In fact, this sword array of gold coins is simply a water turbine. It generates centrifugal force through the rotation of the serrated knife wheel composed of flying swords and draws the water in the center of the sword array out of the sword array. In this process, vacuum pressure will be generated in the center of the sword array, forcing the external water flow to be forcibly sucked in from the opening of the sword array, thus forming a vortex water flow to suck all the external things into the sword array.

Although the strange fish move in the water very fast, as the sword formation is activated, the speed of the water flow begins to increase rapidly. We feel better behind the sword formation, but in front of the sword formation it completely turned into a huge black hole. The sea water in front is pouring into the sword formation wildly. The fish are driven by the water flow and gather towards the center of the sword formation. Although they instinctively feel the danger here and are desperately resisting this suction force, unfortunately their resistance is too small to resist this powerful suction force at all, and they are inevitably sucked into the sword formation.

The water flow in the sword formation will be carried by the rotating sword formation and accelerated to rotate inside the shock absorption, and the centrifugal force generated will force the water flow to leave the center of the sword formation and be thrown out towards the surroundings. Before leaving the sword formation, these water flows must pass through the outer wall of the sword formation composed of those flying swords. This is actually a sword wall composed of dense sword blades. Of course, the water can easily pass through, but those fish will not work. The fish that are rolled into the center of the sword formation will soon be thrown onto the outer wall of the sword formation along with the water flow, and then they will inevitably come into contact with the flying swords, and then be stirred into flesh mud by countless spiral blades before they can pass through the gaps of the sword formation.

Originally, when the sword formation was just completed, we thought this thing was quite spectacular, but after the fish were really stirred, we found that this thing should not be called spectacular, but should be disgusting. After the fish were stirred, it turned into a large dark red blood mixture, and then these things would be pushed back with the water flow, which means they were all blown to our side. We could not hide because other directions were not safe, so we could only let these disgusting fragments baptize us all.

Fortunately. Because underwater, we all isolated ourselves from the outside world. Those wearing armor closed their masks, while those without armor activated the protective masks. Anyway, no one was really soaked in the water, so although it felt a little disgusting, there was nothing that could not be accepted, as long as we didn't think about it in our hearts. It felt good, after all, we couldn't smell or feel that kind of touch here, so we didn't have to worry about this at all.

After shattering the strange fish, the gold coins did not immediately close their sword formation, but maintained it for a while, allowing the clear water to disperse all the pollutants around us before closing the sword formation. The flying swords automatically dispersed in the air and then flew back to the sword bag of the gold coins.

Put away the sword bag. The gold coins turned around and said to us, "It's done, let's continue to move forward?"

"Didn't you expect you to have some skills?" Zhenhong patted the gold coins on the shoulder and said.

"What a joke? Do I have some skills?" Jin Qin said back on purpose: "When did we go to the training ground to compete with each other? The lost Zui Baxian set up a table and let the dishes be as good as possible. How about it? Do you dare?"

Zhenhong smiled and said, "I am not like you. I have a rich husband. I rely on my skills to make a living, and I don't have as much spare money as you."

"Excuse me. If you don't dare, don't dare."

"Whoever says I dare not, okay, let's take a gamble."

"This is what you said yourself, everyone will testify." Jinzi pointed at the surroundings and said.

Bingbing smiled and said, "Then can we notary follow us and gain some benefits?"

"That's what you want to let go." Jin Jin said with a smile.

"The atmosphere here is still real and harmonious!" Masaga Matsumoto suddenly interrupted.

Christina smiled and said, "Why are you doing so serious with a good friend of the guild? Oh, by the way, does your new Black Dragon Association have no such relationship? Don't tell me that your work is like the army all day long!"

Matsumoto Masaga stopped talking when he heard this. Kakuda Ichiro next to him also remained silent for a while, because although Japan was not really like a large military camp, I have to say that it was really similar at some point.

Next, during our chat and fucking, everyone easily approached the bottom of the island in the middle of the lake. Without the interference of the strange fish, we can say that we were here without any obstacles. The next thing we need to do is find the entrance and then dive in. The underwater part of this Banshee House should have several entrances and exits, because although this water is a lake, it is not completely closed. If the surface ice layer can be broken, the boats in the lake can actually drive directly into the Arctic Ocean. And even if the deicing work is not carried out, there are several underground channels in this place that connect the oceans elsewhere, so if it is a submarine, it is actually very easy to enter and exit the lake.

Since this lake can connect to the sea area and allow submarines to be used unimpededly, the Banshee House will naturally not waste such conditions, so they set up a considerable 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 I took everyone here directly. What surprised me was that we actually found a small entrance and exit here specially for personnel. However, compared with the underwater facilities of our guild, the entrance to the Banshee House is much older.

Our guild has Atlantis technology, so there is waterproof barrier technology. With this thing, our underwater entrance can be made into a very simple straight-through structure. We thought that the waterproof barrier can effectively separate simple water from people who need to enter and exit, so we just need to go through it directly. However, the Russians obviously do not have similar technology, so they cannot use such a waterproof door, and can only use the most direct watertight room to block the entrance and exit. When someone needs to enter the inside of the base from the outside, they need to close the inner waterproof door first.

Then wait until the personnel enter the inside of the sealed cabin, then close the external hatch, then use high-pressure gas to drain the sea water in the cabin back to the water outside the cabin, then completely close the link between the cabin and the outside water and open the inner gate, and people can enter the base. Of course, just operate the reverse when coming out. Although this method is relatively simple to control, it takes up to two minutes to drain or inject water once, so this thing is actually quite slow. In comparison, our waterproof door is much more convenient.

Although we saw such a gate, we cannot use such a device to enter this time. Because this kind of thing will be more dynamic when it is started. Even if the other party does not have a dedicated personnel to guard the place, our situation may still be exposed. Besides, for the sake of safety of this kind of entrance and exit, we need someone to operate outside, so if you say that no one is staring at this thing, I will be beaten to death and will not believe it anyway.

If we can't go through the main gate, we can only consider some other evil ways. Fortunately, I have a lot of equipment. First, I fixed a waterproof door on a nearby rock, and then dig a hole backward from the center of the gate and enter the rock formation below the lake center island. Because the big hole dug out is a waterproof energy barrier. Therefore, when the passage is dug out, there will be no water from outside to pour in, so that the passage will not be filled with water. Although we can also move in a water-filled passage, the problem is that our purpose is to enter the Banshee House. If we do not guarantee that there is a waterless environment in the passage, then once we open up the other party's dungeon part, the water outside will quickly flow back into the other party's city. At that time, do you think that people don't know that we are here? Because of this situation, the passage must be dry.

After successfully entering the water environment to the dry environment, we began to remain absolutely quiet, and carefully followed the Trail Blazers along the way towards the dungeon, and this process did not take a few minutes in total. The Trail Blazers quickly approached the outer area of ​​the dungeon. The reason why they knew it had arrived was because the Trail Blazers hit a steel plate during the excavation process. The other party actually added all-steel armor outside the other city, which is quite strange. Because normally, it is easy to rust under the ground, so even if there is armor plate, it is rarely used as the exterior wall of the underground building. Even if metal armor is really needed to be used as the exterior wall, the underground building will usually be arranged with a layer of concrete-like substance outside to play the first isolation function. What must be equipped with a lime waterproof layer, and then there is a layer of stone and other things before metal armor can be considered.

However, the design of the Banshee House in front of me was so strange that they actually placed the steel plate directly on the outermost layer.

"Why do you bury the steel plate here?" Kakuda Ichiro asked in confusion when he looked at the complete steel plate on the section that had been opened in front of him. At the same time, he stretched out his finger to knock on the steel plate, but I pinched his hand before it even fell.

"What are you going to do?"

Kakuda Ichiro looked at me with a complicated expression, then returned to normal, and then said, "Of course, I'll take a look and see how thick this thing is."

"This thing cannot be touched."

"Why?" Kakuda Ichiro obviously didn't understand the reason why I said I couldn't touch it.

Matsumoto Masaga next to him walked up and gently pressed it on the steel plate with his hand, then whispered: "The real function of this thing is not defense, but early warning."

"At warning?" Kakuda Ichiro obviously didn't understand why there was such a strange function.

Masaga Matsumoto then explained: "These steel plates are equivalent to the collection end of the stethoscope placed by the doctor on you. The steel plate itself is similar to a vibrating membrane, and there are no other defensive materials behind this steel plate. If I guess correctly, this steel plate should be hollow after it. There are probably many support columns behind the steel plate. I deliberately leave a sound collector to expand the vibration, so that they only need to arrange some sound collectors in these places to know whether the outer armor has been invaded. Once we break through this steel plate, we must make noise, and this is equivalent to ringing the alarm bell for the enemy."

"Will we not be able to move at all?" Kakuda Ichiro said: "As long as we destroy this steel plate, we will make noise. Wouldn't it be exposed at that time?"

"No, no, no, we don't need to be so careful. All we have to do is not make any noise, not that we can't touch this layer of steel plate at all."

Kakuda Ichiro was not a fool either. He thought for a while and understood it, and then asked in a low voice: "Who can you do this layer of things silently?"

"I'll do this." Christina walked over directly, then stretched out a finger and pointed it on the steel plate. The position on the steel plate at the point of Christina immediately began to rise, and the steel plate also began to soften and dissolve quickly, feeling as if Christina's finger was an electric soldering iron, while the steel plates were snow blocks.

Before the steel plate melted through, I started the team channel and said: "Now, everyone's communication uses the team channel. Don't speak directly. Try not to make any sound in the cavity behind it to prevent being defensively from being attacked by the enemy."

Everyone answered what I meant on the Squad channel, and then everyone waited for Christina to clear the way there.

It didn't take long to melt the steel plate. The key is to create a passage that allows us to drill through, which is a little waste. Originally, Christina still had many ways to penetrate this steel plate. Even if it was specified to use corrosion magic, there were still many ways. But the key problem is that ordinary corrosive spells actually make some sounds. Because the corrosion speed is too fast. A single use of strong acid magic on the metal surface will make a chirp sound, and this sound is obviously very easy to detect in such a quiet place.

For safety, Christina finally had to choose a relatively quiet magic, but unfortunately the speed of this thing is really not satisfactory.

After finally opening a big hole that was enough for us to pass, we finally confirmed our previous guess. There was indeed a cavity behind the steel plate, but the structure was much more complicated than we thought.

In fact, after opening the steel plate, we see not a huge underground space, but two conical rooms on the left and right. The hole opened by Christina was about one-third of the left and right, and there was a metal dividing line. There was a space on both sides of the dividing line. This dividing line was a regular hexagon facing us. Then, as the space extended to the distance, the hexagon began to gradually shrink and finally gathered into a point, forming a flat vertebral space.

Although the overall look is not easy to understand, if you put this room alone, you can find that its shape is actually very similar to the simple amplifier rolled out of iron. The structure of this thing itself is not complicated, but so many of this structures are attached to the gap between the city and the underground structure outside the city, the project volume is quite amazing.

Although I was not a building student, after seeing the structure of these two small rooms, I immediately guessed why Banshee House designed such a structure.

First of all, these rooms do have similar functions as recommended speakers, but they are not loudspeakers, but sound collectors. No matter when you roll any object with a certain degree of hardness into a trumpet shape and aim the small mouth at your ears, this thing can increase your hearing range to a certain extent. The room in front of you is actually an amplified sound collector. It relies on its own resonance structure to collect sound waves, then gather it to the bottom of the conical structure, and then directly connect it to the control center through a small tube.

One of the advantages of this design is that it can increase the sense of sound wave inscription. After resonance amplification, even small sounds can be heard. The second advantage is that it can be positioned. Originally, we thought that the space behind the steel plate should be an integral communication structure, so that the other party can only hear whether someone has entered the area behind the steel plate, but cannot determine the source of the sound. But now it is different. These individual conical rooms will only transmit the sound at their location, while the sound from other locations cannot be heard. In this way, as long as the other party numberes the sound collector pipeline when building these things, they can easily find the specific source of the sound, thereby accurately positioning 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 fully passive. It does not require additional equipment, consumes energy, and is not disturbed. More importantly, it is difficult to detect.

It can be said that this kind of thing is definitely a nightmare for sneak attackers, because almost no one can pass through this place completely silently, of course, unless you, like us, can guess in advance that the place is behind the monitoring range, thereby controlling the noise in advance.

The second function of these conical small rooms is reinforcement.

Because of the stability of the vertebral structure itself, these small rooms next to each other can actually serve as supporting beams. And because each room has the same shape, they can allocate pressure by structural strength. That is to say, the firmness of this thing exceeds its own material strength because it can disperse pressure to a large extent. On the surface, it seems that it has been under pressure exceeding the material limit. In fact, for the internal materials, the pressure at each position has not reached the limit.

There is a third advantage of this structure, which is to completely isolate the inner and outer spaces. Because of the existence of these small enclosed rooms, the outer wall of this dungeon and the outer structure we had penetrated before are filled with many fixed particle structures. This structure plays a role like a foam, which can completely insulate heat, sound and isolation of various radiation.

This excellent design shows that the Russians' engineering and technical level is quite advanced. At least the dungeon structure of this Banshee House is quite exaggerated. Although we have safely broken through a layer of steel plate, we were even more amazed after seeing the internal structure.

After Christina melted the steel plate in front of us, she turned around and added a light aura technique to each of us, which could prevent us from making a lot of footsteps due to our own weight. Christina herself quickly moved to the tip of the vertebral structure and began to continue melting the steel plate in this place.

After carefully opening a big hole in one of the vertebrae bodies, we entered the vertebrae room in the second floor structure behind it, but there is no characteristic of the sound collector here. Of course, we still need to keep quiet, because the hole we opened before is actually connected to the rooms outside with the sound collector function.

Arriving at the bottom of the vertebral room here, Christina removed the steel plate in front with her hands, then closed her eyes and sensed it before turning to me and said in the team channel: "President, there may be some trouble here."

"What's wrong?" I leaned over and asked, and Kakuda Ichiro and Matsumoto Masao also quickly surrounded him.

Christina pointed directly at the wall and said, "Let go of your magical sense to feel the situation behind this wall."

After hearing Christina's words, we all quickly sensed the situation on the wall. As a result, what we felt surprised us because there were dense magical lines behind the wall.

The so-called magical lines are actually things like wires. Of course, I say that the same refers to the similar properties. In fact, there is still a big difference between magical lines and wires. The things they transmit are different, and the materials themselves are different. What they are the same is that they are all a kind of wire, and they are the medium for transmitting energy. The difference is just that the properties of the energy transmitted are different.

Normally, there must be a formation map master for guilds that can make magic lines. The complexity of the magic lines depends on the level of the formation map master. The magic line networks that our guilds currently only have basically no difference from large-scale integrated circuits, and their function is to concentrate more magic on a smaller area with higher output intensity.

However, the magic lines behind this wall are not used to do this. In fact, the magic lines on this wall are actually alarms. They are buried in the wall. If you cannot sense the flow of magic power, you will directly destroy the wall and break these magic lines. Then, as soon as the magic lines are broken, the other party will know that someone has come in. Moreover, because this magic line itself calls the alarm through the continuous transmission of energy, even energy bodies like Ghost cannot bypass this line, because once the energy bodies pass through this line, there will be interference phenomenon, and the reaction of this phenomenon is very obvious, at least enough to let the other party know that something has come in.

Some people may say that since we know the existence of magic lines, isn't it okay? Yes, if it's a simple magic line and knows their existence, don't destroy it, there is no big problem. But the problem now is that the structure of these things is too complicated, and various lines are constantly using messy linking methods to form a three-dimensional maze-like structure, which makes us unable to determine the specific direction and magic strength of the lines. Therefore, even if we discover these lines in advance, we cannot simply rely on inserting magic signals to interfere with the operation of these things, because we don't know how to insert signals at all. After all, it is not a good idea to connect randomly when the superior and subordinate relationships between the lines are not clear.

Faced with such complex structure, even magic masters like Christina frowned, while players like Kakuda Ichiro and Makoto were very relaxed. Anyway, they couldn't understand it, and it would be the same no matter how complicated it was.

Although Kakuda Ichiro and Mahong couldn't understand it, there were still many people here who could understand it. Because we could understand it, we frowned and thought together. After all, if we wanted to go over, we had to destroy this wall. If we wanted to destroy this wall and didn't want to be discovered, we could only find a way to jump to these connection lines. However, before jumping these connection lines, we need to find their transmission structure, that is, we know what the circuit diagram is, but the complex three-dimensional structure of this thing is definitely not so simple to analyze clearly. As long as any line is wrong in the order, an alarm will be triggered.

"This thing is too complicated!" Masaga Masao Masao said.

Chihuo Longji also rubbed her eyes and said, "No, her eyes are all blurred. I can't touch this thing!"

Sakura Yu Shen Hikari and Azuki Huo also shook their heads and retreated aside. They were completely unable to start with this thing, just like everyone else. The route is too complicated. If you rely on manual analysis, you need to do written calculations in draft paper, otherwise it will be difficult to figure out the specific direction of the route map. What's more serious is that the structure of these things is too dense, and there are no signs on it. So if you have a little bit of attention, you will not be able to figure out where you were looking at before. Once this happens, it means that your previous calculations are in vain.

"What a joke? Isn't this kind of thing done by humans?" Jin Qin rubbed his eyes and squatted down after holding on for a few minutes, but he really couldn't analyze it.

Compared to them, I am a little better. Because I am a dragon clan and there is an electronic chip in my brain, I can virtually image this circuit diagram in my brain like a computer. Then, using the simplest knowledge similar to that in junior high school physics, I can directly simplify this circuit diagram into a standard circuit diagram, and then just find the upper and lower nodes and restore it to the corresponding position on the original circuit diagram.

This kind of work actually requires a person to synchronize a lot of information. In this process, there is no way to rely on external devices to record the previous calculations, which leads to people who often forget the previous calculations, and the result is that they repeatedly calculate and cannot get the result.

Obviously, the people who designed this thing deliberately designed such a structure. Their purpose is to make people dizzy, so that you cannot discover the structure of this thing and you will be unable to crack it.

After five minutes, I found all the security nodes on this thing, so I directly said to Christina, who was still calculating: "Don't forget it, I have found the security line."

"Tell me quickly. Where is my position." Christina did not ask me in surprise as ordinary people in the first place. On the one hand, it was because of her trust in me, and on the other hand, it was because she was smart enough that she knew that even if she calculated this kind of thing, she would forget it if she was not careful. So she didn't dare to interrupt my thinking, but asked me to tell her the position directly.

"You get out of the way. I'm too slow to cooperate and let my magic pet go."

Christina let her go without hesitation when she heard my words, and Ling appeared in front of us at the same time. Everyone present, including Kakuda Ichiro, knew Ling. After all, this is the most popular magic pet I played.

Because there is a spiritual link, Ling and I do not need language when communicating, and can directly convey the past of thinking, so I can send all the calculation results in an instant without converting them into language patterns to describe this picture.

Ling's magic control power is definitely not worse than Christina, so after getting the detailed drawings I calculated, I immediately took a lightning strike to draw a hanging magic array in the air. This void drawing ability is the ability of a top magician, and ordinary mages can't play with it at all. After drawing the magic array directly in the air, Ling quickly clicked it a few times, fixed the magic probe on this magic array, and then connected all the magic points. Of course, these links are not simply one-to-one, nor are they all connected, but are connected based on the circuit diagram I calculated before, because magic lines also have parallel and series connections, and compared with the circuit diagram, magic lines have another connection type called reverse connection, which is a more complex link type. Therefore, the specific jumper needs to be connected according to my drawings.

Ling was very fast, and it took only a few seconds to complete the linking work of all the connecting lines. After that, she added a black light ball to the center of the hanging magic array. The frontmost position of the light ball was on the same plane as the tip of the magic probes, which means that when the magic array moves to the magic line on the wall as a whole, the moment the probe pierces the key node in the line, the black magic ball in the center will also simultaneously destroy the part of the line that was jumped in the center.

The reason for this arrangement is to avoid the other party's detection equipment being more intimate, and it can be found that there are additional lines in parallel in the line. After all, some magic arrays in our guild have similar functions, so it cannot be ruled out that the Russians have similar technologies.

After putting all these things in place, Ling decisively relaxed behind the magic circle. The magic circle immediately flew forward and instantly covered the wall. At the same time, the center of the wall was also swallowed by the black magic light ball.

"Is this successful or not?" Looking at the current situation, Kakuda Ichiro asked with some uncertainty.

Chihuo Longji said beside him: "I don't understand it at all like you."

Christina explained at this time: "It should be successful, because the magic line is still running and there is no change. If the alarm is activated just now, the magic power flow in the line here will change a little more or less. Of course, it is not ruled out that the structure of this magic array is too large, resulting in the possibility that it can automatically filter out clutter."

Kakuda Ichiro obviously couldn't understand what Christina was saying, but it didn't prevent him from figuring out that we could pass.

After roughly confirming that this thing should not be a big problem, we began to carefully drill through the hole in the wall.
To be continued...
