About 40 minutes later, Zhou Hexuan was helped into a building, and walked more than ten steps upstairs before he was untied from the black cloth that covered his eyes.

Zhou Hexuan saw that Shen Zui was no longer there, and asked, "What about Xiao Shen?" ”

The military commander spy next to him said: "Director Shen is only responsible for delivering news, and he is not qualified to enter this building." ”

Zhou Hexuan finally began to be surprised, Shen Zui is now the deputy director of the inspection department and chief inspector of the Chongqing Garrison Command, and he is still Dai Li's confidant celebrity, and he is an absolute powerful faction in the military command.

Shen Zui is not qualified to enter this building?

"What is this place?" Zhou Hexuan couldn't help but ask.

The spy said: "This floor is the office of the secret telecommunications team, please forgive me for not being able to tell the rest of the floors, and please don't walk around at will." ”

Zhou Hexuan asked again: "What are you bringing me here for?" ”

The spy said, "I don't know, I'm only responsible for bringing Mr. Zhou over." Please come with me! ”

The two soon came to a room with a sign hanging at the door - the team leader's room.

The agent knocked on the door and said, "Report! Mr. Zhou has been brought. ”

Someone in the house immediately came to open the door, shook hands warmly, and said, "Mr. Zhou, I'm really disturbing today, contemptible Wei Daming." ”

"It turned out to be Director Wei, fortunately!" Zhou Hexuan said.

Wei Daming, director of the Military Command Telecommunications Division, was responsible for intelligence collection during the Anti-Japanese War, and was known as "the soul of Dai Li".

Wei Daming invited Zhou Hexuan into the office, personally made him a cup of tea, and explained the reason: "I invited Mr. Zhou here today in the hope that you can do him a favor." ”

Zhou Hexuan pouted the tea foam and said, "Please speak." ”

Wei Daming said: "Chongqing is a foggy capital, and there is often heavy fog, so it stands to reason that it is difficult for Japanese pilots to bomb accurately. However, every time the Japanese planes bombed Chongqing, it was just in time for a sunny day, and even the night bombing could accurately find the most crowded and prosperous place. ”

Zhou Hexuan said: "Do you suspect that there are Japanese spies in Chongqing? ”

"There must be, but if we can send information accurately in real time, then it is not something that ordinary spies can do," Wei Daming sighed, "In fact, we caught a spy at the beginning of the year, but we were caught by surprise because of this, which caused the Japanese to change the code very complicated." This time, I invited Mr. Zhou to the secret telegram team, hoping that you could help decipher the Japanese army's telegrams. ”

Zhou Hexuan was a little speechless, and said with a wry smile: "Director Wei, I only know simple Morse code, and I really can't help it." ”

Wei Daming shook his head and said, "No, this is Mr. Zhou's strength. We were able to decipher three English words from the intercepted Japanese code, and after repeated research, those three words should have come from an English book. As long as you figure out which English book it is, you can easily crack the Japanese secret code. Mr. Zhou is very familiar with Western writings, and I heard that you have the ability to remember, so I really can't help it, so I thought of asking Mr. Zhou for help. ”

"What three words?" Zhou Hexuan asked.

"Mr. Zhou, please take a look." Wei Daming took out a note.

The words written on the slip of paper were: she, pistol, and never.

It's no wonder that the people in the cipher team can't decipher it, and finding an English book with three words is tantamount to looking for a needle in a haystack.

It's a pity that Zhou Hexuan hasn't read Yardley's "China's Black Room", otherwise he would definitely not have to think about it, and he would be able to directly point out who the Japanese spy was.

Of course, the butterfly effect has caused a small change in history, and the three English words deciphered by the cipher team are completely different from the original words.

Zhou Hexuan shook his head and smiled bitterly: "Give me some more hints." ”

"This English book should be more famous in China or Japan, and it should be easier to find in China," Wei said. ”

"Why do you say that?" Zhou Hexuan asked.

Wei Daming explained: "Our military commander's control of Chongqing is very tight, and most of the spies who sent secret messages to the Japanese invaders have long been lurking, or have never left Chongqing at all. He had to use a relatively common book to communicate with the Japanese military in Wuhan, otherwise it would not be easy to get hold of it in a short time. ”

"Let me think about it." Zhou Hexuan closed his eyes.

Wei Daming didn't bother, but sat quietly next to him and waited.

What English works are well-known in China and relatively readily available in Chongqing and Wuhan?

Zhou Hexuan subconsciously thought of a book, that is, his own "Titanic"! Before the Chinese version of the book was sold in China, many English versions had already been imported from the United States, arguably the most English versions of the book in China - second only to the Bible.

Zhou Hexuan recalled carefully, and sure enough, he found that he had written she, needless to say, and it appeared very frequently; Pistol appears in the dialogue between the heroine's mother and the villain; Never, in a narrative after the shipwreck.

Zhou Hexuan opened his eyes and said, "Try "Titanic". ”

Wei Daming suddenly got up and opened the door, and instructed the secretary: "Go find an English version of "Titanic", immediately!" ”

After about an hour, the secretary finally found the book.

Wei Daming took Zhou Hexuan to the secret code decipherment room and handed the book to a foreigner: "Mr. Yardley, try this book!" ”

"Good!" The foreigner did not operate it himself, but handed the book to a young man.

Wei Daming introduced: "Mr. Zhou, this is Mr. Yardley, a code-breaking expert specially hired by the military commander. Mr. Yardley, this is Mr. Zhou Hexuan, a university scholar in my country. ”

"Hello!"

Zhou Hexuan and Yardley shook hands with each other.

Yardley, the father of American ciphers and former head of the U.S. Military Intelligence Decipherment Section (the predecessor of the U.S. National Security Agency), was hired by Dai for a monthly salary of $10,000.

Zhou Hexuan didn't know much about Yardley, because he was deliberately ignored by both China and the United States after the war, and his book "China's Black Market" was banned by the United States for more than 40 years. Zhou Hexuan did not have access to this book, and it was impossible for him to deliberately use the Internet to search for relevant information.

To be honest, even if Zhou Hexuan knew this, he couldn't rely on memory to help decipher the code, because history has changed - the original Japanese spy used Pearl Sai's "Earth", but now it has been changed to use Zhou Hexuan's "Titanic" as the code book.

Catching a spy is not the key, the key is to decipher the code and then send the wrong message to the Japanese through the code.

The Soviet pilot Kurishenko was able to successfully bomb the Wuhan airfield because Yardley, after breaking the code, sent the Japanese army in Wuhan a message that there was heavy fog in Chongqing. This made the Japanese planes in Wuhan not dispatch that night, and most of them were parked at the airport, and they were given a pot by the bombing squadron led by Kurishenko.

Historically, Yardley has been as bizarre as making a movie to decipher the code.

First of all, the secret telegram team did not succeed in finding the English book that served as a code book, but Dai Li's military commander's agents discovered the Japanese spy. After confirming who the spy was, the military commander did not dare to arrest anyone for fear of startling the snake, and he had to confirm the English book before daring to attack.

The most amazing thing is that the spy is actually a friend that Yardley met at the bar.

What's even more amazing is that Yardley gets help from another friend he met at the bar. This friend is still a woman, named Xu Zhen. According to Yardley's account, Xu Zhen should have been Wang Zhaoming's underground lover before he surrendered to the enemy......

Yardley was very bold, and he told all his identities and the predicament he was facing when he knew that Xu Zhen and the traitor Wang Zhaoming had a close relationship. Then, Yardley took Xu Zhen to the spy's house as a guest, and the spy heard the air raid siren and left. Yardley chatted to stabilize the spy's girlfriend and asked Xu Zhen to go to the spy's study, and finally found the English book.

This strange woman named Xu Zhen, although she was Wang Zhaoming's lover, she made great contributions to the Anti-Japanese War, and was finally assassinated by Japanese spies.

After dozens of codebreakers were busy, in less than an hour, someone came to report happily: "Director Wei, Mr. Yardley, we have compared and tested more than ten Japanese telegrams that have been intercepted recently, and the codebook they use is the Titanic!" ”

"Well done!"

Yardley hugged Zhou Hexuan and patted him on the shoulder: "Zhou, you have done me a great favor." ”

"You have done the Chinese people a great favor." Zhou Hexuan said with a smile.

Dozens of decipherers under Yardley were all students who had returned from Japan, because most of the Japanese army's telegraph codes used the Japanese alphabet. Who says it's useless to stay in Japan? At least these telegraph coders intercepted countless Japanese military intelligence in the War of Resistance Against Japan.
