"First of all, we had to get rid of the old 'square radio', not to mention that this model could not be used to screen the anchor and the listener in both directions, and the bigger obstacle was that no matter how loud the volume of the 'amplification technique' was, it was impossible to transmit the sound thousands of miles away." Roland replied.

André nodded in agreement with him, and then came up with a logical idea: "Is it possible to improve the 'hotel broadcasting' model and upgrade it to a national broadcasting network based on it?" ”

"Of course, it is best if this road is successful, but it should also be seen that there are many practical obstacles, first of all, the transmission distance of the 0-ring 'communication technique' is too short, only suitable for short-range broadcasting within 300 feet, and secondly, the line is too narrow, and it can only broadcast to 20 people at the same time, which is too far away from the grand goal of the national broadcasting network." Roland points out the problem.

"If multiple 'teleportations' are connected in parallel to form a spell array, the broadcast line can be expanded exponentially." Andre gave a technical improvement strategy, "At the same time, the 'teleportation technique' can also be upgraded, at the expense of increasing the level of the spell in exchange for a longer communication distance. ”

"Master Andrey, with all due respect, this kind of minor improvement is practical for an airship or a ship with only a few hundred passengers, but not for a town inhabited by tens of thousands. With this line of thinking, the cost of building a nationwide broadcasting network would be unimaginably high! Roland was frank in his dissentings.

"It's true that there is a problem of high cost, and this is precisely the problem that our mage class is most likely to ignore......" Andre Mo squeezed his big bald head full of wisdom, and fell into a long thought.

"If I had been entrusted with building a radio network in a megacity like Krasbourg, I would have managed to bypass the current technical hurdles and build a network for the city to communicate with millions of people over the air, and then use that network as a channel to load the broadcast system, so that I could do the task indirectly." After contemplation, André came up with a more abstract solution.

When Roland heard him say this, he naturally thought of the wireless broadcasting network on the earth, but Vares's technology is far from the level of using radio waves, and it is unlikely that he will build a broadcasting base station like the one on the earth, let alone launch communication satellites, how will André build his communication network?

Facing Roland's puzzled eyes, Andre smiled slightly: "There is a ready-made legendary spell that can create an invisible enchantment that envelops the whole city, and we can use this enchantment as a carrier to transmit various spell effects, including 'communication', 'amplification' and my own invention of 'communication technique', so it is not difficult to build a broadcasting network that envelops the whole city, you should be able to guess what I am talking about." ”

"Lost lock!" Roland replied without thinking.

Andrei nodded slightly.

Roland recalls that the locks he has come into contact with, such as the Kitland Lock, the White Gull Harbor Lock, and the Dragon City Lock, do have functions similar to wireless communication networks, as long as they get the permission granted by the locks, they can send messages to designated residents in the city and to designated places, and it is not difficult to create a broadcasting network on this basis.

"However, the problem is that the construction cost of the Lost Lock project itself is very expensive, and using the Lost Lock as the carrier of the broadcasting network, such as eating a piece of black bread with a gold dinner plate and a platinum dinner knife, is too expensive, not to mention that the Lost Lock is only a 'local area network' limited to the inner city, how to send broadcasts to those towns and villages outside the city that do not have the Lost Lock and are unlikely to have the financial resources to build the Lost Lock in the future?" Roland questioned.

"Sooner or later, big cities will have to build a lock, and this investment will never be wasted, as for radio and communications in rural areas...... This is indeed a tricky problem, and we need a magical network that is much larger than the Lost Lock as a communication carrier......"

Roland had an idea and blurted out: "For example, the magic net covering most of the planes and the heavens of the multiverse? ”

"This is the right direction to explore, it's a pity that mortals like us can't afford to get their hands on the Magic Net, and it won't work to use the Magic Net to transmit broadcasts, but ......" Andrei's smile carried a hint of mystery, "We have a low-end imitation of the Magic Net. ”

Roland understood: "You mean the Alpha Bank's spell bit financial network?" ”

Andre nodded lightly: "We have never imagined using this network to transmit sound waves, and there will definitely be many difficulties in terms of technology, whether it will work or not, and we will need to conduct some experiments to determine." ”

"Looking forward to your good news!" Roland took a sip from the teacup and started another topic: "Just now you mentioned the Lost Lock Project, and I would like to ask you about this issue." ”

André made a "please speak" gesture and looked at the unusually active young man across the tea table with a smile on his face.

"There is a small island in the North Bay that is my territory, located in the North Bay into and out of the Meteorite Ocean, the main channel of the strait, has a high strategic value, there are also important facilities such as a military port, an arsenal, a magic guide locomotive factory, and a giant eagle cultivation base on the island, so it is necessary to build a lost lock to maintain the safety of the island, there are not many institutions in the Far East that have the ability to contract the lost lock project, among which the strong and qualified ones are none other than the Naluo Order and the Beacon Mountain, compared to the better reputation of the Beacon Mountain, so I would like to ask you a question, How much would it cost to build a Mystery on the island on the same size as Kitland? ”

Roland had promised Sir Edric to complete the Mystery of Koras Island as soon as possible, and one of the purposes of this visit to Beacon Hill was this.

Andre didn't answer Roland's question immediately, and said unhurriedly: "The construction cost of the Lost Lock Project is quite expensive, so you'd better be mentally prepared." ”

Roland nodded, indicating that he was not ignorant of the market.

The so-called "Lost Lock" is simply a type of Plastic Legendary Magic, and its basic function is to create a spell enchantment that envelops a vast space.

There is no certain scope of the Mystery Lock, which can be limited to a single warship, a city, or as large as an entire continent or even a planet - such as the famous "Dragon Maniac Lock", which can affect all dragon creatures in the entire territory of Faeron.

The Mystery is essentially an enchantment, and this enchantment can be permanently and constant at a specific location, semi-permanent, or decaying over time. As for the other functions of the Lost Lock, such as the magic that automatically applies within the enchantment area and various supernatural powers, they are all "modules" that are additionally attached to the basic enchantment.
