"It's snowing."

Tang Chao landed on the roof of a building again, looked at the sky that had been completely covered by dark clouds, and the scattered snowflakes that began to fall, he felt very good.

The weather forecast says that there will be heavy snow and strong winds today, which is the perfect weather for trouble.

There is a possibility that there will be footprints, but when the snow is heavy and the wind blows, anything can be blown flat and covered.

By the time the other party came to the door, he had already returned to China.

He's not an agent who has been lurking here for a long time, he's just a passing sci-fi assassin.

He leaped over more than a dozen rooftops in a row, and even some two-way lanes that were not too wide also leaped over, until he met a two-way four-lane on the path he was on.

It's not that you can't jump over a distance of more than ten meters, but if you want to jump such a distance, the chance of being found will increase, so I gave up.

However, he looked around, and returned to another building to prevent anyone from spotting him, the Assassin, coming down from the outer wall of the building.

There was an alley at the back of the building, and it was so dark that no one passed by at night, so it was perfect for him to go downstairs.

The buildings in this area are also traditional Maozi buildings, with various patterns, horizontal strips, and relief decorations, which are very easy to climb.

By the time he came down and walked to the place where the light could shine, the small snowflakes had turned into goose feathers, and the cold wind was blowing.

Look at the pedestrians on the street, each wrapped up in a down jacket, wrapped a scarf, put on a hat, and wrapped himself tightly, not to mention seeing the face, it would be nice to see the eyes.

Since it's all like this, Tang Chao naturally has the same example.

His coat was the kind with a hood, so as soon as the hood was worn and the collar was erected, he was also "fully armed".

The first target was not too far away, and there was a few hundred meters in a straight line, and the crow that was tracking the other party had landed, and released an insect monitor to follow the man's room, while the crow found an eaves outside to hide, and continued to watch the gate.

After all, the wind and snow are still quite big on the equipment.

The other crows were also tracking the target, more than half of them had already returned to their residences, and only three of them were still hanging outside, which was too unfriendly for the crow reconnaissance plane, Tang Chao felt uncomfortable looking at the three surveillance screens.

It's too shaky.

Tang Chao had already given the order, if the wind and snow continued to increase, big enough to threaten the safety of the bionic crow's body, and the other party had not returned to the residence, the mission would be aborted.

At that time, the tracking and reconnaissance mission will be turned into a safe evacuation mission, and the crows need to find a relatively safe place nearby, and then enter energy-saving sleep mode, and when the outside world is suitable to fly again, they will return directly.

Because the wind and snow are stronger, there are fewer pedestrians on the road.

Every pedestrian wrapped himself tightly and walked in a hurry, and the sci-fi assassin Tang Chao who passed by was also a "passerby", so he was also in a hurry.

Soon, he was downstairs at Target One, an apartment building.

The buildings in this area are relatively old, it should be old, and the architectural style has a kind of old hairy taste, according to the picture observed by the crow outside and the insects passing by, the management inside is not very good.

If you are a person with sufficient funds and a certain pursuit of quality of life, you will basically not choose here, but this situation not only meets the requirements of some people who live a restrained life, but also meets the needs of some people.

People with ulterior motives.

Anyway, it's a bit shabby and dirty, so I don't care who lives in it, and I don't even have cameras here, and I don't care who comes in or out, just pay the rent.

Tang Chao also found a lot of Russian prompts.

[Take care of your belongings, we only provide the house, not the security!] 】

[In the event of a power outage, check first to see if you forgot to pay the electricity bill, trip or the room line is aging, don't call me as soon as possible!] 】

[Take care of your own fire source, if it causes a fire, the fire cost will be paid by yourself!] 】

You can change the color of the wall, but it's best not to change its shape, or you'll face a hefty fine!] 】

That's probably what it means, in addition to the responsibility of dumping the pot, the rest is to ask the tenant to protect the house.

After all, this kind of old apartment is profitable by cheap rent, and if the house is destroyed by the tenant, then the repair cost will definitely cost a lot of money.

As the owner of a cheap apartment, he didn't want to pay for it.

On the mission's side, because the insects followed, the crow circled around the building a few times as he landed and stared at the gate, and found that the agent's apartment was on the fifth floor, with two windows, one large and one small.

This height is neither high nor too low, and with all kinds of private buildings on the windowsill, it is still very easy to think of a way to go up.

So even if there is a private building on the windowsill, the protective net is not falling.

Let's not talk about the windows of other homes, it's messy anyway, and the spy's windows are a bit "designed".

It's not that his windows aren't messy, it's chaotic, other people's houses are messy, that's really messy, for rock climbing and parkour enthusiasts, it's not difficult to climb up or down, but the spy's window is different.

Although his windows look messy, there are some messy places piled up on them, and protective nets are installed, and there are even some spikes, rusty wires, and tattered shelves sticking out of them, so that people's first impression feels that they are used to prevent thieves climbing windows.

It's just that in Tang Chao's opinion, preventing thieves is secondary, it is true to guard against some emergencies, and even at critical moments, the other party can use those messy things to create some small dangers and make himself run faster from the window.

After observing the outside, he observed the spy through the perspective of an insect, and when he saw that the other party was eating fast food and using the computer to communicate with some people, he decided to go up.

If you don't go up, the bugs will run out of power.

There is no way, the size limits the power of the small bug detector, and this thing cannot be used at all outside, so it can only be used in the mode of forming an aircraft carrier and a carrier-based aircraft with a relatively large detector.

Like how they go with crows.

The crow is certainly not obvious outside, but when it is inside, it must be very conspicuous.

Of course, whether you can enter the room or not depends on two words.

All of this has to be paired with smaller detectors.

The bug detector is not easy to use outside, but when placed indoors, it is definitely one top and one is easy to use.

There is generally no complex air movement indoors, which is very beneficial for the movement of the insect detector, as long as you avoid the air supply track of electric fans and air conditioners, you can fly or climb anywhere else.

And it's not that the power is limited, if you can find a good angle, it would be good to monitor directly statically, which is definitely more power-saving than monitoring in motion.

This is the pattern of the bugs that are now being monitored indoors.

But that's it, it doesn't have much power, if it weren't for Tang Chao arriving, the crow would have planned to move and fly to a place with a gap to release another bug detector relay.

At present, this amount of power is enough for Tang Chao to find the spy's residence, and then provide a picture of the spy's reaction when Tang Chao slid the door and picked the lock.

"Wow~"

When Tang Chao was about to enter the door, someone happened to come over, and the other party was also about to enter the door, so Tang Chao didn't even pull the door, and after the other party opened it, he followed in.

The other party was tightly wrapped, and the snow on his body was the same as Tang Chao's situation, so what he did after he went in, Tang Chao did the same.

It looks like he's familiar with this place.

The other party didn't do anything, and ran upstairs directly, without even pulling the snowflakes on his body.

"Cow Pie!"

Tang Chao hurriedly followed.

These people don't play by the routine than him.

The man turned a corner when he reached the second floor, and Tang Chao ran to the fourth floor according to the man's pattern, and then began to go upstairs softly.

Aided by a nano-combat suit, his specially structured soles absorb volume well, allowing him to walk like a feline predator.

As he went upstairs softly, the worm continued to provide him with footage, and the spy had eaten half of it, but had stopped eating it, but put it aside, and used the computer intently.

Golden opportunity!

Tang Chao came to his door lightly and found that it was a simple mechanical security door.

Also, this is not a high-end apartment after all, there is not even a camera in the corridor, and there will definitely be no electronic smart door without a camera.

And how to say it, in the Internet era and the intelligent era, smart door locks are really not necessarily as secure as mechanical door locks.

The essence of smart locks is mechanical locks, but they are equipped with motors, which support electric unlocking, and then integrate modern unlocking methods such as fingerprint recognition, passwords, door cards, Bluetooth, and mobile phone apps, which become smart locks.

If the previous mechanical lock only needs to be guarded against, there are more places to guard against the smart lock, in addition to the original mechanical lock module, but also to prevent the circuit, system, authenticity recognition and other aspects.

For example, some smart door locks known as facial recognition can be opened with a photo swipe, which is faster than trying facial recognition in person.

The keyword of the most broken news reports about smart door locks is "small black box", which is the simplest and crudest way to crack smart door locks.

This small black box is actually a miniature high-intensity electromagnetic pulse device, which can form a strong magnetic field and destroy the surrounding electronic equipment.

When the smart door lock encounters such a strong voltage and current, it will cause the chip of the circuit board to crash, and most of the smart locks on the market will restart when the default chip crashes, and it will be automatically unlocked after restarting.

Therefore, those inferior smart door locks have no power to fight back in front of this small black box.

Fortunately, many mainstream door lock companies are now paying attention to this problem, 85% of the door locks in the detection can prevent small black boxes, basically improve the circuit design, increase the voltage stabilization module, to prevent the impact of high voltage.

Therefore, everyone should choose regular channels and big-name manufacturers when buying smart door locks.

Ahem, of course, this is what the big brand smart door lock manufacturers say.

They will directly use the small black box for security testing at various security door exhibitions.

How to test it, is to put some inferior door locks and high-end "friend" door locks, as well as their own higher-end smart door locks to test together.

The result of the test is, of course, that the inferior and high-end "friends" are garbage, which can be opened at the touch of a button, and only their own smart door locks are the most cowdozen.

In fact, this thing adjusts the power of the small black box, so that the power of the small black box just reaches the standard of opening other locks, and then it is a little worse than the security power of your own door lock, so that you can measure the perfect result.

In fact, selling smart door locks is selling community security.

After all, the community where the user who buys a high-end smart door lock will not be bad, the access control at the entrance of the community, the security guards who patrol the community uninterruptedly and the cameras that can be seen everywhere, and even some users will follow the camera at the door of their own house, so that the security is greatly improved.

So this kind of door is not to say how much the security has improved, but that the thieves are less coming.

In addition, what fingerprint lock, generally low-end fingerprint recognition uses LED light into the finger, diffuses in the finger and is detected by PD from the fingerprint, combined with capacitive fingerprint image acquisition.

To put it simply, it is to shine your finger with a lamp, and the machine will compare it with the fingerprint in the memory after seeing it clearly.

This kind of door lock only needs to take a little wax and glue, and reproduce a fingerprint to identify the door lock through these low-end fingerprints.

Wax is 1 yuan, glue is 8 cents, and a bottle of glue can make 200 fingerprint films, each less than 1 cent.

Better smart lock manufacturers will add a live sensor to the fingerprint recognition, which can judge the temperature and capacitance value of the finger to prevent the impersonation of the fingerprint mold.

The grip will also have an anti-fingerprint matte design to reduce the possibility of thieves collecting fingerprints.

But it can only be said that it is relatively safe, and the safest thing is to live in a well-ordered community, after all, the agents in the movie often do this kind of thing.

There are also those unlocked with long-distance APP, which is even more insecure for the Internet era.

In the past, thieves were required to commit crimes at the scene, and this kind of full unlocking may be solved by the thief drinking ice at home.

Find another partner, remote control partner to go in and steal things, it's just beautiful.

Even if it is hacked, it can not only control the status of the door lock from a distance, obtain the user's mobile phone information, and even reverse enter the manufacturer's server to obtain the mobile phone information of a large number of users who use the brand's smart door lock.

Then the fun is even greater.

The spy was of course very concerned about his own safety, so he used the highest level of mechanical locks, and even had his own modifications, so that even the landlord could not enter during the rental.

But such a door lock is difficult for Tang Chao.

I saw that his index finger wearing a black glove was close to the door lock, and when he touched the door lock, the tip of the glove index finger liquefied and flowed directly into the keyhole, and in the blink of an eye, a matching black key was formed.

Tang Chao turned slightly, and the door lock made a slight noise.

The worm had observed the whole process of the spy opening the door, and the lock of this door was very quiet, and even the door shaft was very lubricated, and it did not make a sound when pushed open.

Therefore, there is no such thing as in the movie where you carefully push open the door and make a loud friction sound to alarm the enemy.

And through the reality of the images sent by the worm at the same time, the other party really has nothing to ......

No,, the spy found him!

The spy who was still using the computer to type and chat quickly just now in the room was stunned for a moment, and it was obviously not caused by the conversation, and then he threw the computer, rolled over, then slammed again, and then rolled another roll, rolling directly into the bedroom.

The whole set of movements is like flowing clouds, like the wind and clouds, smooth and fast.

"Bang bang" twice.

There was a sound when the other party slammed the bedroom door shut.

The second sound was that Tang Chao saw that the situation was not good, and he entered the living room and slammed the door shut.

Then the coat, pants, and shoes instantly shrank and turned into a nano combat suit!

It's time to do what an Assassin does!
