After Professor Liu finished speaking, everyone's eyes fell on Luo Suian.
However, she herself didn't know it. At this moment, she was immersed in calculations and couldn't hear the outside world at all. It was only when Ye Yixing's classmate called out that she came to her senses.
"What's wrong?" she asked Ye Yixing in a low voice.
Ye Yixing: "Professor Liu asked you to get up and answer questions."
Luo Suian:!!
What question is she answering? She is not a student of Beijing University.
Luo Sui'an thought Professor Liu didn't see it was her, so she quickly stood up and shouted: "Professor Liu."
"Well, tell me, why does the universe appear to have one time dimension and three space dimensions?" Professor Liu nodded and began to ask questions.
Luo Suian:??
Who will tell her first what is the time dimension and what is the space dimension?
And Professor Liu, are you too far away to see clearly who I am?
Luo Suian was so embarrassed that she quickly pulled Ye Yixing's clothes and asked him what to do with her eyes.
Ye Yixing took her hand and stood up: "Professor Liu, let me answer this question."
"Oh?" Professor Liu asked knowingly: "Why do you want to answer for this female classmate?"
Ye Yixing said: "She is not a student in our department, she is my girlfriend, she just came to accompany me to class today."
Luo Suian's face suddenly turned red and he wanted to take his hand out of Ye Yixing's hand, but he held it tightly.
Professor Liu laughed and said, "It turns out that our cool male idol from Peking University already has a master. Okay, I'll give you a chance to be a hero and save the beauty. You can answer it."
Ye Yixing then let go of his hand and asked Luo Suian to sit down and answer the question by himself.
Luo Sui'an was completely dizzy. She couldn't understand a word of what Ye Yixing said, but... she didn't know how serious it was.
Ye Yixing is indeed a god of learning and knows a lot.
She looked up at Ye Yixing. Ye Yixing occasionally lowered his eyes and caught her eyes, curled his lips and smiled, and the entire lecture hall became much brighter.
The few girls in the Department of Physics were so envious. What kind of fate was this? They actually got Ye Yixing. After the class, Luo Sui'an was in the Physics Department of Peking University. No, she became famous in Peking University. Photos of her and Ye Yixing
It’s all over the place in various WeChat groups, even on school forums, everyone knows that Ye Yixing is in a relationship with his girlfriend
Friend is super pretty.
Luo Sui'an didn't know this at all. After class, she followed Ye Yi out of the classroom and whispered: "Professor Liu loves to joke too much and pretends not to know me on purpose."
Ye Yixing chuckled: "He is just an old naughty boy, just teasing you."
Luo Suian was speechless and asked him: "Shall we go back now?"
Ye Yixing looked at the time: "Let's go to the library. I'll take you to the cafeteria for lunch."
Toolman Luo Suian said he had no objection.
The two went to the library, and as expected, they became the focus of the crowd again. All the classmates who were reading seriously were now looking at her and Ye Yixing.
"You read the book first, and I will correct the paper for you." Ye Yixing took away the math paper she had finished and stuffed a book into her.
Luo Sui'an's head hurt from doing the papers, and she really didn't want to read at the moment. She said, "Can I draw some pictures to change my mind?"
"Okay, let's draw." Ye Yixing followed her.
Luo Sui'an felt like he was being pardoned. He took a piece of white paper and a pencil and started sketching. One of the two of them was seriously correcting the paper, and the other was seriously drawing. They didn't do anything intimate, but for some reason, they stared at the others.
