The skill that King Chuang wanted to demonstrate to me was actually very simple, because this skill is called - diving.

That's right, it was like a submarine. Just as the order from the King of Breaking was completed, the super mothership named after me, the Purple Ri, behind us, began to slowly advance and sink. Almost all of the people standing on the deck were stunned. In fact, not only did I not know that the new warship had this ability, but even Kris Dena did not know that our warship had this ability. The Navy's technology was responsible for special personnel. If we had not landed in the Navy's warship, we would not have known these things at all, so we could have said that we had nothing to do with this.

"Are you wrong?" As the Zi Ri slowly sinks, Kris Dina, who is standing beside me, was almost glaring her eyes. Such a large warship is actually a submarine, and it is impossible for normal people to understand this kind of thing. You should know that submarines are not actually built in large quantities, but do not need to be too large. In addition to a small amount of combat capabilities, giant submarines will also produce more side effects. Therefore, after the size increases, the practical value of submarines is actually not increased, but reduced. In addition to a few submarines that are specially customized for special needs, under normal circumstances, the tonnage of submarines is best kept below half of the main combat ships in service. Because such submarines can play their strengths.

We have never thought about the fact that the Purple Ri can dive before, but based on my previous words and the intention of the King of Chuang demonstrated this ability, we can confirm that it is definitely not just the Purple Ri ship. In other words, the entire First Cruiser Fleet here is a submersible warship that can dive.

When I recovered from the amazing scene of the Purple Ri diving, the Purple Ri in front of me had basically entered the underwater navigation state. What we can see at present is that the Purple Ri's sighting equipment and some antennas are still above sea level, and the main part of the battleship has actually completely entered the underwater.

"How did this... do it?" Seeing that the Zi Rihao was completely launched, I remembered to ask why the King of Chuang had such a design.

The King of Chuang probably knew I would ask this before, so he answered very readily: "Actually, it is not difficult to do this at all. You should know what abilities the submarine needs, the president, right?"

I nodded and said, "It's clear."

"Then what abilities do you need?"

I thought for a moment and said, "First of all, a solid sealed shell is needed to ensure that water will not flow in, and it must be able to resist the pressure of the deep sea. Secondly, a propulsion system that can work without oxygen is needed so that it can output power normally under the water surface. There must also be a water detection system such as sonar, otherwise it will become blind once it dives. Oh, by the way, a pressure device and a water tank are also needed. In this way, it can control its own buoyancy through drainage and water injection. It seems that the main part needs these things. In addition, some complicated techniques are needed, and there are quite a lot of things anyway."

After hearing what I said, King Chuang immediately continued to ask: "Okay, just follow what you said. First of all, a sealed and solid shell is needed. Our new warships are all made of high-quality steel in large areas, and the connection parts are made of magic fusion agent. The steel plates can be perfectly integrated into a whole. It is like a whole casting. It is solid and sealed. If we don't want to leave an opening, we can make a fully sealed big can. So we just made some adjustments on all the hatch doors on the warships to increase the sealing ability and ensure that these doors can resist the water pressure of the deep sea."

"So you made a completely sealed shell?"

The King of Chuang nodded and said, "It's not that simple, but it's basically like this. In addition, let me tell you that our new armor has movable reinforcements. These things are usually in a decomposed state to increase the available space in the ship, and can be locked and connected in wartime. On the one hand, it strengthens the overall structural strength of the hull. On the other hand, it can also close a specific area in an emergency to ensure that the hull shell is damaged and can still be submersible without water seepage or pressure resistance disappearing."

The ability mentioned by King Chuang can be said to be very rare, because a large part of the compressive resistance of a submarine actually comes from its shape. It is like an egg. An intact egg that has not been opened has very strong compressive resistance, which is because its structure can disperse pressure and ensure the overall integrity of the shell. It can even be said that pressure makes it strong. As long as the pressure at the unit point does not have a particularly high peak area and can even distribute the pressure evenly, the compressive resistance of the egg even exceeds many metal components. Because if you use iron sheet of the same thickness to make an egg-sized container, but not to make the shape of an egg but instead square, the compressive resistance of this container is definitely not as good as that of an egg.

Submarines also have similar characteristics. When the structure is complete, the pressure generated by seawater will be shared by the structure, and the hull can eventually bear more powerful pressure than imagined. However, once the submarine structure is damaged, such as a large hole in the shell, it will basically have to wait to die. Submarines that lose structural strength can only rely on their own hardness to resist the water pressure, and are mostly the result of being directly flattened.

Unlike submarines, the Purple Ri uses a very special structural method. It is first of all a sea-surface warship, so it does not need to rely on its shell to resist water pressure, so it can be said that it has no water pressure resistance. However, because our designers have installed structural reinforcements for it, and specially laid magic circles to protect the hull with magic power, thus ensuring its resistance to water pressure. In this way, our new warship has become a warship that can not only dive, but also continue to dive after being injured.

"I'm starting to believe that it's really not difficult to dive these boats."

When the King of Chuang heard my words, he nodded immediately and said, "I'm saying it. Our warships use steel structures. Due to the special steel craftsmanship and the assistance of magic arrays, the hardness itself is already very exaggerated. The armor thickness of these large battleships is calculated in meters. Such thickness is definitely beyond any kind of submarine today, so our warships have no problem with pressure resistance. As for the underwater power... have you forgotten what power our warships use?"

The guild's warship propellers use water jet thrusters from Atlantis. This kind of equipment does not need to burn anything, but uses magic energy, that is, magic crystals as power drive. So, since it does not need to burn, it does not require oxygen to fuel, and there is naturally no need to exchange gas. In reality, submarines are equipped with two sets of power equipment and one set of diesel engines. Usually when sailing on the sea surface, or extending the vent pipe out of the sea for diesel-powered navigation in semi-submarine mode. Once you enter the real submarine mode, submarines use electric motors. Not many warships in the game use ore fuel, although it is not used by our guild.

The thrusters of this kind have excellent performance, but in fact, guilds of various countries also have their own magic thrusters. These thrusters are basically powered by magic crystals. Of course, some poor guilds have invented the method of using magicians instead of magic crystals as power. However, that kind of propulsion mode can only be used as an economic mode. During battles, it is necessary to replace magic crystals. In other words, the warships in the game are either sailboats or magic powered by magic. For these warships, it doesn’t matter whether there is air or not, and they are not even afraid of water in the engine, because magic thrusters are not mechanical thrusters at all, and those magic arrays are not afraid of water at all.

Because of this feature in the game, the oxygen problem that plagues submarines in reality almost does not exist for submarines in the game.

What? You ask the person how to breathe halfway? Don't you know there is something called a knight helmet?

Because players are allowed to experience the fun of fighting in different environments, many helmets have underwater respirators. In addition, because the game "Zero" pays attention to everything, even monsters in the wild are born from generation to generation, rather than being directly refreshed, so there must be an explanation for this helmet that can provide oxygen underwater. So, omnipotent magic appears.

The knight's helmet can breathe underwater because it contains a special magic array that can separate oxygen in the water. The prototype of this magic array is the water absorption technique used by mages. Let's not discuss the principle of this water absorption technique. Anyway, this kind of magic is defined in the game, and there is a replica of the magic array form. Then what we have to do is... learn this magic array, and then carve it in certain positions inside the battleship, and then provide oxygen to the entire submarine.

Because of the existence of magic, the very troublesome oxygen problem in reality is almost not a problem in the game. Of course, this is for us. If it is another guild, it will take some effort. After all, the ripping of magic arrays is not as simple as copying a piece of paper. Magic arrays actually have very complex design ideas. Although our guilds have special magic array printing machines that can batch-made magic arrays, that kind of thing is actually a super high-end existence. Generally, guilds have never heard of them, let alone manufacturing them. Only a few guilds have related technologies in this area, but only our guilds can truly batch-print the magic array.

If we reason according to this idea, the new warships in our guild have the ability to resist water pressure, and the water isolation barrier we got from Atlantis is also very simple. Now, with the simple oxygen acquisition ability and magic propellers that can work for a long time without oxygen, most of the necessary conditions for making submarines have been met.

But… “How did you solve the water tank system?”

"Do we need to equip that kind of thing?" The King of Chuang's rebellious question stunned me directly.

On the surface, this problem is very idiotic. How can a submarine solve the problem of diving and floating without a water tank? It can be said that in addition to the power part, most of the remaining space is actually occupied by this water tank and high-pressure air system used to change its buoyancy. It can be said that this system is a very important component in a submarine. But... do our warships need it?

The reason why this batch of new warships has to be replaced is because they have all been replaced. What is the solar furnace? This is an anti-gravity system! When it outputs power downward, it can allow the warship to offset the gravity and fly from the ground, and it can make the warship rise, fall or hover by changing the size of the power output. This control method is very simple, and the response speed is very fast, which can be said to be completely delay-free. However, many people will fall into misunderstandings, believing that this is just a power system that allows the warship to fly, and do not know that this thing system is actually

There is no direction definition. In fact, although the flying warships in our guild have independent jet thrusters, they can actually sail before they are not activated, because the sun furnace itself is a sphere. The direction of its output power can be changed at will in any direction in this three-dimensional space. Moreover, this output can be reversed instantly, that is, if we do not output thrust downwards, but want to go up, the warship will not fly up and sink. Because the huge pressure will force the warship into the water like an invisible big hand.

Because of the abnormal equipment such as the sun furnace, our warships do not need the water tank and air pressure equipment in the submarine at all. When our warships need to dive, they can directly output thrust upwards and let the warship sink. When they need to float, they just need to gradually reduce the power or simply turn the power, and the warship can jump out of the water.

Speaking of this, we have to mention a technical feature of the solar furnace. The power output method of the solar furnace equipment is very distinctive. Although the thrust it outputs is very powerful, it cannot quickly adjust the power size. That is to say, it has no way to burst out all the power in an instant, and it requires a slow adjustment process. The entire adjustment time of a solar furnace from no power output at all to the limit power is about seventy seconds. This time does not change due to the change of the size and total power of the solar furnace, but is a fixed value. In other words, no matter what model of the solar furnace, it will take more than seventy seconds to accelerate to rapid speed, and it will take so long to reduce the power from the limit state to zero.

However, although power adjustment takes time, the power output direction of the solar furnace can be changed strangely at will, and it can even output all power directly in front of the previous second, and the next second, it will completely reversely output all power directly in the rear.

This variability of power direction is a good thing for improving maneuverability flexibility, but because the output power cannot be controlled instantly, it is impossible to stop urgently. Therefore, the solar furnace faces the same problem as the Sterling engine in reality. It is obviously very effective, but it cannot be used for most equipment. For example, even if we equip the solar furnace on a flying warship, we still need to install an additional jet thruster because the solar furnace itself cannot accelerate or close instantly, and can only rely on auxiliary power to achieve emergency acceleration or emergency stop. Of course, if the speed is reduced, the solar furnace itself can be completed. After all, it is enough to reverse the power direction. However, this method is not suitable for general navigation needs. You can also consider avoiding shells on the battlefield. If the power suddenly reverses during actual navigation, it will definitely make all unprepared crew members lose collectively.

Based on the above situation, the sun furnace is only suitable for large equipment such as warships. Because the inertial momentum of these big guys is very huge, so basically, from the beginning of the design, they have not expected them to dance in the sky like birds, so the problem of sun furnace being unable to output power reaction lag can be avoided. Moreover, because the large equipment itself has a large space, there is extra space to install a second set of power equipment, thus ensuring that these big guys can also accelerate or decelerate if necessary. As for small equipment... don't think about it. First, it is difficult to miniaturize the sun furnace, and second, it is very unsafe. The working method of the sun furnace determines that once it explodes.

The power will be equivalent to a super-large equivalent liquefied magic crystal steam bomb. The power of this kind of thing self-destruction is basically the same as that of small nuclear weapons. Large equipment has low combat losses, so there is no problem with installing these things. But if we even install small equipment like mobile angels, it will be lively. Of course, the main reason for not installing is that the power characteristics of the sun furnace are really not suitable for small equipment, especially things on land. After all, there are many obstacles on the ground, and it is not as large as in the sea or in the sky to slow down. Power equipment that cannot adjust power instantly has no other possibility on the ground except to crash. Unless you are only active in plains or deserts.

In any case, our new warships are all equipped with sun furnaces. Although they are ordered to be banned from flying for confidentiality considerations, there is no problem with submarine. Even if the fleets of other countries see our warships diving, they will only think that we are equipped with submersible devices and will not think of the flight function at all. Therefore, this application method does not affect our confidentiality plan at all.

When the King of Chuang saw my expression, he roughly knew that I had figured it out, so he began to introduce it directly: "So, our warships already have the basic conditions for submarine, and because of the existence of detection magic, we can also handle underwater detection. Since these warships first thought of the diving function, all the places where water cannot enter are treated with the waterproof barrier of Atlantis, including gun barrels, etc., and water will not enter. Also, haven't you noticed that the new warships this time are very round in appearance?"

I didn't pay attention to the King of Breaking. This time, the new warships seem to have the characteristics of aircraft in their shape, which is to consider aerodynamics. Because the speed of the warships in the past was not fast, the parts above the water surface basically did not consider fluid mechanics, as long as the underwater part was not strong. However, this time, the new warships can not only fly, but also dive. Therefore, even the parts above the waterline do the composite of the principles of fluid mechanics as much as possible to ensure that the warships have good power appearance in both the submersible mode and the flight mode.

"I have to say that this design makes me quite satisfied." I looked at the Zi Ri, whose diving ability was slowly floating, and said to the King of Chuang beside me: "Then, I will leave this mission to you. I secretly touched the port of the guild and floated up. I want to give them a big surprise."

When the King of Chuang heard me, he knew that I had agreed to their request to perform this mission, so he immediately shouted excitedly: "Please ensure that the mission is completed."

"Don't be proud of yourself. This mission must be careful. Revenge on the British Guild is just to demonstrate our strength. I don't want to go to war with the whole of Europe now. If you cause international disputes on us, don't blame me for throwing you into the river fleet."
