It takes more than courage to go from light to darkness. Although all three of them held hernia spotlights, which could penetrate the darkness from a hundred meters away, it was still a drop in the bucket for this bottomless mine.

Bullet casings and protective gear were scattered everywhere on the torn floor, and the corpses and blood were gone, making it feel like a demon had swept the battlefield.

The cave was not as wide as it was, the size of a truck to pass through, and the walls of the cave were supported by metal supports, leaving sharp rocks exposed everywhere.

The air in the mine is no longer fresh, and no amount of fresh air system can make this 9 kilometers above the surface as fresh as the air outside.

The smell of muck and kerosene is mixed with disgusting.

On the ground, the signal received by the on-call team members was no longer stable, and even the picture seen by Kunsha 07 was interrupted from time to time and turned into snowflakes.

"Stop!" Suddenly, the advancing nightingale signaled.

"What's wrong? Found something? Brother Xin mobilized the sensors to scan all kinds of advances, but found nothing.

"There's something up ahead." The nightingale said as she drew the bowstring, and the pitch-black arrow feathers set up the bow of the day-to-day battle.

"What's that?" Zhang Lan couldn't see anything.

"I don't know, but it's dangerous, very dangerous." The nightingale relied entirely on the hunter's instincts to aim, and with a deep breath, the arrow feathers flew straight out.

After flying out of 200 meters, the extremely light nano arrow feather accelerated to break through the sound barrier, and the arrow flew straight like a cannonball, like a bamboo, but it stopped at 600 meters when it hit something with a "dang" sound.

It wasn't the sound of a rock wall, it wasn't the sound of metal, and everyone saw that in the dark cavern in front of them, a pair of green compound eyes like light bulbs suddenly lit up, and they rushed forward with a roar.

"Fire!" Zhang Lan raised his gun and shot continuously, and Brother Xin also carried a machine gun and fired at full power.

For a moment, the firelight illuminated the rock walls around everyone, and also illuminated the monsters rushing in front of them. That's a bunch of ...... Ant?!

They were the size of a domestic dog, and their huge jaws and fangs felt like they could even pinch through the steel bars, and gravity was completely unrepresentable along the walls of the crater.

The most important thing is that the shell of this group of red ants is extremely hard, and Zhang Lan's bullets will be ejected if they hit it at the wrong angle.

You must know that he uses a special armor-piercing warhead, which can even make a hole in the side armor of ordinary armored vehicles, but it has no great effect on these ants, and only by hitting the compound eye can they blow their heads, otherwise the attack effect will be halved.

"Retreat! I can't finish fighting! The nightingale drew an arrow from the arrow niche behind her, flashing a blue metallic feather, and shot it with a bow.

The aimless arrow feathers flew through the center of the ants on the four walls, and then instantly split and began to catapult indiscriminately, and the split arrows jumped back and forth hundreds of times, and thousands of Guanghua wiped out a dozen ants in an instant.

"Run!" Zhang Lan casually dropped a few marble-like mines, pulled everyone to turn around and leave quickly.

The chasing ants didn't care about any resistance, they continued to charge forward like brainless machines, and the moment their six feet stepped on the marble bomb, there was a loud bang, and the fire illuminated the entire mine, and also activated the demons that inhabited the entire mine.

Back? Without. The ants crawling out of the other mines quickly blocked the mine junction where they came, and the sound of sizzling echoed through the dark mine.

In a dilemma, Zhang Lan looked at the mine branch on the side, "Go here." ”

"You're kidding! After leaving the main mine, it's like a labyrinth below, and you can't find your way back! Brother Xin strafed the ant colony that attacked from the opposite side.

"Stay here, 1% survival rate, walk in, 5.8% survival rate, guess I'm kidding?" Zhang Lan took the lead and walked into the branch mine.

The branch mine became narrower, and the nightingale took out the laser net lock that she had with her, and arranged it on the four walls of the cave behind her, and the red light illuminated the surroundings.

The ants that rushed in front didn't have time to stop, they hit it directly, and the sturdy shell couldn't withstand the laser cutting, and was immediately scattered to the ground.

Boom, the ants exchanged ears, and the speed of information transmission was almost catching up with the radio, and they all quickly stopped.

Through the laser net, Zhang Lan and the three of them made eye contact with the monsters in this kind of mine for the first time, and their whole bodies were red, like sparks that have not been extinguished, flashing with a dark halo.

These ants tilted their heads and looked at Zhang Lan and the others behind the net, their faces expressionless, and they didn't know what they were thinking.

"Flame Army Ant, we have encountered something unavoidable...... Zhang Lan picked up a piece of ant head on the ground that was still smoking, looked at it carefully, and the memory bank in his mind was turned up, "This kind of ant is supposed to live in the desert area, one of the most terrifying S-class wilderness beasts, a colony of at least 1,000 to 20,000 ants can be gathered in a nest, they are omnivorous, eating everything they see that moves." In their range of activity, hardly any other organism can survive. ”

"Holy! Why is this stuff in the Morro mine? "Brother Xin has a melancholy feeling of being drowned in dry land.

"Fifty kilometers further forward from the Morro mine is bordered by desert areas, but it is impossible for such a large swarm of flaming army ants to migrate without being detected by patrolmen." The nightingale frowned.

"Let's go, all we've seen are the most prevalent worker ants in this colony, and records of them are very limited, and who knows what other subvariants?" Zhang Lan took a piece of the ant and put it in his bag, which was the most useful evidence to search.

The three of them got up and ran deeper into the branch mine, throwing behind them the laser net and a swarm of ants that tilted their heads to look at them.

"Now I know why he has killed so many people, he is surrounded by that kind of thing, and he has to run away to be ghostly!" Brother Xin really regretted following into this mine.

"Can you talk less and save the oxygen in the mine?" Nightingale said with disdain.

"The area we are in is the 7th fork of the 13th branch of the underground mine, like 2 kilometers to the east, there will be a place adjacent to the 8th fork of the 16th branch, the distance of the middle rock wall is only 3 meters, we can open it with our equipment, and the 16th branch has a fast rescue channel, which can go straight to the mine surface." Zhang Lan said calmly.

"How do you know that?" Brother Xin mobilized the database in the heavy armor, and there was no such detailed topographic map.

"I memorized the road map here a long time ago before I came, did you just rely on luck for me to survive to this day?" Zhang Lan took the lead and ran forward.
