Why did the Lucky Tree Liu Tian have such a clear and profound memory of this flower pot? This must have had an important memory value to him.

What's the point? There were potted flowers everywhere on the windows and windows of the houses along the street. Why was it that he only had a deep impression of these flowers? They must have a unique meaning for him.

Ning Zhiheng had read about similar scenes in the novels of espionage in his previous life. A pot of fresh flowers was very common, but at a specific location, a pot of fresh flowers placed at a specific time would have a completely different meaning.

Ning Zhiheng had no way to explain how he had obtained this clue. It was all thanks to the magical power of the Bodhi tree that he was able to obtain this clue.

More importantly, he didn't want anyone to know about the existence of the Bodhi tree. This was the greatest secret he had in his previous life. It was also where he had been able to survive. It was his life treasure. He would never tell anyone, not even the least bit of it to those closest to him.

Thinking of this, Ning Zhiheng had a headache, but he had to try his best to find a way to warn Huang Tao Guang. He decided that he would first make contact with this Huang Liguang and then act according to the circumstances. In order to be able to uncover the hidden Japanese spies, he had to go all out.

Ning Zhiheng rushed over to the intelligence department and asked about Huang Tao Guang's office. At this time, Huang Tao Guang was in his office, looking at the pile of materials in his hands and feeling a headache.

As the main agent in this Japanese spy case. After spending so much effort, they still ended up empty-handed, only getting three ice-cold corpses.

With his experience, he clearly knew that this was only a very small part of the Japanese team. The hidden tissue behind it was completely undamaged.

No matter how this report was written, it would be difficult for his superior to be satisfied with such an outcome.

At this moment, there was a knock on the door. He opened it to see that it was Ning Zhiheng standing at the door, which surprised him.

This young fellow in the squad. He had only met Fu Cheng twice. The first time had been during the previous operation of arresting Fu Cheng, and the second time had been not too long ago, when he had met him in the torture department's basement.

However, as an intelligence officer, his memory was very good. He remembered that this young officer had shared his information during their first meeting. This young officer's name was Ning Zhiheng, and he vaguely heard that this person had some background.

"I wonder what business does Brother Ning have with this sudden visit?" Huang Tao Guang invited Ning Zhiheng into the office.

Ning Zhiheng looked around and quickly caught sight of the stack of documents on his desk. It was probably the file on the case of Lucky Tree Liu Tian.

He smiled and said, "I have some things I would like to ask you. I hope Brother Huang will be generous with your advice. "

"Oh, your brother here has something to ask you. "Please be direct, I will tell anything I know." Huang Tao Guang replied enthusiastically as he turned around and poured Lin Zhiheng a cup of tea. They brought it to him and sat down facing each other.

Ning Zhiheng thought for a moment and softly asked, "Brother Huang, I would like to ask. With your experience, what sort of role should this Fu Cheng play in a spy organization? What was his role? "

Huang Tao Guang nodded with a smile. He knew that Ning Zhiheng was a graduate of Huang Po who had just been transferred to the Action Team.

It could be said that in terms of training and training of intelligence agents, the government of the Republic of China at this time was still not mature enough.

A lot of espionage and knowledge, except for professionals like them, is hard to come by.

Since Ning Zhiheng had joined the Military Intelligence team, it was only right and reasonable for him to want to know more about this.

Huang Tao Guang admired young people like Ning Zhiheng. This kind of young man was good at learning and loved studying. He was very willing to learn new knowledge.

There is a great lack of intellectual talent in the country these days. He was willing to spread basic secret knowledge to Ning Zhiheng.

He smiled as he replied, "We found a radio station at this Fu Cheng's residence. This shows that he is a character who specializes in transmitting information." We have a common term for such people, "carrier pigeons."

As a key part of the intelligence spy organization, the carrier pigeon is also a transit point for intelligence transmission between the spy team and the spy headquarters.

All the information would eventually fall into his hands and be relayed to the spy's headquarters, as well as to the radio station, where he would receive orders from his superiors. Beside Fu Cheng, there were still two Japanese spies who had specifically hidden themselves to provide support and cover for him. One could imagine the importance of his identity.

We usually call the spies who lurk within our government "moles." Such spies are valuable, too. They are usually the ones the enemy paid a great deal of money to infiltrate, and their identities are even more reliable and covert than the real ones.

A spy team can have one or more moles, but a carrier pigeon can only have one. It was precisely because of its importance that Fu Cheng's fall this time around would definitely alarm the other members of this group.

This reaction time would be very short, and then they would quickly enter a concealed state. Only when they were certain that it was safe would they obtain the activation command through other predetermined methods, only then would they begin their new operation.

For us to solve this case with this kind of method, the difficulty will increase exponentially, and our chances of success will be extremely slim. "

Ning Zhiheng finally understood the importance of Liu Tian's Lucky Tree in the organization. He asked, "What kind of methods do moles usually use to send messages to carrier pigeons?"

Huang Tao Guang then patiently explained, "According to what we know about the transmission of information, there are generally a few types.

The first way is through direct contact. The two of them contacted each other and directly transmitted the information to each other. The benefits of this approach are immediate and effective, but they are also more dangerous. To use such a method meant that the two of them definitely knew each other, and even knew each other's identities. Once they failed to grasp one of the links, they would be able to find other members of the organization. This was also the most basic method.

The second way is to send the message in writing, and the mole sends the message directly to the carrier pigeon. According to the pre-set code and text order, inlay the information content into a normal letter content and send it directly through the post office. This method was relatively safe, but it had a great drawback. The mail delivery time would be very long, because the current postal system was not strict, and the delay or even loss of mail was very serious. If such a thing were to happen, it would be impossible to control it. Thus, they would normally not use such a method to transmit information.

The third way is by indirect delivery, usually by setting up a specific hiding place, which we usually call a "dead mailbox." Mole placed the information on the dead mailbox. The so called dead mailbox must be a very secret location. In order to minimize the possibility of the dead mailbox being exposed, the carrier pigeon couldn't go and check for information frequently. This requires the mole to remind the carrier pigeon of this information by other means. This was a method in which neither of them came into contact with each other, and neither of them knew the other party's age, appearance, or identity. The advantage was that the transmission of information was extremely safe. The disadvantage of this method was that it was very complicated, which was very suitable for information that didn't have much effect. Not suitable for urgent information.

They even used the method of publication to transmit information. It was also to put the content of the intelligence report into the article according to the agreed code and order.

It's been used a lot in the last few years, and it's said that the Red Party's underground parties often use it to spread information. But it was seldom used now.

"Because this method is rather risky, everyone is focusing more on this aspect. Our Military Intelligence Department has a special team that will examine the newspapers on the market professionally. Any suspicious information that they find will be screened."

Ning Zhiheng only realized how profound the knowledge in intelligence work was after listening to it. There were many ways and means involved, and it was impossible to not participate.

"Is it possible that the Mole himself has a backup radio station?" "After getting the information, send it directly to the headquarters." Ning Zhiheng thought of a more direct method and continued to question him unwillingly.

"It is also possible, as far as we know, that this is very rare.

This was because this method had many drawbacks. As a mole who has access to our confidential information, his identity is definitely an important member who has access to it. These people are extremely important to the spy organization.

The cost of nurturing such a spy was extremely high. Any of these informants were extremely valuable to the organization. They would not place such valuable agents at unnecessary risk.

This was because the secret service had a telecommunications department that specialized in listening in on all kinds of radio stations. Just like our MIS has a more advanced telecommunications department.

If they heard strange radio signals, they would check them out. Determine the frequency and range of the issue. Once a search was carried out, the radio station could easily be exposed. It could be said that sending the telegram itself was more dangerous and the risk was still higher.

The Japanese spies were always very strict in their methods of doing things. They usually divided up the work, the mole obtaining information, and the carrier pigeon passing information. This way, they could share the risk between the two and minimize the risk of exposure.

The Red Underground Party, which the Central Party Investigation Department had seized last year, had been suspected of identity precisely because the hidden mole had reported it directly, but the mole had resolutely swallowed his own gun and ended up with nothing.

There are also many other ways to transmit information, but there are no fixed methods. Everything depends on the actual situation. " Huang Tao Guang continued to explain.
