Chapter 1787: Break the wall

"Received." Lin Rui responded in a low voice. He winked at Sergey, and Sergey nodded and walked forward. About three hundred meters away, there were a few guards guarding them. They couldn't pass at all, but the side passage was unguarded.
Sergey, Lin Rui and the others went to the side passage, but when they got there, a guard called out, "Hey, you guys! Where are you going?"
"There may be something wrong with the wiring there. I will ask two maintenance workers to check it out. Is there any problem?" Sergey turned around.
"What are you holding in your hand?" The guard walked over a few steps and frowned as he looked at what was in Lin Rui's hand. "The use of electronic devices is prohibited here."
"What's up, buddy? How can you use a multimeter to check the wiring? Does the equipment have electricity, and where is the wiring faulty, should we touch it with our hands? If this is also an electronic device, then our modern shipyard, simply It's good to return to the handicraft workshop." Sergey complained.
The guard stretched out his hand and said, "Can I take a look?"
Lin Rui could only hand him the tablet computer disguised as a multimeter. The guard took a look and frowned, "What is the LCD screen behind?"
"Electronic drawings are used directly to display circuit diagrams. Many facilities in this place are from the last century, so the maintenance work is very heavy. And you know how big it is, we can't run around with bundles of drawings." Lin Rui Reaching out and clicking on the tablet, a complicated circuit diagram was displayed on it.
The guard was relieved. But he nodded and looked at Lin Rui, "You are..."
"He is a Tuva, but his electrical skills are not bad. Can we go? I would be very happy to be with you. It's best to drink coffee and blow the cow all morning. But we really have a big There is a lot of work to do." Sergey shrugged.
"Oh, of course. You can go now." The guard looked at the card on their chest and nodded. Tuva people are one of the few yellow people in the Russian Federation. Lin Rui's face and height fit Sergei's description very well. The guard couldn't fault it, so he could only wave and let them go.
They pretended to be calm, and took a breath after they had completely walked into the side passage.
"It was too dangerous just now." Sergey shook his head. "But boss, I really convinced you that I dare to show him the tablet. If he finds out, we will be all over."
"The more you are at this time, the less you can be nervous. If I showed a little uneasy emotion just now, he would be suspicious, so the more calm he is, the less sure he is. Besides, industrial-grade tablets and military tablets There is no obvious difference between them. But if he really intends to check it carefully, I can't do anything about it. Fortunately, I bet it right." Lin Rui also whispered.
"It's a gambling, it's a life-threatening! I'm ready to do it. If he asked me in Russian just now, there would be really no way." Lincoln smiled bitterly.
A few workers from the Severodvinsk shipyard came across, and the three of them walked past them with their heads down. Fortunately, those workers did not notice them either.
"Be careful, there is camera monitoring in front." Lincoln scanned the tactical tablet in his hand, and the fill light of the surveillance camera was clearly displayed on his tablet.
"I saw it." Sergey whispered, "Follow me and walk against the wall. If you meet someone, pretend to check the circuit." He walked forward against the wall to avoid surveillance equipment overhead.
At present, except for a few multi-camera monitoring devices that can achieve 360-degree monitoring without blind spots, almost all traditional monitoring camera devices are set to be slightly inclined from top to bottom in order to obtain the maximum observation range. This will leave a certain blind spot for observation. Especially below the camera monitoring, there is an absolute blind spot.
Sergey is an expert on how to avoid this kind of camera surveillance. Lin Rui and others followed him through this area under very safe conditions and went directly to the already closed passage.
There is no light here, it looks very dark. Lin Rui waited more than three minutes to adjust his eyes to the light. "That's it," Sergey whispered, "Behind this wall, there should be the warehouse that was partitioned off."
"What are you waiting for, let's start!" Lin Rui whispered, "Sergey, be smarter, go to the back and let us know if someone approaches."
"It's so hidden here, under normal circumstances, no one will come." Sergey whispered, "Is it necessary to go outside to watch? I stay and can help."
"It's hidden here, but it's also very quiet. If we hit the wall, we will definitely make a sound. I don't want to be discovered because of this." Lin Rui whispered, "You are watching outside, if someone approaches, Remind us to stop immediately. We will do it again when someone is over, you know?"
"It's really embarrassing, we are actually reduced to the point where we use a hammer to smash the wall. If the sausage is there, let him blow it out with C4, it will be more enjoyable." Sergey muttered.
"Unless you don't want to live at all, and our aim is not only to sneak into this place, but to help Cobain invade the system here silently." Lin Rui whispered, "This is not a time for fun. It's work, understand? Go out and stare!"
"Well, you are the boss." Sergey turned and walked outside to watch.
Lin Rui and Lincoln began to break the wall. There are hammers and chisels hidden in their tool bags. Although this kind of small hammer hits the wall as fast as a sledgehammer, it is fine and small, and the sound and vibrations are not too great.
Punching holes in the wall is also a technical task. First of all, you can't hit hard in the middle, because this will make a lot of vibrations and sounds, just like drumming. Anyone who has beaten drums knows that the sound of drumsticks hitting the middle of the drum is particularly loud, but the farther to the edge, the lower the sound. This is related to the vibration of the drum, the more violent the vibration, the stronger the occurrence.
The same is true for smashing a wall, because the other side is also a space, so smashing it in the middle will cause a lot of vibration and cause reverberation. The sound of "dong dong" will be obvious.
So the correct way is to start near the bottom edge of the foundation, so that the vibration of the hammer will be transmitted to the foundation of the wall more quickly, and there will be no echo vibration. Lin Rui and Lincoln squatted down and quickly leaned under the wall, pulling out a hole large enough to bend over to go through.
