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

Everyone nodded.

Zhuque continued: "Okay. Now I dragged up a flame spell, and the spell balls floated here. As soon as I let go of control, they will be decomposed and absorbed." As she said that, she released her control of the spell, and the red highlights of stars began to float towards the material below. Zhuque said: "Now it is starting to absorb energy, but this guy is very large, and this small fireball is not enough to completely enter the invisible state, so I am now starting to replenish energy." With Zhuque's continuous output, although the fireball was constantly absorbed, it did not disappear.

The material was constantly absorbing energy, and it began to gradually become invisible. When it completely became invisible, the little Vermilion Bird crushed the fireball. "Okay, what you see now is the material that has entered the invisible state. It is now placed on the ground, and under it is soil. Do you see the ground through it?"

Everyone shook their heads together at this time. This thing is not completely invisible now. Its color has become a light white, and it seems that some blue is mixed in. No matter how I look at it, it feels like the color of the sky. I finally understand that this thing is not transparent but has become the color of the sky. Here is the seaside here. There is no contrast near us. When it is connected to the sky and sea in the background, it is completely invisible. In fact, it is not transparent, and even as long as there is a contrast, it is easy to be discovered.

Woma suddenly asked Zhuque: "What is this material called?"

"Nuwa did not name this thing at the beginning, they were just waste."

Woma immediately said: "It's okay for us to name it?"

"Of course." Zhuque said politely: "Anyway, it's for you, and I can't control it no matter how you call me."

Woma looked at me: "President. The properties of this material are so suitable for Aisinger's flight plan 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 what you mean by suitable flight technology?"

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

"Yes, this property is really good." I think it must be interesting to have an invisible mobile castle.

Little Suzaku said: "The sky stone you named can be invisible in the sky, but it is also a good anti-magic barrier. I have explained to you just how it absorbs magic. As long as it exceeds 20 meters or is under continuous control, it will not be affected. Therefore, your defense operations also require some adjustments. First of all, the mages must slow down the use of magic."

"Didn't that affect our combat effectiveness?" asked a mage.

Little Suzaku shook his head: "This will indeed affect your combat effectiveness, but you have to consider that the enemy is worse than you. Slowing down the spell release speed is the power that requires you to control your spells. No matter how you wait until it leaves the range of 20 meters before letting it fly by itself, otherwise all the spells you shot will be sucked back. The spell control distance of your land should be more than 20 meters, after all, this distance is not very long. I know that most people are used to letting out the control after the spells fly 5 meters, but if you want to use spells in cities built in the sky, you must learn to control the spell release distance.

It is more difficult for your enemies than you. You can just throw the spells 20 meters away. They don’t expect the spells to be effective unless they can always control the spells to hit the target. In fact, except for us god-level existences, ordinary mages cannot control the spells to a distance of 100 meters. In other words, almost no one has the ability to hit your city wall. Besides, you will not have any problems as long as you pay attention to avoiding them. Even if the spells are fired onto the city wall, once they touch the sky stone, they will be immediately sucked dry like water encounters a sponge, and will not cause any damage at all."

A warrior player asked: "How is this thing hard? Not afraid of magic is a good thing, what about physical defense?"

"I can only say it is harder than ordinary substances. But I have not tested how strong it is."

A German female player shouted: "Just take a few pieces to experiment."

Zhuque hurriedly said, "Anyway, I'm giving it to you. I don't care about how you want to use it, but I'll explain it to you in advance that there are only so many things. It's not enough to build your city, so I can only mix it with other materials. If you consume too much in other aspects, I can't supplement it."

"Then we should stop experimenting." Another player said with distress.

Zhuque said: "Actually, it is not impossible to experiment, but you must be careful not to damage it too much. This material has the ability to repair itself. If a crack is broken or a piece is missing, as long as energy flows in, it will automatically repair the damage. However, the premise is that the damaged part does not exceed 75% of the total volume."

"Then don't worry." I smiled, "We're not that violent yet."

The strength of a material is divided into many parts, first of all, to test its ability to resist strikes. In order to make comparisons, we made some solid steel embryos, which are exactly the same as the sky stone, which makes it more convenient to compare.

First we set up the Sky Stone and the Steel Bulletin, and then the Magic Puppet used a heavy hammer to smash it. The Magic Puppet was very powerful, and after using a large warhammer, it was even more powerful. First, we knocked the Steel Bulletin, and the Magic Puppet swung the sledgehammer and smashed the Steel Bulletin in a pose like throwing a hammer.

With a loud bang, our ears were all tinnitus for a long time. The knocking situation was a little unexpected. We originally thought it would just sink a little. But we knew that the puppet actually broke the hammer. The huge warhammer head was embedded in the steel embryo. The puppet had only a bare stick left in the puppet's hand.

Erlang Shen touched the hammer head in the steel embryo and said, "Purple Sun! Is your earth puppet much more powerful than my earth puppet?"

I smiled bitterly and said, "They have become more powerful!"

Because the hammer was damaged, the second time we had to change to a exactly the same hammer. We ordered the puppet to use the same power to knock the Sky Stone, and then everyone blocked their ears and waited for the loud noise to happen. The puppet still rotated in the same posture and smashed the surface of the Sky Stone with a hammer.

Boom! "Oh!"

I don’t know if the magic puppet’s strength is too strong or the quality of our hammer is problematic, but this time I knocked off the hammer head. The metal handle in the magic puppet’s hand has been bent into the shape of the letter z, while the Sky Stone is not damaged at all, but we discovered a strange change. The Sky Stone we used to do the experiment was drained from energy, and it is now black, but the near position that was hit has turned into the color of the sky. The Sky Stone will only change color if it absorbs energy. Can it absorb the mechanical energy during the strike?

I was thinking, and suddenly a player said, "It's strange, where is the hammer head?"

After he said this, everyone started looking for the hammer head, but everyone found two unlucky guys at the same time. The first unlucky guy was seven or eight meters behind us. He fell to the ground and rolled, and his left leg and knee joint were gone. The other person was now lying on the sky above and about forty meters behind us, with two people under him.

The hammer handle was broken just now when the puppet hit the Sky Stone. Because the hardness of the Sky Stone was quite exaggerated, the hammer head did not sink in like the steel embryo just now, but rebounded. The bounced hammer head first broke the first guy's leg, then hit the ground and bounced up and hit the belly of a guy behind. The guy was knocked out and knocked down two people.

I saw those people touching the Sky Stone again. "It's really hard! I just don't know if there is any effect after freezing!" Generally speaking, many hard objects will become quite fragile after freezing, such as steel, and once the temperature is low to a certain extent, they will become as fragile as glass.

With the help of the Snow Queen I summoned, we cooled the Sky Stone and a new steel embryo to a very low temperature. Because we could not use the freezing technique directly on the Sky Stone, we delayed a little time. After the cooling was completed, we tried the strike experiment again. At this temperature, the steel was as crisp as glass. The puppet went down with a hammer and knocked out a large piece of the steel embryo, but the Sky Stone still had no response.

Low temperatures are ineffective, we experimented with high temperatures again. However, the experiment failed. When the temperature exceeded 120 degrees, the Sky Stone no longer heated up, but directly converted the temperature into energy and absorbed it. Continuing to heat up was equivalent to replenishing energy to the Sky Stone at all.

In the next wear resistance experiment, we used a large and large grinder, but the wear effect was very poor. After using a whole grinding stone, we only left a one-foot-deep pit on the surface of the Sky Stone. Under normal circumstances, a grinding stone should be able to make a two-meter-deep hole in the steel plate, but now it is only one-foot-deep. Although this experiment proves that the Sky Stone is not undestructible, and at least it can be polished and cut, the hardness of it is no longer questionable.

We originally planned to do pulling and torque experiments. We should consider the size of the Sky Stone on time, so we don’t have that big machine. All experiments show that the Sky Stone has extraordinary ground attributes and is fully qualified to build cities.

After examining the hardness, we began to calculate the use of materials. Zhuque has clearly stated that the materials are not enough. Of course, we cannot start building cities directly. The first job is to count and calculate the actual amount of materials used so that we can make reasonable arrangements.

The calculation results are as Xiao Zhuque said, the materials are not enough. In order to make reasonable use, I have to plan again where to use the Sky Stone where to use the substitute. First of all, the outermost layer of the city must use the Sky Stone. After deducting this amount, the remaining part will be calculated.

We had a rough plan to use it until the afternoon. Erlang Shen, who had been impatient for a long time, began to direct the doll to work. The first thing we need to build is the armor layer at the bottom of the city. When we were originally designed, we planned to use modular design in the city. Of course, the armor must use a detachable structure according to modular standards. According to the design plan, the bottom of the city is a square with a side length of 32 kilometers, which will be protected by 1,024 armor plates.

Each armor plate is actually a cube that is 1000 meters long, 1000 meters wide, 100 meters thick. The thickness of the bottom 30 meters of this cube is entirely composed of Sky Stones. They have magic resistance and invisible effects outside. The smooth Sky Stone will not stick anything to it, and even if it takes off from the ground, it will not lose its invisible effect because of sticking a lot of soil. A five-colored divine stone about 70 meters thick will be placed on the Sky Stone. Although the five-colored divine stone is not as good as the Sky Stone in terms of structural strength and magic resistance, this thing is open and there is no need to worry about quantity!

Actually, I originally wanted to install steel plates on the armor layer. Although they are not as strong as the Sky Stone, at least stronger than the Five Colored Divine Stone. But in the end, considering the weight issue, we gave up this idea. The Sky Stone is very small. I feel that it is almost the same as the foam plastic, and it will not sink at all if it is thrown into the water. Even winds above level six can blow it up. The Five Colored Divine Stone is smaller than sea water, and 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 Aisinger. Although our gravity resistance device is very powerful, who doesn't want to save a little? At least the magic crystal consumes a little energy. If Aisinger loses power at sea in the future, a city built with such light materials may not sink. At that time, it will be used as a ship when it is forced to land on the sea.

The armor floor is made separately. Anyway, it will be assembled at the last time, so it is now manufactured in large quantities according to the standards. In addition to the bottom armor, the city wall also needs protection, so there are not only 1,024 pieces that need to be built, and there are also a lot of land for the city wall. Fortunately, Erlang Shen has a large number of dolls and is faster to make.

The dolls first move the Sky Stone over and pounce into a square with an area of ​​one square kilometer, and then pile up the thickness to 30 meters. After completing this layer, they piled up the colorful divine stones in the same way. After all, the Little Zhuque and Erlang Shen will personally hold the fusion talisman and paste them on it, and the structure of these stone bricks will become a whole. Not only will the Sky Stone be connected, there is no fault in the place where the Sky Stone and the Five Colorful Divine Stone are joined, but it is like they are completely grown together. If our guild has such a talisman, we will use a welding machine to weld the hull. Unfortunately, Erlang Shen refused to give me such a talisman.

While making armor, some other players were directing the guild's puppets to carry the Sky Stone. They asked the puppets to pile the Sky Stone into pre-made metal shells. These metal shells are steel columns with different lengths. The longest one is as long as 30 kilometers. Judging from the terrifying welding traces, it took a lot of trouble to get these things. The diameters of the steel columns are different. But they are all empty inside. After the Sky Stone is put in, it forms the shape of a stone column. With the fusion talisman, the piled Sky Stones becomes a whole real stone column. After pouring the stone columns out of the metal shell, the players start to reload the Sky Stones inside. These steel columns are actually just molds, which are to quickly and accurately create beams for the ground.

Huge cities need support. Once such a large city is flying, the power it bears on its base is unimaginable. In the past, the bottom of the city was a whole piece of rock with enough strength to support these weights. But now the city is modular. The armored part not only does not bear the support force, but also consumes the power of the support system. For this reason, we need to build a strong enough support structure.

Our guild has internal support technology from the Turtle Clan. With the excellent performance of a super material such as Sky Stone, we can easily complete this support system. In fact, we have calculated that although the size of the new Aisinger after completion will be a whole circle larger than the original, the total weight is less than one-sixth of the original. Of course, this is thanks to the excellent performance of the new material.

The largest supporting beam is 30 kilometers long and the bottom is a square with a side length of 300 meters. Such a large beam is still weighing 100 tons even if the density is similar to that of foam plastic. It would be really troublesome if our company had a large number of lifting equipment!

Due to the large number of personnel and reasonable design, our construction progress was surprisingly fast. In the late night, Aisinger's bottom-floor mad frame had been completed, but now it is just a keel, and nothing except the support frame was installed. However, as long as this is completed, the speed of attaching various equipment would be much faster.

Taking advantage of the night, some huge secret equipment was transported to Aisinger, all of which came from Gangcheng. These days we built Aisinger, and the restoration of Gangcheng has been completed. New Gangcheng has not only expanded but also added equipment. In the past, the city was in a mess because it was mined and built. This time, all of them were planned through reconstruction. Now Gangcheng is basically like a factory, unlike the previous garbage dump. These new equipment is the first set of products after Gangcheng was completed.

After the equipment in the Gangchengdi area was transported to the sea, another matte came from the sea. This time the supplies came from Atlantis. After the merger of the White Sharks and Mermaids, the two tribes used the technology of the two tribes to complete the new equipment we secretly ordered. The creativity of these things came from a member of the Guild Design Bureau, but I have to admire his intelligence. In fact, this time, I have adjusted so much of the design of Isinger this time because of his novel design. Because his design will allow Isinger to have mobile capabilities, we have spent so much effort 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 fee at all.

The construction of the city is still continuing, but the technicians of our guild gathered together to assemble the super equipment transported by Atlantis and Steel City. The technicians first erected some huge roulettes, which were made of a mixture of Ink Steel and Atlantis' special alloys. Their strength is probably the highest among the equipment we are currently manufacturing, and even if it is compared with Sky Stone, it is not much different. These huge discs alone used almost 50 million crystal coins for us.

The disc was raised and then started to be assembled with other models of discs. When they formed a complete part, everyone could find that it was actually a huge wheel. The diameter of this super metal wheel reached 70 meters, which was almost as high as twenty floors. Compared with the height, these wheels were more prominent in width, and the huge wheel width reached 500 meters. It was like a roller.

These huge wheels make most of our members very strange because everyone doesn't know what this thing is for. What's even more terrifying is that there is more than one. After the first one is completed, the technicians began to direct the puppets to assemble the second and third ones. It seems that there are still many things.

At dawn, 3,200 such wheels were piled on the ground and scared those who didn't know what the hell were used for. What land are so many giant metal wheels used for? Almost everyone is speculating on this problem.

After these wheels were completed, our technicians started to work on new things. This time the thing was a huge machine, and as long as the people in our guild didn't recognize this thing, this is an ordinary gravity resistance device. However, the equipment this time is a little different. The gravity resistance device this time is much smaller than normal size, and each device seems to have more parts, but no one knows what these new parts are for.

The technician asked the puppet to make some bars with Sky Stone. The sizes and specifications of these bars are exactly the same. The length is about 50 meters, slightly wider than those wheels, about 50 meters wide, and all 8 meters thick. The bars were wrapped by the technicians with some metal items transported this time. It seems that these dimensions were planned at the beginning because the sizes of these metal wrapping layers just can fix the long board of Sky Stone. The wrapped stone slabs were swung open two times, and then the researchers placed the gravity resistance device on these special boards, which was also designed from the dimensions. The protrusions on the metal fixture were just inserted into the holes in the gravity resistance device. After putting the gravity resistance device on the board and fixing it, the researchers fixed it with another board on the device. In this way, the gravity resistance device was sandwiched between the two layers of plates.

The stone slab is relatively long. However, the resistance device is very short. One of the plates is placed on one side. The middle gap is filled with some sky stones. After the structure is completed, a layer of pre-made metal shell is wrapped on the outside. There are actually some strange devices on the shell this time, which look like a protruding probe.

When the metal parts were connected with the stone slabs of the Sky Stone, they turned into long strips with strange shapes, but everyone still couldn't see what the land was for. In the afternoon, the technicians finally began to use the strips. It was not until this time that everyone suddenly understood what it was, and they even understood the functions of those wheels.

These strips were crossed one by one, and then the connections on the metal casings could just lock each other. After the designers were busy for a whole afternoon, 400 tracks were completed. These things were exactly the same as those of tank tracks, with almost no difference except for their larger size. Everyone recognized them as tracks. However, everyone was still curious, why should the gravity resistance device be installed in these tracks?

On another sleepless night, Aisinger's construction was still in full swing. The fleet at sea brought new cargo, and the technicians directed the puppets to transport a large number of equipment to the shore. These equipment was huge and scary. Some parts were like gantry cranes at the dock, but the size was even larger. The supplies unloaded overnight were quickly used.

First, the technicians spread a track flat on the ground, and then they made 8 large wheels. I directed Lucky and Plague to help connect some strange-shaped equipment. After completion, these equipment looked like the type of large diesel engine used on luxury yachts, but the size was particularly huge. These equipment that looked like engines were actually engines, but they were not diesel-burning ground, but were powered by magic crystals.

The researchers directed the puppet to connect eight metal support frames with the same letters as y, and then we connected the power equipment. The eight inverted y-type brackets were just mounted on the bearings of eight wheels. The transmission shaft on the power equipment was then connected to the support frame. This inverted y-type support is not only a support, but also a transmission equipment. After all these were completed, the researchers passed the track through the wheels and clenched them.

Now if anyone can't tell what this is, it's unreasonable. This thing is completely a track propulsion device. The only special thing is that there is a gravity resistance device in the track clamp.

The researchers assembled the remaining parts in this way. After all 400 track propulsion devices were completed, they were very spectacular. The huge tracks and those brackets were simply mobile buildings.

These are still not finished. The third hooded equipment has finally arrived. The number of things shipped this time is small, but the volume is even larger. What we see is a jack-like equipment, of course, much larger. There are 401 jack-like equipment in total. Among them, 400 are exactly the same, and only one is particularly large.

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

These jack-like large equipment are reversed and connected to those crawler thrusters, and the thick metal support columns extending from the "jack" can be inserted into the fixtures on the support frames. The functions of these jack equipment are very simple, they can extend or shorten the metal support columns, and in addition they can rotate. There are only two functions.

When these devices were installed, everyone understood their purpose more clearly. In everyone's excited eyes, the researchers finally came back to install the devices. But instead of moving the crawlers, they brought the largest jack to the top.

The largest "jack" has a strange shape. It looks like two jacks connecting the central support column together, which means it looks like two head-to-head jacks.

The researcher asked the dragon to bring it to the center of the city. Originally, those who were in charge of the construction did not understand why the frame was first built with the sky stone when building the urban frame. Now he finally understood the reason. This super jack is as high as 800 meters, and if the frame was not built in advance, it would not have been installed in at all.

The jack was placed in the center of the city, and then some people climbed up to manually operate the jack to extend, and it stopped until the upper jack was pressed on the beam. The construction staff began to fix the jack on top. Using the parts transported with the jack, everyone quickly connected it to the city frame.

The researchers first experimented with the shrinking jack. Because the top and the frame were connected, the bottom naturally left the ground. After confirming that it would not loosen, the researchers extended it out and lifted the city frame. Then they ordered the temporary support to be removed. After all the temporary support was removed, the city was completely supported by the jack.
Chapter completed!
