After Tianyou asked, the fairy took out a short golden rod from her body. Tianyou reached out to take it and was about to check it out. Unexpectedly, the fairy in the Secret Realm took out several metal parts, which were as many as a dozen pieces. Although it was just a handful of them together, the messy look really made people feel overwhelmed.

"this……"

"This is an item, unfortunately damaged in battle, and these are the parts of it."

Tianyou frowned and looked at the big handful of things in his hand, and then said, "It's no wonder no one is willing to help you repair it."

The fairy in the Secret Realm was obviously a little embarrassed, and quickly said, "I will pay you any compensation."

"I won't mention the reward for now." Tianyou didn't plan to help her for free, but... he looked at the fragments in his hands again. Tianyou said in advance: "I believe you have asked many people before. Now that this thing is like this, I can't guarantee that it will be able to be cultivated. I can only help you first. If it can be cultivated, let's talk about rewards. If I can't practice, please don't blame me."

This secret realm fairy was able to stand up for an irrelevant girl to stop Tianyou, the Zixiao Palace sect, which shows that her character is still very good. After hearing Tianyou's words, she did not feel any dissatisfied, but said seriously: "I asked you for help, so of course I can help you if I can. Even if I can't practice well, it's my luck. How can I blame fellow Taoists?"

Tianyou felt relieved when he heard this, so he walked to the workbench next to put the pile of pieces on it.

I have to say that this thing is indeed a bit serious. The dozen pieces I got before were not all. It should be said that these are just scattered parts, the real body, that piece of copper tube, and there are many complex constructions hidden in it. Tianyou's eyelids are thundering. Damn, I have never seen such a complex car transfer box.

First, turn on the spiritual light on the table to provide sufficient light source, and then take out the magnifying glass from the drawer. Tianyou carefully studied all the components, especially the main part, and the final result was - no results.

This thing is really too complicated. Just by looking at it this way, it is obviously not famous. Tianyou had no choice but to call Hu Niu and the others out to make dinner first, and then study it slowly after eating.

When I came back, Hu Niu and the others were practicing in the Cave Heaven and Blessings, so the fairy in the Secret Realm did not see it. Fortunately, she only thought they were in other rooms in the cave and did not think about it anywhere else. During the meal, the fairy in the Secret Realm also showed some surprise to Tianyou's group of demon pets, but she was just a little surprised, and she didn't react much.

While eating, Tianyou happened to chat with the fairy in the secret realm.

Although Tianyou knew before that the outer cultivators who could appear at the headquarters of Zixiao Palace were mostly not ordinary people, I really didn't expect that this secret realm fairy was actually a disciple of the head of Tianyin Sect. Although the secret realm fairy herself said that she was very modest, Tianyou thought that she was definitely an extraordinary person in Tianyin Sect. After all, she was a disciple of the head of the sect, so it would not be strange if she took over the next leader.

In addition to learning about the identity of the fairy in the secret realm during the chat, the most important thing is about this thing to be cultivated.

The Secret Realm Fairy always hides the function of this thing, and many things are unwilling to answer positively. It was not until Tianyou sincerely stated that if he did not understand the function and working principle of this thing, repair would be impossible. In desperation, the Secret Realm Fairy finally became a little straightforward, and Tianyou finally understood what this thing was.

Although the fairy in the Secret Realm still didn't say it directly, Tianyou has guessed it in general that this thing is mostly part of a controller, and its real function is "pronunciation".

This copper tube is said to be one of the pieces on a jade flute, and it is the most important pronunciation component. The body of the jade flute only functions as a resonator, and the real pronunciation is this small piece of copper tube. However, as a pronunciation component, this copper tube actually has a mechanical structure, and the internal gears are linked with various springs. It can drive internal mechanical movement by rotating the external structure and generate a series of linkages, and finally achieve the effect of changing the structure of the pronunciation unit to produce different sounds.

If it is just a simple mechanical linkage, Tianyou doesn't care much about it, but... this thing is actually a pronunciator. You should know that although it is easy to generate sound, it is extremely difficult to accurately control it. Think about the top audio systems on the earth that start tens of thousands or even millions, just for a simple pronunciation, but have almost the ultimate demands on the pronunciation unit itself.

By the same token, it is not difficult to restore this thing simply, but it must make the sound of the previous ones, and it must be fine, which is fatal. This not only involves the restoration of the structure, but also the shape of the resonance cavity, the strength of the material itself and the internal stress of the metal may affect the pronunciation and conduction of the material, and ultimately lead to changes in tone and tone.

Listening to the secret realm fairy telling the functions and needs of this thing, Tianyou felt that he would not be able to help him.

After a little consideration, Tianyou decided to tell the truth. Although he did not plan to help for free, Tianyou's main motivation for repairing this thing was to help, which was considered as a personal favor. Although the girl owed it, Tianyou felt that he wanted to save people, so he had to bear this favor. However, helping is one aspect. If this thing really cannot be cultivated, he cannot force it.

After weighing the pros and cons, Tianyou still said, "To be honest, I'm afraid that the fairy cannot be repaired."

“Why?”

Tianyou sorted out the language a little, and then briefly explained some principles involving sound production. I originally thought it would be very difficult to let the other party understand, but unexpectedly, the fairy in the secret realm seemed to have a certain understanding of the principle of sound. Although her understanding is similar to traditional Chinese medicine's understanding of the human body and is a kind of cognition based on experience, it has to be said that it is indeed quite reliable. As long as Tianyou speaks a certain theory, she can immediately understand it based on the actual situation.

With this understanding, it is really much easier to communicate.

After listening for a long time, the fairy in the Secret Realm who finally fully understood Tianyou's meaning asked: "In other words, you may be able to repair it, but after repairing it, will the sound it makes be different from before?"

Tianyou nodded and said, "That's true. Moreover, if I don't practice, the fairy can try to find someone who understands the rhythm to help you repair it. But if I repair it, if there is any mistake in the thing, it will completely change the structure of this thing. I'm afraid I can't practice it even if I want to."

Tianyou This is not an exaggeration. It's like an iron bar, and you will make a sound when you knock it, but if you break it and then weld it again. Because there is a welding point in the middle, its internal structure changes, and the silver color will inevitably change. Perhaps this change is small, but you can't deny it exists.
