After careful observation, Lin Mo discovered that the radio station installed in this radio should be a small radio station specially developed for spies.
However, because this radio is not small, Lin Mo does not know how small it is, and the inside of this radio has obviously been modified.
Thinking of this, Lin Mo turned on the radio, and music sounded immediately.
Lin Mo was shocked when he heard the music. Of course, Lin Mo was not shocked by the music. He had no musical talent and no interest in music.
What shocked Lin Mo was the size of this radio station, because the radio station at this time was clearly working normally, which meant that the radio had also been modified by the Japanese.
But in any case, if you want to gather all the radio and radio components together, but still have to leave a lot of space to place the radio components, then the volume of the radio will definitely not be large.
Seeing Lin Mo's surprised expression, Liu Zhenshan asked with some confusion: "Lin Mo, what's wrong with you? Why do you have such an expression?"
Hearing this, Lin Mo said: "Brother Liu, look at whether this Japanese spy's radio station is too small."
Then, Lin Mo explained his inference to Liu Zhenshan in detail.
After listening to this, Liu Zhenshan also looked at the radio station carefully and said: "This thing is really well made, but there is nothing surprising. The power of this thing should not be very high."
"There are some differences between our intelligence organization and the radio stations used by your army. This radio station should only be able to contact Shanghai."
"Moreover, this thing is very expensive to make and is not suitable for large-scale use by the army. Moreover, the distance will be greatly affected. Your army is not equipped with it at all. It is normal that you don't know."
Of course Lin Mo knows these things, but the distance between Nanjing and Shanghai is not close. It is very good that Japan can make such things.
Because the size can be reduced to such a small size, the technology used, in Lin Mo's opinion, can already make the kind of walkie-talkies that the United States equipped in the late Pacific War.
But after hearing what Liu Zhenshan said about the price issue, Lin Mo also reacted. The technology for this thing should have just come out, so the price will definitely not be low.
Just like the telephones of later generations had just come out, the price was simply incredible. In this era, except for the wealthy Americans in the late war, given the situation in other countries, they might not even have this idea.
And even the current Americans, with the world's largest economic strength, may not dare to really popularize this new technology in the face of this new technology.
This technology, at this time, can only be used by lurking spies.
Seeing that Lin Mo was thinking about something, Liu Zhenshan thought that Lin Mo was still surprised by this radio station, so he quietly put his head next to Lin Mo's ear and whispered: "Actually, we also have this thing."
Hearing this, Lin Mo turned to look at Liu Zhenshan, with a little surprise on his face.
Seeing this situation, Liu Zhenshan smiled and whispered: "Our Military Intelligence Department has also produced this thing, but due to technical reasons, many parts have to be purchased from abroad."
"Not only is it difficult to buy, but the price is also very high, so not many can be produced."
At this point, Liu Zhenshan stopped decisively and stopped disclosing other information to Lin Mo.
However, these words allowed Lin Mo to immediately analyze countless things about the Military Intelligence Department based on what later generations would know.
When Lin Mo was in later generations, he already knew that the Military Intelligence Department did a very good job in deciphering and was famous all over the world.
Judging from what Liu Zhenshan just revealed, the military intelligence office's deciphering work has obviously begun and has made considerable progress.
In this way, once Lin Mo and the others find the Japanese spy's code book this time, their contribution will become even greater.
Thinking of this, Lin Mo began to look around and search to see if he could find the Japanese spy's code book.
Seeing Lin Mo continue to search, Liu Zhenshan asked: "Lin Mo, what are you looking for?"
Hearing this, Lin Mo stopped what he was doing, turned to Liu Zhenshan and asked: "Brother Liu, can you tell me whether the Japanese spy's code book is a specially compiled code book, or is it just a code book?
An ordinary book can be used as a code book?"
Hearing this, Liu Zhenshan smiled bitterly and said, "Lin Mo, until now, we have never even seen what a Japanese spy's codebook looks like."
Hearing this, Lin Mo was stunned at first, then shook his head in disappointment, and planned to continue searching.
Seeing this situation, Liu Zhenshan smiled and said: "Lin Mo, don't worry! Just because others don't know, it doesn't mean that I don't know."
Hearing this, Lin Mo also knew that he had been teased by Liu Zhenshan, but Lin Mo was not angry, but quickly said: "Brother Liu, please stop joking with me and tell me quickly."
Hearing this, Liu Zhenshan put away the smile on his face and explained: "Although we have not recovered the code books of Japanese spies, I have seen many destroyed ones."
"Every time I go into action, I will dig through the ashes of the Japanese spies. Although many of them have been burned, there are still some traces left."
"According to my observations, both types of codebooks should exist. From the perspective of my spy organization, this specialized codebook should only be a codebook with a high level of confidentiality."
"The code book of a book should be a higher level of confidentiality, or even a code book dedicated to one-on-one contact. However, this situation should be very rare, and we have only discovered it once."
"When this happens, I guess it was done to keep it secret. After all, books are used as code books for communication. If you hide it, then we will definitely know that it is a code book when we find it."
"And outside, once we capture two groups of spies using the same book, we can also deduce which book is the codebook."
"And if each Japanese spy group uses different books, how many types of books do you think the Japanese spy group should prepare? It would take a lot of energy."
"And another disadvantage of books is that they are very troublesome to destroy. After all, most books are not small, and it takes more time to destroy them. And once they are not completely destroyed, we can still use these things to buy books for comparison."
"But the specially compiled code book is different. This thing is not much bigger. It is a small book. It is not only easy to destroy but also easy to hide. And once it is destroyed, even if some corners are left, we will not gain anything.
useful information."
"I guess that the Japanese spies who can use the books should only use the Japanese spy team with a very high level of confidentiality, and the books used are not easy to find."
"Because when we found the book, we also found some bits and pieces, but until now we haven't been able to compare which one it is. Moreover, this group of Japanese spies, in order to cover up the book, they have a lot of various markets there.
A rare book."
"And until now, we still don't dare to tell whether the code book he burned was a real code book or just to confuse us, and his code book is still in the pile of books."
After listening to Liu Zhenshan's analysis, Lin Mo was a little surprised. Of course, the surprise was not the things he analyzed. After all, if Lin Mo knew this information, it would not be difficult to analyze it.
What surprised Lin Mo was Liu Zhenshan. You must know that the image Liu Zhenshan displayed these days was a bold and rough image. He was completely different from Liu Zhenshan, who was analyzing things clearly and logically at this time.
Sure enough, future generations will not deceive me. People who can get involved in intelligence organizations and still stand out are not simple people.
Just like Liu Zhenshan in front of him, underneath that rough and bold appearance, there is also a delicate heart hidden.
However, these things did not exceed Lin Mo's expectations. From the beginning, Lin Mo never regarded the people in the Military Intelligence Department as stupid people. Instead, he always controlled the situation and dealt with them carefully.
Now it seems that the situation Liu Zhenshan just explained to him should be revealed by the other party after he judged that the Military Intelligence Office was interested in recruiting him.
However, Lin Mo didn't want to think too much about these situations. After all, it was in his own interest to finish this operation perfectly. As for other things, let's wait until the operation is over before thinking about it!
Thinking of this, Lin Mo carefully thought about the information Liu Zhenshan just provided, and looked around again. He found that there was no way to find the code book, so he stopped what he was doing.
Because there is so much information displayed here, but there are not many books, it is obviously not consistent with what Liu Zhenshan said about using books as codebooks.
Seeing Lin Mo stop and searching, Liu Zhenshan asked with some confusion: "Lin Mo, why did you stop?"
Hearing this, Lin Mo smiled bitterly and pointed around: "Brother Liu, look at this situation, can we find the code book?"
After hearing this, Liu Zhenshan took a look at where Lin Mo pointed and saw that there were piles of information everywhere.
Seeing this situation, Liu Zhenshan smiled bitterly, stopped what he was doing, and asked, "Then what should we do now?"
Hearing this question, Lin Mo thought for a moment and said, "Let's not search now. When the truck comes, take these things away and let those of you who are responsible for searching these things have a headache!"
"Uh... I'm the one who usually does the searching."
Hearing this, Lin Mo was stunned at first, feeling a little embarrassed that he had done this. However, when he thought that the matter of finding the code book had already been given to the Military Intelligence Office, a look of gloating suddenly appeared on his face.
Looking at Lin Mo who was gloating over his misfortune, and looking at the piles of information, Liu Zhenshan also felt a headache.
Liu Zhenshan looked at the information a few more times, waved his hand helplessly, and said: "This search is not my business alone. I'd better solve it together with other people when the time comes."
