Chapter 155

Su Xi: "Teacher Gu, come out for dinner tonight!"

Gu Lu: "Tonight?"

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

Gu Lu pondered for a few seconds and then entered the message, "Okay, send me the time and place. I will 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 Chongwenmen in Yanjing, is a Western restaurant with a long history.

It is very famous in the catering field of Yanjing and has been consistently ranked among the top ten Western restaurants all year round.

But the price is not too expensive.

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

Su Xi had already reserved a seat in the restaurant.

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

Under the guidance of the waiter, Gu Lu met Su Xi who was sitting at the dining table with one hand on her chin and the other hand scrolling through her cell phone in boredom.

"You came so early?" Gu Lu smiled softly, took off his coat, and sat across from Su Xi.

"Ah, you're here." Hearing Gu Lu's voice, Su Xi raised her head in surprise, then answered Gu Lu's doubts with a smile, "Is it true that 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 different from them." Su Xi raised her hand and called the waiter, staring at Gu Lu with a pair of bright eyes, "I never keep the people I care about waiting."

Gu Lu coughed lightly and said, "Let's order."

As if something had happened, Su Xi picked up the menu and reported the names of the dishes, "Two musical steaks, two chocolate ice creams, one wild mushroom cream soup, one saffron prawns, and a bottle of white wine..."

"

Maxim's Restaurant specializes in French cuisine.

Moreover, the decoration of the restaurant is also in French romantic style, making it a very suitable place for couples to date.

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

A performer in a tuxedo plays romantic and melodious songs.

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

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

"Musical steak?" Gu Lu said softly.

Su Xi opened her mouth and explained to Gu Lu, "The steaks in this restaurant are made from Wagyu cattle. During the livestock raising process, special musicians will be invited to perform music. Through music, the cattle's body and mind will be more happy, so it is called musical steak."

"

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

"No, this will be more expensive!" Su Xi replied.

Gu Lu: "..."

Cut off a small piece of steak and put it into your mouth with a fork.

Gu Lu chewed and tasted it carefully.

really……

There is no taste difference from ordinary steak.

Gu Lu and Su Xi were chatting incessantly while eating.

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

At present, the five new stores are almost completely renovated. After this period of time, the stores will be opened, and Su Xi, the Yanjing regional manager, can relax.

"By the way, Gu Lu, what are you busy with during this time? Aren't university teachers' classes supposed to be very leisurely?" Su Xi looked at Gu Lu curiously.

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

Gu Lu explained with a smile, "I am busy with a topic, the second question of the minimal model program of birational geometry. I am currently stuck on how to prove whether the flip operation terminates after a finite number of times."

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

"You majored in finance, so it's normal that you don't understand these mathematical terms. Let me just say..." Gu Lv was just halfway through his words when he heard the melodious music in the restaurant suddenly stop.

Gu Lu looked at the piano placed in the center of the restaurant. A young man and the man in a tuxedo were talking quietly.

Then the man in the tuxedo stood 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 I dedicate "Dream of Love" to her!"

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

The customers in the western restaurant applauded cooperatively.

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

Then, melodious music sounded.

The young man is obviously an amateur piano player, and his playing skills are obviously not as good as that of the tuxedo just now.

But I still managed to play it completely with some stumbling.

The crowd applauded again with encouragement.

The young man bowed to everyone to express his gratitude, and then walked to the little girl.

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

then……

Then there are scenes that are not suitable for children.

Su Xi held her chin and looked at the young couple on the dining table with admiration, and sighed, "It's so romantic!"

"Teacher Gu, can you play the piano?" Su Xi stared at Gu Lu with bright eyes.

"A little bit more knowledgeable." Gu Lu looked Su Xi up and down and asked 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'm very good at playing the piano."

"I don't care."

"Besides, the style of piano music I know is a bit strange."

"It's okay." Su Xi said calmly, "Go up and play a song, Teacher Gu."

"Then I'll go?"

"Go, go, come on, I will applaud you."

Gu Lu stood up, straightened his clothes, and before the tuxedoed performer sat back down, he smiled apologetically and sat down in front of the piano.

The man in the tuxedo made a please gesture to Gu Lu.

The customers in the restaurant were quite surprised to see someone sitting in front of the piano again. This kind of incident was originally a small probability, but they didn't expect to encounter it twice in one day.

"A piano piece for my friend Su Xi."

Su Xi smiled sweetly.

She didn't dare to expect such difficult piano music as "For Alice". Even if Gu Lu played the simplest song "Happy Birthday", she would be extremely happy.

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

Miduofaduoshu...

Gu Lu played very smoothly.

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

The music wasn't bad, but... they just found it weird.

Many fragments are fragmented and have no sense of continuity.

It seems...this is not a piano piece.

Moreover, this piece of music does not feel familiar to anyone at all.

What is this song called?

Everyone was confused.

After the song ended, Gu Lu returned to Su Xi.

"What's the name of this piece?" Su Xi looked at Gu Lu with an inexplicable meaning on her face.

Gu Lu replied, "π"

"π?" Su Xi was a little confused.

Gu Lu nodded, with a serious tone on his face, "This is what a senior fellow abroad taught me. To put it simply, it is to map the numbers pi, π, which is 3.1415926, to the harmonic minor scale, and write it into musical notation.

And play it. However, due to the limitations of piano music, the number of digits after the decimal point can only be accurate to 300."

Su Xi: "..."
