"Lost?"

"I sent you seven cars, and more than twenty people took turns to follow you, and now, you tell me, I lost it!?"

In the Metropolitan Police Department, the director of the department held the phone, and the tic-tac-toe green tendons burst out on the door of his head, asking word by word, and his deep voice was like the depression of a volcano before the eruption.

"Yes, yes......"

Cold sweat broke out on the forehead of the captain in charge of the follow-up, and several subordinates next to him were all silent.

Unsurprisingly, they're going to be greeted by a storm of the Chief.

Ten minutes later......

The captain scratched his ears, feeling a little auditory hallucination, as if the hall chief's scolding was still echoing in his mind.

The subordinate shouted loudly, and he came back to his senses and asked, "Ah, what are you talking about, be louder." ”

"Are you still chasing?"

"Of course you have to chase, now, at this moment, set off for me, as long as they are still in Taiji Town, find them all, dig three feet into the ground, and find out!"

Unlike the angry director of the Metropolitan Police Department, Richard and the others were all happy, and the depression of the past few days dissipated, and their mood was much better.

"What's next?" Mandy pressed the headset and asked excitedly.

"Get off the train as soon as possible, get off at the next stop, and, let me tell you a little more, never talk about sensitive information in an unknown environment, and contact me when you get off the stop." After instructing Mandy, Bi Fang stopped speaking.

Mandy nodded, confirming the information with the people around her.

Whether it's a tram or a bus, there will be a fixed line, as long as someone is interested in a little checking, you can understand the route of Richard and others, so be sure to leave before the follower is deployed at the next stop.

Bi Fang stood on the hillside and looked at the road below.

This is directly in front of Dolphin Bay, which is surrounded by mountains on three sides, and the sea spreads over the beach, and further up, there is a high wall.

Above the high wall is a wide road, and the road is surrounded by low hills at both ends, so the road leads to a tunnel at both ends.

Dolphin Bay is a lowland, with sidewalks next to the road and a sandy beach leading to Dolphin Bay next to the sidewalk, which can only be reached by walking down the stairs, like an ancient city wall.

Bi Fang wanted to arrange a few camera points directly above the road, with a wide field of vision, looking down from a height, there was no better observation point than anywhere, the only problem was.

Due to the tunnel, surveillance is arranged at both ends, and if you want to go to Dolphin Bay Beach, you must cross the road, which is bound to be exposed to surveillance.

Nowadays, surveillance cameras have long been all over the streets and alleys of major cities, and the surveillance footage of street shops such as traffic stations, ATMs, jewelry stores, and fast food restaurants can collect pictures of passers-by's faces.

Due to their low price, surveillance devices can now be found even in remote parts of the world.

Although Taiji is not a big city, some critical sections may be monitored, and the possibility of damage is very small.

It's not a matter of the bright side or the dark side, and whoever does it will seem very unusual.

In the most sensitive places of the residents of Taiji Town, several high-definition cameras are arranged.

What do you want to do?

What is your purpose in pretending to be this, who instructed you, what is your motive, and have you obtained permission from the relevant authorities?

Did you allow you to send it? Who is behind you, what do you want to do, what do you want to subvert, what do you want to destroy?

Can't answer?

Don't say that we arrested you blindly, it is all justified, in our book, you can be locked up for 28 days without evidence!

Ahem......

Bi Fang pressed the cap and retracted his thoughts.

Unfortunately, these monitoring is indeed troublesome, but it is not a problem for Bi Fang.

To be on the safe side, Bi Fang often assumes that he has stepped into the range of surveillance cameras, and uses some covert or interference methods to reduce the possibility of being detected.

Caps and masks are sufficient.

When you go out, you should avoid wearing a mask or adopting weird disguises.

Bad Hollywood cinematic disguises can quickly get third parties to notice you.

The real cleverness is often the simplest, and a hat or hood is sufficient.

Bi Fang squatted on the hillside, watched the vehicles in the tunnel appear, and quickly drove into another passage.

There are few people here, and soon, Bi Fang found a gap period, he turned on the flashlight, took advantage of the fact that there was no vehicle passing, jumped down from the five or six meters high mountain, landed behind him and quickly slapped off the fallen leaves on his body, and held the flashlight to the roadside monitoring.

Many cameras with auto exposure automatically shrink the aperture in bright light – pointing a flashlight or LED light directly at the lens can effectively reduce the pixels of a photo.

Bi Fang had gone through the overall plan as early as when he was on the mountain, calculating the time of action to ensure that the sun was always behind him when he met the camera.

Then blurring the opportunity of the camera, Bi Fang quickly wanted to the edge of the road, pulled out the telescopic ladder, and came to the bottom of the surveillance.

He pulled out the razor blade pressed against his tongue and quickly inserted it into the rubber sheath behind the monitor, twisting it from side to side so that it passed through the braided shield and touched the hard metal core.

The core signal of the surveillance camera is transmitted by a copper conductor in the middle of the camera, which is encased in a sheath made of metal and rubber.

Contact between a steel blade and a copper conductor can cause a short circuit that temporarily interrupts video transmission.

Inserting the blade into the rubber sheath behind the monitor, passing through the braided shield, and touching the hard metal core, the aluminum foil shield, will cause the monitor to generate static interference and interrupt the transmission of images.

It's also very easy to get back to normal.

Remove the blade and the signal will return to normal.

Steel blades are easy to find, even the most ordinary guest rooms will have razor blades in them, if not, then go and buy a box.

Such road monitoring must be guarded, and if something is wrong, it will definitely come to check.

But Bi Fang didn't want to wait for him to come and check, once the monitoring was broken, no one would come to fix it in a few days, what he wanted was to make the other party not realize that there was a problem.

Five minutes.

Bi Fang's time for himself.

From the discovery of the monitoring personnel to the monitoring of the problem, to the call to inquire, and the record, it is about this point in time.

If the staff neglects their duties, this time can be longer, but Bi Fang will not pin it on such a fluke.

As long as the goal is completed within this point in time, all this he does will not arouse anyone's suspicion.

In the same way, after interfering with the monitoring static electricity from the mouth of another tunnel, Bi Fang quickly took out the "stones" in his backpack and placed them under the road railing.

It's very unremarkable here.

Right in front of Dolphin Bay, you can shoot as much as you want, everything everyone has done here, will be recorded, and nothing will be missed.

At this moment, the sound of cars whistling in the tunnel was heard again, and Bi Fang quickly climbed over the railing, lying on the edge of the sidewalk with his hands, and the whole person only relied on the strength of his fingers to hang himself on the high wall.

When the car disappeared over the road, Bi Fang stepped on the front, quickly pulled the railing with the help of a short suspension in the air, and turned over again to arrange other stones.

These are small rocks that are inconspicuous, but because of their size, they can't fit too big a battery, so the power is limited.

Similar to installing covert equipment, there are "hard installation" and "soft installation" expressions.

The former uses the parasitic power of a power source, such as a TV or electrical outlet, to temporarily install the device.

The latter can be as simple as putting the device inside a tissue box.

"Hard installing" requires a lot of time spent on the target, but there is never a need to dive back in to repair the equipment again.

And once a device runs out of battery or storage space, sometimes the person setting it up may need to take the risk of coming back to deal with the "soft-install" device.

The choice of option can only be concluded after weighing a number of factors, such as the location available, the length of time to monitor, and the achievable sound quality.

While it is possible to make a usable monitoring device with just a mobile phone and a pair of headphones, if it is installed in a bad place, the results will be poor.

After arranging the top, Bi Fang jumped on the beach, quickly dug a hole, and buried a "boulder" in it, only a small corner protruded, which looked like a normal rock, but one corner was exposed.

Bi Fang spread some dry fine sand to avoid being seen that the place had been dug up.

Minutes and seconds passed.

Bi Fang's movements were very fast, and he pulled out the blade after the second monitor, and the five-minute alarm went off just in time.

In a certain room, the dense surveillance made people dizzy, and the two screens that were originally full of snowflakes returned to normal again, and the car drove by, without any abnormality.

The staff who was about to call for repair and inspection was about to press the button, and when he saw this situation, he put down the microphone and registration hand, and picked up the mobile phone again.

It's business as usual.

Bi Fang in the forest clapped his hands and breathed a long sigh of relief, the most difficult part was solved by him, and the rest was simple.

There's a problem, though.

Bi Fang rummaged through the backpack with the "stones" gone: "There is no equipment." ”

The size of the backpack is limited, and it is already the limit to fit three "boulders", small stones and some branches, and it is difficult to carry more, and it is also inconvenient to move in the forest.

Previously, I worked with Mandy, Keko, and three groups, and I could bring four or five large boxes at a time, and three trips back and forth, that is, more than a dozen large boxes, and the progress of the work in one night was very fast.

can be replaced by Bi Fang alone, it can only be a backpack, and he can't go back to equipment.

Climbing the wall of the hotel during the day is too conspicuous, and it is easy to be remembered, there is more surveillance in the city, and it is impossible for everyone to be plugged in with a blade, Bi Fang should try to avoid the intersection with Richard and others in front of the public eye.

"I'm going to have to make some of it myself."

Bi Fang held the map, there were still many places on it that he hadn't visited.

Just as they were thinking about a solution, Mandy's connection came again.

"We got off, and now?"

Bi Fang groaned for a moment and said tentatively: "Play? ”

"Are you kidding?"

"That's all it can be." Bi Fang was helpless, he could command Mandy and the others to throw them to the end, but he was not a god, and he completely made them transparent in broad daylight.

With such a large team of foreigners, the police can quickly re-search for Richard and others through surveillance, unless they are broken into pieces and their whereabouts are reduced.

But this goes against the original intention of Richard and others to come out to attract attention, and Bi Fang is not able to guide everyone.

It's enough to give vent once.

"After Shuwei, they will come to you for revenge, and now I think you should make some weapons." Bi Fang said calmly.

Shuwei is a tree, but the experience of Richard and the others when they first came to Yuben is still vivid, maybe the other party will be angry and will rush up and beat them.

"Weapons?"

"You have a lot of cameras around you, right?"

"Nonsense."

Don't forget what they're here for, how could they not have a camera?

"Then you can try converting the camera into a taser."

"Tasers? What is that? ”

"Stun guns."

Faced with Mandy, a layman, Bi Fang changed to a simple and easy-to-understand vocabulary.

"Camera...... Stun gun? Did both of these words turn out to be polysemy? ”

Mandy looked at the camera on the seat next to her, picked it up and looked at it for a long time, and took a few pictures of the station click.

Well, clear and good-looking.

"How do you change this thing?" Richard and Jarrett, two older molecules, are even more incomprehensible, and they feel very hot when they hold the camera.

The camera was changed to a stun gun.

What black technology?

"Don't worry about it so much, just do what I say." Bi Fang waved his hand and walked down the street again, now he was going to the supermarket to buy something.

Whether it's an ordinary person or an agent, it's important to choose a non-lethal way to defend yourself.

However, ready-made tasers are not easy to buy, let alone Richard and others, and it is impossible for others to sell them if they buy them.

It's not that hard to change the camera to a taser.

The power that had been powering the flash was directed to two raised screws by rewiring the wires was enough to temporarily paralyze the attacker.

The opponent who is hit is likely to fall to the ground and become incapacitated within a few minutes.

The current of 120~380 volts can pass through tissues and nerves, generating static electricity in the body, which can interfere with the communication between the brain and muscles.

The result is impaired kinesiology and involuntary contraction of muscles, making it a powerful, non-lethal form of self-defense.

Mondstadt's hand trembled at this.

Photography is not separated, and as a photography assistant, Mondstadt never thought that his hands were so hot.

"Now, listen to me, take apart the capacitor of the camera, and then remove the battery."

Film SLR camera, the price of this thing is ridiculously expensive, but in the face of a small life, everything is worth it.

After all, there is only one life.

Bi Fang began to teach knowledge step by step, which was impossible for ordinary people to know.

In the first step, empty the capacitor.

Before disassembling the camera, remove the battery, press the flash button, and drain all the power stored in the capacitor to prevent accidental electric shock during assembly.

If the capacitor is not discharged properly, the risk of injury is very high.

The second step is to take the camera apart.

Remove the camera housing, remove the circuit board, flash, film, and disassemble the flash assembly and circuit board.

"Screwdrivers, and wire strippers? Small pliers will also work. ”

"Yes!"

The electrical specialist opens his toolbox and takes out the tools inside.

After Bi Fang's reminder, he also knew what to do.

As an electrical expert, he felt that changing the camera to the taser was a path he had never envisioned before.

A lot of times, it's not that people don't know how to do it, but they lack an inspiration, and if they don't have some training that ordinary people don't know, they can't think of this way at all.

Under Bi Fang's reminder, the electrical expert quickly understood the point, and according to Bi Fang's instructions, he left a small section of film.

He carefully stripped the insulated wires from both ends of the wire. Wrap the end of the wire around the tip of the screw. Screw the screws into the camera case from the film cassette.

Then wrap the other end of the wire around the binding post of the capacitor and secure it with electrical tape.

In this way, the camera's current flows from the battery to the two screws, and if you stab it at the enemy, you can achieve the exact same effect as a stun gun.

The final step is to reassemble the camera, restore the circuit board, and plug the wires around the board.

"There is also a need for a security mechanism."

"I see."

The electrical expert immediately understood why he had asked him to cut a piece of film, and he inserted the cut negative between the battery and the battery end post, so as to prevent accidental discharge of the modified camera.

Finally, the shell was put back on, and the whole looked exactly the same as the original!

But the inside is completely different, no one would have thought that the "camera" in the hands of a tourist is actually a taser that can easily stun people!

"Bi Fang! You're a genius! The electrical expert shouted.

"When you use it, you can use an assassination motion to drive the screw into the opponent's flesh. A collision can cause significant vibrations and discharge, but if the device can't be discharged, piercing the skin should also cause enough damage to the attacker to escape. ”

"This thing is dangerous." Bi Fang exhorted with a serious expression.

If it weren't for the fact that it wasn't for the accident of Richard and the others, he wouldn't have been able to teach this kind of thing.

Making a simple taser is much more dangerous than it seems, and the discharge can cause severe incapacitating shock!
