As it turned out, Lu Zhou's premonition was correct.

I don't know what crazy it was, but Molina really came downstairs to his hotel.

Everyone came, and Lu Zhou couldn't refuse, so he had to take her to the bar on the second floor of the hotel.

Different from ordinary bars, this kind of five-star hotel comes with a bar, not so much a bar is actually more like a restaurant, and the service object is more inclined to business people, so not only is the decoration more modern and elegant, but the music in the bar is also based on piano music, violin and saxophone.

Of course, the liquor that is usually served in bars will also be served here, although many of them will not be written on the menu.

Lu Zhou ordered a bacon burger and a glass of German dark beer, and then watched the guy order a bunch of colorful cocktails, without saying a word, and poured himself cup after glass.

Finally couldn't stand it anymore, Lu Zhou couldn't help but persuade him.

"Drink less, drinking hurts your brain."

How can there be such a drink, not to mention ordering a bunch of colorful cocktails as soon as you come up, and you will look like a novice.

"I invite you."

"It's not a question of who invites whom...... Even if you insist on asking, I won't object to it. ”

Molina: "Why is that?" ”

Lu Zhou: "The way you look will make me think that you want to plot against me." ”

After a pause in the cup in her hand, Mo Lina, who was drinking, frowned, and said with a somewhat unclear mind.

“…… What are the plots? ”

It's over, it looks like it's too late.

This not very smart Yazi is probably about to drink it.

Lu Zhou sighed.

“…… Nothing, when I didn't say. ”

After drinking the "sunrise" in the cup in one gulp, Molina's eyes were stained with a trace of confusion.

stared at the direction of the bar for a long time, and suddenly said to her with a side face to the landing boat.

"I only found out today ......"

Taking a bite of the burger, Lu Zhou asked casually.

"Know what?"

After being silent for a long time, a trace of struggle flashed in her confused eyes, Molina suddenly sighed, put the cup back on the table, and said abandonedly.

“…… Nothing, when I didn't say anything. ”

Lu Zhou: "......??? ”

Why are you kidding me?

Without an explanation, Molina took out a handbag from the side and placed it heavily on the table.

"These things, here you go."

Lu Zhou: "...... What is this? ”

"The ancestral stuff is mainly Professor Abel's notes. By the way, there are a few pages on it that have been drawn with ballpoint pens...... I accidentally got it when I was a kid, so you don't have to worry about it. ”

I don't know why, when it comes to "ancestral", Mo Lina almost gritted her teeth and squeezed this sentence out of between her teeth, so that Lu Zhou is not sure if she made such a decision when she was drunk.

Looking at the handbag on the table, Lu Zhou said with a little hesitation.

“…… Is it really good for me to give me something so important? ”

After taking a sip of cocktail, Molina slammed the empty glass on the table without an image and said with a blank face.

"It's okay, I don't need them anymore...... Anyway, it's all a mess. ”

Looking at the resolute expression on Mo Lina's face, Lu Zhou was silent for a while, and finally sighed and said.

“…… Then I'll keep these things here for now, and don't be embarrassed if you plan to come back and send me a message. ”

"Rest assured, there will never be a day, seeing these things will only upset me...... I went to the bathroom. ”

With that, she drank the last glass of wine in a clean gulp, and Molina staggered to her feet with her hands on the table.

However, before she could straighten her knees, Lu Zhou saw her kick forward with both legs, and she sat back on her feet.

His head slammed on the table, and he didn't hear her cry out in pain, so he fell straight on the table unconscious, and he was dumbfounded when he looked at Lu Zhou from the side.

Is this a fragment?

It was expected, but it was too sudden.

Looking at the unconscious Mo Lina, Lu Zhou had a speechless expression.

What about inviting me to drink?

Why did it end up being my treat?

“…… Forget it, for the sake of this gift, this wine is mine. ”

Looking at the handbag on the table and sighing, Lu Zhou reached out and pressed the electric bell on the table and called the waiter to the side.

Although all the expenses in the hotel can be counted into the room rate, he is not the kind of person who likes to take advantage of the public, and he does not lack that money, so he still insists on swiping the card to buy the bill.

Looking at Mo Lina lying on the table, the waiter smiled thoughtfully and said.

"Sir, do you need to check this lady in?"

Wiping his mouth with a napkin, Lu Zhou said casually, "Well, I'm sorry for you." ”

"Yes sir."

At this moment, Lu Zhou suddenly noticed the ambiguous smile on the waiter's face, reacted in an instant, coughed lightly and continued.

"I mean, help her open another room...... Also, please help find the two ladies and throw her in. ”

Realizing that he had misunderstood, the waiter immediately showed an apologetic expression on his face and said in an apologetic tone.

"Yes, sir."

……

After taking a plane of tens of thousands of kilometers, Lu Zhou originally planned to go to bed early, but a large glass of beer and a hamburger in his stomach made him unable to sleep at all.

Lying on the bed tossing and turning for a long time without feeling a little sleepy, Lu Zhou simply didn't sleep, took out the notes in the handbag, and flipped it up with interest.

The notes are rather confusing, and are more of a diary of mathematical drafts and inspirations than research notes.

Although he has the habit of writing down his inspirations at will, he is still a little different from this professor Abel, at least he will never mix academic matters with trivial things in life.

However, Professor Abel seems to be more casual, not only likes to intersperse some of his thoughts on poverty and life in the academic content, but also seems to be quite concerned about the situation in the Mediterranean and the movement to extract teeth from the West.

It reminded him of an old friend, Professor Tao, who teaches at the University of California, and in that respect, the two are really very similar. It's just that one is written in a diary, and the other is written on a personal blog.

For example, when Lu Zhou flipped through one of the diaries, the previous page still wrote that Professor Abel had his wallet stolen and cursed the thief while riding the train, and the next page turned into a reflection on the proposition that "there is no general form of algebraic solution to a general algebraic equation higher than the fourth degree".

This proposition, which seems almost taken for granted now, was equivalent to today's millennial problem at that time, and it has existed and puzzled the mathematical community for two and a half centuries in history far back in history than the Riemann conjecture.

By the way, this proposition was solved by him in 1824, and judging by the time in the footer of his diary, he wrote these things exactly at the end of 1823.

As for the Riemann conjecture......

Dr. Riemann, who proposed it two years later, was born in a small town in the Kingdom of Hanover, and it would take another twenty years for him to move from the study of theology and philosophy to mathematics.

In fact, 19th-century mathematics was far behind the curve.

Even a genius like Abel, due to the limitations of the times, it is impossible to say that he left any surprising discoveries on the notebook, and Lu Zhou did not have any hope for this.

However, although it is impossible to discover new mathematical theorems or propositions, as a great man of the times, his mathematical ideas are still worth excavating.

You can't tell, but you'll find something interesting.

And Lu Zhou was also very curious about what this short-lived genius studied at the last moment of his life.

Turned the next page, but at this moment, Lu Zhou's index finger and thumb pinching the footer suddenly paused.

“…… This is. ”

It was a sketch, I don't know if it was drawn with charcoal or pencil.

Obelisk-like "stone monuments" stand on the ground, and the endless wilderness stretches towards the edge of the blur......

The moment he saw this painting, Lu Zhou's pupils suddenly contracted.

This painting!

He's seen it before!

Although it is not in the form of a painting......
