Li Yongsheng heard some rumors from the bookstore, but he didn't care at all. In fact, when he was in the fairy world, he was a more independent person.

Now, except for the book pavilion inspection, the rest of his time is trying to set up a audio and playback station - on earth, this thing is called a radio station.

The Xuanqing plane has a device that transmits information wirelessly, called a messaging stone, which is a disposable product. It appears in pairs. The information is written on one piece and stimulated. The other piece can be received. Write a few sentences in front of it, and then the mission is completed.

This thing is not expensive, but it is not cheap. Most of the time, public news is conveyed by newspapers.

That’s right, there are newspapers on the Xuanqing Plane, and there are more than one, both official and private.

However, the sales of newspapers are not very good. Many people are illiterate, and those who are literate may not buy newspapers. Wait until other families finish reading it, wouldn’t it be enough to borrow it and take a look?

The newspapers here do not have very high requirements for real-timeness, but have almost strict requirements on the authenticity of the incident. Once false news is reported and the credit is broken, it will even be smashed.

Newspapers do not emphasize entertainment. There are too many people who are illiterate. Watching operas and speaking books is a good entertainment. Why buy newspapers?

Li Yongsheng had no intention of setting up a newspaper again - he had no money to do it, so he wondered if he should set up a radio station?

He started a radio station, of course, to facilitate the search for Yongxin. The information transmission here is too primitive and there is no effective way to find it. He really doesn't know how long it will take.

There are also radio stations in the fairy world, but they call it a sound and playback station, and the principle is different from the principle of the earth.

Li Yongsheng from Earth is very clear about the principle of the radio, and the sound and playback station in the fairy world also requires some means from the fairy world. The best choice is the Earth mode.

Although Li Yongsheng has some small money recently, he cannot waste it casually, so he is very cautious about this experiment.

On that day, he finally tried to produce a radio station and then made two more radios, intending to test it at a relatively long distance. After doing these, he was penniless again.

He would definitely not be able to do such a test alone, so he found Jing Junhong and asked the teacher to help provide staff.

When Teacher Jing heard his introduction, his heart was filled with excitement. If that effect could be really achieved, it would definitely attract the attention of the military - what does accurate and timely information mean on the ever-changing battlefield?

Jing Junhong volunteered to guard the radio station and coordinated with three children. Adding Li Yongsheng, four students from the school were in groups, each holding a radio, and directly leaving the monastery and running towards the distance.

It is said that this is the matter of the Waisha Chen class, and the Neisha student should not be allowed to interfere. However, after the first test of the radio effect, Teacher Jing immediately decided to invite two good teachers to witness this great moment together.

This experiment will not fail anymore. What we need to test now is just the distance of the spread.

The guy in the same group with Li Yongsheng was a guy named Yue Kai. The two of them carried a big box and ran out for more than ten miles. Li Yongsheng shouted, "Stop."

Yue Kai stopped and looked at him curiously. Wai Saisheng put his hand on the big box and outputted spiritual energy. Then the square box rustled.

After outputting a lot of spiritual energy, it kept rustling. Li Yongsheng frowned and twisted the round button slightly.

This original radio is not capable of frequency modulation, and Li Yongsheng did not think that there is a need for frequency modulation - it is only a radio station that can be made into a frequency modulation, so how expensive it is.

However, if you don’t do frequency adjustment, you still need to have fine adjustment.

Soon, a man's voice came from a rustling sound, intermittently, "They... have... two or three miles?"

"Teacher Gong?" Although his voice was very distorted, Yue Kai still heard it. The one who spoke was his teacher. He couldn't help but scream, "It's not just two or three miles? There are more than twelve or three miles."

"The spiritual energy they output is unstable," Li Yongsheng was still very familiar with the equipment he invented. "But this is normal. We can just rush to walk. They have to enter spiritual energy while talking."

Yue Kai was stunned for a moment, then reacted, and then pointed to the huge radio, "Is this thing... very powerful to consume spiritual energy?"

"It's more powerful now. If you're a little younger in the future, you may not be that powerful," Li Yongsheng hesitated for a moment and spoke with no confidence.

"Come on, I'll carry it," Yue Kai's interest came, and he continued to walk with the radio, pressing his hand to input the aura. While walking, he listened to the conversation of the three teachers on the radio.

Li Yongsheng couldn't help but remember that when he was in the earth, those old men who practiced in the park in the morning exercise were just one radio?

However, the radio on Senior Yue's hand was slightly larger, and it looked like thirty or forty pounds.

After walking for more than a mile, Yue Kai grinned and said, "This is really a waste of spiritual energy... Can't you use other methods?"

"It's okay to use electricity," Li Yongsheng smiled, "But this is unrealistic, right?"

People in the Xuanqing plane have not yet learned to generate electricity. When it comes to electricity, they are thunder between heaven and earth. However, people in the natural plane also admit that thunder and lightning contain extremely violent energy.

Yue Kai would have misunderstood, and he sighed helplessly, "Why do I feel that I have transformed into thunder."

"It's just a little spiritual energy," Li Yongsheng smiled disapprovingly, "It is said that some people can still use love to generate electricity."

This test extends to about 35 miles away. It’s not that I can’t collect it, but that both groups of people are exhausted and it’s not too late. If I don’t walk back, I may not be able to return to the monastery.

When we returned to the monastery, the three teachers had already prepared the meals and had a raw meal with four primary school students. Today's test went smoothly - in fact, it was still one-to-many to convey messages to people thirty-five miles away, which was really a sense of accomplishment.

"I'll get a few horses tomorrow," Gong Zhiyu looked excited, "I always have to measure this data solidly. Xiao Li, do you think one hundred miles can guarantee it?"

"If the radio station is set up a little higher, one hundred miles will not be a problem," Li Yongsheng was quite clear about this.

The three teachers exchanged their eyes and spoke in unison, "Then go to the Star Gazing Tower!"

After eating and drinking for a while, Teacher Gong remembered something and looked at Li Yongsheng with a look, "What I see is that you want to make a newspaper that you can listen to?"

Li Yongsheng smiled and shook his head, "Of course, it is to give priority to the military and civilian markets, and there is not much demand now."

Teacher Gong hesitated for a moment and finally said, "Xiao Li, it's okay to supply the military properly. You didn't expect that this cost, even the newspapers would be compensated even more... The radio is not cheap, right?"

Li Yongsheng nodded with a smile, "Thank you, Teacher Gong, for reminding me, but this radio really doesn't cost much."

It won't cost much? Teacher Gong glanced at him, thinking that this kid really dared to brag.

Another teacher named Xiong finally spoke, "It won't cost much... how much is that?"

Otherwise, most of the teachers in the monastery are mindless and often leave no room for questions.

"If you are in batches, you can outsource it, which is about five silver dollars," Li Yongsheng calculated and gave an answer. "No matter how large the quantity is, it can be controlled to about four silver dollars. There are many work that a beginner can do."

The educational level of the Xuanqing plane is not balanced, and the labor costs are also relatively different. The monthly salary of a fresh graduate student can basically reach one silver dollar. If it is not developed within the system, the monthly salary will be higher - such talents are rushing to be needed in society.

Of course, students who enter the system will have a lower initial salary, but they will develop step by step and will have the opportunity to raise their salary, not to mention physical goods, land and other benefits. Once they have certain official positions and real power, they will also have gray income.

But it would be good if a beginner, or a primary school graduate, found a job with a monthly salary of 500 yuan.

Of course, if those who have a skill are not listed here.

If those who have never been to the monastery are illiterate, they can find work with a monthly salary of 400 or 500 yuan by working hard, but that is to eat youth. Generally speaking, they will have a monthly salary of 300 or 400 yuan.

A family of six must have at least two such laborers, and some elderly and children earn a small amount of money to supplement their household income in order to maintain a relatively stable life.

The radio is a fine object, but the primary processing can be left to some low-level laborers.

"Four silver dollars," Teacher Gong couldn't help but be amazed. His monthly salary was only two silver dollars, and with some other benefits, it would be more than three silver dollars a month. "You can only buy this thing if you have a salary of one and a half months."

"Four silver dollars are the cost!" Teacher Jing glared at him fiercely, "Xiao Li always wants to make money by selling this thing, right?"

"At least two months, the whole family will not eat or drink," Xiong said in a muffled voice. Their income was actually similar, but he was very curious, "What did you buy this thing?"

"That's what I said," Teacher Gong laughed, but his eyes were rolling, "I always feel that if I were to do some programs like Xiao Li said, it would be more popular than newspapers...it doesn't require literacy."

"Buy such an expensive thing home just for entertainment?" Xiong Zhiyu shook his head disdainfully, "I want to say that it is only useful in the army. It is useless for ordinary people to ask for this."

There is no way, as soon as new things come out, not everyone can see his prospects.

Li Yongsheng smiled but said nothing, thinking that you don’t know. The experience of radio in the earth world was once the only high-end home appliance in the family, and the price was also very expensive.

Teacher Jing was already very satisfied with the test results. He didn't want to hit Li Yongsheng, so he said again, "Xiao Li, I think if the radio can also convey words and communicate with the radio station, the application range will be larger."

I asked for a walkie-talk, and Li Yongsheng looked at him in surprise: I just got the radio, do you want to make the walkie-talkie?
