"It's only 600 bottle caps, damn it, when did the black-backed ant carapace become so worthless, and it was cut off at half the price", Shu Hu whispered outside the supply station, the 6 black-backed ant carapaces were sold for 100 caps each, which was only half the price of the No. 12 mine hall.

"The price of bullets and supplies has also doubled, I happened to meet an acquaintance, it is said that most of the supplies were taken down to the 12-E cave, it seems that there is a large-scale battle there, and all kinds of material support are urgently needed", Pan Lao cringed a little in his eyes, could it be that a new passage between other mines has been opened, and every time this kind of passage appears, fierce battles will break out between the two mercenary teams.

"Massive? What's underneath? Lin Ze refilled the spare 4 point 45 magazines on his body, and he now has a total of 5 magazines with a total of 75 rounds, of which 15 are steel-core armor-piercing bullets obtained from Crazy Luli.

"Cave E is nothing, it is an outpost of prisoners, much larger than here, and the exchange price is darker, but there is an underground water source there, and the team that wants to stay underground for a long time can only go there to replenish, the danger is not the E cave itself, it is sandwiched between the 20 and 21 mining areas, relatively closed, and there are no other exits, and the 19 to 24 mining areas are all new mining areas that have not been developed for a long time in recent years, the resources are the richest, and the more mutant insect swarms, the most troublesome is the F cave after the 24 mining area, It is a natural huge underground cave group, no one knows whether the depths lead to an unknown hell, the prisoner mercenary team has organized manpower exploration, can only barely explore a corner of the F cave, according to known information, the F cave is connected to the No. 1, No. 2, No. 4, No. 9, No. 13 mines, because it is too big, other mines may also be connected, but I don't know where the connection is located, no mercenary team can fully explore the F cave, It is estimated that the firefight below is to encounter a new mine road to collude with other mines or underground creatures that have escaped from the F cave", Pan Lao lame patiently explained, as long as the information about the F cave is basically known to the old mercenaries in the abandoned mine town, it has formed a dark and deep underground world, God knows what will run out of it.

"Let's go, let's go, maybe we can have some harvest in a few mining areas after the 18th."

……

The fortress made of metal concrete in the E cave is divided into two layers, and the searchlights on the defense wall patrol back and forth, providing a field of vision for the heavy fire of the machine gun tower on the guard tower, in addition to the guard tower, there are more than ten infrared positioning automatic rotating machine gun batteries on the top of the defense wall, and in the concrete barracks on the inner layer of the fortress, a group of heavily armed criminal prisoner mercenaries are meeting in the conference room, "Sister Dao, this is the case, we don't know who the attacker is at all, and now we don't dare to send a team to the No. 23 mine area to investigate." ”

"Do you have any clues from the attackers, we lost 6 core members, didn't we find anything at all?" The knife face has a serious expression, the two major mining areas of 23 and 24 are the two most abundant and precious places under the No. 12 mine, if they have been occupied by inexplicable attackers, it will affect the income of the entire criminal mercenary team, and then affect the strength of the mercenary team, not to mention, those attackers seem to be attacking along the mining area, "Could it be people from other mines who came around from the F cave?" ”

"It's impossible Sister Dao, according to the two peripheral mercenaries who were lucky enough to survive, the attacker from the darkness seems to be a snake, and suddenly it catapulted out of the shadow on the side, quickly wrapped around the mercenary, and then quickly dragged back into the shadow outside the range of the light crystal tube, it is impossible to prevent it, and the terrain in the F cave is complicated, the nearest exit of the No. 13 mine from us, if they want to come over, they must pass through two large insect nests, it is impossible to sneak around, and the attacker should be a strange underground creature."

"Underground life...... Shrink the power first", the knife face fell into deep thought, to deal with the underground creatures, you must first figure out what it is, how many there are, and what the strength is, otherwise everything is empty talk and troublesome......

……

"Bang!"

The dust was splashing on the ground, and Lin Ze and his party stopped and looked fixedly at the few mercenaries who were shooting and warning not far away.

"Don't come any closer, this is where our two teams found out, you can try your luck elsewhere!" At the entrance of a cave in the 20 mining area, two armed mercenaries looked at Lin Ze cautiously.

"Let's go!" Obviously, the previous plan was too ideal, and the current situation is that everyone knows that the danger of the mining area after the E cave has increased greatly, so it is not surprising that most of the mining areas concentrated in front of the cave occupy an area to hunt insect swarms, and the team that comes late cannot find a place to hunt.

"I don't think we need to go deep into the place behind the E cave, we are just a newly formed team, we can hunt some ordinary insects in the mining area further up", Pan Cripple glanced at the casual Shu brothers with a vague gaze, and continued to add, "Not to mention that we also have a child with us, who needs to learn more survival experience." ”

"The previous mine was full of people, what do you think is left? I think Captain Shield is so powerful, as long as we don't go deep into the F cave, the general situation can definitely be handled, you must know that black-backed beetles and black-backed ants are not valuable, valuable insects are down there", Shu Ye retorted, and looked at Lin Ze eagerly, that look was particularly hot, and seemed to have a hint of worship.

"I also agree to take a deeper look, the blackback ant carapace is not worth anything at all, of course, what Lao Pan said is right, otherwise, let's take a look at the No. 21 mine near the base?" Stunned Qing should be enthusiastic here, Lin Ze agreed with Shu Ye's suggestion, but took into account Pan Lao's lame opinion a little and said in a compromise.

"Since Captain Dadun said so, let's go", Shu Hu continued, obviously more than half of the people in the team who agreed to continue going deeper, and the big boy in blue was still unassertive.

Pan Lao's lame face suddenly looked ugly, leaving the team without permission after going down to the mining area would have a bad impact on his mercenary record, the corners of his mouth twitched, and finally he didn't refute again, he lowered his head silently, and motioned for the big boy to follow, but his right hand had already tightly grasped the handle of the revolver.

The group passed by the heavily guarded fortress of Cave E, did not stop, and continued to advance along the mine road, until they came to the 21 mining area before slowing down.

The No. 21 mining area is particularly depressing, only a few muffled panting sounds can be heard in the dark and gloomy environment, and the light crystal cylinder carried with him illuminates the darkness more than thirty steps away, and there are no other teams in the entire No. 21 mining area?

"Something is wrong with the situation, why is the air so thin here, it seems to be a little difficult to breathe", Pan Cripple interjected in a low voice, "Every mining area is equipped with air manufacturing equipment, and the guard patrol of the prisoners will change the raw materials for air production from time to time, or issue tasks in the camp base, it is impossible to ignore it." ”

"Who's over there!" Not far away, a loud shout came from the darkness, and several beams of light were projected from the end of the darkness.

"Who are you! Don't come here, or we're going to shoot", Shu Ye also shouted back.

"Whew~ It turned out to be a mercenary, your own people, don't shoot, we are a small team of the criminal prisoner mercenary team", the people on the dark side seemed to breathe a sigh of relief.

"Why do you look like you're facing a great enemy, come slowly, and don't do anything that might cause misunderstanding," Pan asked in a loud voice.

"Hey, don't mention it, what's always stealing raw materials for air manufacturing in the 21 mining area, the place where the oxygen production equipment is placed in this ghost place is just near an anthill that extends in all directions, there is no way to send someone over to guard it, I really don't know if those damn insects suddenly became smarter, or they dislike that the rocks are not delicious and want to change the taste, it's really hateful, no one cares about the raw materials after they have been stolen several times", five mercenaries with drooping guns slowly walked over from the darkness, and Lin Ze and the others also lowered their guns, so as not to cause misunderstanding.

"What about mining lights? Why is it pitch black here?", Pan Lao Lame continued to ask.

"God knows, it seems that no one has come to repair it if it's broken, it's not safe down there, and it's black, it's really crazy, you can only go to the No. 22 mine if you want to hunt, the air manufacturing equipment there is still normal, but be careful, many people have died down there recently, no, I'm a little out of breath, I have to get out of here quickly."

Seeing a few passing mercenaries walking away, Pan Lao lame suggested in a low voice, "Since the 21st mining area is like this, why don't we go back first, the guards of the prisoners will mobilize resources and combat power on a large scale to come down, and they will definitely not be untargeted, and it is very dangerous to continue to go deeper." ”

"Or go to the 22 mining area to have a look, it's not far ahead, you can't come for nothing, Captain Dadun is so powerful, those mercenaries came back safely just now, I don't want to come down there", Shu Ye was naturally unwilling to give up.

"Let's go, let's go!" Lin Ze was categorical.

The team was silent and fast, running towards the darkness at the end of the road, and gradually, the air seemed to become clear, and a faint light came from the end of the distant mine.

"Slap~" There was an indiscrete sound, and the light at the end flickered tenaciously a few times, and then it was extinguished!

"What's the situation!" Shu Hu walked with a certain step and exhaled softly.

"It's nothing, the miner's lamp is in disrepair, and it is estimated that it has burned out", Lin Ze still walked in the front, his tone was brisk, and his footsteps did not stop for a moment.

"Why don't we go back to the E Cave base first to see what happens? Maybe there is a task", Shu Ye also stopped, hesitated for a moment, and whispered.

"Wait, what's that!" Shu Hu suddenly exclaimed again, his light crystal cylinder kept shining in front of him, and at the edge of the aperture, a mysterious dark blue luster flashed.

"Blueback beetle, chase after it! I saw it, it's a blue-backed silver-veined beetle, catch it, catch it and we'll send it! Shu Ye lifted himself and ran forward, not seeing that he had hesitated before.

"Don't let it run, hurry up", Pan Lao was also excited, urging the big boy in blue who acted as a crutch to speed up, "That's a blue back carapace bug, one of the three most valuable carapace underground, quick, stupid boy!" Take my leg and you're cured! ”

The dark blue beetle ran and flew, moving fast, and the group rushed into the 22 mining area, the Shu brothers ran in the front, Pan Lao Lame and the big boy were not slow, and Lin Ze followed without moving forward.

22 There were occasionally a few lights in the mining area, those were still working crystal mining lamps, and several people followed around for almost ten minutes, and ran into a cave passage that was not very spacious, and saw that the dark blue beetle was about to be blocked, and the Shu brothers in front suddenly stopped.

"Oh, my God, it's a lot~" The light crystal cylinder tied to the barrel of the gun was always open, and within the range illuminated by the aperture, dense beetles filled the narrow passage, flashing with various colors of brilliance under the light spots, "Run!" ”

The sudden light in the pitch black environment violently stimulated the beetles that climbed up and down the rock wall, and the angry swarm roared out like a cloud.

The Shu brothers went fast, ran back faster, and hurriedly took off the grenade on their waist and threw it back, a few dull explosions, dusty, and more beetles near the explosion circle flew away, but more beetles rushed up to fill the gap created after the explosion.

Pan Lao was lame and finally caught up, the Shu brothers staggered over, his eyes were fixed, and then he was shocked, hurriedly shook off the big boy's support, took off the light pressure rifle behind him as a crutch, and ran backwards lifelessly, not much slower than the Shu brothers.

The big boy in blue was stunned by the sudden change, especially when Pan Lao pushed him lamely, and he was stunned in place.

"Bang!" The sound of gunfire echoed through the narrow passage, and the silver beetle that leapt down from the top of the passage and pounced on the big boy was directly shot by a single shot.

"What a daze, let's go!" Lin Ze shouted angrily, followed by two faster shots, accurately hitting the fragile abdomen exposed by the beetle in mid-air, killing the flying beetle.

The boy finally came back to his senses, turned his head and ran, Lin Ze turned around, fell last, did not look back, but held the pistol upside down in his right hand, and the gunshots rang out one after another, shooting the beetles that pounced on his back one by one.

The gun rang out endlessly, the 15-round magazine was quickly shot empty, Lin Ze took advantage of the situation to lift the gun and lightly pressed the magazine lock, the empty magazine fell, the pistol moved to the side of the leg, and the little finger lightly touched the bottom of the spare magazine, with a click, the magazine was replaced, and then the thumb quickly crossed the bolt reset button, and in just a moment, the gun sounded again.

Pan Lao lame fell not far behind the Shu brothers, listening to the continuous gunfire in the aisle behind him, it seemed that the sound of gunfire and gunfire were reverberating in his ears, he didn't dare to look back, for fear of delay, suddenly, Shu Ye in front of him didn't know where to find a slender small glass bottle, twisted around in the run, raised his hand and threw it back, the corner of his mouth seemed to have a hint of a smile, Pan Lao was lame, and hit the rock wall of the passage in a hurry, the glass bottle almost flew over his scalp, and a green light flashed in the bottle in his eyes.

"Bang~" The glass bottle tray turned down, and finally smashed at Lin Ze's feet, the liquid splashed, and the sound of the bottle breaking echoed in everyone's hearts.

The green one is ...... Pheromones, Pan Lao Lame suddenly realized in his heart......
