It is not known who built the tunnel, which is just over a meter wide, but it is said that there is a similar tunnel in Iraq, which was used by resistance groups to hide against the US-led multinational force.

Long Yun smelled the smell of corruption, obviously this tunnel is not used very often, it seems that Haynes's intelligence work is very good, and it is estimated that the detailed construction plan of Fort Irwin is also on his hands. However, in the case of a secret organization with a strong background like the Restoration Society, if needed, they can get architectural drawings of any part of the world.

Long Yun cautiously climbed down the stairs, in this kind of dark place, although he wore a 120-degree wide-angle night vision device, but after all, it was only a night vision device, if the opponent was an experienced special forces soldier, all kinds of traps could be laid in any place here, the simplest is to use two American military-style broadsword mines, and use a metal wire not much bigger than a hair to link it at the important entrance and exit, if you accidentally trip, there is almost no possibility of survival.

Each broadsword mine is loaded with at least 700 steel balls, and the explosion damage range includes 50 meters in front of it, spreading in a 60-degree wide angle in a fan-shaped range; The height is 2 to 2.4 meters, and the maximum range of the steel ball can even reach 250 meters, including a moderate kill range of about 100 meters.

This lethality can only be described as terrifying, if there is no cover, two broadsword mines can knock down a platoon of soldiers in an instant.

Long Yun has seen unlucky people killed by broadsword mines in Africa. It was a ****** mercenary who triggered a broadsword mine in the jungle, only one of the five accomplices survived, and the rest were torn into a puddle of rotten flesh by the steel balls.

Sure enough, Long Yun's caution brought a reward. As we were about to finish the stairs, there was a reflection on the ground about 40 centimeters that was difficult to notice.

"Stop!" Long Yun raised his fist and made a gesture to stop advancing, Gege squatted down lightly, and asked in a low voice through the laryngeal shock headphones, "What's wrong?" ”

"Booby." Long Yun lightly put his hand on the glimmer of light, and found that it was indeed a metal wire.

Hum! Long Yun said secretly, although this bait mine is very standard, because people rarely lift their feet more than forty centimeters when walking, and the tripwire is too high and will be reflected in the target's line of sight, it is easy to be exposed, and forty centimeters is just right.

Slowly touching along the tightrope, Long Yun found a broadsword mine in a hidden position in the corner, this is the training base of the US military, this kind of mine is really at his fingertips.

Long Yun retracted his hand and said softly, "There is a tripwire here, I'm going to cut it." ”

He took out a Leeseman EOD bomb dispersal pliers from his shoulder bag, gently stretched it out to the steel wire, and first tested the pressure of the test line with his hands, if the other party was using an elastic steel wire cable, Long Yun had to grab the other end of the steel cable with one hand, otherwise he would cut the tripwire, and the other end would bounce back, and the force was enough to tear off the safety bolt on the other broadsword mine.

Fortunately, Long Yun quickly discovered that this was not an elastic steel cable, and it seemed that the guy who arranged the booby didn't set up too many problems.

After cutting it, the broadsword mine was eliminated, and Long Yun breathed a sigh of relief.

Gege glanced at Long Yun, raised his wrist, signaled that time was pressing, and he was about to go down when he stood up.

Long Yun stayed where he was and didn't move, and suddenly grabbed Gege.

Gege was startled and said in a low annoyance: "What are you doing?" ”

Long Yun looked down and saw that he didn't pay attention to the place where he started in the dark, and he actually pulled Gege's chest clothes directly, although he was through the thick body armor, he could still feel the elasticity.

"I'm sorry, I'm sorry." Long Yun hurriedly apologized, his old face flushed, and said, "It's too simple." ”

"What?!" Gege didn't understand it all of a sudden, and felt that this guy was simply wasting time, and if he delayed it like this, Haines would have already gone away and flew high, and what else was he chasing.

"I said—it's too simple." Long Yun said word by word: "They are not so stupid!" ”

"What the hell are you talking about?" Gege still didn't understand, thinking that Long Yun was playing tricks, and even thought that this guy was taking the opportunity to rub oil.

Long Yun didn't want to explain here, he cautiously looked around, in front of him was the end of the tunnel steps, and below was obviously a relatively spacious room, and no one knew what was inside.

"Let's go back."

"Go back!?" Gege was surprised, thinking to himself what kind of plane this guy was doing, and he would go back at this time? She thought that Long Yun was too cautious, perhaps because she was afraid that she would be ambushed as soon as she left the tunnel, so she didn't dare to move on.

What a coward! Gege cursed in his heart, in fact, he walked to the entrance of the tunnel, and then turned the corner and there was still a smoke bomb or shock bomb inside, and he could just take the opportunity to rush in. This kind of simple tactical cooperation, no matter which training school will teach, Long Yun is an elite mercenary who has been mixed in Africa for several years, how can he not even understand this.

However, she doesn't want to have a dispute here, now she and Long Yun are going deep into the enemy's nest, which can be regarded as serious partners, and they must take into account the overall situation, otherwise they will be finished.

Retreating to the corner of the stairs above, Long Yun crouched down and looked for something on the ground.

"What the hell are you going to do!" Gege couldn't help it anymore and asked in a low voice.

Long Yun didn't pay attention to her, but lowered his head and continued to look for her, and stood up after more than ten seconds, with a few more stones in his hand.

Looking for stones!? What the hell is this guy going to do! Gege felt that he was really going to be angry, and if he wasn't in the enemy's lair now, he would have just frozen him into a popsicle right now.

Long Yun picked up one of the stones and threw it towards the end of the steps.

Poof-

The stone slammed into the dirt with a dull thud and rolled out a few meters away.

After a pause, Long Yun picked up another stone, repeated the previous action, and smashed it.

Poof-

The stone continued to roll out for a long distance, but there was still no response.

"Are you crazy?!" Gege stomped his feet in anger and gestured wildly, reminding Long Yun that now was not the time to throw stones.

Long Yun raised his index finger and made a silent movement, and said softly: "I'll let you rush at you later." ”

Anyway, a stone was thrown.

Still no movement.

"What the hell are you going to do? Do you want to throw stones to lure them out? Gege almost gritted his teeth.

Long Yun obviously didn't expect that his stone still didn't achieve the expected effect, and he frowned, he still had the last largest stone left in his hand.

After weighing the weight in his hand, Long Yun smashed it out again, different from the previous times, and the landing point was different.

This time, there was a reaction, but the reaction was a little bigger.

Boom –

There was a violent explosion at the end of the steps, and the stone obviously hit some explosives, and the air waves rolled up the thick loess, and the whole tunnel was dusty and blurry.

Almost at the same time, several explosions occurred one after another, and the broadsword mines that had been cleared by Long Yun were detonated together because they were too close to the explosion point, and more than 1,400 steel balls flew in all directions, smashing the surrounding walls with a sneer.

Accompanied by the explosion, several screams were heard at the same time, and the people who were apparently hiding below were affected by the broadsword mines and explosives, and were injured.

"Follow me!" As soon as the explosion stopped, Long Yun had already rushed down the steps of the tunnel with his gun in his hand like a cheetah.
