Cooperate with American cryptographic expert Herbert Yardley to detect the Chongqing spy case?
Brother, stop joking with me, he should be the one cooperating with me to solve the case, right?
However, this Yardley really has two skills. As soon as he came to China, the government selected 30 students to follow Yardley to learn how to decipher codes, and the embryonic form of the "Chinese Black Room" was established.
The "China Black Room" deciphering personnel work from 8 a.m. to 12 noon, 2 p.m. to 6 p.m., and 7 p.m. to 10 p.m. every day. The monthly salary is 30 yuan in French currency, and each person also has to pay 5 yuan for food.
In addition to learning Morse code, which is unified around the world, code breakers also need to understand a large number of program codes that represent the forty-eight Japanese equivalent of Japanese alphabet kana. The daily learning tasks are boring and arduous.
Of course, the name "Chinese Black Room" would not officially appear until two years later.
It was Yardley and his trainees who were the first to discover that the Chinese air defense force intelligence might be leaked.
At that time, black room monitoring personnel would intercept some secret messages at 6 a.m., 12 noon and 6 p.m. every day.
Yeardley discovered that these coded telegrams only used 10 Japanese letters, but Japanese has 48 letters. What can only 10 letters mean?
He guessed that these 10 pseudonyms might be used to represent numbers, and immediately analyzed the 8 telegrams intercepted within a few days.
The headers of the eight telegrams were all "027". Yardley guessed that this probably meant that the telegrams were sent from Chongqing.
The first three messages were sent at 6 a.m. on different days, and the second set of numbers were all "231." Based on this, it is speculated that 231 probably refers to 6 a.m.
Based on this speculation, the second group of numbers "248" in messages No. 4, 5, and 6 represents 12 noon; the second group of numbers "267" in messages No. 7 and 8 represents 6pm.
The eight messages are all the same length, and the third group of numbers all start with 4. Yardley speculates that this part should provide meteorological information about the Chongqing area, such as weather, cloud height, air pressure, temperature, and visibility. , wind direction and other information.
Except for the sixth message, which is 401, the third group of numbers in the eight messages is 459. It had been raining lightly for a few days in Chongqing. Based on this, Yardley speculated that 459 should refer to rainy days, while 401 means sunny days.
However, after the Japanese spies were executed, eavesdroppers successively intercepted a batch of secret messages, and the deciphering work has not yet been completed.
Subsequently, the Japanese army dispatched fighter jets one after another and caused bombing tragedies in Chongqing.
The tragedy deeply shocked Yeardley, who blamed himself for not catching the spies who provided intelligence for the Japanese planes in time. He vowed to catch the mastermind hiding behind the scenes.
However, until December, the spy was still at large.
The task that Meng Shaoyuan received was to fully assist Yardley in capturing this deeply hidden spy.
The question is, is Master Meng willing to help others?
He knew who the spy was and who his accomplice was.
I just can't say it out loud.
However, since Dai Li personally confessed the matter, he did not dare to neglect it. After coming out of Dai Li's office, Meng Shaoyuan went straight to the "China Black Room" without stopping.
Everyone standing guard at the door knew Section Chief Meng, and no one dared to stop him and just invited him in.
However, Master Meng was still very dissatisfied and gave him a lesson about standing guard. The general meaning was that anyone who came would be subject to strict interrogation and so on.
The guard looked obedient on the outside, but he was disdainful in his heart.
If you really do this, given your character as Section Chief Meng, will you not retaliate? If you offend Director Dai, the worst possible outcome is that family law will be enforced, but if you offend you, Chief Meng, it will be a life-threatening situation.
As soon as he entered, he saw his old friend Wei Daming constantly exchanging opinions with a foreigner.
The two seemed very nervous, spoke very fast, and even had some heated arguments.
"Old Wei!" Meng Shaoyuan greeted him carelessly.
"Hey, asshole, shut up!"
Unexpectedly, the foreigner yelled angrily.
Holy shit!
Is this Yardley?
How dare you call yourself a bastard?
Meng Shaoyuan's nose was so angry that he was crooked.
When Wei Daming saw that it was Meng Shaoyuan, he probably wanted to ease the tense atmosphere: "Mr. Yardley, take a break. Let me introduce you. This is Mr. Meng Shaoyuan, the chief of the Operations Section of the Military Command Bureau. He is We, Deputy Director Dai, sent us to help us solve the case."
Unexpectedly, Yardley would dismiss it at all: "What I need is someone who can help with the code, not a damn secret agent!"
I’ll rely on you again!
This foreigner is so angry!
Wei Daming's expression changed a little. He and Meng Shaoyuan had been colleagues since Nanjing, and he knew this man's character very well.
Yardley didn't know the meaning. He first yelled at Meng Shaoyuan, and then called him a "damn secret agent"?
Who offended him? When Master Meng gets angry, who cares who you are? No one will be able to bear the responsibility if a big mess happens.
Meng Shaoyuan was really angry. Normally, he would have had an attack a long time ago.
But then I thought about it again, forget it, the establishment of the "Chinese Black Room" was the foundation laid by others, which allowed China's encryption code deciphering work to quickly integrate with the world's advanced level and avoid a lot of detours.
After all, they have made an indelible contribution to China's Anti-Japanese War.
Besides, the investigation of the Japanese espionage case has now reached a dead end, and it is inevitable that Yardley will be upset and angry.
Forget it.
I count you as my sister!
There is no need for retaliation, but if I don't show my hands in front of you, you really don't know how many eyes Lord Ma has?
Originally, Meng Shaoyuan knew that although Yardley was temporarily in trouble, he would soon be able to find a way to decipher the code, and he did not want to take credit from others.
But now it’s no longer possible, yelling and calling yourself “damn”?
Yardley, Yardley, you don’t understand, Master Meng, in my own time, I looked at the "Chongqing Air Defense Spy" case very carefully, and even discussed it with my good friend Xiao Yan. Lee was full of praise.
I understand every detail clearly.
I have to give you a warning.
Meng Shaoyuan looked unconcerned and said in fluent English: "Mr. Herbert Yardley, I have been ordered to assist you. I hope we can have a happy cooperation. Lao Dai, how is the deciphering work going? ?”
"It didn't go well." Wei Daming didn't hide anything: "Mr. Yardley, this Mr. Meng is very capable. Can I tell him our discussion?"
Yardley snorted, noncommittal.
Wei Daming picked up a stack of research materials: "For example, the newly intercepted secret messages we intercepted yesterday and this morning were all a group of four numbers, such as 1349, 5727, and 7234. The passwords change every day and there are no rules. The only thing we found The characteristic is that the first group of each telegram is five English letters that cannot form a word, such as mifto, lofed, titth, etc."
"May I see it?"
Meng Shaoyuan took the information from Wei Daming and pretended to read it for a while: "It's not difficult."
"What?" Wei Daming and Yardley exclaimed at the same time.
Not difficult?
Are you kidding me?
Irregular secret messages, don’t you think it’s difficult?
You know, Yardley is the leading cipher code expert in the United States, and Wei Daming is China's telecommunications genius.
The two of them had been studying for so long and had no clue.
Isn’t it difficult for someone to suddenly come out and say something now?
"Look." Meng Shaoyuan held the information seriously: "The first group in this intercepted telegram is the five letters 'ewwee'. If my judgment is correct, 'ee' refers to the 11th. This telegram is It was intercepted yesterday, so yesterday happened to be the 11th."
Yardley thought for a while, then snatched the materials from Meng Shaoyuan's hand, took the pen, and kept writing something there.
After almost half an hour, he suddenly looked up, with ecstasy written on his face: "Meng, genius, you are a genius! Yes, it is like this, it is like this. You see, according to this idea, the deciphered The result of rearranging the letters according to the single sounds is, her (her), light (light), grain (grain)!"
Wei Daming was always paying attention.
Yes, that's true.
Yardley then said to himself: "She, light, grain? What does this mean?"
Unexpected?
Forget it.
"!" Meng Shaoyuan said it for him: "With this new type of password that changes every day, the secret list is probably an English book. If you can find this book, you can follow the clues to find the spy behind the scenes."
"right,!"
Yardley reacted immediately. He looked at Meng Shaoyuan in disbelief: "Do you also know the secret code?"
"A little research, a little research." Meng Shaoyuan looked humble.
Yardley's attitude towards Meng Shaoyuan completely changed.
He likes his peers in this business.
Especially a fellow genius like the young man in front of me!
Wei Daming felt very strange.
He had known Meng Shaoyuan since Nanjing, but he had never heard of him doing any in-depth research on cryptographic codes?
Why was it suddenly possible to decipher the Japanese top-secret code so quickly?
Ah, right.
Wei Daming suddenly realized.
Although Meng Shaoyuan did not understand cipher codes, he was definitely a good hand in intelligence work. His telecommunications office received so many Japanese cipher codes, all of which were provided by him.
He must have obtained the secret code used by the Japanese in Chongqing through other channels, and then pretended to be a ghost in front of Yardley.
Wei Daming smiled slightly and did not expose him. As long as Meng Shaoyuan doesn't get into trouble.
"Mr. Yardley, we can confirm that this is a book." Meng Shaoyuan continued to say seriously: "But what? We don't know yet, but this is my strength, leave it to me."
"Okay, my friend." Yardley even changed his title: "As long as we can catch this spy, then the Japanese in Chongqing will have no secrets from us!"
