After the concert, as usual, there is time for the audience to interact with the performers.

For a popular star like Su Xue, the organizers arranged a separate press conference room for her, and at the same time strengthened security to ensure that nothing went wrong.

Struggling to move forward in the crowd, Li Yan finally entered the encirclement, entered the hall after the security check, and went to express his admiration for the goddess in his mind. What about Long Yun? But he was not in a hurry, put the ticket in his pocket, and found a less crowded place to sit down, still reminiscing about the performance just now.

The level of the concert just now was quite good, especially Su Xue's piano solo, which made him, a layman, fascinated by it.

I don't have any artistic talent, and I can't find the feeling of playing and singing with my hands that are used to the keyboard, but Long Yun actually likes to listen to music, especially classical music, and he always feels that the sound produced by the instrument is purer than the human voice. As for the pop songs of various genres now, they sound like hearing killers, and Long Yun asked himself if he was capable of appreciating them.

Thinking casually like this, Long Yun looked up at Su Xue who was sitting at the front of the hall platform. With Long Yun's eyesight, although the distance is still relatively far, the girl's smile can be seen very clearly.

After just a few glances, Long Yun came to the conclusion that this was indeed an otherworldly beauty. "Su Xue", this is supposed to be a Chinese name, but Long Yun can see that she should be a mixed race from Eastern Europe: quite handsome facial lines, high nose bridge and slightly convex eyebrow arch, a delicate face that combines Eastern and Western features, seems to have infinite charm. Seeing the girl's voice and smile, whether it is her body appearance or dignified and quiet temperament, it is rare in ten thousand.

After communicating with the fans for a while, and seeing that the atmosphere in the venue was still quite warm, Su Xue waved her hand elegantly and signaled everyone to be quiet.

"Ladies and gentlemen, are you interested in playing a game of guessing numbers?"

"Guess the numbers? All right! A lot of people shouted out with joy.

As Su Xue's fans, they all know that this beautiful girl also has a special ability - mind reading. Although Long Yun didn't know, after listening to Li Yan's introduction, he also understood a little bit.

The so-called guessing the number is to ask the guest to think of a number, and then freely perform simple addition, subtraction, multiplication and division operations, the process of operation needs to tell sù Su Xue, but there is no need to tell sù the result of each step, only need to tell her the final result of several steps of operation, she can accurately guess the number in his mind.

Now, there is a young man who looks like a student who is quite excited, and he is interacting with Su Xue like this.

"I've picked the numbers. I add 17, then multiply by 3, then subtract 4, divide by 2, add 9, and divide by 5. Well, okay, now I get 8! ”

Smiling and listening to the young man's statement, Su Xue replied in a soft voice as soon as the words fell.

"You've got the number 5 in mind, right?"

"Yes, yes! - It's amazing! ”

"Look, you guessed it again! She's so good, she seems to be able to guess people's hearts! ”

"Oh, that's kind of interesting."

Long Yun smiled in response. After the demonstration just now, Long Yun has already gained insight into the secret of this game.

In fact, this beauty who seems to be able to see through people's hearts just sets up a unary equation in her heart, constantly modifies it according to the questioner's calculations, and finally only needs to solve the equation. Let's just say that this time, in a mathematical form, it is nothing more than that:

x； x+17；3x+51；3x+47；1.5x+23.5；1.5x+32.5；0.3x+6.5。

Finally, the questioner tells her that he gets 8, so it is 0.3x+6.5=8. Isn't it clear that if you solve the equation, you will know that x is equal to 5.

It's a bit unreasonable to play such a simple game, but many people don't know the principle. Thinking of this, Long Yun suddenly moved his mind; He knew that there was a loophole in such a number-guessing game, and now he was going to try it. So Long Yun also raised his hand, but there were many people around him who raised their hands to ask questions, and he didn't have any hope.

"Okay, the man in the penultimate row, yes, the one in the blue shirt, please ask."

I? Long Yun was a little surprised, his luck was quite good today.

Standing up a little restrained, Long Yun cleared his throat and asked his question.

"I picked a number, added it to 8, divided it by 3, then added 10, multiplied by three, subtracted the number itself, and finally added 9. Now I get 47, pls what is the number I want? ”

Hehe, what are you going to do now?

When the calculation was reported just now, Long Yun had already calculated the whole process in his heart:

x； x+8；x/3+8/3；x/3+38/3；x+38；38； 47。

When calculating, the independent variable, that is, the number he had in mind, had been eliminated; Now no one knows that the number I chose is 7 except for me, and Long Yun is very sure about it. He looked at Su Xue and waited for her answer.

"Oh. I guess the number you picked was 7, didn't you? ”

――！

Standing on the spot for a while, Long Yun, who had excellent eyesight, could clearly see that Su Xue's bright eyes were looking at him, and the corners of her mouth seemed to be a little bantering.

How did she know?

That's impossible!

Applause and whistles rang out in the crowd again, and seeing that Long Yun was still in a daze, everyone knew that Su Xue had guessed correctly this time.

A little embarrassed to admit Su Xue's mind-reading skills, Long Yun sat down blankly, he really couldn't understand what was going on. Could it be that this Su Xue really has such a special function? But that kind of unwarranted supernatural phenomenon, Long Yun categorically did not believe it. It's so weird!

Towards the end of the exchange meeting, Su Xue got up and put down the bouquet and began to walk down the stage to sign autographs for everyone. Many fans present were looking forward to it, and at the same time worried that they would miss it, so they were quite excited to wait for her to come over.

At this time, Su Xue carefully pulled the hem of her skirt, and slowly walked between the rows of seats patiently, writing his name for every fan who wanted to sign an autograph. Seeing that Li Yan was asking for an autograph, Long Yun felt that this musician was quite approachable, so he also took out the notebook he had prepared.

Watching Su Xue, who was wearing a long skirt and a long figure, getting closer and closer, and finally came to him, a faint fragrance hit, and Long Yun, who was not good at dealing with girls, had a strange feeling in his heart inexplicably.

He handed over the notebook and pen.

Reaching out to take his notebook, Su Xue looked at him with a smile, bowed her head and prepared to write.

However, there was a subtle change in her countenance, as if she had sensed something that surprised him inexplicably; After a quick glance around, Su Xue's eyes stayed on Long Yun. Between the flow of her eyes, she looked at Long Yun quite carefully for a while, and her lips seemed to be muttering lightly, which made the people around her who saw this scene feel very strange.

Seeing Su Xue's puzzled eyes, Long Yun became even more uncomfortable. He couldn't hear anything clearly, what was she talking about?

Fortunately, Su Xue still let him go, raised his hand to sign his name on the notebook, and then handed the notebook back to Long Yun with both hands. Feeling the strange gazes of the people around him, Long Yun hurriedly put away the notebook and sat down calmly.

"Hey, Long Yun, what did Su Xue see you do just now?"

"I don't know."

Long Yun shook his head suspiciously, he was telling the truth.

"She spoke to you? Isn't she interesting to you, Long Yun? ”

"Is there one? I don't know, I didn't hear clearly. ”
