Liquefied magic crystal steam is a high-explosive magic energy solution, which should be in gaseous state, but like most gases, it can be liquefied and stored after pressurization. When liquefied magic crystal steam is used as a weapon, they are generally projected in a liquefied state, that is, they are sealed in a high-pressure cylinder. When the explosives break, because the pressure is lost, the liquefied magic crystal steam will quickly evaporate and turn back into the gas form. In this process, the liquefied magic crystal steam

It will absorb a lot of heat, causing the objects around the target to cool down to more than minus 100 degrees. Then the evaporated magic crystal steam will quickly spread around the surrounding space, and then a detonation similar to a cloud bomb occurs in an instant, causing a devastating blow to the target object and surrounding areas. Because the target object is quickly frozen before the explosion, the texture often becomes brittle, and it is natural to be completely crushed when subjected to the ultra-high temperature and ultra-high pressure generated by the instantaneous detonation.

Because liquefied magic crystal steam has the above characteristics, it can be said that this is a very ideal explosive. Its power and killing effect are far superior to that of chemical explosives under the same unit volume. However, before this, we have almost never equipped liquefied magic crystal steam shells in batches, and at most they only equipped some special artillery with several rounds as special ammunition.

There are only two reasons for limiting the mass equipment of liquefied magic crystal steam shells. One is the price and the other is the activity.

Liquefied magic crystal steam is obtained by crushing, liquefaction, removing impurities, and then performing special conversion to make it have the gaseous properties in the room temperature, and finally pressurized liquefaction. In other words, the raw material of liquefied magic crystal steam is actually magic crystal. Magic crystal is the main energy material in the game, which is equivalent to the sum of coal and oil in reality. Such an important energy material is not only strategic, but also economical. Therefore, even if the output of magic crystal is not low, the price of this thing is still not cheap.

By combining the above factors, we can know that liquefied magic crystal steam is actually a very expensive substance, so the economic pressure will be very high if it is equipped in batches. However, compared with the second obstacle, the first obstacle is actually nothing.

The biggest reason why liquefied magic crystal steam cannot be equipped in batches is not price but activity. The capital chain of our guild can be said to be quite solid. Moreover, because we directly control a large number of magic crystal production areas, the supply of magic crystals in our guild has always been very stable. It is precisely for this reason that the impact of price factors on us is minimal. What is really troublesome is the activity of liquefied magic crystal steam.

The stability of liquefied magic crystal steam has always been very bad. In and outside the game, the only thing I have seen that is more unstable than liquefied magic crystal steam is nitrified glycerin. It only requires a slight vibration or squeezing. Sometimes it even just a sudden change of temperature by a few degrees. Liquefied magic crystal steam will explode suddenly without warning. It can be said that this thing is simply an irregular time bomb, and no one knows when it suddenly explodes.

Of course, the above characteristics are the basic characteristics of liquefied magic crystal steam. Since our guild can be used, there are naturally treatment methods. First, our technicians have found an anti-explosion agent that can effectively inhibit the activity of liquefied magic crystal steam. Although this anti-explosion agent will cause the explosion power of liquefied magic crystal steam to decrease by one or two percentage points, considering the significant increase in safety, this thing is still very valuable. Moreover, at present, the liquefied magic crystal steam of our guild will be added as soon as it is produced, and this regulation has been proven to effectively reduce the incidence of liquefied magic crystal steam explosion accidents in our guild.

Although we equipped certain specific artillery with liquefied magic crystal steam shells before, it was actually a kind of fake shell. That kind of shell was not so much a shell, but a rocket that occurred from the barrel. It was actually a rocket rather than a real cannon.

It is precisely because there are so many troubles in the production of liquefied magic crystal steam shells that I am surprised that this Chris Dyna battleship will be equipped with liquefied magic crystal steam shells as standard. This is a bit scary.

"I actually used the liquefied magic crystal steam shell? How did it do it? Can't I explode the chamber?" Even Kris Dena was surprised when she heard Sophie's answer. Although she was just a mage and not a magic technology researcher, the basic characteristics of liquefied magic crystal steam in our guild are basically aware of some of the basic characteristics of liquefied magic crystal steam. After all, this thing must be used in the front-line personnel in the end, so everyone must understand the characteristics of this thing so as not to cause accidental injury due to improper operation.

While taking us to the No. 2 turret in front, Sophie explained to me: "This problem is solved through many aspects. The first point is that our guns are not driven by gunpowder. Instead, they use the magic version of the electromagnetic coil propulsion principle, so the occurrence process of this cannon is gentler than that of the past cannons. Although the bore-out speed of the shells is one-third faster than that of the old cannons, the peak acceleration is only one-fifth of the old cannons, which means that the squeezing effect of this cannon on the liquefied magic crystal steam when it is fired is lower."

I nodded and said, "But even so, the liquefied magic crystal steam will still explode, right?"

"Of course, this feature cannot be used to prevent liquefied magic crystal steam from exploding in the barrel. The electromagnetic cannon only greatly reduces the pressure, so that we can find solutions from other directions."

"Then how did you solve it?"

"Our solution is actually very simple. The first thing is to stop using integrated charges."

"Don't you need integrated charge?" I hesitated for a moment and suddenly thought of the reason. "Oh, I understand. Liquefied magic crystal steam is not gunpowder. Its explosion effect is similar to cloud explosion bombs, so there is no need for energy-gathering charge technology. Instead, it can use a structure similar to a cluster bomb to disperse all the explosives originally concentrated in one cabin into multiple different containers. In this way, the liquefied magic crystal steam in a single container has a lower quality and will have much better anti-explosion ability."

The principle I am talking about is actually very simple. To put it bluntly, objects with small mass have lower inertia kinetic energy at the same speed. For example, if there are a row of passengers standing in two cars driving side by side, the two cars have the same speed. One of them has one hundred passengers and the other has only ten passengers. The passengers in both cars stand in a straight line along the axis of the body, and the person in the front has a baffle in front. Suppose that the two cars suddenly hit an obstacle at the same time, the passengers in the car must be sliding forward all the way forward. Among the cars with one hundred passengers, stand at the most

The person in front was blocked by the baffle, so he would not slide forward, but if the ninety-nine people behind him wanted to stop the forward inertia, they needed to pass all the kinetic energy on their body to the person in front, and the kinetic energy of one hundred people was concentrated together. The final result was that the person in front suddenly exploded like a rotten watermelon. On the contrary, although the situation happened in the car next to him was similar, the person in front only had to bear the kinetic energy of ten people, so he was only a fracture at most, and his survival coefficient was definitely much higher than the first person in the car next to him.

By the same token, if a large container is filled with liquefied magic crystal steam, when the container suddenly accelerates, the pressure that the liquefied magic crystal steam at the tail of the container will be much higher than the pressure that the last part of the liquefied magic crystal steam in a small container will be subjected to. Therefore, the larger the container, the worse the explosion resistance of the liquefied magic crystal steam storage tank will be. Otherwise, it can improve the explosion resistance.

Of course, the size of this explosion resistance does not increase or decrease in proportion to the volume of the container, but changes according to a certain curve. When the volume is lower than a certain critical point, the effect of reducing the volume is actually very small. Therefore, the containers used in this liquefied magic crystal steam shell should be based on an optimal proportion. They can fully disperse the pressure to ensure the safety of liquefied magic crystal steam, and at the same time reduce the number of charge units. After all, the more complex the structure, the greater the production difficulty.

Seeing that I understood the principle, Sophie continued to explain: "In addition to the bulk charge, the internal shape of the container can actually affect the stability of the liquefied magic crystal steam. Now the liquefied magic crystal steam containers in this liquefied magic crystal steam shell are actually all conical. The tip of the cone points in the direction of the warhead. If you open the fairing outside the warhead, you can see the liquefied magic crystal steam containers arranged inside like warheads. In fact, those are not warheads at all, but because this shape is conducive to resisting the acceleration during launch."

"Is the liquefied magic crystal steam shell safely used just by relying on the characteristics of the electromagnetic cannon and changing the charge form?" asked Kris Dinna.

"Of course there are more than this improvement. In addition to what I just mentioned, there are some other designs. For example, magic energy stabilizes the position. This is a magic array. It is carved on the outer wall of all liquefied magic crystal steam containers, which can ensure further stability of liquefied magic crystal steam. However, this magic array will reduce the explosion power of liquefied magic crystal steam. So we also installed a pre-explosion device outside the container. This thing will explode at 0:00,01 seconds in advance before the shell, destroy the magic array, and then the liquefied magic crystal steam will explode. This can stabilize the liquefied magic crystal steam in the shell without reducing the power of the shell."

"The technology used here should be more than these, right?"

"This is the main technology. In addition, there are some small stable technologies, but they are all double insurances, so there is no difference or not. Just to comfort me. According to the designers of this gun team, the possibility of this liquefied magic crystal steam shell combined with this electromagnetic cannon is far lower than that of the previous guns, so it has completely met the actual combat needs."

In fact, what many people don’t know is that the electromagnetic railgun has a characteristic, that is, the projectile body and the gun barrel will not actually come into contact during the firing process. When the gun is launched, the projectile and the gun barrel need to be pushed out with propulsion gas, so the projectile and the gun barrel need to be fitted as much as possible, just like the cylinder in the engine. If the projectile is too small, the gas generated by the gun powder explosion will leak out around the shell, so the propulsion force will be greatly reduced. This is also the reason why artillery in the past is particularly prone to explosion, because the barrel and the projectile are too close to contact, and the barrel will inevitably deform due to wear and other reasons during the firing process. Once the barrel deforms and the projectile is stuck, then even if the projectile itself does not explode, the launching medicine is enough to explode the barrel.

In contrast to artillery, electromagnetic guns use magnetic fields to propel projectiles and do not need to be sealed at all. Although the electromagnetic force will attenuate with the increase of distance, there is generally no gap between the barrel and the projectile, but after all, there is no need to be airtight. Moreover, the powerful electromagnetic repulsion force will force the projectile to always float on the central axis of the barrel. Therefore, as long as the barrel deformation is not too serious, there will be basically no problem. Besides, the deformation of the barrel of the artillery is mostly caused by wear caused by excessive firing times, or deformation caused by high temperature caused by continuous firing in a short period of time. However, the electromagnetic gun has no friction at all, so there is no way to start with the wear. As for high temperatures or something.

... There is, but it is far less than the high temperature of the cannon. Although the instantaneous temperature of the electromagnetic coil may exceed the temperature of the gunpowder, this temperature will only occur within zero point and zero second. The actual heat generated is not large, so it will not cause the barrel to deform at all. Moreover, because the barrel does not need to withstand the expansion force generated when the propulsion drug explodes, the barrel of the electromagnetic railgun does not actually need to use high-hard steel at all. As long as a support frame is used, the remaining part can be made of refractory materials. In fact, because metal will shield the electromagnetic field, the barrel is destined to be only non-metallic. At least metal materials cannot be used in the inner wall of the barrel.

Just when Sophie explained the principle of using this liquefied magic crystal steam shell to us, most of the boys had climbed to the top of the No. 2 turret. In order not to be blocked by the No. 1 turret, there is a base more than two meters high under the No. 2 turret. In this way, the No. 2 turret will be more than two meters tall than the No. 1 turret, thus giving up the front fire boundary for the No. 2 turret. In fact, there is a No. 3 turret behind us, which is placed directly at the top of the front building of the Battleship Island Bridge, which is more than three meters higher than the No. 2 turret. The three turrets placed in such a staggered manner can ensure the front firepower of the warship, and at the same time it can make the overall structure of the warship more coordinated.

After climbing onto the base of the turret, a few of them went to pull the door handle on the side of the turret, but after a few attempts, they did not pull. These doors are all high-pressure doors, which use self-tightening technology. If you ignore it, the door will automatically close, and the pressurized handle will gradually lock itself to the tightest state.

Children don’t know about this design. However, a few impatient children have already started knocking on the door. With their knocking, the handle on the downward door immediately rotated itself, and then the door opened outward and a head stretched out.

"What's the matter?" What came out was an NPC. There was no precedent for all players to use combat on the warships of our guild. There were only a few players on all the warships. Most of them were NPCs. This Klissina ship was no exception.

The child outside was just excited to see the situation inside, so he knocked on the door, but someone really opened the door but was at a loss. Fortunately, I was below. After seeing the NPC, I waved to him and signaled to let go. The other party immediately walked out and stood by the door and pulled the door open. The children around him were not reckless this time, but saluted and said thank you first before running inside excitedly.

"Let's go up and take a look, too?" Sophie asked.

I nodded and climbed up the hanging ladder directly. Actually, this turret has an internal passage, but because we came up from the deck, we could only go up from the vertical ladder outside.

After climbing to the pedestal, when they walked to the gate, the children and the regiment commander and aunt had already entered the turret. Although there were more than 40 people, because the turret was really huge, they all got into it.

When we walked to the door, I realized that the door of this turret was actually not one door, but three. When the children knocked on the door just now, I guess the door inside should not be closed, otherwise I would not hear the knock outside at all.

The outermost door at the entrance of this turret is an all-metal door that opens outward, with a thickness of about three centimeters, which can be said to be very strong. Of course, considering the power of warship guns currently used by major guilds, the steel plate of this thickness is actually not much different from window paper. However, this door was not originally used to be bulletproof, so it is not a big problem to be thin.

Behind this first door is the real armored door. This door is a telescopic gate embedded in the wall, with a thickness of at least 60 cm. There is a third door behind this door, which is also an open and closed door, but it opens inward. The thickness of this door is nearly fifty centimeters, but it is not all steel. Obviously one-third of the inside is soft substance, and its main function is sound absorption and noise reduction.

Although the thickness of the three doors is more than one meter together, these three doors are not tightly attached, because the entrance to the turret is not a simple wall, but a passage of more than three meters long. In other words, the outer wall of the turret is more than three meters thick. Of course, this thickness is not all armor plates, but at least two meters of which are steel plates, and this defense is really a bunker.

Although the outer wall of the turret is very thick, greatly reducing the internal space, because the turret itself is very huge, the internal environment is different from what I imagined. The space inside the turret is actually far from being as narrow as I imagined. The more than 40 people squeezed in, they were just standing just full, and they didn't even feel crowded.

The space inside the turret is not a regular rectangle, but a concave shape. The missing part of the space in the center is filled with a huge device connected from the floor to the ceiling. I know this thing, but Sophie next to him still actively introduced: "The huge thing in the center is an automatic loader. The left and right guns of this turret have a loading port, but because the two loaders are squeezed back to back, it looks like a whole."

"Sister, what is the caliber and firing speed of this cannon?" a child asked excitedly.

Sophie immediately smiled and said, "Are you quite aware of it? These two cannons actually have no caliber, because they are electromagnetic cannons made of thunder magic arrays. So as long as the shells that can be stuffed into the barrel can be fired normally no matter what caliber you are. This is the advantage of electromagnetic cannons. However, the diameter of our cannon barrel is only 1.65 meters, so the maximum diameter of the cannon cannon should be only 1.64 meters. After all, too large a projectile will collide with the magic array inside the barrel, so the projectiles that need to be fired should be one centimeter smaller than the barrel, so that they will not rub against the magic array inside the barrel. As for the rate of fire... the advantage of this cannon is not the rate of fire, so its rate of fire is actually not fast, at most eight to ten rounds per minute."

Although this speed is indeed slower than those machine guns that can only move dozens of bullets per second at any time, Sophie was obviously too modest. You should know that this thing is not a submachine gun. It is a naval gun. It is also a front main gun. Does this thing take hundreds or thousands of rounds in one minute? Besides, even if it has that kind of fire rate, with the caliber of this cannon, how big is its ammunition depot to keep up with its consumption? After all, the large-caliber shells are not small in size, and the shells fired by this thing weigh several tons per round. Even if Kris Dena is very large, it is impossible for it to carry too many shells for the main gun, right?

Although the children did not understand what the electromagnetic gun was, they still followed Sophie excitedly and asked something else. One of the children probably knew what the electromagnetic gun was, so they asked seriously: "Big sister, what is the range of this electromagnetic gun? I heard that the electromagnetic gun has a long range."

After hearing the other party's question, Sophie immediately said: "If you don't specify a target, let me fire it casually. This cannon can fire the shells to a place a thousand kilometers away, but unfortunately, the actual use distance of this thing is only 200 kilometers."

"Why?"

"Because the enemy is too far away, we can't see it!"

Sophie's answer is simple, but the children seem to understand it, but I understand it. The electromagnetic cannon is flying very fast, so the range will increase accordingly. However, the problem is that there is no self-guided shell technology in the game, and the magic array of guide arrows also needs to be able to see the target before it can play a role. Therefore, even if we can use the pilot ship to investigate in front, we cannot guide the shell to hit the target at such a distance. In addition, there is another problem that affects the range of the electromagnetic cannon, which is its ballistics.

The initial velocity of the electromagnetic gun is too high, so its ballistic is very straight. Although it is impossible for any physical ammunition to really fly out a straight line on the earth, this line will be very close to a straight line. It is okay if the range is short, but the problem will arise when the range is long. Because the earth is round, if the target is too far away, it will be blocked by the raised sea level. If the ballistic is bent, it can be projected. But the problem is that the orbit of the electromagnetic gun is almost straight, so it cannot be projected. As a result, the target is blocked behind the horizon, and the naval gun has no firing angle at all. Of course, although this painful reason limits the range of our cannon, it has to be said that this thing is still the cannon with the farthest range known at present. After all, if the ballistic is not considered, it can shoot a thousand kilometers. This range can only be described as crazy.

After explaining a few words, Sophie gradually lost Naixin, but there were NPCs here, so the captain Sophie directly handed over the commentator's work to several turret operators present, and then she got free herself.

While she was running out to breathe, I asked, "Has this ship been tested?"

Sophie stood on the edge of the base outside the turret, leaning against the safety railing, and then said, "All the warships of the leader class... Oh, I forgot to say. These battleships belong to the leader class, and the Krissina is just one of them. Our warships have basically not been tested. The technical Red Moon seems to have tested basic attributes such as short-range acute acceleration. The Eagle battleship tested the floating system, but all the cannons of the warship were tested in the test site, and they had never tried it if they were installed on the warship."

"Don't you do the test?" asked Kris Dyna.

"This time it is the culmination of the cruising naval, which is also a test voyage. According to the original plan, we will deliberately find several islands at sea to test the power and range of weapons. During the voyage, we will also test the power system. After entering the sea with few ships, we will decide whether to test the floating system depending on the situation."

"We also need to test the floating system?" Kris Dyna asked in surprise: "But there are outsiders on the warship now!"

Before Sophie answered, I said first: "This is not a problem. Just bring the children into the boat in the name of visiting. As long as you can't see the sea, who knows whether the ship is sailing on the sea or flying in the sky?"

"That's right." Kris Dena nodded and said, "Oh, by the way, I'm going to the bridge to drive the warship I named myself. Is this okay?"

"Of course." Sophie said with a smile: "The sea is wide enough anyway, even if you are stupid, you can't rush to the shore, right?"

“Are there still reefs?”

"Do you think I'll let you sail in reefs?"

"That's true!"

As we were talking, we saw the children coming out one after another in the turrets over there. The children were very excited now because they had just heard the NPC inside that the cannons would be tested during the voyage, so they surrounded me and asked if they could watch the cannon test.

Apart from the flight system, the other things of this warship are not secret, so I did not refuse and agreed directly. "I will agree to you first. It's OK to see. But you must obey the command and watch it through the observation window inside the bridge."

"Why?" a child asked slightly disappointed.

"Because the instantaneous detonation of the cannon popping out of the bore is enough to blow you all away." Kris Dena replied. Although this is an electromagnetic cannon, there is no such thing as the gunpowder cannon fire, so it is not as shocking as when it was fired in the past. But this thing has to radiate several times the speed of sound to a shell weighing several tons. So the shock wave is still quite terrifying. Although this shock wave will no longer harm players like us. Most of these children are not of high level, and their attributes are very bad. With their defense, they may not be able to stop these shock waves. Death is not enough. But being blown into the sea is also a problem, right?

Because my explanation was reasonable, the children did not make much noise. Afterwards, at my suggestion, they gave up following us and instead followed a few NPCs that Sophie found to start visiting the situation inside the battleship. The ship is nearly a thousand meters long and it looks like a small city inside, enough for them to play inside, so I have temporarily gotten rid of these energetic little guys.

After the surroundings became quiet, I went to the bridge with Sophie. At this time, the warships had already begun to slowly reverse and leave the port. Half of the warships parked side by side with Klis Dena had already driven out before Klis Dena left, and after we moved, the remaining half followed immediately.

As the largest warship here, the Clissidna is the flagship of this fleet. After leaving the port, Clissidna turned south, while the other warships quickly moved around the Clissidna to form a cruise fleet, and then began to sail with them.

"When will we start the test?" Since I have already boarded the ship, I want to see the test results of this ship. Although I may not have the chance to see the situation of several other leader-class battleships, with the data of this Kris Dyna, I can at least find a suitable target if I need the support of the fleet in the future, right?

After hearing my question, Sophie did not answer immediately. Instead, she looked at the chart first and said, "In about twenty minutes, we can reach an island group. There are uninhabited islands there, so we can find a mountain to test it. But before that, we can test the navigation system first."

"You mean the test of rapid acceleration and extreme deceleration?" Kris Dena asked with some concern.

Sophie looked at Klis Dena in surprise and asked, "Why are you doing this expression?"

Kris Dena said embarrassedly: "Actually, I haven't said it before. I'm a little bit seasick."

"In the game?" Sophie and I were surprised this time.
Chapter completed!
