Battlefield Contractor

After entering the corridor below, there is a corridor. It's relatively safer here, but Lin Rui still found through a sight glass inspection that there were two guards in the corridor ahead.

He retracted the sight glass and signed orders to the players.

Sergey nodded, turned and walked ahead. The two guards were at the door of a room and didn't seem to be surprised when they walked in. Just looking at them, one of them said, "How is the situation outside?"

"I have to stay up all night anyway," Sergey whispered. While he was talking, he continued to walk forward, and Lin Rui followed him. The two guards chuckled in a low voice, and took the cigarettes out of their pockets to smoke together. It seems that I just came here to smoke.

Lin Rui took two steps and walked forward side by side with Sergey. Then Lin Rui cast a wink at Sergey, and then moved suddenly. Lin Rui's arms were wrong, and he locked one of the guards' necks with his arms and twisted it hard. The guard broke his neck with both arms on the spot.

And Sergey also strangled the neck of the other guard and shot an anesthesia gun in his neck. The guard stopped moving after only a few struggles. The biscuit behind him waited for a few o2 team members, and quickly came over and dragged the two guards outside.

Lin Rui leaned against the door and listened, and said in a low voice, "There is a voice here, it should be the duty monitoring room. Remember, don't make too much noise after you enter, and clear the people inside."

"Boss, we are going to catch Adric. There is no need to get into this trouble, right?" Sausage whispered.

"What do you know? This surveillance room can provide us with more accurate information. Otherwise, you know where Adric is hiding and how to find him?" Sergey said, "Besides controlling the surveillance room, you can use the camera Monitoring and viewing the entire area is of great significance to us."

"Okay." Sausage nodded.

Lin Rui stretched out three fingers, then began to count down silently. Put down the last finger. Lin Rui and Sergey pushed the door and walked in. The people inside found no abnormalities for a while, and they opened fire continuously. Even worse, none of these duty room personnel have weapons in their hands. At this time, they were all knocked down by surprise.

"Jian An!" Lin Rui pointed to the surveillance video, nodded his head, and connected his tactical tablet to the computer in the duty room. Soon he completed the investigation of the surveillance video area. Whisper. "We are currently in the North District. Where is this Edric is not clearly marked. But from their surveillance video, the lower part of the South District is the most likely."

"There is a lower level here?" Gunsling frowned.

"Yes, but we have to go to the Southern District to talk." Jiang An said in a low voice, "Moreover, there must be at least two people left here."

Lin Rui nodded and said, "Guns, roses, you two will stay. The others will follow me and guide us through surveillance video at any time."

"Understand." Rose nodded, "I'll leave it to us."

Lin Rui looked at his watch and said in a low voice, "There is not much time, we have to hurry up."

They turned and continued through the corridor, turning to the south, where there was no staircase but an elevator. Lin Rui and others walked in and checked, and then whispered, "This should be an elevator, but it seems that there is no switch."

"That should be remote control. Take a good look at the guns. There should be a remote control button next to the monitoring device." Sergey checked and gestured to the camera.

The guns and Rose staying in the duty room all nodded, "We are looking for it. If it is remotely controlled, then the switch should be in the duty room. Okay, I found it." Guns found the elevator next to the monitoring computer in the duty room. Button. After pressing, the slight tremor that the elevator started to produce finally began to descend.

"The defense of this place is really strict. They designed it this way. Even if someone sneaks in, they still can't enter the next floor without the permission of the guard on duty." Lin Rui whispered.

"Indeed." Jiang An whispered.

"I wonder if we will face a large number of enemy troops after we go down. If this is the case, we would be bad. Because we can't make any mistakes." Sergey whispered.

"You go ahead." Lin Rui nodded. "Beware of traps."

They took the elevator to the lower level. Sergey walked ahead with a gun, and they found another door. There seemed to be no guards here, but Sergey stopped when he was about to move forward. He checked his feet, where there was a thick carpet. He immediately reached out to stop the others from moving forward.

"What's the matter?" Jiang An whispered.

"It's not quite right. This kind of carpet is very thick and elegant. If it is spread in the room, it is normal. But there is also such a carpet in the aisle, but it is not quite right." Sergey squatted down and stuck a dagger in it. On the carpet. The sharp dagger quickly cut the carpet, and he reached out his hand and touched it in a low voice. "Sure enough, there is a ghost."

"What's the matter?" Lin Rui frowned.

"A leaky cable induction alarm device. The system consists of a detector host and two leaky cables specially processed according to design requirements. The detector host is composed of a power supply unit, a transmitting power supply, a receiving power supply, a signal processing unit and a detection unit.

The host used in a low temperature environment is equipped with a combined thermostat unit. The leaky cable as the detection unit consists of two leaky cables and two non-leaky cables connected to them. Each non-leakage cable has a nominal length of 10 meters, and each leaky cable has a larger nominal length.

The transmitting unit generates high-frequency energy and feeds it into the leaky cable for transmission and transmits it in the cable. When energy is transmitted along the cable, part of the energy leaks into the space through the leaky cable, and an electromagnetic field is established in the guarded space. Part of the energy is received by the leaky cable installed nearby to form a direct coupling between receiving and sending energy.

When an intruder enters the induction zone formed by the two cables, this part of the electromagnetic energy is disturbed, causing a change in the received signal. This changed signal is detected after being amplified, and the alarm indicator is pushed to light up and the relay The contact opens. Sergey whispered.

"Damn, I already knew that things wouldn't be that simple." Lin Rui whispered. The guards outside were tight, but there was no one here, which was strange at first. Russ, how about it, can you dismantle it? "

"No problem. The person who deployed this alarm device was better than anyone expected. It does not mean how difficult the system itself is." Sergey whispered, "Give me a few minutes."
