Chapter 97: You want to fight back? Can you beat me? After accompanying Song Yao to the gate of the community, when Xu Qingzhou returned home, Mr. Xu and Ms. Wang were watching TV. Wang Xiaping was a little surprised, "Hey, why are you back so early?" "It's already 9 o'clock." Xu Qingzhou took a big apple from the cupboard without washing it, took a bite, and sat down on the sofa. "Isn't it dirty? You don't even know how to wash it!" Wang Xiaping stared with her eyes wide open. After only four days, she began to feel visual fatigue and nothing pleased her. "It's not clean, but you won't get sick if you eat it." Xu Qingzhou said lazily. Wang Xiaping wanted to complain about how he didn't sit properly, but seeing Xu Qingzhou's nonchalant look, she gave up and asked, "Were you with Xiaoyao just now?" "Yes, I just sent her back to the community."
Day 5. Xu Qingzhou is using the f(p) function to prove that q - p≤ C× log p. Even though the upper bound has been relaxed to C×(log p)^α, it is still difficult to make progress. No specific values, just put it simply: Although f(p) gives a certain measure of the "density" of prime numbers less than p, and the expression for p is also perfect, when q is the smallest prime number greater than p, qp≤f(p), but now we can only prove that f(p) may be related to a certain power of logp. After staying at home for an afternoon, Xu Qingzhou was awakened by his protesting stomach. He put down his pen and came out of the room. He saw his father watching a football game in the living room and couldn't help asking, "Dad, where is my mom?" "Playing mahjong." Xu Shouyun said without turning his head. Xu Qingzhou: "It's already 4: and you're still playing mahjong?" Xu Shouyun glanced at the clock next to him, also a little surprised, and said, "It's already this late? Call your mother to come back." Xu Qingzhou was speechless and shook his head. He walked to the refrigerator, only to find that there was no food left. He had no chance to cook, so he simply stood in front of the window, breathing in the fresh air, and called his mother at the same time. When the call was connected, the sound of mahjong tiles colliding could be heard from the headset. "Son, what's the matter?" "Mom, it's 4:." Xu Qingzhou reminded. "Oh, it's 4: already? Come back right away!" Xu Qingzhou: “.” After the call, he sat down to watch the game with his dad. "You do that thing." During the break in the game, Xu Shouyun finally had time to care about his son. He stroked the thermos cup with his hand and said, "Don't push yourself too hard." "I know." Xu Qingzhou nodded. "It's enough to have an idea. Your mother and I don't expect you to achieve much in the future." The conversation ended quickly because the game started soon. Half an hour later, Wang Xiaping came in with some food. She looked at the two people eating for free in the living room and said with a sour face, "You two, father and son, will starve to death without me."
Xu Qingzhou and Lao Xu looked at each other and immediately realized that Ms. Wang had probably lost money. Moreover, judging from the situation, the lost assets might have reached a huge sum of more than ten yuan. My mother is like this. Even if she wins two or three dollars, she will spend twenty dollars to buy half a chicken to satisfy her hunger. "Xu Qingzhou, stop looking and come over here to peel the garlic!" "Here they are." Xu Qingzhou stood up and walked over. As expected, he found that his shopping bag was full of vegetarian dishes such as eggplant and cucumber. "No meat?" "You eat meat every day, but can't you survive without it for a day?" After dinner, Xu Qingzhou received a call from Wang Wei, saying that the second phase had officially ended and Professor Zhao was trying to get the MRI equipment from the Second Hospital. If all went well, they could enter the experimental phase when school started. Finally, Wang Wei asked for Xu Qingzhou's bank card number to receive the bonus at the end of the second stage. In the following time, Xu Qingzhou went out and bought 8 Shuangliu Lao Ma Rabbit Heads from a nearby store, one of which was for Song Yao's roommate. On the 7th day of the National Day holiday, at 9 o'clock in the morning, Xu Qingzhou had a hearty breakfast and prepared to leave. Seeing Xu Qingzhou packing up, Wang Xiaping began to sigh again, feeling that time passed too quickly and in the blink of an eye her son would have to go to school again. "Dad, Mom, I'm leaving." Xu Qingzhou, carrying a mountaineering bag, waved to the two people at the gate of the community, and went to meet Song Yao and others at the gate of Chengnan Middle School. The four of them were in different locations, so if their parents were to send them, they would have to run around to pick them up. After thinking it over, they decided to just take a taxi. Guo Ziyang arrived first, followed by Xu Qingzhou. The two stood at the school gate and looked at the eye-catching sign that read "Idle people in society are prohibited from entering the campus" at the gate, feeling a sense of emotion. Sure enough, the promise of welcoming you back often is no longer true. About 5 minutes later, Song Yao arrived. At this moment, she was completely different from what she was three days ago. She was wearing a beige T-shirt, high-waisted wide-leg jeans, and had a cold expression. Her aura could be felt even from dozens of meters away. It was so shocking that Xu Qingzhou started to wonder if the weak and fragile girl he saw two days ago was Song Yao. Seeing Xu Qingzhou staring at her, Song Yao raised her eyebrows and asked, "Is there something on my face?" "The eye booger is still there." Xu Qingzhou said. Song Yao's face froze, she turned around silently, took out a small mirror, and saw nothing but a beautiful face. She immediately realized that she had been deceived. "Hiss~ Why are you pinching me again!" "Why are you glaring at me? Do you want to fight back? Can you beat me?!" Guo Ziyang retreated to the side unnoticeably, leaving space for the two flirting people next to him. He also wondered where Xu Qingzhou learned the technique of picking up girls, and just a few words made the cold and aloof school beauty Song break down. A few minutes later, Ding Jiahui came in a hurry, with the suitcase being dragged around. Guo Ziyang came forward from 10 meters away and took the suitcase. Xu Qingzhou looked strange, and whispered to Song Yao: "Are you sure Ding Jiahui doesn't know that Guo Ziyang likes her?" Song Yao nodded her chin slightly. She had hinted at this, but Ding Jiahui didn't notice Guo Ziyang's little thoughts at all. She complained in her heart, "Jiahui, Jiahui, with your observation ability, you still want to ship CP and be a love consultant." The four of them met up, and Xu Qingzhou's taxi also arrived. They took the car directly to the airport and boarded a flight to Kyoto.
The weather in Kyoto was gloomy, completely different from that in Chengdu. There was a slight chill in the breeze and there were tidal pools on the ground, apparently it had just rained. At 4 ., Xu Qingzhou and Song Yao appeared on the Peking University campus. They ate at the Farm Canteen and then sent Song Yao back to the dormitory. 206 Dormitory. Song Yao opened the door and found that there was no one in the dormitory. Zhang Qiong, Teng Xiaojuan and the others had gone to eat. She put down her things and walked to the balcony. People were coming and going downstairs, but there was no one she wanted to see, so she breathed a sigh of relief. Looking at the empty dormitory, she inexplicably felt lonely and wanted to cry. Taking a deep breath, Song Yao suppressed the sadness, opened the suitcase and took out the things. She first took out a pile of books. These were professional books and materials. After entering university, the people around her suddenly became outstanding, and she now felt the pressure. In particular, Xu Qingzhou is even better than he was in high school. So this time when she went back, she brought a lot of books with her to strengthen her professional knowledge and keep up with Xu Qingzhou's pace. (End of this chapter)
