She is wearing a gray windbreaker, a red and white checked scarf tied around her neckline, her golden hair is randomly scattered behind her, her ears are wearing a fluffy cat earmuffs, the corners of her mouth are upturned, with a touch of playfulness. , It looks both charming and innocent.

Looking at Oylin, Qin Luo's "On Contradiction" appeared in Qin Luo's mind. Oylin was a combination of contradictions.

"Should I call you Classmate Qin now? Or should I call you Professor Qin." Regardless of whether Qin Luo would refuse, Ou Yilin pulled away the stool opposite Qin Luo.

Student Qin or Professor Qin?

Qin Luo took a serious look at Ou Yilin, and said, "Which university are you going to take?"

Oylin:? ? ?

"What do you mean?"

"If you want to take the test of Yan University, you must call me Professor Qin." Qin Luo paused: "If you don't take the test, you still have to teach me the professor."

Qin Luo thought about it seriously. Whether Oylin is studying at Yanjing University or not, his status as a professor is always there, and it will not change because of Oylin.

"..."

So and so, give me a knife.

Oylin has the urge to chop people.

You have to ask whether you take the test or not. What does this have to do with saying or not?

Oylin resisted the urge to hack someone, glanced at the notebook on the table, and said, "Student Qin is studying Professor Chen's paper?"

"En." Qin Luo nodded and said: "I am studying the possibility of using Professor Chen's theory to solve Riemann's conjecture."

Oylin staggered and almost didn't fall to the ground!

"Student Qin, are you sure it's Riemann's conjecture? A conjecture proposed by mathematician Riemann?" Ou Yilin gritted her teeth and asked.

"Any other conjectures besides it can be called Riemann conjecture?" Qin Luo thought about it seriously. In his impression, there seems to be only one Riemann conjecture.

Oylin has the urge to hide her face and run wildly, bullying people, it is too bully.

How can Riemann conjecture after opening his mouth? Can you still speak well?

"..." Oylin's mouth twitched, she took out a piece of chewing gum from nowhere, and handed it to Qin Luo: "Professor Qin, do you want a slice?"

He bit his words very hard, desperately suppressing his inner anger.

Uh……

Looking at Ou Yilin's green face, Qin Luo hesitated for a while, stretched out his hand and pulled out a piece: "Thank you..."

Although Qin Luo's childhood education was not to accept food from strangers, there was a story between himself and Oylin. It should be okay to accept a piece of chewing gum from her?

Thinking of this, Qin Luo removed the candy wrapper and put the chewing gum into his mouth.

Lemon taste, let alone, it's delicious.

Seeing Qin Luo's chewing movement, a smile flashed in Ou Yilin's eyes.

"Since you have accepted my gift, then we are friends, do you think that classmate Qin?" Oylin squinted and said.

friend?

A stick of gum?

Is this friend too cheap?

But thinking about the sour taste in his mouth, Qin Luo couldn't say anything.

Is it possible to spit out the gum and return it to her?

Think about it, forget it.

Qin Luo really couldn't do such a compelling thing. At any rate, he was also a university professor and the youngest professor in the history of Yanjing University.

"Of course, we have always been friends." Qin Luoyi said righteously.

Upon hearing Qin Luo's words, a tricky smile flashed in Ou Yiling's eyes.
