pick." ”

Short boy: "I'm casual." ”

The only girl: "Listen to Professor Lu." ”

Only Shu Jin didn't speak, and Lu Zhaoyu glanced at her lightly: "Shu Jin, what about you?" ”

The girl who was ordered pursed her lips and was silent for a long time, looked at the man and said, "McDonald's"

"......" three graduate students, this girl is too upright.

Professor Lu frowned, and said to the girl with some seriousness: "Eat less junk food." ”

Shu Jin nodded instructively, pursed the corners of her lips and did not speak.

Lu Zhaoyu glanced at the little girl, and said the next second: "But it's okay to eat once in a while." ”

"......" three graduate students, this is their serious Professor Lu??

The man looked at them again in the mirror and asked, "Do you have any opinions?" ”

The tall boy hurriedly waved his hand: "No, no, I haven't eaten for a long time, I miss it a lot." ”

Short boy: "Absolutely not, I've loved McDonald's since I was a child." ”

The only girl: "No." ”

When the five of them entered the McDonald's store together, the three graduate students were still in disbelief.

"Want something?" After sitting down in his seat, Lu Zhaoyu looked at the four of them and asked.

"We all eat." The three graduate students looked at each other and replied.

Lu Zhaoyu nodded and looked at Shu Jin, intending to ask her.

Shu Jin pursed her lips and said in a low voice: "Big Mac burger, Colonel chicken nuggets, Coke." ”

"......" three graduate students admired this girl.

"That's it?" Lu Zhaoyu frowned.

After seeing Shu Jin nodding, Lu Zhaoyu got up and went to order.

As soon as Professor Lu left, these people talked to Shu Jin one after another.

Tall boy: "Senior sister, this is for you." He gave the girl a thumbs up, "You're so powerful that you ignore Professor Lu's majesty." ”

The short boy chimed in: "Yes, senior sister, aren't you afraid of the professor?" ”

Shu Jin looked at them and shook his head.

"But after the incident of the senior sister, I found that our professor is quite understanding, and I am suddenly not so afraid of him, after all, he can eat this kind of junk food for students." The only girl looked at them and said.

"Yes, Professor Lu invited us to dinner for the first time, I was really flattered, I didn't expect it to be so easy-going, and McDonald's was willing to eat."

Lu Zhaoyu came back with a plate and motioned for the two boys to bring the rest.

"Coke is too icy, I changed the milk for all of you." Lu Zhaoyu said lightly.

"Thank you, Professor Lu." They were shocked, Professor Lu was simply more intimate than he had ever been, and when they looked at this table full of food, their hearts were moved again.

The tall boy ate the spicy chicken in his hand, and from time to time he looked at Shu Jin opposite, and always felt that this girl was very familiar. Suddenly, as if thinking of something, he asked her in surprise: "Senior sister, did you perform the guzheng at the New Year's Day party last year?" ”

Shu Jin raised her eyes, pursed her lips and looked at him, and was about to say something, but was interrupted by Lu Zhaoyu with some displeasure.

"Sleep is silent, food is silent."

"......" Shu Jin, she almost forgot Professor Lu's rules.

"......" The tall boy's heart trembled, his hand shook, and he almost shook the spicy chicken to the table.

"...... "Short boy and the only girl, Professor Lu is really still the same Professor Lu!"
