The research on piano has reached its final stage, but it has been unable to succeed due to material problems, so Jiang Xingchen placed all his hopes on the cold iron.

In early December, when the Han Tie was transported back, Jiang Xingchen was ecstatic and immediately sent the Han Tie to the workshop for wire drawing.

Cold iron is a natural ore and contains few impurities and can be melted directly. Soon the workshop made a batch of cold iron wire and sent it to the research institute.

However, Jiang Xingchen was full of hope, but the result was a basin of cold water topping. The cold iron wire was good, but the sound quality of the test was not much different from other materials.

"How could this happen? Can't you really find other materials to replace copper wire?" Jiang Xingchen frowned and murmured, feeling very depressed. He thought that it would be difficult to make a piano, but he didn't expect it would be so difficult.

.

He has been in this world for more than three years and has never seen copper, or it should be said that he has never seen copper like that on earth. Although the copper coins here are also called copper, they are a completely different metal.

The yellow silver looks similar to copper, but it is not like copper on the earth.

In addition to iron, many metals here are different from the earth. Purple gold, cold iron, and yellow silver are not found on the earth, and even limestone is not common... At the beginning, everything in this world was still felt

It is similar to the earth, but the deeper you get in touch, the more differences you will find.

"If I had known this, I wouldn't have spoken in the monthly magazine at the beginning..." Jiang Xingchen was also a little anxious now. If he could not study the piano this month, he would be criticized for being a little bit. The fans of Zijing would definitely be very disappointed. This is him

The last thing I want to see.

"Hey! Let's teach you a lesson!" Jiang Xingchen sighed. With the help of the formation for the past three years, he has been smooth sailing. He didn't even notice that he was a little fluttering. In the past, he would never do anything but say something without confidence.

Such a thing.

Shaking his head, Jiang Xingchen felt his mind a little confused and walked out.

When Xianning saw Jiang Xingchen's appearance, she wanted to stop him from persuading him, but Wanrou grabbed her and whispered: "Let him calm down, let's go find him later!"

Jiang Xingchen left the institute and walked aimlessly. He stepped on the snow under his feet and made a creaking sound, which seemed extremely harsh in the empty and cold environment.

Before he knew it, Jiang Xingchen walked to the top of the back mountain and stopped.

"Hu~" He let out a breath, Jiang Xingchen looked around and couldn't help but recall the first time he entered the vast mountains. It was in this place that Mei'er waited for herself in the scorching sun for several days in a row.

.

When I think of Mei'er, Jiang Xingchen's longing was like a fountain, erupting suddenly from the bottom of his heart, and he could no longer suppress it. He even wanted to go to the Yueying Kingdom... From the construction of the new town last year to the present, he had almost no

I was very tired after being idle. What he wanted most now was to close his eyes and let Mei'er press his head.

"Click!" A sudden sound came from beside him. Jiang Xingchen immediately woke up and turned his head to see that it was a big pine tower.

"Where did this thing come from?" Jiang Xingchen looked up and looked up, and couldn't help but be slightly stunned, then smiled.

Just on the branch of a pine tree in front of him, Nier's pet pomrose was squeaking at him, her big black eyes blinked, and a big pine tower was also supported on her small paws.

After shouting twice, the little pompoon raised its claws and threw it over. Jiang Xingchen raised his hand to catch it, and said with a smile: "You little thing, you are looking for food yourself, do you still ask me to help?"

"Squeak!" The small pomrose jumped on the branches, then quickly jumped up, and there was a large pine tower on the fine branches on the top of the tree.

Jiang Xingchen looked at the movement of the little pomrose and said to himself: "What kind of velvet rat, I think it's a squirrel..."

Jiang Xingchen was thinking that the small pomrose had already reached the top. Perhaps because the branches were too thin, the small pomrose was hesitant, so he looked around, and then his big tail wrapped around a thick branch, and then his whole body stretched out.

.

"Oh!" Jiang Xingchen's eyes widened. The little guy actually used the power of his tail to provoke his entire body. It was so amazing.

"Squeak!" He picked the big pine tower, and the small pomrose screamed twice excitedly, then jumped back to the thick branches, throwing the pine tower to Jiang Xingchen.

At this moment, Jiang Xingchen was suddenly stunned and did not reach out to pick it up. The pine tower fell to the ground.

"Squeak!" Little Pomel was very dissatisfied and jumped on the branches and shouted.

Jiang Xingchen seemed to have not seen it, and was still stunned, and then suddenly shouted: "I understand, it turns out that I was wrong from the beginning!"

Before he finished speaking, Jiang Xingchen turned his head and ran back. The little pomrose looked at Jiang Xingchen running away, and there was a word of confusion in his big eyes.

Jiang Xingchen returned to the research institute and went straight into the house and started to do it. The moment the small pompoon's tail was rolled around the branches, he suddenly remembered that the copper wire seemed to be thread-shaped. In his previous life, he took a quick glance on the Internet and saw

It was copper, and I always thought it was copper wire, but the small ball of pompon reminded him.

This memory made him feel like a flash of lightning flashed through his mind, piano, piano. Is it not that the piano used for copper wire, but steel wire, and the copper wire is wrapped around the steel wire!

Therefore, Jiang Xingchen could no longer stay and ran back to the research institute immediately.

The strings were still using cold iron, but he tried to wrap the original yellow silver wire around the cold iron wire. When he tried again, the tone changed and the voice was very low.

"It turns out that the copper wire is just responsible for the bass!" Jiang Xingchen slapped his head hard, why didn't he expect it?

Continuing the test, Jiang Xingchen found that the sound quality of Han Tie was still not good. However, at this time he did not think it was a problem with the materials, it was a problem with the manufacturing process.

The steel wires of the previous life were not capable of completing the strength and tensile level of this world's craftsmanship.

However, the strength and stretching of cold iron are stronger than steel. Although it is impossible to make alloys or something, there is no problem adding monster bones. His folding crossbow is to add monster bones and the strength of the bowstrings.

And the stretch are very high.

"Fortunately, only one leg bone was sold at the auction, and most of it was left!" Jiang Xingchen was glad in his heart and immediately ordered someone to send all the monster bones to the workshop, and at the same time he called the old man over. He wanted to melt the monster bones.

, one must rely on the old man's profound cultivation to stimulate greater firepower.

Wanrou Xianning looked at the busy Jiang Xingchen and showed concern. Although Jiang Xingchen had a new discovery, what if it was not successful? Xianning had been doing research and knew very well.

The blow is very uncomfortable.

It can be said that they were all holding their hearts until the newly designed string test. Until three days later...

"Success!" A cheer broke out in the institute. Jiang Xingchen breathed a long breath and sat on the chair, with a smile on his face.

"It's successful, finally it's successful!" Xian Ning and Wan Rou were extremely excited and almost cried with joy. The design of this piano was too difficult, with the structure, procedures, materials, parts, etc. so complex that it was indescribable.

Xianning is sure that this piano is much more difficult than any invention he has studied and designed.

At this time, the two women finally let go of their worries about Jiang Xingchen. Xianning looked at Jiang Xingchen with admiration.

The craftsmen were also excited and cheered and howled. The piano had tortured them for too long. For a while, they even thought that the thing Jiang Xingchen had come up with was simply impossible to achieve.

But now, when these craftsmen were so excited that they could not do anything to themselves when they thought of the first King of Musical Instruments.

Only the old man kept sucking his lips and sucking his teeth. These strings were made of cold iron and level 25 monster bones. Any one he took out would probably be worth hundreds of thousands. What is this?

Musical instruments are too expensive.

After a long time, Jiang Xingchen waved his hand and asked everyone to stop. Now it's just that the strings meet the requirements, and there is still a lot of work to be done later. These strings are definitely not enough, thick, thin, and so on.

There are many things, and this can only be determined when tuning. In addition, you need to choose materials for the soundboard to see which wood is more suitable.

Afterwards, everyone in the institute became busy again, and the craftsmen were all enthusiastic and the work they did was more beautiful.

Xianning leader made string strikers, three-layer lever connection system, and pedals. Craftsmen built shells and some parts. Wanrou and Jiang Xingchen were responsible for tuning, and some adjustments such as sound codes.

Where in the iron smelting workshop, cold iron and monster bones are consumed in large quantities, making a large number of silk threads of different thicknesses.

The old man looked at the decreasing monster bones, and it hurt. So many silk threads could not be used all, most of them were used for experiments... It would be great if these were made into folded crossbows, that kid still had a piece in his hand

There are thousands of pounds of purple gold and hundreds of folded crossbows, which makes people frightened to think about it!

On the afternoon of December 15th, the institute burst into cheers again, and the piano finally succeeded.

"So beautiful!" The huge white grand piano was placed in the room, and everyone exclaimed. The pride in the hearts of the craftsmen was suddenly aroused. This is the king of musical instruments. Just by saying the cost, it can scare people to death.

When it comes to how much materials and how much labor is used, those monster bones are worth at least tens of millions.

"Xingchen, don't you show us the beautiful and beautiful sound of the King of Musical Instruments?" Wanrou asked suddenly.

When she said this, everyone's eyes were gathered on Jiang Xingchen, with an expectant look on her face.

Jiang Xingchen shook his head and smiled, "I'm not skilled now, I must be familiar with it for a while!"

This time, Jiang Xingchen dared not be too big. The piano has seven or eighty-degree ranges and eighty-eight buttons. Even if Jiang Xingchen has a formation on his body, he is sensitive to waves and his fingers are extremely flexible, and he will need to be familiar with it for a while.

In addition, he had to prepare some classic piano repertoire for the celebration performance.

As Jiang Xingchen was fully committed to piano production, the outside world's doubts about the celebration were getting louder and louder. Many fans of Zijing couldn't help it and all rushed to Xingchen Collector! (To be continued in advance)
