The bell of Jingyun Bell, perhaps everyone in the country has heard it, whenever the new year is welcomed, the melodious bell rings, sweeping away the old filth and ushering in the New Year.

The imitation Jingyun clock has also been hanging here for more than 20 years, and there was a time when the time would be struck every day.

These two bells are actually similar in appearance, and both the decoration and the inscription have been imitated as much as possible.

But there are some subtle differences.

For example, the imitation bell is two centimeters shorter than the original bell and weighs 500 pounds.

In fact, after so many years, the smelting technology has undergone earth-shaking changes, and the uniformity, impurity content, casting method, and tuning method of copper-tin alloy are completely different from those of thousands of years ago.

There are still a lot of changes that need to be made to make the tuning as similar as possible while ensuring that the appearance is as similar as possible.

Although the tuning of this bell is very close to the original bell, Gu Xiaobai has listened to the old version of the recording, and it is still obvious that the timbre of the two bells is still very different.

Moreover, for Gu Xiaobai, even the old version of the bell, which is known as the most beautiful bell, is still a little imperfect.

In Gu Xiaobai's mind, in the memory palace, in the "music room", the wall where the flute was once hung and was broken out by the system, the hole that looked like a dog hole, had been opened into a normal-sized door.

Through the door, you will see an open room with only three walls.

The room was empty and huge, and compared to the previous "music room", it was simply the difference between a bedroom and a factory.

The last wall, beyond the three walls, was a thin white mist, and behind the white mist, there were endless streamers flickering.

At this moment, that streamer was forming the scene that Gu Xiaobai saw in front of him.

This is the "MV" system that the system rewards Gu Xiaobai, as long as it is the time and space that Gu Xiaobai has experienced, it can be captured here as a picture.

At this moment, a streamer of light was extracted from the picture and turned into a model of a huge bell, suspended between the three walls.

There are three thousand weak waters, and I will only take one scoop.

Let it be endless in time and space, at this moment, for Gu Xiaobai, the most important thing is just this bell.

Countless nodes and numbers are marked on the model of the clock, and strings of characters emerge and then disappear.

In the mist, a ball of brilliant light poked out a head, looking at Gu Xiaobai coldly, a little unhappy in his eyes, and gritting his teeth.

Xiaobai, you used the system I sent you to do physics again, didn't you!

Why can't you be honest about music, you kid?

Believe it or not, Gu Xiaohei tore them all!

The system grinned at the clock, and then saw it vibrate suddenly.

The vibration starts from the lower edge of the clock, and at the moment of impact, the volumetric longitudinal wave begins to travel at a speed of 3.8 kilometers per second.

The body of the bell began to expand and compress, like a spring stretching and contracting, and it was rapidly transmitted along the body of the bell.

In the rear, the transverse wave is one step slower, propagating at a speed of 2.2 kilometers per second, making every particle in the clock swing from side to side.

Then, along the surface of the bell, the Rayleigh wave bends, propagates and chases the transverse and longitudinal waves in front of the surface of the bell at a speed of 1.8 kilometers per second.

Behind them, the vibrated air slowly spread and vibrated in all directions at a speed of 340 meters per second, like a supersonic fighter pulling out a trail cloud, like a dancer unfurling a snow-white long skirt, and like a peacock slowly unfolding its gorgeous long tail.

And countless formulas, numbers, and data are chasing behind this fluctuation, diffusion, change, annihilation, and integration......

All this only exists in Gu Xiaobai's mind.

Plane vibrations are maddeningly complex, let alone three-dimensional vibrations.

In reality, on the bell tower, in front of countless people, Gu Xiaobai took a step forward, and his two hands pressed on the two nodes of the bell.

There was a "buzz" and the bell changed.

Yes, for the vast majority of people, it's just the bell ringing.

Some discordant harmonics were suppressed at the moment when Gu Xiaobai's two hands were pressed, and the bell instantly became clear, just like the river after a flash flood, flowing through the rocky shallows, and all the impurities were filtered out.

The bell is clear, like the water of a sweet spring, refreshing people's hearts.

It seems to be able to cleanse all the complicated thoughts in the heart and lead people's hearts back to the prosperous era of the Tang Dynasty.

The staff in charge of ringing the bell, I don't know how many times he has struck this bell in his life, is dumbfounded at this time.

When he reacted, he couldn't wait to bump into it again.

"Knock~~Buzz~~~"

The bell rang again.

Any complex fluctuation, after being filtered by the human ear, which is probably the most amazing filter in the world, is just a combination of countless sine waves.

Therefore, there are thousands of vibrations in this world, which human beings cannot hear, just like such a wide spectrum, but human beings can only see a narrow part of it, called "visible light".

However, the human mind can be simulated without any limitation of time and space.

Thinking is the most gorgeous and beautiful existence in the world.

At this moment, everyone at the scene heard the wonderful bell, but no one could appreciate the beautiful picture in Gu Xiaobai's mind.

Only Deng Shunyang, who was standing next to him, was able to rely on his imagination to glimpse a trace of phantom.

This is the ment~that belongs to Gu Xiaobai alone

Above the bell tower, Gu Xiaobai withdrew his hand and said, "Try this ...... again."

He moved a place with both hands, and asked Jiang Wei next to him to add a hand.

"Boom~~Boom~~~~" The end of the bell became high-pitched.

"Jiang Wei, hug me......" Jiang Wei picked Gu Xiaobai up, and Gu Xiaobai stretched out his hand and pressed it somewhere on the upper part of the bell's body.

"Knock~~~Uh~~~~" The bell became thick and calm again.

Every timbre is so good.

On the bell tower, Gu Xiaobai and Jiang Wei pressed back and forth on the bell as if they were juggling.

Under the bell tower, tens of thousands of people raised their heads, looked at Gu Xiaobai on the high platform, and listened to the bell that kept ringing.

Next to him, several staff members frantically took pictures and videos, and took pictures of the position Gu Xiaobai held down every time.

I don't know what this principle is, but it definitely works!

And Gu Xiaobai, after striking the bell seven or eight times, took a few steps back with both hands: "No, I can't stand the numbness of my hands......

"Let me try?" next to him, Deng Shunyang was eager to try.

Several other veteran historians also looked excited.

Next to it, a sign is shining.

"Don't climb over the fence, don't touch, don't ......"

The staff struggled beside them.

Will you be fined later, and how much?
