If the shadow stone in the Great Elder's hand was just a display of some inconsequential images, it might not be enough to shock the iron stone to the point of losing his voice. But those images ...... It should have been recorded by the shadow stone in the dragon king's hand.

It's definitely not just a coincidence!

Iron Stone knew very well that the reason why all this happened must be because of the wire! As for why that wire made this happen, Iron Stone didn't know, and he didn't want to know. Iron Rock only wants to know one thing now, are these images real?!

"Master, this ...... These...... Is it all true?" Iron Rock asked, pointing to the scene in the stereoscopic image.

"Nature is true. He was adamant.

"Hiss......" Tie Yan took a deep breath when he heard this, and was silent for a long time before he said, "I understand! If that's the case, then as long as there are one or two walkie-talkies, and two of them are connected by a long enough wire, even if they are two people thousands of miles apart, they can sit face to face and talk and chat!"

"No, you don't need any wires long enough to allow two people who are thousands of miles apart to talk and communicate face to face!" He Wei said with a smile and denied the iron stone.

"Don't use wires?" hiss...... Is it, young master, do you want to ......!" Thinking of a possibility, Tie Yan took a deep breath and looked at He Wei with a look of horror.

At first, after listening to He Wei's words, Tie Yan felt a little puzzled, and didn't understand why He Wu said that he didn't need the wire used to connect the two Gramogram Stones.

However, when Tie Yan saw the confident smile on He You's face, Tie Yan suddenly realized that it was possible! No wires are needed, even if they are thousands of miles apart, they can also let the other party hear their voices, which He Wei has already done with a walkie-talkie!

Since He Wei has used the walkie-talkie to make two people thousands of miles apart hear each other's voices without connecting anything, does that also mean ......

"Xiao Jiu has already calculated, the reason why there is that kind of resonance between the two lingering stones used in the first test, and there is that kind of magical situation, is actually because the lingering stones are recording ......" He Wei explained to him that Xiao Jiu explained to him before, after adding a wire between the two lingering stones, the reason why the situation similar to signal transmission was produced was explained to Tie Yan in detail, and he didn't care if Tie Tong could understand it at all......

"Therefore, since we know that the images recorded by the Lingering Stone are actually a kind of sound wave-like fluctuation with a specific frequency, then we can use the same method as transmitting sound signals, converting them into electromagnetic wave signals, and then transmitting signals over long distances or even ultra-long distances through signal transmitting and receiving devices. ”

"In this way, we can communicate wirelessly even if the two sides are thousands of miles apart, just like using a walkie-talkie!"

Facts have proved once again that when He Wei said this to Tie Yan, he was completely playing the piano to the cow! He Rory said so much, but Tie Yan really understood only one sentence," ...... Even if you are thousands of miles apart, you can communicate wirelessly like a walkie-talkie......"

Sure enough, this kind of thing can really be used like a walkie-talkie, without the wire, and also "normally" when thousands of miles away.

"Of course, the size of the information flow required to deliver video and audio information is obviously different. If we only use the signal transceiver used on the walkie-talkie to send and receive signals, the quality of the video call will definitely not be guaranteed. Therefore, we need to make several high-power signal transceiver ......"

"Young master, young master, you listen to me......" Tie Tuo interrupted He Wei's words with a painful face, and then said softly, "What's that...... I don't understand what you're saying, so ...... Otherwise, don't talk about it, just tell me what to do!"

"Huh, don't you understand, don't you understand at all?" He asked worriedly.

"Well, I don't understand at all. Tie Tuo replied.

"That'...... Okay. He said helplessly, "Here are a few design drawings, you can take a look at them first." ”

As soon as He Wei's words fell, Xiao Jiu immediately released the design drawings that had been prepared a long time ago, and said: "Tietuo, these are a few parts that I need you to make, you look at the drawings first, if there is anything you don't understand, you bring it up, let's discuss it." ”

"Hey, what's there to discuss?" Tie Tuo said, "Where do I need to mix in the design drawings made by Miss Xiaojiu......?"

"Let's discuss it, this time it's different. The things in the previous design drawings are all things that have been verified and I know very well with the young master, so under normal circumstances, there will be no big problems with the design drawings. Xiao Jiu said, "However, this time the videophone is different. This thing was designed on a whim of our own, and there was no finished product or similar technology to refer to before. Moreover, the young master and I don't really know much about the Shadow Stone, so there will definitely be a lot of problems in this design, and these problems not only need to be solved, but we need to discover them one by one!"

"Huh, you mean...... What do you mean...... You don't really know if this design fits?" Tie Tuo asked with a look of disbelief.

"It's not that I don't know if it's going to work, but it's certain that it won't work. Xiao Jiu said, "We need to take one step at a time this time, try little by little, learn from our failures, and constantly improve the design until we make the video phone." ”

Once upon a time, Tietuo was just an ordinary blacksmith shop owner in Chiyang City, and although his skills were good, if he could surpass his peers, it would not be enough. Later, I met He Wei and helped He Wei make bicycles, hang gliders, hot air balloons and many other strange things. Yes, at the beginning, Tie Tuo felt this way in his heart, this guest's request was too strange, and the thing he asked to do was too strange.

But later, an iron tuo who was originally just an ordinary blacksmith shop owner, with his craftsmanship that was not much higher than his peers, made one shocking thing after another, and these things were all made by He Wei. And at that time, he was just doing exactly what He Wei told him......
