Of course, walls and roofs need materials that are lightweight, strong, and preferably resistant to high temperatures and acids and alkalis. On earth such materials are expensive and difficult to obtain by age, and on the continent of this world it is a problem, but on the island of Remiret - it is an easy problem to solve. The monsters on the island have access to many of these large materials, and the carapaces of these arthropods are basically very suitable for these requirements, and the best thing is that Remilet Island also produces a large number of extra-large arthropods - such as the sickle crab and shield crab that can be found everywhere in the volcanic terrain or on the seaside, and the carapace of these large hermit crabs that is more than one person tall and the "shell" they find are one of the best materials. Of course, if you can catch the boss-level big guy, then the carapace on one head is enough to lay a large piece of wall or roof.

In fact, this is also a major export volume of Remiret, and the deep sea port has made its fortune by doing this kind of import and export trade, and the outer side of their city is originally a rocky beach rich in such things, and the really huge and excellent quality are all produced in the black tower. The dragons were interested in hunting these crabs - one of the largest hobbyist groups of the dragonmen were the hunters, who saw hunting as their life, and most of the fruits of the hunt, except for a small part of them as decorative trophies, were not worth mentioning to them at all, and handed them over to the elders of the clan to trade with humans.

Now as the Great Elder, Zhou Zhongmou issued his own hunting bounty, so a large number of dragons began to hunt the Daimyo Shield Crab and the Daimyo Sickle Crab, and of course, there were also weevil kings and crystal scorpion kings. The steel structure is now almost complete, and there is a long metal slide gantry crane more than 30 meters from the ground. The length of the entire steel structure is more than 200 meters. The width reached a hundred meters. With a height of nearly fifty meters, the strength of steel added by rare minerals is sufficient to support such a structure. It is also quite exaggerated that such a factory is placed on the mainland, and it can even be said to be the only one. Many people come to see this architectural marvel every day, and it is true that just this one building makes some people change their mindset: "Maybe they can really build something?"

Collecting these carapaces is quite fast, after all, except for the Scorpion King, these arthropods are not powerful boss-level monsters. The dragons are extremely experienced and combative hunters, and of course they have completed all the tasks in just one week. There was a large pile of carapaces outside the factory. The dragons, who specialize in alchemy, will try to soften these carapaces, then reshape them, and finally put them together piece by piece after post-processing. The carapace was soaked in the prey's own bodily fluids, then some blood from other monsters or something, and finally some strange ores and monster crystals. Then Zhou Zhongmou watched as the large chunk of hard carapace softened like this, turning into a flat plate like resin. The dragons then began to trim the shape, and after calculation, the trimmed carapace was laid flat on the stone slab and coated with a liquid made with herbs. Then Zhou Zhongmou watched as these things began to harden - the specific expression was that the surface began to become smooth and reflective, and the luster of metal appeared on these carapaces. Finally, the grease extracted from the monster's body is applied, and a large piece of spliced material is completed.

As for spelling it up. The dragonmen also had their own unique secret method - using the body fluids squeezed out of a specialized insect as glue, and it really seemed to make a model to put the factory together. "It took three days to process the material. As a result, the stitching only takes a day to complete? Zhou Zhongmou was amazed, of course, there were a lot of things that could be compared to him in the real room now, and artificial muscles were only a part of them. Now this guy is holding a fleshy tentacle in his hand, and a lot of suckers have grown on the tentacles where he grasps, and the suckers are attached to the palm, and then this tentacle moves by Zhou Zhongmou's mind - "It feels like I have grown a tentacle myself, and I even have a sense of touch and cold and heat" This is another real product he just made. Of course, the inspiration came from the prosthetic limbs made by a certain dragon clan - this guy helps hunters who have been injured and lost limbs to use the organ structure of monsters to make prosthetic limbs, and the flexibility is no different from the original limbs of the injured person, and it can also control the prosthetic limbs partially like his own hands and feet - so this thing is expensive, of course, mainly because the materials are relatively rare.

The factory was completed five months after Zhou Zhongmou proposed to build it. But there was nothing in it, except for the gantry crane on the top, a corner of the factory building was an improved blast furnace, and then other than that, there were some shelves or something. "It seems that we have a lot of work to do," Zhou Zhongmou said, and those spies had already passed the news back, of course, the kingdom of Novaya Zemlya was completely relieved, and it was impossible for Remiret Island to build land warships in the foreseeable years.

In fact, it is really quite difficult to build a land warship, although Zhou Zhongmou has successfully developed the artifact of the three-rise steam engine, but he still has no clue about the gun barrel or something, if he builds an unarmed land ship, it is estimated that there is a way - as long as he continues to study and solve the suspension problem. Zhou Zhongmou didn't know much about the suspension of the land battleship, because there could be no design drawings in the information obtained, and no actual finished product had been seen by him. However, judging from the pictures he had seen, the small land warships in the Duchy of Belken, that is, the thousand-ton ones, should have been suspended by torsion bars, which of course could be concluded from the staggered load wheels. "Although Belken said that this country is based on Sandezi as a prototype, but I didn't expect that this thing developed is really as keen on using torsion bar suspension with cross-load wheels as Sandezi" This guy thought with a smile, "I really sympathize with those soldiers, the difficulty and complexity of this maintenance is a nightmare." "Of course, Zhou Zhongmou is using the concept of the earth again, in fact, this world has unscientific magic alchemy technology, and the strength of those torsion bars is much stronger than similar ones on the earth - not to mention the anti-gravity magic array.

Just as Zhou Zhongmou slowly began to gradually manufacture hydraulic presses and large lathes according to the concept of the earth, the kingdom of Novaya Zemlya finally came up with a way to transport land warships to Remiret. (To be continued......)
