At this moment, deep in the mine tunnel, when the smoke and dust from the collapse gradually subsided, Susanna came over with a gun to look for An Feng. She found An Feng wandering among the ruins in the oblique tunnel not far from the central transfer platform.
The rocks here are very hard, almost all basalt, granite, and copper ore. The first two types of rocks are the hardest among stones. The large pieces of collapsed rock blocked the vertical lift passage and also blocked several oblique mine shafts near the central transfer platform. However, because the rocks here are relatively hard, the vertical lift passage at the mine mouth has been specially reinforced. Therefore, a large area The soil collapse did not block all the tunnels. Some of the oblique tunnels were only blocked for a few meters. As for the deeper tunnels, An Feng and Susanna were completely free to move.
Susanna stood at the entrance of the blocked tunnel. She didn't have An Feng's ability to see at night, so she took the risk to light up the flashlight, shined a light on the wall of the cave, made a rough estimate, and interjected: "The tunnel is blocked for about meters." What are you going to do?"
An Feng looked up at the top of the tunnel and replied: "If they want to come in and we want to go out, this tunnel must be opened."
Suzanne asked again: "The ventilation system has stopped operating. How many hours can our oxygen be maintained?"
"Don't worry, the underground tunnels in the mine are about hundreds of kilometers long. There is enough oxygen left in these tunnels for the two of me to breathe. In addition, we also have a regenerative oxygen system dedicated to submarines, so the oxygen is Don¡¯t worry about the problem, I just worry about food and water.¡±
Susanna reached out and rubbed her temples, a map of the tunnels unfolding in her mind.
Most of the criss-crossing tunnels in the mine are excavated along the veins. Wherever the veins extend, the tunnels will be excavated. Therefore, the directions of most tunnels are veryirregular.
Here, some branch roads are for the convenience of transporting ore, and some tunnels exist to increase the safety factor underground. The entire mine tunnel, after half a century of mining by more than a thousand people, has become as tangled as a spider web.
What's particularly critical is that this spider web is a three-dimensional structure. Sometimes the two tunnels are only separated by a thin rock wall and are no more than 3 meters apart, but they intersect in space, and people walking in the tunnel have no idea. Separated by a thin layer of rock, there is another tunnel next to it.
Determining the direction of the tunnel requires advanced instruments and spatial imagination. The workers in the previous mines did not have these equipments, so the maps of the mine tunnels they left behind were flat, and some of the contents were even drawn incorrectly.
Since Susanna moved in here, in order to make it easier for her to escape and to move forward and retreat freely when necessary, she used advanced instruments to survey and re-determine the three-dimensional map of the entire tunnel. In addition, she excavated some adjacent tunnels and added many new contents to the tunnels - these new contents have been separated from the original plan tunnel map left by the copper mining company.
"The original Excavation Group 1 and 2 of the copper mining company dug the deepest tunnels and the strongest rock walls. The Excavation Group 7 was a newly dug tunnel - the mining groups I am talking about are all the original mining groups of the copper mine. . If we want to evade, I suggest we first hide in the tunnel of Mining Group 7. The equipment there is relatively new, and maybe we can restore the power inside.
"As for food and water, don't tell me that you don't have any storage on hand. You can take out all kinds of weapons without interruption - no, no, no, I can't think about this issue and can't remember it. I'm afraid that if I remember this, once I If you are arrested by them, your secret will be exposed. This is what you are worried about, right?
Don¡¯t worry, I will try my best to forget and not care. You just do your thing. I can¡¯t see or hear you, okay? "
An Feng thought for a moment and nodded immediately: "Okay, we have reached a tacit understanding on this issue - I can arrange some oxygen isolation curtains in the tunnel of the seventh mining group, move our oxygen regenerator to that tunnel, and then Seal this tunnel It seems that the long-range offensive and defensive battle is over, and it is time to enter the contact battle. "
The tunnel is so deep, with branches so densely spread in all directions, that it would take unimaginable effort to install monitoring equipment at each branch entrance. Instead of wasting all your efforts on useless work, it is better to take advantage of these ten days to rest and prepare a way out for yourself.
At this time, the mercenaries on the ground were also very busy.
The next day, a support team entered the mine with a large shield vehicle. At the same time, another mercenary team entered a nearby town - at this time, the mercenaries had begun to look for the anonymous original owner of the mine. Be prepared to stop the mine owners from disturbing you.
With the submarine captain¡¯s promise, the mercenary squadron leader did not hesitate to pay the price. He sent people to sneak into the mine¡¯s vertical lift to search for Arnold¡¯s wreckage. After discovering that Arnold's wreckage was buried under thick rocks, a team of mercenaries was dispatched to go deep into the vertical lift tunnel and install a new track inside the tunnel entrance.
In three days, the new track was laid out, and twoThe soldiers drove the shield car, entered the tunnel entrance from the horizontal track on the ground, and then entered the rock jam area along the newly laid track. With a roar, the drilling shield in front of the shield vehicle began to operate at high speed.
The new shield car is smaller than the original freight elevator, so the deformation of the passageway entrance has no effect on it. Several newly laid tracks firmly fix the body of the shield car, and the shield car with full power is moving towards it completely and continuously. Drilling down.
The rock layer is very hard, so the mercenaries have replaced the overheated drilling shields several times, but they have no intention of slowing down the drilling speed - there are people who are willing to bear the money, and the mercenaries have no intention of saving it for others.
This kind of shield truck was originally used to lay oil pipelines. The pipe mouth drilled by it is not wide. People need to squat down to enter the pipe mouth, but at least they don¡¯t have to crawl forward.
While the shield vehicle is drilling downward, it is laying thick steel pipes in the drilled cavewell, the pipes are actually oil pipes.
After drilling for two days and two nights, the shield car drilled into Arnold's body. Because the steel plate on Arnold's body was very strong, the shield car could not drill further. Two maintenance teams went down to the mine mouth and began to dismantle Arnold's remains
This dismantling work lasted for three days. When Arnold's front armor skirt was dismantled, the shield vehicle drove back into the cave and began drilling.
It took one day longer to open the tunnel than An Feng estimated. When the first ray of fresh air in the tunnel poured into the central platform, the sensor at the entrance immediately issued a warning. Deep in the tunnel, Susanna and An Feng were resting with their eyes closed. Wake up immediately.
The thick rock layer blocked Susanna's hearing, but it could not block An Feng's vision. In An Feng's super-vision sense, a team of nine people went down to the central transfer platform along the drilled channel. They dispersed and occupied various areas. After the passage, a steady stream of mercenary teams began to occupy the central transfer platform, and the shield vehicle also staggered into the center of the platform.
An Feng held Susanna's hand with his backhand, and their powers immediately merged. An Feng immediately vaguely heard some voices around the platform. The voices were not clear, only a few vague words. And because of this handshake, Susanna suddenly saw the scene near the transfer platform. The scene she saw was particularly clear, far clearer than the sound she heard.
The mercenaries are communicating with each other about the investigation situation. After a while, the mercenary squadron leader descended to the center of the platform. The nine-member mercenary team that arrived earlier reported the situation to the captain: "Boss, there are at least 9 tunnels branching out from this platform. Four of them have been seriously buried by soil. Five tunnels are slightly blockedwhat should we do now?"
The captain turned his head, and the mercenary A beside him opened his 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 There is no need to calculate the cost of mining, 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 reminded Mercenary A impatiently: "Tell me the important point?"
Mercenary A swallowed and continued: "On the drawings left by the mining company, the distribution of the old tunnels does not have three-dimensional coordinates. There are two new tunnels marked with spatial coordinates. I guess it is because the equipment they use becomes more and more complex towards the end." modernization."
Under the scolding gaze of the squadron leader, Mercenary A skipped the previous elaboration and went straight to the point: "Due to incomplete information, the three-dimensional diagram of the tunnels we constructed is just our own guess. According to the diagram, two of the nine tunnels are main In the main tunnel, all the ore must be collected into these two main tunnels, and then the ore will be transported out through the rails.
In addition, one tunnel is a ventilation channel, and two tunnels have become landfill tunnels because they have no mining value. The excavated gravel and useless soil are poured into these two tunnels. Therefore, we do not need to dig out all the congested tunnels. We can give up at least two exhaust gas channels.
I think we only need to dig one of the main tunnels, and then search along this main tunnel If no trace of the two people is found in this main tunnel, the tunnel will be blocked. Go search for another main tunnel. "
The squadron leader waved his hand: "As you say, we don't have much time, so hurry up and don't delay."
Mercenary A pointed at the tunnel map and said: "It doesn't matter. If we want to speed up the action, we don't need to transport the excavated soil out of the mine entrance. The soil can be piled in this tunnel. This tunnel is the oldest tunnel in the mine. There are no more The mining value is gone, and the power supply and rails inside have been dismantled. I guess the two people will not hide here, because there is no way to survive here. "
"Okay, that's it."
After the squadron leader inspected the defense layout of the central platform, he returned to the ground. At this time, most of the mercenaries had moved to the vicinity of the central platform, leaving only the squadron leader and a five-person team on the ground. The reason why the squadron leader stayed on the ground to conduct command was not because he was timid, but because he wanted to maintain a clear connection with the satellite. The shield car roars againCome.
An Feng and Susanna nodded to each other in the dark. Susanna couldn't see An Feng's face, but she could feel An Feng's determination.
After walking a few steps into the dark cave, Susanna stopped and turned to ask An Feng: "The first two times I asked for your help, you refused. Why did you agree to me without hesitation this time? Oh, I What kind of relationship between the two of us is worth giving up everything for me?"
Before An Feng could answer, Susanna immediately asked: "Do you want me to recover my past memories? When my memory is restored, how should our relationship be positioned?"
An Feng had already reached the entrance of another tunnel at this time, and he responded without looking back: "Guess."
An Feng and Susanna walked through a horizontal tunnel. This tunnel made seven turns and eight bends, connected several mining tunnels in series, and finally converged at the No. 1 Tunnel. Therefore, An Feng and Susanna each went around in circles, and finally stayed at the No. 1 Tunnel. Near the tunnel, the spatial distance between the two is about RU0 meters, but there is no straight line connecting them.
Near the tunnel, the rumbling sound of excavation echoed. Although tunnel No. 1 was not excavated at this time, the cave effect amplified the sound of the excavator, making An Feng's low voice muttering to himself impossible to hear.
"I'm really looking forward to it, I wonder what the other one looks like," An Feng said to himself in a low voice as he stroked the trembling cave wall with his hand.
In the direction of the central platform, among the mercenaries standing at the entrance of the central tunnel, at least one was of the same nature as An Feng and Susanna. At this time, An Feng had already felt the resonance phenomenon of the bones in his body, and Susanna must have felt it too.
As the super visual sensation passed, there were nine people standing at the entrance of the tunnel. They were divided into three groups and squatted in a perfect glyph shape at the entrance of the tunnel. This is an oblique downward tunnel. Because it has to transport ore, the slope of the tunnel is not very large. The vibration caused by drilling keeps causing the stones to slide down. The rolling stones increase the noise in the tunnel, so much so that the breathing of several people at the entrance of the tunnel is heard. Become insignificant.
But all the noise finally stopped. When the tunnel mouth was finally drilled through, the shield truck turned off. The shield-shaped drill bit in front idled along the inertia for a while. When the drill bit was empty drilling, two drill bits, one on the left and one on the right, The three-person mercenary group had already bypassed the train and advanced into the tunnel along the gap of the shield-shaped drill. At the same time, the last three-person mercenary group made no big movements. One of the three people ran forward two steps. Seeing the remaining two people standing still, he immediately stopped and turned to look at his companions in surprise.
Among this group of people, the commando in the center was a black man. The black man had a serious face. He stretched out his hand and made a careful gesture. Mercenary B, who set off early, nodded. Mercenary C, who was standing next to him, He responded with a gesture, and then the black mercenary Ding waved forward. The three of them carefully walked around behind the shield-shaped drill bit of the shield car, and signaled the driver of the shield car to start the shield car and move forward slowly.
The suspect was finally found. The person who triggered the resonance effect between An Feng and Susanna was Mercenary C or Mercenary D. Maybe both of them, but the last black mercenary D was more suspicious.
The two mercenary groups that set off early began to search forward and backward in a search formation. When they reached the first fork in the tunnel, one group of mercenaries released the robot rats, which continued to go deeper along the tunnel. The mercenaries held remote controls in their hands and observed the scene detected by the robot mouse on a screen the size of a mobile phone.
In the distance, Susanna listened to the movements of the mercenaries. She could only hear the sound of the two wheels of the robot mouse rolling. The two groups of mercenaries in front of them were gesturing to each other in sign language, even though what they said was very complicated.
An Feng couldn't hear the sound, but he could see the soldiers' sign language.
The person responsible for controlling the robot mouse gestured in sign language: "I found three lateral forks, but my robot mouse has reached the control limit. If the mouse goes forward, it will be out of the control range of the remote control signal."
Of course, this type of expensive spy equipment is not like civilian remote control aircraft, which will completely lose contact once it goes out of the remote control range. This mouse has an automatic return program in its body. Once it cannot sense the remote control signal, it will automatically detect according to the program and then automatically return - the Mars rover is equipped with such a program, so that it can automatically execute without control. own survey responsibilities.
The corporal next to him waved his hand, signaling the soldier controlling the robot mouse to give up active control. The soldier sighed with distress and let go of the remote control lever.
The robot mouse continued to roll forward. At this time, there was no remote control command, and it could only roll forward. During the rolling process, the mouse discovered two more diagonal tunnels, but because the robot mouse was unable to do so at this time, In the control state, it cannot turn the lens to the two dark tunnels, and can only continue to roll forward at its own speed.
At this time, the three mercenaries B, C, and D continued to advance. They were always hiding behind the shield car, especially the last two mercenaries. The two guns in their hands, one long and one short, were always between An Feng and Wandering near the tunnel where Susanna is hiding.??
An Feng was not sure which of the two men was the trump card. The other party could only vaguely sense the existence of two dangerous targets, but could not determine the specific location of the danger.
So, An Feng waved his hand, and a mobile phone screen appeared on his hand. There were several light spots on the screen. The infrared rays emitted by the shield car were the strongest. The light spots it formed blocked the three mercenaries behind him and also caused the six mercenaries in front to The stains are very inconspicuous.
As soon as An Feng's cell phone screen lit up, the black mercenary Ding jerked his neck and subconsciously shouted: "Lie down."
"However, the black mercenary Ding Huihuang's body never exceeded the shield.
The six mercenaries in front of the attack did not question this order. They quickly fell to the ground, but they did not know where the danger was, so they could only turn their guns blankly.
Although these mercenaries are highly skilled, they are not An Feng and Susanna. They cannot detect obstacles in the dark tunnel, so they tie flashlights to the muzzles of their guns, and the flashlight lamp posts flash back and forth as the muzzles of their guns drift.
Because of this shout, the mercenaries stopped advancing. After everyone waited for a moment, they felt nothing happened. One mercenary turned over and turned to face the sky, lying on his back. He asked the black mercenary Ding behind the shield loudly: "What's going on?" What happened?"
At this time, An Feng's preset heavy sniper rifle was activated. The infrared low-light night vision device on the muzzle scanned the tunnel entrance. This low-light night vision device only had a visual distance of 25 meters. Although he could barely distinguish a few servants However, due to the interference of the shield vehicle, the accurate positions of several mercenaries could not be captured on the scope.
