Chapter 2897 (1/2)
In fact, the sword array of gold coins is a water turbine, which generates centrifugal force through the rotation of serrated cutter wheel formed by flying swords, and draws the water in the center of the array to the outside of the array. In this process, a vacuum pressure will be generated in the center of the sword array, forcing the external water to be forced to be sucked in from the opening of the sword array, thus forming a vortex like flow, which sucks all the external things into the sword array.
Although the speed of those strange fish in the water is very fast, with the full power of the sword array, the speed of the water flow also starts to increase rapidly. We feel better behind the sword array, but the front of the sword array is completely turned into a huge black hole. The sea water in front of the array is rushing into the interior of the sword array crazily. Those fish groups are driven by the current and converge towards the center of the array Come on, although they instinctively feel the danger here, they are struggling to resist the suction, but unfortunately, their resistance force is too small to resist the strong suction, and eventually they are inevitably sucked into the sword array.
The water flow in the sword array will be carried by the rotating sword array to accelerate and rotate inside the shock absorption. The centrifugal force will force the water flow to leave the center point of the sword array and be thrown out towards the surrounding area. Before leaving the sword array, the water flow must pass through the outer wall of the sword array formed by flying swords. This is actually one of the dense sword blades Dao Dao Dao wall, of course, the water can easily pass through, but the fish can't. The fish caught in the center of the sword array will soon be thrown onto the outer wall of the array along with the current. Then they will inevitably contact those flying swords. Then they will be stirred into flesh and mud by countless whirling blades before they can pass through the cracks of the array.
Originally, when the sword array was just completed, we thought it was quite spectacular, but after the fish were really stirred in, we found that it should not be called spectacular, but should be disgusting. After the fish were smashed, they turned into a large dark red mixture of blood and water, and then these things would be pushed backward along with the current, that is, all of them were blown to our side, but we couldn't hide because it was not safe in other directions, so we could only let these disgusting fragments baptize us all.
Fortunately, we are all under water. Those wearing armor have closed their masks, while those without armor have activated the protective covers. Anyway, no one is really immersed in the water, so although it feels a little disgusting, there is nothing unacceptable. As long as you don't think about it, it feels good in fact. After all, there is neither smell nor touch here, so there is no need to worry about this.
After smashing those strange fish, the gold coin didn't immediately close the sword array, but multidimensional held it for a while and let the clear water disperse the pollutants around us before closing the sword array. Those flying swords spread out in the air automatically, and then they flew back to the gold coin bag.
After collecting the sword bag, the gold coin turned to us and said, ”it's done. Let's move on?”
”I didn't think you had any skills.” True red clapped the gold on the shoulder and said.
”Are you kidding? Is that something I can do? ” The gold coin jokingly retorted: ”have the ability, which time we two go to the training ground to have a discussion, the lost drunk eight immortals set up a table, any dish.”. What about? Dare you? ”
Zhenhong said with a smile: ”I am not like you, I have a rich husband, but I rely on my ability to eat, not so much free money as you.”
”Excuse, dare not.”
”Whoever says I dare not, well, we'll bet.”
”That's what you said, everybody testify.” The gold coin pointed around and said.
Bing Bing said with a smile: ”then we notaries can follow with some light?”
”That's right.” The gold coin said with a smile.
”The atmosphere here is really harmonious.” Matsumoto suddenly cut in a sentence.
Christina said with a smile, ”a good friend of the guild, what are you doing so seriously? Oh, by the way, don't you have such a relationship with the new black dragon club? Don't tell me what you do all day long is like the army
Matsumoto was not talking when he heard this, and Ichiro Kawabata was also silent for a moment, because although the Japanese side is not really like a large military camp, it has to be said that sometimes it is really a little similar.
Next, in our chat and fart, we easily got to the bottom of the lake island. Without the interference of those strange fish, we can say that there is no obstacle to get here. The next thing you need to do is to find the entrance and sneak in. There should be several entrances and exits for the underwater part of the Banshee house, because although the water area is a lake, it is not completely closed. If you can break through the surface ice, ships in this lake can actually sail directly into the Arctic Ocean. Moreover, even if there is no de icing work, there are several underground waterways connecting the sea, so it is very easy to get in and out of the lake if it is a submarine.
Since this lake can connect with the sea area, so that submarines can be used without obstruction, the Banshee house will not waste such conditions, so they set up a quite large submarine base here, and the entrance is underwater.When I came last time, I didn't go to the submarine base, but I saw this place at that time. So this time, I took you here directly. To my surprise, we found a small entrance and exit for personnel. However, compared with the underwater facilities of our guild, this entrance of Banshee house is much older.
Because of Atlantis technology, our guild has waterproof barrier technology. With this thing, our underwater entrances can be made into a very simple straight through structure, thinking that the waterproof barrier can effectively separate the simple water from the people who need to enter and exit, so that we can directly cross it. But the Russians obviously don't have similar technology, so they can't use such waterproof doors, they can only use the most direct watertight chamber to block the entrance and exit. When someone needs to enter the interior of the base from the outside, it is necessary to close the inner waterproof door first, and then close the outer hatch after the personnel enter the sealed cabin. Then, use high-pressure gas to drain the seawater in the cabin back to the water outside the cabin. After that, close the connection between the cabin and the external water and open the inner gate, then people can enter the base. When you come out, of course, you just need to reverse the operation. Although this method is relatively simple to control, it takes as long as two minutes to drain or inject water once in and out, so it is actually quite slow. By contrast, our waterproof door is much more convenient.
Although we see such a gate, we can't use such a device to enter this time, because the movement will be relatively large when this kind of thing starts up. Even if the other party does not have special personnel to guard here, we may still expose our situation. Besides, for the sake of safety, the entrances and exits need to be operated by someone outside. Therefore, if you want to say that no one is staring at me, I'm not sure.
If we can't go to the front door, we can only consider some other heresy. Fortunately, I have a lot of equipment in my hand. First, I fixed a waterproof door on a nearby rock. Then, from the center of the gate, I dug a hole backward to enter the rock layer below the island in the middle of the lake. Because the outside of the big hole is a waterproof energy barrier, when the passage is dug out, there will be no outside water pouring in, which can ensure that the channel will not be filled with water. Although we can also advance in the water filled channel, the problem is that our goal is to enter the Banshee's house. If we do not guarantee that there is no water in the passage, once we get through the underground part of each other, the water outside will quickly pour into the other's city. At that time, do you think people don't know that we are here? Because of this situation, it is necessary to ensure that the channel is dry.
After successfully entering the dry environment from the water environment, we began to maintain absolute silence, following the pioneers carefully along the way towards the dungeon, and the process took no more than a few minutes. The trailblazers approached the outskirts of the dungeon very quickly. The reason why they knew that they had arrived was because they hit a steel plate in the process of digging. It is quite strange that all steel armor has been added outside the other side's city. Normally, metal products used under the ground are easy to rust. Therefore, even if there are armor plates, they are rarely used as exterior walls of underground buildings. Even if we really want to use metal armor to make the exterior wall, the underground building usually has a layer of material similar to concrete to provide the first isolation. After that, it must be equipped with a lime waterproof layer, and then there must be a layer of stone and other things before metal armor can be considered.
However, the design of the Banshee house is so strange that they put the steel plate directly on the outer layer.
”Why are steel plates buried here?” Looking at the intact steel plate on the section which has been stripped away in front of him, Yoshida asked in doubt. At the same time, he also stretched out his finger to knock on the steel plate. As a result, his hand was pinched by me before he fell down.
”What are you going to do?”
Yoshida looked at me with a complex expression, then returned to normal, and then said, ”of course, take a look, see how thick this thing is.”
”It can't be touched.”
”Why?” Yoshida obviously didn't understand why I couldn't touch it.
Matsumoto next to him came up and gently pressed his hand on the steel plate, then whispered: ”the real function of this thing is not defense, but early warning.”
”Early warning?” Yoshida obviously does not understand why there is such a strange function.
Matsumoto later explained: ”these plates are the collection end of the stethoscope that the doctor puts on you. The steel plate itself is similar to the vibrating membrane, and there is no other defensive material behind this plate. If I'm right, the steel should be hollow behind it. There are probably a lot of supporting pillars behind the steel plate, and the echo is deliberately set aside to amplify the vibration, so that they only need to place some sound collectors in these places to know whether the outer armor has been invaded. Once we break through this layer of steel plate, we must make some noise, and this is tantamount to ringing the alarm bell for the enemy. ”
”So we can't move at all?” ”As long as we destroy the steel plate, it will make a noise, and then it will be exposed.””No, no, no, we don't need to be so careful. What we have to do is not make any noise. It's not that we can't touch the steel plate at all.”
Kada Ichiro is not a fool. After thinking about it, he understood it and then asked in a low voice, ”who has the way to open this layer of things silently?”
”I'll take this one.” Christina went straight over, and then put a finger on the steel plate, and the spot on Christina's point of the steel plate started to take up a lot of white foam. At the same time, the steel plate began to soften and dissolve quickly. It felt like Christina's finger was an electric iron, and those steel plates were snow pieces.
Before the steel plate was melted through, I started the team channel and said, ”now we all use the team channel for communication. We are not allowed to speak directly. In this back cavity, we should try not to make a sound to prevent being defended by the enemy. ”
Everyone answered me on the team channel, and then everyone waited for Christina to get out there.
It doesn't take long to melt through that steel plate. The key is to make a passage that we can get through. It takes a little time. Originally, Christina had many ways to get through the steel plate. Even if she was designated to use corrosion magic, there were still many ways. But the key problem is that the general corrosive magic actually makes some sound. Because the corrosion rate is too fast, such as strong acid magic on the surface of metal will make a wheezing sound, which is obviously very easy to detect in such a quiet place.
For the sake of safety, Christina can only choose a relatively quiet magic, but the speed of this thing is really not flattering.
It was easy to make a big hole enough for us to go through. After we finally confirmed our previous conjecture, there was a cavity behind the steel plate, but the structure was much more complicated than we thought.
In fact, when we opened the steel plate, we saw not a huge underground space, but two conical rooms on the left and right. About a third to the left of the opening that Christina opened, there was a metal dividing line, with a space on either side. The side of the space facing us is a regular hexagon, and as it extends far away, the hexagon begins to shrink and eventually converge into a point, forming a flat vertebral space.
Although the overall look is not very easy to understand, but if you put this room alone, you can find that its shape is very similar to the simple loudspeaker rolled out of iron sheet. The structure of this thing itself is not complicated, but so many of these structures are attached to the space between the city and the underground structure outside the city, which is quite amazing.
Although I didn't study architecture, after seeing the structure of these two small rooms, I immediately guessed why the Banshee house designed such a structure.
First of all, these rooms do have the same function as the proposed loudspeaker, but it's not a loudspeaker, it's a concentrator. No matter if you roll anything with a certain hardness into a trumpet shape and aim your mouth at your ears, it can increase your hearing range to a certain extent. The room in front of you is actually an enlarged sound collector. It collects sound waves by its own resonant structure, and then gathers them to the bottom of the conical structure, and then connects it directly to the control center through a small tube.
One of the advantages of this design is that it can increase the impression of sound waves. After resonance amplification, even small sounds can be heard. The second benefit is more obvious, that is, it can be positioned. Originally, we thought that the space behind the steel plate should be a whole connected structure. In this way, the other party could only hear whether someone broke into the area behind the steel plate, but could not determine the source of the sound. But now it's different. These individual cone-shaped rooms will only transmit the sound from their own location, and the sound from other places will not be heard. In this way, as long as the other party in the construction of these things to the sound collector pipe number, you can easily find the specific source of sound, so as to accurately locate the enemy's invasion point.
This design can be said to be quite clever, and the biggest advantage of this thing is that it is completely passive, does not need additional equipment, does not consume energy, will not be disturbed, and more importantly, it is difficult to be found.
