Because this bell and drum harp is so special.

The Spring and Autumn Dynasty can cast its buttons, the Western Han Dynasty craftsmen cast its Yong, the Ming Zhongjun cast its soul, coupled with the modern mechanical design and manufacturing of the bracket and mechanical structure, and the generous donations of countless people.

...... in this world No other instrument has such a legendary experience.

It is like an artifact that travels through time and space, throughout more than 2,000 years of history, and there is no way to replicate or replace.

Gu Xiaobai doesn't want to, and he doesn't have the right to let it be named after a certain company or a certain person.

Refusing the title, it is also equivalent to losing a large part of the income, although everyone is very enthusiastic, but Gu Xiaobai has also been changing the design, since Dongcheng has given up the use of this design in the bell and drum tower, Gu Xiaobai naturally does not need to put so many bells, directly limited to such a narrow range, can expand its structure, obtain better acoustic effects, and carry out acoustic modification and addition.

The space is large, and it is also to hang a larger bell, because of the addition of the "Yongle Bell", the size of this bell immediately increased the volume of the entire "Bell and Drum Qin" design, but in addition to the "Yongle Bell", Gu Xiaobai also needs to cast other eleven bells, and these eleven bells are also enlarged in equal proportions, although they are not as big as the Yongle Bell, but the cost also begins to increase.

So the gap is still huge.

At this moment, suddenly several large donations appeared on the donation crowdfunding.

"Eritrean fans donate 3 million yuan ......"

"Sierra Leonean fans donate 5 million yuan ......"

"Ivory Coast fans donate 4.5 million yuan ......"

Seeing these foreign countries that suddenly appeared, let alone others, even Gu Xiaobai was stunned.

Is this a nation on earth?

Where are they?

Why do you donate money to me?

In the depths of the dark web, a certain little black compares scissorhands.

Ye~ Xiao Hei will always fight side by side with Xiao Bai!

Some underground black industries, underground banks, and money laundering agencies silently swallowed a mouthful of tears.

The literary and artistic circles and the business world are jubilant, chasing heat, fame and profit.

However, the attitude of the academic community towards this bell and drum harp is not clear.

In physics, acoustics, foundry, engineering, and mechanics, there are many voices of debate.

Many TV stations and talk shows on the Internet have invited experts from all walks of life to analyze the feasibility and technical difficulties of the "Bell and Drum Piano".

Some people talk eloquently, some people praise it, and some people scold it.

There has never been a unified truth in this world.

After rounds of popular science, even ordinary people understand how difficult this project is.

Most experts are in fact the same.

Gu Xiaobai's design itself is very innovative and theoretically feasible, but it is not theoretically feasible in this world, and it can be manufactured.

Of course, if Gu Xiaobai has this perseverance, perseverance and financial resources, as long as he continues to improve and run-in, he should be able to succeed in the end, but the cost and manufacturing difficulty may be much greater and higher than imagined.

Many people think that it will take about five or even ten years for this instrument to be made.

Deng Shunyang also accepted an interview with Dongcheng TV and appeared on the show.

In the show, he talked very sincerely:

On the one hand, Xiaobai has an unparalleled talent in acoustics, especially in music acoustics, and people who have never seen him can never understand how strong he is, and sometimes I feel that he is not human. It's only been a long time, and he's now the strongest in our school in this specialty. I can't find a second person like this in my lab, or in my school. But if there is such a project, we can cooperate in terms of professional knowledge and bring in talents. What is the most important thing? The most important thing is the funding, almost no one can get the funding, don't say we can't, you can't even be an academician, how much is this funding, let alone 100 million, a Tianyan only costs 700 million, right? You let a certain institution invest, it's impossible...... How many people can be funded by so much money? Twenty or thirty outstanding young people, this is ......."

"Now a lot of people are arguing about the significance of this, and some people are saying, "Why don't you donate so much money to the children in the mountains?" Whether you understand it or not, this thing is meaningful, whether it is culturally or scientifically, it has unparalleled significance. ”

"I think this is really a great cause, if there is anyone in this world who can complete this project, I think only Xiaobai, because he has so many fans who support him, this fan, really strong!"

"Yes, I donated money too...... I'm also a fan of Xiaobai, and a lot of us have donated money, more or less of a heart. ”

"I know a lot of teachers, and the children in the family take out the money to donate to Xiaobai, and we are all very supportive, because this is a good thing, Xiaobai has changed many people's view of star-chasing, including me, I used to think that star-chasing, what a low thing, hahahaha, yes, we are ...... age"

"I think Xiaobai can succeed, no matter whether there are twists and turns in the middle, he will definitely succeed, because he is this kind of person, and he will not give up if he doesn't succeed. ”

"I'm looking forward to the day when this may be the strongest instrument on the planet and finally come to life. ”

"This day is not too far away. ”

......

No matter how much hustle and bustle, Gu Xiaobai has been steady and steady.

The improved design drawings were handed over to the manufacturing company, and production and customization began in the factory.

Gu Xiaobai rented a factory inside Kechuang Future and started the initial construction.

The manufacture of those drums in the drum and piano, Gu Xiaobai directly handed over to Qin Chuan Musical Instruments to make them, Gu Xiaobai and Qin Chuan cooperated tacitly, and the progress was good.

Busy time always flies quickly, not to mention that Gu Xiaobai is busy in four eras at the same time.

Finally, 600 years ago, the Yongle Bell finally reached the final casting moment.

Dozens of furnaces lined up along four channels, surrounded by burning charcoal fires, kept warm as they could, while the furnaces were boiling with gold and copper.

In the pit, the inner and outer fan (the mold of the bell) is preheated at high temperature at the same time. Dozens of people operated a huge fan agitated, and dark smoke billowed out of the ground.

Hua Yan stood near the pouring mouth and glanced back at Gu Xiaobai, Gu Xiaobai nodded, and Hua Yan said loudly: "Start!"

Everyone immediately got busy, and the exits sealed by dozens of furnaces were opened, and the copper juice flowed and rolled freely.

Like boiling dragon blood, it flowed into the four pouring mouths and poured into Zhong Fan.

There is not the slightest blockage, there is not the slightest stickiness, there is not the slightest sign of condensation.

When the copper juice overflowed from the pouring mouth, Hua Yan shouted: "Stop!"

At that moment, he couldn't contain his excitement.

It's done!

It really happened!

What a hearty experience!

Now, it's just a matter of waiting for the results.

But in Hua Yan's heart, there was an unprecedented message.

After a few days, all the cooling was complete, the mound was dug up, and there was no artillery fire!

Gently knock on the outer fan, a smooth, bright, huge and incomparable bronze bell, sit quietly.

Gently tap the wooden stick in your hand and make a soft "buzz".

Although the interior was still stuffed with dirt, the sound could already be heard.

Transparent and majestic!

Like a dragon whispering!

Looking at the unprecedented miracle bell, Monk Daoyan was inexplicably surprised, broke free from the support of people, and stumbled forward.

At this moment, a "buzzing" sound was suddenly heard.

An invisible force lifted the bronze bell off the ground.

Monk Daoyan was shocked inexplicably, what was going on?

Could it be that this kind of spirit bell is not available in the world, and the heavenly bell is cast, and it is intended to break through the sky?!
