"First of all, this is the lowest level, the 4-ring plastic energy is a secondary call technique, the call range is limited to the Vares Tianyu, and the call time is 10 minutes per cast level; Then there is the 5-ring intercom technique, which expands the communication range to the entire plane; Finally, there is the 6-ring advanced communication technique, which can talk across planes. With a proud smile on his face, André introduced Roland to three different levels of "conversational skills" named after him.

Roland stood up and bowed to the red-robed legendary archmage, and said solemnly, "Master Andre, on behalf of the five million people of the Far East under the rule of the Kolas government, I would like to pay you the highest respect!" Your genius invention will not only bring great convenience to our lives, but will also completely change the thinking and lifestyle of our generation! A few years later, when we look back on the past, trying to find a coordinate point for the rapid social and technological innovation of the new era, and looking for a milestone towards a new era of civilization, I think it must be the great 'Romanov Talk'! ”

Andre's expression gradually changed to solemnity, he supported the table with both hands, slowly stood up, and bowed to Roland with the same solemn demeanor.

"I am ashamed of His Royal Highness the Prince's praise, this invention has not yet been tested in practical application, and the new type of call magic guide that is trying to apply it is still in the laboratory, is this technology really practical? Frankly, I don't know what to do...... If you want to change the way of life of our Far Easterners, replace the long cycle of correspondence with fast 'telephony', we need not only a laboratory, but also dozens or hundreds of factories that produce magic intercoms, and this work can only be done by you, if this invention can advance the civilization process of our generation by a small step, then you have half the credit. ”

Nikita burst out laughing, and couldn't help but complain about her father and boyfriend's hypocrisy: "Don't be so serious, okay?" As if he was a big man who saved the country and the people! ”

Mrs. Anna glared at her daughter in disgust and whispered in Nikita's ear, "Don't be naughty, when you grow up, you will understand that when a man feels a sense of duty, it is often his most attractive moment." ”

Nikita nodded half-incomprehensibly, pondering the meaning of her mother's words.

Technical support has been put in place, and Roland is very pleased with the cooperation method proposed by Beacon Hill. The invention of Andrei and Anna will be licensed to the government of Kolas free of charge, is this considered a dowry paid in advance for their daughter? Roland didn't dare to think deeply. As for the two masters, Saizeriya and McManus, both chose to exchange their inventions for shares of "Beacon Hill Offa Technical Services", so that the patents of "Saliya Photographic" and "McManus Fax" were held by the company, and the company authorized the government of Kolas to use the above inventions, charging annual royalties, and after 20 years, the patent protection period expired, and the government of Kolas and the residents of the kingdom could use these technologies for free.

This cooperation model reflects the strong support of the masters of Beacon Hill for Roland and the Colas government behind it. On the contrary, if they are not optimistic that the Kolas government can survive for a long time, instead of collecting royalties from year to year, it is better to ask Roland to buy out the right to use spells for 20 years at one time, and take a large amount of money to settle down.

After negotiating the authorization of the four spells, it was already evening, and Roland accompanied Andre's family to a warm family dinner, after which Nikita was dragged by her mother to take care of the pomegranate orchard, leaving the two men to drink tea and chat.

"Mr. Andre, in addition to technical support in the field of communications, I have two difficult problems that I would like to ask for your advice." Roland pours tea for the legendary archmage.

"If you have any questions, just say it, don't dare to advise, let's communicate." Andrei was very interested in the whimsical ideas of his son-in-law-to-be, and his smile implied anticipation.

"On the first day I came to Beacon Hill, when I was disembarking at the pier, I heard the magic radio on the pier broadcasting advertisements for business promotions, which gave rise to some potentially unrealistic associations, how great it would be if every household in the Far East could listen to the radio from the capital, and our government departments could communicate major events to the people through radio, carry out national mobilization, publicize policies and regulations, and non-governmental departments could also provide education, public welfare, literature and art, entertainment and commercial advertising and other services through radio. This will make our lives more convenient and colorful. ”

Andrei listened quietly to his idea of establishing a national broadcasting network, and replied thoughtfully: "This is a very grand idea, as for whether it is unrealistic, let's not rush to conclusions, how about deducing the feasibility from the technical level?" ”

"You're an expert in this field, and of course I'm listening." Roland said respectfully.

"Let's first review the current two mainstream broadcasting models, these two models are suitable for different occasions, although they are not yet popularized in the people, but they are not cutting-edge technologies, you should understand." André cast an inquiring gaze.

The construction of a national radio communication network is an important project that Roland plans to implement after the initial completion of the transportation construction in the Far East, and has long been prepared for this, collecting and reading a large number of relevant materials about the "magic broadcasting" industry, and immediately taking over the topic thrown by Andre and talking eloquently.

"The broadcasting modes that are currently commonly used in Vares countries are mainly divided into two categories: 'square' and 'hotel', which are suitable for different occasions and provide services for different customer groups."

"It's a good summary, can you specifically analyze the differences between 'square broadcasting' and 'hotel broadcasting'?" Andre asked with a smile, as if he had returned to the graduate class of the Shaping Energy Department at the Arcane Academy in Beacon Mountain.

"Let's start with the 'square mode', which is the oldest and most common mode of broadcasting, in fact, the word 'radio' comes from this, which means 'to speak in the square'," Roland clearly explained the history of the development of broadcasting technology in Vares, "At the beginning of the civilization era, the countries of Vares, there was no empire that unified the vast territory, and the government institutions were mainly embodied in the form of urban autonomy, which is what is called today" The city-state has a population of only 35,000 people and can become a politically and economically independent state, and the number of public servants from the lord down to the city-state is not more than 100, and the way of holding political activities is also relatively rough, that is, the citizens are called in the square outside the city hall, and government officials and respected citizen representatives can give public speeches and talk about their ideas on the podium set up in the center of the square. ”
