"Lao Chi, you can work with peace of mind. What do you need? Tell me directly that I will deal with the messy things outside." Luo Yao said solemnly.

"clear."

Chi An knew that it was not easy to meet a good boss. A person had the ability. If he met an unreliable superior, he might not be able to achieve any great results in his life.

But if it is someone who understands him and supports him strongly behind his back, then this person can burst out with unparalleled energy.

"Is there enough manpower?"

"Now, I, Jia Bingwen and Wu Yulang, are really too busy to get busy. If I can increase the number of people, it would be the best."

"Do you have any familiar introductions?" Luo Yao said, "I'll go and invite."

"The people I know all work in other departments, and I guess they won't come here. Lao Jia and Xiao Wu should have people they know. I will ask if there is any suitable one, so I will introduce them."

"Okay, let's introduce it. The salary is the same as theirs, which means that they have to be subject to some restrictions on freedom of movement. After all, our job is different from other jobs." Luo Yao said.

"clear."

"You go and do it, I'll just take a look."

"OK."

Luo Yao walked all the way to the mailroom and added ten new express machines, which became bloated. At first glance, at least seven or eight machines were on.

As the director of the mailroom, Wen Xueren is guiding new students to take the plane to operate and listen to Japanese secret communications. His main direction is the Japanese Army's secret code communications, the Japanese Air Force's communications, the Ministry of Foreign Affairs' secret code communications and naval ship communications, which are temporarily shelved.

First, the mountain city is located in the hinterland of China, and the attenuation of electromagnetic signals is not the best place to monitor these two types of secret communications. Second, the students are still in the early stages. Although they are making rapid progress, there is still a way to go to meet the qualification requirements.

You can't start running before you learn how to walk?

"Webmaster, you are here." Wen Xueren arrived here, and he was like a fish in water. There was no one who disturbed him. He listened to whatever he liked, and his treatment was twice as high as before. He lived a free life. What's important is that in just over twenty days, he actually gained ten pounds.

He turned out to be thin and weak, and looked like he fell down as soon as the wind blew, but now he is much better.

And once he came, his military rank was promoted one level.

Even if the Telecommunications Office invites him back with twice the treatment, he will not go back. He is depressed and unhappy in a place. Is the money he gives useful? Is it possible to find an excuse to fire you at any time? Also, do they really want to invite him back?

Not to be able to learn from him how the "Missing Research Group" deciphered the Japanese Air Force's secret code.

"You guys are busy, I just take a look." Luo Yao himself often sends and receives newspapers, and his hearing is more abnormal, but he rarely shows it now.

In addition to those close to him, outsiders really don’t know that his hearing is not inferior to Wen Xueren, and he is even much higher than Wen Xueren.

"Webmaster, report to you." Wen Xueren ordered the students to continue working and invited Luo Yao into his office next door.

Luo Yao came in and saw that Wen Xueren's office was simply a small mailbox room. In addition to his own desk and a hardwood sofa for meeting guests, the small office also had a workbench that occupied one-third of the space. It actually housed three transceivers and various telecommunications equipment.

In addition to sending and receiving newspapers and listening to these electromagnetic signals with mysterious information, Wen Xueren likes to tinker with various telecommunications equipment.

In the words of later generations, this should be a radio enthusiast.

Wen Xueren didn't treat Luo Yao as an outsider. He generally knew that Luo Yao also knew technology, and he was his mentor, so there was no need to hide anything in front of him.

"Webmaster, listen." Wen Xueren handed Luo Yao a pair of headphones, asked him to bring them, and then took a box of tapes, placed them on the cassette-type audio player, and twisted the play button.

Didi...

The sound of the radio waves is very short, less than a minute before and after, but the sender's method is very fast and stable. When he heard it, he thought he had at least three years of experience in sending the newspaper.

The sending of reports is very coherent and completed in one go.

"Webmaster, keep listening!" Luo Yao looked up at Wen Xueren, expressing his confusion. He asked himself to listen to this radio wave.

Luo Yao did not take off his headphones, but continued to listen. After a moment, another radio wave appeared in his ears, which was not long.

But as soon as it appeared, Luo Yao judged that it was sent by the same person.

Wen Xueren did not press the pause button, and Luo Yao continued to listen. There were seven such radio sounds recorded on the bag, which were only three minutes long and only thirty seconds short. This was a telegram sent by the same person.

"Webmaster, I accidentally listened to this radio signal half a month ago. Because it was too clear, the signal could hardly be heard at any attenuation. And I had never heard it before, so I recorded it. Later, I heard the same signal at the same time. The time for this radio to send a message is very regular, every other day, and it is usually between 9:30 and 10:00 pm..." Wen Xueren has heard this signal and studied it for a while.

"This is the message I heard, with time, frequency, and call signs marked on it." Wen Xueren took out a stack of manuscript paper from the drawer and handed it to Luo Yaodao.

Luo Yao looked around and naturally recognized it at a glance with his memory. This was the number of the radio signal he had just heard.

"Do you have an idea?"

"Webmaster, I judged that the user of this secret radio station is a transmitter with at least three years of work experience. Moreover, his workload is extremely large to achieve such a fast hand speed. The most important thing is that according to my analysis of the signal, the signal is very clear and the attenuation is almost negligible. I judged that the radio station signal is somewhere near us." Wen Xueren said.

"scope?"

“Within about twenty kilometers.”

"Twenty kilometers, this is hard to find. There are many private radio stations in the mountain city that are not registered, let alone those secret radio stations. Your range is too large and difficult to find. And can you be sure that it is a secret underground radio station of Japanese spies?" Luo Yao asked back.

"No, but this signal is very suspicious."

"Such a secret radio station uses a special codebook, and it cannot be deciphered without a key. I think you must have tried deciphering it with the current Japanese communication codes you have mastered, right?" Luo Yao asked.

Wen Xueren smiled embarrassedly: "I tried it, the donkey's head is wrong."

Luo Yao nodded. If he really investigated, the manpower and material resources might be consumed, and there might not be a definite result.

This kind of radio wave signal discovered by accident is like a great fortune, and it is indefinitely.

"Webmaster, I actually want to ask you to help me listen to another radio signal recording." Wen Xueren smiled. If he was not prepared at all, why did he invite Luo Yao to his office?

Just because he discovered a mysterious radio signal, it turned out to be useless in the end. He also reported it seriously. Isn’t that uncomfortable?

"besides?"

"You will understand after listening."

Wen Xueren took out another tape, put it into the playback, and then signaled Luo Yao to put on the headphones again and unscrew the playback button.

A very normal message came into Luo Yao's ears from the headphones. After listening carefully, Luo Yao's eyebrows frowned slightly.

Wen Xueren did not disturb him and waited until Luo Yao finished listening to the entire tape before turning off the audio player.

"Webmaster, what did you hear?"

"Xiao Wen, these telegrams seem to be sent clearly. The first letter was sent by Shancheng to Yudu, and the second letter was sent by Shancheng to Xiangcheng..."

"Yes, webmaster, these are all clear-coded telegrams, and they were sent by Shancheng Telegraph Bureau." Wen Xueren said.

"Why are you listening to the telegraph from the Telegraph Bureau if you are fine?" Luo Yao asked strangely, although he knew that some people like to do things that ordinary people cannot understand.

Wen Xueren smiled embarrassedly: "Sometimes I work night shifts and can't sleep during the day, I like to listen to this 'drip' sound to fall asleep."

Luo Yao smiled and said it was understandable that the couple snored and became used to listening. Suddenly one day, there were too many cases of snoring and sleeping.

"Webmaster, don't you think that although the speed of sending messages in these two different telegrams is different, do their techniques have similarities?" Wen Xueren continued.

"You mean that when two 'points' are emitted continuously, the second point is lighter than the first point. When sending the number '4', there are four 'points', which are emitted continuously without any pause in the middle. This is very consistent with the four 'points' I heard before. It can basically be assumed that this may be done by the same person." Luo Yao analyzed.

"Listen again." A happy smile appeared on Wen Xueren's face. He immediately turned the tape back manually, put it on again, and pressed the play button.

Luo Yao was actually basically sure that this was the message sent by the same person, and it was the same machine, but in order to cooperate with Wen Xueren, he brought his headphones and listened again.

Then I listened to the previous message from beginning to end.

"You want to say that the telegrams in these two tapes were sent by the same person and the same machine, right?" Luo Yao took off his headphones and gave the answer directly.

"The webmaster is right. This person works in the Telegraph Bureau and uses the night shift to send private telegrams and deliberately speed up. After the speed of sending a person's newspapers is formed, it will rarely change, especially the radio operator who works in the Telegraph Bureau. Over the years, he has formed a physical instinct. It is not impossible to speed up, but it is difficult. It is even more difficult to ensure that no mistakes can be made during the speedup process." Wen Xueren explained excitedly.

"Xiao Wen, I understand what you mean. Don't tell anyone about this. I will investigate it. If it has nothing to do with Japanese spies, it is an ordinary case of custody and robbery. Just leave it to the police station." Luo Yao ordered solemnly.

"clear."
