The Black Room was a secret code deciphering organization established by the Zhengfu of Chongqing during the Anti-Japanese War. It was specifically responsible for the military command. During the Anti-Japanese War, it deciphered a large number of enemy telegrams and made outstanding contributions to the victory of the Anti-Japanese War.
In recent times, the Japanese army has frequently changed passwords, sometimes even in less than a day. The black room has no way to deal with such a speed of change. They can't figure out how the Japanese army can do it in such a short time.
Within a certain period of time, the password will be reset.
You must know that compiling a password is an extremely complex task that requires many professionals to spend a lot of energy to complete it. It is completely impossible to change it in two days. Even if a new password is changed, how to send the new password book to
The units that need to be used are definitely not able to do it in a short time. For example, if the Japanese army compiled a code in Shanghai, it would be impossible for the new code book to be sent to Chongqing within ten and a half days.
The black room also guessed that the Japanese army must have a new password system, but they couldn't figure it out.
They were worried about this. Xu Dalong was able to decipher the Japanese military bombing of Chongqing, which shocked the black room. They hurriedly asked the uniform committee to send an invitation to Xu Dalong to guide the deciphering work.
The Committee was also troubled by the inability to decipher the Japanese army's messages, and they were very interested in the black room's suggestions. They knew that the military command had a close relationship with Xu Dalong and had contact information, so they called the boss and asked him to give
Xu Dalong sent a telegram asking him to arrive in Chongqing as soon as possible to participate in the code-breaking work of the black room.
The boss did not dare to neglect, so he sent a telegram to Xu Dalong on the same day.
In order to gain time, Xu Dalong set off overnight to Chongqing.
When he came to Chongqing this time, he took a transport plane from Zhongtiao Mountain to northern Shaanxi, and then flew directly from northern Shaanxi to Chongqing. After arriving at spb airport, when Xu Dalong got off the plane, he saw several cars parked at the airport, and some people greeted him.
Deputy Director Wang of the Equalization Committee and the boss of the military command also came in person, as well as a lieutenant general from the Guo Army and several officials in plainclothes.
Seeing Xu Dalong get off the plane, everyone came forward to greet him. Deputy Director Wang first greeted Xu Dalong cordially, and then the boss.
Xu Dalong didn't know the others, so Deputy Director Wang introduced their identities. Xiao Na was the director of the black room, and several other people were important members of the black room.
Xu Dalong shook hands with them and said hello, and then everyone got on the bus. Under the escort of two trucks full of armed guards, they entered the city and arrived at the reception area of the Equal Affairs Committee.
The reception building has only two floors. It looks ordinary from the outside, but the decoration inside is very luxurious.
The banquet was very sumptuous. At the banquet, Deputy Director Wang gave a welcome speech on behalf of Guofu, and Xiao Na expressed welcome on behalf of the Black Room and spoke a few words. Everyone was very polite to Xu Dalong, and the atmosphere of the banquet was very harmonious.
After the banquet, Deputy Director Wang invited Xu Dalong to the reception desk of the Military Commission. The boss invited Xu Dalong to his mansion. Xiao Na also invited Xu Dalong to the reception desk in the black room, but Xu Dalong declined them all.
Xu Dalong still had his own things to do. He definitely couldn't live in these places. It was equivalent to being under the surveillance of the enemy and he couldn't do anything. He proposed to return to the Military Command and live at his father-in-law's house.
Xiao Na felt a little embarrassed, because the Black Room is a highly confidential unit of Guofu, and Xu Dalong is now involved in the work of the Black Room, so his whereabouts should also be highly confidential, so he hopes that Xu Dalong will live in the reception office of the Black Room
.
Seeing Xu Dalong's refusal, he turned to Deputy Director Wang and the boss of Juntong for help.
Deputy Director Wang believed that Xu Dalong would never reveal the secret. Seeing Xiao Na's look for help, he smiled and shook his head.
The boss said directly: "There is no need. Brother Dalong can go wherever he wants. When you want to go to the black room to work, you can make an appointment in advance."
Everyone arrived in front of the hotel. Deputy Director Wang, the boss and Xiao Na all had their own cars. Xu Dalong got into the boss's car and asked him to take him to the family home of the Military Command Department.
When we arrived at the gate of Lin Mansion, the boss got out of the car and said to Xu Dalong: "Brother Dalong, you go to bed early, brother, I won't go in."
Xu Dalong nodded, and then watched the boss's car leave. After the boss left, one of the two military cars that escorted them escorted the boss away, and the other one stopped at the door of Lin Mansion.
Xu Dalong walked over and patted the car door. The door opened and a military commander walked out with a smile on his face.
He asked: "Sir Xu, what are your orders?"
Xu Dalong said unhappily: "What are you doing here? Go back."
The military commander said with some embarrassment: "Sir Xu, in this humble position, I am ordered to protect your safety."
Xu Dalong said unhappily: "Okay, I don't need your protection, just go back."
Seeing that the military commander was still hesitant, Xu Dalong said: "Okay, stop talking nonsense and leave quickly. I'll call your boss later and don't allow anyone to follow my car again."
The military commander knew about Xu Dalong's relationship with his boss and did not dare to disobey him. He saluted Xu Dalong, then got in the car and left.
After the military reunification agents returned to the headquarters, they called their boss's mansion and reported to him that Xu Dalong refused to allow them to protect him.
The boss said: "Since he said so, you should ignore this matter in the future. It is best not to appear in front of him to avoid misunderstandings."
When Xu Dalong came to Chongqing this time, he only brought Wei Dayong and two special forces members. He wanted to get in touch with the underground party. It was inconvenient for him, Wei Dayong, and his two personal followers to come forward. Xu Dalong had already informed Chu Yun'er in advance
She sent a telegram and transferred several special operations team members from her. Before Xu Dalong arrived in Chongqing, he had quietly entered the CQ city. These people were all new to the agents of the Military Command and the Central Command, and they were looking for information.
They are responsible for the matter.
Regarding the matter of finding the underground party liaison group, Xu Dalong has been delayed for several days, and his superiors are also pressing hard. After arriving in Chongqing, he did not dare to delay for a moment, and took the time to get in touch with the special operations team members.
Xu Dalong didn't know whether a bug was installed in Minister Lin's home. Although he believed that Minister Lin held a high position, whether he was the military commander or the central commander, in order to avoid trouble, there was a high probability that a bug would not be installed in his home. Moreover, Xu Dalong
Their identities are also very special, so the possibility of them installing eavesdropping devices is even smaller.
But he still didn't dare to take risks. Instead of using the home phone, he carried a radio with him in the car.
The military commander knew that Xu Dalong was a military commander and had many matters to deal with. It was normal for him to use the radio station, and the government could not interfere. However, his use of the radio station was public and had signals, so it was easy to be targeted. If there was Chongqing,
The radio station contacted him, and it was easy for him to be targeted by the secret service.
Although Xu Dalong is not afraid, those who work underground in Chongqing cannot be discovered by the spies, otherwise they will be annihilated. Therefore, the most difficult thing for Xu Dalong is how to get in touch with the underground party in Chongqing.
Xu Dalong thought about it and finally thought of a way.
Early the next morning, the Black Room called and said they would send someone to pick up Xu Dalong.
Xu Dalong did not let them come over. He only asked them to tell them the address, and after making an appointment for their arrival, he and Monk Wei drove the Lin family's car to the dark room.
On the way to the black room, Monk Wei was driving in front, and Xu Dalong sent the telegram. He planned to use this method to communicate with radio stations during his stay in Chongqing. It is difficult to lock a moving radio station.
Ding Baohang is the squad leader of the special operations team and was ordered to protect Chu Yun'er in the Guanglong Gold Mine. He received orders from Xu Dalong and brought a radio station and several special forces members to Chongqing. His main task was to serve as Xu Dalong's liaison officer.
Find underground party contact groups.
They are new faces and will not attract attention, but their actions are also very dangerous. Once the secret service discovers their underground party identities, even Xu Dalong will not be able to protect them.
Xu Dalong had told them this in advance, but they still faithfully carried out Xu Dalong's order and came to Chongqing to carry out this dangerous mission.
After receiving the telegram from Xu Dalong, Ding Baohang went to find the contact person of the liaison group and tried to get in touch with the seven-member group.
After the conversation was divided, Xu Dalong came to the black room.
The guards had been notified in advance, and when they saw Xu Dalong's license plate number, they opened the gate and let his car enter the yard.
Xu Dalong saw Xiao Na already waiting in front of the office building.
He saw that in addition to the two experts he met last time, there were two foreigners.
After Xu Dalong got out of the car, Xiaona came up to him, shook hands with him cordially, and said hello. The two foreigners looked at Xu Dalong with curious eyes.
Shawna said: "Captain Xu, let me introduce to you. This is Mr. Braun, an internationally renowned cryptography expert."
Xu Dalong stepped forward, shook hands with him, and said in fluent French: "Mr. Braun, I have heard of your name for a long time. It is a great honor to meet you."
Braun was surprised to hear that Xu Dalong could speak fluent French.
He sincerely praised: "Mr. Xu, I have heard of your name a long time ago. You are an amazing young man. I didn't expect that you can speak such fluent French. It's really amazing."
Seeing Xu Dalong greeting Braun in French, Xiaona and others also showed surprise in their eyes. They were not only surprised that Xu Dalong could speak French, but also wondered how he knew that Braun was French.
.
Braun was invited by the military commander to come to the black room to engage in deciphering work. This is a highly confidential matter for the military commander. Only a few people know about it except those inside the black room. Now they all doubt what it is.
People leaked the news.
In fact, this is a very common thing for Xu Dalong, because the records about the black room will be public information in later generations. It is extremely common for Xu Dalong to know Braun's existence and his identity.
Next, Xiaona introduced Braun's assistant, Xu Dalong also greeted him, and then everyone walked into the black room conference room.
There are already many cryptography experts from the black room sitting in the conference room, dozens of them. These people belong to different groups and are responsible for part of the code-breaking work. Braun is responsible for summarizing.
Seeing Xu Dalong walking in, everyone stood up and applauded out of politeness, but the applause was sparse. It was obvious that they were skeptical about Xu Dalong's ability to decipher the code.
Xu Dalong is famous. These people have heard of it and respect him, but they only respect him as an excellent military commander. Professional things like deciphering codes are everyone's strengths. They absolutely do not believe that Xu Dalong is there.
What other useful help can these aspects provide them?
Xiao Na introduced Xu Dalong's identity, Xu Dalong also greeted everyone, and then everyone sat down.
Xiao Na said: "Captain Xu is a rare talent, and I won't go into details about other deeds. He is unique in deciphering codes. Now I would like to invite Captain Xu to speak to you."
After he finished speaking, he took the lead in applauding, and everyone clapped politely. The applause was much sparser than the one just now.
Xu Dalong knows very well that these experts here are top talents and have inherent arrogance. It is useless to say anything else. Only if you can defeat them professionally will they respect you.
Xu Dalong didn't want to talk nonsense and asked directly: "Everyone, what bottlenecks have been encountered in the code-breaking work of the black room?"
These experts are all people who do practical things. What they hate most is when others talk nonsense and talk nonsense that sounds big and empty. Seeing Xu Dalong's approach of going straight to the topic, I developed a good impression of him.
When Xiaona heard Xu Dalong being so straightforward, he said: "Deputy Team Leader Peng, please introduce the current status of code deciphering to Captain Xu."
Peng Fei is the deputy leader of the cryptography team, responsible for specific work arrangements and summarizing the progress of each team.
He said: "The Japanese army now changes their codes very frequently. During major battles, they sometimes even change them once a day. The number of Japanese military messages that the black room can obtain is very small and cannot be used as a reference. In such a short period of time, it is difficult to complete the deciphering work.
.
Not only that, even if a message from the Japanese army could be deciphered, the Japanese army quickly changed the code, and the deciphered message would have no reference value."
Xu Dalong is well aware of the process of formulating and deciphering the development of codes during World War II. He said: "The only possibility for the Japanese army to change codes so quickly is that they used a cipher machine to compile codes, so they could change codes quickly. They also
On the basis of the cipher machine, a key machine is used."
Xu Dalong's words shocked everyone. None of the experts expected that Xu Dalong was so professional and immediately revealed the key to the problem.
