The armed robots on the lower floors of the office area did not have any interception effect and were quickly killed. The remaining layers were surprisingly empty and no one was arranged to defend. Then we smoothly advanced to the top floor of the office area.

This place is the highest point of the office area, but it is actually no different from the lower floors. The room is just divided into compartments, unlike the large passage below. However, the better place here is that the room here is very clean and tidy, because it has not been damaged, so the power is working normally. Of course, this also means that the monitors can clearly see our status.

I originally thought that the other party would be intercepted on the last floor of the office area above, but the other party's arrangement was slightly different from what I imagined, because we did not encounter any resistance here, so we directly found the stairs leaving the office area.

According to the standard building configuration in the United States, there is a commercial activity area at the bottom, an office area in the middle, and a residential area at the top. After we pass through the office area, we enter the residential area.

The residential area and office area are different. The structure here looks a bit like the structure of a hotel, but it is not as dense as the room next to each room in a hotel. This type of residence on the top floor of a building is usually a villa with a large apartment. Although each household is located inside the building, its internal space is actually not much different from a separate villa. In addition, because each household is a duplex structure, there is only one aisle on every two floors of the aisle, but this has little impact on us, because we did not intend to enter the corridor at all.

The buildings in this place are designed according to regular buildings, and the buildings are not mazes. Of course, you don’t need to go through every passage below to the upper floor. You just need to walk up the stairwell. As for the elevator... that’s fine. We are doing irregular exercises. If we go in, we can just throw a bunch of cluster grenades into the elevator shaft from the upper floor and we can give in directly. Although cluster grenades are useless to us, it is definitely no problem to blow up the elevator. This place is already fifty stories high below. If you fall from this height, even if you don’t use your wings to slow down, even we are in a certain danger. However, our wings cannot be opened in the elevator, so the elevator is very dangerous for us.

After entering the residential area, we did not enter the first floor, and then we began to rush up the stairwell directly. According to the fire map we got before, from here, we were all the way up the passage exit of this scene. As long as we passed, it means we passed another level.

I thought the process would be smoother, but soon we understood why the other party didn't leave anyone here to stay. The reason was right in front of us.

This was a pile of steel bars and rubble that was crossing us. These guys actually blew up the stairs in the stairwell. All the stairs on the upper floor fell and stuck on this floor, forming a pile of three-story building waste. It would be very difficult to pass through here.

In fact, the other party is a bit sloppy in doing this, because it is impossible for this kind of stairs to be blown up separately in a real building, unless you blow up the entire building together. Because when you are piled up in a normal building, there is a whole between the stair steps and the wall of the stair shaft outside. The two are combined with steel and concrete, which is not so easy to get down. However, this building is a simulation training base, and it is a space dug underground. In other words, this vertical stair shaft is actually a vertical well dug in the mountain body. Then it is artificially drilled holes in the wall, then stuffed steel bars to support, lay barbed wire on the support, and then plastered on the support. Then, the steps are shaped with cement.

This construction method is obviously different from the construction method of a regular building. Because the steps and walls are not a whole, but are fixed by only a small amount of steel bars, just blowing up these support points can cause the entire stairs to collapse, and it is not so easy to blow down the stairs in ordinary buildings.

No matter what, the stairwell in front of us is useless, so we can only go on another road now. If it is a normal building, I think I can climb up from the outside or simply fly up, but this "building" does not have the so-called "outside". So this place can only be found from the inside of the building.

"Return and let's see if we can penetrate the ceiling."

We quickly retreated into the corridor next to us. There were only eight doors in this not-so-long corridor, representing eight houses. We didn’t need to buy a house. Of course, there was no need to be picky and picking. We went up and kicked the nearest door open, and then entered the interior of the room.

After entering the room, we did not go deeper. We jumped directly from the split-level living room to the aisle on the upper floor, and then used electromagnetic induction to sense the thickness of the ceiling above our heads, and then jumped up and punched it on the ceiling.

In fact, it would have been faster to shoot with a gun, but our weapons were all equipped with pigment bullets, so we couldn't expect this thing to damage the floor, so we had to change it to a fist. Fortunately, this hardness did not have any effect on us. A few punches pierced a big hole in the ceiling, and then cut the steel bars inside with a dagger and bent it. Soon we made a big hole that people could drill through.

After making the big hole, Ye Yue was the first to come to the entrance of the hole, and then her tail was slightly raised, and her upper body gradually rose through the big hole and entered the room on the upper floor. After all the upper body passed, her tail bent to the edge outside the gap and found a support point, and then the lower body moved up directly.

After Yeyue went up, he did not completely remove his body, but left the last small section of his tail below. I walked over and patted her tail, and Yeyue immediately pulled me up with a roll of his tail.

After I got up, Yeyue moved to the corridor on the upper floor with me, and then started digging holes again, and the people below were climbing up one by one.

Of course, the ceiling on the upper floor is of the same material, so a new big hole was quickly opened. After we opened the hole here, Ye Yue still stepped forward, while the others below were still on the lower floors and they didn't fully come up. After all, there was only one hole at the entrance, so we needed to queue up, and the speed of opening the hole was obviously much faster than passing.

After I went up to the upper floor again, Yeyue and I separated. Let Yeyue continue to dig holes upwards. I went out to take a look at the building.

The gap above can be seen at the top of the stairwell gate on this floor, but there are still some rubbles across it. I think it is better to dig holes from the original place.

When I returned to the room, Yeyue had already broken through the passage on the upper floor and entered the upper floor. Ling Gang came up from below. Now he was waiting for Yeyue to pull her up at the hole below Yeyue.

When I walked over, Ling had been pulled up by Ye Yue. Jingjing had just climbed up at the entrance of the cave below. But at this moment, we suddenly heard a loud bang from the floor above. The entrance of Ye Yue and the others had just stepped up instantly spewed out of the cave. Jingjing and I instinctively protected our faces with our hands and took two steps back. Fortunately, the flames were mainly upward, and not many came down from the entrance of the cave.

Although it was not burned by the flames, the explosion meant that Ye Yue and the others were ambushed. I rushed to the entrance of the cave without saying a word, and without thinking, I jumped up on the ground. However, as soon as I came out of the entrance of the cave, I sensed something rushing towards me.

"Damn it!" It was not until I entered this floor that I understood why we were sneak attacked. Because there were a large number of special particles floating in the room on this floor. This particle is a common particle in the laboratory, which is mainly caused by static electricity generated by high-voltage electrical appliances. The particle is not stable and will appear after being stimulated by high-voltage current. Then, as long as the electric field disappears, it will automatically gradually merge into the air to form common air magazines, without any residue.

Because this particle itself is harmless and has no use, no one usually cares about this kind of thing. However, in fact, we know that this thing is not really useless. It actually has a very special ability, which is to reduce the resistance of air.

The resistance value of air is very large. This is why you will not be electrocuted as long as you don’t touch the wire, because the air resistance is very high and will not form current between you and the wire. However, the existence of this particle can carry electronic movement, so it will reduce the resistance of the air. However, the degree of reduction is very small, so there is generally no need to take special protective measures for this phenomenon.

However, it was not long ago that the effect of this particle in reducing the air resistivity can produce another effect of electromagnetic wave absorption.

The resistance of the air after the resistivity decreases is still very high, and it will not become a conductive substance. However, this air containing a large number of these particles will absorb a large amount of electromagnetic waves, causing the radio to transmit signals in this area to decrease. Radar waves will also be absorbed.

If this particle is not unstable and cannot be solidified on the metal surface, this is actually a very good radar stealth material. However, this thing is unstable. And it is free particles that cannot be constrained, so naturally there is no way to allow the aircraft to be protected by this thing. However, although there is no way to use this thing to shield the radar on the aircraft in the air, this does not mean that it is not possible in confined space.

The method the other party used was to fill the room with such particles, so the room became an electromagnetic black hole. Our electromagnetic induction ability was completely invalid here, so there was no sense of the ambush here. Otherwise, we should be able to find these talents through the floor.

In fact, there is another reason why these people succeeded, that is, the dust in the air and the power armor on their bodies.

Our dragon clan is not only powerful in electromagnetic induction. In fact, our five senses are much stronger than humans, so we can usually find the enemy's hiding places in some inconspicuous places. However, because they had blown up the stairs in the stairwell before, there was a lot of cement ash in the air. Moreover, we dug holes there just now and penetrated the floor slabs, it would also cause a lot of dust. Therefore, we had switched the helmet mask to the internal circulation mode in advance. In this mode, our power armor is similar to the space suit and will not exchange gas with the outside world, so we naturally did not smell the scent of the ambushed personnel on the above layer. Otherwise, with our noses, we would never be able to smell the smell of these people.

In addition, sound is also a very sensitive place for us. Not to mention those louder sounds, we can accurately hear the sound of people's breathing and heartbeat. Therefore, unless the environment itself is noisy, it is difficult for people hiding in the dark to avoid our pursuit, because their heartbeat is the best beacon. The more panic, the more rapid the breathing and the accelerated heartbeat, the more we will discover it.

However, these people here are elite, and the limited personnel are all wearing power armor, and the rest are all armed robots. These power armor and armed robots will not produce any sound as long as they do not move in silent mode. As for the heartbeat of the soldiers, we cannot hear the heartbeat of the soldiers. No matter how good our ears are, we must have a sound to hear it! Their power armor is so thick, and through multiple layers of composite materials, we naturally cannot hear the sound of the human heart beating alone.

Because of these conditions, we were finally ambushed by the other party this time. Moreover, these guys had a really good idea. They actually thought of blowing up the steps and forcing us to dig holes. And they seemed to be fine. Because we digging up the holes, the team would definitely turn into a long snake formation. They didn't have to face all of us at the same time, and just dealt with one or two targets at a time. This is really a good idea.

In fact, not only the above floor is ambushed, but also the below floors. Just as I jumped up, there were two explosions of different sizes below. Obviously, there were people in the lower floors. I guess the other party had ambushed in some rooms inside the corridor, because we wanted to save trouble and would definitely not go in, so they just had to find a room deep in the corridor to spray particles to block electromagnetic signals. The rest was to wait for us to fall into the trap and then fight out to take revenge.
