Chapter 3391: Suojiang Deep Valley

Time passed a little bit, and the night fell. Just as Lin Rui had predicted, in this gully area, it appeared to be darker than normal natural light.
"Everyone pays attention, do a final check, and then we are ready to act." Lin Rui whispered, "This operation takes silent and covert operations as the primary consideration. If you don't have a last resort, you can't expose yourself. Crazy Horse and Scimitar Lead the team, the others follow."
Crazy Horse and Scimitar had explored the route in advance during the day. So the two of them were familiar with the road and took other mercenaries from one side of the valley to the southwest. This terrain is a gully area washed out by an ancient river course. The location near the southwest is the lowest, which results in a large height difference between the ground and the bottom of the valley. It belongs to the place with the largest height difference in this area, and it has appeared before. The collapse of the scale.
Crazy Horse's plan is to sneak in from here. Since this place has collapsed in the past, the secret society militants camp below must be avoided here, in a far away position. Because the formed after the collapse is not very strong, it is easy to cause a situation similar to a landslide. So sneaking from here is safer than other locations.
Crazy Horse leaned over on the ground and climbed for a while with a low-posture motion, beckoning Lin Rui and others to follow. Lin Rui crawled to him, Crazy Horse pointed down with his finger, and said in a low voice, "Did you see there?"
Lin Rui looked over with a telescope and found a few faint rays of light. "Is that there?" Lin Rui whispered.
"That's it. It was originally at the bottom of the valley, but these secret society members used engineering machinery to dig a section along the valley wall, forming a side cave entrance. The entrance to the illegal mine should be there, because it is quite hidden. , Even aerial reconnaissance may not be able to find anomalies." Crazy Horse nodded. "The light comes out from the inside, and the periphery must be controlled at night. So it's so dark that nothing can be seen.
"The guard whistle is there." Sausage whispered while holding the night vision goggles. "There is another one there, at least one kilometer away from our side. They may not be able to accurately spot us at this distance. Especially our side, which is actually backlit. The side."
"What if they have night vision?" Sergey whispered.
"It's okay. I have calculated that the night vision device cannot accurately identify us at this distance. The observation distance of the night vision device is the same as the fuel consumption of the car. The environmental impact is very large. Many of the data given by the manufacturer is a theory. Value. The observation distance of the night vision device is severely affected by the darkness and the weather quality such as fog and rain.
At the same time, the sensing distance of the night vision device is divided into low-light observation distance and total black observation distance. The total black observation distance needs the auxiliary light source of the infrared transmitter to cooperate, so it will be affected by the distance of the infrared transmitter. Generally, the night vision device of the 1st generation or 1st generation+ has a low-light observation distance of 50-100 meters. The second and third-generation night vision devices have a distance of about 100-400 meters. If you want to see 800 meters away, at least the fifth-generation night vision device that is still in the experimental stage, even the wealthy US military cannot currently deploy it. That's why I said this is a safe drop-off point. "The Crazy Horse replied.
"Okay, get ready to lower the rope. Crazy Horse and Scimitar go down first, let's keep up. After going down, don't blindly rush, watch on the spot, find out the surrounding environment before acting." Lin Rui whispered.
"Understood." The players agreed.
Three rope drop nylon ropes are fixed on a relatively strong rock. The players descended down the nylon rope used for rappelling.
Because of the mercenaries of the Black Island Company, helicopters are often needed to perform tasks. So descending is a must-have skill for each of them.
Cable landing is different from plane landing. It is a combat method in which the helicopters hover in the air and the soldiers rappelling to the ground.
Because cable descent has low terrain requirements, it is suitable for responding to emergencies. It only takes a few seconds to descend a soldier. When several ropes are used at the same time, the soldiers of the army can all be put into battle in the battlefield in just ten seconds.
Seizing the time to surrender on the battlefield can prevent our soldiers from being discovered by the enemy. To better cooperate with regular troops, the hovering helicopter can also maintain alertness, and the airborne heavy machine gun can detect the enemy and shoot at the target. Therefore, in the face of a battlefield where there may be an ambush, it is safest to take a descent.
The cable descending on the mountain wall is supported by the mountain wall on one side. In theory, it is more stable and faster than a helicopter cable landing.
It didn't take long for these O2 squad mercenaries to descend to the bottom of the valley. The mercenaries who landed first have reached the bottom and have begun to scatter on alert. Lin Rui and a few other mercenaries were the last batch of ropes to drop to the bottom.
"Report the surrounding situation." Lin Rui asked in a low voice through the wireless headset.
"Safe on the left." Scimitar whispered.
"The right side is safe." Scarface's voice.
"The road ahead has not been ascertained, and there are no signs of enemy troops within 200 meters. It is safe." Crazy Horse replied.
Lin Rui nodded and said, "Close the formation. Continue to advance towards the target. Pay attention to the surrounding environment. There may be a dark whistle or mine nearby."
"Understand." Crazy Horse responded, and then led the team to move on.
"Stop." The sausage walking in front suddenly made a gesture of raising a fist.
This was a sign language for the whole team to stop advancing. The whole team stopped. The team members all held guns and watched their surroundings vigilantly.
"What's the situation?" Lin Rui asked in a low voice.
"The road here is a bit weird," Sausage whispered, "I'm afraid you really said it. This should be a minefield."
"I have known for a long time that they can't be defenseless in such obvious places." Crazy Horse whispered. "How did you find a minefield?"
"Generally, all minefields are set up with warning signs in order to prevent their own personnel from accidentally touching them." Sausage said decisively, "Look over there, there are two trees. It should be impossible for this kind of valley to grow these two trees alone. . But no grass grows in other places."
"Unless, other places have been cleaned up as a whole. The purpose of cleaning up this place is to obtain a relatively smooth road.
Such pavements are usually used for mechanical mining. This relatively flat area should be a minefield. Two trees were left alone over there, which were used as signs of minefields. "Sausage replied affirmatively.
"You mean, such a large area here may be minefields?" Sergey whispered.
"It may not be so exaggerated, but if it is a mechanical mine, it means that they mine a lot. It may be a medium-scale or even a large-scale minefield. In this case, the depth of this minefield may exceed 400 meters." Whisper.
