Everyone's actions were very timely, from getting rid of the guards, to changing to posing as security guards. They only took a few minutes.

In the security office, apart from the surveillance video flashing for a few seconds, there was not much abnormality. Although it seemed to the surveillance office that the security personnel in charge of this area had been away from the surveillance video for a few minutes, they soon returned and sat down.

This is not too unusual for them. No matter how good the security personnel are, it is impossible to sit there for a long time. After sitting for a period of time, it is normal to stand up and move around and take a look around.

Therefore, their actions were not discovered by the monitoring personnel of the Security Office.

After finishing all this, Lin Rui also breathed a sigh of relief, and turned his head and exchanged glances with Russian Sergey. Now they only had two other guards left, and an electronic door lock needed to be solved.

Fortunately, the other two guards are not in the surveillance area. Their location is on the side.

"Quick horse, sausage, hand it to you." Lin Rui gestured to them.

The sausages were almost standing close to the corner, because judging from the sound of footsteps, the two guards were moving. When they walked to Sausage and Kuaima, the two quickly stepped out.

The sharp dagger in his hand slammed into the two guards. One of the guards caught off guard and was stabbed by the quick horse.

But the other security guard had better luck. His MP5 submachine gun hung on his chest, helping him block the knife.

The security guard saw the dagger stuck on his chest and reacted suddenly. When he was about to shout, his head was suddenly pulled 180 degrees by a pair of powerful hands. The whole person petrified in an instant, and then fell unwillingly.

Kuai Ma stood behind him and silently supported the security guard to prevent him from falling to the ground.

At the critical moment, this new player, who has been taciturn, avoided a teammate's mistake.

In fact, if the security guard yells, or warns with a wireless communicator. All of them will be exposed instantly.

It can be said that Liszt quickly saved this action. Lin Rui patted him on the shoulder, "Good job, keep moving."

Quickly nodded, dragged the body of the security guard to a hidden place and hid it.

After finishing all this, Lin Rui and the others continued to move forward, and they stopped at the end of the corridor.

Because Lin Rui made a stop gesture. In front is a heavy fully enclosed metal door, which should be an electronic door lock.

And above the door, is a surveillance camera.

"How to solve it?" Lin Rui looked at Sergei in a low voice.

"The surveillance device can be used for hands and feet. I need to shoot a video at the same angle, and then place it in front of the surveillance video and play it in a loop." Sergey turned his head and said, holding the tactical tablet and small speculum in his hand, "I need at least five Minutes."

Lin Rui nodded and asked the other team members to guard the surroundings while Sergey acted. Although the two most important groups of guards on this floor have been solved by them, they still have to be just in case.

Sergey first recorded a video with a small speculum, then set it to loop on the tactical flat panel, and then put the flat panel in front of the surveillance video.

In this way, the images recorded by the surveillance video are all scenes played on the tactical panel.

This principle may seem simple, but it actually requires quite detailed operation. First of all, the shooting angle of the small speculum must be exactly the same as the surveillance video to make the captured image consistent with the surveillance video.

Otherwise, different shooting angles will cause different pictures. For the guard who has been staring at this surveillance video for a long time. It is easy to find the problem.

In addition, he must place the tactical tablet in a very suitable position to completely cover the surveillance video and make the surveillance video appear to be working properly.

The whole process, Sergey used five or six minutes, but he finally completed it perfectly. After all, for a rich old thief like him, he has the means to deal with such surveillance video.

"Done." Sergey snapped his fingers. "The only thing left is this door."

Scarface looked at the tactical tablet placed in front of the surveillance video and shook his head in disbelief, "Russian, you're such a **** genius as a thief."

"Thanks to the praise, but what a thief needs is not talent, but long-term hard training. As well as being beaten to death, and often in jail, the experience and training." Sergey shook his head, "No one is born. Be a thief, I was just forced out.

If I was born into a senior society, my parents would have both. Maybe I will also go to university and have a decent career. But it's a pity that I am an orphan. The so-called talent is just a means of making a living. "

Sergey walked to the door, put on his gloves, and examined the door carefully.

"This is a German product. Like all Germans, it is rigorous and meticulous. It uses multiple anti-theft and anti-dismantling devices. This is the top security door that has only recently become popular on the market.

It uses iris and fingerprint recognition, and also requires a key card that cannot be copied to unlock it. The thickness of this door is likely to be one foot or even two feet thick. "Sergey took out an instrument and put it on the door, and checked it.

After looking at the inspection results, Sergey turned his head and said, "The surrounding frame is a reflection, even if you take a rocket launcher, it may not be able to explode."

"Just say, can you unlock it?" Lin Rui whispered.

"I have never seen a door of this type. I need to try it." Sergey said seriously.

"Then hurry up, we don't have to spend much time here. If you can do something, act quickly." Lin Rui nodded.

Sergey squatted down, "Generally all electronic door locks have a maintenance port. To provide a solution after a failure is completely locked. So in theory, most electronic door locks can be removed. Solution.

But this door uses a new type of anti-dismantling technology, and the maintenance port below requires a special decoding card to unlock it.

In other words, their service port itself is an anti-theft lock, which is very difficult to disassemble mechanically. So it will take some time. Sergey whispered.

"What are you doing?" Potato Chips couldn't help asking.

"Test the thickness of the locking device of the service port to evaluate the possibility of violent disassembly." Sergey replied in a low voice while looking at his instrument.
