However, after a brief surprise, he woke up and realized that this was normal. In this world, the sound-like spells that reproduce sounds and the illusion-like spells that are almost holographic projection are not complicated. Before simplifying their magic arrays were only at low-level and intermediate-level primary levels. Lao Gan, a miscellaneous scientist who is proficient in various magic, after completing the classification of most basic rune groups, the magic arrays of these spell inscriptions have even become low-level intermediate things...

What is really difficult is always just the word "let the signal transmit stably".

Due to the special attributes of magic, it can only be transmitted through inscriptions on the magic array, and cannot be transmitted similarly to wires 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 communication spells 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 this world. This world can always surprise Renault and always make him at a loss. Now there is more convenient energy. He doesn't need to build a generator or a steam engine diesel engine. After all, although magic is not very stable, it can be predicted that this is definitely the most popular in this world and the most convenient way to use the collected energy. On the contrary, he doesn't know the steam engine, and he doesn't even know the principle of the diesel engine. And now he uses magic to get all the video communications. He still wants to go far and away. What bicycle does he want?

"Very good...very good..." After the surprise in my heart calmed down, Renault couldn't help but repeat the word over and over with an extra happy smile, "If you want to be rich, build the road first. The road has been solved. If you want to guide public opinion and spread faith, this video communication is simply a magical tool... It's almost solved, it's almost solved..."

"What?" Celia asked curiously from the side with great joy. This girl is a pure researcher, and she has been completely immersed in her various major projects recently and does not know about government affairs.

"No, nothing," Renault skipped the topic and looked at the device, "How is the cost of this thing?"

"Ninety percent are first-level inscription inlays, but some more complex rune structures are used when implementing the function of oscillation frequency control of magic signal oscillation frequency." When talking about this technical problem, Celia explained happily, "This part of the inscription structure needs to be engraved on a silver substrate, but fortunately, the number is very small, and we recently found that alloys made of silver and steel also have good magic stability. If you use this alloy to make substrates, the cost will be very low."

"Can ordinary people use it?" Renault asked again.

"Uh...not yet... this person without magic can actually use it, but there are too many magic units now, and it is very complicated to operate. I will improve and integrate these units later. It will probably be almost done."

Renault continued: "Very good, I still have problems..."

Celia nodded repeatedly. She was very happy to answer Renault's question now and a little proud: "Of course, I'm ready."

A cheap, convenient, stable and reliable remote communication method, the role it can have in the process of social development is beyond doubt, especially at the moment when Renault destroyed the main force of the Iron Principality and the old nobles' resistance forces and began to integrate and build a new flame kingdom, its significance is even as important as those mutated dragon breaths that can destroy the old noble army.

There are many factors that restrict social development. For the Flame Kingdom, which has rapidly expanded its territory and increased its population, the two biggest challenges in maintaining the ruling power of the Flame Kingdom at this stage are transportation and communications, materials, personnel transportation capacity, construction capacity, information circulation capacity, response speed and response effectiveness of the entire ruling structure... These are almost all depend on the development of transportation and communication technology.

Excellent transportation can allow the rapid flow of materials and personnel within the territory, production and construction will be guaranteed, commerce will be developed, and the connections between various regions will become closer and not loose. In an emergency, it is also a prerequisite for ensuring that the army can quickly rush to the war zone. Excellent communications allow the Lord's Office and the Governor's Office to understand the situation in the entire territory, ensure that the intelligence in various regions is timely and smooth, and the Governor's Office can respond to various emergencies as quickly as possible. To achieve these two points, the development of technology and productivity must be relied on.

In Renault's view, the aristocratic feudal system of the Iron and Steel Principality was a manifestation of backwardness, but it was an inevitable result of limited transportation and communication technology. The rulers could not control the situation outside the territory in time, nor could they send troops outside this limit area in the shortest time. At the same time, the materials of a city were difficult to transport to other cities, which also destined to divide the aristocratic feudalism and divide the city and use the state. In fact, until the destruction of the Iron and Steel Principality, the aristocratic and scholars of the Principality still followed the following famous sayings:

The area where a lord can effectively rule is the farthest end that his knight can reach within two days and nights, and the area where he can achieve absolute rule is the farthest distance that his knight can patrol every day.

This ancient saying has been popular in the Iron and Steel Principality for hundreds of years, and is even very popular in many Principality territory.

On the contrary, the powerful kingdoms and empires, their senior spellcaster consultants usually hire some spellcasters who can communicate with eagles, because these spellcasters can give themselves the horizons, so the detection range is very broad. Last era, druids have always been a popular profession. Many kingdoms were keen to hire druid consultants. Even some principalities tried every means to hire druid consultants, because druid consultants can drive many animal partners, which greatly enhanced his vision.

Until the beginning of the fifth era, the craft of making long-distance reconnaissance magic props gradually became mature. Many empires and kingdoms began to widely use magic props such as magic balls, as well as some long-distance detection spells, which further expanded the absolute control field.

However, the Lord's Enfeoffment still cannot be replaced in the Nolan continent because it is impossible to directly detect big and small matters. Moreover, this kind of detection is only one-way detection. The detected side cannot give feedback to the other side, which means that the device developed by Celia and the others cannot interact with it.

This also leads to the lord being an indispensable position, because the lord can provide extremely rapid feedback on the situation in his territory in a timely manner.

Transportation and communication, the former has the speed of cement construction for several miles a day, and the latter has finally seen the achievements made by Celia and Gandalf's efforts so far, and these two problems that plague all rulers seem to have solutions.

"At present, this communication device uses a brand new marshalling group - most of its inscriptions are from ancient inscription technology, part of which comes from the druid spell technology, but the current traditional transmission spell method is still used in the occurrence and control of magic shocks," Celia explained to Renault with great enthusiasm. He jumped to the communication device and explained some technical details of the device to Renault. "Sadly, I still couldn't do what Reno said, how did the communication network transmit signals in the natural air? And the specified dialing capability you mentioned, I can't realize it for the time being, so this device can only operate within the coverage area where the extreme magic power spreads out."

Renault is also very interested in the technical details of this different world version of the communication network: "Magic coverage... Then did you create the transmitter and receiver I used to do?"

"Yes, the magic ripples generated by the magic crystal on this will spread outwards, just like you once described. Even if the water waves continue to spread out, the ripples generated by the magic crystal spread in the air, and the magic crystal on this device arrive at the magic crystal on another device. Therefore, I temporarily call this communication method 'magic communication'," Celia explained. "I have found a solution to use magic crystal as a 'relay' to continuously transmit signals, and have achieved success in a small range, but the specific effect after the transmission distance increases remains to be verified..."

"How do these communication devices pair or identify them?" Reynold asked again. "If I have a hundred such devices distributed everywhere, how can I use one of them to accurately connect to another specific device?"

"Well~ This is not possible yet. I have said before. There is no way to specify the transmission, only the information can be transmitted in a range." Celia was also a little distressed. She grabbed her long hair that she tied up for the sake of experiments, and looked very distressed and depressed. She had also studied this technical difficulty, but because there has been no progress, she would get the equipment out first.

To be honest, the communication device created by Celia and Lao Gan and the current completion of this device is much beyond Renault's expectations - not only at the technical level, but also at the design concept.
