Chapter 155

Su Xi: "Teacher Gu, come out at night just for dinner!"

Gu Lu: "Tonight?"

Su Xi: "Yes, you forgot, I still owe you a meal." This time it's my turn to treat you, Teacher Gu must give face!"

Gu Lu pondered for a few seconds and typed in the message, "Okay, send me the time and place, you must arrive on time." ”

Six o'clock in the evening.

Gu Lu walked out of the gate of Yan University and took a taxi.

"Master, Maxim's Restaurant. ”

Maxim Restaurant, located near the Chongwen Gate in Yanjing, is a Western restaurant with a long history.

It is very famous in the field of food and drink in Yanjing, and it has been in the top ten of Western restaurants all year round.

But it's not too expensive.

The per capita consumption of a meal is only about 500 yuan, which is still enjoyable for white-collar workers with petty bourgeoisie.

Su Xi had already booked a place in the restaurant.

And I was waiting here half an hour before the appointed time.

Under the guidance of the waiter, Gu Lu saw Su Xi sitting at the dining table, with one hand on his chin and one hand boredly scrolling through his mobile phone.

"Came so early?" Gu Lu smiled lightly, took off his coat, and sat opposite Su Xi.

"Ah, here you are. Hearing Gu Lu's voice, Su Xi raised his head in surprise, and then replied to Gu Lu's doubts with a smile, "Is it in the eyes of you men, it is normal for us women to be late." ”

"Uh...... That's true. Gu Lu did not deny it.

"But I'm not like them. Su Xi raised his hand and called the waiter, staring at Gu Lu with a pair of sparkling eyes, "I never let the people I care about wait for a long time." ”

Gu Lu coughed lightly, "Let's order." ”

Su Xi also seemed to have happened something, picked up the menu and reported the name of the dish, "Two musical steaks, two chocolate ice cream, one wild mushroom cream mushroom soup, one saffron prawn, and a bottle of white wine......"

Maxime's restaurant focuses on French cuisine.

Moreover, the layout of the restaurant is also in the French romantic style, which is very suitable for couples to go on a date.

In the center of the restaurant, there is a piano.

A tuxedo-clad player plays a romantic and melodious song.

"Hello sir, this is the musical steak you ordered. ”

A waiter politely placed the medium-rare steak in front of Gu Lu.

"Musical steak?" Gu Lu sighed softly.

Su Xi explained, "The Wagyu beef used in the steak of this restaurant will invite special musicians to play music when raising cattle to make the body and mind of the cow more pleasant through music, so it is called musical steak." ”

"Does that taste better this way?" Gu Lu asked.

"No, it's going to be more expensive!" replied Su Xi.

Gu Lu: "......"

Cut off a small piece of steak and feed it to your mouth with a fork.

Gu Lu chewed carefully and tasted it.

Really......

There is no difference in taste from ordinary steak.

While Gu Lu and Su Xi were eating, they chatted with each other.

Su Xi mainly talked to Gu Lu about the decoration of the store.

At present, the five new stores are almost completed, and after this time, when the stores open, Su Xi, the Yanjing regional manager, can easily come down.

"By the way, Gu Lu, what have you been busy with all this time?Shouldn't the university teacher's classes be very leisurely?" Su Xi looked at Gu Lu with a curious expression.

Su Xi knew that Gu Lu was very busy, but he didn't know what Gu Lu was busy with.

Gu Lu explained with a smile, "I am busy with a topic, the second problem of the minimum model program of double rational geometry, and I am currently stuck on the problem of how to prove whether the flip operation is terminated after a finite number of times. ”

"I don't understand. Su Xi shook his head in confusion.

"You came from a finance background, so it's normal that you don't understand these math terms. Let's talk about it......" Gu Lu was just halfway through his words, when he heard the melodious music in the restaurant suddenly stop.

Gu Lu looked at the piano in the center of the restaurant, and a young man was talking quietly to the man in a tuxedo.

Then the tuxedo man got up and made way for the young man.

The young man sat down and spoke loudly to everyone in the restaurant, "Today is my girlfriend's birthday, and the song "Dream of Love" is dedicated to her!"

At a dining table, a girl with ball-like hair and a little baby fat lowered her head shyly.

The customers in the western restaurant applauded very cooperatively.

The young man took a deep breath and placed his ten fingers on the black and white keys.

Then, melodious music sounded.

The young man was obviously an amateur piano enthusiast, and his playing level was obviously not as good as the tuxedo just now.

But it still stumbled and played it completely.

The crowd applauded again with encouragement.

The young man bowed to the crowd in thanks, and then walked over to the little girl.

Of course, the little girl with the head of the ball was moved, and gave the young man a big hug on the spot.

Then......

Then there is the picture that is not suitable for children.

Su Xi held his chin, looked at the little couple on the dining table over there with envy, and sighed, "It's so romantic!"

"Teacher Gu, do you know how to play the piano?" Su Xi stared at Gu Lu with sparkling eyes.

"A little bit. Gu Lu glanced Su Xi up and down, and said in a puzzled tone, "You...... What do you want to do?"

"Go up and play a song. Su Xi looked at Gu Lu with a smile.

Gu Lu shook his head, "I play the piano very well." ”

"I don't care. ”

"Also, the style of my piano music is a bit strange. ”

"It's okay. Su Xi followed the temptation, "Go up and play a song, Teacher Gu." ”

"Then I'll go?"

"Go, go, come on, I'll applaud you. ”

Gu Lu got up, tidied up his clothes, smiled apologetically at the tuxedo player before he could sit back in his seat, and sat down in front of the piano.

The tuxedo man made a gesture of invitation to Gu Lu.

Seeing someone sitting in front of the piano again, the customers in the restaurant were still a little surprised, this kind of incident was originally a small probability, but I didn't expect to encounter two cases in one day.

"A piano piece for my friend Su Xi. ”

Su Xi smiled sweetly.

She didn't dare to expect a difficult piano piece like "To Alice", even if Gu Lu played the simplest "Happy Birthday" song, she would be happy.

Gu Lu pressed the keys with his ten fingers, and the music sounded.

Midodos are swishing......

Gu Lu played very smoothly.

However, when everyone listened, they had a very strange feeling.

The music isn't bad, but it's ...... They just think it's weird.

Many of the fragments are fragmented, with no sense of continuity.

Seem...... It's not a piano piece.

Moreover, this song, everyone does not feel familiar at all.

What is this piece called?

The people were puzzled.

After finishing the song, Gu Lu returned to Su Xi's side.

"What's this song called?" Su Xi looked at Gu Lu with an inexplicable meaning on his face.

Gu Lu replied, "π"

"π?" Su Xi was a little confused.

Gu Lu nodded, with a serious tone, "This was taught to me by a senior brother abroad. To put it simply, it is to π the numbers of pi, that is, 3.1415926, to the harmonic minor scale, and compose it into a musical score, and play it. However, for reasons that are often used in piano music, only the number of decimal places can be accurate to 300 places. ”

Su Xi: "......"

You mathematicians, you're so boring!
