Wei Xuan looked at it and couldn't help but be happy. Pen, fun, pavilion www. biquge。 info He had expected Gneuth to ask for gold or silver, but he didn't expect that Gneus would only ask for pure copper. On Earth, the price of copper is not cheap, but it is still much worse than precious metals such as gold, silver, and platinum.

Of course, Wei Xuan has a strong sense of hometown, and he is not willing to do it if he can transport the resources of other worlds to the earth, but he is not willing to do it at a loss if he transports the resources of the earth to other worlds. Because matter is a balance, a little bit of resources will be used less.

Wei Xuan rubbed the piece of pure copper in his hand and asked, "Is this thing valuable?"

"It's very rare, but it's essential to make certain equipment, so it's valuable," Gneuth said. ”

It's just rare, it's not that there isn't, and that's easy to do. Wei Xuan nodded and said, "Okay, if I can help you find a copper mine, will there be anything to say from the council?"

Gneus patted his chest and said, "Absolutely no problem! I'll go to the council!"

Seeing Gneus leaving, the succubus was puzzled: "You can control those generals, why don't you control those councilors, wouldn't it be easy." ”

Wei Xuan said with a smile: "There are only a few generals, but there are more than 1,600 parliamentarians. For an issue to pass in Parliament, it needs at least two-thirds of the people in favour. Controlling thousands of people at the same time, even if my brain is enough, the quarrel is killed by them, and it is convenient to directly exchange benefits. ”

The succubus was curious, "Then where are you going to find copper ore?"

Wei Xuan pointed to his head and said, "Divine sense." Don't forget, my sense is much stronger than yours. As long as there are suitable copper mines in the Haya Empire, I can find them. ”

Feng Wu pouted and said, "I don't believe it! If you have this ability, if you want to find a spirit stone mine, you can just open your divine consciousness yourself, why do you need to fake the little demons and those cultivators?"

Wei Xuan smiled bitterly: "If the divine sense can find the spirit stone mine, why do I need to be so troublesome." Perhaps because the spirit stone contains aura, it also has spirituality and knows how to avoid divine consciousness. Forget it, let's not mention the matter of the spirit stone for the time being, you help me protect the Fa, and I'll see where there is a copper mine first. ”

......

The composition of different worlds is inseparable from various atoms, and the difference between them lies only in the content of different atoms. For example, gold is very rare on Earth, and iridium mostly comes from meteorites. But on some planets, the gold content even exceeds 50 percent. The same is true for the Ground Dog world, where copper is rare.

Wei Xuan really paid little attention to the composition of a planet, because he was now a practitioner, not a physicist or chemist. But this time, in order to obtain the top technology of the Haya Empire, he can only do some exploration.

As his consciousness unfolded little by little, Wei Xuan discovered that the Earth Dog World had similarities with the Earth, with a large amount of earth on the surface and granite and limestone underneath the soil. But compared to the earth, not only is copper ore very scarce, but gold, silver, iron, and tin are also pitifully scarce. Perhaps copper had a more important special use in the technology of the Haya Empire, so it was more valued, so that Gneus solemnly put the pure copper in the safe and put it forward as a condition.

In fact, as long as you go deep into the center of the earth, under the hot magma, there is a large amount of molten into a liquid metal, mainly iron, but also gold, silver, copper, tin, and so on. However, with the current level of science and technology of the Haya Empire, it is not capable of mining at all, so it has no value.

Wei Xuan's divine sense swept inch by inch on the land of the Haya Empire, and he really discovered more than a dozen mineral deposits, including copper ore, iron ore, and a variety of metal symbiotic ores, but the reserves were very limited, ranging from a few tons to a dozen tons. This also reflects from one side how scarce the metal is here.

Suddenly, Wei Xuan's brow furrowed, and his fingers were a little heavier on the map.

Feng Wu asked in surprise, "What's wrong?"

Wei Xuan smiled: "Finally found a big guy." ”

It is a copper mine, with a storage capacity of nearly 1,000 tons, which is definitely a big mine in the Digou world, and it is very shallow and can be mined under more than ten meters of topsoil. With this discovery, Wei Xuan can be regarded as worthy of the technology of the Haya Empire.

The succubus said, "It seems to be out of the borders of the Haya Empire." ”

Wei Xuan took a closer look and said with a smile: "Not all of them are out of bounds, and a small half of them are in the territory of the Haya Empire." Okay, that's it, it's okay. As for how much the Haya Empire can mine, that's not our concern. ”

......

With Wei Xuan's guidance, the geological exploration team of the Haya Empire only took one day to find the copper mine smoothly. When the news came back, the whole country rejoiced.

Gneus didn't break his promise, and came to Wei Xuan with a thick stack of materials, saying, "The information about power and lasers is all here. ”

It turns out that, unlike the earth, the Haya Empire uses not lithium batteries, but calcium batteries. All kinds of metals are very scarce in the ground dog world, so there is no ability to develop other metal products. Many times, people's imagination and creativity are forced out by the environment. Due to the lack of other metals, many of the technologies in the Ground Dog world revolve around more readily available granite and limestone.

The main component of limestone is calcium carbonate, and the main component of granite is quartz. The Haya people found a way to produce a calcium-silicon compound from granite and limestone under certain conditions. Batteries made from this calcium-silicon compound can store a large amount of electrical energy in a very small volume.

The calcium-silicon cell used in the radio gun is less than half the size of the No. 7 battery, but it can fire a hundred powerful arcs. The energy required for laser weapons to be used in actual combat is very huge, and it is precisely with this high-energy battery that the application of laser weapons is possible. As for the laser weapons themselves, in terms of technology, they are no more advanced than the Earth.

Because of the lack of copper and iron, the most used metal material in the ground dog world is a complex calcium-aluminum alloy. From aircraft, vehicles, and ships to firearms parts and cups, they are all inseparable from calcium and aluminum alloys. However, the performance of this calcium-aluminum alloy in all aspects is not half a star worse than that of the alloy on the earth, which is why everyone is required to carry a parachute on their backs before the forced landing of the passenger plane. But for the ground dog world, there is no way to use calcium aluminum alloy.

Wei Xuan glanced at ten lines and quickly read all the information.

He graduated from the Department of Physics, and has been engaged in popular science work for many years, coupled with the support of a strong divine sense, it is not difficult to understand the content recorded in the materials. Among the so-called cutting-edge technologies of the Haya Empire, the only thing that really aroused Wei Xuan's interest was the calcium-silicon battery.

Wei Xuan pulled out the part of the information about the calcium-silicon battery, glanced at Gneus, and suddenly said coldly: "You are not very honest. ”
