Lu Qingyi explained very quickly, but he said it very carefully. Luo Xinxin followed Lu Qingyi''s ideas and understood them all at once.


    Sure enough, hardcore''s most famous Professor Lu''s title is not in vain. It must be superior in ability.


    "You''re great."


    After Lu Qingyi explained, Luo Xinxin looked at Lu Qingyi with the test paper and his eyes were full of admiration.


    Other professors have also talked about this problem. The method is not as simple as what Lu Qingyi said. She just understands it.


    Lu Qingyi said that. She understood everything.


    "Average."


    Lu Qingyi took the pen and turned it to play. His voice was slightly cold.


    She didn''t think it was powerful. It was a normal thing. She was used to it and didn''t think it was powerful.


    A simple math problem, in her eyes, is just a pediatric thing, not worth mentioning.


    "Are your genes like this?"


    Luo Xinxin looked at Lu Qingyi curiously and asked, Lu Qingyi is so powerful that the people in her family should be no worse.


    I really envy you.


    "I don''t know."


    Lu Qingyi''s voice was slightly cold.


    family?


    How does she know?


    Li Xiyi walked into the classroom with a thermos cup in her hand. She looked at the direction of Lu Qingyi and Luo Xinxin in amazement.


    No, what''s going on?


    Lu Qingyi came to school, but why did he stay with Luo Xinxin?


    "May I call you sister Qing? I see some people call you that."


    Luo Xinxin gently bit her lower lip. She opened her mouth and asked about her relationship with Lu Qingyi. She wasn''t sure she could call it that.


    Also feel very embarrassed.


    "Whatever."


    Lu Qingyi''s voice was lazy and indifferent.


    She always calls such things casually.


    "Qingyi, have you come to school to make up for your sleep again?"


    Li Xianya walked towards Lu Qingyi. She asked with a slight smile.


    Lu Qingyi came to school mostly sleeping. No professor would take care of Lu Qingyi. She was about to doubt whether Lu Qingyi came to the classroom to make up for her sleep because she couldn''t sleep.


    Students often have insomnia, but the teacher''s voice in class has a special hypnotic effect. It makes people want to sleep.


    Now the university is not too big. In the past, when I was in high school, I felt very deep. I often couldn''t sleep in the middle of the night. I was also very energetic before class during the day.


    As soon as the teacher has class, people begin to feel sleepy and want to sleep. After class, they are full of energy.


    "Well, today is because of boredom."


    Lu Qingyi lazily lifted his eyelids and said carelessly.


    I just woke up. I don''t feel very sleepy now. I just feel a little bored.


    "I just bought a novel. Do you want to read it?"


    Li Xianya asked. In fact, she likes reading novels very much, but she doesn''t have much time to read them. She just met a favorite novel in the bookstore before and bought it. Now she has read half of it.


    Life in college is actually busy. Unlike what the high school teacher said, now you work hard and survive the college entrance examination, the university will be relaxed.


    But is college really easy? Of course, it''s not easy, unless you just want to spend four years in college.


    College is even busier than high school. Sometimes, it''s not easy at all.


    "Ah, all right."


    Lu Qingyi nodded and said that she would never refuse to treat the novel. As long as it suits her appetite, she reads it, and she doesn''t pick the type of novel.


    Campus romance, urban romance, martial arts novels, fantasy novels, science fiction, suspense novels


    Of all types, she is basically fast, except those whose writing is too childish and poor.


    "Here you are."


    Li Xianya took the romance novel from her seat and handed it to Lu Qingyi.


    Lu Qingyi glanced at the cover and title of the book, slightly raised her lips, and began to look at the pages. She always had a lot of enthusiasm for books.


    Luo Xinxin sat aside. She watched the interaction between Li Xianya and Lu Qingyi and slowly bit the corners of her lips.


    Yes, Lu Qingyi likes novels.


    "Luo Xinxin, why are you so close to Qingyi?"


    Li Xianya kicked Luo Xinxin''s stool and asked, her hands around her chest, looking very curious.


    Last time I lost the bet with Lu Qingyi, Luo Xinxin seemed to disappear in Lu Qingyi''s sight. Now why are you sitting next to Lu Qingyi?


    Luo Xinxin bit her lips tightly. She touched her face and said, "can''t you ask questions?"


    Li Xianya: "


    No, you ask questions and go to the teacher. What''s going on sitting next to Lu Qingyi?


    She still remembers that Lu Qingyi took the place of Wei Song in a class before. That class was very good, and everyone in the class felt very good.


    As long as Luo Xinxin feels unconvinced and doesn''t want to listen at all, how can he ask Lu Qingyi questions now?


    "Why don''t you go to Professor Wei?"


    Li Xianya stared at the math paper in Luo Xinxin''s hand. She slowly asked.


    Wei Song teaches mathematics well, but he is much inferior to Lu Qingyi.


    "Wei song should be dating."


    Lu Qingyi bowed her head to read a book. She suddenly said something without a head. Her voice was very cold.


    Li Xianya: "


    Luo Xinxin: "


    Is Wei Song dating? This is not the point. The point is how does Lu Qingyi know that Wei song is dating?


    Lu Qingyi lowered his head. Naturally, he didn''t see the curious expressions of Luo Xinxin and Li Xianya.


    "Sister Qing, how do you know?"


    Luo Xinxin is willing to believe Lu Qingyi in her heart. Even if Lu Qingyi is really just a guess, she is also willing to believe it.


    "That''s the truth. I believe there will be photos in his circle of friends soon."


    Lu Qingyi''s voice was flat and light, without ups and downs to Yu. It was like saying that I had dinner today.


    Li Xianya: "


    Luo Xinxin: "


    No, no? You can even guess that your circle of friends will send photos?


    Because Lu Qingyi doesn''t like joking, they think what Lu Qingyi said should be true.


    It seems that I haven''t seen Wei Song for many days. Other teachers helped replace him in class. I didn''t come.


    Because Wei song is their counselor, most of the students in the class add Wei Song''s wechat, and the circle of friends can naturally see it.


    "Sleeping trough, isn''t it?"


    "My God, it''s really great."


    Luo Xinxin and Li Xianya hurriedly click into Wei Song''s circle of friends and refresh it. There are no new developments in the circle of friends.


    The two men looked at each other and shook their heads silently.


    A few minutes later, Luo Xinxin and Li Xianya re entered the circle of friends again, and the striking characters appeared in front of them.
