Fan Keqin continued: "The main reason is that the time cost is too high. He will not do it for no reason."
The analysis team leader also agreed: "Virgo's analysis is right. There is falsehood among truth, and truth among falsehood. This is his code of action. All false things are actually used to cover up real actions in advance. I believe that this Once, we caught him in action. But...he never showed up, and he was in a low-level position, so we felt a little unable to do anything."
Fan Keqin said: "Why does a person disappear? In most cases, it is to avoid risks. The remaining few may want to be quiet, relax, or take a rest. Otherwise, how could a person choose to disappear?"
At this point, Fan Keqin paused and said: "The question is what risk is he avoiding? This matter must be kept secret... But after a thing is completed, does he still need to hide it? I I don’t think so.
You immediately lead your men to check the last time the old Japanese soldier Tufei Yuan disappeared. Pay special attention to when he stopped disappearing. In other words, when did he appear again. Then, what happened in the days before he appeared. I believe that although we cannot decipher all of the telegram records and frequency, the frequency must be recorded, especially the location where the old Japanese soldier Tufeiyuan disappeared and where he reappeared. Records of telegraph signals from these places. Then, based on the approximate sending location of these signals, we can check what happened there. This will virtually eliminate a lot of useless information for us. In this way, if the investigation reaches this step, you will notify me immediately. "
As Fan Keqin explained, the analysis team leader's eyes became brighter. Because it was almost impossible to find out before. But what Fan Keqin said undoubtedly opened his mind, so he immediately stepped forward and said: "Yes. I will do it as soon as I return to my humble position."
"Yes." Fan Keqin said: "I will call the Military Command Intelligence Office and open the past archives and records of the Military Command to you. Your people can put aside other things these days and just check these things. "
"Yes. I understand." The analysis team leader said, "Now go back to your humble position." After saying that, he turned around and walked out of Fan Keqin's office quickly.
Led by Fan Keqin, the overall efficiency of the Security Bureau is now very high. On the morning of the third day, the analysis team leader had already found out what Fan Keqin was talking about. And as Fan Keqin said before, the files and records of the Security Bureau and the Military Command and other information were retrieved as long as they felt they were within the scope.
Are the records really that comprehensive? In fact, it depends on the recording method.
Information wars between China and Japan are happening almost all the time. There are a lot of radio stations, commercial, military, and those specially used for monitoring in the rear, etc., adjusted to different frequencies. It can be said that they are trying to intercept the other party's telegraph signals around the clock.
For example, if a radio station suddenly intercepts a signal, the staff will immediately put on the headphones, take the record book at hand and start recording the information.
Of course, this information may be in an unbreakable encrypted state, such as the Pearl Harbor information. After being intercepted, it was just a string of garbled codes, such as 316A, 0EL59, 71B99, etc. This is encryption. Because with radios, as long as the frequency is right and the signal is within the reception range, you will definitely be able to receive it. So interception is really not difficult. The hard part is how to decipher it.
After the staff record it, they will report it according to the working procedures, and then finally submit it to the deciphering team, which will be compared and analyzed with the content intercepted in the past. They will also look for patterns based on the code book of the little devil seized by their side, etc. This allows deciphering experts to decipher the other party's real telegram content. This is basically the entire process after intercepting enemy information.
But information that cannot be deciphered can never be burned. Instead, it is necessary to mark the time of interception and the approximate range of the enemy's transmission, and then store it in the file.
Now Fan Keqin's analysis team is going through this large amount of previously recorded files.
Moreover, they had already found out the time information about the last time the old devil Doi Enjiro disappeared.
With this, there is a certain basis. Then, as Fan Keqin explained, the analysis team learned when Doi Enjiro appeared again after his last disappearance. This was equivalent to once again accurately delineating the scope of the archives for the analysis team to review.
After the leader of the analysis team and Fan Keqin came to the information analysis office, they said this again, and then said: "Virgin, according to your explanation. We discovered the time when the little devil Dofei Yuan appeared after he last disappeared. It was May 12th. We pushed back the time and checked all the telegraph signals intercepted in the city where Dofei Yuan was located in the previous week. There were nearly thirty messages in total. Excluding several commercials we had that had the same records radio station, as well as the military radio station that had been monitoring. In the end, nine messages were left. We compared the time of these nine messages, and six of them were too long. They were the sixth and seventh messages before Enjiro Doi appeared. Intercepted by genius.
This time is not right. Dohi Enjiro will not wait so long after receiving the telegram before appearing again. Therefore, Beiji and others temporarily exclude them. After detailed inspection of the remaining three messages one by one, it was found that one of them was most consistent with the situation. It happened to be at 8:17 pm on the 11th and was intercepted by the military commander's secret monitoring radio station in the Northeast. Then the next day, the 12th, Doi Enjiro stopped disappearing and returned to the office normally. After that, he started his weird activity trajectory again. "
When Fan Keqin heard this, he nodded with satisfaction and said, "Very good, that's the idea. Have you checked? Where did this telegraph signal come from?"
The analysis team leader said: "In the Myanmar-Vietnam area."
Fan Keqin was a little dumbfounded and said: "Abroad? Is it related to the expeditionary force?"
The analysis team leader said: "Probably not. The expeditionary force fought normally during that period. Although the fighting was very hard, it was still within the normal range. But... I checked what happened in the Myanmar-Vietnam area during that period. That is , Ruan Zhiwen is dead."
Fan Keqin really didn't know much about Ruan Zhiwen, so he asked: "Tell me, what is Ruan Zhiwen's situation?"
"He is the leader of the resistance." The leader of the analysis team said: "The British have been colonizing that area under high pressure before. After Little Japan passed, many local people initially thought..."
