Zhu Muyun helped Ma Yuanying fish it out, and it was reasonable for Nie Junqing to thank Zhu Muyun. Don't say that Zhu Muyun took the initiative to call to make an appointment, even if he didn't have this call, he should find an opportunity to thank Zhu Muyun. After receiving a call from Zhu Muyun, Nie Junqing immediately agreed that he would go to the appointment on time.

The box of Moutai that Zhu Muyun gave him last time has already drunk two bottles. The remaining bottles were buried by Nie Junqing. Otherwise, as long as you see it, you will definitely drink it all. I can't bear to drink such a good wine. If you have a chance, you should drink someone else's.

When Nie Junqing arrived at the dock, the dishes had been served and the wine had been arranged. Guo Chuanru's craftsmanship is naturally speechless, and it is full of color, flavor, and flavor. As for the Moutai on the table, Nie Junqing has already tasted it: the wine has a mellow body and a long aftertaste, once you drink it, you can't stop it. The reason why he was so punctual was also because he thought that he could have a good drink today.

Nie Junqing usually doesn't socialize much, which has something to do with his personality and is not good at words. At the same time, it is also related to his position. The Telecommunications Department has daily access to secrets, and he likes to be greedy, and if he doesn't choose what he says, something will happen. And Zhu Muyun is a celebrity in the Political Security Bureau, even if he says something wrong, he doesn't have to worry.

"It's a good wine." Nie Junqing sat down with wine, impatiently poured himself a glass, and as soon as he raised his neck, the wine entered his stomach. Today, he is like a different person, and he is more anxious to see wine than some men to see beauties.

"Then drink two more glasses, I've got enough wine here. You know, I'm not good at drinking, three drinks in one meal is enough. Zhu Muyun smiled and said, Nie Junqing is not smiling in the Political Security Bureau, but he didn't expect him to have such a hobby.

"My wife and brother were able to come out this time, thanks to Director Zhu's help. Junqing had nothing to repay, so he could only borrow flowers to offer Buddha, a glass of wine, and everything was in plain sight. Later, as long as there is a place to get useful, just talk. Nie Junqing picked up his wine glass and said sincerely.

"Director Nie is too polite, you and I both serve for the imperial army, and we are both people from the bureau, so we don't need to see outside." Zhu Muyun said with a smile, seeing that Nie Junqing's wine glass was empty, he poured him another glass.

"Actually, my abilities are limited, and there is nothing I can do to help you." Nie Junqing smiled, Zhu Muyun's hands and eyes were all over the sky, and he didn't seem to know anything except being able to make up passwords and break passwords. Otherwise, Ma Yuanying was arrested, and there was no need to ask Zhu Muyun to come out.

"How can I say it, Director Nie is a great intellectual, and I admire him very much." Zhu Muyun said flatteringly.

Zhu Muyun is not incapable, but he just doesn't know how to use his strengths. Nie Junqing is really dedicated to his work, and in order to avoid unnecessary trouble, he keeps a distance from others. Nie Junqing, who took off his disguise, was a drunkard.

"The most incompatible thing now is a dead reader like me." Nie Junqing said with a wry smile that the work of the telecommunications department is indeed very important, but for people like Zhu Muyun, no matter how important it is, it is useless. Moreover, because he is often in contact with secrets, he has to be vigilant at all times, even if he is in the game, he must keep a certain distance.

"Director Nie also has his own business now, how can he say that he can't get involved. The brother has a batch of goods in his hand, and he has to ask Director Nie to help him realize it. Zhu Muyun said with a smile. Nie Junqing gave full play to his strengths and let Ma Yuanying operate radios and phonographs, but he was also forced by life.

If you want to live a better life, you must have your own source of income, and you can't even eat enough with the little salary paid by the unit.

"The batch of military commanders?" Nie Junqing was stunned, Zhu Muyun was really bold, no wonder he wanted to invite himself to dinner, it turned out to be because of this matter.

"Yes, these things are a pile of scrap metal in my hands, and they can only be turned into money when they are in the hands of Director Nie." Zhu Muyun said with a smile. The Telecommunications Department is not only responsible for the radio communication between the Political Security Bureau and the outside world, but also all the telephone lines, even the lines of the Guxing Telephone Bureau, are also controlled by Nie Junqing.

"No problem, since you can afford me, it is naturally incumbent on you. Where is the stuff? Nie Junqing asked. Since it is a military command, he can also rest assured.

Zhu Muyun handed over the documents of the warehouse, and he handed over the goods to Nie Junqing, and there was no problem at all. If something goes wrong with this batch of goods in the future, Nie Junqing will be more responsible than him.

"Please, Director Nie." Zhu Muyun said solemnly.

"Well said, well said." Nie Junqing said that he was happy to help Zhu Muyun, but he added: "This batch of things can only be used for civilian use, so the price will not be too expensive." Of course, some of them will end up on the black market, but only in small amounts. ”

The only ones who were in a hurry to get this kind of thing and could afford the price were the anti-Japanese elements. If you want to make money, you have to deal with them. There is no way to do this, even Ma Yuanying's trading house will definitely have anti-Japanese elements coming and going. However, in order to make a lot of money, their presence can only be tolerated.

"I'm also doing some hard money for my brothers, as long as I have money. If the price is really ridiculously high, I don't dare to sell it. Zhu Muyun poured another glass of wine for Nie Junqing, and the more Nie Junqing drank, the happier he became.

Nie Junqing is usually cautious in his words and deeds, and he doesn't smile, but after drinking, it's like a different person. Zhu Muyun's dock, there is nothing else, but good wine and good food are enough.

For Nie Junqing, it doesn't matter if there is good food or not, as long as there is good wine. And Zhu Muyun is a very good listener, as long as Nie Junqing is willing to speak, no matter what the mountains and seas are, Zhu Muyun is willing to listen.

Zhu Muyun is a person who is good at observing words and feelings, and slapping horses. Nie Junqing, as a man, took a sip of wine, and then listened to Zhu Muyun's praise, he didn't know what his surname was.

"It's not me who blows it, the current communication password of the Political Security Bureau is all from me." Nie Junqing boasted proudly. He does have the ability to brag, and to accomplish this, it is not something that ordinary people can do.

"This kind of thing, except for Brother Nie, no one else can handle it." Zhu Muyun flattered and said that he believed that Nie Junqing was already drunk, and what he said at this time should come from the heart.

"If you change your password every three months, no one else can do it except me." Nie Junqing said smugly that he rarely said these words to outsiders before. Any man wants to get ahead and be praised by others.

However, the peculiarity of his work makes it difficult for him to talk about telecommunications work in front of others. But Zhu Muyun is different, he is a celebrity next to Li Bangfan, and he is one of the most trustworthy people in the Political Security Bureau of Li Bangfan. These words were said in front of Zhu Muyun, and they were not leaked.

"It should be difficult to change the password, others can't do it in a year, how can you do it in three months?" Zhu Muyun was surprised and said that it was not easy to compile a codebook.

Zhu Muyun was trained by Deng Xiangtao and was also proficient in sending and receiving newspapers. He had even memorized a few codebooks, but it was impossible for him to write one.

"What is this, for the sake of the communication security of the bureau, no matter how difficult it is, it must be solved. We are now law enforcers, and the military commanders have done everything they can to keep secrets. Nie Junqing said. His task was not only to keep his own secrecy, but also to decipher the other party's telegrams as much as possible.

Radio waves are easily intercepted and deciphered by the other party, so communication security is very important. As Guxing's intelligence agency, the Political Security Bureau must keep in touch with Shanghai and the following sites, and the password must be changed at any time.

"Our bureau also has an electricity supervision department, are you still afraid of the military commander's radio?" Zhu Muyun asked.

"The military commanders have been getting more and more cunning lately, and they have changed their radio pseudonyms and call signs almost every three months. Their radio stations and wavelengths are all on an active basis, and they change every time they meet. In addition to preventing eavesdropping, it can also obfuscate the public. Every four months, the header and tail translations are changed. And the implementation of the partition code book, more changes, and strict distance between the seats in each area. Recently, the military commanders have also engaged in a forced communication symbol. Nie Junqing said with a sigh. He knew all about the means of communication of the military commanders.

In addition to the initial discovery of a few military radio stations, the Electricity Supervision Section now plays more of a role in listening to illegal communications, reporting violations of discipline on the plane, and assessing the technical skills of the reporting personnel. As for listening to suspicious radio stations, it is secondary.

"What is a forced communication symbol?" Zhu Muyun asked, although he has been trained in telecommunications, he only knows how to send and receive telegrams, and is not proficient in business.

It was only after the establishment of the Electricity Supervision Section by the gendarmerie detachment that he began to pay attention to this aspect of technology. Until then, he tries to stay away from these things.

Hearing Zhu Muyun's shameless question, Nie Junqing was very proud: "This forced communication symbol is their radio station, and after it was cracked by our side, we had to contact the line." When the time comes, they will emit this forced communication symbol to imply exposure. ”

"These people are really ghosts, what can we do about it?" Zhu Muyun asked again.

"Not yet, who can crack this kind of pre-agreed code?" Nie Junqing shook his head, he also had a headache for this kind of thing, but there was no effective way.

"The current code book of the military commander also uses old books, which is even more difficult to crack." Zhu Muyun said that in the past, as long as a code book of the military commander was seized, all the radio stations on this line could be deciphered.

However, since the gendarmerie detachment and the political security bureau established the Electricity Supervision Section, the military command has also changed the original communication secrecy system. At present, the code books of the military command are all used books that can be purchased in any bookstore, and some fragments are extracted from them, such as dozens of pages in the front and dozens of pages in the middle, which are temporarily compiled as code books. When enabled, add or subtract ordinary code to become a unique codebook.

When the radio station is set up, the operator no longer has to carry a code book, as long as he tells him in advance which old book to use, and then makes an appointment to decode it. The code books between each radio station are different from each other, and even if someone is wrecked, it will not implicate other radio stations.
