Chapter 95 Do you have money to buy fish for my dad? Xu Qingzhou had just put the things on the table when Wang Xiaping pushed the door open and came in, holding a plate in one hand with washed grapes and chopped apples on it. Putting down the fruit plate, he glanced at the complicated symbols on Xu Qingzhou's manuscript paper and marveled inwardly, "Don't stay up too late, go to bed early." "I'll read some information and then go to sleep." Xu Qingzhou nodded. "What time is it? Are you still reading materials? Don't take advantage of your youth and ignore your health. I know you have been staying up late for the past month." "Song Yao told you that, right?" "Who cares who said that? An expert said that staying up late is a form of chronic suicide!" "Qingzhou, I support your mother in this matter." Xu Shouyun walked in at this time, "Studying is important, but health is the capital. If your body is broken, let alone the scholarship, even if you win some world award, your mother and I will not be happy." "That's right, at such a young age, there aren't that many things to worry about and stay up late every day." Xu Qingzhou was touched and couldn't help but think of his past self, who died in an accident, leaving behind his elderly parents. He took a deep breath and assured with a smile: "Dad, Mom, don't worry, I will definitely ensure my health in the future." After a pause, he continued, "Besides, now that Song Yao is watching over me, I go running twice a week."
Sure enough, upon hearing that Song Yao was watching, Wang Xiaping and Xu Shouyun felt much more relieved. They asked Xu Qingzhou to go to bed early, left the room without disturbing him anymore. The door closed, the TV in the living room was turned off, and the sound disappeared. Since Xu Qingzhou had slept for more than an hour on the plane that night, he was not really sleepy now and planned to write for a while. As the sound of the TV disappeared, the surrounding environment became even quieter, with the rustling sound of the pen tip rubbing against paper and the low buzzing of insects coming from outside the window. In the master bedroom, Wang Xiaping couldn't sleep the more she thought about it. She pushed Xu Shouyun beside her and asked, "Did you see the things on his desk just now?" "Yeah, I took a peek." "There are circles, squares, and all kinds of strange symbols. At first glance, they really look like that," said Wang Xiaping. Xu Shouyun smiled softly, "You said that as if a child was joking. I was serious. There are mathematical formulas on it." "You've got it?" “I just couldn’t understand it until I realized it was a mathematical formula.” In the bedroom, there were two people talking in low voices. Next door, Xu Qingzhou wrote for a while, then tidied himself up and lay down on the bed to rest. The sheets and quilt covers had just been changed by Wang Xiaping, and they still had a faint scent of laundry detergent. He let out a long breath, closed his eyes, and his consciousness quickly fell into chaos. For Xu Qingzhou, the first three days of the National Day holiday passed quickly. On October 10, Ms. Wang, the chairman of the Xu family, got up early and made a very sumptuous breakfast. On October 10, breakfast was slightly worse than the first day, but still good. On October 10, the job of washing dishes fell on Xu Qingzhou's shoulders. At 3 o'clock in the afternoon, Xu Shouyun went fishing with his fishing rod, while Wang Xiaping was watching TV in the living room. Xu Qingzhou came out of the bedroom, took a cup to get some water, and saw the seasoning package on the table, "Did you just buy the fish hot pot seasoning?"
"Well, your dad went fishing. Let's have fish tonight," said Wang Xiaping. Xu Qingzhou smacked his lips and flipped through the condiments. He was actually a little greedy. He had made it himself before, but it was never as delicious as the one at home. After a pause, he thought of something more important and asked, "You didn't forget to give my dad the money to buy fish, did you?" In front of the fish pond. "A-choo~" Xu Shouyun sneezed. Could it be that my family is missing me? A middle-aged man wearing a sun hat came over and asked with a smile, "Lao Xu, how was the harvest?" Xu Shouyun glanced at the clear bucket and replied calmly: "Soon." "Just now, there was a young man who was very good at fishing. He caught a silver carp weighing more than ten kilograms." The middle-aged man put the empty bucket on the ground and set up the pole next to Xu Shouyun. "Haha, it's just the novice protection period." "that is!" Wutong Community. Looking at Xu Qingzhou, who was laughing and looking tired, Wang Xiaping was a little disgusted, "Look at you, you don't even know how to go out for a walk during the holidays, and you stay at home all day." "Mom, it's only the third day." Xu Qingzhou sat lazily on the sofa. "Only the third day?" Wang Xiaping took out her cell phone and found that it was only October 3rd, which means there were still four days left. She couldn't help but sigh inwardly why the National Day holiday was so long. Xu Qingzhou shook his head, rested enough, took the cup of water into the bedroom, and continued to work hard. Wang Xiaping's voice came from behind him: "Remember to open the window for ventilation!" "It's open." During these three days, Xu Qingzhou went out only once - to buy manuscript paper because the amount of calculations was too huge. Now, he has devised a more complex function based on the properties of the zeta function, which he has named f(p). It is very difficult to directly prove a constant C such that for all sufficiently large prime numbers p, its successor prime number q (that is, the smallest prime number greater than p) satisfies q - p ≤ C × log p. So he wanted to use this function to gradually approximate and relax the upper bound to C×(log p)^α, where α is a real number greater than 1 but less than 2. He first tried to prove that this was true and then expanded the result to a larger range. Although the difficulty was reduced by imposing conditional restrictions, progress was still slow. It took two days just to set the f(p) function. I don’t know if they were disliked by their parents, but from the third day on, this group of newly returned college students began to plan a class reunion in the group. Zhang Yuquan was particularly active and took the initiative to act as the organizer of the event. Guo Ziyang and Ding Jiahui both wanted to go; the class reunion was very attractive to them. Xu Qingzhou simply went along as well, just to go out and relax, and Song Yao naturally came along as well. December 10, 4pm. Xu Qingzhou dressed up and, thinking that he was going to have hotpot in the evening, he chose a black T-shirt and went out. As agreed, they gathered at the gate of Chengnan Middle School. The temperature in Chengdu is much higher than in Kyoto, but Song Yao still wore the gray coat she bought last time. Seeing that Xu Qingzhou was not wearing the T-shirt she bought, Song Yao felt a little disappointed.
"We are having hot pot tonight, right?" Seeing that Ding Jiahui and Guo Ziyang were both wearing white clothes, Xu Qingzhou even wondered if he had remembered it wrong. "correct." "Then you still wear white clothes." "It looks good." Ding Jiahui never wastes her energy on herself, but only questions others, "Look at you, you don't even know how to clean up." When the four of us arrived, there were more than 10 people in the private room and it was very lively. Xu Qingzhou immediately spotted Zhang Yuquan standing in front of the crowd. He looked very proud and was chatting happily with his classmates. He seemed more confident than he was in high school. (End of this chapter)
