"Thanks for the donation of 5,000 yuan and 100 yuan, welcome to visit us next time!"

In the supermarket, the sweet-voiced clerk squinted at Bi Fang, who was loading bags. Bi Fang nodded and rushed out carrying two big bags.

The special monitoring equipment was not enough, so Bi Fang needed to make a batch of his own, so he went to the supermarket and purchased a large amount of milk, vinegar, and some snacks.

Something seems to be wrong?

If Bi Fang was live broadcasting at this time, there would definitely be a large number of live broadcast viewers complaining like this, because what Bifang bought is really normal.

Are you sure you are not here to purchase daily necessities?

Except for the large amount of milk, which didn't look like it could be drunk during the trip, the rest was a bottle of vinegar. Well, maybe I like to eat sour food. The rest was filled with potato chips, happy water, biscuits, and jelly.

.....

Anyone who sees these products will not think that they can make anything special. They are simply necessary survival materials for a fat homebody.

It turns out that behind the wild man is actually a happy homebody!?

Of course it's impossible.

Bi Fang poured all the things he bought on the hotel sofa, took out a small basin, opened the milk lid, and poured all the milk into it.

The purpose of his going to the supermarket was actually only two things, milk and vinegar.

Cameras are everywhere - always assume your actions are being filmed.

The rest of the snacks are all designed to cover up the existence of these two things, so as not to appear too purposeful and arouse suspicion.

Of course, most people would not think of milk and vinegar, but it is better to be cautious. In the eyes of people like Bifang, they are the best materials for making disguise tools.

The milky white milk floated with a small amount of foam, and Bi Fang poured almost a liter of milk into the container.

Bi Fang tapped his chopsticks along the edge of the container to disperse the foam. He put it into the microwave in the room, looked at the power instruction sheet of the microwave, and adjusted the time to five minutes to start heating.

Higher-end hotel suites are also fully equipped with furniture and appliances, and some even have private kitchens.

Five minutes later, Bifang took out the steaming but not boiled milk, with a thin layer of "milk skin" already condensed on it.

Open the vinegar bottle, Bifang takes a stainless steel spoon and adds eight spoons of vinegar into the container filled with milk, while breaking the milk skin and stirring continuously.

When the mixing is completed, a large amount of floc sediment will wrap around the handle of the spoon.

Pick up the sediment, bring the handle of the spoon to eye level, and pinch the flocculated material, which is sticky and continuous.

very good.

This is what Bi Fang wants.

If you want to hide valuable data, keys or surveillance equipment such as cameras and microphones, you only need two common ingredients in the kitchen: milk and vinegar.

After heating and filtering, the casein in the milk solidifies into a gel-like plastic-like substance. The mixture of the two can be molded into any shape and can reach a clay-like consistency after drying.

This substance is ever-changing and can be shaped, colored, and simulated into the shape of rocks, bricks, logs, or anything else, making it a preferred intelligence receiving point and ideal for camouflaging valuables or surveillance equipment in certain environments.

The only thing you need to pay attention to is that when heating the milk, do not let it boil, otherwise you will not get filaments, but flocs.

The isolation of DNA proteins in high school biology is essentially the same method.

Bi Fang took out a spare short-sleeved shirt, covered it under the container, poured it into the sink, and filtered out the silky mixture.

In actual operation, with 500 grams or one pound of milk, you can make a "milk plastic ball" the size of an egg, which can hide a miniature camera.

Having camouflage is not enough, you also need cameras and microphones.

These are also not difficult for Bifang.

When he first carried out the mission, he thought that he might not be able to bring too much equipment, so he asked Richard and others to buy quite a few baby monitors.

Any computer store or large supermarket will have one, and it only needs simple modifications to turn it into a hidden camera.

Bi Fang only needs the inner parts and throws away the entire outer shell.

He removed its components—the transmitter, battery pack, and camera lens—but did not cut the wires connecting them.

Then insert a toothpick into the camera lens, stick the "special plastic" you just obtained on the lens, and shape the "plastic" around the lens into the shape of a rock.

At that time, as long as the toothpick is pulled out, an imperceptible pinhole will be left in the original position of the toothpick, and the camera can monitor through the small hole.

Bi Fang poured out some vinegar, mixed it with an appropriate amount of milk, and stirred it. The color soon turned into brownish gray, which is the "pigment" for dyeing.

Paint the rock a neutral color or trace a special texture of the target exterior landscape, put the transmitter and battery pack into a waterproof sealed bag, and finally connect the "rock".

At that time, the lower part can be buried in the soil. It does not need to be too deep. Too deep will cause the signal transmission to fail. Finally, place the camera so that it can capture the desired picture.

To ensure that the camera's "viewing angle" was in the proper position, Bi Fang waited until the last moment to remove the toothpick and used the angle of the toothpick to measure the field of view.

The probability of such a lens being discovered is very low.

Even if it is discovered, dismantled, and exposed wires, in the eyes of ordinary people, it is just a waste, buried by wind and sun.

During the installation process, you can also spray glue on the rock lens, and cover the rock lens with the soil collected on site as another layer of camouflage, which is almost foolproof.

A microphone is also required.

It is relatively simple to hide a voice-activated recording device in a target room or car, but without amplification equipment, it is unlikely to obtain effective intelligence.

A complete monitoring system requires a microphone to amplify the sound.

In the absence of specialized tools, mobile phones, audio jacks and headphones can be converted into effective monitors.

The difference between the two is extremely simple, their functions are exactly opposite.

Bi Fang took apart the earphones he bought at a cheap grocery store and exposed two conspicuous wires, one red positive wire and the other black negative wire.

Simply switch the polarity of two wires to change the functionality of the device.

Microphones and speakers are essentially the same instrument, and any speaker—from the earbuds on your headphones to the stereo system in your TV—can be transformed into a microphone in just a few minutes.

Speakers convert electronic signals into sound, and microphones convert sound into electronic signals that can be processed and amplified.

Bi Fang cut the output end of the speaker wire, connected it to the audio jack, and connected the audio jack to the photography equipment he had just made.

Essentially any small recording device can be used this way, but a cell phone that is muted and set to automatically answer has two additional advantages.

That is, it is possible to intercept intelligence in real time without taking the risk of returning to the target location to recover the equipment.

This bug installation technology is highly adaptable.

It's a pity that Bi Fang doesn't have many mobile phones.

Bifang also taught this trick to Richard and others, and asked them to install one on their cars, so that they would not be aware of it being sneaked in.

Simply deactivate any of the vehicle's rear speakers and plug its wires into a recorder or phone to assemble a vehicle monitoring device.

In public places, earplugs can also be hung in coat pockets and used as covert intelligence detection stations.

Sounds, images, and disguises were all in place, but in just one hour, Bi Fang once again made a batch of usable surveillance equipment.

He put on his backpack and continued to work today.

night.

Bifang, Mandy, and Keke came to Dolphin Bay again.

Although they had followed Bi Fang's instructions and changed hotels, this still did not trouble Bi Fang. It was even easier because this time the hotel had a balcony and no longer had a glass curtain wall.

Just under the watcher Yuan's eyes, Bi Fang brought the two people out.

Perhaps because the dolphin season is approaching, there were a lot more people in Dolphin Bay tonight.

Large firewood has also been piled up on the beach, and it looks like there will be a grand bonfire party tomorrow night.

The mission cycle is much longer than Bifang imagined. Survey the terrain, make plans, and observe patiently.

"Two teams of people just came from the tunnel, did you see them?" Bi Fang tilted his head and asked Mandy and Keke.

The two nodded, indicating that they had also seen it, and it was still a very bad sign.

The two groups of people ran up the mountain as soon as they got off the mountain, shaking their flashlights constantly and moving very quickly.

They want to leave as early as possible and start work.

Richard told Bi Fang that when they first came to Japan, they also met this group of people, and they would carefully look at the broken branches.

Usually only when there are dolphins in Dolphin Bay, they will go up the mountain to check, just to see if anyone is following and filming.

Bi Fang had already encountered a dolphin last night, and everything seemed inevitable.

The center of gravity of Dolphin Bay is on its right side. Bi Fang and the other two people placed their equipment on the left side of Dolphin Bay last night, where it is easier to enter the sea and observe.

Today, Bifang placed most of his equipment on a tree with a wide view. The observation point is higher and he has an unobstructed view from top to bottom.

Mandy wears an infrared camera on her head, also in case someone suddenly appears.

Not only that, they also have professional underwater divers who are responsible for underwater inspections and conducting carpet searches under the water. Bi Fang does not want them to discover those devices.

Underwater sound detectors, underwater cameras, underwater infrared cameras, these are the results of their efforts all night long. Bifang and Richard want to understand everything that happens here and have a full three-dimensional experience.

They want to hear every sound the dolphins make and every word the fishermen say. Bi Fang's efforts are not only to reveal the massacre, but also to record something that can change people's hearts.

Last weekend, the long and sad cry of the humpback whale echoed in London's Trafalgar Square. The overwhelming sadness was like a gush of cold water, overwhelmingly flooding the square, covering everyone.

Thousands of demonstrators demand an end to the killing of cetaceans.
