Chapter 522

After giving me the instructions for extracting energy, the little rosefinch started her explanation again. "The material you see now is black, so you can all see it clearly, right?"

Everybody nodded.

"OK. Now I've pulled up a flame spell, and the orbs float here. As long as I let go of control, they will be broken down and absorbed. " As she said this, she released her control of the spell, and the dots of red light began to drift towards the material below. The rosefinch said: "now it starts to absorb energy, but this guy's volume is very large, this small fireball is not enough to make it completely invisible, so I'm starting to add energy to it." With the continuous output of rosefinch, although the fireball is constantly absorbed, it does not disappear.

The material is constantly absorbing energy, and it gradually becomes invisible. When it completely becomes invisible, the little rosefinch smashes the fireball. "Well, now you're looking at material that's already invisible. It's on the ground now, and under it is the soil. Do you see the ground through it? "

Everyone shook their heads at this time. This thing is not totally invisible now, its color has become a light white, and it seems that there are some blue mixed in it. How do I think it looks like the color of the sky. I finally understood that this thing was not transparent, but became the color of the sky. Eisinger ruins here is by the sea. There is no contrast near us. When it is connected with the sky and sea in the background, it is completely invisible. In fact, it is not transparent. Even if there is a contrast, it can be easily found.

Woma suddenly asked the rosefinch, "what's the name of this material?"

"At the beginning, Nuwa Niang didn't give this thing a name. They were just scum."

Woma immediately said, "is it OK for us to name?"

"Of course." Zhu que is very polite way: "anyway, it's for you. I can't care how you call it."

Woma looked at me: "president. The properties of this material are so suitable for eisenegger's flight plans in the future. Can we just call it the sky stone? "

"The name doesn't matter. The key is the purpose. What do you mean by flying technology

Voma immediately explained excitedly: "Eisinger can be launched, and this material can be easily integrated with the sky. If there is a city with the same color as the sky, who can see it? If there is a way to extract energy, we can even drain it at night and turn it black. In the future, no one will find it unless Eisinger lands

"Yes, this property is really good." An invisible moving castle. I think it must be interesting.

The little rosefinch said: "the sky stone you named is not only invisible in the sky, but also a good anti magic barrier. I've explained to you just now how it absorbs magic. Magic beyond 20 meters or under continuous control will not be affected. Therefore, your defense operations also need some adjustments. First of all, the mages must slow down the use of magic

"Doesn't that affect our combat effectiveness?" Asked a mage.

The little rosefinch shook her head: "it will affect your combat effectiveness, but you should consider that the enemy is worse than you. Let you slow down the release speed of the spell is the power. It requires you to control your spell. No matter how long it leaves the range of 20 meters, release the control and let it fly by itself. Otherwise, all the spells will be sucked back. Your spell control distance should be more than 20 meters, after all, this distance is not very long. I know that most people are used to letting go of control after a spell flies 5 meters, but if you want to use a spell in a city built by Sky City, you must learn to control the distance of the spell release. To know that your enemies are more difficult than you, you just need to throw the spell 20 meters away. They can't expect the magic to work unless they can control the magic to hit the target all the time. In fact, except for the existence of our gods, the general mage can't control the magic beyond 100 meters. That is to say, few people have the ability to put magic on your walls. Besides, as long as you are careful to avoid, there will be no problem. Even if the spell is launched above the wall, once it touches the sky stone, it will be sucked dry like water meets a sponge, and it will not cause any damage at all

A warrior player asked, "how hard is this thing? It's good to be afraid of magic. What about physical defense? "

"I can only say that it's harder than ordinary materials, but I haven't tested how strong it is."

A German female player called, "take a few pieces and experiment with it."

The rosefinch even said, "anyway, the things are for you. I don't care how you want to use them. But I have to make it clear to you in advance that there are so many things that it is not enough to build your city. It can only be mixed with other materials. If you consume too much in other aspects, I can't give you any more."

"We'd better not experiment." Another player's heartache."In fact, it's not impossible to experiment, but you must be careful not to damage it too seriously. This kind of material has the ability of self-healing. If a crack is made or a piece is missing, as long as there is energy flowing in, it will automatically repair the damage, provided that the damaged part does not exceed 75% of the total volume. "

"Then don't worry." "We're not that violent yet," I said with a smile

There are many parts to test the firmness of a material. The first is to test the impact resistance. In order to make a comparison, we made some solid steel embryo, the shape is exactly the same as the sky stone, so it is more convenient to compare.

First of all, we set up the sky stone and the steel embryo, and then the puppet smashed it with a heavy hammer. The power of the puppet is very strong, and its power is even more powerful after using the large Warhammer. First of all, the puppet swung the sledgehammer and swung to hit the steel embryo in the same posture as throwing a hammer.

When a loud noise, our ears were all shocked tinnitus for half a day. The percussion was a little bit unexpected. We thought it would just sink a little, but the puppet broke the hammer. The head of the huge hammer was embedded in the steel embryo, but the puppet had only a bare stick.

Erlang God touched the hammer head in the steel embryo and said, "purple sun! Is your puppet much stronger than mine? "

I wryly smile way: "they also fell strength big!" As like as two peas were damaged,

had to replace a hammer with the same hammer for the second time. Order the puppet to use the same force to hit the sky stone, and then we plug their ears and wait for the bang to happen. The puppet is still in the same position and spins and hits the surface of the sky stone with a hammer.

Boom! "Oh

I don't know whether it's the magic puppet's strength is too strong or the quality of our hammer is defective. Anyway, the hammer head was knocked off again this time. The metal handle in the puppet's hand has been bent into the shape of the letter Z, while the sky stone is not damaged, but we found a strange change. The sky stone we used for our experiment was drained of energy, and it is now black, but the color of the sky changes near the place where it was hit. The sky stone can only change color when it absorbs energy. Can it absorb the mechanical energy when it hits repeatedly?

I was thinking, suddenly a player said: "strange, where is the hammer head?"

When he said that, everyone began to look for the hammer head, and they found two unfortunate guys at the same time. The first guy was seven or eight meters behind us. He fell on the ground and rolled, and his left leg had disappeared below the knee joint. Another man is now lying on all fours behind us, and there are two people under him.

The handle of the hammer was broken when the puppet struck the stone of the sky. Because the hardness of the stone in the sky was quite exaggerated, the hammer head did not sink in as it had just hit the steel embryo, but bounced out. The hammerhead that was bounced off first broke the leg of the first guy, then hit the ground and bounced up again, hitting a guy in the back's stomach, and that guy was knocked out and knocked down two people by the way.

I saw those people miserable and touched the stone of the sky again. "Hard enough! I just don't know if there is the same effect after freezing! " Generally speaking, many hard objects become very fragile after freezing, such as steel. Once the temperature is low enough, they will become as fragile as glass.

With the help of the queen of ice and snow I summoned, we cooled the sky stone to a very low temperature with a new steel embryo, because we couldn't use cryology directly on the sky stone, we delayed a little bit. When the cooling was done, we tried the blow test again. At this temperature, the steel was as brittle as glass. The puppet smashed a large piece of steel embryo down with a hammer, but the sky stone still did not respond.

Low temperature doesn't work. We tried high temperature again, but it didn't work. When the temperature exceeds 120 degrees, the sky stone will no longer heat up, but will directly convert the temperature into energy and absorb it. To continue heating is to supplement energy to the sky stone, which has no significance at all.

In the next wear test, we use large and large grinding machine, but the wear effect is very poor. After using a whole grinding stone, we only left a one foot deep hole on the surface of the sky stone. Under normal circumstances, a grinding stone should be able to open a two meter deep hole in the steel plate, but now it is only one foot deep. Although this experiment proved that the sky stone is not indestructible, at least it can be polished and cut, but its hardness is no doubt.

Originally, we planned to do the pulling experiment and the torsion experiment. Considering the size of the sky stone, we didn't have such a big machine. All experiments show that the sky stone has extraordinary properties and is fully competent to build cities.

After examining the hardness, we began to calculate the use of materials. The rosefinch has clearly said that the materials are not enough. Of course, we can not directly start building cities. The first work is to calculate and calculate the actual amount of materials used, so that we can arrange reasonably.

The result of calculation is just like the little rosefinch said, the material is not enough. In order to make rational use of it, we have to plan again where to use the sky stone and where to use the substitutes. First of all, the outermost layer of the city must use the sky stone. After this amount is deducted, the rest will be calculated.Until the afternoon, we made a general plan to use the puppet. The impatient Erlang God began to direct the puppet to work. The first thing we need to build is the bottom armor of the city. At the beginning of the design, it was planned that the city should use modular design. Of course, the armor should use removable structure according to the modular standard. According to the design, the bottom of the city is a 32 kilometer square, which will be protected by 1024 armor plates.

Each armor plate is actually a cube 1000 meters long, 1000 meters wide and 100 meters thick. The bottom 30 meters of the cube is completely made up of sky stones. They have magic resistance and invisibility on the outside. The smooth sky stone will not stick anything, and even if it takes off from the ground, it will not lose its invisibility effect because of a large amount of clay. In the sky above the stone will be placed about 70 meters thick colorful God stone. Although in terms of structure strength and magic resistance, the multicolored God stone is not as good as the sky stone, but this thing is open to supply, don't worry about the quantity!

In fact, I wanted to place steel plates on the armor layer, although it was not as strong as the sky stone, at least stronger than the colorful God stone. But in the end, considering the weight, we gave up the idea. The density of the sky stone is very small. I feel that it is almost the same density as foam plastics, and it will not sink when thrown into the water. Even the wind above six level can blow it up. The density of the colorful stone is smaller than that of the sea water. It can float like wood in the water. The density of these two materials is not large, which is very suitable for the construction of Eisinger. Our gravity resistance device is very powerful, but who doesn't want to save a little? At least we can save a little bit of magic stone. If Eisinger loses its power at sea, the city built with such light materials may not sink. At that time, the forced landing on the sea can at least be used as a ship.

The armor plate is made separately. Anyway, it will be assembled at one time at the end, so now it is manufactured in large quantities according to the standard. In addition to the bottom armor, the wall also needs to be protected, so the actual need to build is not only 1024 pieces, but also a lot of walls. Fortunately, the number of Erlang God's puppets is so large that they can be made quickly.

We're going to pile up 30 square meters of rock into a square. After completing this layer, the wucaishen stone will be piled up in the same way. After the completion, xiaozhuque and Erlang gods will hold the fusion symbol and paste it. Then the structure of these stone bricks will become a whole. Not only are the sky stones connected, but also there is no fault at the joint of the sky stone and the colorful God stone, as if they were completely grown together. If our guild has this kind of rune, we don't have to use welding machine to weld the hull. Unfortunately, Erlang God refused to give me this kind of Rune.

While making armor, other players are directing the guild's puppets to carry the sky stones. They have the puppets pile the sky stones into metal shells made in advance. These metal shells are all steel columns with different lengths. The longest one is as long as 30 kilometers. Judging from the terrible welding traces, it took a lot of work to make these things. Steel columns vary in diameter, but they are empty inside. After the sky stone is put in, it forms a stone pillar shape. With a paste of the fusion symbol, the sky stone piled in becomes a real stone pillar. After pouring the stone pillars out of the metal shell, the players began to refill the sky stones. These steel pillars are actually just molds to make beams quickly and accurately.

Huge cities need support. Once such a big city flies, the strength of its base is unimaginable. In the past, the bottom of the city was a whole piece of rock with enough strength to support the weight, but now the city is modular. The armored part not only does not bear the support force, but also consumes the strength of the support system. Therefore, we need to build a strong enough support structure.

Our guild has the internal support technology from the turtles, and the excellent performance of sky stone, a super material, we can easily complete this support system. In fact, we have calculated that although the size of the new eisenegger will be a full circle larger than the original, the total weight will be less than one sixth of the original. Of course, this is due to the excellent performance of the new materials.

The largest supporting crossbeam is 30 kilometers long, and the bottom surface is a square with a side length of 300 meters. Even if the density is almost the same as that of foam plastics, such a large beam will still weigh up to 100 tons. If it weren't for the heavy lifting equipment in our guild, it would be very troublesome.

Due to the large number of personnel and reasonable design, our construction progress is extremely fast. In the middle of the night, aisinger's bottom rack has been completed, but now it's only a keel. Besides the support frame, nothing has been installed. But as long as this is completed, the speed of connecting various devices will be much faster.

During the night, some huge secret equipment was transported to Eisinger, all from steel city. These days we are building Eisinger, and the restoration of the steel city side has been completed. The new steel city has not only been expanded, but also added equipment. In the past, because of mining and construction, the city was in a mess. This time, all of them were planned by means of reconstruction. Now steel city is basically like a factory. It doesn't look like a garbage dump before. These new equipment is the first set of products after the completion of steel city.After the steel city equipment was delivered, another garment of material came from the sea, this time from Atlantis. After the combination of the white shark and mermaid, they used their technology to complete the new equipment we ordered secretly. The idea of these things came from a member of the guild Design Bureau, but we have to admire his intelligence. In fact, the reason why aisinger's design has been adjusted so much this time is because of his novel design, because his design will enable him to have the ability to move. Therefore, we have made great efforts to transform the city into a mobile fortress. Of course, another reason is that someone pays for us. We don't have to worry about the renovation cost.

But we're still going to assemble the equipment in Atlantis, and we'll continue to assemble the equipment with the city of Atlantis. First of all, the technicians put up some huge disks, which are made of the mixture of Mo steel and Atlantis special alloy. Their strength is probably the highest among the equipment we have made. Even compared with the sky stone, I believe it will not be too bad. These huge disks alone have consumed us nearly 50 million crystal coins.

The disc was erected and began to be assembled with other models. When they make up a complete part, everyone can see that it's actually a huge wheel. This super metal wheel has a diameter of 70 meters, which is almost 20 stories high. Compared with the height of these wheels is more prominent is the width, the huge wheel width of 500 meters, almost like a drum.

These huge wheels surprised most of our members because they didn't know what it was for. What's more, there are more than one of them. After the first one is finished, the technicians begin to direct the puppets to assemble the second and the third. It seems that there are still many of them.

At daybreak, 3200 of these wheels are stacked on the ground, which startles those who don't know. What are so many giant metal wheels for? Almost everyone is guessing about it.

After these wheels were finished, our technicians started to play with new things. This time, it's a huge machine. As long as the people in our guild don't know it. This is the most common gravity resistant device. But this time the equipment is a little different. This time, the gravity resistance devices are much smaller than the normal size, and each device seems to have more parts, but it is not clear what these new parts are for.

The technicians asked the puppet to make some strip boards from the sky stone. They are all the same size, about 500 meters long, slightly wider than those wheels, about 50 meters wide, and all 8 meters thick. These strips were wrapped up by technicians with some of the metal items that had been transported. It seems that these sizes were planned at the beginning, because the metal cladding was just right in size to hold the long board of sky stone. After the package, the slabs were swung apart in two, and the researchers placed gravity resistance devices on these special plates, which were also designed in terms of size. The protrusions from the metal holder just fit into the holes in the gravity resisting devices. After placing the gravity resistance device on the board, the researchers attached another board to the device, so that the gravity resistance device was sandwiched between two plates.

The stone slab is long, but the resistance device is very short. A resistance device is placed on one side of the board, and the gap is filled with some sky stones. After the completion of the structure, it was covered with a metal shell made in advance. This time, there were some strange devices on the shell, which looked like a probe protruding out.

When the metal parts are connected to the stone slab of the sky stone, they become a strange long strip, but we still can't see what it is for. In the afternoon, the technicians finally began to use the strips, until then all of them suddenly understood what it was, even the function of the wheels.

These bars are crossed one by one, and then the connections on the metal shells just lock each other. After a busy afternoon, 400 tracks are completed. These are as like as two peas of a tank. Apart from the larger size, they are almost no difference. What we saw was that they were tracked. However, we are still very curious, why should we install gravity resistance devices in these tracks?

Another sleepless night, Eisinger's construction is still in full swing. The fleet on the sea brought new cargo, and technicians directed the puppet to carry a large amount of equipment ashore. These devices are huge and frightening to look at. Some parts are like gantry cranes on the wharf, but they are much bigger. The materials unloaded overnight were quickly used.

First the technicians spread a track flat on the ground, and then they put eight big wheels on it. I'm in charge of luck and plague, and I'm helping to connect some weird devices. When completed, the equipment looks like the big diesel engine used on a luxury yacht, but it's very large in size. These engine like devices are actually engines, but they don't burn diesel, they're powered by magic crystals.

The researchers ordered the puppet to connect eight metal supports with the letters y reversed, and we connected the power equipment. The eight inverted Y-shaped supports are mounted on the bearings of the eight wheels, and then the drive shaft of the power plant is connected to the support frame. This inverted Y support is not only a support, but also a transmission device. When all this was done, the researchers ran the tracks off the wheels and buckled them to death.Now if anyone can't see what it is, it's hard to say. It's just a crawler propulsion device. The only special thing is that there's a gravity resistance device in the track splint.

The researchers assembled the rest of the parts in this way. After the completion of 400 crawler propulsion devices, it was very spectacular. The huge tracks and the supports were like mobile buildings one by one.

That's not all. The third piece of equipment has finally arrived. The quantity of this shipment is small, but the volume is larger. What we see is a jack like device, of course, much larger. As like as two peas, there are 401 devices, 400 of which are exactly the same, only one special big one.

The researchers directed the totem dragon in the guild to turn over these 100 meter high super jacks one by one. Thanks to the totem dragon and guardian beast, they are guild guardians and do not disappear because of the destruction of isinge. Otherwise, we really don't know how to assemble these super huge parts!

These Jack like devices are turned upside down and connected to the crawler propellers, and the thick metal support posts protruding from the jacks just fit into the holders on those supports. The function of these Jack equipment is very simple, they can extend or shorten the metal support column, in addition, they can also rotate, the function is only these two.

When these devices were installed, people understood their purpose more clearly. In the eyes of everyone, the researchers finally came back to install the devices. But instead of moving the crawler propellers, they got the biggest Jack first.

The biggest "Jack" is very strange in shape. It looks like two jacks connecting the central support column, that is to say, it looks like two head to head jacks.

The researchers asked the dragon to take it to the center of the city. Originally, those who directed the construction did not understand why the framework of the city should be built with the sky stone first. Now they understand the reason. This super jack is as high as 800 meters. If it wasn't for the frame, it wouldn't come in at all.

The jack was placed in the center of the city, and then some people climbed up and manually operated the jack to extend until the upper one hit the beam. Construction workers began to fix the jack above, using the parts that came with the jack, and they quickly connected it to the city frame.

The researchers first experimented with the retraction jack, because the top of the jack was connected to the frame, and the bottom naturally left the ground. After confirming that it would not loosen, the researchers stretched it out to lift the city's frame and ordered the temporary supports to be removed. When all the temporary supports were removed, the city was completely supported by jacks.

Again, we experimented with stretching and shrinking the jack, and the city frame moved up and down. To make sure that there is no problem with expansion and contraction, we start to rotate the jack. The jack can rotate freely from left to right, but the speed will not be too fast. The lower half of the jack supports the ground, while the upper half rotates, the city frame rotates with the jack. This is the steering equipment we designed. How convenient it is!

The amount of RMB 8000 in this chapter has made up for the amount of RMB 2000 owed yesterday, which is now leveled. In addition, I would like to thank the reader who proposed the improvement of gravity resistance device.
