The secret war is silent

Luo Yao didn't close his eyes all day and night. He slept until dawn, and he also slept through the Lantern Festival. When he opened his eyes, it was already the sixteenth day of the first lunar month.

Open the windows and let the chilly early spring breeze blow in.

Cleared my mind.

I feel like my energy is back.

Dong Dong...

There was a knock on the door.

Come in! Luo Yao still lives on the third floor. Anyway, he is going back to Jiangcheng soon and has no plans to move out until he comes back.

Luo Yao was a little surprised when he saw Osborne and Chi An walking in together. It was the first time that these two people came to see him together.

Counsellor Osborne, Deputy Director Chi (deputy team leader), you two came here early in the morning. You must have something important to ask me for? Luo Yao greeted him with a smile, Quick, please come in and sit down.

Thank you. The two of them thanked each other, one sat on the chair, and the other sat down casually next to Luo Yao's bed.

Come, drink water, drink water. Luo Yao poured a glass of water for each of them.

Group Luo, Consultant Osborne and I came to you to report to you on the idea of ​​deciphering the code of Japan's secret radio station in the mountain city. Chi An said first.

Okay, do you already have an idea? Luo Yao said in surprise.

Yes, through our statistical and comparative research on the Japanese military secret code and the Japanese Ministry of Foreign Affairs diplomatic code, we have discovered some situations that will help us decipher the Japanese military secret code. At least we can decipher a specific code. . Chi An said.

Deputy leader Chi is right. We suspect that the Japanese army's code uses English letters to spell out Japanese pronunciations. If this assumption is true, then this kind of code belongs to 'rational spelling'. For this kind of 'rational spelling' The passwords can be associated and analogized, which makes it easier for us to decipher them, Osborne added.

Consultant Osborne is right. As long as we make statistics based on Japanese grammar and idioms, and analyze specific messages, we can try to decipher a specific message. For example, at the beginning of the Luo Group It requires us to start with a specific encrypted message first, which is a very correct decision. Chi An said.

Well, keep talking.

Luo, you are a genius decipherer. You immediately found the right direction for us. Otherwise, we would probably have spent a lot of time without achieving results. Osborne was not stingy with his praise for Luo Yao.

For information on meteorological conditions, especially for lurking stations, it is impossible for them to use Engel cipher machines for encryption, so we don't have to worry about them constantly changing the order of encryption, because they use The fixed code book brings convenience to our deciphering. The words and sentences used in meteorological information are very limited, and the information basically has a certain format. We can identify this through comparison. In fact, The team has already helped us finish the work, which can be said to have saved us a lot of comparison and statistical work... Chi An continued to continue Osborne's words.

Luo Yao nodded frequently. He had indeed helped them do the preliminary work, and why did he let Chi An continue to do it? Because Chi An had an in-depth study of Japanese grammar, which he could not match. To decipher Japanese telegrams, someone like him is needed.

For example, in a message about the weather information of a mountain city, which word appears most frequently? For example, if we compare the weather data of the mountain city with the weather conditions on the day when the Japanese planes bombed Chongqing, we find that scrape Category 4 winds are the most common.

So in these messages, the two English letters that appear most frequently represent the word four, which of course may be the Arabic numeral 4, and the word after it may be the word level.

In this way, by following the clues, from word to word, you can basically figure out the general content of a telegram.

Wei Daming had previously engaged in deciphering Chinese secret messages, which was completely different from this. Therefore, these messages were lying in the Special Technology Research Laboratory, but they had not been deciphered.

But this is piecemeal. If you want to decipher it systematically, you still have to do a lot of work, but it will never change. It also involves a lot of statistics and calculations, as well as the research and analysis of Japanese grammar.

Deputy Team Leader Chi, Consultant Osborne, now that we have an idea, let's follow this idea. No matter whether we can decipher it or not, as long as the idea is correct, we can always decipher it.

It's better that you, Team Leader Luo, looked in this direction. The clouds and mist have cleared away and the sky is clear!

I'm just proposing an idea. It's up to you to do it. Luo Yao said hurriedly. At this stage, there are no auxiliary calculation tools to decipher the code, so it can only be done manually.

Luo Yao did this in many ways, not only to achieve results as quickly as possible, but also to accurately grasp the bombing of the mountain city by Japanese planes and prepare in advance, thereby reducing the casualties of the common people.

People are the foundation of everything.

There is a direction and a method. Now we just need to move in this direction.

Chi An and the others are very motivated.

If the code can be deciphered within a few days, it will be a great achievement, especially for Chi An, who has not made any achievements since he entered this industry ignorantly, and he is unwilling to accept it.

Now, I finally have a chance to achieve results, so why not work hard?

At the same time, he also realized the importance of an excellent team. In the past, they didn't have people or financial support, but why couldn't they achieve results?

Isn’t it a team?

Especially when it comes to leaders, Team Leader Luo, despite his young age, is knowledgeable and can help you find the right direction.

Under him, you only need to work hard, and you don't have to worry about anything else. You will have all the fame and profit.

Especially the free and relaxed working atmosphere here makes Chi An feel like a fish in water. Even working at China Central Radio Station, there are various personnel situations, which are sometimes very troublesome. The bureaucratic system is rigid and incompetent. If it wasn't for the sake of fighting the war and saving the country, he would have stopped wanting to do it.

After breakfast, Luo Yao also joined in the work.

Now that there is one more person and more power, the speed of analysis and deciphering will naturally be accelerated.

In addition to the respective division of labor and responsibilities, continuous discussions, demonstrations, and brainstorming are also required to ensure that there are fewer mistakes.

This can really be regarded as working around the clock and forgetting to eat and sleep.

Chi An didn't go to work at the radio station for several days in a row. As a result, people were unhappy and came to visit him. Chi An simply quit his job.

But for a while, they couldn't find anyone to take over. Mrs. Chi's health was obviously much better, so she took over for him for a few days and waited until she found someone to come back.

The child was sent to the mansion and given to Xia Fei to look after. Anyway, he was neither hungry nor thirsty. The food was better than at home, so the child was not happy to go home.

Where is the candy at home to eat freely and play with him?

Two days later, a complete telegram was finally deciphered word by word using a piecemeal method. Although there were only a dozen words, it was of great significance.

January 16th, light rain, northwest wind level 3, temperature -1℃-5℃, heavy fog, humidity 85%, visibility 50 meters.

Once this is deciphered, the rest will be easy to decipher.

Just compare.

It was quickly deciphered.

Of course, there are also some cables that cannot be deciphered, and even the translations are completely incorrect. These cables obviously do not talk about weather-related intelligence information.

It's normal to make a wrong conclusion. If it's not bad, it would be too sensational. Even so, Chi An admires Luo Yao endlessly.

The ability to filter out these messages, especially those that have not yet been deciphered, to find similarities and merge similar items is really amazing.

If it were him, he would have to sort them out from tens of thousands of secret messages. If he could achieve an accuracy of more than half, he would be a winner.

And Luo Yao actually reached an astonishing over 90%.

In addition to the weather information sent by the latent radio station, there was also a call back from the Japanese aviation unit, and then compared with the timetable of the bombing of the mountain city.

The reply from the Japanese army can be roughly deciphered.

This is because the Japanese army needs to make air raid plans based on the relevant weather information sent back from the lurking mountain city. And whether to conduct an air raid, they must notify the lurking radio station in the mountain city to avoid accidental damage. If they are bombing a specific target, the Japanese who lurk in the mountain city are even more needed. Agents provide guidance on the ground.

Finally, we have achieved results. Now we are waiting to intercept the message for verification. Luo Yao announced, Everyone has hardly slept in the past two days. Now we all go back to have a rest. We will do the rest of the work after we have rested. .”

Team Luo, so many telegrams have been verified, so they are probably correct. Shouldn't we report them to the superiors?

Don't worry, the report is certain, and your contribution is indispensable. However, our purpose of deciphering the Japanese military code communication is to prevent and provide intelligence support to the soldiers on the front line. Therefore, it is useless to just decipher the past messages. The important thing is We can decipher future messages, so this can only be a phased achievement. We must guard against impatience and arrogance and continue to overcome difficulties!

Group Luo, if we want to systematically decipher the Japanese military secret code, we may need a large number of samples, and we need to establish a listening radio station closer. The mountain city is too remote. If it can be established in Xiangcheng or the southeast coast A listening station would be even better, Chi An suggested.

Deputy Leader Chi, you are talking about the future. It is difficult for us to do it now with our strength, but we can cooperate with the various districts and intelligence stations under the military command and let them transfer the intercepted Japanese military secret messages or the code book-related information they obtained. Send it here and let us study it, Luo Yao said.

That's okay too.

Let's all go back and rest. We've all stayed up all night.

Everyone dispersed, and the office on the second floor suddenly became empty.

Luo Yao made a phone call to Mao Qiwu, briefly talked about the progress of the secret research team's work, and asked Mao Qiwu to ask Dai Yunong for instructions, and he would report the relevant situation in person.

The secret research team deciphered the message sent by the Japanese army's lurking radio station in the mountain city. This was no small matter. Mao Qiwu reported to Dai Yunong immediately.
