To be honest, although it was surprising to see Carmier appear outside the windowsill, after seeing the other party's azure blue arcane light, Gao Wen guessed that the achievements of this ancient great magician were probably extraordinary, otherwise he would not have lost his composure: Carmier was always a very steady person, but he would only change his personality when it came to his research projects. He once heard technicians from the Rune Research Institute and the Magic Technology Institute discuss Carmier's state at work. Sometimes he encountered inspiring results. This ancient magician even changed color like a neon light...

Of course, the technicians in the institute didn't know what the neon light was. When they saw Carmier playing lighting effects in the laboratory for the first time, they thought the master was going to explode...

"What did you make?" Gao Wen did not make polite to Carmier, and directly communicated with the other party in front of the windowsill. "Have you finally summarized the changes in the magic field?"

"Ah...that's not," Carmier's bright blue arcane light flashed slightly, and then it became brighter again, "but that's still an exciting result. Please come with me. The equipment is still in the institute for the time being."

Gao Wen saw that Carmier wanted to keep him in a silence, but he happily cooperated and turned his head and called Hetty: "Come on too, let's see what Carmier made."

The three of them immediately left the lord's mansion and came to a laboratory located in the Magic Technology Institute.

Carmier was originally a member of the Rune Research Institute, but this ancient magician who was knowledgeable and involved in the disobedient plan was not only capable of theoretical knowledge, but also had extraordinary talents in various practical technology fields. After getting in touch with and quickly familiar with the various technologies of the magic industry, he also established a laboratory led by him in the Magic Technology Research Institute, which specializes in the practical technology field, specializing in various practical technologies, and transferred some projects here.

In this neat and bright laboratory, Gao Wen saw a large number of things that were in semi-finished or dismantled state, including magic obelisks, orbital acceleration devices, new generation magic capacitors, etc., which were all placed in various experimental areas in different categories, but these were obviously not the exciting results that Carmier said. The results were placed on a platform in the center of the laboratory, and their appearance... were unprecedented.

Gawain saw a triangle base. This shape is a design commonly used by many magic devices in the ancient Gondor Empire. Kamier is also used to using this style in many of his creations. The upper triangle base is made of common copper substrates, which may also be mixed with traces of crystal dust or crystal blue steel, which makes it appear a beautiful and mysterious blue-purple color. In the middle of the base, the main body of the device is raised upwards and a piece of crystal clear artificial crystal is embedded. The crystal has a pure texture, but the color is almost transparent. This shows that it is not an overly expensive magic material, but should be just the real mystery of an ordinary magic release medium device, most of which is hidden in the triangle base.

The entire device is not large in size, with the longest side only about half a meter. The design of the ancient Gondor Empire makes it present a perfect symmetrical effect. Coupled with the metal support raised in the center and the crystal, it is even more like a decorative work of art when placed on the laboratory bench.

"It can be revealed now," Gao Wen looked at the things on the laboratory bench with great interest, vaguely guessing its possible effect in his heart, "What is this?"

"Please wait, I'll activate it now. If another device is also functioning properly, you should be able to see it soon..."

Carmire said as he floated to the device and activated the base of the device with a small spark of energy.

Accompanied by an extremely slight buzzing sound, the beautiful device started to run, and the runes on its base lit up one by one, while the crystal inlaid in the center was filled with a slight white light. After a moment, the air above the crystal began to twist and shake, and a vague image appeared in front of Gao Wen during the shaking.

Gao Wen's breathing could not help but speed up, and even Hedy next to him couldn't help but take a light breath.

The picture finally stabilized. Gao Wen saw his eternal vitality granddaughter shaking his head around the screen, as if he was operating or observing something around a device opposite. She fiddled for a few seconds before she suddenly saw Gao Wen. She waved her hands excitedly, and a clear and cheerful voice came from the base of the device: "Ancestors!! Look at what we made!!"

"I saw it, I saw it!" Gao Wen said excitedly, and he rarely had moments of emotional changes so obviously and so excited in order to maintain his ancestor's majesty, but at this moment he really couldn't control himself because he knew too well what Carmier and Rebecca meant. "You finally succeeded! Rebecca, where are you now? How far is the communication distance?"

"I'm in the North Shore Development Zone!" Rebecca said happily, then dodged away. Gao Wen then saw a large open view outside the window in the projection. It was the foundation that had just been leveled out of the North Shore Development Zone. "This is still very clear here! Can you see me clearly? Can you see me clearly? Can I see you clearly! Ah! I also saw Aunt Hedy! Aunt, you are really drawing dark circles today!"

"Calm down, this kid has always been like this," Gao Wen pressed Hetty's shoulder casually, "You really have the dark circles of your eyes?"

"Of course not!" Herty was a little crazy. She could never understand how Rebecca could turn the topic into a strange direction under any circumstances. Even if the silly roe deer was raised by her, she couldn't understand. "I'm really...but you actually got this thing out!"

Although she was full of the idea of ​​beating Rebecca, the meaningful device in front of her finally attracted Hetty's attention. She surrounded the device several times, trying to judge the magic principle and the difficulty of manufacturing. But in fact, she already knew the answer: if this device was made by a traditional messaging spell model, then Carmier would not need to report it to Gao Wen as a great achievement!

In this world where extraordinary power exists, remote communication is not something that is unheard of. It is just a high level of magic and the cost is extremely high. It is precisely because of these two restrictions that its application is always limited to very narrow fields, such as one or two emergency communication channels mastered by the monarchs of various countries, or some middle and high-level professions need to communicate within a small range. At present, the only remote communication channel on the mainland that can be called practical and also widely used on a large scale is the magnificent wall built by the elves. That wall was built by the intelligent races of almost half of the continent seven hundred years ago. Its cost is so high that even today seven hundred years later, various countries still have not accumulated enough energy to rebuild another one, and the communication range of the magnificent wall is only one circle near the wall...

Carmire must have known these facts, so he was so excited to bring out the result. The only explanation is that he has successfully broken through the various restrictions of traditional messaging spells or messaging devices, as Gao Wen asked.

When Herty's thoughts were coming one after another, Gao Wen also felt a huge feeling in his heart. The first thing he was surprised was that Carmier actually made a visual intercom-level thing out...

His expected goal at the beginning was just audio calls, and even if it was not good, everyone could shoot a telegram... As a result, the level of this thing was immediately shocked by the fact that it was in place.

However, after a brief surprise, he woke up and realized that this was normal in this world. The sound-like spells that reproduced sounds and illusion-like spells that were almost holographic projection were not complicated. Their magic arrays before simplifying were only at low-level and intermediate-level primary levels. After Jenny completed the reconstruction and simplification of most basic rune groups, the arrays of these two spells had even become low-level intermediate things...

What is really difficult is always just the word "make the signal stable and remote transmission".

Due to the special attributes of magic, it can only be transmitted through symbols on the magic array, but cannot be transmitted through "wires", so it is extremely difficult to implement wired communication in this world, while wireless communication has always faced the problem of inability to simplify the magic array model of the communication spell and too many technical black boxes. It can be said that in this world with unique physical rules, it is much more difficult to achieve the goal of "stabilizing remote transmission of signals" than how to convert signals into sound and images.

This is the world. This always brings surprises to Gao Wen and always makes him at a loss. Workers in the world territory use laser welding guns and anti-gravity hoists, and he can't build a useful steam cylinder.

"Very good...very good..." After the surprise in my heart calmed down, Gao Wen couldn't help but repeat the word over and over with an extra happy smile, "Transportation and communication... are half solved, half solved..."

"What?" Carmier asked curiously, saying that he was a pure researcher, and he had been completely immersed in his projects recently and did not know about government affairs.

"No, nothing," Gao Wen waved his hand and then looked at the device, "Is it made out of the basic rune set?"

"Ninety percent of the basic rune set, but some more complex rune structures are used when implementing the function of magic oscillation frequency control," explained Carmaier. "This part of the rune structure needs to be engraved on a silver substrate, but fortunately, the number is very small, and we recently discovered that making an alloy of silver and crystal blue steel also has good magic stability. If you use this alloy to make a substrate, the cost will be controlled within the expected range."

"Is it easy for ordinary people to use?" Gao Wen continued.

"It's as easy as other magic machines on the territory to control the rune trigger."

Gao Wen continued: "Very good, I still have problems..."

Carmire floated slightly into the air, his tone was full of confidence, and his body emitted a slow flash of reserved and proud: "Of course, I'm ready to answer."
