Uh, why does he know? Anyway, among the spies in the island city, he observed at least fifteen. It's also to blame that these old people didn't go directly into the house to search, if they went into the house and searched for their observation records that were clearly placed in the drawer on the windowsill, it is estimated that they can find at least six enemies in the island city.

Well, scare them a bit. After making sure that the listening equipment in the bedroom was not turned on, Xiao Chu took it down and took a slight look, hehe, it was really backward, and he still used an old-fashioned bugging device with an antenna.

Then he took out the special equipment he bought from the Electromechanical City, a sticky note that was only the size of a fingernail and a millimeter thick. Yes, it's a bug, with the latest out-of-the-box antenna technology, plus the whole thing is powered by a flexible metal plus a small layer of crystal battery. The most amazing thing is that this thing also has a layer of photovoltaic coating, as long as there is light, it can be charged by itself, and it can be used overnight without a sunny place. As for the eavesdropping device, it is the innermost layer of resonance film, as long as such a small thing is attached to the glass or the edge of the table, within a three-meter monitoring range, the wheezing sound can be transmitted back.

In addition to the lack of sound quality and fidelity, other aspects are not the product of ordinary technology at all. The problem is that this thing is only an international mid-level eavesdropping device, the highest grade is said to be thinner, and it is completely transparent, and it is absolutely indistinguishable to ordinary people if it is attached to any glass, and the weak electromagnetic propagation, the most advanced microwave detection equipment is difficult to determine that this is a bugging.

Well, it's easy to use and not expensive, this thing looks like black technology, but in fact, it only sells for 158 US dollars, Xiao Chu casually took out two small yellow croaker, and got a lot of special equipment back.

As for why he was able to buy these things, well, there are a lot of spies who follow and observe, and the places they often go to always know, and even the hidden way of trading can find a clue, but this time it is the first time he has bought it alone.

After entering the mechanical and electrical city, I found a hidden stall, the owner was a radio repairer, and this almost lost trade can only be found in this place.

Without saying a word, Xiao Chu directly took out two one-pound gold bars from his sleeve, and then pushed them to the boss's chair.

The boss didn't say anything, but looked around, and when he saw that no one was paying attention, he checked the two gold bars, stuffed them into his pocket, and then took out a box from a large pile of electronic parts behind him and put it out.

According to the price of the goods, this is the information that Xiao Chu came to after observing this stall for several days, no matter who comes, if this stall does special business, then only gold will be accepted, either small gold wires, or gold bars. Like Xiao Chu, who smashed down two catties of gold bars directly, he was really a high roller.

In fact, the underground world is completely different from what the Luthers in the upper world imagined, and those who are still connected and coded are purely sick. Because as long as the people who know these hidden trading places can always find them, and the layman who doesn't know them doesn't even have a stepping stone. It's safer to only do business with acquaintances, but acquaintances are not reliable, and you ask for a lot of passwords, isn't this an obvious way to tell the seller that there is a problem with this person?

It's too late for people who really need these things to hide their identities, how can they introduce others. So the only ones who can find his storefront and find the right way to trade can only be those rats in the underworld.

It's just that the young age of this mouse surprised the boss a little.

Ten SMD bugs, 10 LED tube monitors, 10 camouflage surveillance plus bugs, 2 sets of signal receivers, 1 set of signal adapters, 2 USB drives exist in 2 systems. One set of vibration recorder, one set of microwave sonar detection sensor. Together, it is less than the size of a biscuit box, and it is worth the price of a kilogram of gold.

Cash to buy a spray gun for painting, and then a set of drones, plus a set of remote control monitors and wiring on the surface.

In addition, some metal elements and metal wires have been added, and a set of micro-conductive Tesla coils need to be made, and this thing is used to detect the conductor, which is called an accurate, and it will burn out for you in minutes.

In just a few hours, he determined where the people who were watching him lived, the house downstairs was being rented out, and the owner had moved to the United States, supposedly emigrating. Xiao Chu was thinking about whether to buy it with money, but he found out that he had rented it out three days ago through the real estate agency system in the community.

Turn on the microwave sonar detector, stick it on the floor, and then adjust it to medium power, and with two soft bangs, the layout downstairs will become a group of data displayed on Xiao Chu's computer.

The rest of the house is almost empty, except for some clearly furnished layouts.

Only there were two people in his bedroom, a man, literally sleeping in bed, and a woman listening to something with headphones, but she was doomed to disappointment. The bugging device was placed in Xiao Chu's hand, and except for the sound of the mouse clicking, nothing else could be heard at all.

Xiao Chu opened the window and released the modified drone, which circled around their building and sent back a set of video data silently. Retracting the drone, Xiao Chu began to observe the video data frame by frame.

The high-definition 25 million pixel self-sensing infrared camera shoots the video, and the hairs on the human face are clearly visible within ten meters. And this value-added modified drone has also been modified with micro-sound and video transmission, a set of video processing is directly stored in a few T's memory, and a set of video is transmitted to the control end in a simple format.

Micro-UAVs worth more than 100,000 can be said to be an artifact in modern urban warfare. However, the price also directly made the buddies who play drones vomit blood. But now they can't afford to buy drones with this performance, even if they have money, no. You know, this degree of modification is already the effect of tactical UAVs, and even more advanced than the tactical UAVs equipped in the special forces. After all, the time period required for those drones from finalization to trial to assembly is really a bit pitfall.

And now the speed at which these covert devices are updated on the black market is measured in weeks.

Shout, women are still beautiful, men sleep with their heads covered, they can't see, but you don't have all the curtains, are you doing underground work?

I looked at the time in the lower right corner of the monitor, and it was almost time for lunch.

took out the phone to contact Lan Beibei, and learned that she was at school, so she made an appointment to go to a hot pot restaurant near the school, saying that there was something important to say.
