A squad of soldiers, mercenaries headed by Kuaima, were all resolved within a minute.

Lin Rui led someone into this underground facility. This is an old military underground facility. It was supposed to be used for storage and combat command.

Lin Rui and others did not go deep immediately, but opened an instrument to probe the entire underground facility.

This instrument is an ultrasonic probe, originally used for underground cave surveys. Ultrasonic waves are reflected on the wall of the cave, and the internal structure of the cave is obtained according to the ultrasonic feedback.

This is also the experience of Kuaima when fighting in Afghanistan. When fighting terrorism in Afghanistan, terrorists often dig a large number of underground bunkers. Hidden soldiers and supplies.

With this instrument, the main structure of the underground cave can be quickly surveyed, and a rough map outline can be quickly formed on the mobile computer.

In conjunction with the life detector for search and rescue, it can locate enemy forces in underground facilities. And display the structure diagram of underground facilities.

Most of these are technologies that Yankees have used in anti-terrorism operations. So Kuaima is comfortable with this set. The other several mercenaries set up a communication signal repeater at intervals to maintain communication.

This also provided great convenience to their actions, and the players continued to move forward under the instructions of Kuaima.

The sporadic gunshots faintly heard in front made everyone a little nervous.

At this time, due to the role of the communication repeater. They finally received the wireless signals of the two teams.

"Call Division C and Division D. This is Rick, and we have entered the underground facility. Report your location and current situation." Lin Rui led the people forward vigilantly while pressing the communicator on the helmet to continue calling.

A noisy sound signal came from the communicator. "Is the boss you? The boss... I don't know where we are... It should be a warehouse... Scarface and us are both trapped."

"Sausage, is the sausage you? A **** signal... Hold on, don't move... Tell me about your general situation!" Lin Rui asked while pressing the communicator.

"This is a front-line command post of the enemy army. We killed their command post...but we didn't have time to withdraw." Sausage spoke while gunfire continued.

"That location!" Lin Rui turned around and said to Kuai Ma, "At two o'clock, scan the situation over there."

"There are results, there are a lot of life signals... There are a lot of people. From the map, it is an underground storage facility. Our people should be trapped there." Kuaima looked at the instrument and said in a low voice.

"Let's go, let's go over! Be careful, we are about to face a large number of enemies soon." Lin Rui took up the weapon and walked ahead.

He put on the night vision goggles on the helmet, then walked to the side of the tunnel and checked the cables on the top of the cave. There were many thicker cables distributed on them.

"According to the thickness of the cable, it should be the main cable for this bunker. Someone will blow up the cable and break it." Lin Rui waved his hand.

A mercenary rushed over immediately and placed a plastic bomb on the cable to detonate it. Among Lin Rui's mercenaries, there are many explosive talents. They have considerable research on directional blasting.

Only a small amount of charge was used, but after detonation, multiple main cables were completely broken. It did not cause much damage to the basement.

The entire underground facility plunged into darkness suddenly, relying on night vision equipment, Lin Rui led the people to move on.

The sudden power outage caused panic among the enemy troops, who have not yet adapted. Light in total darkness.

But Lin Rui and others used night vision devices to see everything around them clearly. This is a battle between the discerning man and the blind man.

"Da da da……"

"boom!"

"Papa papa..." The gunfire continued.

Under the lens of the thermal imager, all people have formed contours of gradual color because of the slight difference in temperature of various parts of the body.

The blood ejected under the burst of bullets. It appears orange-red, and then gradually turns into yellow and cyan due to the cold of the blood.

In fact, Lin Rui didn't like it very much and used a thermal imager. This makes him not clear about the specific appearance of his opponent, only a rough outline.

Shooting a target like this will not feel any guilt, just like playing a video game. Everything seems so unreal. It is easy to lose judgment and become addicted to killing. Blindly pursue shooting the enemy.

But if it is under the light, it is a scene of **** full of blood. The blood and the corpse would warn themselves that they could be one of them at any time. This makes people more cautious.

On the battlefield, crazy killing will not make you go further. Only caution can keep you alive.

The secret society militants who were suddenly hit fought hard to resist. They couldn't see the enemy, they could only shoot randomly at the general direction of Lin Rui and the others.

Although the flame arrester can effectively reduce the brightness of the muzzle flame, it will still expose itself in the state of bursts.

Because the muzzle flame suppressor, like the muffler, can't completely eliminate the fire and sound caused by the shooting.

So after shooting for a while, Lin Rui immediately asked the players to spread out and hide. Evacuate at the L-shaped intersection of the underground passage.

"Boss and their firepower is too fierce. I know why Sausage and Scarface are trapped here. There is a company surrounding them." Kuaima leaned against the wall and gasped with his gun. .

"Isn't it better to have a lot of people? You don't need to aim and hold a gun and just sweep it." Lin Rui also joked against the wall, "Well, by the way, the technique you used to kill the guards seemed like It's very special. I haven't seen many people use it. Where did you learn it?"

"You mean the CAR system? This is a wild way, contrary to the US military's standard shooting training system. If you are interested, I will teach you how to use it." Kuaima joked while changing its magazine.

"It's settled. This technique is a bit special. When I have time, I really want to learn how to play with you." Lin Rui quickly pointed out his head and shot, and asked Kuai Ma in a low voice, "Should it be almost time?"

"I think it's almost done. Usually, a minute or two is enough. It's time to surprise them." Quickly nodded.

"It's **** pay attention. They should be used to the surrounding light now, let's give them some surprises." Lin Rui chuckled in the communication channel. "Three, two, one!"

Following Lin Rui's command, multiple hand flashing grenades, cast them at the militants in the secret society.

The mercenaries all squatted against the wall, burying their heads between their legs and arms. The strong light that broke out in an instant caused a burst of exclamation and screams from the secret society militants.
