Chapter 97 Want to fight back? Can you beat me?
Accompanying Song Yao to the gate of the community, when Xu Qingzhou returned home, Lao 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 cabinet without washing it. He took a bite and sat down on the sofa.
"Isn't it dirty? I don't even know how to wash it!"
Wang Xiaping stared. It had only been 4 days, but she had already begun to suffer from visual fatigue, and nothing she saw was pleasing to the eye.
"It's not clean. You won't get sick after eating it." Xu Qingzhou said lazily.
Wang Xiaping wanted to say whether she was sitting or not, but Xu Qingzhou gave up and asked, "Are 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×logp. Even if the upper bound has been relaxed to C×(logp)^α, it is still difficult to advance.
Without specific numerical values, simply put:
Although f(p) gives a certain measure of the "density" of prime numbers less than p, the expression of p is also very complete. When q is the smallest prime number greater than p, There is 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 all afternoon, Xu Qingzhou was woken up by his protesting stomach. He put down his pen and came out of the room. He saw his father watching the football game in the living room and couldn't help but ask: "Dad, where is my mother?"
"We're playing mahjong." Xu Shouyun said without looking back.
Xu Qingzhou: "It's already 4:30 and you're still playing mahjong?"
Xu Shouyun glanced at the wall clock next to him, and was a little surprised, and said, "Is it already this hour? I called your mother to come back."
Xu Qingzhou was speechless and shook his head. He walked to the refrigerator and found that there was no food in the refrigerator. He had no chance to cook. He simply stood in front of the window, sucked in the fresh air, and dialed his mother's phone at the same time.
When the call was connected, the sound of mahjong collision came from the headset.
"Son, what's the matter?"
"Mom, it's 4:30." Xu Qingzhou reminded.
"Ah, it's 4:30 already? Be right back!"
Xu Qingzhou: "."
After making the call, he sat down and watched the football game with his father.
"You do that thing." Between games, Xu Shouyun finally had time to care about his son, rubbing his hand on the thermos cup, "Don't push yourself too hard."
"I know it." Xu Qingzhou nodded.
"Just know it. Your mother and I don't expect you to have much success in the future."
The conversation ended quickly because the game soon started.
Half an hour later, Wang Xiaping came in with vegetables. She looked at the two people eating in the living room and said with a bad face: "You two, father and son, will starve to death without me."
Xu Qingzhou and Lao Xu looked at each other and immediately understood that Ms. Wang had probably lost money. Moreover, looking at this situation, the lost assets might have reached more than ten yuan.
My mother is like this. Even if she wins two or three yuan, she can still spend twenty yuan to buy half a chicken and bring it back for the tooth ceremony.
"Xu Qingzhou, stop looking and come over and peel the garlic!"
"Here we come." Xu Qingzhou stood up and went over. Sure enough, he found that his grocery shopping pocket was full of vegetarian vegetables like eggplants and melons.
"No meat?"
"You eat meat every day, and you can't live without it for a day?" After dinner, Xu Qingzhou received a call from Wang Wei, saying that the second phase was officially over. Professor Zhao was grabbing the MRI equipment from the second hospital. If everything goes well, school would start. You can enter the experimental stage.
At the end, Wang Wei asked for Xu Qingzhou's bank card number to receive the bonus at the end of the second phase.
The next time, Xu Qingzhou went out and bought 8 Shuangliu Mom Rabbit Heads from a nearby store, one for Song Yao's roommate.
On the seventh day of the National Day holiday, at 9 o'clock in the morning, Xu Qingzhou had a hearty breakfast and was ready to leave.
Seeing Xu Qingzhou packing things, Wang Xiaping began to sigh again, lamenting that time passed so fast, and her son had to go to school again in the blink of an eye.
"Dad, Mom, I'm leaving."
Xu Qingzhou carried a hiking bag, waved to the two people at the gate of the community, and went to meet Song Yao and the others at the gate of Chengnan Middle School.
The four of them were in different directions. If their parents dropped them off, they would have to run around to pick them up. After thinking about it, I decided to take a taxi there myself.
Guo Ziyang arrived first, followed by Xu Qingzhou. The two of them stood at the school gate, looking at the eye-catching "Idle persons are not allowed to enter the campus" sign posted at the door, and felt a sigh of relief.
Sure enough, the vow to welcome back often was no longer there after all.
About 5 minutes later, Song Yao arrived.
At this time, she was completely different from three days ago. She was wearing a beige T-shirt and high-waisted wide-leg jeans. She had a cold expression, and she could feel the cold aura from dozens of meters away.
So much so that Xu Qingzhou was a little bit tongue-tied, wondering if the soft and frail girl he saw two days ago was Song Yao.
Seeing Xu Qingzhou staring at her, Song Yao raised her eyebrows and asked, "Is there a flower on my face?"
"The eye poop is still there." Xu Qingzhou said.
Song Yao's face froze, she turned around silently and took out a small mirror. There was nothing but a beautiful face, and she immediately understood that she had been deceived.
"Hey~ why are you pinching someone again!"
"Why are you staring? Do you want to fight back? Can you beat me?"
Guo Ziyang retreated to the side without leaving a trace, leaving space for the two flirting people next to him. He also lamented where Xu Qingzhou learned the technique of flirting with girls. With just a few words, the cold school beauty of Song Dynasty broke through.
A few minutes later, Ding Jiahui came in a hurry, and the suitcase was dragged around.
Guo Ziyang came up to him from 10 meters away and took the suitcase.
Xu Qingzhou looked strange and spoke to Song Yao in a low voice: "Are you sure Ding Jiahui doesn't know that Guo Ziyang likes her?"
Song Yao's chin nodded slightly. She had deliberately made an insinuation. Ding Jiahui didn't notice Guo Ziyang's little thoughts at all, and complained a little in her heart, Jiahui, Jiahui, with your little observation skills, you still want to take CP, and you still want to be Love Counselor
The four of them met, and Xu Qingzhou’s taxi also arrived. They took the car directly to the airport and boarded a plane flying to Kyoto.
The weather in Kyoto is gloomy, which is completely different from that in Chengdu. There is a hint of coolness in the breeze, and there are still water stains on the ground. It seems that it has just rained.
At 4 o'clock in the afternoon, Xu Qingzhou and Song Yao appeared on the Peking University campus, went to the farm cafeteria to eat, and then sent Song Yao back to her dormitory.
Dormitory 206.
Song Yao opened the door and found that no one was in the dormitory. Zhang Qiong and Teng Xiaojuan had all 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 let out a breath.
Looking at the empty dormitory, she felt an inexplicable feeling of loneliness and wanted to cry.
Taking a deep breath, Song Yao suppressed the sadness, opened the suitcase and took out the things.
First, she took out a lot of books. These were all professional books and materials. After entering college, the people around her suddenly became outstanding, and she now felt pressure.
In particular, Xu Qingzhou is simply better than he was in high school.
So she brought a lot of books when she went back this time to strengthen her professional knowledge and keep up with Xu Qingzhou's pace.
