I almost touched the moon

When Cheng Xuan returned home at night, he found Cheng Che at home. He asked in surprise, "Brother, aren't you with Iseylia?"

When Cheng Che heard his name, he subconsciously frowned and glared at him, "Did you call me Iseylia too?"

"What's wrong?" Cheng Xuan disagreed. "Everyone calls her that. She also said that we don't need to call her professor. We can just call her Iseylia."

Cheng Che frowned even more after hearing this. Although his tone was unhappy, he was somewhat proud. He glanced at Cheng Xuan and said, "Then is she someone else's sister-in-law?"

"I wish she was someone else's sister-in-law..."

Cheng Xuan curled his lips and complained in his heart, "Oh my God, who can understand my suffering? I will have to endure mixed doubles every day from now on. Who can be as unlucky as me!!!"

Cheng Che listened to his words, but he didn't seem to take them to heart. He continued flipping through the book in his hand and spoke very nonchalantly, "She must be my wife. If you don't want her to be your sister-in-law, I don't mind changing her to a younger brother."

He even smiled at Cheng Xuan, which made him shudder.

"Cheng Che!!!" Cheng Xuan protested, feeling very aggrieved for himself, "Cheng Che, I am your biological brother!! I am your only biological brother!!"

"Not necessarily." Cheng Che continued to read the book, his eyes smiling. His smile was as gentle as it could be, but his words were as ruthless as they could be. "Maybe Mr. Cheng has illegitimate children that we don't know about. So, she is definitely my only wife, but you are not necessarily my only brother."

"Cheng Che, you're really too cruel." Cheng Xuan sprayed out the water he had drunk. "It's enough that you dissed me, but why did you also make up stories about our father? I finally understand what it means to be crazy about love and not recognize any relatives."

Cheng Che didn't get angry after hearing what he said. He still smiled faintly and flipped through the book in his hand.

Cheng Xuan took a look and found that it was the December issue of the Journal of Astronomy and Astrophysics last year. He didn't know when his good brother became interested in astrophysics. He felt a headache after reading the literature published in this magazine.

"It's good that she's my sister-in-law..." Cheng Xuan thought for a long time and finally thought of a good thing, "If you can help me blow her pillow wind, maybe she will go easy on me, and I can pass the thesis and exam this time."

"Impossible." Cheng Che seemed to have finished reading the literature, put down the magazine and looked at him, "Don't you know Iseylia? She is absolutely rigorous and fair in academics. If you ask me to persuade you, then I won't even be able to be by her side."

After saying that, he glanced at Cheng Xuan, who was lying on the sofa playing Switch, and said with some regret: "Can you go study? When Song Song was studying for his master's degree, he never went to bed before 3 a.m. from Monday to Friday. Look at you, you go back to your room at 10 a.m. every day and fall asleep at 12 a.m."

"It doesn't matter." Cheng Xuan said while playing games, "I don't need to do any academic research, as long as I can pass the exam and graduate. Besides, it's vacation now, why should I study?"

"Do you think you can graduate?" Cheng Che asked back unhappily.

Then he handed the magazine to Cheng Xuan and said, "The first article on the front page is Iseylia's paper. Take a look and learn from it."

"I won't read it." Cheng Xuan completely ignored the magazine that Cheng Che handed over and continued playing games. "I can't understand her paper."

"Cheng Xuan!" Cheng Che suddenly got angry and said in a reproachful tone, "You always say that she is too strict and that she is targeting you. How could she be so free to target you? Look at your attitude towards studying. If I were her, I would fail you too."

"Brother, you are really a traitor." Cheng Xuan pouted and said, "She is not targeting me. She despises everyone who can't get 2 equally."

Cheng Che immediately said, "She is not that kind of person. She is just very rigorous. With your personality and poor attitude towards study, you shouldn't have studied astrophysics in the first place. Astrophysics is a subject that requires the most rigorous and rational thinking."

Cheng Xuan put down the game console, looked at Cheng Che and smiled, half-jokingly saying: "Brother, I am a graduate student after all. Why are you, an undergraduate, teaching me how to study?"

"Really?" Cheng Che smiled with an indistinct meaning. "But I graduated from the Swiss Federal Institute of Technology in Zurich, which is ranked seventh in the world, and I never failed a course or had my graduation delayed. Which university did you go to for your undergraduate degree?"

"Our school...although not as good as ETH, it is at least a 985 university, okay?" Cheng Xuan said proudly, "My undergraduate average score is also above 85 points, which is between 2.0 and 1.7 when converted into German scores, which is pretty good."

"Oh, I see. What's your world ranking? Are you in the top 100?"

Cheng Che never liked to talk about rankings, and rarely mentioned that he graduated from the Swiss Federal Institute of Technology. But seeing Cheng Xuan showing off a bit, and thinking of what Wen Song had said to him, he also wanted him to face reality and not be blindly confident in himself.

Cheng Xuan continued to be stubborn and said, "Brother, according to what you said, LMU's world ranking is not as good as ETH, but Iseylia is an undergraduate and master's student of LMU. Do you look down on my sister-in-law's alma mater?"

"I don't have any." Cheng Che explained immediately, "Iseylia always ranked first in her major during her graduate studies. Her undergraduate average score was 1.35 and her graduate average score was 1.14. Look at you. You spent yuan on the agency fee just to apply to LMU."

"Oh, so what? I'm not competing with her. But the fact is, my dear brother, I'm a graduate student and you're an undergraduate."

Cheng Xuan still didn't realize his own problem, and continued to happily defend himself, and even made a face at Cheng Che, "Undergraduates should not interfere in the affairs of us graduate students."

Cheng Che was both angry and amused after hearing what he said. He walked up to Cheng Xuan, touched his head and said, "You make sense, Xuan. Although I am an undergraduate and don't understand your graduate courses, and I can't persuade Professor Iseylia for you, if I tell her that you used ChatGPT when writing your paper, I think she would be happy to know about it and give you a very fair score."

Cheng Xuan ignored his threats and said confidently, "It's impossible. She won't believe it. Even if you said so, it doesn't matter. She can't tell the difference without evidence."

"Really?" Cheng Che really admired his brother's confidence and immediately called Wen Song.

When Cheng Xuan saw him calling, he immediately panicked and began to beg for mercy, "Brother, I was just joking, please don't call her. My sister-in-law is busy with all kinds of things, please don't disturb her."

However, before he could finish his words, the phone was connected. Wen Song's voice on the other end of the phone was still as cold as usual, but a little gentler than usual. "What's the matter?"

Cheng Che smiled very touchingly and asked gently, "Baby, what are you doing?"

When Cheng Xuan heard the word "baby", he felt goosebumps all over his body and he vomited subconsciously. He could not associate Wen Song, a serious and somewhat harsh person, with the word "baby".

"I'm revising my paper." Wen Song's voice was obviously a little tired, and he yawned. "I can't finish revising it. It's so annoying."

Cheng Che also laughed after hearing this. When Wen Song was a student, he stayed up late every day to finish his thesis. He never thought that after becoming a professor, he would still have to stay up late to revise his thesis.

He smiled and said, "You've worked so hard, honey. Have you revised Cheng Xuan's paper?"

"I'm revising it." Wen Song sighed, a little speechless, "It would be fine if you didn't ask me, but I get angry when you ask me. What did he learn in undergraduate studies? He even got the basic theory wrong. When calculating the data, I emphasized many times that approximate values ​​cannot be taken. As a result, he rounded off here and estimated there, and the final calculation result was a world away from the correct result..."

After hearing this, Cheng Che glanced at Cheng Xuan's almost crying expression and laughed even more happily. Seeing that Wen Song was really speechless, he quickly coaxed her, "Thank you for your hard work, my baby. I'll help you scold him. He is just like that, not serious at all."

Cheng Xuan quickly mouthed, "Brother!!! Please, say something good for me." After saying that, he looked at Cheng Che with a pleading look on his face.

"And his English, I can't understand what he's writing at all. He should have received bilingual education, right? Why is his English so bad? His spoken English is OK, but his handwriting is really a mess."

Wen Song sighed again, "I tried to translate what he wrote into Chinese, but I don't know if it's because my Chinese is too poor, I couldn't understand it even more."

Cheng Che almost had a stomachache from laughing, and said to Wen Song, "It's just that his English is too bad. How can it be your fault? My baby speaks Chinese very well."

"Fine..." Wen Song sighed again, "If you have time, help him with his English. At least his writing should be understandable. My head really hurts."

"Okay~ I get it~" Cheng Che and Wen Song spoke in such a gentle tone that Cheng Xuan couldn't help but wonder if the person in front of him was really his somewhat cold-blooded elder brother.

"Baby, I will definitely give him some tutoring and help him make up for it. Honey, have you eaten yet?"

"Not yet." Wen Song yawned again, "I don't know what to eat."

"Why aren't you eating again?" Cheng Che frowned slightly and asked cautiously, "How about I come to your house and make you something to eat?"

"Okay."

Wen Song agreed immediately, and suddenly thought of something, and said to Cheng Che: "There is one more thing. When I was correcting Cheng Xuan's paper, I found that there was a problem with his analysis format. It's not that the format is wrong, but it is very similar to the answer given by ChatGPT. But I have no evidence, so I can only give him the benefit of the doubt."

When Cheng Xuan heard this, he was so scared that he broke out in a cold sweat. He kept winking at Cheng Che and whispered, "Brother!! Please keep this a secret for me!! Please! You are my most beloved big brother, you are my real brother!"

Cheng Che glanced at him, somewhat dissatisfied, but in the end he did not say anything to Wen Song. He just said, "I don't know. I wasn't there when he was writing the paper."

"It's okay. I'm not asking you." Wen Song said calmly, "But if you have time, please remind him that he must not use any answers from generative AI. If he does, it will be academic plagiarism and I will give him 0 points directly."

"Got it, baby." Cheng Che glared at Cheng Xuan fiercely, but he didn't "kill his own relatives for the sake of justice". He just said to Wen Song, "I will definitely teach him a lesson. The brat is so careless. I will help you beat him up. Baby, I'm coming to your house now. What do you want to eat?"

"Didn't you say chicken wings stew?" Wen Song smiled, "I'll continue to revise my paper. See you later."

Cheng Xuan was even more surprised after hearing this. He never thought that Cheng Che could actually cook, and even went to Iseylia's house late at night to cook for her.

Subconsciously asked: "Brother, can you cook?"

Cheng Che nodded: "Yes."

Cheng Xuan snorted and said, "Then why don't you cook for me."

Cheng Che laughed twice after hearing this and said jokingly, "You are not my wife, why should I cook for you?"

After hanging up the phone, Cheng Xuan heaved a sigh of relief, walked up to Cheng Che and hugged him tightly, almost crying, "Brother!! Thank you! You are indeed my brother!! I really didn't use ChatGPT's answer, I just took it as a reference..."

Cheng Che didn't bother to pay attention to his explanation and glared at him, "It's useless to talk to me. I'm not your professor."

After hearing what he said, Cheng Xuan very tactfully picked up the magazine and said, "I'll go study now. I'll read Professor Iseylia's paper. I'll study hard. Please don't tell her."

Cheng Che looked at his back as he ran upstairs quickly, and shook his head helplessly. He suddenly thought of what Wen Song had joked with him, "I have to make them suffer the same hardships that I have suffered," and thought of Cheng Xuan complaining about his hardships every day, and suddenly laughed.

It seems that everything is still the same as five years ago and nothing has changed.
