From Douluo Dalu to Queen

Chapter 380 Carbon Coating
Soon, the scan was completed, and a list of mineral requirements appeared on it.

The minerals on this list are all the most basic minerals, such as iron, tin, copper, carbon, etc. During the manufacturing process, they will be automatically refined into steel with the strength shown in the drawings. This does not require any technical content.

Minerals like tungsten, chromium, aluminum, and diamond, which are common on Earth but relatively rare on Douluo Continent, can actually be replaced by corresponding substitutes. Flanders collected a lot of these minerals for her, and the output is not rare. In other words, they are actually the same thing, just with different names.

Flanders spent nearly 100 million gold soul coins on various kinds of metals. If they were piled up, dozens of large warehouses would not be able to hold them. Nishizumi Miho said that these basic minerals would be refined into the standard tank armor material of the Tank Track Association, which would shrink by about ten times, and that did not include the carbon coating on the outside.

The price of minerals in Douluo Continent is actually not much different from that on Earth. One hundred million gold soul coins worth of minerals can build about 10,000 main battle tanks.

Leng Xiyao did not plan to use all of these minerals to build chariots. Building 5,000 chariots would be terrifying enough, and she wanted to keep the rest to prepare for building large ships in the future.

However, Leng Xiyao does not have so many minerals at the moment. Most of them have to wait for subsequent sellers to ship them over. Now the minerals she has are only enough to build about 100 units.

The cards are interconnected. Leng Xiyao directly threw the card containing the minerals in. After a few seconds, the forging card popped out the storage card. The resources inside were all there except for those needed for manufacturing.

With enough resources, a three-hour countdown will appear on the forging card, which should be the manufacturing time.

After arranging the manufacturing, Leng Xiyao extracted the part about carbon coating from Drawing No. 4.

The carbon coating is mainly composed of graphite, and is mixed with carbon-containing materials such as diamond, fullerene, and carbine. The condensed product is similar to paint and needs to be applied to all parts of the tank when used. These coatings have the characteristics of light weight, porosity, conductivity, thermal conductivity, corrosion resistance, lubricity, high temperature strength, heat resistance, heat shock resistance, immunity to radiation, low thermal expansion, low elasticity, and cold resistance. It is equivalent to adding a domineering effect to the armor, making the vehicle body lighter and increasing the speed, and can offset a large amount of damage from small-yield missiles, high-explosive bombs, individual rockets, mines, strong acid, lightning, and lava, or simply make it immune.

Even if the outer coating is worn away by artillery bombardment, the crew can apply the spare coating again in just a few tens of seconds, and the attack and defense costs differ by nearly a hundred times.

The only thing that can be of some use to it is a missile with an armor-piercing warhead or a nuclear bomb.

The manufacturing cost of these two weapons is much higher than that of carbon coating. Moreover, the armor of the tank itself is of extremely high quality. Being able to break the carbon coating does not necessarily mean being able to penetrate the armor. Only when the nuclear bomb explodes at close range can it have a stable output. If it is too far away, the shock wave and radiation will not cause any damage to it.

It is precisely because of this incredible black technology that the major college factions were able to quickly and peacefully unify to form the Tank Road Alliance - after all, everyone has the strongest shield but no suitable spear. Even if a fight really breaks out and an armored duel occurs on the battlefield, they will just scrape each other as a sign of friendship and then break through the equally scraped defense line to launch a sneak attack on the base camp. If everyone is looting, isn't that the same as not looting?
An effective armor-piercing missile is much more expensive than a tank. With the money, it is better to build more tanks. At least if you scrape too much, you can kill people.

Since this is the outcome of a war anyway, it would be better not to fight. Wouldn't it be reasonable to decide the leader through a tank race?
The root of all this is that carbon coating is too cheap.

As the name suggests, the core of carbon coating is carbon. Of course, it is not the coal for burning, but the carbon element.

The element carbon is actually not uncommon. The main source is graphite ore. The output of graphite in Douluo Continent is not small, but its status is very low. It is even worse than ordinary materials such as clay, and very few people use it - because it can't even be used to build houses and can't be used for burning fires.

Precisely because they were too cheap and had little value, Leng Xiyao didn't collect too many. According to the manufacturing standards of forging cards, she could only make two at most.

No one knows the value of this thing. In fact, Leng Xiyao only has a vague understanding of it. She also doesn't know the specific reaction principle. In short, high-purity carbon elements are extracted from graphite, and then undergo a series of chemical reactions to become a carbon coating.

The manufacturing process of the Tank Road Alliance has not yet reached its peak. Due to the limitation of the technological level, the carbon elements they extract are not pure enough. In order to maintain the quality, they must be mixed with other materials as auxiliary materials. However, the Forging Card does not need this at all. The blueprint stipulates how much carbon elements are needed to make a carbon coating for such a tank. Then the Forging Card only needs the most basic graphite to refine the carbon coating. In terms of the process of individual materials, they will not follow the ratio on the blueprint, but have their own advanced smelting process. In other words, even the most basic steelmaking process will be more perfect, saving materials while producing the same quality of the tanks.

The same is probably true for the assembly lines in the interstellar age. Such an advanced industrial system combined with this black technology will surely greatly meet her needs.

Three hours was neither long nor short, and she didn’t have to worry about anything going on outside, so she simply sat on the bed and started practicing, and the time passed in a flash.

When the time came, Leng Xiyao couldn't wait to take out the forging card and take a look. After the construction was completed, the forging card was no different from an ordinary storage card. There was a brand new Type 4 tank in it, which was exactly the same as the one on the drawing, even the position of the anglerfish pattern was exactly the same.

Before summoning it, she could see the components inside, such as the engine, radio and basic ammunition. Although they were all antiques and there was currently no corresponding system, this was enough to prove how powerful the forging card was.

"Amazing, so amazing." Leng Xiyao exclaimed in amazement, then put it away.

After having a quick lunch, she prepared to go check on Miho Nishizumi.

Although there are many soul masters who can cause such damage, the artillery salvo is undoubtedly more shocking, especially these artillery and shells that are strengthened by psychic energy. One shot can destroy a small building. The deterrent power of ten cannons firing continuously is still terrifying.

The artillery position chosen by Nishizumi Miho was in a square not far away. With the assistance of the Spirit Hall Guards, the place had already been cleared, but many curious people came to watch, basically all of them were civilians.
