"At the docks? It's not safe here. Zhou Lin said in surprise.

"It's not safe at the gendarmerie command either." Kobayashi said.

Zhou Lin was right when he thought about it, this place must be the target that all forces have spent a lot of effort to find. You are in the gendarmerie headquarters, and it is difficult to guarantee that there is no hidden line of the enemy.

The only way to do this is to find a place where people won't notice, that's the safest.

Take the wharf as an example, without the strength of a single regiment, it will not be able to rush into the wharf.

This one, do not worry about the enemy's surprise attack.

In addition, there are many buildings in the docks, and many of them are secret warehouses and the like, and there are soldiers standing guard for protection, and the enemy does not know what is going on inside.

Besides, the enemy would have thought that such an important unit would be put on a dock with a mixed flow of people?

In their impression, the black room should be in an airtight place of defense.

Yamada's hand is very clever, only he knows about the dock, and no one else knows, the chance of leakage is small, and he must find himself if something happens.

"Where?" Zhou Lin had no choice but to accept it.

"The ghost building three hundred meters behind your small building."

Zhou Lin's eyes widened: "It's too desolate there!" It's a haunted building. ”

"The chief said that ghosts are afraid of wicked people, and as long as we go in, ghosts will be afraid of moving." Xiao Lin said stiffly.

"Okay, you're amazing! Do you want to send you to the town now? ”

"Don't talk about irrelevant things." Kobayashi pretended to be a decent man and a gentleman.

"Good! Talking about business," Zhou Lin immediately got serious

"The name of the black room is the Codebreaking Division, and you are also the Chief of the Codebreaking Division." Xiao Lin said proudly, "You're going into that haunted house." ”

Zhou Lin shuddered: "I applied to the head of the agency for a land exchange." ”

"It's useless! The director took a fancy to the gloomy and quiet place. Only such a place can be used as a black room. ”

"Then I will resign from this position as director, and now I have too many positions on me. I can't be busy, you see, the director of the Exit and Entry Administration, the deputy director, the leader of the fifth group, plus the director of the code-breaking department, then I won't be crushed. ”

"If you have the ability, you can call the director and talk to him to see if he sympathizes with you." Xiao Lin crooked his mouth and hinted at the phone.

Zhou Lin softened and stopped talking, seeing that Xiao Lin was very proud.

"Where did the people in the Password Division come from?" Zhou Lin asked.

"The head of the agency will draw from the telecommunications office of the secret service, the telecommunications office of No. 76, and the telecommunications office of the gendarmerie headquarters to form this cipher office. Oh! This is also the Telecommunications Division of your Immigration Department. ”

"Can these people make it happen? They've been doing this for two years, and if they have results, they'll have already made them. Zhou Lin looked down on these people.

"Just because they didn't work now doesn't mean they can't now. In the past, they did not have a core, but now that Wu Mingtao is here, they will form an effective team with Wu Mingtao as the core. ”

Zhou Lin thought of a question: "How does Wu Mingtao arrange it?" ”

"Give him the title of chief decipherman, administratively with the rank of deputy director, and give him the rank of lieutenant colonel of the Peace Army." Kobayashi told all the arrangements.

"Then I'll arrange a construction team tomorrow to decorate that small courtyard." Zhou Lin said.

Xiao Lin smiled, he thought that Zhou Lin was afraid of ghosts and went to renovate the small courtyard.

"The head of the agency is asking people to design the drawings, and then you can take the drawings and go to the decoration."

Zhou Lin thought about it, let's wait for the drawings! Maybe there will be a big construction.

sent Xiao Lin away, and Zhou Lin told Xiangjun the news as soon as possible.

If the enemy has a dark room, then the secret communication of the organization is dangerous.

Xiangjun asked worriedly: "Will our password be ......?"

Zhou Lin: "It depends on Wu Mingtao's ability, if he has two hands, then our radio station will be in danger." No, you have to ask the central government. ”

Xiangjun asked Zhou Lin to pick up the telegram draft, then memorized it, and then burned the telegram draft.

Xiangjun went out at the same time as Zhou Lin, she went to the theater, and Zhou Lin went to the tea house.

When Zhou Lin told Yang Kun this information, Yang Kun was also a little anxious.

He immediately went to report to Dai Li, and Dai Li, who received the telegram, was so angry that he really wanted to go to the Military Commission to beat up those people.

Such a cryptographic genius did not give full play to his expertise and serve the Anti-Japanese War, but he squeezed out, suppressed, and labeled people as Japanese lackeys, and as a result, people have really become Japanese lackeys now.

However, Dai Li is just angry, if he were one of those people, it is estimated that he will also play these tricks. The War of Resistance is important, and one's own position is even more important.

Now it's a question of how to remedy it, and quickly.

First of all, Yang Kun's radio station must be encrypted, some secrets there cannot be cracked by the enemy, as long as Yang Kun's password is cracked, then the opportunity for Zhou Lin to be exposed is not far away.

Secondly, the password of the military commander Pearl Station should also be encrypted.

Finally, there are other units and personnel of Mingzhu, and this matter is not easy to say.

Now only Zhou Lin knows that this institution has been established, as long as the matter of the Pearl Black Room is announced, then Yamada will know who it is.

Therefore, people from other units can only be notified after the black room is officially operational.

But the military commander has the advantage of finding someone to design the code in advance to prevent the black room from being deciphered.

Dai Li asked someone to discuss how to prevent decipherment.

In the end, it was decided that Yang Kun's radio station would use the most primitive method.

It is to use a book as a password, and each party holds one for each party.

This method made it more difficult for the person who compiled the telegram, but as long as the enemy did not have his hands on the book, then it was impossible for him to decipher the code.

Even if the enemy had this book, it could have been prevented.

That's multiplication, multiplication, subtraction. For example, according to the daily portion of A, B, C, D, 10 days of dry, the corresponding increase and decrease of the number: day A is the yang stem plus the number 1, and the code number of this day is added 1. Day B is dry minus 2, and the code digits on this day are minus 2.

In terms of book selection, you can't choose a popular book on the market, preferably a book from five years ago.

When Dai Li encrypts Yang Kun's electrical energy in accordance with this requirement, the possibility of Yang Kun's radio station exposure is greatly reduced.

When Yang Kun told Zhou Lin about this method, Zhou Lin was reassured. Zhou Lin was pleasantly surprised.

He thought of Sister-in-law's radio station, the most important radio station.

So, Li Ziqiang passed Zhou Lin's report to Yan'an.

Yan'an added another secret on the basis of Yang Kun's password, and added it to the heavenly stem of the moon, which made it more secure.

After dealing with the problem of the radio station, Zhou Lin didn't have to worry about it.

At this time, Yamada brought the drawings, and Zhou Lin invited the construction personnel to carry out the construction.

Among the construction personnel, people sent by Yan'an were among them, and they did their tricks in the construction.

There's an oversized bug buried inside, which Smith provided.

In addition, the bugging device is connected to an underground power line for power supply operation.

In Zhou Lin's home, you can receive the sound transmission of the eavesdropping device. Please Baidu "Throw Book Network" Thank you for your support!
