I didn’t expect this to be the radio, it was so magical, the sound could be heard from such a small box, which was even more magical than magic.”

The short mage couldn't help but sigh as he heard the sound coming from the radio.

The tall mage was also shocked, but he was unwilling to admit defeat: "What's so great about this? It is said that the radio tower is in the parliamentary area and is not far from here. It is not far away than using wind-type magic to wrap the sound and it is not far away. Moreover, it is only possible to hear it yourself. The confidentiality effect is better. Unlike this, the sound can be heard outside the house."

The short mage did not refute. He knew that his companion was just dissatisfied. This was not comparable to the voice transmission of wind magic. It could only tell one person or several people, and the broadcast could transmit the sound to hundreds of thousands of people at the same time, and the voice was farther away than the companion said.

As for what he found out, the current broadcast has covered hundreds of kilometers nearby, and will be transmitted to both sides of the strait, or even covering two continents.

Even legendary wizards do not have this ability in legends, and can spread the sound throughout the continent.

However, imitating telegraphs and radio, the current legendary wizards really have the possibility of sending messages to the entire continent through electromagnetic waves, but they can only be received through telegraphs or radios.

The next day, the whole Mosacher became boiling, and the radio in the store was sold out immediately. At the same time, the store notified that the next batch of goods would start to be discounted, and the price almost doubled, and the supply was still in short supply.

Many mages have to make it by themselves. Although the quality is a little worse, it is enough to listen.

Radio was unexpectedly popular in Mosacher. Even though Jiayi and the others thought it would be popular, they did not expect that radio and radio opportunities were so popular. In Jiayi's opinion, the programs inside were not rich and seemed a little barren.

But now these are not problems. Wilmot looked for Jia again, and there was Fersonden next to him.

"Congratulations, radio is so popular, you should be famous now." Jia Yi said as soon as he entered.

This is mainly for Fessenden, who has long since been no longer interested in this reputation.

For Fessendon, although this reputation is good, the most important thing is that he has a relationship with Wilmot, which he never dared to think about before.

He stood behind Wilmot and said, "It's all up to everyone's efforts. I can't build a radio station by myself. And I would like to thank you for your reminder. Whether it's the inspiration of the radio or the ideas of the radio tower, you provide it."

Wilmot also said: "He is praising himself."

Jiayi also laughed and said, "I just talked, I have no credit. Is there anything you can do to come to me?"

In fact, Jiayi's role in radio has been published by some newspapers, and Feisenden and others did not hide it. The person who first proposed the idea was Jiayi, which could be found in the paper.

Nowadays, Mosacher's news is very fast, and newspapers are very sensitive to news. In order to attract readers, they often spend their efforts to dig deep into a message.

As an emerging industry, journalists are not considered professional, but they are very dedicated. Unlike before Jiayi traveled through time, reporters could even compile a news by themselves. No matter what hot topics are suitable or not, they are rushing up.

The legendary human blood steamed bun.

Wilmott said: "The comments you made on this broadcast are very good and have given us great help. We are planning to set up street lights and electric lights in Mosacher. I want to invite you to join as a consultant."

Mosacher actually has street lights, but it is an oil lamp, which is not very bright, and many of them have been damaged.

Jiayi showed a embarrassed look: "To be honest, I am busy with experiments now and I am not very free. This matter is too time-consuming. I can only say that if I really do something, I won't be able to do it."

This kind of large-scale engineering tests the team. For Jiayi, it is better to go back to the laboratory to do some experiments. Of course, he welcomes him by building street lights.

Fessendon said: "It won't take you too much time, at most it's a little more than broadcast. You don't need to do the specific implementation of the construction, but you just need some details to give some suggestions. You proposed that you should add an insulation layer to the wires as soon as possible, which is something we didn't expect."

For the mage, electric shock is only a trivial matter. The voltage used to light the light last time was not high, so no one cared about it, but it would be dangerous if it was touched by an ordinary person.

Wilmott also said: "The construction of street lights will put Fessendon in full responsibility. You are just a consultant, just give some advice, it won't take much time."

Jiayi looked at Fesden in surprise: "You still want to make street lights? Will it not delay your magic learning? I feel like you are about to break through and become a white-robed mage."

Fesden smiled bitterly: "Not everyone is like you. You can make progress with just working hard. I have been stuck here for quite some time. Although I feel like a breakthrough after inventing the radio, I don't know when it will be true. I will be able to become a white-robed mage in my life. I am almost at the top of my career as a radio. It is the same opportunity for me to host the construction of street lights, just like broadcasting."

Everyone has different talents. Jiayi is not the best one, but what is terrible is that he has been improving all the time. He only got stuck for a little time before becoming a white-robed mage.

Fessendon seems to be preparing to specialize in engineering, but in fact, the subject has a lot of potential, but it is more difficult to reach the top level and consumes much more resources. Most engineers work for others, and even if they can build a floating city, they will not belong to them.

"We can only pay you if you become a consultant, otherwise it would be like this broadcast, and you would have made contributions but you would not be able to repay you," Wilmott said.

"Can I replenish it? I'm now accepting the position of consultant." Jia Yi looked at Wilmot with a gaze, feeling as if he had missed hundreds of millions.

"What do you think?"

"If I really want to say it, I want to say it." Jiayi only dared to say this in his heart, without saying it.

After pausing, he said: "The radio is now built, but like a newspaper, there will definitely not be only one radio station. You should divide the frequency bands well to avoid conflicts, and pay attention to avoiding someone who builds a radio station to spread bad news. Especially if those cultists build a radio station to preach missions in private, the impact will be bad."

Wilmot nodded slowly, this was indeed a question to be paid attention to.

Telegrams and radio are gradually developing, and the monitoring of telegrams and radio will definitely gradually develop, which is inevitable.

It was still early to leave the Supreme Council. Jiayi went to the college again. Today it was his class time. Although his class was not a compulsory course, there were still quite a lot of students willing to come to class.

Although his teaching level is average, it depends on who he compares with. Compared with other professors in the college, his classes are already thorough and vivid and interesting. The only thing that makes people dissatisfied is that he has more homework assignments, but now he no longer takes math classes and has less homework, which has become more popular.

As soon as Jia entered the classroom, he saw a student coming down from the podium and put something on the podium.

"Sankochia, what are you doing? You're not trying to do something prank, right?"

Jiayi suddenly made a sound and scared Sankochia, which really scared him up.

He patted his chest and said with a little depressed feeling: "I'm not crazy yet. Is there any prank that can make a mage difficult? This is the newspaper clipping I made, professor, please take a look."

"Newsletter?" Jiayi came to the podium with doubts. What newspaper clippings were specially meant to let him see them with his own eyes?

"It's actually my question. Haven't you figured it out yet? Why did this question suddenly appear in the newspaper?"

Jiayi looked up at the students below, and they all looked up at themselves, especially Sankochia. The boy stared at Jiayi with his eyes straight at Jiayi. It has been several days since Jiayi's choice question about raising and car, and he thought the popularity had passed.

"Teacher, the answers above are different from what you said. The day before yesterday, this question was published on the radio, and we all heard it. Then many people wrote to the newspaper to discuss this question, and most of them said they should not change it."

Jiayi just glanced at the newspaper clippings, but it said that it should not be replaced. Not everyone thinks so, but there is a choice in the newspaper publishing.

"You think so too?" Jiayi looked at the students below with some disappointment, "If it is true, you should really study the probability issue."

He began to write on the blackboard: "I said it simply. If the first choice is wrong, the host will open a door and change the choice. The probability of choosing the wrong choice is 2/3. Then, the probability of choosing the right choice is 100%. That is to say, the probability of winning the winning after the first choice is 2/3*100%=2/3.

"If you choose the right first time, the host will not change after opening a door, the probability of choosing the right first is 1/3. If you don't change, the winning rate will be 100%. If you don't change, the probability of winning is 1/3*100%=1/3. Do you understand now? The probability of winning is twice as high as not changing. Should you change it?

"Okay, who can help me contribute this issue to the newspaper, let's go to class next."
