Traveling through the Republic of China to become a special agent, the system is very easy for me

Yuan Ye was indeed right. Under the leadership of Director Wei Daming, the Shancheng Military Intelligence Bureau's Telecommunications Department's confidential group intercepted a large number of Japanese telegrams every day. The translation group worked day and night to decipher them, but with little success.

Wei Daming was born in Shanghai in 1907. He graduated from the Shanghai Telegraph Training Institute of the Ministry of Communications and later studied in the Class A General Officer Class of the Army University. After graduation, he worked as a radio operator and radio operator in the International Radio Station. In 1938, he served as the Director of the Telecommunications Department of the Kuomintang Military Intelligence Bureau with the rank of Major General.

He invented a miniature radio transmitter with a main unit only the size of a popsicle. Its signal was stronger than that of the American-made military radio transmitters. He successfully deciphered the secret code of the 19th Route Army, allowing the Military Intelligence Bureau to surpass the Central Intelligence Bureau in intelligence warfare, which became a landmark event in which the Military Intelligence Bureau surpassed the Central Intelligence Bureau in telecommunications capabilities.

After Wei Daming was appointed by Dai Yunong as the director of the Military Intelligence Bureau's Telecommunications Department, he set up a telecommunications training class in Shanghai before the Anti-Japanese War to train talents in telecommunications and code for the Military Intelligence Bureau.

In order to prevent the core telecommunications department from being infiltrated by hostile forces, Dai Yunong took great pains. He secretly ordered his fellow villager Mao Qianli, Mao Renlong's younger brother, to return to his hometown, Jiangshan County, Zhejiang Province, in the name of visiting Dai Yunong's mother.

More than 30 young people from Jiangshan County were secretly recruited and trained in the Military Control Commission's radio training class. They were then transferred to the Military Control Commission's confidential department to form the Jiangshan Group, which was mainly composed of this group of Jiangshan people. These people only spoke the Jiangshan dialect throughout their work and were only responsible to Dai Yunong.

Jiang Yuying, the female director of the Confidential Department of the Military Control Commission, is also from Jiangshan. In her early years, she was trained by the Military Control Commission because she was from the same hometown as Dai Yunong and had outstanding abilities. She was Wei Daming's favorite student.

Deciphering secret messages requires technology. Just when the Military Intelligence Bureau was worried about not being able to acquire more advanced technical capabilities, Xiao Bo, the chief of the Military Intelligence Bureau's American station, sent a book called "The Dark Chamber" to Dai Yunong through Wei Daming.

This book is a memoir written by American code-breaking expert Yardley, which describes his participation in the process of deciphering Japan's secret codes.

After seeing this book, Xiao Bo quickly realized the value of this book that almost no one cared about. He immediately asked someone to translate the book into Chinese and sent it to Wei Daming.

After reading it, Dai Yunong was very interested, and Wei Daming also strongly recommended Yadley to Dai Yunong.

After getting Dai Yunong's consent, Wei Daming immediately asked Xiao Bo to contact Yardley to discuss the possibility of Yardley coming to China.

Yardley was born into an ordinary railroad telegraph operator's family in Indiana, USA. He developed a keen interest in telegraphs and telecommunications since he was a child.

During World War I, Yardley joined the US Army. Because of his many contributions in intelligence warfare, Yardley, who was only a captain at the time, was quickly promoted to one of the main leaders of the US Military Intelligence Service (MI8).

His main job was to be in charge of all the US military's wartime code and decryption work, which made a great contribution to the US military's victory in World War I.

After the end of World War I, the huge military structure became a burden for the US military. The director of MI8 suggested converting MI into a bureau-level unit funded by the US State Department and the US military combat command.

This bureau was named the American Dark Room, and was mainly headed by Yardley. In 1919, under the leadership of Yardley, the American Dark Room deciphered some codes of the Japanese Ministry of Foreign Affairs.

Although the American Dark Chamber organizations achieved remarkable results, by 1929, the United States was far away from the war and felt that these formal non-military organizations had no need to exist. At the same time, the United States amended its domestic laws and strengthened the protection of private privacy, so the American Dark Chamber had to close down.

In order to earn some money to support his family, Yardley wrote and published his memoir "Dark Chamber", which did not attract much attention, except from Xiao Bo, the chief of the Military Control Commission's American station.

Thanks to the efforts of the Military Control Commission's American station, Yadley agreed to come to China. Dai Yunong and Wei Daming were very happy about Yadley's arrival.

In September 1938, the Military Intelligence Bureau arranged for agents to assist Yadley in transferring from Hong Kong to Kunming and then to the mountain city.

In order to ensure Yadley's safety, the Military Control Commission arranged for Yadley to live in Shenxian Cave, the official residence of the former mayor of Shancheng.

After Yadley arrived in the mountain city, he saw Japanese military planes bombing the mountain city wantonly almost every day, and he felt the difficulties of the Chinese military and civilians in the war of resistance against Japan.

He felt that the Military Intelligence Bureau's telecommunications department was still very weak, especially in terms of telecommunications decryption talent, and he urgently wanted to train a group of telecommunications decryption talents for China to decipher the Japanese military's secret codes.

Yadley trained nearly two hundred code-breaking talents for the Military Control Commission, including Jiang Yuying, who was the head of the confidential group at the time.

In order to decipher the Japanese military codes, the Military Intelligence Bureau collected nearly 20 million Japanese telegrams, and focused on trying to decipher more than 20,000 of them. The Military Intelligence Bureau's telecommunications department worked day and night, but the code-deciphering work progressed slowly.

This is mainly because this work has just started and the level of decryption needs to be improved. In addition, so far, no Japanese code book has been obtained. If even one Japanese code book can be obtained, it will be of great help to the decryption work.

Therefore, the Military Intelligence Bureau was eager to obtain the Japanese code book. Dai Yunong even offered a large reward to anyone who could obtain the Japanese code book. So far, no one has received the reward.

However, with the help of Yadri, the translation department did make some progress.

The codes of Japanese telegrams are divided into several levels. The lower level is the La code, which is used by consulates to transmit simple information to each other. It is compiled by mixing simple Japanese and English. Each telegram starts with LA, so it is called the La code.

The decoding team did make some progress in deciphering this low-level code, but the value of this intelligence was not great.

The first-level code is the secret telegram book used by the Japanese Ministry of Foreign Affairs, which is an advanced version of the La code. Because it involves Japan's major national policies and military information, it was designed independently by Japan with all its national strength and is said to be impossible to decipher.

If this code could be cracked, it would be of immeasurable value, but the Military Intelligence Bureau's translation department had made no progress in this regard.

This made Dai Yunong very anxious, but there was nothing she could do.

What Yuan Ye didn't know was that the code book of Iwai Yuichi that he wanted to get was one of the more advanced Lacode code books of the Japanese Ministry of Foreign Affairs, but of course it was not the highest-level code book of the Ministry of Foreign Affairs.

However, once this code book is obtained, it will be very helpful in deciphering the highest-level codes of the Japanese Ministry of Foreign Affairs.

At this time, Yuan Ye heard Hirota Naoki leave the office. He should have gone to the communications group to convey Iwai Yuichi's order.

At this time, the phone on Yuichi Iwai's desk rang.
