Chapter 412: Contact Battle

At this moment, in the depths of the mine tunnel, when the smoke and dust from the collapse gradually subsided, Suzanne came to look for An Feng with a gun, and she found An Feng who was wandering around the ruins in the diagonal tunnel not far from the central transfer platform.

The rocks here are hard, almost all basalt and granite, as well as copper ore. The first two types of rocks are the hardest of the stones. The large rock block of the collapse blocked the vertical lifting passage, and also blocked several inclined mine shafts near the central transfer platform, but because the rock here is relatively hard, the vertical lifting passage at the mine head has been specially reinforced, therefore, the large-scale soil collapse did not cause all the tunnels to be blocked, and some of the inclined tunnels were only blocked for a few meters, as for the deeper tunnels, An Feng and Suzanne were completely free to move.

Suzanne stood at the mouth of the clogged tunnel, she didn't have An Feng's ability to see at night, so she took the risk of lighting a flashlight, shining on the walls of the cave, making a rough estimate, and interjecting: "The tunnel is blocked for about 20 meters...... What are you going to do? ”

An Feng looked up at the top of the tunnel and replied, "They want to come in, we want to go out, and this tunnel must be opened." ”

Suzanne asked, "How many hours can we maintain oxygen when the ventilation system stops?" ”

"Don't worry, the underground tunnels in the mine add up to about 100 kilometers long, and the residual oxygen in these tunnels is enough for the two of me to breathe, plus we also have a set of regenerative oxygen system for submarines, so I don't have to worry about food and water."

Suzanne reached out and rubbed her temples, and a map of the tunnel unfolded in her mind.

Most of the tunnels criss-crossing the mine are mined along the veins, where the veins extend, and most of the tunnels are very ...... There is no pattern.

Here, some forks are used to facilitate the transportation of ore, and some tunnels are stored to increase the safety factor of the underground. And the entire tunnel of the mine, after half a century of excavation by more than 1,000 people, has become like a spider's web.

The most important thing is that the spider web is a three-dimensional structure, and sometimes the two tunnels are only separated by a thin rock wall, only 2 or 3 meters apart, but they are staggered in space, and the person walking in the tunnel is completely unaware that there is another tunnel next to the thin layer of rock.

Determining the direction of the tunnel requires advanced instrumentation, as well as spatial imagination. The workers in the mine did not have these equipment, so the tunnel diagram they left behind was planar, and some of the content was even drawn incorrectly.

Since Suzanne moved in, in order to make it easier for herself to escape and be able to move in and out when necessary, she used advanced equipment to survey and redefine the three-dimensional view of the entire tunnel. On top of that, she excavated some of the adjacent tunnels and added a lot of new content to the tunnels – new elements that were out of the original plan of the copper mining company.

"Originally, the first and second mining groups of the copper mining company dug the deepest tunnels and the strongest rock walls, and the seven mining groups were newly dug tunnels -- the mining groups I was talking about were the original mining groups of the copper mine. If we're going to dodge, I'm going to take refuge in the tunnels of the seven mining groups, where the equipment is relatively new, and maybe we'll be able to restore the power inside.

"As for food and water...... Ha, don't tell me that you don't have a store on hand, you can take out all kinds of weapons without interruption - no, no, no, I can't think about it, I can't remember it, I'm afraid that if I remember this, once I am captured by them, your secret will be exposed. That's what you're worried about, isn't it?

Don't worry, I'll try my best to forget, I don't care, you just do yours, I can't see or hear, okay? ”

An Feng thought for a moment, and immediately nodded: "Okay, we have reached a tacit understanding on this issue - I can arrange some oxygen insulation curtains in the tunnel where the seven groups are excavated, move our oxygen regenerator into that tunnel, and then close this tunnel...... It seems that the long-range offensive and defensive battle has ended, and the next time should be the contact battle. ”

The tunnel is so deep and so dense with branches that it would take unimaginable effort to install monitoring equipment at each branch opening. Instead of wasting your efforts in vain, it is better to take advantage of these ten days to rest and recuperate, and lay a back road for yourself by the way.

At this time, the mercenaries on the ground were also busy.

The next day, a support team enters the mine with a large shield cart, while another mercenary team enters a nearby town - by this time, the mercenaries have begun to search for the mine's anonymous original mine owner, preparing to stop the mine owner's interference.

With the promise of the submarine captain, the mercenary squadron leader spared no expense, and he sent people to infiltrate the vertical lift passage of the mine to find Arnold's wreckage. Finding Arnold's wreckage buried under a thick layer of rock, a team of mercenaries was sent out to go deep into the vertical lift passage and install new tracks inside the passage mouth.

In three days, the new track was laid, and the two mercenaries drove the shield cart from the horizontal track on the ground to the tunnel entrance, and then followed the newly laid track into the rocky blockage. With a roar, the drill shield in front of the shield cart began to move at high speed.

The new shield car is smaller than the original elevator freight elevator, so the deformation of the passage mouth has no effect on it, and the newly laid tracks firmly fix the body of the shield car, and the shield car with full horsepower is completely and constantly drilling down.

The rock layer was very hard, and the mercenaries had changed their hot drill shields several times, but they had no intention of slowing down the drilling - someone was willing to pay for it, and the mercenaries were not going to save it for others.

This kind of shield car was originally used to lay oil pipelines, and the pipe mouth it drilled out was not wide, and people needed to squat to enter this pipe mouth, but they didn't have to crawl forward.

As the shield truck drilled downward, it laid thick steel pipes in the drilled caverns...... Well, that pipe is actually a tubing.

After two days and two nights of drilling, the shield truck drilled Arno's body, because the steel plate on Arnold's body was very strong, the shield truck could not drill, and the two maintenance teams went down to the mine mouth and began to dismantle Arno's wreckage......

The dismantling lasted three days, and when Arnold's front armor skirt was dismantled, the shield truck re-entered the cave and began drilling.

When the first ray of fresh air in the tunnel poured into the central platform, the sensors at the entrance of the tunnel immediately issued a warning, and in the depths of the tunnel, Suzanne and An Feng, who were resting with their eyes closed, immediately woke up.

The thick layer of rock blocked Suzanne's hearing, but it couldn't block An Feng's vision, in An Feng's transcendent sense, a team of nine people went down to the central transfer platform along the drilled passage, and after they scattered and occupied the various passages, a steady stream of mercenaries began to occupy the central transfer platform, and the shield cart also staggered into the center of the platform.

An Feng held Susanna's hand with his backhand, and the abilities of the two suddenly merged. An Feng immediately faintly heard a little talking around the platform, and the voice was not clear, only a few vague words. And because of this handshake, Suzanne suddenly saw a scene near the transfer platform, and the scene she saw was exceptionally clear, far clearer than the sound she heard.

The mercenaries were exchanging information with each other. After a while, the mercenary squadron leader went down to the center of the platform, and the nine-person mercenary team that arrived early reported the situation to the captain: "Chief, there are at least 9 tunnels separated from this platform, four of which have been buried by the mud, and the other five tunnels are slightly blocked...... What do we do now? ”

The captain turned his head, and the mercenary A beside him spread out the computer, and introduced quickly: "This is an old mine, and the copper content of the ore produced is not high, in the past era, under the planned economy, copper mining does not need to calculate the cost, so the equipment is updated very slowly, and the old equipment of the copper mine cannot estimate the horizontal distribution of the mine." ”

The squadron leader impatiently reminded Mercenary A: "Tell me the point? ”

Mercenary A swallowed and spat, and continued: "On the drawings left by the mine company, the distribution of the old tunnels does not have three-dimensional coordinates, and two of the new tunnels are marked with spatial coordinates, I guess it is because the more they get to the end, the more modern the equipment they use. ”

Under the reproachful gaze of the squadron leader, Mercenary A omitted the previous layout and went directly to the point: "Because the information is incomplete, the three-dimensional map of the tunnel we built is just our own guess. According to the diagram, two of the nine tunnels are trunk tunnels, and all the ore is collected on these two trunk tunnels, and then the ore is transported by guò rails.

In addition, one tunnel is a ventilation tunnel, and two tunnels have no mining value, so they become landfill tunnels, and the excavated gravel and useless soil are poured into these two tunnels. So those congested tunnels don't have to be dug all, at least two exhaust gas channels, we can give up,

I think we just need to dig up one of the trunk tunnels and search along this trunk tunnel...... If you can't find any trace of the two men in this trunk tunnel, block the tunnel and search for another trunk tunnel. ”

The squadron leader waved his hand: "Do as you say, we don't have much time, hurry up and don't delay." ”

Mercenary A pointed to the tunnel diagram and said, "It's okay, if we want to speed up the action, we don't need to transport the excavated dirt out of the mine mouth, the dirt can be piled up in this tunnel, this tunnel is the oldest tunnel in the mine, there is no mining value anymore, the power supply and rails inside have been dismantled, I guess those two people will not hide here, because there is no way to survive here." ”

"Okay, that's it."

After checking the defensive arrangements of the central platform, the squadron leader returned to the ground, and by this time, most of the mercenaries had moved to the vicinity of the central platform, leaving only the squadron leader and a team of five on the ground. The squadron leader stayed on the ground to command, not because he was timid, but because he had to maintain an unobstructed connection with the satellite. The shield cart roared again.

An Feng and Suzanne nodded to each other in the dark, Suzanne couldn't see An Feng's face, but she could feel An Feng's resoluteness.

After taking a few steps into the dark cave, Suzanne stopped, turned her head and asked An Feng: "The first two times I asked for your help, you refused, why did you agree to me without hesitation this time?" Oh, what is the relationship between the two of us, worthy of your willingness to abandon a qiē for me? ”

Without waiting for An Feng to answer, Suzanne immediately asked, "Do you want me to recover my memories of the past?" When my memory is restored, how should our relationship be placed? ”

An Feng had already walked to the mouth of another tunnel at this time, and he responded without looking back: "Guess." ”

An Feng and Suzanne walked a horizontal tunnel, which made seven winds and eight bends, connected several mining tunnels in series, and finally converged to the No. 2 trunk tunnel, so An Feng and Suzanne each went around in a circle, and finally stayed near the No. 2 trunk tunnel, the spatial distance between the two was about 800 meters, but there was no straight line connection road in the location.

Near the main tunnel, the rumbling sound of excavation echoed, although the No. 2 tunnel was not excavated at this time, the cave effect amplified the sound of the excavator, so that An Feng's low voice to himself could not be heard.

"I'm really looking forward to it, I don't know what the other one looks like", An Feng stroked the trembling cave wall with his hand and whispered to himself.

In the direction of the central platform, among the mercenaries standing at the mouth of the No. 2 central tunnel, at least one of them was a person of the same nature as An Feng and Susanna, and at this time An Feng had already felt the resonance of the bones in his body, presumably Suzanne had also experienced it.

As the supervisual sensation passed, there were nine people standing at the mouth of tunnel No. 2, squatting in three groups in a zigzag shape at the mouth of tunnel No. 2. This is a diagonal downward tunnel, because the ore is to be transported, so the slope of the tunnel is not large, the vibration caused by the drilling keeps causing the stones to slide down, and the rolling stones increase the noise in the tunnel, so that the breathing of several people at the entrance of the cave becomes undetectable.

But all the noise finally stopped, when the tunnel mouth was finally drilled, the shield car turned off, the shield drill bit in front of it, idling along the inertia for a while, when the drill bit was empty, a left and a right two mercenary three-person team had bypassed the bullet train, along the gap of the shield drill bit into the tunnel, at the same time, the last group of three mercenaries did not make a big move, one of the three ran forward two steps, seeing the remaining two standing in place and not moving, he also immediately stopped, twisted his face and looked at his companion in surprise.

Among this group of people, the commando in the center is a black man, this black man's face is very solemn, he stretched out his hand and made a careful gesture, mercenary B who set off in advance nodded, mercenary C standing next to him gestured back, and then the black mercenary Ding waved his hand forward, and the three of them carefully went around the shield drill bit of the shield car, and signaled the shield car driver to start the shield car and move forward slowly.

The suspect was finally found, and what triggered the resonance effect between An Feng and Suzanne was Mercenary C or Mercenary Ding, maybe both of them, but the last black mercenary Ding was a little more suspicious.

The two teams of mercenaries who set off in advance began to search in a search formation, and when they reached the first fork in the tunnel, one of the mercenaries released the machine qì mouse, and the machine qì mouse continued to go deeper along the tunnel, and the mercenaries held the remote control in their hands, observing the scene detected by the machine qì mouse on a screen the size of a mobile phone.

Suzanne listened intently to the mercenaries in the distance, and she could only hear the sound of the two wheels of the machine mouse rolling, and the two groups of mercenaries in front of her were gesturing with each other in sign language, even if the content they said was complicated.

An Feng couldn't hear the sound, but he could see the sign language of the soldiers.

The person in charge of controlling the mouse used sign language to make an analogy: "I found three horizontal forks, but my mouse has reached the limit of control, and the mouse goes further, and it is out of the range of remote control signal control." ”

Of course, this kind of expensive espionage equipment is not like civilian remote-controlled aircraft, once it is out of the remote control range, it will completely lose contact. This mouse is set up with an automatic return program, once it does not sense the remote control signal, it will automatically survey according to the program, and then actively return - the Mars rover has set up such a program, so that it can automatically perform its own exploration duties without control.

The corporal next to him waved his hand and motioned to the soldier who controlled the machine to give up active control, and the soldier sighed in distress, and he let go of the remote control stick.

The machine qì mouse continued to roll forward, at this time, there was no remote control command, it could only roll forward one by one, and in the process of rolling, the mouse found two more oblique tunnels, but because the machine qì mouse was in an uncontrollable state at this time, it could not turn the camera to the two dark tunnels, and could only continue to roll forward at its own speed.

At this time, the three mercenaries B, C, and D continued to move forward, and they always hid behind the shield cart, especially the last two mercenaries, and the two guns in their hands, one long and one short, were always moving near the tunnel where An Feng and Suzanne were hiding.

An Feng couldn't be sure which of these two people was the trump card, and the other party could only vaguely feel the existence of the two dangerous targets, but he couldn't determine the specific location of the danger.

So, An Feng shook his hand, and a mobile phone screen appeared in his hand, on the screen were several light spots, and the infrared rays emitted by the shield car were the most intense, and the light spots it formed blocked the three mercenaries behind him, and also made the six mercenaries in front of him very inconspicuous.

As soon as An Feng's mobile phone screen lit up, the black mercenary Ding's neck shrank suddenly, and he subconsciously roared: "Lie down." ”

However, the black mercenary Ding shouted and shouted, and his body never exceeded the shield.

The six mercenaries in front of them did not question this order, and they quickly fell to the ground, but they did not know where the danger was, so they could only turn the muzzle of their guns in a daze.

Although these mercenaries were skilled, they were not An Feng and Susanna, and they could not detect obstacles in the dark tunnel, so they tied flashlights to the muzzles of their guns, and the flashlight posts flashed around with the drift of their muzzles.

Because of this shout, the mercenaries stopped advancing, everyone waited for a while, and felt that there was no movement, and one of the mercenaries turned over, changed to a supine posture facing the sky, and asked the black mercenary behind the shield in a loud voice: "What's the matter?" What happened? ”

At this time, An Feng's preset heavy sniper rifle started, and the infrared low-light night vision device on the muzzle scanned the tunnel mouth, this low-light night vision device was only 25 meters away, although it could barely distinguish the shape of several mercenaries, but because of the interference of the shield car, the exact location of several mercenaries could not be captured on the scope.
