The secret war is silent

Ciqikou, Xiahe Street.

Old Wu's 'Old Friend' grocery store closed down due to poor management, and Old Wu also changed his identity. The Jiang family sent a servant to the mountain city to look for the young lady.

This servant cannot show up right away, and needs some planning, otherwise he will not be able to escape the military commander's investigation.

Luo Yao needed to re-select the location of the cryptographic interpretation room in Ciqikou, so he made an excuse to go to Ciqikou for inspection, which did not arouse anyone's suspicion.

If he comes out alone, he will not attract the attention of outsiders, but it will be safer.

This reason is also very good.

Gong Hui only knows that Luo Yao doesn't like people always following him behind him. The feeling of not having any privacy makes people very uncomfortable, and she does the same.

Ciqikou is not far away, so even if something happens, help can be rushed to it in time.

Make an appointment to meet at a small teahouse.

I have arranged for the person to come in, but the connection is not working yet. It's not that I can't contact him, but if I contact him deliberately, it will arouse Gong Hui's suspicion and dissatisfaction. Luo Yao said.

My identity issue has been resolved. In a few days, I will go to the radio school as a member of the Jiang family. However, due to your rules, you probably won't tell me Jiang Xiaoyu's whereabouts. Old Wu said.

This is not a big problem. The radio school will transfer the situation to my side. Although our work needs to be kept confidential, it is not to the point where we need to be isolated from the world. Luo Yaodao, I will give you feedback normally. Follow the normal review and leave approval procedures, no problem.

That's good.

If you have been here before, you can only come here less often to avoid being recognized. Luo Yao reminded.

I know, don't worry. How is her situation? Lao Wu asked.

It's okay. She needs about two months of intensive training before she can officially start working on the computer after entering the secret interpretation room. The study and training tasks in these two months are very heavy.

Then what if I need to contact you if something happens?

Find a place to live and I'll contact you.

good.

In the secret interpretation room, there is a special Chinese code deciphering team. This team is all from the research room and is specifically designed to intercept and decipher code messages in our Hongyan Village office. This team is relatively independent. At this stage, I don't know It’s easy to intervene, and the secret messages they intercept and decipher will pass through my hands, but you know, there are some situations where I can’t help it, and once the secrets are leaked, I will be suspected.”

I understand your difficulty. We will pay attention to it. As long as they can't decipher our code, it will be fine. Old Wu nodded.

Well, I have nothing else to do. You have to make your identity perfect and withstand the investigation of the military commander. Luo Yao reminded.

What do you think, after I go to the radio school and meet Jiang Xiaoyu, I go back to Jiangcheng and then come back?

This is a good idea, but is it a little dangerous?

There shouldn't be any danger. After I return to Jiangcheng, I can contact Jiang's father. In this case, if the military commander wants to investigate, he will naturally not be able to find anything negative.

This is a way. Once you get Jiang's father's explicit permission and return to the mountain city, you can stay in the name of being ordered to take care of Jiang Xiaoyu, and the contact between you will be normal. Luo Yao nodded.

That's what I thought.

Okay, let's just leave it like that. If you close this store, you'll lose a lot, right? Luo Yao asked.

The goods were dealt with cheaply, and I lost half of the money. Old Wu smiled bitterly.

Luo Yao took out a stack of money from his wallet and stuffed it into Lao Wu's hand: I'll replenish it for you, don't refuse, you need the money most now.

Okay, I'll take it and return it to you later. Old Wu took it. He really needed money. He couldn't just reach out to the organization whenever he had difficulties. The organization didn't have enough funds. If he could find a way to solve it, he should do it himself. solve.

I am leaving.

…

Where are you going? I didn't see you before dinner? In the cafeteria, Gong Hui finally called Luo Yao, walked over with the rice bowl, and sat next to him and asked.

Go to Lao Lin's place.

Has Secretary Mao finished taking the medicine again? Gong Hui asked in surprise.

Well, I also persuaded him to take less of the tiger and wolf medicine, but he didn't stop. This time I asked Lao Lin to add some warming medicine, and I think I can make up for it. Luo Yao nodded.

You men, it's true...

I'm not like that. Don't overturn a whole boat of people with one pole. Luo Yao chuckled.

I don't understand the style!

Luo Yao was busy eating, he couldn't take up this topic.

What happened to Chen Zuxun becoming a disciplinary team? He came to me today to ask for help? Gong Hui did not continue and changed the topic.

Look for a sense of presence. If he wants someone, just give it to him. Anyway, under our eyes and noses, he can't stir up much trouble.

Yeah, I know how to do it.

…

Webmaster, after a lot of comparison and analysis of the telegrams we intercepted during this period, we have deciphered the meaning of the English letters at the beginning of the telegrams, but we still have no clue about the content of the subsequent telegrams! Chi An still used to call Luo Yao Webmaster.

What's the masthead?

Date of dispatch.

That doesn't mean I didn't say it. Luo Yao couldn't help but smile bitterly when he heard this, and Chi An also smiled bitterly. After so many days of hard work, he only got such an answer, which was really frustrating.

Webmaster, I feel that there is no pattern in the following digital code. This kind of hidden spy communication usually does not use their general code book, but a specific code book. This code book is very likely It is just a book, any book can be used. As long as the sending and receiving parties agree on the encoding method, secret communication can be carried out. Only outsiders know which book they are using can they crack the code! Chi An analyzed.

Luo Yao nodded: This is also the result we least want to see, but now it seems that your analysis and guess are correct.

Then webmaster, are you going to suspend the analysis and deciphering of this type of secret messages?

Pause it. Don't waste time on this and do useless work. However, the monitoring must continue. Luo Yao ordered decisively.

Webmaster, we have been able to roughly decipher Japan's secret diplomatic messages, but we don't have any clue yet about the 'Purple Secret' they used to deliver top-secret messages. The Purple Secret is based on the Engel that the Japanese obtained from the Germans. The secret code encryption method developed by the Nigerian cipher machine. If this is calculated manually, the amount of data will be too large. With our current manpower, even if there is no error, by the time it is deciphered, their secret code will have been updated. After Chi An deciphered two Japanese diplomatic codes, he began to attack with higher-level diplomatic codes.

Don't we have the first generation of information on purple density that Osborne brought from the United States? Is this information still useful to us?

I've done some research, and it helps us understand Zi Mi's past encryption methods. At least we can understand their encryption ideas, but the complexity of the first generation Zi Mi is simply incomparable to what they use now. It's like a Compared with a staggering baby and a flying adult, the gap is huge. Chi An said with an analogy.

You know how difficult it is to get an Engeni cipher machine. It's even more difficult to get a 92-style Japanese typewriter. Lao Chi, I really can't promise you now. Luo Yao heard that Chi Ann's thoughts.

I know that the Japanese army's code books are so difficult to get, let alone the cipher machine. I can only think of other ways. Chi An sighed.

Thank you for your hard work, Lao Chi. I have something here. Take it back and look at it. Luo Yao took out a thick booklet from the drawer.

Webmaster, this is...

Chi An opened it and took a look, his eyes suddenly widened.

Is this the manufacturing principle of a cryptographic machine?

I thought about it based on the information I collected, and then conceived it through my own imagination. Lao Chi, we not only need to decipher the code, but also improve the level of our coded communication, so that we can attack and defend. That's right, our code encryption technology is not as good as Japan's! Luo Yao said.

I have long heard that the webmaster compiled a 'Romy' when he was still in the training class to use for your secret communication with the Military Command Headquarters. Now it seems that the webmaster has long been aware of our shortcomings in secret communication. Board, and is already thinking of a way. Chi An said in surprise.

First find a few people to study it and see if it can work. We can't always rely on others, and we need to build our own cryptographic machine.

I see.

This plan needs to be kept secret. Except for relevant insiders, no one else is allowed to disclose it. The information I give you can only be viewed between you. It must be filed and stored in the safe every night. Do you understand?

I understand, webmaster, but to develop a cipher machine, we need experts in mechanics and electronics, but we don't have the relevant talents now? Chi An said.

You study first, I'll find the person. Luo Yao said.

yes.

The code name for this project is Project 'L', and it is classified as top secret.

…

Li Fu was furious because he lost a lot tonight. He almost lost all the money he had won in the past few days. Although he was acting, he lost so much money at once.

Li Fu was still quite distressed.

In the same small room.

Jiang Yuan met the one-armed man, Gao Tiankui, the commander of the first battalion of the 41st Anti-aircraft Artillery Regiment.

Following Big Brother's instructions, he won twice and lost everything today. Can we start now? Jiang Yuan asked.

Gao Tiankui took a puff of his cigar and said, You first persuade him not to gamble and take him away from the casino.

Brother, why is this?

Li Fu is not an ordinary person. He is just hot-headed right now. He will get out quickly when he calms down. If you lend him money now, you will be too impatient. Gao Tiankui chuckled, We must completely lower his wariness towards you. , you have to act like you are truly doing your best for him, otherwise, when he turns around, he will suspect that you have impure motives and will be extra vigilant towards you.

I understand, brother, you are still the best. Sooner or later, Li Fu will not be able to escape from your Wuzhishan! Jiang Yuan complimented, his eyes full of flattery.
