Starting from Zero

"It's up to you."

"Understood." Ivorite stopped in front of the passage, and then folded the top of his arms forward. A pair of hydraulic shears. Reaching out to withstand one of the diagonal support beams, the hydraulic shears immediately began to add force, only to hear a clinking sound, the steel beam thick with adult thighs was cut neatly, and then Ivorite grabbed the middle section and moved backwards. One throw away the obstructive beam that was at the entrance.

The remaining part after clearing the first beam is treated in the same way as before. When you see the obstructing beam, you cut it on both sides and throws the middle part out. Of course, not all positions are so convenient. The reason why some places keep their original appearance is entirely because the supporting beam supports the upper stone. Once the supporting beam is removed, the upper stone starts to fall, but this It's not a matter for Inverite. No matter how big the stone is, he can just take it out and throw it away, even if it's too big, it can get stuck and cut it into small pieces before throwing it out.

In this way, we quickly passed through this passage, and then we saw a large space in front of us. This place should be the passage extending in from the outside, but it was blocked by the collapsed earth and rock in the middle. There was no collapse here, so it still looked quite wide.

The eight people who came with us are not only guides, they must also understand the structure of underground tunnels. It can even be said that these people are actually experts in this area, but they are all based on experience, nothing That's it for the theory.

One of the guides looked at the situation here and said: "It looks like the collapse situation below is not as serious as expected."

"You didn't come to check it before. Is it?" I asked slightly surprised.

The guide was quite helplessly said: "We are not like you. We don't dare to move the supporting beams that are in the passage. Simply no one dares to come in."

"No. Ah!" I was puzzled while looking at the information in the spirit net network and said: "I saw a robot dog in Longyuan's support materials! Why didn't it come in?"

This robot dog is actually the same robot dog we used when we dealt with the human traitors in the United States last time. This robot dog is not entirely military equipment. It doesn’t look very good, but it’s us. An important profitable project of Longyuan, because the application range of this robot dog is too broad.

Let’s not talk about it on the battlefield. This thing runs faster than motorcycles, and its armor protection is better than light tanks. More importantly, it is flexible in dodge and it is difficult to be hit, whether it is a strong attack or a defense. Corridor and street fighting are all top equipment. Many soldiers on the battlefield have special feelings for this robot dog, because these robot dogs on the battlefield are more reassuring than their comrades. In addition, these robot dogs can also be used for mine clearance and explosion. For example, if you encounter a suspected roadside bomb or something, you can let the robot dog go up and have a look. If it really explodes, at least there will be no casualties, and the robot dog itself is also very It will rarely be destroyed by car bombs. After all, its protective effect is close to that of a light tank, and its own weight and volume are small, the explosive force it withstands is not too high, and the survival rate is very high. In addition, the robot dog is also the best choice when you need to drill the ventilation pipe or the sewer. The front cross-sectional area of ​​this thing is very small, and it can enter the narrow passage that people can't enter. Moreover, there are wheels in the middle of the paws. , It is much faster than people in the ventilation pipe or sewer, which is very easy to use.

The above is still in the scope of military use, and there are still great achievements in civilian use.

The civilian version of this robot dog is mainly divided into three major models: enhanced version, standard version, and home version.

The enhanced version is actually a simplified model of the military version. Its armor strength is only half that of the military version. It can withstand close-range shrapnel damage. As long as it is not hit directly, ordinary rocket launchers will not produce anything to it. Killing effect, except for the direct hits of anti-material weapons and individual rocket launchers, it can basically ignore the individual weapons, so it is very useful for the police department or company preservation, banking, armed escort and other industries. thing. Of course, this model has no weapons. Except for a few military versions, most robot dogs, including more than half of the military versions, are not equipped with weapons. After all, the main function of the robot dog is not used as a firepower point.

In fact, the enhanced version is enough for most civilian industries. After all, even if this thing has no weapons, it is really easy to kill people, because it doesn’t matter whether it is a sharp like the retractable blade on its claws. The teeth in the claw or the mechanical mouth are enough to hurt people. Of course, the civilian version of the tooth is not a high-frequency vibrating blade, but just an ordinary metal spike. But think about the mouth like a trap with small dagger-like fangs, it is definitely not a joke to be bitten. What's more, the bite force of this thing is enough to bite the car engine out of the hole.

The standard version is much weaker than the enhanced version. The enhanced version is a simplified model after reducing the material strength and removing some functions on the basis of the military version, but it is still a military type in essence, but the standard version is different. This model is an independent version of another design, which is very different from the military version. The first is that this version has a lot of appearance. There are military versions that look like a robot dog, and some are deliberately made into the shape of a plush toy.

This standard version is weaker than the enhanced version in all aspects. The shell is only aluminum alloy, which can hold ordinary pistol bullets, but some huge might pistols can still be fired if they are too close. Wear it, but it's more than enough to deal with human bodies anyway. In addition, the internal skeleton system of this model does not use high-strength military special steel but is divided into many models. The more expensive ones use titanium alloy or carbon fiber, and the cheaper ones are ordinary steel or aluminum alloy. Look anyway. What model do you want? The shell of this model is actually not static. If you like it, there are armor shells for sale. Of course, the price is ridiculously expensive, but the rich will not care.

In fact, in addition to the materials, the computer performance and battery performance of the standard version and various internal equipment are actually weaker than the military version and the enhanced version. This model is actually used as a security guard for ordinary companies. It is used, after all, not every company can buy a security robot. In contrast, the robot dog is much cheaper.

Needless to say, the home version is for ordinary person to buy and play at home. Of course, it’s not really a toy for you. You can use it as a trailer when you go out to buy a dish, and you can carry it back home with less than 50kg. When you are crazy in the mall, you can carry a bag part-time, and you can use it as a stool when you’re tired. Beautiful girls can also be bodyguards when they go out. Although more than half of the shells in the home version are only engineering plastics, as long as the other party does not have a gun, this thing can still easily bring down one or two strong men, even if the other party has many people. It's okay to buy you time to escape. What's more, this gadget has its own networking function. You only need to call the police. This gadget can immediately connect you to the police station's network, and it is faster than calling the police.

Of course, this home version has more than that, and there are actually many derivative functions. For example, the plush version of the automatic electric heating function can be used as a hot water bottle in winter. It can also be used as an emergency power supply during a power outage. It is still possible to temporarily replace the lighting or flashlight, and it can also be connected to an external electrical appliance. Although the air conditioner or rice cooker cannot be used, it is okay to charge personal mobile terminals. In addition, people who are in poor health can be used as home medical centers as long as they spend money to load medical aids and supporting software. Although it cannot be cured, you can always monitor your physical condition. It is very easy to use according to Old Gu, pregnant women and young children. In case of an accident, it can automatically call pre-made contacts for help. Of course, things like fire alarm, anti-theft, disaster rescue, etc. are all optional modules. As long as you can think of small functions, this robot dog has almost all.

Anyway, the function of the robot dog is really convenient and practical. The annual sales volume of 5 million units of Longyuan is not blown out. It is really connected to circle Earth several times.

According to the information I downloaded from the spirit net network, when the contact person in our group came over, he should have brought twenty military version robot dogs. It is unreasonable to bring it but don’t use it. .

Only one of the few people over there remembered it when I asked. "By the way, it seems that a robot dog was sent in before, but it disappeared when I ran in. I don't know where it went. I can't receive a signal because of radiation interference outside. I don't know what the situation is now."

This one is more reliable. This is a uranium mine. The radiation intensity under the ground is very high. An ordinary person can lie down directly after being exposed to this environment for less than five minutes. The electromagnetic signal is strongly disturbed here, even if our heart's spirit net network is not received. Signal to the robot dog. Ordinarily, if the robot dog is here, the other party is a military device and should automatically connect to our network, but now there is no signal, which is obviously the result of radiation interference.

Since there is already a robot dog going down, then I am not too anxious. At the speed of the robot dog, people or relics that need to be rescued should be found before us. We only need to go over to receive the information and then process it.

From here, the Dao Foundation is not collapsed, the road is very smooth, but there are still a lot of rocks on the ground, but it is not enough to block the road. Considering that there is a lot of space in this place anyway, we simply activated the propellers and grabbed the eight people and flew in directly. Anyway, the height of the six-lane passageway was eight meters, and there was no pressure to fly.

I have to say that this passage is really deep enough. We flew forward along the passage for seven or eight kilometers before stopping. There were a lot of collapsed areas along the way, but most of them were only half collapsed. , The gap left was still very large. We didn’t even bother to slow down and flew directly over, but this place didn’t work anymore, because the first completely collapsed passage finally appeared here. We really couldn’t make it without clearing it up. .

Actually, it is completely collapsed, not really completely collapsed. At least there are some small gaps. Looking at the traces on it, you can clearly see that the twenty robot dogs have penetrated here, because There are plum blossom-shaped footprints on the ground, and there are steel bars that were bitten off by the robot dog's teeth near one of the holes, which should be the obstacle that the robot dog cleared when it moved forward.

We didn’t change the place either. We dug a big hole where the robot dog had drilled, and quickly got through the narrowest place. After this small hole, the remaining half was buried. It fell, but a large dome just fell down to prop up an inclined plane. There is a triangular channel underneath that is quite large. At least Inverite’s size can penetrate through it. Most people calculate riding a motorcycle. It should be able to pass, naturally it is not a problem for us.

After drilling through here, it is the passage again. This time we flew for two kilometers, and then we saw the third blocked passage, but it was not completely blocked here. There were several on the ground. The big hole can obviously be seen just by the robot dog. The ability of these robot dogs to make holes is not worse than that of real dogs, or should be said to be stronger. At least real dogs definitely cannot dig holes in the cement slab.

There is a lot of cement and rigid concrete on the ground of this place, which is obviously the roof of the cave collapsed from above, but now there is an obvious passage in it, and you can see that it was cleaned by a robot dog. . But this channel is really not big, we need to expand it a little bit in the past.

This time we didn’t wait to fully dig the passage, but digging until we were able to go by ourselves, and we went through it first, while Ivorite was left here to continue digging. It's too big, and the passage behind it will definitely be more difficult to walk. Waiting for him will delay our rescue.

After leaving Ivorite, we took the remaining eight guides and drilled through this newly dug narrow passage, and then found that the collapsed place is less than ten meters behind it is another section The collapse point, and the results of my electromagnetic induction scanning show that the thickness of the collapsed area is more than 50 meters, and it takes a very long time to dig past.

"Look, there must be other passages here." Without saying a word, I started to let everyone spread out to find the entrance, because there was no passage opening on the 50-meter-long landslide in front, indicating that the robot dog Did not go through, and there is no silhouette of the robot dog, which means that the robot dog must have found another way.

Sure enough, after I said, one of the guides immediately said: "No need to look for it. I know that there is an overhaul passage outside the main passage. Those robot dogs should pass over there. "

"Lead the way."

Following the guide, we found a small door on the edge of the collapsed passage. This door has been deformed very seriously, but at least we can get through . The passage behind is also half of the tower, but the triangle underneath can barely allow us to climb over.

Climbing forward along this narrow passage for less than fifty meters, we found that there is a cement board in front of the passage, but there is a round hole in the cement board. Such a regular circle is obviously a machine. Cut out by the dog. After drilling out from here, the passage behind it is a good passage without landslides, but there are many cracks on the wall, and it seems that the damage here is also quite serious.

This overhaul channel is not the same as the main channel. It seems to be going down all the time, and the slope is quite large. Fortunately, there is no blockage in the back.

After walking forward for a section of the road, we suddenly stopped because the passage in front was all submerged under water.

"Damn, what's the situation?"

"It should be that the groundwater was cut off when the collapse occurred, and then there was a leak." A guide said.

Another guide seemed to disagree with this guide’s opinion and said: "It should not be. The terrain here is actually very high and there should be no groundwater. The water supply pipe."

"Whatever it is, it seems that we need to go for a swim." I said, I jumped down first. Our team are all fully armed. Even the guides have simple power armor and helmets with oxygen circulation system. It’s no problem to make a temporary guest appearance in a diving suit. After all, the anti-radiation equipment itself must be waterproof, otherwise, if there is a leak, what about anti-radiation?

Actually, the underwater passage is not long. After a short walk, we found a closed iron gate, but weirdly did not find the robot dog. The military version of the robot dog is waterproof and has underwater propellers. Although the speed is not fast, it can indeed move in the water, but we did not find them here. This is obviously wrong, because I also found it before entering the water. Their footprints.

The gate that blocked the passage was deformed very badly, and it was closed. Even if the robot dog passed, it would be impossible to close the door again, so they definitely didn't go. The question is where they passed.

We simply checked and found a passage through which the robot dog can pass. This is a sturdy pipe, originally used to transport fresh air underground. The internal space is just right for the robot dog to pass through, but the problem is that we absolutely can't get through here.

"It seems we need to find a way to open this door."

"I'll do it." Xiaochun walked over slowly and ejected the laser cutter from his wrist, and then began to cut door. She didn't make a hole in the door, but simply cut off the deformed position, and then put the laser away and hit the door twice with her shoulder, and the door was opened, but there was still a channel filled with water behind, so she moved forward. Less than ten meters away from the underwater environment because of the elevation.

After returning to the air, my first reaction was not to observe the surrounding environment, but to find that the signal from the robot dog was vaguely received, but the signal was very unstable. Obviously we were very close to the robot dog.

"Quick, move forward, I feel the robot dog."

The people who just crawled out of the water followed me and started running madly before they took a break. Although the passage here is not wide, it hasn't collapsed, and it's still unobstructed.

Not long after running forward, we found a hole in the previous snorkel. The footprints on the ground showed that the robot dog should have returned to this passage from here, and I felt that the longer we were It's near, I can even receive a complete signal, but I still can't exchange effective information, but when I hit a broken wall blocking the way, the signal instantly became clear, because I found the robot dog Right in the main passage in front of me, but not twenty, but only eighteen are left, and two of them have fallen to one side of the ground with their heads in different places, and the remaining eighteen The platform formed a circle with a creature I had never seen before.

"My God...!"
