Outside the window, the sky lit up.

Lu Zhou, who was sitting at the desk, took a deep breath and let out a sigh of joy.

A lot of things are like this, and there is only a layer of window paper between what you understand and what you don't understand.

If you can't break it, it's a flower in the fog.

And if it is punctured, everything is clear at a glance.

At this moment, in the computer screen, it is the paper on the process of solving the general solution of the Yang Mills equation.

Compared with the L-manifold to introduce differential geometry to prove the existence of the solution of the nonlinear partial differential equation, the process of solving the general solution is surprisingly simple, and the main proof part is even completed in only ten pages.

Of course, part of the reason for this is that this direct reference to the conclusion omits a lot of tedious repetitive derivation process by using several inferences already proven in the previous paper.

Before submitting the paper, Lu Zhou, who couldn't wait to share this joy with other scholars, sent the paper to the mailbox of the editorial office of the Annals of Mathematics, and hung the preprint on Arxiv.

After doing these things, Lu Zhou stretched, got up from his chair, and went downstairs to the bathroom to take a hot shower.

He hadn't slept all night, and his biological clock was disrupted, and he didn't feel sleepy at all.

In order not to reverse the day and night and affect tomorrow's work, he plans to stay up until noon and take a two-hour nap, and then go back to sleep normally at night.

After coming out of the bathroom, Lu Zhou changed into clean clothes, went to the kitchen to make himself a cup of coffee, took out a frozen sandwich from the refrigerator, and was about to stuff it into the microwave. But at this moment, the doorbell rang at the door.

Stopping his hand that was about to reach into the microwave oven, Lu Zhou looked at the drone squatting on top of the refrigerator and asked casually.

"Xiao Ai, who's out there?"

Soon, synthesized electronic sounds wafted from underneath the drone.

"It's your personal doctor, master."

Yan Yan?

What is she here for?

Stuffing the sandwich back into the refrigerator, Lu Zhou instructed Xiao Ai to open the courtyard door, and then walked through the living room to the entrance.

The door opened, and I saw Yan Yan standing at the door with a plastic bag in her hand. The dress in the school hospital is different, the white coat is replaced by a purple and black T-shirt, and the casual jeans on the lower body also add a bit of youth and beauty that she has never seen before.

However, compared to what she was wearing, Lu Zhou's attention was more on the plastic bag she was carrying.

Although it was tightly tied and he couldn't see what was inside, from the outline and the overflowing fragrance, he could immediately guess that it must be his favorite xiaolongbao and soy milk.

"Why are you here?"

Shaking the plastic bag in her hand, Yan Yan said something terrible in a relaxed tone.

"I'm afraid that no one will know if you're cold at home, so Wang Peng called me and asked me to come over and bring you some food."

What the hell is cold?

Lu Zhou, who decided to ignore this detail, sighed and said, "Why didn't he come himself?" ”

Yan Yan: "He also said that if something happens, my rescue experience is more professional." ”

Lu Zhou: "......"

Isn't it because the last upgrade was too fast, and I used too much force and fainted once?

It makes me feel like I'm going to get cold at every turn.

But in any case, this is also a good intention.

Taking the breakfast from Yan Yan's hand, Lu Zhou sat at the dining table and took a bite of xiaolongbao, while taking out his mobile phone and opening the scarf. Originally, I was going to see if there were any interesting hot searches, but I found that the entry of Yang Mills' equation was hanging on it.

clicked in with interest, and casually found a scarf for online news, Lu Zhou found that the comment area was unexpectedly lively.

There are congratulatory fans in it, a repeater who brushes 666, and inexplicable abuse...... But he just glanced at these things, and after reading them, he smiled, and he didn't take it too seriously.

After all, he has also grown a lot in the past few years.

Compared with his past self, he has already seen those praises and slanders very lightly.

I praised all those who praised themselves for being handsome, and the breakfast was almost finished.

Picking up a tissue and wiping his mouth, Lu Zhou, who got up from the chair, put the garbage into a plastic bag and tied it up, looked at Yan Yan who was sitting on the sofa and said.

"I'm going to go to the Intercontinental Hotel in a moment."

Yan Yan nodded and stood up.

"I'll send you there."

Hearing this, Lu Zhou glanced at her in surprise.

"You know how to drive?"

Yan Yan raised her eyebrows.

"Don't believe me?"

Lu Zhou coughed lightly.

"Not really."

It's just that he was in the female driver's car, which made him a little panicked.

……

It's not just Lu Zhou who hasn't slept all night.

At this moment, more than ten kilometers away at the Jinda Supercomputing Center, a group of engineers in computing science have been busy all night.

Sitting in the office next door waiting for the final result, Xu Jian had already smoked several cigarettes in a row, and his eyes glanced at the door from time to time.

At the end of yesterday's report meeting, after handing over the matter of settling the visiting scholars to the vice president and Dean Qin, he came here with several professors from the School of Mathematics who were doing PDE and the general solution written by Lu Zhou on the blackboard, and verified the correctness of the general solution with the help of supercomputing.

And by now, more than a dozen hours have passed.

With so many manpower and computing resources concentrating, it's time to get results.

However, so far, there has been no movement in the computer room......

This feeling of fidgeting can't help but remind him of the time when his wife gave birth

Taking a deep breath, Xu Jian pressed the burned cigarette butt into the ashtray, ready to go to the side to ask about the result.

However, just as he reached the door, the door of the lounge was pushed open, and two information technology engineers walked in with serious expressions.

Seeing the serious expressions on the faces of the two, Xu Jian suddenly chuckled in his heart, and hurriedly stepped forward to ask.

"Are the results out? How's it going? ”

The engineer said, "The results are out, I hope you are mentally prepared." ”

A hint of bitterness appeared on his face, Xu Jian took a deep breath, and Zhengse said.

"Say it."

The two engineers exchanged glances, and the man who spoke earlier continued, "The result was beyond all of us...... That general solution to the Jan Mills equation is exactly right! ”

Xu Jian: "......??? ”

Hearing that sentence was completely correct, Xu Jian almost didn't spurt out a mouthful of old blood.

Hold the grass! What the hell is right, why are you giving me a straight face? I thought it was a mistake to calculate it in the end!

But at this point, he didn't care about blaming the two engineers, and the excitement that welled up in his heart made him laugh out loud.

Looking at Principal Xu, who suddenly laughed, the two engineers looked at each other.

This guy ......

You can't be crazy.

Stopping to catch his breath, Xu Jianqi looked at the assistant who was sitting with him in the office and ordered.

"Contact the Claims Department immediately, we will be in front of everyone and announce the results of the inspection!"
