The secret war is silent

"Did the call come from dad?"

"Um."

"Have you come to investigate?"

"It's okay, don't worry. Has Mr. Osborne come back?" Luo Yao said nonchalantly. If Dai Yunong was really to blame, he wouldn't have called him to scold him.

"I'm back, I don't seem to be in a good mood." Gong Hui nodded.

"Hey, sympathy is overflowing, but those children are indeed pitiful. There is nothing we can do. What we can do now is to defeat the Japanese invaders as soon as possible in order to give them a stable life." Luo Yao sighed.

"Is dinner ready, Lao Cao?"

"about there."

"Call everyone over for dinner..."

…

At the dinner table, Luo Yao solemnly introduced Tian Shoushan and Wen Xueren to Osborne, and told him that these two people would join their "secret research team".

Tian Shoushan is proficient in Japanese and telegraph sending and receiving technology.

Although Wen Xueren is not highly educated, he has extraordinary talent in sending and receiving secret codes, and he may have unexpected surprises especially in interception.

Osborne was of course very happy to have an expert who was proficient in Japanese. The information he brought about deciphering the Japanese military's diplomatic secret messages played a big role.

The more people there are, the happier Osborne is, which at least shows that the military command attaches great importance to him. Otherwise, he would not be equipped with so many assistants to cooperate with his work.

However, he still hoped to get into work as soon as possible, such as intercepting the Japanese military's secret communications and then deciphering them, but Luo Yao told him that their first task was to train a group of usable talents.

…

Fourth floor, radio room.

"Xiao Wen, you are a transceiver. I will not test your ability in this area. What I want is the ability to intercept and intercept local secret communications." After dinner, Luo Yao brought Wen Xueren up. said.

"Then what do you want to test me for?"

"You first listen to a few tapes here and remember their characteristics carefully." Luo Yaodao, "Then I will ask you to find them from dozens of sets of tapes. You can only listen to each set of tapes three times at most. .”

Wen Xueren thought for a moment and nodded.

Not many such tests are done in the United States, because it is a very difficult test for a person's hearing, and only some people with abnormal hearing can do it.

This naturally aroused Osborne's interest.

Luo Yao selected three sets of tapes and labeled them "A, B, C" respectively, and asked Wen Xueren to put on headphones. Each set was only ten seconds long. After listening, he changed to another set.

After listening to it three times, Luo Yao took off Wen Xueren's headphones: "How are they? Do you remember all their characteristics?"

"Yeah." Wen Xueren nodded.

"Very good, now there are twenty groups of radio signals in front of you, all of which are marked with numbers. Follow the same method just now. After listening to them, tell me which three groups of them are the signals you just heard, and what Point them out!" Luo Yaoxia Fei took out twenty tapes.

Put on your headphones, hit the first tape, and press play.

Tian Shoushan on the side also curiously picked up an earphone and listened along, while Luo Yao didn't wear any earphones and just listened to the sound leaking from their earphones.

This kind of test was the first time for Wen Xueren. Looking at his expression, he was still a little nervous. This was a big test for his hearing.

In the radio station room, except for the "didi-dip-dip" sound of the radio signal, there was almost no sound.

It only takes about ten minutes to go through it all.

Second time.

The third time.

There was a two-minute break in between.

Turn off the machine.

"How's it going, Xiao Wen, is there any result?" Luo Yao asked with a smile.

"Sir Luo, are you sure that only one of these twenty sets of signals is consistent with the first three sets of signals?" Wen Xueren asked.

"Oh, do you have a different answer?" Luo Yao frowned and asked.

"I think the signals of Group 4 and Group 17 are from the same source. They are from the same signal source as the Group A signal just now. The Group 9 and B signals are from the same signal source. There are also Group 13 and Group 19. The same signal source as Group C!" Wen Xueren couldn't help but clenched his fists when he said this.

"you sure?"

Wen Xueren's eyes shrank for a moment, and then he seemed to muster up the courage and said seriously and firmly: "I'm sure."

"Old Tian, ​​you heard it too, what do you say?" Luo Yao didn't answer, but turned to ask Tian Shoushan.

"I only heard that the fourth group was the same as the A signal. As for the rest, I didn't hear it." Tian Shoushan lowered his head in embarrassment.

"Okay, then we don't need to listen with headphones, just connect the speakers and listen together to see if Wen Xueren is right." Luo Yao still did not announce the answer, but asked everyone to listen again.

"Didi..."

In the radio station room, there are all people who have been trained in cipher codes. They are even very skilled in sending and receiving telegrams, but when it comes to distinguishing code signals, not everyone can do it.

In the ears of most people, these radio signals are the same, and there is no difference. Only in the ears of people with particularly sensitive ears, these radio signals have subtle differences.

After listening to it for one round.

Tian Shoushan seemed to have noticed something wrong, and his face looked a little surprised.

After listening to it again, Wen Xueren's eyes became more certain, his face seemed much more relaxed, and his clenched fists loosened.

"Xiao Wen, why do you say that the signals of Group 4 and Group 17 are from the same source as Group A? Is there any basis for this?" Luo Yao asked directly.

"Sir Luo."

"Just call Team Leader Luo."

"Yes, Team Leader Luo." Wen Xueren said, "Everyone should have heard that the fourth group of signals has the same origin as the A signal, and there is no objection. But why should I say that the 17th group of signals has the same origin as the A signal? Based on the judgment of his reporting method, this person's reporting method should be that his index finger and middle finger are close together, and the middle finger will coordinate with the index finger to touch the key. This should be his subconscious action. If you don't pay attention, you won't feel the slightest movement. As for why I say these two signals are from the same source, my judgment is that the person who sent the signal changed a new electric key!"

Before Luo Yao spoke, Osborne clapped his hands first. Although he was still learning Chinese, he could basically understand what Wen Xueren said.

"Very good, Wen, you are the most talented telegraph operator I have ever seen. You are exactly the person we need." Osborne said very excitedly.

"Team Leader Luo, am I right?"

"Yes, these two signals do belong to the same radio station and were sent by the same person. They just changed the key." Luo Yao nodded. He arranged the test. He naturally knew what was going on. Of course he , he could also hear it, but what he didn't expect was that Wen Xueren also heard it.

Hearing this, Wen Xueren breathed a sigh of relief obviously.

Needless to say, Wen Xueren was right about the last two. Of course, Luo Yao still asked him to explain the reasons for his judgment.

"Yes, Xiao Wen, you have passed the assessment and can officially join our team." Luo Yao solemnly announced.

"Thank you, Team Leader Luo."

"Okay, that's it for tonight. Let's go back and rest."

"Luo, I want to talk to you?" Osborne stopped Luo Yao who was about to leave.

"OK."

…

"Luo, I want to see a doctor tomorrow. My eyes are a little uncomfortable." Luo Yao followed Osborne into the office where he worked.

"What's wrong with your eyes? Does it matter?" Luo Yao asked in surprise.

Osborne shook his head: "It shouldn't be a big problem, it's just some inflammation."

"I think you should have a comprehensive physical examination. Tomorrow I will ask Translator Qin to accompany you to the best hospital in the mountain city. What do you think?" Luo Yao said.

"Oh, that's great, thank you very much." Osborne said gratefully, "By the way, there is one more thing I want to ask you."

"you say!"

"I have met a friend, and I would like to invite her to the mansion as a guest. Do you think it's okay?" Osborne asked hopefully. After all, the work here is special. If he wants to bring people in, he must get the approval of the person in charge, Luo Yao. agree.

"Female?" Luo Yao frowned slightly. He knew that Osborne was not a peaceful person, but he didn't expect that he would hook up with her after just a few days in the mountain city.

"A little girl, she's very cute."

"Mr. Osborne, you know that there are many Japanese spies in Shancheng. They are very good at disguise. If this girl approaches you with other purposes, what will be the consequences?"

"No, no, Luo, you misunderstood. Lu is just a simple college student. There is no way he is a Japanese spy." Osborne hurriedly defended.

"Whether she is a Japanese spy or not, it doesn't matter what you say, nor does it matter what I say. If you really want to make friends with her, we must investigate and screen her. Before our investigation and screening can reach a conclusion, you You can’t bring her to the mansion as a guest, do you understand?”

"That's my friend!" Osborne defended.

"I must be responsible for your life safety, Mr. Osborne. Don't forget, what did you promise me when you were in coastal defense?"

"OK, well, when can you give me an accurate answer?"

"At least a week."

"Okay, then I'll wait for you for a week." Osborne nodded, "I want to take a bath, but you don't have a bathtub here?"

"I'll have someone buy you a bathtub."

"Bathtub, what is that?"

"It's the Chinese bathtub." Luo Yao explained.

…

Tian Shoushan was in the plan, and Wen Xueren was definitely an unexpected surprise. Now, having such a gifted person in listening can help him share a lot of things.

We have to thank Wei Daming. They don't cherish talents. Otherwise, how could Wen Xueren fall into his hands? How could the meat in his mouth be spit out again?

This is not a rough statement.

Even if Wei Daming comes in person, he will not return the person. Moreover, if Wen Xueren goes back, people like Wei Daming will definitely retaliate. By then, Wen Xueren may not even have the chance to shovel coal in the boiler room. And Dai Yunong would fall out with his favorite general because of Wen Xueren?

In Dai Yunong's eyes, Wen Xueren is just a more powerful telegraph operator, nothing special. There are too many such people.

Asking for a monthly ticket!
