After preparing the costumes, let the members of the Starlight Song and Dance Troupe continue to practice, while Xu Zheng dragged Forrester to study the magic array that matched the stage.

In addition to the instrument, this is the second most important thing, and it can't be done hastily like Iwaki, and after its own stage, it has to meet more requirements.

Xu Zheng and Forrester stayed together on the stage of the Cape of Watch, studying the handscroll left behind by the brilliant female mage of the City of Mages. The greatest achievement of this female mage was not to make the air more powerful, but to study its other uses in a different way, to completely transform this magic used for combat into an art, and to use it in a variety of ways. Before her, no scholar or mage had recognized that sound was transmitted through air, and this eminent female mage not only recognized this deeply, but also described and demonstrated it in detail in the manual, and gave many examples to support it. Xu Zheng and Forrester read it, and they both benefited a lot. Both of them are well-developed people, and every time they see an example, they will touch the analogy and derive more flexible ways to use it.

Four days later, Xu Zheng and Forrester were the main players, and Adam was the deputy, and the three of them began to make magic props and draw magic arrays. Now Adam has begun to study with Forrester, although he has not clarified the identity of master and apprentice, but Adam is studious, and Forrester is not stingy in imparting Adam's knowledge, Adam in the three Ruther brothers finally found his life's ambition, and he followed Forrester all day long, even if he was tired and tired, he smiled and squinted.

The magic circle was all in charge of Forrest, and Adam helped to do it. Xu Zheng designed three magic props and handed them to the gnomes and dwarves to make together.

In one day, the magic array was drawn, and Xu Zheng added a receiving part to the magic link of each magic array. This way it can receive magic fluctuations of the same frequency.

Three days later, three kinds of magic props were given by Lulu, and the samples were placed in Xu Zheng's hands.

Lana looked out. An octagonal thing the size of a palm, with a complicated magic array carved into it, and some small holes like honeycombs. One was a round thing the size of the tip of the middle finger, with a magic circle carved on the surface, and a circular hole in the middle. The last one is relatively large, a bit like the big horn that Chuck fooled out, but it is a duplex structure, with layers of large and small speakers nested together, a total of five layers. Their gaps can also be adjusted slightly.

"What is this?" everyone was asking, including Forrester, who only understood the magic array above, and the receiving formation that Xu Zheng had studied. There are motivational formations from outstanding female mages, oscillating formations made by himself, and amplification formations that work by absorbing the energy of the spar through the magic source, but when these are combined, he can't see what they are used for.

Xu Zheng smiled and picked up the octagonal thing and said, "This is called a magic microphone for the time being." He picked up the smallest one and said, "This one is called earbuds." Well, I still have to add the word magic. Magic earbuds. "Lift the big guy up again. smiled: "This, now it's not called the Universe Invincible Super Thunderbolt Loudspeaker, it has a more formal name, it's called the Megaphone." Belch...... Magic megaphone, because the principle is to work with magical energy. ”

Everyone was at a loss, they saw it, they heard it, but they just couldn't understand it.

Xu Zheng smiled and said, "Everyone knows." The magnitude of a person's voice is limited. I sang in Iwaki at the beginning. There wasn't a lot of space there, and everyone could hear clearly. But here it is now. Can you guarantee that your voice can reach every corner?"

Yi Meier shook her head, her volume was relatively louder than the others, and she didn't dare to say that she could ensure that everyone in every position could hear her when she sang hard.

Lana said, "This happens a lot when the elves perform at festivals. Many people gathered together, and the people on the periphery couldn't hear what was being sung inside at all, just joining in the fun. At this time, in order to let everyone hear more clearly, I can only sing hard. But as a result, firstly, the singer's voice will be greatly damaged after singing, and the light one will be hoarse for a while, and the heavy one will even be permanently damaged, my mother is like this, and then she can't sing well. The second point is the worst, because when singing too hard, it is very easy to lose the tune, and a good song is ruined beyond recognition! For a good singer, this is the most shocking. ”

Holding the three things in his hand, Lana, Xu Zheng said, "Let's try this now." ”

"How do you use it?" Lana watched curiously as Xu Zheng ran away, ran to the edge of the stage and put down the megaphone, and ran back to put the remaining two things into her hands.

Xu Zheng said: "Earbuds, as the name suggests, are of course used to stuff them into the ears. The microphone is a receiving device, and you can sing into it when you're ready. You don't have to put a lot of effort into it, use the volume with the best sound quality and the least effort when you usually sing. ”

Lana nodded, flipped over and over the ground in her hand, and studied for a long time before putting the earbuds in her ears. The elf girl is not stupid, she knows that the big head rushes outside, and the small head rushes inside......

The first time I plugged the earbuds, I felt a little uncomfortable, although it didn't hurt, but there was always a foreign body feeling. Lana shook her head, her long ears throbbing, and it took a while for Lana to stop.

"Alright. Xu Zheng said: "The elf itself can do magic, you can infuse a little magic into it to activate it, you don't have to exert a lot of energy, just wait for it to emit a green glow." People who don't have magic in other places can use hedrons, I removed the attribute absorption, the disadvantage is that it will waste some, and the advantage is not to be picky. ”

Lana, as Xu Zheng said, tried to pour some magic into it.

Sure enough, it was very effortless, and only a little magic was poured into it, and the octagonal microphone began to fluoresce slightly outward, and at first glance, it was quite cute.

Lana played with it a few times and said happily, "Is it okay?"

As soon as the words came out, I suddenly found that the loudspeaker over there also made the same sound, and the volume was much louder than that here, and it was also saying, "Is it okay?"

Lana was startled and exclaimed, "It's ringing!"

The megaphone said, "It's ringing!"

Xu Zheng laughed and said, "If there is a voice, it means that it has an effect." In this way, the sound can also be picked up, and the effect is okay. But it has to be strengthened, if it's too sensitive, I'm afraid that even the noise will be absorbed. Come on, Lana, sing a little song to it. ”

Lana timidly raised the microphone to her mouth and looked at Xu Zheng hesitantly.

Xu Zheng smiled: "Sing it, sing it how you usually sing it now, it won't bite." ”

Lana steadied herself and sang a little elven song with her voice outstretched.

The song she sang is called Elf Nocturne, which is about the feeling of an elf looking up at the starry sky at night, and the whole song lasts about three minutes, and the whole song is full of natural wind and yearning for nature and the starry sky.

As an elf, Lana's voice was originally quite beautiful, but at this time, the voice was not out of shape at all through the amplifier, and at the same time, the volume was expanded, and the thin part of Lana's voice was moistened a little bit, which sounded more perfect!

After singing the song, everyone applauded, Zan Lana's singing voice was beautiful, and Xu Zheng's production was completely successful!

After Lana finished singing, she took off her earbuds in surprise and joy, and said to Xu Zheng: "It seems that the sound is better, and it is easier to control the part of the melody change." This elven nocturne itself is not difficult to sing, but in order to sing it well, the smooth transition of the tune has always been very demanding, and it is necessary to try to imitate the changes in the night sky, which is usually quite exhausting, but this time it is easy. What's going on?"

Xu Zheng took the earbuds, found the smallest magic core and embedded it in the microphone for everyone to try, and finally explained: "Each of us makes a sound, and what we hear in other people's ears is different from what we hear." This is because we hear our own voices partly through the air, partly through the cheeks, and the skin of other parts of the body together to superimpose the effect, so there must be a distortion compared to the real sound heard by others. ”

"What do you mean by distortion?"

"Uh...... This, you can understand in this way, is the distortion of sound. Compared to the real sound, the part that is out of shape is called distortion. ”

Everyone nodded their heads to show that they understood.

Xu Zheng continued: "With the combination of earbuds and microphones, the earbuds receive the sound from the microphone and transmit it to the ears, which is much less distorted than the sound you usually hear. So it's going to make the voice easier to control, you see?"

Everyone nodded as if they didn't understand. In fact, this is an easy-to-understand truth in Xu Zheng's previous life, every singer will wear a headset when recording a song, just to ensure that the tone is not out of tune, and try to improve the original sound. But this truth is a bit advanced when it comes to the Aris space-time, where science and technology are not developed.

After listening to Xu Zheng's explanation, Lana couldn't put it down and looked at the earbuds and microphone in her hand, and said happily: "These two things are really good, they will make people's voices better." ”
