After Zhuang Xiaoman rode out, Fan Keqin immediately came to a bicycle and unlocked it. He got on the bicycle with one leg, kicked hard a few times and followed.

Back-and-forth security measures are very useful when the agents are going where they want to go. I still remember that when they were tracking Guan Manyuan and his wife, who turned into noodle shop owners, this pair of Japanese special elements used this method.

The intelligence agency agent who was following at the time was almost discovered by the other party's method. If Fan Keqin hadn't reacted astutely and alerted his men with a bullet, the tracking might have failed.

The difference between good and bad methods is not that big, but it is different for each person. If this method is in the hands of mediocre people, it may fail. But now that Fan Keqin comes to use it personally, the effect is not comparable to that of ordinary people.

.Let alone ordinary people, there are very few excellent agents who cannot compare to Fan Keqin.

We always say that the body is the real capital, and now Fan Keqin has proved this. His physical qualities in all aspects are very strong. For example, his eyesight, regardless of distance, can see much more clearly than others. The brain reacts

Speed, memory ability, analysis speed, etc., etc., after all these things are combined, it can lead to the fact that Fan Keqin does not need to follow too close. Just keep a distance that is close to the limit of visual distance.

In this way, even if someone is really targeting Zhuang Xiaoman, they will never dare to follow him further than Fan Keqin. Therefore, being discovered by Fan Keqin is almost inevitable.

Having said that, the best result is naturally not to be noticed by others. This was the case at this time, all the way out of the south of the city. When we arrived in the suburbs, the road conditions here were worse than in the city.

Fortunately, the direction of the port is southeast of the city. Therefore, a section of the road in the southern suburbs of the city is still ok.

But after about ten minutes, Zhuang Xiaoman stopped taking the right path, and instead turned a corner and entered the side road. After riding for another ten minutes, Zhuang Xiaoman looked around and saw a dirt bag behind him.

Stopped.

Zhuang Xiaoman pushed the car and turned behind the earth bag. He saw a dead tree here, which had fallen to the ground. Because the roots may have been rooted at the foot of the earth bag, a tree naturally formed in the earth bag.

sunken place.

Seeing this, Zhuang Xiaoman put down the car, walked to the small depression, and looked up, down, left, and right in detail for a while.

Finally, she picked up a stone and smashed it slightly hard on the upper edge of the sunken area. Then she stood up and looked around again. After looking around, Zhuang Xiaoman finally looked around again.

He picked up the car and started walking back.

When Fan Keqin saw this, he didn't shy away and just stood there and waited, because he had already observed it before and there was no one around. So there was no need for him to pretend that he didn't know him.

After the two people met, Zhuang Xiaoman said: "I have chosen, I will contact the field team now."

"Okay, you go first." Fan Keqin replied, then took out a cigarette, lit it for himself, and took a puff.

Zhuang Xiaoman kept moving. After pushing the car and missing Fan Keqin, he kicked the ground hard, got in the car, and rode forward. Fan Keqin stayed where he was, taking a few puffs of cigarette and looking around.

There is still no one there. This is normal. After all, after observing along the way, this is a blank area with no human habitation at all.

It wasn't until Zhuang Xiaoman rode far away that Fan Keqin threw away his cigarette butt, jumped on the bike, and followed.

In this way, the two people returned to the city again and followed Zhuang Xiaoman all the way to the telegraph office. Fan Keqin came to a tea stall and parked the car quite far away. He followed the direction facing the gate of the telegraph office and said: "Boss.

, bring a pot of tea. Herbal tea is best."

The boss said "Okay." He immediately served a pot of herbal tea. Fan Keqin asked about the price and paid the money directly.

After Zhuang Xiaoman entered, he started to send the report. So he sent the report so openly? He really did it openly.

Because the people who come to the telegraph office to send messages are all like this. As for the transmitter, the principle of this thing is actually just radio.

As long as it is within the band and within the distance, it will definitely be received. Even the military radio is the same. This is also on the battlefield, often both sides can receive the enemy station's information, but whoever can decipher it faster will win.

Able to take the initiative.

After all, the content transmitted by military radio waves is encrypted. If you use the most common means to decipher it, it will be a lot of garbled codes that are incomprehensible at all. Only by mastering the rules of passwords can you figure out the specific content.

.So if you collect it, as long as the frequency is right, anyone can collect it, but not everyone can read the content. The same goes for the opposite.

Now Zhuang Xiaoman is using this method to use clear codes, but what he sends are code words.

What does it mean? A very simple truth, that is, you have made an appointment with someone, even if it is "I will fuck your uncle". As long as you see this sentence, when and where you are

, went to meet me. But the content was just "I fucked your uncle". No one could tell that it was for a connector.

And you can make many kinds of appointments, such as: I have received the aunt, she is fine, please don't worry. But the actual content is the same as the agreement: when the enemy is found, everyone will lurk.

Zhuang Xiaoman sent a telegram that was in the nature of a family letter. It was of moderate length: Feifei is doing well in her studies and will graduate this year. She will invite her sister home then. The signature is: Feifei.

The reason for this is because the code is clear, but to prevent anyone from actually reporting that their studies are really overlapping, that would be fucked up.

Therefore, the academic report talks about Feifei's studies, and it must be in line with graduation this year. In addition, she invites her sister to come home. The signature is the word "emerald", which means it is the only one.

After sending it, Zhuang Xiaoman gave the money and walked out of the telegraph office.

So don’t they have their own radio station? Why don’t they use it? Because the secret service radio station should be used as much as possible. Even if you carry it, you must try to use other methods to contact it. You can’t just say that you have a radio station and you can use it.

After Zhuang Xiaoman came out, he stopped riding his bicycle and pushed the bicycle into a small alley. When he came out again, the bicycle had disappeared. Although the chance is low, you are not afraid of ten thousand, just in case, if you really bump into it

If you lose your car, it will be a little troublesome.
