After the old man made such a stir, Xiao Yuan and Xia Jiuying completely quieted down, and after returning to the bed and lying down, they no longer dared to play loudly.

"That's not right!" Xiao Yuan suddenly remembered something, sat up straight all of a sudden, and said in surprise.

"What's wrong?" Xia Jiuying also sat up and asked curiously.

"Our room is soundproof, even if the noise we made just now was a little loud, the old man shouldn't have heard it." Xiao Yuan said.

"yes, why?" After being reminded by Xiao Yuanyi, Xia Jiuying also felt a little unbelievable about this question.

"Didn't you say that his martial arts are very strong, much stronger than Master Tong, could it be that this is the reason, don't those martial arts novels say that the master can even hear the mosquito humming a few kilometers away?" Xia Jiuying said.

"Martial arts novels are exaggerated, and martial arts in reality can't be so magical at all." Xiao Yuan said with a smile.

"Not necessarily, what evidence do you have that it can't be without in reality?" Xia Jiuying argued.

"I really can't find any evidence, according to what you say, isn't that old man a jing?" Xiao Yuan said.

"Xiao Yuan, you said that we are talking like this now, will he hear it?" Xia Jiuying asked.

"It shouldn't be possible, we were making a lot of noise just now, but now we can lower our voices and speak, his hearing won't be against the sky to this extent, right?" Xiao Yuan said.

"I hope so." Xia Jiuying said.

"Anyway, we'd better keep it quiet." Xiao Yuan said, and subconsciously looked at the door as he spoke.

"Hear it, hear it, you didn't do anything bad." Xia Jiuying said.

"yes, I don't think I've been scared by that old man." Xiao Yuan laughed, said, and after speaking, he lay back on the bed, opened his arms and said, "Lie down and sleep." ”

Xia Jiuying snuggled into Xiao Yuan's arms, stretched out her hand to hug his waist, and said softly, "Xiao Yuan, have you forgotten something to tell me?" ”

"How could I forget, I met Sister Sa in San Francisco, I won't hide this from you, you have the right to know all the details." Xiao Yuan hugged Xia Jiuying into his arms and said.

"You didn't come back last night, were you with Sister Sa?" Xia Jiuying asked.

"Hmm." Xiao Yuan did not deny it.

"Xiao Yuan, if you didn't come back yesterday, I had a hunch that you might be with Sister Sa, I'm so scared, I'm afraid that you won't come back again, if you don't come back, I don't know what I should do." Xia Jiuying said quietly.

"Silly girl, why don't I come back, I won't have this kind of thought in the future, okay?" Xiao Yuan stroked Xia Jiuying's soft hair, his heart was full of tenderness, and he comforted softly.

"Hmm." Xia Jiuying responded, paused for a moment, and then said, "Xiao Yuan, the matter between you and Sister Sa belongs to the two of you, I don't want to know those details, but I have a request, you must agree to me." ”

"What requirements?" Xiao Yuan asked.

"When you're with me, treat me wholeheartedly, don't think about Sister Sa, okay?" Xia Jiuying said.

"Okay, I promise you." Xiao Yuan was moved in his heart, Xia Jiuying's request was exactly the same as Tang Sa's request at the beginning, if he couldn't even do this request, how could he be qualified to have them.

"Xiao Yuan, let's sleep, it's been a busy day, I'm very sleepy." Xia Jiuying heard Xiao Yuan agree without hesitation, raised his head and kissed him on the face, and said softly.

"Okay, let's sleep." Xiao Yuan kissed Xia Jiuying back, said with a gentle smile on his face.

…………

The next day, when Xiao Yuan was in class, there was an old man with a childish face in the class, but full of momentum, Berkeley's classes were all open, although the students in class were very surprised by the sudden appearance of such an anomaly in the classroom, but he just sat in the classroom and closed his eyes quietly, so naturally he would not drive him out.

The old man didn't take the initiative to give people faces, and the incident that Xiao Yuan was most worried about didn't happen, so he was relieved.

At noon, the old man suddenly became interested in Xiao Yuan's professionalism.

"Boy, you gave the old man another surprise today, the old man originally thought you were a computer major, but I didn't expect you to be a mathematics major, can you tell me why this is the case, was it the wrong choice, or did it happen on purpose?" After lunch, when everyone gathered in the living room of the villa to drink tea, the old man asked.

"It's deliberate." Xiao Yuan replied.

"Can you tell the old man why?" The old man asked curiously.

"Because mathematics is the foundation of all natural sciences, and computer science is no exception, I love computers and networks, so I want to make achievements in this area, so I chose mathematics major." Xiao Yuan replied.

"Is this what you really think, do you study math?" The old man was a little surprised by Xiao Yuan's answer.

"Any questions?" Xiao Yuan asked rhetorically.

"As the saying goes, learn literature and martial arts, sell the emperor's family, although there is no emperor's family now, but the word goods are still the fundamental purpose of the vast majority of students' learning, nothing more than the word utilitarian, but the old man from your words, but did not hear any utilitarianism, so he asked." The old man said.

"Why don't you say I'm not utilitarian, actually." Xiao Yuan said.

"Why do you say that?" The old man asked with interest.

"The so-called utilitarianism, directly said to be to obtain benefits for the purpose of driving all their own behavior, I think the reason why you say that I have no utilitarianism, is because I chose mathematics for the purpose of improving my computer technology, and did not mention any interests, but you don't forget, if any technology can be done to the extreme, the so-called interests, money, or fame, are just add-ons, really coming, can't stop it." Xiao Yuan said.

"I think your computer skills are already very good, even Xiaojie's girl listens to you in many ways, this alone is amazing, do you have a higher goal?" The old man asked.

"Maybe, I don't think the goal is important, the important thing is that I like it, so I'm willing to pay for it and improve my knowledge system." Xiao Yuan said.

"It seems that the old man still underestimates you, you are worthy of a young man with a thirty-year-old soul, his ideas are different from ordinary people, and the old man studies physiognomy for the sake of easy learning." The old man sighed.

"Grandpa, I'm afraid you don't know, my brother also has a deep study of what you said about Yi Xue, of course, he studied Yi Xue, also for his computer." Lin Ran interjected on the side.

"Xiao Ran, don't talk nonsense, how can the little fur I studied be compared to the old gentleman." Xiao Yuan said with a smile.

"You still study easy learning?" The old man's eyes lit up, and he asked in surprise, "The old man is very curious, how can Yi Xue, such an ancient science, still have a connection with computers, what do you want to use Yi Xue for?" ”
