I was framed for taking the civil service exam, so I joined the National Security Bureau

In addition, Zhang Xing also asked the team leader Geng Jianhui why the forces deployed to investigate the Matsushita Youth Club were withdrawn.

It was indeed consistent with Zhang Xing's guess.

The insider intelligence officer lurking in the Matsushita Youth Club recently reported that the Japanese spy named Kawaki Motoko of the Matsushita Youth Club had already felt that the Matsushita Youth Club was being monitored by the National Security Agency of the Hua Kingdom, so his behavior had begun to be low-key.

More importantly, the insider found out that Kawaki Motoko was originally going to meet an important person on the 20th of this month, but because he noticed that he was being monitored by the National Security Agency, Kawaki Motoko postponed the meeting time.

The leaders of the National Security Bureau suspected that the important person Kawaki Motoko was going to meet was most likely the number one spy in the island country, Junji Watanabe.

In order not to alert the enemy, most of the deployed forces were withdrawn this time, with the purpose of attracting Kawaki Motoko and Junji Watanabe to meet.

This is a very challenging process for both parties.

This deployment operation alarmed Kawaki Motoko. Although it meant that Junji Watanabe would not show up easily, the leaders of the National Security Bureau expected that as long as they wanted to plan a spy case in the country, Junji Watanabe and Kawaki Motoko would meet sooner or later.

It is not difficult to catch a Kawaki Motoko, but if action is taken against Kawaki Motoko at this time, then Junji Watanabe is very likely to escape.

And the main target of the National Security Bureau this time is Junji Watanabe. This time he entered the country, and he will never be allowed to escape again.

At six o'clock in the evening, Zhang Xing went to the third floor of Block F as agreed.

This is where the rat extermination team is located.

Although the rat extermination team belongs to the Intelligence Department, the main purpose of the Violet Cryptographer to establish the rat extermination team this time is to train newcomers in the field of cryptography. For the time being, her rat extermination team will not undertake any tasks of the Intelligence Department.

The third floor of Block F was originally the territory of the Confidential Department. Later, the Confidential Department moved to the third floor of Block D. The third floor of Block F later became a temporary storage place for sundries and communication equipment.

Zhang Xing found the location of the rat extermination team near the corner.

"Report, Zhang Xing, the 23rd intern of the action team, is here to report."

In the rat extermination team office, the violet code officer was explaining the theoretical course to the students of code studies. Zhang Xing came to the door, glanced at it, and hurriedly made a report.

The furnishings in the office were very simple, even a little messy. This office was obviously opened temporarily.

In addition to some necessary office supplies, there were several mobile code radios.

The reason why mobile code radios were used in this office was probably for easy transportation.

There are many types of modern code radios, which can be divided into three types according to their uses and conditions of use:

Mobile code radios, portable code radios and fixed code radios.

Mobile code radios, as the name suggests, are code radios that are easy to move. This type of radio usually consists of a telephone, a mobile terminal and a set of transmission equipment.

Most of them are set up in vehicles, such as the compartment of the intelligence team, which is equipped with such a mobile password radio. During the execution of the mission, the use of the radio can transmit information more safely.

A portable password radio is a small radio that integrates a mobile terminal with a voice message function and a transmission device. Although this password radio is easy to carry, it also has certain limitations. Usually, the signal quality is poor and it is only suitable for shortwave transmission.

Fixed password radios are the most traditional password radios. The users of this type of password radio are usually intelligence departments and military agencies.

For example, in the Intelligence Department of the National Security Bureau, there is a fixed password radio room. This radio room displays many radio equipment, transmission equipment, signal receiving equipment, etc. These devices are connected in series to form a radio room.

Whether it is a mobile password radio or a portable password radio, it must be attached to the radio room. The main radio in the radio room can provide it with signals and shield risks.

Zhang Xing's arrival did not cause too much surprise to the members of the on-site rat extermination team. Everyone looked at Zhang Xing with a very calm and indifferent look.

The violet code officer just glanced at Zhang Xing, then nodded and gestured for Zhang Xing to go to the back row.

Zhang Xing originally thought that he would have to go through a series of procedures such as identity introduction, mutual acquaintances, and conversations with code officers before he could enter the learning state.

But he didn't expect that he would enter the lecture state before meeting the class.

Although Zhang Xing had a little understanding of the basic theory of radio cryptography,The Violet Officer's class today was not about the most basic theories, so Zhang Xing felt a little confused after listening to the whole class.

This rat extermination team is said to be aimed at training new people.

But it seems that they are not very friendly to new people?

After class, the Violet Code Officer specially called Zhang Xing out of the door.

"How is it, how do you feel about today's class?"

In response to the Violet Code Officer's inquiry, Zhang Xing could only tell the truth. For a pure newcomer in the field of cryptography like him, today's class is like listening to a book of heaven.

The Violet Code Officer smiled and said:

"Not bad, at least you don't pretend to know something you don't know."

Zhang Xing was slightly stunned, and he didn't know whether the Violet Code Officer's words were praising or belittling himself.

"According to the original plan, our rodent control team will recruit a group of new cryptographers for training, but now the new trainees have not yet arrived, so the courses I am conducting now are mainly for the old members of the Telecommunications Department. Those theoretical knowledge are indeed a bit beyond the scope for you."

"I suggest that you start with learning the radio, master the basic knowledge of radio use, and try to obtain intelligence through learning the radio. This may be more suitable for members of the action team like you than theoretical knowledge."

This suggestion from the violet cipher officer aroused Zhang Xing's interest. Compared with boring theoretical knowledge, he is indeed more inclined to learn some practical operations.

At about eight o'clock in the evening, the violet cipher officer began to give the second theoretical class to these old members of the Telecommunications Department, and Zhang Xing began to study in front of a radio according to the guidance of the violet cipher officer.

Putting on headphones and operating casually, Zhang Xing turned the FM key and tuned to 90.8, entering a sub-channel.

Soon, a gentle voice sounded in the sub-channel.

"Dear friends, this is the home of radio enthusiasts. Welcome to join us. We will hold online and offline exchanges regularly, and various benefits are waiting for you."
