Several Cossack mercenaries guarding the door, were looking around vigilantly. 2. Suddenly, I saw several figures in front of me approaching, and I immediately became alert. One of them held out his hand, and the smart bracelet on his wrist flashed. The other party also seems to have a sense, corresponding to the slight light flashing on everyone's wrist.

The flash is faint, but it is noticeable under night vision. The guards also saw it clearly, and the four people who came were all wearing gpnVg-18 quadruple night vision devices. Looking at the oncoming guards, these Cossack mercenary guards at the gate obviously didn't have much defense.

"Now, do it!" Sergey secretly turned on the emI jammer. Suddenly, the surveillance video image at the door was distorted and distorted, and the picture could not be seen clearly. Lin Rui and the others walked over unhurriedly.

"Hey, man, why did you guys get back?" asked a Cossack guard casually.

But the response he received was that he was suddenly twisted his arm and pressed against the wall, and then there was a stabbing pain in the back of his neck, and in just a few seconds he suddenly lost the strength to resist, and he collapsed, and fainted after ten seconds. Before he fainted, he saw the returning "companions" already carrying the other guards around him, dragging them to a secluded place.

The guard panicked, but the panic didn't last even a few minutes, and he himself fell into a coma.

"This thing is awesome. Lin Rui was also surprised by the high efficiency of this anesthetic.

"The projectile is not advanced, but this tranquilizer is supposed to be an improved third-generation product. Sergei whispered, "Aladdin, this guy can get anything. ”

"Nonsense, if you're willing to pay, he'll probably be able to get you even the raw materials for thermonuclear weapons. Shogan whispered.

Lin Rui gave Sergei a look. Sergei nodded, and once again turned off the emI jammer he was carrying behind his back. Video transmission was restored, but the monitoring room still asked them through communication, "Cossack XVI, is the situation at the entrance normal?"

"Normal. Sergei said in a deliberate whisper.

"Understood, it's just that there was a bit of a problem with the monitoring just now. Damn it, nothing seems to be going well tonight, over. The guard inside the surveillance room muttered.

"Over. Sergei replied in a low voice. After doing all this, they all breathed a deep sigh of relief.

"Sergey, prepare to open the lock, and the rest of the people are on alert!" Lin Rui said in a low voice.

Sergey immediately squatted at the door, took out the lock-picking tool from his pouch, and said in a low voice, "Hydraulic brake door, electronic induction door lock." Fortunately, this lock model is not the most difficult one. ”

He busily unwrapped the lock, his head down to check the wiring inside the lock. Sergey pushed the night vision device on his head and put a monocular magnifying glass on his eye.

"What is this thing for, for repairing clocks or for appraising jewelry?" Rose chuckled.

"It's for thieves. Sergei whispered solemnly, "There are three chipsets inside, and a set of key capacitors are used in differential circuits, so that the capacitors are called differential capacitors." In order to obtain the cusp touch signal in the contact circuit, this differential capacitor circuit is used to obtain the cusp pulse signal from the rectangular pulse signal. ”

"Damn professional thieves, I never knew you had to know that to be a thief. Rose was stunned.

"It's not a thief, it's a lockpick. Thieves are a profession, while lockpicking is a performance art. You should be honored to meet one of the best few lock picking masters in all of Europe. Sergei still struggled to change his tone, but his hands were not slow at all.

Sergey first attached wires to several electrodes on the board with several metal tweezers, mounted a small instrument on them, and turned on the instrument. The LCD screen on the instrument began to flicker, revealing different combinations of numbers.

"What the hell is this?" Shogan frowned, "You're using the brute-force method to crack the unlocking code, how long will it take to crack it?"

"That's right, it's still actuaries who know the goods. It won't be long, because the instrument is connected to the Köppen network via satellite. Do you know what a mainframe computer is capable of, and how long it takes to crack such a six-digit code?" Sergey whispered, "It's not like I'm working alone, it's a team. ”

Cobain's voice came from inside the headphones, "It's been received, and it's ready, and the results will be available in a few minutes." ”

Sergei shrugged his shoulders back, "It's our business, but it's a skilled job." ”

Looking at this guy's shameless smug appearance, the others were also speechless for a while. It is estimated that few people will be proud of being a thief.

A few minutes later, there was a soft "drip" and the hydraulic brake door moved silently to one side.

"It's done. Sergei whispered.

"This thing works. Shogan shook his head and said, "You did it yourself?"

"Pretty much. You can't buy it in the market unless you have another way to get it. Sergey put things away.

Lin Rui stretched out his hand to block the rose that was about to enter, and said in a low voice, "Be cautious." He took out a tiny speculum and peeked through the corner of the wall, displaying an image on the tactical computer. Then he nodded, "You can go in, but there is surveillance in the corridor below." Sergey, get the jammer ready. ”

"Understood. Sergei nodded, "Sneaky, it's like going back to the old ways." ”

"Don't talk nonsense, come in!" Lin Rui walked in front with a gun in his hand, and stopped near the corridor below. Putting down the gpnVg-18 quadruple night vision device, under the lens of the night vision device, it is easy to find the hidden monitoring equipment.

The general camera does not have an infrared light supplement, only a wide-angle fisheye lens is exposed, and it is an optical receiving device with CCD imaging behind, which does not emit infrared rays, but is difficult to find.

But a good camera can recognize a higher optical spectrum than the human eye, and the camera can capture near-infrared light that is invisible to the human eye, even very cheap white light cameras have this ability. Because the camera is equipped with infrared supplemental light, the near-infrared light that is invisible to the human eye is emitted, and it shines on the camera object like a flashlight, and can be imaged on the CCD, but it becomes a dark red monochrome image, which is not very clear.

The more advanced infrared light complement is a laser device, which also emits near-infrared light, but with more power and clearer imaging. The most advanced is a special CCD that is very sensitive to near-infrared light, which can capture the infrared rays produced by the human body itself without supplemental light, similar to night vision devices, so this is also called night vision CCD, but this equipment is very expensive, and many military-grade monitoring equipment are.

And these devices, even their infrared night vision devices, may not be able to detect clearly, so care must be taken.

Lin Rui made a gesture for Sergei to turn on the emI jammer, and then walked downstairs together.
