He said: "Can you get in from the second floor? After entering, open the window downstairs and my people can get in!"
Ge Er chuckled and said, "It's a little trick, don't worry about it."
As he spoke, he climbed over the fence silently and entered the backyard. He walked a few steps along the building and quickly climbed up.
Chen Zifeng looked on the wall, extremely surprised.
Ge Er was like a gecko, climbing to the second floor easily. He reached out and hooked the window, and the window opened. After that, Ge Er was like a snake, bending and twisting, and quickly slid into the window!
It was as if someone was pulling him in!
Chen Zifeng was stunned and didn't know how he did it.
Only a few minutes later, a window on the first floor opened. A dark figure waved outside.
Chen Zifeng's brothers had no problem climbing over the wall. They helped each other, delivered several heavy bags in, brought in the small ladder, and quickly climbed into the window on the first floor.
Yang Sanqiang entered the building and said in Ge Er's ear: "Second brother, you and Captain Chen are on guard outside! Go quickly!"
Ge Er originally wanted to see what these people were doing when they came in with big bags. But when he saw Yang Sanqiang's stern eyes, he had to quietly come out and climb over the wall to Chen Zifeng.
Chen Zifeng pulled him, found a dark corner and squatted down, and said with a smile: "Second brother, you went in, didn't you touch other people's things? Or left any traces?"
Ge Er's eyes widened, "Leave traces! I, Ge Er, am so stupid! I will sue you without even a trace! Don't worry!"

At this time, Xiao Ancheng's team had already begun to install bugs.
The Overseas Chinese Affairs Committee of the National Government is located on Zhongshan 1st Road, very close to the Wenmo Lane station. They arrived at about ten o'clock.
The Overseas Chinese Affairs Committee was a cold yamen. By this time, the building had long been deserted and it was as quiet as a cemetery.
It was Gouzi Ting who also opened the way. Qiao Yanfang, Qiang Hu, Li Xuehai and others quickly got in, found Chen Chunpu's office, and started the installation work.
Xiao Ancheng, Gou Zi, and two brothers were observing nearby to see if there were any unusual characters. If so, they would create some trouble to send a signal to the people inside.
Qiao Yanfang, Qiang Hu and others entered Chen Chunpu's office, first drew the curtains, then turned on the lights, then stood in the middle of the office and looked around.
Li Xuehai looked at them with his mouth open, guessing that they were observing the location where the bugs were installed.
Qiang Hu said: "Xiao Qiao, just put it on the phone. The table is against the wall, so it's easy to route the wires."
Qiao Yanfang nodded and said, "Okay, let's get started."
Each of these people performed their duties, taking out various things from the big bag, and soon spread them out in a large area on the ground.
Li Xuehai's task at this time is to deliver various small things to them.
Qiang Hu is a rough man, but what he is doing at this time is the most delicate job, installing bugs.
He spread out a newspaper in the middle of his desk, put the phone on the newspaper, opened the tool bag, and began to disassemble the phone. He removed the microphone and telephone wires.
He opened a small box and took out a bug the size of a button.
This eavesdropping device is actually just a small component of the entire eavesdropping device. Its name should be a microphone. Its common name is a microphone, which is transliterated from the English microphone (microphone).
The eavesdropper currently installed by Qianghu is a carbon microphone. Its working principle is that the sound vibrates the diaphragm, and the diaphragm compresses the carbon particles, which changes the conductivity of the carbon particles, thereby converting the sound into an electrical signal, and then transmits it through the wire.
.
But the phone in front of Qiang Hu is very wicked!
When it is placed on the table, its internal voltage is 48v DC. When you pick up the microphone, its voltage is 12v or 18v. When you start talking, it is in addition to 48v DC, plus
Connect 25v alternating current. This alternating current is for transmitting audio! Do you think it is immoral or not?
If the eavesdropper wants to use the electricity in the phone, it can only use 48v DC! This electricity is always available!
Therefore, Qianghu must find this 48v wire, and it is best to measure it with an electric meter to make sure it is correct!
Now that the eavesdropper has electricity, it can work. But the electrical signal it obtains must be transmitted to the recorder through a special line. What Qianghu is doing now is to prepare to lay out this special line!
The wires on the microphone are two copper wires wrapped with rubber. They are twisted together and wrapped with a layer of braided cloth. In this way, the wires look good and are safe.
Now, Qiang Hu took a very thin steel wire and threaded it through the braided cloth outside the wire. After the steel wire emerged at that end, he hooked the special wire they brought and pulled it out.
This special wire is very thin, and it is indeed dedicated to bugs.
This job is very troublesome and requires a lot of patience and care.

This guy Qiang Hu is just a rough guy, and he is very annoying.
He complained: "Tell me, Xiao Qiao, why can't this thing be made wireless? Radios are wireless and can be received at dozens or hundreds of kilometers! Radio stations can be received at hundreds or thousands of kilometers.
Received! This thing is only a few hundred meters away from the listening point, why can't it be transmitted wirelessly?"
At this time, Qiao Yanfang was squatting under the table, busy with her work, installing the repeater.
She said angrily: "How big is the radio? How big is the radio! For a bug to be able to emit wireless signals, it must be connected to such a large device! Tell me, where did you hide such a large device!"
Qiang Hu could only say: "That's right. It would be nice if this device could be made smaller."
Qiao Yanfang said: "The electronic tube in the radio station is as big as a light bulb. How can this device be made smaller? Unless the electronic tube is only as small as a fingernail! Do you think it can be made that small!"
Now, Qiang Hu had nothing to say.
Therefore, eavesdroppers can only transmit signals through wires. He thought that maybe people in the future would be smart enough to make electronic tubes as small as a fingernail!
The equipment Qiao Yanfang is installing now is a small iron box as big as a palm, called a repeater. It is also an indispensable small piece of equipment for installing eavesdroppers.
The bug can be installed in a phone, which naturally uses direct current. But it can also be installed in a desk lamp, which uses alternating current. Therefore, this small box must have a rectifier.
There is a switch in the small box that determines whether AC power needs to be converted into DC power.
In addition, as mentioned before, the phone is very bad, and its voltage is not very accurate, so the voltage needs to be adjusted to a suitable voltage through a transformer. Finally, the electrical signal generated in the microphone is very weak, and the signal needs to be gain, and then
Passed to the listening device through wires.
But this box is as big as a palm, so it is difficult to hide. Qiao Yanfang can only install it under the table and behind the drawer.
If someone gets under the table and looks up, he can see it. If he pulls down the drawer and looks inside, he can also see it. Once it is seen, the bug will be exposed and will definitely be dismantled!
But the life of a bug is always short-term! If it can remain effective for a few months, it is considered very good!
There is nothing we can do about this! The set of bugs they installed is the latest product and is already very advanced!
Qiao Yanfang installed the repeater, and then connected the wires hidden by Qiang Hu. The first step of installing the bug was completed!

In the Ministry of Foreign Affairs, in Zhou Longxiang's office, it was Yang Sanqiang who was responsible for installing bugs and repeaters.
Li San is responsible for laying wires on the wall.
He started from the wall next to his desk, used a wooden ruler to compare, and then used a special tool with a three-pointed tip to draw a line on the wall. He worked hard and drew a line about two millimeters deep on the wall.
of shallow grooves.
Next, he began routing wires in this shallow trench.
He said to Han Jindong: "Stapler!"
Han Jindong hurriedly found the stapler, installed staples in it, and handed it to Li San.
He was surprised to see that Li San was using a stapler to staple very thin wires into the shallow grooves. He nailed them at an angle, and both the staples and the wires sank into the shallow grooves. The wire was laid all the way to the window.
.
Li San used a hand drill to drill a small hole between the window frame and the wall, and then passed the wire through.
He got out of the window, ran the wire behind the rainwater pipe, and hung it all the way down. No one would notice!
His next step surprised Han Jindong even more. He took out a glass plate that had been prepared for a long time from the big bag, then opened several small bottles and poured some powder on the glass plate.
He looked at the wall while adding different colors.
At this time, Han Jindong realized that he was mixing plaster and wanted it to be the same color as the wall. So he had the foresight to hand Li San a glass of water. As expected, Li San smiled brightly at him.
After Li San mixed the plaster on the glass plate, he used an extremely delicate small scraper to scrape the plaster into the shallow groove.
After scraping for a short period, he picked up the hair dryer and blew the plaster that had just been scraped off.
The plaster dried quickly. He raised the desk lamp and carefully observed this small section of plaster.
He turned back and asked Han Jindong, "Brother Han, look at it, is the color correct?"
Han Jindong already understood what he meant, and after looking at it carefully for a while, he whispered: "Is it a little shallow?"
Li San nodded and continued to deepen the color in the plaster. After several adjustments, they all thought the color was consistent, so they scraped the plaster in the entire shallow groove.
Han Jindong was also able to get involved in this job and worked with Li San.
As soon as he got started, he felt that this was a delicate job that required great care.

Looking at Longmen Lane, in the shadow behind the Ministry of Foreign Affairs building.
Chen Zifeng and Ge Er sat together and looked around quietly. A brother slowly patrolled along the building. Occasionally, he also went to the front of the building to take a look to observe if there was any unexpected situation.
During this period, Chen Zifeng would stare at Ge Er from time to time.?
