Chapter 445

The next day.

"Xu Qingzhou, get up." Song Yao pulled her foot out of her slipper and kicked her boyfriend, who was sprawled out on the sofa.

Xu Qingzhou had two dark circles under his eyes: "Don't want to move..."

Having been tired for half the night as well, School Beauty Song looked full of energy.

"Serves you right."

Looking at her boyfriend's wilted state, Song Yao suddenly felt a sense of victorious joy. That's what he got for torturing her so much last night.

She walked to the bedroom, took out the high school uniform from last night, washed it, and hung it up to dry.

Xu Qingzhou closed his eyes and chuckled to himself. Last night, he didn't know who it was that kept begging for mercy, saying they were tired.

The only regret was that he didn't manage to help School Beauty Song.

This girl was strictly on guard; the two of them were at a stalemate for a while, which eventually turned into his own entertainment session.

He lay there for a while, and his phone rang.

He answered, and Professor Gu's full-voiced tone came through the microphone: "You solved the Riemann Hypothesis?!"

"News travels fast..." Xu Qingzhou was surprised.

"You kid are always so unexpected..." Gu Zhizhong didn't know how to describe it for a moment; he had crashed through another south wall.

He asked: "What about the paper? When will it be out?"

Xu Qingzhou pondered for a moment and said: "The proof is quite complex; the complete paper... four or five days, I guess."

Gu Zhizhong nodded and asked in a deep voice: "Your efficiency is as high as ever. Fine, I'll wait for your paper. You're graduating soon; what are your plans for the future?"

"Stay here for another year. You know, my girlfriend doesn't finish her exchange program until next year." Xu Qingzhou turned his head to look at School Beauty Song, who was hanging clothes on the balcony.

Her long hair was tied with a rubber band. If it were any other time, Xu Qingzhou would definitely have said, "Madam, this hairstyle is a bit dangerous," but now he just wanted to conserve his energy.

"Hmm, find some time to come back to Jingda and pick up your graduation certificate and degree certificate," Gu Zhizhong said with a smile.

"Alright, I'll come back once I'm done with this busy period."

Xu Qingzhou nodded.

Gu Zhizhong didn't say much more: "Alright, you kid must be very busy now. That's it. You must be very tired these past few days. Young man, you still need to pay attention to rest; don't work so hard."

"It is quite tiring..."

"Get some good rest."

Jingda, Gu Zhizhong's office.

"Phew~"

Dean Nie Zuozhen breathed a sigh of relief and chuckled, "It's good that he's coming back."

"I told you long ago that this kid wouldn't run away." Gu Zhizhong sipped his tea, his pride undisguised between his brows. This kid was different.

"No choice, our Xia Nation has lost too much talent, especially in mathematics..."

Nie Zuozhen was helpless. After finishing his tea, he clapped his hands and stood up, saying: "I have to go to a meeting."

"A meeting late at night?"

"Yeah, and it's all because of your precious student. Graduation is a small matter; we need to discuss what kind of treatment to give him... After all, he will be the first homegrown Fields Medal winner in Xia Nation."

"Good."

Gu Zhizhong nodded with a smile.

United States.

It was just morning. After Professor Stewart arrived at his office, he first brewed himself a cup of coffee.

He had been in quite a good mood these days.

That Xia Nation person hadn't made a move for two whole weeks. If nothing went wrong, this would be a blunder that people could talk about with relish.

Just like his proof of the Polignac Conjecture last time.

"Sigh~"

If it weren't for Xu Qingzhou... the honor for the Polignac Conjecture should have belonged to him.

Half a year, no, three months, and he could have fixed the proof.

What a pity...

Although he later found another way to prove it, people were always only willing to remember the first person to climb Mount Everest.

Just at this moment, he saw his friend enter with a strange expression and asked with a smile: "Is it news about Xu Qingzhou?"

"Hmm."

In addition, some people said they had completed the construction of his equivalence theorem and hoped he could take a look and get approval.

Professor Stewart asked with a smile: "With that expression, did he publish his paper on the zero estimate?"

"Not at all."

The friend shook his head again and handed his phone directly to Professor Stewart.

"It seems just as I said, Xu Qingzhou merely gave us a blank check. Young people, after all, are... hmm?"

Professor Stewart's words came to an abrupt halt; his eyes widened, and he shouted in disbelief: "Proved the Riemann Hypothesis?!"

The friend nodded and sighed: "Tobien went to the scene with friends. Although there were many places that were hard to understand and it felt whimsical, no problems were found."

"..."

Professor Stewart's face turned dejected.

"Bro, to be honest, losing to such a person is not a shameful thing."

The friend looked into the distance and shrugged: "At the very least, while we are still alive, we can see the truth of the Riemann Hypothesis."

"Perhaps."

Because he needed to hurry and finish the proof paper for the Riemann Hypothesis, Xu Qingzhou and Song Yao's travel plans had to be pushed back again.

May 8th.

Xu Qingzhou threw the organized paper onto arXiv and packaged this paper together with the previous Riemann-Siegel zero paper to submit to *Inventiones Mathematicae*.

"Phew~"

Finally done.

Xu Qingzhou stretched and scooped up Er Miao, who was napping on the table.

Er Miao struggled symbolically to express its dissatisfaction with Xu Qingzhou disturbing its sleep, but soon squinted its eyes in Xu Qingzhou's arms, purring.

Song Yao was busy dealing with her paper during this period, returning to her routine of leaving early and returning late.

6 PM, still early before picking up Song Yao.

The group chat was quite lively.

Xu Zhengyang was asking how he had been lately.

"It's time to report that I'm safe to everyone."

Xu Qingzhou frowned, thinking that besides these friends, there were also the vast number of netizens who cared about him, so he simply took out his phone to edit a Weibo post.

【One piece of bad news, one piece of good news.

Bad news: Unfortunately, I can't produce the paper on the Riemann Hypothesis zero estimate.

Good news: I've uploaded the Riemann Hypothesis proof paper; everyone can just make do with reading it.】

At this time, Jingda, Xia Nation.

On May 4th Road, three people were wearing slippers, walking with a lazy, old-man gait, somewhat... out of place with the exquisitely dressed young men and women around them.

"It's still more comfortable to dress like this." Xu Zhengyang sighed. In the past, he had to dress up when going out, but now he just went with whatever was comfortable.

Old seniors, with no scruples.

In the blink of an eye, their four years of undergraduate life were coming to an end. After graduation, they would have to go their separate ways. The three people who were usually busy with their own things had been gathering together quite often during this period.

"Old Kong, white, right?"

Xu Zhengyang leaned closer to Kong Xianbo and asked in a low voice.

Kong Xianbo retracted his gaze from the big white legs in the distance without a trace and said proudly: "Nonsense, what white or not white? I'm thinking about how to revise my paper."

"Old repressed pervert."

Xu Zhengyang rolled his eyes, his gaze falling on the legs in front: "It's the season where there's beautiful scenery everywhere again..."

Old Kong: Pfft~

Old Zhai used to have the heart of a thief but not the guts, occasionally taking a peek, but now that he had a girlfriend, that was called loyalty; he didn't even take an extra look.

What a pity, Old Xu wasn't here; they were missing a like-minded person who could share a knowing smile.

Xu Zhengyang shook his head and muttered: "Old Xu hasn't spoken in the group chat for a while. What is this old kid busy with all day?"

"Maybe thinking about how to show off." Zhai Ziqiang said.

"This time... it's been more than two weeks since Old Xu announced that new estimate. Could Old Xu have really crashed?"

Xu Zhengyang was a bit worried.

Although he despised Xu Qingzhou's showing off, that was a matter between them; when it came to facing outsiders, they didn't hesitate at all.

"When I asked last time, he told us to stay steady."

Kong Xianbo paused and sighed: "Some people online are saying very nasty things. I even argued with two traitors last time."

Xu Zhengyang didn't care: "They're just trolls who can't stand others doing well... Now that you mention it, I remember the argument from last night isn't over yet. This dead troll actually said Old Xu was all show and no substance."

Ding~

The phone vibrated.

"Hey, Old Xu posted on Weibo."

"What did he post?"

Soon, all three of them put down their phones almost at the same time.

"Old Xu, awesome."
