Starting from Zero

Liquefied magic crystal steam is a high-explosive magic energy solution. It should be gaseous, but like most gases, it can be liquefied and stored after being pressurized. When liquefied magic crystal vapors are used as weapons, they are generally projected in a liquefied state, that is, sealed in high-pressure steel cylinders. When the explosive ruptures, because of the loss of pressure, the liquefied magic crystal vapor will quickly evaporate and return to gas form. In this process, the liquefied magic crystal vapor will absorb a lot of heat, causing the objects around the target to instantly cool down to more than one hundred below zero. After that, the magic crystal steam that will be emitted will quickly fill the surrounding space, and then a detonation similar to a cloud explosive bomb will occur in an instant, causing a devastating blow to the target object and the surrounding area. Because the target object was rapidly frozen before the explosion, the texture tends to become brittle. It is also as it should be by rights that the target object is completely crushed under the condition of the ultra-high temperature and ultra-high pressure generated by the instant detonation.

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

There are only two reasons to limit the batch equipment of liquefied magic crystal steam shells. One is price, and the other is activity.

The liquefied magic crystal steam is obtained by crushing the magic crystal, liquefying, removing impurities, then carrying out a special transformation to make it have the gaseous characteristics at room temperature, and finally liquefying it under pressure. In other words, the raw material of the liquefied magic crystal steam is actually the magic crystal, and the 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 not only has strategic significance, but also has economic value. Therefore, even if the output of magic crystal is not low, the price of this thing is still not cheap.

Combining the above factors, we can know that the 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 to the second obstacle, the first obstacle is actually nothing.

The biggest reason why liquefied magic crystal steam cannot be equipped in batches is not the price but the activity. The bank’s capital chain can be said to be quite solid, and because we directly control a large number of magic crystal production areas, so The supply of magic crystal from the guild has always been very stable. It is for this reason that the price factor has minimal impact on us. The real trouble is the activity of the 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 nitroglycerin. All it takes is a slight vibration or squeeze, and sometimes even a sudden temperature change of a few degrees, and the liquefied magic crystal vapor will suddenly explode without warning. It can be said that this thing is simply an untimed bomb, and no one knows when it suddenly exploded.

Of course, the above characteristics are the basic characteristics of the liquefied magic crystal steam. Since our guild can use it, there is naturally a way to deal with it. First of all, our technicians found an anti-knock agent, which can effectively inhibit the activity of the liquefied magic crystal vapor. Although this kind of anti-knock agent will cause the explosive power of the liquefied magic crystal vapor to drop by one or two percent, it is still very valuable considering the substantial increase in safety. Moreover, the current guild’s liquefied magic crystal steam will add this anti-knock agent as soon as it is produced, and this regulation has been proven to be indeed effective in reducing the incidence of our guild’s liquefied magic crystal steam explosion accident.

After adding this antiknock agent, the activity of the liquefied magic crystal steam will be slightly reduced, so that the safety of the liquefied magic crystal steam can be guaranteed during the general transportation and storage process, as long as the safety regulations are followed. No need to worry about explosion during operation. However, this is only the safety and stability in the process of transportation and storage, but it is another matter completely in use.

The liquefied magic crystal steam in the storage state is static, as long as the temperature change is controlled, there will be no danger. In addition to the temperature during transportation, it will cause extrusion, impact, vibration, etc. due to turbulence. , But because we have used a series of methods to reduce or eliminate the occurrence and extent of these situations, basically the liquefied magic crystal vapor will still be stabilized in a safe state and will not explode.

Although transportation and storage can be guaranteed to be in a safe state, the process of use is completely another matter. Our liquefied magic crystal steam explosives have not been equipped on a large scale before. Later, although they began to be equipped in batches, only two types of liquefied magic crystal steam bombs were actually used, one of which was a throwing bomb, and the other The kind is rocket type.

The types of thrown bombs include aerial bombs and grenades. These are all thrown types. They do not have the ability to fly. They are either thrown down from a high place or short-range projectiles. Two way They all have a common feature, that is, no matter which type, they will only vibrate when they finally hit the target. Before that, they were in a relatively stable state, so there is no need to worry about explosions.

The rocket-like liquefied magic crystal vapor bomb is relatively slightly more dangerous, but the situation is not as exaggerated as expected. First of all, the liquefied magic crystal steam rockets used by our guild are actually very small. The most produced model is the pen-sized liquefied magic crystal steam missile used by mobile angels with a guided arrow magic array. The volume of this liquefied magic crystal steam missile is actually very small, so the mass of the internal charge is relatively small, so it has been greatly strengthened in terms of earthquake resistance and will not easily explode. In addition, rocket boost is not the same as artillery fire. The acceleration process of the rocket is a smooth curve, its acceleration time is very long, and the speed is not fast in the initial period of acceleration, which is why we dare to produce liquefied magic crystal steam missiles but are afraid to produce liquefied magic crystal steam shells.

The liquefied magic crystal steam cannonball, as the name implies, is a cannonball containing liquefied magic crystal steam. Then, as a kind of shell, it must be launched by a cannon, and the principle of the cannon's launch is to use a certain chemical substance to react to produce high-pressure gas that can expand rapidly, thereby pushing the shell out of the barrel. This acceleration process is very short, and the acceleration is extremely terrifying. Unlike the rocket's slow speed in the initial stage, and then faster and faster speeds, the shells reach the extreme speed in an instant at the initial stage of their occurrence. This process is often only a few tenths of a second. Accelerating to several times the speed of sound in such a short period of time, you can imagine how strong the vibration will be in this process. Therefore, even with the addition of anti-knock agents, the liquidized magic crystal steam from the cannon shot is almost 100% undiscussed.

Although we used to equip certain artillery with liquefied magic crystal steam shells, they are actually a kind of pseudo shells. That kind of cannonball is not so much a cannonball, it is a rocket that emerges from the barrel. It is actually a rocket rather than a real cannon.

Because the production of liquefied magic crystal steam shells has so many troubles, I was surprised that this battleship Kristina would be equipped with liquefied magic crystal steam shells as standard. This is too much. It's a little scary.

"The liquefied magic crystal steam cannonball was actually used? How did it do it? Will it not explode?" Kristina was surprised when she heard Sophie's answer. Although she is only a mage and not a magic technology researcher, the basic characteristics of the liquefied magic crystal steam are basically known to our guild players. After all, this thing must be attached to the front-line personnel in the end, so everyone needs it. Understand the characteristics of this thing, so as to avoid accidental injury caused by improper operation.

Sophie took us to the front of the No. 2 turret and explained to me: "This problem is solved in many ways. The first point is because our guns are not propelled by gunpowder. It uses the magic version of the electromagnetic coil propulsion principle, so the occurrence of this cannon is more gentle than the past artillery. Although the ejection speed of the artillery shell is one third faster than the old artillery, the peak acceleration is only the old one. One-fifth of the artillery is lower, which means that this type of artillery has a lower effect on the internal liquefied magic crystal vapor when it is fired."

I nodded: "But even so liquefied magic Crystal steam will still explode, right?"

"Of course, we cannot rely on this feature alone to prevent the liquefied magic crystal steam from exploding in the barrel. The electromagnetic cannon only greatly reduces the pressure, allowing us You can find a solution from other directions."

"How did you solve it?"

"Our solution is actually very simple. The first is to stop using one Make-up charge."

"No need for integrated charge?" I hesitated for a while and suddenly thought of the reason. "Oh, I understand. The liquefied magic crystal steam is not gunpowder. Its explosive effect is similar to cloud explosive bombs, so it does not need shaped charge technology. Instead, it can use a structure similar to a cluster bomb to concentrate the original in one compartment. All the explosives in the blaster are dispersed into multiple different containers, so that the quality of the liquefied magic crystal vapor in a single container is lower, and the anti-explosion ability will be much better."

The principle I said is actually It is very simple. To put it bluntly, the inertial kinetic energy of an object with a small mass is lower at the same speed. Make an analogy. If there is a row of passengers in two cars driving side by side, the speed of the two cars is the same. There were 100 passengers in one car, and only ten passengers in the other car. The passengers in the two cars stand in a straight line along the axis of the car body, and the person in the front has a baffle in front of it. Assuming that two cars suddenly hit an obstacle at the same time, all passengers in the car must slide forward at this time. In the car with one hundred passengers, the person standing at the front would not slide forward because he was blocked by the baffle, but the ninety-nine people behind him wanted to stop the forward inertia. Pass all their kinetic energy to the person in front, and gather the kinetic energy of a hundred people together. The final result is that the person in front suddenly burst like a rotten watermelon. On the contrary, although the situation in the next car is similar, because the person in the front only needs to bear the kinetic energy of ten people, he is only broken at most, and the survival factor is definitely better than that of the first person in the next car. Much higher.

The same reasoning. If a large container is filled with liquefied magic crystal steam, when the container suddenly accelerates, the pressure of the liquefied magic crystal steam in the tail section of the container will be much higher than the last part in a small container. The pressure of the liquefied magic crystal steam. Therefore, the larger the container, the worse the explosion resistance of the liquefied magic crystal steam storage tank. On the contrary, the explosion resistance can be improved.

Of course, the size of this anti-explosion ability 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 volume is reduced again. The effect of is actually minimal. Therefore, the containers used in this kind of liquefied magic crystal steam shells should be based on an optimal ratio. They can fully disperse the pressure and ensure the safety of the liquefied magic crystal steam. At the same time, it can also reduce the number of medicine list elements. After all, the structure The more complex the production, the more difficult it is.

Seeing that I understood the principle, Sophie continued to explain: "In addition to the dispersed charge, the internal shape of the container can actually affect the stability of the liquefied magic crystal vapor. Now this kind of liquefied magic The liquefied magic crystal steam containers in the crystal steam shells are actually all cone-shaped, with the tip of the cone pointing in the direction of the warhead. If you open the fairing outside of the warhead, you can see the liquefied magic crystal steam containers arranged like sub-warheads. , In fact, those simply are not divided warheads, but because this shape is beneficial to resist the acceleration during launch."

"Only relying on the characteristics of the electromagnetic cannon and changing a form of charge can make Is the liquefied magic crystal steam shell safe to use?" Kristina asked.

"Of course there is more than this improvement. In addition to the ones I just said, there are some other designs in this, such as magic power to stabilize the position. This is a magic array, which is carved in all The outer wall of the liquefied magic crystal steam container can ensure the further stabilization of the liquefied magic crystal steam, but this kind of magic array will reduce the explosive formidable power of the liquefied magic crystal steam, so we also installed a pre-explosion device outside the container This thing will detonate at zero point and one second before the shells, destroying the magic array, and then the liquefied magic crystal steam will explode, so that the liquefied magic crystal steam in the shell can be stabilized without reducing the shell’s formidable power."

"There should be more than these technologies, right?"

"This is the main technology, and there are also some small stable technologies, but they are all dual There is no big difference between insurance and the like. It is just a psychological comfort. According to the designer of this gun group, this kind of liquefied magic crystal steam cannon ball with this kind of electromagnetic cannon, the probability of blasting is far lower than before. The gun, so it has fully met the needs of actual combat."

In fact, what many people don’t know is that this thing about electromagnetic railguns has a feature, that is, the projectile body and barrel are actually different during the launch process. There will be contact. When the artillery is launched, the propellant gas needs to be used to send the shell out, so the projectile and the barrel need to be as close together as possible, just like the cylinder in the engine. If the projectile is too small, the gas produced by the explosive explosion will be from around the shell. If it leaks out, the propulsion force will be greatly reduced. This is also the reason why the artillery in the past is particularly easy to explode, because the barrel and the projectile are in close contact, and the barrel will inevitably be deformed due to wear and tear during the firing process. Once the barrel is deformed, the projectile is stuck. The projectile itself did not explode, and the propellant was enough to explode the barrel.

In contrast to artillery, electromagnetic guns use magnetic fields to propel the projectiles, and there is no need to seal them at all. Although the electromagnetic force decays as the distance increases, there is generally not much gap between the barrel and the projectile, but after all, there is no need to be airtight, and the strong electromagnetic repulsion forces the projectile to always be suspended in the barrel. It’s on the central axis, so as long as the barrel is not deformed too severely, there will basically not be a problem. Besides, the deformation of the artillery barrel is mostly caused by the wear caused by too many firing times, or the deformation caused by the high temperature caused by continuous firing in a short period of time. However, there is no friction at all in the electromagnetic gun, so it is impossible to talk about wear. As for high temperature or something... this is true, but it is not as high as a cannon. Although the instantaneous temperature of the electromagnetic coil may exceed the temperature of the gunpowder, this temperature will only occur within zero and one second, and it actually occurs. The heat is actually 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 by the explosion of the propellant, the barrel of the electromagnetic railgun actually does not need to use high-hardness steel at all. As long as a support frame is used, the rest can be made of refractory materials. Make. In fact, because metal shields electromagnetic fields, the barrel is destined to use only non-metallic materials. At least metal materials cannot be used on the inner wall of the barrel.

Just when Sophie explained to us the principle of the use of this liquefied magic crystal steam cannonball, most of the male children have climbed to the top of the second turret. In order not to be blocked by the No. 1 turret, there is a base of more than two meters under the No. 2 turret, so that the No. 2 turret will be more than two meters higher than the No. 1 turret, thus allowing the No. 2 turret. Out of the front firing circle. In fact, there is a No. 3 turret behind us, which is placed directly on 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 staggered in this way can ensure the frontal firepower of this battleship and at the same time make the overall structure of the battleship more coordinated.

After the group of children climbed onto the base of the turret, they pulled the door handle on the side of the turret, but they did not pull after a few tries. These doors are high-pressure doors, which use self-tightening technology. If you leave them alone, the doors will close automatically, and then the pressurized handles will gradually lock themselves to the tightest state.

Children don't know about this design, but a few impatient children have already started knocking on the door. As they knocked on the door, the handle on the inverted door immediately turned on its own, and then the door was opened outward, and a head was stretched out.

"What's the matter?" What came out of it was an NPC. There is simply no precedent for the battleship of this guild that all players are used for battle. All battleships are commanded by only a few players, most of which are NPCs, and this Kristina is of course no exception.

The child outside knocked on the door only because he was excited to see the situation inside, but when someone opened the door, he didn't know what to do. Fortunately, I was underneath. After seeing the NPC, I directly waved to him to let him go, and the other party immediately walked out and stood by the door and opened the door. The surrounding children weren't reckless this time, instead they saluted the other side and said thank you before rushing in happily.

"Shall we go up and have a look?" Sophie asked.

I nodded directly climbed up the hanging ladder. In fact, this fort has internal passages, but because we came up from the deck, we only got up from the vertical ladder outside.

After climbing on the pedestal and walking next to the gate, the children and the head aunt had already entered the turret. Although there were more than forty people, the turret was really huge, so They all got in.

When we walked to the door, I realized that the gate of this turret is not one door, but three. When the children knocked on the door just now, I guessed that the door inside should not be closed, otherwise the knock on the door outside should not be heard at all.

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

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 sixty centimeters or more. There is a 3rd door behind this door. This door is also open and closed, but it opens inward. The thickness of this door is close to fifty centimeters, but it is not made of all steel. Obviously there is one third soft material inside, and its main function is probably to absorb sound and reduce noise.

Although the total thickness of the three doors is more than one meter, the three doors are not tightly fitted together, because the entrance of this turret is not a simple wall, but a The channel is more than three meters long. In other words, the outer wall of this turret is actually more than three meters thick. Of course, this thickness is not all armor plates, but to reach this thickness, at least two meters of which are steel plates, this defensive power is really a bunker.

Although the outer wall of the turret is very thick, which greatly reduces the internal space, because the volume of the turret itself is very large, the internal environment is also different from what you imagined. The space inside this turret is actually far from being as narrow as imagined. The more than forty people squeezed in were just barely 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 occupied by a huge device that connects from the floor to the ceiling. I know this thing, but the 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 loader back to back They are crowded together, so it looks like a whole."

"Big elder sister, what is the caliber and firing speed of this cannon?" A child asked excitedly.

Sophie immediately said with a smile: "Are you quite knowledgeable. These two guns actually have no caliber, because they are electromagnetic cannons made using Thunder Element magic array, so as long as Cannonballs that can be stuffed into the barrel can be fired normally no matter what caliber you have. This is the advantage of electromagnetic guns. However, the diameter of our barrel is only 1.65 meters, so the maximum diameter of the cannonballs that can be carried should be only 1.6 meters. Four, after all, if the projectile is too large, it will collide with the inner magic array, so the projectile that needs to be launched should be one centimeter smaller than the barrel, so that it will not rub against the magic array inside the barrel. As for the rate of fire... …The strength of this cannon is not its rate of fire, so its rate of fire is actually not fast, at most eight to ten rounds per minute."

Although this speed and those who do not move, it takes dozens of seconds per second. The machine gun that fires bullets is really slow compared to what, but Sophie is obviously too modest just now, you must know that this thing is not a submachine gun. This is a naval gun, and it's a former main gun. Does this thing require hundreds or thousands of rounds in one minute? Moreover. Even if it has that rate of fire, with the caliber of this cannon, how big its ammunition depot must be to keep up with its consumption? After all, the volume of large-caliber shells is not small. The shells fired by this thing weigh several tons. Even if Kristina is very large, it is impossible to carry too many shells for the main gun, right?

Though the children didn't quite understand what an electromagnetic gun was, they still followed Sophie excitedly and asked about other things. One of the children probably knew what the electromagnetic gun was, so he asked seriously: "Big elder sister, what is the range of this electromagnetic gun? I heard that the range of electromagnetic guns is very long."

< p> Sophie immediately said after hearing the other party’s question: "If you don’t specify a target and let me shoot at will, this cannon can fire a cannonball to a thousand kilometers away, but it’s a pity that the current actual use distance of this thing It’s only two hundred kilometers."

"Why?"

"We can’t see the enemy because the enemy is too far away!"

Sophie’s answer is simple , And the children seem to understand, but I understand. Electromagnetic guns fly very fast, so the range will increase accordingly, but the problem is that there is no self-guided projectile technology in the game, and the guided arrow demon array needs to be able to see the target in order to function, so even we can use the pilot ship to go. In front of the reconnaissance, there was no way to guide the shells to hit the target so far. In addition, there is another problem that affects the range of the electromagnetic gun, and that is its ballistics.

The muzzle velocity of the projectile of the electromagnetic gun is too high, so its trajectory is very straight. Although on Earth, any physical ammunition is impossible to fly in a straight line, the line will be very close to a straight line. . It's okay if the shooting range is short, but the problem comes when the shooting range is long. Because Earth is round, if the target is too far away, it will be blocked by the rising sea level, and if the trajectory is curved, it can be projected, but the problem is that the orbit of the electromagnetic gun is almost straight, so it can’t do it. Projectile. As a result, the target was blocked by the horizon, and the naval gun had no firing angle at all. Of course, although this relatively painful reason limits our cannon's range, we have to say that this thing is still the longest-range cannon currently known. After all, without considering the ballistics, it can shoot 1,000 kilometers. This range can only be described as frenzied.

After explaining a few words, Sophie gradually lost Nexus, but there are NPCs here, so the captain Sophie directly handed over the job of the narrator to the several turrets present. The operator, and then she freed herself.

Taking advantage of her ventilating effort, I asked: "Has this ship been tested?"

Sophie stood on the edge of the base outside the turret, Leaning back against the safety railing, he said, "All the battleships of the leader class...oh, forget it. These battleships belong to the leader class, and the Kristina is just one of them. Basically, our battleships have not been tested. However, the technology Hong Yue seems to have tested basic attributes such as short-range rapid acceleration. The Eagle battleship tested the floating system, but all the battleship cannons were tested in the proving ground, and the battleship was not tested. Yes."

"Are you not testing?" Kristina asked.

"This is the maiden voyage of the Kristina and also a test voyage. According to the original plan, we will deliberately find several islands in the sea to test weapons such as formidable power and range. In the process, we will also test the power system. After entering the Sea Territory where ships are scarce, we will decide whether to test the floating system according to the situation."

"Will test the floating system?" Kristina was surprised Asked: "But there are outsiders on the battleship!"

Sophie hasn't answered yet, so I said first: "This is not a problem, as long as the children are brought into the boat in the name of a visit. As long as you can’t see the sea, who knows whether this ship is sailing on the sea or flying in the sky?"

"That's what I said." Kristina nodded and said: "Oh, yes. , I’m going to the bridge to drive the battleship I named myself. Isn’t this okay?"

"Of course." Sophie said with a smile: "Anyway, the sea is wide enough, you Even if you are in Ben, it is impossible to rush to the shore, right?"

"Isn't there a reef?"

"Do you think I will let you sail in the Sea Territory where there is a reef? "

"That's true!"

As we were talking here, we saw children coming out of the turret over there one after another. These children are very excited now, because they have just heard from the NPC inside that they will test the artillery during the voyage, so as soon as they came out, they surrounded me and asked if I could watch the test firing of the artillery.

Except for the flight system, the other things in this battleship are not classified as secrets, so I didn't refuse, so I just agreed. "I'll talk to you first. It's okay to see it, but you must listen to the command and watch through the observation window from the bridge."

"Why?" A child asked slightly disappointed.

"Because the instant detonation produced by the cannon ejection is enough to blow you all away." Kristina replied. Although this is an electromagnetic gun, there is no muzzle flame or the like, so it is not as shocking as when the gunpowder naval gun fired in the past, but after all, this thing needs to radiate a multi-ton shell at several times the speed of sound, so That shock wave is still quite terrifying. Although this shock wave will no longer hurt players like us, most of these children are not high-level, and their attributes are very bad. Most of their defensive power cannot stop these shock waves. Death is not enough, but being blown into the sea is also a problem, isn't it?

Because I explained it reasonably, the children didn’t make much noise. After my suggestion, they gave up following us and started with a few NPCs Sophie found. Take a tour of the battleship. This ship is nearly a thousand meters long, and the interior is like a small city, enough for them to play in it, so I can be considered as getting rid of these energetic little fellows temporarily.

After the surroundings became quiet, I went to the bridge with Sophie. At this time, the battleship had begun to slowly reverse and leave the port. Half of the battleships that had been parked on the berth alongside Kristina before had already left before Kristina left, and the remaining half followed immediately after our side moved.

This Kristina is the largest battleship here, as it should be by rights is the flagship of this fleet. After leaving the port, Kristina turned to the south, and the other battleships quickly moved around the Kristina to form a cruise fleet, and then began to accompany the cruise.

"When will we start testing?" Now that I have boarded the ship, I want to see the test results of this ship, although I may not have the opportunity to see the situation of several other Boss-class battleships. But with the data of this Kristi
