"What's the situation?"

Early the next morning, Xiao Qi went upstairs to find Chen Miao, although Xiao Qi's emotional intelligence is not very high, but since Chen Miao got married, in the morning, he rarely went upstairs.

Something to say, he will not go up until Chen Miao goes downstairs, or let Liang Xueqin go downstairs.

Xiao Qi took out a stack of photos and put them in front of Chen Miao: "This is the photo taken by the fifth brother following the ambulance yesterday, take a look." ”

"Discovery?" Chen Miao was tidying up his desk, glanced at it, and asked directly.

"Hmm." Stingy nodded, "Third brother, do you look at this thing?" ”

Chen Miao turned sideways, glanced at it, and recognized it: "This is an antenna?" In an instant, he understood, "This is not an ambulance, this is a radio direction finding vehicle disguised as an ambulance!" ”

"I think you're here for us?"

"Not necessarily, there are many secret radio stations in the concession, and if the Japanese want to monitor them one by one, it will be difficult for them to do so with their current technology, otherwise, it will be difficult for our secret radio stations to survive." Chen Miao said, "But if this radio direction finding vehicle appears around us, it is worth being vigilant." ”

Although he cannot be regarded as a professional, he has a certain understanding of the frontiers of communication and cryptography technology in the world today, and has also analyzed and judged the level of the Japanese army's secret telecommunications and radio reconnaissance technology.

There is a radio reconnaissance corps on No. 76, and the technology and personnel are all trained by the Japanese, and the Japanese should not hide their secrets in this regard.

How can they find the underground radio station in Chongqing lurking in the concession?

As a matter of fact, there are many underground radio stations in the concession area, and as Shanghai is the international intelligence capital of the Far East, as long as the Western countries have interests in China, they basically have their own spies in Shanghai, and some even have special intelligence teams.

Therefore, if there are not as many secret radio stations in the concession as a cow, at least there are quite a few, and there are certainly hundreds of active radio stations.

Some of them have existed in the past, and Chen Miao himself has a ledger that records the characteristics of many underground radio stations in Shanghai, as well as the methods and codes of the dispatchers.

The radio direction finding vehicle is dispatched, which is looking for the specific location of the radio station, which at least shows that the other party has mastered the communication law of the radio station, as well as the possible identities of both parties, if it is only to monitor the communication, then there is no need to dispatch the radio direction finding vehicle, only need to monitor the communication.

This shows that the other party's investigation work has reached the arrest stage, or wants to determine the location of the radio station, and then make a district, under normal circumstances, this can already be regarded as the radio station exposed.

But it's not completely exposed, because the other party can't confirm your location and the identity of the sender, and it's still safe before the last step.

"Are we going to continue the radio silence, then?"

"No, once we turn to silence, it will be tantamount to telling the Japanese that we have discovered their existence, and then there is no point in that." Chen Miao said, "This will help them determine our location, we can't be silent, but we can minimize the number of contacts and the time of contact." ”

"Okay."

"Also, let Lao Wu monitor the movement of that ambulance." Chen Miao commanded the above.

"Okay."

The Japanese radio direction finding vehicles drove around his home, Chen Miao didn't think it was an accident or a coincidence, he must have secretly communicated with Queen to listen.

However, the Japanese should not have deciphered their communication codes, otherwise they would have already mastered the secrets of many of their operations.

Such a hidden danger is around us, and it must be solved, and it cannot be kept for the New Year.

Chen Miao thought about it carefully, and a plan gradually took shape in his mind, but there were still some details that needed to be carefully considered.

"Third brother, Xiao Qi, come down for breakfast!"

Hearing Liang Xueqin shouting downstairs, Chen Miao came back to her senses: "Just come." ”

……

"Third brother, I found this thing in our original archives today." As soon as Chen Miao went to work, Lu Wei mysteriously came in with a file that looked a little moldy.

"What?"

"The dossier of the Zodiac Zhou Liu's May Day case the year before last."

"Zhou Liu's five files, isn't that a long time ago?" Chen Miao was surprised, when he first arrived at No. 76, as soon as he took over the archives, Wang Peiwen took advantage of the trouble of looking for this file, but when he checked it, this file had long been gone, and he still clearly remembered that when Wang Fang told him, he had seen this file on Ding Hongzhu's desk, but as Ding Hongzhu was transferred to the communication office, no one mentioned this matter anymore.

Of course, rumors about Zhou Liuwu's private gold collection were still mentioned from time to time, but most people just laughed when they heard it, and no one believed it.

Looking at the file bag that was already a little moldy, as well as the seal that was torn on it, Chen Miao asked in surprise, "Where did you find this?" ”

"In the mezzanine of the waste newspapers, because it was useless, I thought about disposing of the waste newspapers and vacating the space, and this file was discovered." Lu Wei explained.

"The format of this portfolio is a little different from our No. 76......

"It's different, it's the original Zodiac Society's own printed file bag, No. 76 was originally the Zodiac Society's Huxi Office, after Zhou Liuwu's assassination, it was abandoned here, and the things left behind, useful, the Japanese gave them to us when they were handed over to us, and the initial batch of files were packed with this kind of file bag, and later, in order to unify management, we rearranged and compiled the past files, and replaced them with new file bags." Lu Wei said.

"That's right." Chen Miao nodded, "Lu Wei, have you seen the things inside?" ”

"No, third brother, I knew that this file was important, so I didn't dare to look at it, as soon as I found it, I hid it and handed it over to you."

"Well, I see, don't talk about this to the public." Chen Miao commanded,

"Yes." Lu Wei nodded and retreated.

Chen Miao was also curious, what was in this.

Because of the dampness, the file bag was already moldy, so I didn't dare to tear it open, but first put it in the house in the charcoal stove to avoid a little drying, and then carefully took out the contents inside.

Zhou Liuwu is dead, and apart from the whereabouts of a large sum of gold in his possession, almost no one remembers the vice president of the Zodiac Society anymore.

Even Cheng Yuqing, the president, had no living space in Shanghai, and went to Nanjing to fight with Liang Hongzhi.

There wasn't much in it, but some of the paper was damp and moldy, and after drying it a little, it was peeled off one by one.

Zhou Liuwu was assassinated by the military commander, and the person in charge of the investigation was the patrol house of Jing'an Temple in the public concession, and most of these materials were originally in the patrol house of Jing'an Temple.

Later, it was rumored that Zhou Liuwu had a batch of gold hidden at No. 76, and this batch of gold was known only to him, even President Cheng Yuqing did not know.

The Japanese and the Zodiac Society both wanted to get this batch of gold, but Zhou Liuwu was dead, no one knew the whereabouts of this batch of gold, the Japanese and the Zodiac Society investigated for a long time, but they did not find it, and after Lin Shiqun took over 76, the file was also left.

Although the Japanese provided funds, it was still not enough, and Lin Shiqun also had the idea of this batch of gold, but he took the opportunity to renovate No. 76 and almost turned No. 76 upside down, but he still didn't find it.

In the end, a conclusion was drawn that the so-called gold was just fabricated by the Zodiac Society, in fact, this batch of gold had already been squandered by Zhou Liuwu.

This conclusion is still quite credible, the Zodiac Society was very hot in Huxi at that time, and there were groups of thugs under Zhou Liuwu, even Ji Yunqing of the Green Gang was jealous of him, every day he spent all day drinking, living a luxurious life, and this money had already been spent by him.

Since it was just a false rumor, what else was there to do, and in the end, all the investigation files were shelved.

Of course, there are still people who don't give up, thinking that this batch of gold is still there, and they are still looking for it privately, which is another matter.

It was under these circumstances that the dossier was lost.

Chen Miao browsed the file in his hand a little, and found that the things in it were not complete, and some key pages were missing, such as the transcript of the interrogation of Zhou Liuwu's cronies during the investigation, which accounted for a large part, and many of the relevant pages were gone, and they were broken in the middle.

These broken and missing things must be related to the information of "gold", otherwise, for the sake of a dead person, is it necessary to work so hard?

Zhou Liuwu is a person with a wide range of hobbies, visiting casinos, smoking big cigarettes, playing with women, this guy just wants a person with all five poisons, this kind of person is a scumbag of society, it is not a pity to die, not to mention that he is a traitor and does all kinds of evil.

Others can think of people or places where he can hide gold, he has thought of it, and he has also searched for it, and even Zhou Liuwu's accounts in Shanghai's major silver banks have been checked, whether it is in his own name or other people and pseudonyms, although there is some money, but compared with the value of that batch of gold, it is far behind.

After reading so much, what puzzled Chen Miao was where did the huge amount of gold in Zhou Liuwu's hands come from?

Whether the gold was his accumulated wealth or whether it was obtained from someone else is hardly mentioned in the file.

This is very strange, do the people who are looking for this batch of gold know the origin of the gold?

Although he did not plan the assassination of Zhou Liuwu, he was also in Shanghai at the time, and Ling Zhijiang was still the commander of the assassination operation.

Do you want to inquire about the situation like Ling Zhijiang?

Chen Miao thought about it again and again, and felt that it was better to forget it, could it be that he had become like these people, one by one, and he was obsessed with money?

Since it was useless, Chen Miao planned to put away these missing files and put them in the file sheet, but suddenly, Chen Miao found a set of numbers on the inside of the file bag.

This is very strange, the general file number is written directly on the outside of the file sheet in a very conspicuous position, you can see it at a glance.

And this file bag is numbered, not missing, and the number in it is not printed, it should be written later, if you don't pay attention, it's really not easy to find.

Ordinary people don't pay attention to this, and even if they see it, they will feel that this is just a set of meaningless numbers, but Chen Miao is doing intelligence analysis, and he is quite sensitive to any details. sense.

5643。

Four digits, which may be the house number, may also represent a word (Morse 4 numbers represent a Chinese character), 5643 corresponds to a "Xue" character, or it may be the code of a mailbox, or the first four digits or the last four digits of a phone number. (Before the liberation of Shanghai, the phone number was 5 digits)
