Chapter 95: You don't have the money to buy fish for my dad

Xu Qingzhou just put things on the table, Wang Xiaping pushed the door in, holding a plate in one hand, which contained washed grapes and cut apples.

Putting down the fruit plate, she looked at the complex symbols on Xu Qingzhou's draft paper and was amazed, "Don't stay up too late, go to bed early."

"I'll sleep after reading the materials." Xu Qingzhou nodded.

"What time is it, still reading materials? Don't take your body seriously just because you are still young. I know, you didn't stay up less this month."

"Song Yao told you, right?"

"Don't care who told you! There are experts who said that staying up late is chronic suicide!"

"Qingzhou, I support your mom on this matter." Xu Shou walked in at this time, "Learning is important, but the body is the capital. If the body collapses, let alone scholarships, even if you win any world awards, your mom and I won't be happy."

"That is, so young, there are not so many things to worry about, staying up late every day."

October 4, 4:00 PM.

At 3:00 PM, Xu Shou took the fishing rod to fish, and Wang Xiaping was watching TV in the living room.

For Xu Qingzhou, the first 3 days of the October holiday passed quickly.

"Only the 3rd day?" Wang Xiaping took out her phone and found that it was only October 3rd, which means there are 4 more days, and she couldn't help but secretly sigh at how long the National Day holiday is.

The temperature in Rongcheng is much higher than in Kyoto, but Song Yao is still wearing the gray coat bought last time. Seeing that Xu Qingzhou is not wearing the t-shirt she bought, Song Yao is slightly disappointed in her heart.

"Well, your dad went fishing, so eat fish tonight." Wang Xiaping said.

October 2, breakfast is slightly worse than the first day, but still good.

In front of the fish pond.

"Mom, this is only the 3rd day." Xu Qingzhou sat lazily on the sofa.

Xu Shou smiled gently, "You say this as if the child is playing. It is serious, and there are mathematical formulas on it."

Xu Qingzhou shook his head, rested enough, took the water cup into the bedroom, and continued to struggle. Behind him came Wang Xiaping's voice: "Remember to open the window to ventilate!"

Currently, he has designed a more complex function based on the properties of the z-function, named f(p).

In the bedroom, there is the sound of two people talking in a low voice.

Xu Qingzhou came out of the bedroom, holding a cup to fetch water, and saw the seasoning bag on the table, "Just bought fish hot pot seasoning?"

Xu Qingzhou was touched, and couldn't help thinking of his former self. He left like this when something happened, leaving behind his aging parents... He took a deep breath

"Exactly!"

"It's precisely because I can't understand it that I know it's a mathematical formula."

"Heh, it's just the beginner's protection period."

Exhaling a long breath, he closed his eyes, and his consciousness quickly sank into chaos.

Therefore, he wanted to use this function to gradually approximate, relaxing the upper bound to c×(logp)^a, where a is a real number greater than 1 but less than 2, first proving that this attempt holds, and then extending the result to a larger range.

Looking at the exhausted Xu Qingzhou, who was laughing it off, Wang Xiaping said with some disdain, "Look at you, you're on break and don't even know how to go out for a walk, just staying at home all day."

A middle-aged man wearing a sun hat walked over and asked with a smile, "Old Xu, how's the harvest?"

Xu Qingzhou clicked his tongue and flipped through the seasonings; he was actually a bit tempted. He had made it himself before, but it just didn't taste as good as the home-cooked version.

"Yeah, caught a glimpse."

After a pause, he thought of something more important and asked, "You didn't forget to buy the money for my dad's fish, did you?"

"You understood it?" Sure enough, hearing that Song Yao was watching, Wang Xiaping and Xu Shouyun were immediately much more at ease. They told Xu Qingzhou to go to sleep early and didn't disturb him again, exiting the room.

"We're having hot pot tonight, right?"

Xu Qingzhou tidied himself up, and thinking about the hot pot for dinner, he specifically chose a black T-shirt and headed out, gathering at the entrance of Chengnan Middle School as agreed.

Zhang Yuquan, that guy, was particularly active and took the initiative to become the organizer of the event.

Seeing that Ding Jiahui and Guo Ziyang were both wearing white clothes, Xu Qingzhou even doubted if he had remembered wrong.

Perhaps because they were all being looked down upon by their parents, starting from the third day, this group of college students who had just returned began planning a class reunion in their group chat.

During these three days, Xu Qingzhou only went out once—to buy manuscript paper, as the amount of calculation was too large.

Although he set conditions to limit the difficulty, progress remained slow; just setting the f(p) function took two days.

"Achoo~" Xu Shouyun sneezed. Could it be that someone at home is thinking of me?

Wutong Residential Complex.

"It's on."

Directly proving a certain constant c such that for all sufficiently large prime numbers p, their successor prime q (the smallest prime greater than p) satisfies q-p≤c×logp, is extremely difficult.

After a pause, he added, "Besides, now that Song Yao is keeping an eye on me, I go running twice a week."

"That's right."

Xu Qingzhou simply went along with them, treating it as going out to relax; Song Yao naturally went along too.

Xu Shouyun glanced at the clear bucket and replied flatly with two words: "Almost there."

Next door, Xu Qingzhou wrote for a while, then tidied up and lay on the bed to rest. The sheets and duvet cover had just been changed by Wang Xiaping and still carried a faint scent of laundry detergent.

!.

On October 1st, the chairwoman of the Xu family, Ms. Wang, got up early and made breakfast, which was very sumptuous.

In the master bedroom, the more Wang Xiaping thought about it, the less she could sleep, so she nudged Xu Shouyun beside her, "Did you see those things on his desk earlier?"

Guo Ziyang and Ding Jiahui both wanted to go; a class reunion was very attractive to all of them.

"Just now, a young guy was so good, he caught a white carp weighing over ten jin." The middle-aged man put his empty bucket on the ground and set up his rod next to Xu Shouyun.

The door closed, the television in the living room was also turned off, and the sound vanished.

Once the television sound disappeared, the surrounding environment became even quieter, with the rustling sound of the pen tip rubbing against the paper, and the low chirping of insects coming from outside the window.

On October 3rd, the chore of washing dishes had fallen onto Xu Qingzhou's shoulders.

"It's all circles and squares, plus all sorts of strange symbols; at first glance, it really looks like the real deal," Wang Xiaping said.

Because Xu Qingzhou had slept for over an hour on the plane last night, he really didn't feel sleepy now and planned to write for a while longer.

"Then why are you guys still wearing white clothes?"

"It looks good." Ding Jiahui never engaged in internal mental friction, only questioning others, "Look at you, you don't even know how to tidy yourself up."

When the four of them arrived, there were more than 10 people in the private room, and it was very lively.

Xu Qingzhou saw Zhang Yuquan standing in front of everyone at a glance; this guy was riding high, chatting happily with his classmates, and seemed more confident than he was in high school.
