"Please sit down, do you have anything to do?"

Jiayi looked at the mage in front of him. He didn't look old, but he was over thirty years old. He did not restrain his breath and had a mage badge on his chest. Judging from his breath, although he was not a white-robed mage, he should not be too far from the breakthrough.

He was wearing a more formal robe and seemed to have come here specially, but Jiayi didn't remember having invited anyone at all.

"Hello, Master Jiayi, my name is Fesden. Today I came here to ask for a meeting. I have a question to ask you."

Jiayi was sitting in a while and looked like he was listening. Then he heard the mage opposite say, "Master Jiayi, do you still remember when you published your telegram paper, and finally said something about electromagnetic communication."

"You mean radio?" Jiayi thought he was here to discuss energy conservation, or felt that he had discovered some weaknesses in energy conservation, so he came to discuss it.

The hot mass said that it was getting colder now, but it was impossible to get colder immediately. Jiayi hid the limelight at the moment when the energy conservation was growing. Now that everyone has become more rational after coming back, people often discuss with Jiayi with questions about the hot mass.

Some really have questions, while others still hope to overturn the case for hot quality.

"Do you call this a radio?" the other party muttered in a low voice, "Yes, it's this. I'm very interested in this. I've been studying it for a while, but some parts are not particularly understandable and stuck."

Fesden said as he looked at Jiayi expectantly, but Jiayi was a little embarrassed: "Ah, but I didn't study much about radio. I just wrote an idea at that time."

At that time, he was just a trap of bad taste and was not prepared to study it in depth. Although he also had some ideas, he is currently paying more attention to some thermodynamic research and is not prepared to apply electromagnetics.

The direction he set for himself has always been the study of water and fire. Water represents matter, fire is temperature, and in the future it represents energy, and in the end, it is the combination of matter and energy.

Fesden said: "No matter what, this is the first one you proposed. You must have some special understanding of the radio you mentioned. I have already had a preliminary plan for the research on radio, but it feels very unpractical, so I want to come and ask for advice."

"Then tell me what problems you encountered. I think I can help."

Fessendon took out a small metal disk, and a magic array was arranged on it. At the top of the metal disk was an antenna standing. He took out another two disks and let them go, introducing to Jiayi: "This is the transmitter I made. The original telegraph machine has been improved. Using ultra-high frequency currents can emit high-frequency radio waves. When speaking on the magic array, the vibration of the sound will be converted into the vibration of electromagnetic waves and emitted. After the other transmitter is received, the current will be converted through electromagnetic induction to drive the vibration of the film and converted into sound."

As he said that, he also demonstrated and spoke above one magic array, which indeed caused another magic array to vibrate and make a sound.

Jiayi felt a little puzzled when he saw it: "Aren't you already very mature? Is there any other problem?"

"Of course, there are still big problems." Fessenden would stop the magic circle, "The distance is too short. Telegrams can almost pass through the entire continent to pass information, but my, the radio, cannot even cover Mosacher."

He frowned as he said, pointed to the small antenna on the magic circle, and continued:

"I have calculated that if I want the broadcast to spread to both sides of the strait, the nearest shore between Leizhou and Beisenzhou, my antenna must be at least 15 feet. If I want to spread far enough, I even need to build an antenna up to hundreds of feet, which is not practical at all."

Jia was a little puzzled when he heard this. It was nothing to build an antenna that cost dozens or hundreds of meters. It was able to transmit sound, which was much more convenient than telegraphs.

"Then it's nothing to build an antenna. After the magic array is improved in the future, the power will definitely be reduced. Just build a broadcast tower in Moshache, and the sound can be transmitted to the opposite side of the strait. Is there anything wrong with it?"

"But, it can't be carried with you. Can you only be fixed in one place? This is too impractical. I hope that everyone can use it like a telegram, rather than only building such a tower in each mage association, but only transmitting some unimportant information. Such information can be made using copper crystal telegram, and the confidentiality is better."

Jiayi understood what he meant. He was thinking about radio and radio himself, but Fesden was thinking about mobile phones. With current technology, mobile phones would definitely not work. If you want to realize a mobile phone, you would definitely need to build a base station. Otherwise, the power of the mobile phone could not transmit electromagnetic signals far away.

Jia looked at Fessendon and laughed, although he didn't laugh out loud: "Ha, I think your thinking is wrong. You shouldn't be used as a communication like a telegram. In fact, you just need to build a high-power broadcast tower to send information, and others can use this simple magic array, accepting only information, and not sending it out."

A simple radio is much simpler. I believe many people still remember the ore radio in the physics textbook, but the radio station is much more complicated.

Fesendon seemed to understand a little: "It's like... like..."

"Like a newspaper, it is actually more like a telegraph public channel. The telegraph public channel also requires others to keep the radio silent. Otherwise, it will affect the end of the information, and the broadcast will not be so troublesome. The rest of the people can only receive information, but not transmit it, and can directly hear the sound, even those who are illiterate can use it."

Although the prophecies of each country are different, most people know a little common language. Thanks to the Supreme Parliament, which is the common language among mages designated by the Supreme Parliament. Unless it is too remote, even if you can't speak, you can at least understand a rough idea.

"Thank you, thank you." Fessenden quickly stood up and looked at Jia Yi's luggage. "Thanks to your answer, otherwise I would have thought my research was worthless. Fortunately, I came here to ask you, otherwise I would have given up on this."

Jiayi shook his head and did not dare to take credit: "This has nothing to do with me. It was all your research. Even if you don't have me, this plan will be proposed soon after your paper is published and discovered."

Fessenden's thinking was a bit off because of the telegram. After being born to Jiayi, he understood everything and immediately discovered the potential of broadcasting.

He was so excited that he couldn't sit down, so he thanked Jiayi: "This is thanks to your wake-up, otherwise I don't know when I will understand it. Even after publishing it, I don't know when I will be discovered. And all my ideas are given by you. Speaking of which, you have research on sound wave detection, and there are telegraphs in electromagnetic aspects. The connection between sound waves and radio waves was also mentioned in that paper. If you want, I'm afraid I will fall behind you like Walker."

Jiayi was a little puzzled: "Who is Walkern?"

"Workern is my friend. Your first copper crystal telegram mentioned electromagnetic telegram. He felt very excited when he saw it and wanted to study it. Unexpectedly, just as he had some idea, you gave the electromagnetic telegram plan. Master Magnay also gave a complete magic array. Although this is a good thing, it makes communication between everyone very convenient, but it also makes all his hard work in vain and is a big blow."

"I'm so sorry, your friend is okay?" Jiayi didn't expect to meet his mischievous friend who was a prank at the time. He felt a little embarrassed. Thinking about it carefully, the approach at that time was indeed a bit inappropriate, wasting a lot of other people's time and effort.

"Fortunately, he was proud of losing to you and His Excellency Magnay. He was just hit and went out to relax. I studied radio to set an example for him and wanted to cheer him up. It was impossible for him to be so unlucky forever."

As he said that, he laughed: "Fortunately, you are now turning to the study of thermodynamics. If you are still studying electromagnetics, I am really afraid that you will be able to research radio."

Jiayi felt a little embarrassed and smiled a little dry: "Hahaha, it's not such a coincidence. Your research is great. I'll introduce you to Lord Magnay. He will definitely be interested in this."
