Cooperate with American cipher expert Herbert Yardley to solve the Chongqing spy case?

Brother, don't joke with me, he should cooperate with me to solve the case, okay?

As soon as he came to China, the government selected 30 students to follow Yardley to learn to decipher codes, and the "Chinese Black Room" was established.

The "Chinese Black Room" decipherers work every morning from 8 a.m. to 12 p.m., 2 p.m. to 6 p.m., and 7 p.m. to 10 p.m. A month's salary is 30 yuan in legal currency, and each person has to pay 5 yuan for food.

In addition to learning Morse code, which is uniform all over the world, the decipherers also have to understand a large number of program codes representing the 48 alphabets and kana equivalent to Japanese in Japanese, and the daily learning tasks are boring and heavy.

Of course, the name "Chinese Black Room" won't officially appear until two years later.

The possibility of leakage of intelligence from China's air defense forces was also discovered by Yardley and his trainees.

At that time, the blackroom monitors would intercept some cipher messages at 6 a.m., 12 p.m. and 6 p.m. every day.

Yardley found that these coded telegrams only used 10 letters of the Japanese alphabet, but the Japanese language has 48 letters, what can only 10 letters say?

He guessed that the 10 pseudonyms might have been used to represent numbers, and immediately took out the eight telegrams intercepted in a few days and analyzed them.

The masthead of all eight of the telegrams was "027", which Yardley guessed was likely to mean that the message was sent from Chongqing.

The first three messages were sent at 6 a.m. on different days, and the second set of numbers was "231", so it is speculated that 231 probably refers to 6 a.m.

Based on this, the second set of numbers "248" in messages Nos. 4, 5 and 6 represents 12 noon; The second set of numbers "267" in messages Nos. 7 and 8 represents 6 p.m.

The eight messages were all of the same length, and the third set of numbers all began with 4, which Yardley speculated should provide meteorological information about the Chongqing area, such as weather, cloud height, air pressure, temperature, visibility, wind direction, etc.

The third set of numbers of the eight packets is 459 except for the sixth packet, which is 401. There had been a few days of light rain in Chongqing, and Yardley speculated that 459 should refer to a rainy day, while 401 was a sunny day.

However, after the Japanese spies were executed, the interceptors intercepted a batch of secret messages one after another, and the decipherment work was not yet completed

Subsequently, the Japanese army dispatched fighter planes in succession and successively caused a major bombing tragedy in Chongqing.

The tragedy deeply shook Yardley, and he blamed himself for not catching the spy who provided information to the Japanese aircraft in time. He vowed to catch the black hand hiding behind the scenes.

However, until December, the spy was still at large.

Meng Shaoyuan was tasked with fully assisting Yardley in capturing this deeply hidden spy.

The question is, is Young Master Meng the Lord who is willing to help others?

Who is a spy and who are his accomplices, he is like a mirror in his heart.

I just can't say it.

However, since Dai Li personally explained the matter, he did not dare to slack off, and when he came out of Dai Li's office, Meng Shaoyuan went straight to the "Chinese black room" non-stop.

The guards at the door all knew this Section Chief Meng, and no one dared to stop him, so they invited him in.

However, he Young Master Meng was still very dissatisfied, and he taught the lesson of standing guard, which roughly means that anyone who comes must conduct a strict inventory of Yunyun.

On the surface, he was submissive, but he was dismissive in his heart.

If you really want to do this, with your character as Section Chief Meng, will you not retaliate? If you offend Director Dai, it's a big deal that the family law is enforced, but if you offend Section Chief Meng, it's better to die than to die.

As soon as I entered, I saw that my old friend Wei Daming was constantly exchanging opinions with a foreigner.

The two men looked very nervous, spoke quickly, and even had some heated arguments.

"Old Wei!" Meng Shaoyuan said hello with a big grin.

"Hey, bastard, shut up!"

Unexpectedly, the foreigner roared angrily.

No way!

This is Yardley, right?

How dare you call yourself a bastard?

Meng Shaoyuan's nose was crooked.

As soon as Wei Daming saw that it was Meng Shaoyuan, it was probably to ease the tense atmosphere: "Mr. Yardley, take a break, let me introduce to you, this is Mr. Meng Shaoyuan, the section chief of the Operations Section of the Military Command Bureau." He was sent by our Deputy Director Dai to assist us in solving the case. ”

Unexpectedly, Yardley was dismissive: "What I need is someone who can help with the ciphercode, not a goddamn agent!" ”

I'll rely on it again!

This foreigner is so angry!

Wei Daming's face changed a little, since Nanjing, he and Meng Shaoyuan have been colleagues, he knows this person's character too well.

Yardley didn't know the depths, first yelled at Meng Shaoyuan, and then called him a "damn spy"?

Who offended him, as soon as this Young Master Meng's temper came up, where would he care who you were? When the time comes, no one will be able to bear this responsibility.

Meng Shaoyuan was also really angry, and in normal times, he would have already had a seizure.

If you think about it again, forget it, the establishment of the "Chinese Black Room" is the foundation laid by others, which makes China's cipher code decipherment work quickly in line with the world's advanced level, and there are many detours.

They also made indelible contributions to China's War of Resistance Against Japanese Aggression.

Besides, the investigation of the Japanese espionage case is now at a dead end, and it is inevitable that Yardley will be upset and irritable.

Forget it, forget it.

Count your sister!

Retaliation is avoided, but if you don't show your hands in front of you, you really don't know how many eyes Ma Wang Ye has?

Originally, Meng Shaoyuan knew that although Yardley was in a predicament temporarily, he would soon be able to find a way to decipher the code, and he didn't want to rob others of their credit.

But now it's not going to work, yelling, and scolding yourself for being "damned"?

Yadley, Yadley, don't you know, Young Master Meng, in my own time, watched this "Chongqing air defense espionage" case very carefully, and even discussed it with my good friend Xiao Glasses, and I was full of praise for you Yadli at that time.

I know every detail clearly.

I'm going to have to give you a dismount.

Meng Shaoyuan looked unconcerned, and said in fluent English: "Mr. Herbert Yardley, I have been ordered to come to assist you, and I hope that we can cooperate happily with each other. Old Dai, how is the decipherment going? ”

"It didn't go well." Wei Daming didn't hide anything: "Mr. Yardley, this Mr. Meng is very capable, can I tell him about our discussion?" ”

Yardley snorted in his nose, noncommittal.

Wei Daming picked up a stack of research materials: "For example, the new ciphers we intercepted yesterday and this morning are all in a group of 4 numbers, such as 1349, 5727, and 7234, and the passwords change every day, irregularly. The only peculiarity we found was that the first group of each telegram was 5 unworded English letters, such as mifto, lofed, titth, and so on. ”

"Can you show me?"

Meng Shaoyuan took the information from Wei Daming's hand and looked at it pretending for a while: "It's not difficult." ”

"What?" Wei Daming and Yardley exclaimed at the same time.

Isn't it difficult?

Are you kidding?

Irregular ciphertext, don't you say?

You know, Yardley is America's premier cipher code expert, while Wei Daming is China's telecommunications genius.

The two of them studied for so long and had no clue.

Now suddenly a person comes out and says it's not difficult?

"Look." Meng Shaoyuan took the information seriously: "The first group on this intercepted telegram is the five letters 'ewwee', if my judgment is correct, 'ee' refers to the 11th. This telegram was intercepted yesterday, so yesterday was exactly the 11th. ”

Yardley thought for a while, snatched the information from Meng Shaoyuan's hand, took the pen, and kept writing something.

After almost half an hour, he suddenly raised his head, his face full of ecstasy: "Meng, genius, you are a genius!" That's right, it's like this, it's like this. You see, along this line, the result of rearranging the deciphered letters in monophonic order is, her, light, grain! ”

Wei Daming has been paying attention.

That's right, that's right.

Yardley then said to himself again, "She, the light, the grain? What does this mean? ”

Can't think of it, right?

Don't think about it.

“！” Meng Shaoyuan helped him say it: "This new type of password that changes every day, the secret table is likely to be in English, if you can find this one, you can find the spy behind the scenes." ”

"Yes!"

Yardley reacted immediately. He looked at Meng Shaoyuan in disbelief: "Do you also know the cipher code?" ”

"A little research, a little research." Meng Shaoyuan looked humble.

Yardley's attitude towards Meng Shaoyuan has completely changed.

He loves his peers in this business.

Especially a genius like the young man in front of him!

Wei Daming felt very strange.

He has known Meng Shaoyuan since Nanjing, and he has never heard that he has any deep research on cipher codes?

How could it suddenly be so quickly possible to decipher the top secret code of the Japanese?

Ah, right.

Wei Daming suddenly realized.

Although Meng Shaoyuan did not understand ciphercode, he was definitely a good hand at intelligence work, and his telecommunications office received so many Japanese ciphercodes, all of which he provided.

He must have obtained the cipher code used by the Japanese in Chongqing through some other means, 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, it's fine.

"Mr. Yardley, we can be sure it's a book." Meng Shaoyuan continued to say seriously: "But what? We don't know yet, but that's my forte, so I'll take care of it. ”

"Yes, my friend." Yardley even changed his title: "As long as this spy can be caught, then the Japanese in Chongqing will have no secrets in front of us from now on!" ”
