With a soft creak, the door opened open.

Silence came over the air.

The scene in the No. 7 lecture hall seemed to be still in the chaos of yesterday, the paper was thrown on the ground at random and no one picked it up, and even the table that was crooked by him maintained the same appearance as it had been more than 20 hours ago, and no one straightened it.

If it weren't for the terrifyingly quiet air, Lu Zhou would have even thought that he was back to yesterday, to the scene that made his heart stop beating suddenly......

Seeing Lu Zhou looking at everything in the lecture hall without saying a word, the assistant standing next to him was a little hesitant to disturb him. But thinking about his unfinished lunch, he still took a deep breath and said in an inquiring tone

"I've brought you here, and if you want to stay a little longer, remember to close the door later. Key...... Is it to put me here? Or do you carry it? ”

"Give it to me."

Taking the key from the apprehensive assistant, Lu Zhou nodded lightly and said, "When it's used up, I'll return it directly to Professor Helch Holden, you can get busy first." ”

Professor Hellsch Holden is the Secretary General of the International Union of Mathematicians and one of the main leaders of the organizing committee of the conference, responsible for the scheduling of the venue and the handling of emergency situations.

After hearing that Lu Zhouhui would contact Professor Hatch Holden himself, the assistant breathed a sigh of relief, didn't say anything, said goodbye, and turned to leave.

The atmosphere in the lecture hall made him feel oppressive.

Especially the dried blood stains on the whiteboard......

He didn't want to stay here for a second.

After the assistant left, Lu Zhou entered the lecture hall, turned on the light, closed the door behind him, and then walked through the aisle strewn with paper and walked to the podium.

The blood stains on the whiteboard were distressing.

However, the most distressing thing is the dense lines of calculations.

As an expert in the field of mathematics, he knows exactly how hard it takes and how much effort it takes to make these results. It can even be said that even if it is himself, it is impossible to do it without ten days and half a month.

Especially under the torture of illness, Lu Zhou couldn't imagine how she spent this year.

However, it was precisely by seeing these calculations that Lu Zhou finally understood why she had been hiding from herself.

Perhaps, when she found out about her condition, it had reached an irreparable level. Otherwise, she doesn't have any reason to be treated negatively, and she doesn't have any reason to choose to hide it......

Unless there's really no way around it.

After all, the symptoms of cancer in the early stage will be similar to many common diseases, and her body is not very good, and it is difficult to detect the problem immediately with ordinary medical examinations.

And once symptoms appear......

It's basically late.

In fact, it is also the cause of death in more than 70% of cancer patients.

But......

“…… Why was she bumped into it? ”

Could it be that the Fields Medal really comes with a curse?

Staring at the equation on the whiteboard, Lu Zhou took a deep breath, and his pupils were filled with calm colors again.

The probability of expecting to get the anti-cancer miracle drug after completing the system task of the Riemann conjecture is too low. Rather than hoping for this, it is better to hope that because the Riemann hypothesis is solved, the patient will be in a good mood, and then the cancer cells will be completely destroyed, but it will be more "empirically based".

From the very beginning, he did not expect to solve the problem with the reward of the system's tasks.

To put it bluntly, the real value of this black technology system is not here, but in the system task itself!

According to the system, when he completes the current task, in addition to the option to continue the ongoing task chain, he also has three chances to re-randomize the task. According to the principle of task assignment, the tasks assigned to him are usually the problems he is currently facing or may face.

To put it bluntly, this thing is like an intelligent scientific research aid, referring to the development experience of future people or advanced civilizations, comprehensively analyzing his resources, social status and environment, and planning several scientific research routes with the highest investment and returns for him.

With his LV6 biochemistry grade and the fact that cancer is his most important apprentice, the probability of triggering a systematic task for cancer-related topics is as high as more than 90%.

Although he may be lacking in biological knowledge, scientific research is not a one-man job, and his shortcomings are made up for by talents in the Institute for Advanced Study.

What's more, in addition to the knowledge he can rely on, he also has money.

Being rich is also a superpower in itself.

Especially for a scientist who knows how to spend money.

On the whole, his chances of winning are still very good.

If even that's not possible......

It can only be said that this topic has exceeded the upper limit of the current technological level of the era and involves a series of problems that need to be solved urgently, rather than a problem that can be broken through by a surprise attack in this direction.

Taking a deep breath, Lu Zhou shielded all the distracting thoughts in his heart from his thoughts and said softly.

"You didn't finish the performance."

"Let me do it for you......"

Lu Zhou, who had completely calmed down, had completely entered the state.

This is probably the time when he really devoted himself to a problem and went all out to solve a problem.

It reminded him of the first time he went to Princeton for an academic conference years ago.

The world of the Enlightener, who had barely entered with the help of the system, was now easily stepped into by him in just one breath.

And almost at this moment, the equations and characters lying quietly on the whiteboard, like the elves that have been given life, weave into a symphony of fate composed by life, striking the strings of the theoretical harpsichord in the invisible storm, and converging into a passionate, unyielding, and destiny melody.

There is no audience.

Not even a musician.

However, the voice did reach Lu Zhou's ears, as if it crossed time and space, brought him back to the classroom in Princeton, took him back to that snowy night, and saw the snow woven of numbers again.

"I see......"

Taking in the calculations on the whiteboard, Lu Zhou nodded silently.

Not only the content of the paper, but also the part that is written haphazardly on this whiteboard is probably her unfinished research.

Many things are just abstract blueprints, or even outlines that can't even be described as ideas, and must be accompanied by detailed and complex narration in order to convey the content to the audience correctly......

However, for Lu Zhou, who passed on this knowledge to her bit by bit, it was not difficult to understand what she wanted to express.

Not to mention in the current state.

“…… The expansion formula [ζ(z)]-1/2=Σnαnn^-z of [ζ(z)]-1/2 is truncated, and a new series φ(z)=Σnβnn^-z is introduced to modulate the integrand of the three parts of the equation. ”

"It's no wonder that my research is stuck in a bottleneck and I can't find an exit. My attention was all focused on the improvement of complex advanced mathematical tools and methods such as the analysis of superelliptic curves and the introduction of differential manifolds into the complex plane as 'auxiliary lines', but I ignored some details and even basic problems. ”

It is no wonder that Chen Yang, who he dug from the Mathematics Research Center of Yan University, was able to dig up such a large room for improvement in his paper.

At that time, Lu Zhou didn't care, but now that he thinks about it, he may indeed have committed the most undesirable, "obvious" negligence - that is, when building a building, he only saw the height and scenery of the floors, but ignored whether the most basic stone bricks could bear this majestic project.

"It was indeed my negligence, and if I hadn't been away from teaching for too long, I shouldn't have made this mistake...... Of course, now is not the time to make excuses. ”

"In addition, although your idea is very novel, there are still some problems in details, such as the selection of N values at Equation 8, and the shortcomings of abstract spatial thinking ability exposed when introducing differential manifolds into complex planes."

"If it were me, I would do it......"

The most important thing here is the whiteboard.

Walking to an empty whiteboard, Lu Zhou picked up the pen that Vera had dropped on the ground from the side, and traced the map in his mind that was gradually becoming clear on it one by one.

Time and space seem to freeze.

Everything that has nothing to do with this is excluded.

If the "performance" of the first half is like a storm beating on the eaves of the window, then the performance of the second half is like a river where thousands of streams converge, breaking the embankment that blocks the road, clamoring with boiling waves, and rushing into the sea in a thunderous roar.

And one wave has not settled, and one wave has risen......

The silent performance lasted for a long time, far more than forty-five minutes, or sixty minutes.

Hungry, there is still some liquid food left in the space.

Sleepy, there are energy potions to replenish.

The labyrinth had trapped him for too long, and now it was the closest he was to the finish line.

If you give up this time......

If you want to wait until next time, you don't know when you'll have to go.

Time passed minute by minute, and the sun outside the window did not know how many rounds had passed, and Lu Zhou's attention was not there at all, just quietly facing the eighth whiteboard that had been filled and wiped many times.

Finally, in the depths of the pitch darkness, Lu Zhou, who was constantly searching, finally saw a light.

That light.

As if from the void.

Staring at the void, Lu Zhou's pupils dilated slightly, and then slowly contracted.

There is no pride in the clouds......

There was no ecstatic cheer either.

Some of them are just as calm as they were.

And, a touch of bland relief.

"I see."

"It's no wonder that all the climbers of a century and a half can be buried."

"It's really not something that can be solved by talent or knowledge alone."

Who would have thought that the eight-page paper from the former Berlin Academy of Sciences in the small town of Breslentz in the Kingdom of Hanover would bury so many talented scholars.

Nor would anyone have imagined that more than a thousand mathematical propositions based on the validity of the Riemann hypothesis or its generalized form would be elevated to theorems at this moment.

Now, a century and a half later, someone can finally answer the question of the century in the place of Gauss.

Yes, Professor Riemann is right.

Closing his eyes, Lu Zhou took a deep breath and exhaled the turbid air in his chest.

Then, he looked at the camera in the corner and paused.

"Xiao Ai."

"Help me sort out the things on the whiteboard."

"Just upload it to Arxiv."

He knew that during these days, Xiao Ai had been silently watching over him behind his back.

He even knew that the reason why the door was not pushed open must be because Xiao Ai knew that he didn't want to be disturbed, so he used his address and tone to send an email to the person in charge of his security.

Sure enough, the phone in his pocket shook, and a string of bubbles popped out.

【Roger!】 (??????)?? 】

[Congratulations to the host, mua! (///ω///)】

After doing these things, Lu Zhou took out a tube of energy potion from the system space, unscrewed the cap of the bottle and drank it in one gulp, and then stuffed it back into his pocket.

He hadn't slept for three days, and he wasn't in a hurry to go to sleep.

Holding the podium with both hands, Lu Zhou sat up and quietly faced in front of him, and eight whiteboards were lined up.

He just wanted to sit here now, quietly waiting for that familiar voice to sound from the bottom of his heart......

Then, make a decision on the next step.
