quadruple sleep

The sudden situation shocked everyone present.

But it's scary. A layman can see the excitement, but only an insider can tell the truth.Bai Hao and the buddies beside him saw the clue and looked at the violin in horror.

Especially Bai Hao, his legs were weak and he staggered. If it weren't for the brothers behind him who helped him in time, he might have collapsed on the ground.

Hang Si's face didn't look very good.

Fang Sheng was an outsider and couldn't see why he was here. He was curious and asked, "What's wrong? What's wrong?"Why did a good string break?Was it broken by your friend?

Hang Si said calmly, "If the violin hadn't been removed in time, Bai Hao would have gone blind."

Fang Sheng took a breath and questioned, "It's common for violin strings to break. I've never heard of it hurting the eyes."

Hang Si nodded.

Yes, it is common for violin strings to break. The materials used are not up to standard, the strings have been left for too long, the tightness of a certain string has not been adjusted properly, or the strings have been used too many times, etc. open.

But if it breaks, it will break. The chance of hurting the eyes is very small. In addition, the material of the strings has certain requirements, so even if it is hit on the face, it will not hurt too much.Of course, this also has something to do with the degree and strength of the disconnection. Maybe even an inch of force can bleed, but under normal circumstances it will not cause serious consequences.

However, the situation of Bai Hao's piano is different. You can hear something fishy from the sound of the strings being disconnected. The force of the disconnection is quite strong, and the strings are stretched from the root, and the elasticity is very high.

It was all clear from Hang Si's perspective, which was why Bai Hao almost collapsed to the ground after realizing the seriousness of the problem.

Lu Nanshen carefully inspected Bai Hao's violin, turned to Bai Hao and said lightly, "The E string is broken."

Bai Hao murmured, "It's impossible, it's impossible..."

Some bystanders who were very close misunderstood Bai Hao's reaction and said, "That string is so thin, it's normal for it to break. Buy another one and replace it."

Bai Hao was still confused, and Lu Nanshen had no intention of explaining to the man.He took off the string from the piano and looked at it, "Come over and take a look. Are these the same strings you used before?"

There was something obviously wrong with Bai Hao's reaction. Even a layman, Fang Sheng, could tell that. The main reason was that she was the one who contacted Bai Hao these few times. Judging from the gifts Bai Hao gave to Hang Si, it seemed that his family background was good, so he should not be As others think, it is a string that feels distressed.

She asked Hang Si in a low voice.

Hang Si explained to her, "In fact, the most commonly broken violin string is the A string, because the A string is the most frequently used string in performance. On the contrary, the E string that Bai Hao broke now, although it is very thin, is As long as the quality is good and the method of use is correct, it will not be easy to break. Moreover, in order to prevent the E string from being embedded in the nut and being pinched off, a protective sticker is attached to the E string. Bai Hao has been playing violin since elementary school, and he is no longer a novice, so the E string broke. The possibility is very small.”

Fang Sheng suddenly realized what he said.

Nian Baixiao was nearby so he could hear clearly. He turned to look at Hang Si, slightly surprised, "You know your stuff."

"You're blind." Hang Si avoided the probing in his eyes without leaving any trace, and added lightly, "It's just superficial."

...Nian Baixiao understood it for a long time and asked Hang Si uncertainly, "Can the strings be made of fur?"

Fang Sheng couldn't help but cover his mouth and smiled.

Hang Si's mouth opened and closed, and he said slightly, "Well, sometimes fur can also be used as strings."

Let's see what happens.

But the strings of Bai Hao's piano must have nothing to do with fur. Even Hang Si felt that it was very possible that even Bai Hao didn't know what the strings were.

As expected, Bai Hao stepped forward and looked at the string. After reading it, he was horrified and pointed at the string, "No, this is not my string. The material is different!"

Several of his buddies came up and took a look, surprised.

Lu Nan glanced deeply at Bai Hao, "You don't even know if someone has moved your strings?"

Bai Hao's face turned red.

I really don't know.

Hang Si walked up to Lu Nanshen, took the strings and examined them carefully. He was a little surprised and said, "This material is very special."

There are only a few common types of violin strings, steel strings, nylon strings and gut strings.Different strings have different timbres. Among them, gut strings have a soft sound when broken, while steel wire strings are strong and bright in tone. The most widely used strings on the market are nylon strings, which have a long life, moderate tone, and are the most cost-effective.

Hang Si had never seen the string material in his hand. It seemed soft to the touch, but...

"Be careful." Lu Nanshen held her hand in time. She felt a headache on her fingers, but fortunately he dissuaded her in time and her fingers were not injured.

But the palms of his hands felt hot because of Lu Nanshen's actions.

Lu Nanshen carefully took the strings out of her hand, thought for a moment, and looked up at Bai Hao, "Want to try it?"

"What are you trying?" Bai Hao couldn't keep up with his thinking. He was still ashamed that he didn't realize it before the strings were changed.

Lu Nan saw that he was confused and didn't wait for him to react. He grabbed his hand and pressed his fingers on the strings, and then he saw blood.

Bai Hao was overjoyed and screamed a few times. One of the guys yelled at Lu Nanshen, "What are you going to do?"

Lu Nanshen ignored the man's yelling and said, "Let's put it in another place and bandage his wounds."
-
Ten minutes later, Bai Hao reached the second floor of the laboratory building with a finger wrapped tightly in gauze. Lu Nanshen, Hang Si and Nian Baixiao were already waiting there in the classroom at the end of the corridor.

When Bai Hao and his buddies arrived, many curious classmates also came and joined in the fun, but most of them were female classmates.

"Commander Xiao," Lu Nanshen smiled at Nian Baixiao, "Please do your best." That look and gesture were irresistible.

Nian Baixiao walked to the door and betrayed his appearance. Faced with all the kind words and advice from the female classmates, those who watched the excitement left in dismay.

Nian Baixiao turned to look at Fang Sheng, "Aren't you afraid?"

"What are you afraid of?" Fang Sheng didn't respond.

Nian Baixiao raised his chin towards the inside, "It may involve danger."

Fang Sheng didn't even think about it, "What's there to be afraid of?"

When Hang Si was taken away by Qiao Yuan, there was no news at all in the vast years. She had experienced such desperate and dangerous things.

Seeing Nian Bai Xiao looking at her, she immediately smiled and said sweetly to him, "With Senior Bai Xiao here, I'm not afraid of anything."

Nian Baixiao felt goosebumps rising again, but what should he say?

That's right, very useful.

"This material is more than enough for killing people."

After everyone sat down, Lu Nanshen placed the broken string on the experimental table and informed everyone.

Everyone was shocked, including Hang Si.

Bai Hao's voice trembled when she spoke, "Kill, kill?"

The buddies who came with him were also frightened and asked Bai Hao who he had offended recently.Bai Hao was about to cry but had no tears. Who could he offend? He was just a student, and his family was going well and he never heard of anyone seeking revenge.

"If I want to offend you, it can only be you." He looked at Lu Nanshen.

Lu Nanshen gave him a "you're boring" look and carefully picked up the strings.Hang Si, who was nearby, reminded softly, "Don't scratch your hands."

His hands are too precious.

Lu Nan looked at her deeply, his eyes as soft as doves, "Don't worry."

Bai Hao next to him felt sour when he saw this, and the concern and lack of concern were clear at a glance.

Lu Nanshen gently twisted the strings, "This material is sharper than steel strings, more flexible than sheep intestines, and looks very similar to nylon, so it can be confusing in appearance. In terms of timbre, it is very close to the timbre of nylon strings." , but there is a very small difference.”

Having said this, he looked up at Bai Hao and said lightly, "So it's normal that you can't notice or even hear the difference."

normal?

This sentence was simply a slap in Bai Hao's face.

Learning an instrument is inseparable from ear training. Anyone who plays an instrument well will also have good ears. Especially those who can learn the violin and do it well must have a very strong ability to distinguish sounds.Therefore, different strings have different timbres, which is not difficult for Bai Hao, who plays the violin all year round, to identify them.

But he really didn't hear the difference.

He subconsciously looked at the few friends around him. Although these friends were not violin players, their ears were quite strong. When they saw this, they all shook their heads.

Neither of them heard it.

Not to mention how ugly Bai Hao's face was. The fact that they didn't hear it can only mean two situations. One is that there is no difference at all, so it's normal not to hear it; the other is that there is a difference but not big as Lu Nanshen said, and they heard it. Not coming out.

The possibility of the former is almost zero. Different materials must have different timbres, but Bai Hao doesn't want to admit that the big boy in front of him has such strong ears.

"If this string hits you in the face, you won't just be blind." Lu Nanshen put down the string, with a smile on his lips, as if teasingly, "Bai Hao, no matter how you look at it, I am your savior."

Bai Hao really didn't want to admit this, but he had to admit it, so he had to say thank you to Lu Nan deeply.As for Lu Nanshen, he accepted this "thank you" very magnanimously.

"But why?" Bai Hao looked puzzled.

Why did this voice include so many questions, and why was it targeted at him?Why hurt him in this way?What is the purpose……

Lu Nanshen said nothing, looked at the other people, and asked about their musical instruments.

Several people were a little panicked when he heard this question, and they all said that it should be no problem.I'm not so sure, after all, Bai Hao's situation is right in front of me.

The keyboard, flute and cello are all there.

Lu Nanshen didn't touch the flute and asked the man to play the note first.The man thought Lu Nanshen didn't know how to play the flute and didn't take it seriously. He took the flute and played a few times.

But Hang Si knew very well that he didn't want to touch something that others had blown.

As soon as the flute sounded, it was normal at first. Unexpectedly, Hang Si's ears were covered by Lu Nanshen the next second.But even if she covered her ears, she still heard an extremely sharp tone.

She was horrified, her hearing was somewhat damaged and she could hear this sharp sound, but the others...

As soon as the idea came up, I saw everyone in the room covering their ears at the same time, including the classmate who played the flute. The flute fell to the ground with a bang. He staggered twice and fell to the ground. His face turned pale and something was wrong with him. He stood up suddenly. Rushed out of the classroom.
