Dreaming about the world, embarking on the path of spiritual practice

Chapter 58 Lullaby

……

Wucheng is a place where caravans can rest. Although it is not large, it is very prosperous.

After entering Wucheng, he was dazzled by the prosperous business scene in front of him.

Yu Liang first found an inn as a place to stay, and then wandered around the city.

Unlike the Central Plains, everything here is mixed with alien customs.

There are many strange and strange products on display in the shops and stalls on both sides of the road.

Unknown colored minerals, plants with strange fragrances, handicrafts with strange shapes...

There are also some Hu merchants who deliberately let dancers stand aside to perform in order to attract the attention of customers.

They were dressed in strange clothes, exposing their limbs, navels, and half-stretched buttocks, and danced with coquettish figures, shockingly attracting passing businessmen from the Central Plains.

Yu Liang was not surprised by these. He had seen hotter scenes in modern times.

I am very interested in browsing those gadgets from the Western Regions that are rare in the Central Plains.

Just like this pagoda-shaped music box in front of you!

The whole body is carved from a special kind of bluestone, and the tower body has seven floors.

Every time a layer rotates, a crisp sound will be emitted from its interior.

From the first floor to the seventh floor, the sound produced is exactly seven tones from low to high.

The pagoda-shaped music box also has a chassis. As long as you put it on top and twist the knob underneath, the seven-story tower will automatically rotate, and the sounds will be connected together to play an exotic piece of music.

“Friend, if you like it, buy it!”

"Let me tell you, this is a treasure. Its name is 'Linglong Pagoda'. I spent a lot of money to buy it from a master!"

"If you listen to it at night, it will help you sleep. You will feel very energetic and refreshed in the morning!"

The Hu businessman in front of me speaks semi-fluent Chinese and strongly recommends his products.

Yu Liang knew that this thing was just a rotating sound box.

What interested him was not the thing but the music it could produce.

He has extensive research on both sound therapy and hypnosis. When he heard this music, he immediately felt its value!
From Yu Liang's feeling after listening to the music and Hu Shang's description, he could tell!

The frequency emitted by this music should be very similar to the frequency of brain waves when people are in deep sleep.

Therefore, listening to it while sleeping can relieve mental stress, help you sleep, and make people sleep particularly sweetly!

If you listen to it while sleeping for many years, it will be of great benefit to your body.

"How much do you want this thing?"

Seeing Yu Liang asking about the price, Hu Shang smiled and held up a finger: "It's not expensive, only ten taels of gold!"

"Ten taels of gold? Too expensive, too expensive!"

"This is a thing that can make noise, how can it be worth ten taels of gold?
I'll make a price, and if you sincerely want to sell it, I'll buy it. If you don't sell it, I'll turn around and leave! "

"Then tell me first!"

Yu Liang stretched out five fingers: "Five taels of gold!"

Hearing this, Hu Shang shook his head crazily and said: "No, no, no, this is too low. This is a treasure of mine. Five taels of gold is not enough. The minimum is nine taels."

Yu Liang still held out five fingers: "Five taels!"

"No, it's too little, at least eight taels!"

"Five taels!"

"..."

After pulling each other for a few more rounds,

Finally, Hu Shang offered a price: "At least seven taels, otherwise I won't sell it!"

Seeing that the fire was almost done, Yu Liang immediately stretched out six fingers: "I only have six taels, not one more point. If you sell it, I will take it. If you don't sell it, I can't afford it!"

Hearing what he said, Hu Shang lowered his head and counted his fingers, and finally gritted his teeth and nodded: "Okay, I'll sell you six taels of gold!"

Seeing that the other party agreed, Yu Liang smiled on his face. "My money is in the inn. Are you going to get it with me, or are you waiting here for me to get it?"

"I will go with you!"

Hu Shang put the sound box into a wooden box and followed Yu Liang to the inn where he stayed.

Entering the room, Yu Liang took out 60 taels of silver from the package.

Seeing the silver in front of him, Hu Shang immediately shook his head excitedly and said, "No, no, no, I don't want silver, I just want gold!"

"Silver and gold are the same!"

"No, no, no, it's different!"

Seeing that he still couldn't stop shaking his head, Yu Liang curled his lips and said, "Anyway, I only have silver, not gold."

"Otherwise, I'll give you two more taels of silver, and you can just find someone to exchange the silver for gold."

After hearing this, Hu Shang lowered his head and thought for a moment, and finally agreed.

Pay in one hand and deliver in one hand.

After Hu Shang left, Yu Liang closed the door tightly and listened to the music from the music box over and over again.

After feeling that he had almost learned it, Yu Liang went to the city to buy a piano and came back and imitated playing it.

The clank sound of the piano sounded, and the tone and melody were exactly the same, but it had no effect at all.

"What's the difference? The pitch and melody are the same, so the frequency should be the same!"

"Is it because the instruments are different!"

In order to explore the reason, Yu Liang dismantled the music box.

With his years of skills in repairing mobile phones, it was quite easy to dismantle this thing.

After all the parts were neatly placed on the table, Yu Liang discovered that although this thing had many parts, its internal structure was actually very simple.

Just like a modern music box, there is a stone pillar in the middle with some regular concave and convex points distributed on the stone pillar.

On each floor of the tower, a copper piece of different widths protrudes.

When the tower body rotates, the concave and convex points on the stone pillars will form copper pieces that move regularly, thus making different sounds.

The chassis is simple, it just needs a clockwork turntable!

"Huh? What is this?"

When Yu Liang touched the inner wall of the tower with his fingers, he felt a slight unevenness.

After careful observation, I discovered that the inner wall of the tower appeared to be smooth, but in fact there was a layer of tiny circular patterns that were not easily noticeable if you were not paying attention.

"It's really ingenious!"

After some research, Yu Liang came up with the reason why the music he played on the piano had no effect:
The concave and convex points of the stone pillars cause the copper plates to vibrate and produce sound. The sound waves reverberate within the tower body and are affected by these lines, thus changing their frequency.

After the research, Yu Liang wanted to restore Linglong Tower, but found that he could not restore it.

I'll go, it's over now!

Every disassembly step is clearly remembered in my mind, but I want to reload it according to the steps, but I find that I can't reload it.

Disassemble the assembled parts and arrange them again.

Recall good ideas and reassemble step by step!

"No, it's not right here. The structure here is different from when I demolished it!"

Yu Liang discovered the reason why the assembly could not be put back together.

"How could this be?"

Yu Liang was helpless with the parts in his hand, so he had to put them away and store them.

"Yeah, 62 taels of silver are wasted!"
