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" codebreakers 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.

fee.

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 all eight telegrams were "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 are 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 was 401, the third set of numbers in the eight messages were all 459. It had rained lightly for a few days in Chongqing, and Yardley speculated based on this that 459 should refer to a rainy day.

401 is sunny.

However, after the Japanese spies were executed, eavesdroppers successively intercepted a batch of secret messages, and the deciphering work was not yet completed.

Subsequently, the Japanese army dispatched fighter jets one after another and caused mass 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 explained 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 man standing guard looked obedient on the outside, but he was disdainful in his heart.

If you really want to do this, given your character, 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 disaster worse than death.

As soon as he entered, he saw his old friend Wei Daming constantly exchanging opinions with a foreigner.

The two looked 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 Mr. Meng Shaoyuan."

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 for any big trouble caused by that time.

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 "China 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 many 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.

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 I can’t do it anymore, yelling and calling myself “damn”?

Yardley, Yardley, you don't understand, Master Meng, I looked at the "Chongqing Air Defense Spy" case very carefully in my own time, and even discussed it with my good friend Xiao Jingyan.

Li 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 contents of the newly intercepted secret messages yesterday and this morning were all a group of 4 numbers, such as 1349, 5727, 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 5 English letters that cannot form words, 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 raised his head, 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.

"Novel!" Meng Shaoyuan said it for him: "This new type of password that changes every day is probably an English novel. If you can find this novel, you can follow the clues to find the spy behind the scenes."
