Xu Yi stretched out his hand to catch it in confusion, and found that what Camilla Magician threw over was a square silver-white metal box with a side length of about twenty centimeters and a thickness of about five centimeters.

This metal box feels very light and thin, and it should be made of ultra-light rare earth alloys newly developed by the steel smelting center.

This new rare earth alloy is not only very lightweight, but also extremely hard, and also has very good magic penetration, if the magic circle is attached to this new rare earth alloy, the magic circle will exert a much better effect than attached to ordinary metal.

Now all kinds of magic machinery produced by the Xinfei Chamber of Commerce have begun to gradually use this new rare earth alloy to make the core part of the magic array, and all products are updated.

The new generation of bladeless adaptive variable speed magic fan that will be launched this summer is made of this rare earth alloy as the core power source of the magic array.

According to the measurement results of the Magic Research Institute, because of this change, the magic power output of the new magic fan has been increased by as much as seventeen percent, which is even much better than directly increasing the magic array as a power source by one level.

Because there are not many rare earth ores obtained from the Duchy of Mirando, and there are naturally not many rare earth alloys smelted and formed, so the Xinfei Chamber of Commerce is very careful with the use of this rare earth alloy, even stingy, except for the production of power source components, only a small amount is used to do some magic experiments.

As a special researcher of the Academy of Magic, Grand Magician Camilla has the privilege of using all kinds of research materials of the Academy of Magic at will, but of course he will not use them at will.

So...... What is this metal box for?

"Enter some magic and try it out. Grand Magician Camilla pointed to the metal box. Xiang Xu Yi smiled.

"Is this your latest magic machine?" Xu Yi wondered in his heart. Because no matter how you look at it, you can't see that it's a mechanical thing.

"Try it. Try it and find out. Grand Magician Camilla urged.

Xu Yi was a little speechless at Camilla's eldest magician's childlike expression, rolled his eyes, activated the magic power in his body, and injected it into the metal box.

Inside the box, as expected, the light of the magic array was stimulated.

However, to Xu Yi's surprise, the light that came out of the crack in the metal box was not the light of the four elemental magic, but a slightly strange light purple light.

When Xu Yizheng was stunned, a familiar voice suddenly came from the metal box.

Xu Yi...... Can you hear me? Hey, are you there? Xu Yi. Is Grandpa next to you?"

"Steele?!" Xu Yi was taken aback.

Although it is slightly different from his own voice, Xu Yi can easily hear that this voice is definitely Steele's.

Xu Yi glanced at the metal box in his hand in surprise, could this thing actually have a recording function? Can it record Steele's voice?

The next moment, however, he realized that he had guessed wrong.

Steele's voice rang out again in the metal box.

"Is that you, Xu Yi, I heard your voice. Are you with Grandpa? Grandpa gave you his magic call box, right?"

Xu Yi was stunned.

Could it be that this thing isn't recording, it's a real-time call with Steele?

Xu Yi settled down and replied to the metal box: "Yes, it's me." Steele, do you have a magic phone box in your hand, and you're talking to me in real time?"

"yes, how do you know?" said Steele's voice with some surprise. "Did Grandpa sue you?"

Xu Yi looked up at Grand Magician Camilla. I noticed that the expression on his face was a little surprised.

"No, Grandpa just gave me this thing. Are you still at home?"

"Hmm. I'm still at home. Akali was also nearby, and she brought the magic phone box and said she wanted to surprise me and you. There was a palpable joy in Steele's voice. "This thing is really good, even though I am at home, I can talk to you at any time, it's so convenient. ”

"Well, it's very convenient. But you sue Sù Akali for me, as a researcher at the Magic Research Institute, she has some research results, and she dares to hide it from me, the president, and I will deduct her bonus for this month. Xu Yidao.

"Why!" Steele just laughed, and immediately Akali's slightly nervous and unconvinced voice rang out. "President, this is Camilla's idea, he wants to hide it from you, and if you want to deduct the bonus, you must deduct him first!"

Xu Yi laughed: "I don't care, anyway, I will deduct your bonus this month!"

"I don't do it, I will ......"

Akali's voice stopped abruptly, but it was Xu Yi who cut off the magic input into the metal box.

Looking at the ordinary metal box in his hand, Xu Yi looked up at Grand Magician Camilla with a face full of surprise.

"Grandpa, how did you come up with the idea of researching this thing? What kind of magic array is used in it? Is there any hope for popularization? What is the maximum call distance of this thing? How many people can talk to at the same time? Can you talk to different people in different frequency bands? Can you set up a relay station and ...... with more?"

"Wait!" Grand Magician Camilla raised his hand and interrupted Xu Yi's question.

Frowning and glancing at Xu Yi up and down, Grand Magician Camilla asked with a puzzled expression, "I thought you would be surprised to see this new thing, but how did I find that you didn't seem to be surprised at all, and even seemed to be very familiar?

Xu Yi smiled, thinking that mobile phones have long been popular on the earth, and how could such a simple thing be just like a walkie-talkie, how could he be surprised.

But to be honest, he was indeed a little surprised, but what surprised him was not the magic phone box itself, but the fact that there was really a magic array that could achieve this effect.

If this thing could be expanded as he expected, wouldn't it be possible to build a mobile phone in this world as well?

Thinking of making a mobile phone in the magical world of Sainz Continent, the expression on Xu Yi's face couldn't help but be a little strange.

"No one told me in advance, but didn't you mention it to me before, saying that you want to get a magic machine that is convenient for conversation?" Xu Yi asked rhetorically.

"Is there one?" Grand Magician Camilla frowned and thought about it, but he couldn't remember that he had mentioned it to Xu Yi.

However, this is not an important issue, compared to the few issues that Xu Yi just mentioned, he is more concerned about.

"There's a small space circle in this. The main body of this circle is a teleportation circle, and after research, I changed it into a magic circle that only transmits sound through the guò space. Grand Magician Camilla said.

"Space Circle?" Xu Yi took a deep breath.

Space magic is a magic that can only be accessed and mastered after becoming a great mage, and even for a great mage, space magic is very difficult.

A great magician's mastery of space magic almost represents his own strength.

In space magic, the teleportation circle is an extremely difficult magic.

Prior to this, most of the magicians on the Sainz continent used this teleportation magic to establish a teleportation circle for human teleportation.

However, it is extremely difficult to build a complete teleportation circle, and it is also extremely difficult to maintain, so even in the entire Sainz continent, so far, only a few countries still have no more than twenty teleportation circles.

Even the Sky City, where the headquarters of the Wizards' Guild is located, only retains two teleportation circles.

It's not surprising that Grand Magician Camilla was able to master a teleportation circle, but it's amazing that he was able to modify the teleportation circle and transform it into a circle that only transmits sounds.

Xu Yi is not a great magician yet, and he can't master space magic, so he can't understand how Camilla is a great magician.

But that didn't stop him from understanding the difficulty.

Mobile phones on earth are able to make conversations, through the decoding and compression of sound through sophisticated mechanical and electronic instruments, and then through the guò radio communication signal to transmit, and finally on another mobile phone to convert into sound.

The complexity of this is self-evident.

On the earth, the birth of a mobile phone requires countless scientific research results and mechanical research technology as a foreshadowing, and here, the great magician Camilla actually transformed a magic array by himself and completed this research, which really made Xu Yi feel incredible.

Glancing at the metal box in his hand again, Xu Yi's heart suddenly moved.

"Grandpa, you're working with Akali on this research, right?"

"Well, so I asked Akali to send the other magic phone box to Steele, and I'll come to you. Grand Magician Camilla sighed, "Steele should be very happy to hear the voice, but you kid doesn't seem to be surprised, it's really disappointing to me." ”

Xu Yi smiled: "I was very surprised, but my surprise was different from Steele." Grandpa, since you're working with Akali, you should have used the magic array resonance technology that she is mainly researching, right? If I'm not mistaken, the magic array in the magic phone box in my hand and Steele should be the same, right?"

Grand Magician Camilla smiled slightly: "You kid is really smart. Yes, that's how this thing was designed. What? Do you have any comments?"

"I don't have a specific opinion for the time being, after all, I only found out about this thing today. Xu Yi shook his head and sighed lightly: "But grandpa...... You can't imagine what an impact this thing will have on the world. (To be continued......)
