Chapter 374: Searching for Minerals (Please vote and subscribe)
After Luo Chong's analysis, it is certain that there are minerals there, and they are crystal minerals, but it is unknown whether they are metal or quartz. However, he is more inclined to believe that there are crystals there.
Because the piezoelectric effect produced by high-purity crystals will be greater, and Youye also explained in the letter that bright flashes appeared in the cracks, which is easy to understand. Assuming that there is a crystal mine below, it is normal for these crystals to discharge again under violent vibration and compression. Therefore, as long as there are a large number of electric sparks flowing in the crystal, it is not impossible for those transparent crystals to refract the electric light infinitely and finally illuminate the entire vein.
On the contrary, if it is an opaque quartz or metal vein, then the possibility of them producing flashes is extremely small.
Although crystal is not a metal vein, it is still very useful. The main component of pure transparent crystal is silicon dioxide. Depending on the transparency, its purity is also different, but the cleanest crystal basically has 99.999% silicon dioxide content, which is the best material for making special glass, or in other words, it is originally a super clean glass.
As for why it is called special glass, it is because the glass made of crystal not only has good light transmittance, suitable for making various optical instruments, but also has the characteristics of high temperature resistance. It is also often used to make various containers, especially laboratory utensils, such as beakers, thermometers and the like.
The melting point of traditional ordinary glass is between 500 and 600 degrees, but the melting point of crystal glass is about 1,200 degrees, which is directly doubled. Although it is more difficult to make, it also has its own advantages.
Ordinary glass requires a lot of catalysts to be added due to its impure composition, such as carbon, soda ash, etc., but crystal glass does not need it, because it is originally a piece of natural "glass", so the processing method of crystal glass is like "melting directly and plasticizing again". It can be said that as long as the temperature is high enough, basically no additional catalyst is needed. However, this is not a big problem for the Han tribe that can already smelt copper and iron.
But the biggest problem now is that it is still unclear whether it is a crystal mine, because all this is just Luo Chong's guess.
After figuring out the key, Luo Chong immediately wrote a letter back to Youye. In the letter, he first expressed his grief for the sacrificed team members and said that he would take good care of their families and let Youye and others bury the dead on the spot. Then he mainly explained that there were no gods or demons in the mountain, but there was a crystal mine. The strange phenomenon of the mountain shaking and rising and falling was also caused by lightning hitting the crystal stone. He asked Youye and others not to be afraid.
Secondly, under the condition of ensuring safety, it is best to explore deep into the cave to see if you can find one or two crystal stones to take back as samples, and then continue to scout, and be sure to find the gathering place of the cannibals.
Finally, Luo Chong asked Youye in the letter if he needed any supplies. Of course, it could only be things that were not too heavy, so that he could let the giant eagle deliver it directly to him.
The letter was sent out that night. The giant eagle has a strong night vision ability, and they have lived near the floating island for a long time. They are also very sensitive to geomagnetism, that is, they have a good sense of direction. This is why Luo Chong dared to let them deliver letters at night.
The next morning after the letter was sent, Youye received a reply from Luo Chong, which made the surviving members of the entire team breathe a sigh of relief. This at least proved that they could still contact the tribe. Although they were thousands of miles away, they still felt that the entire tribe was supporting them and they were not fighting alone.
This feeling was very good, especially for a group of people who had just experienced a disaster. Nothing was more frightening than fear and loneliness.
Youye quickly read Luo Chong's reply and told the other team members. When they heard that the leader judged that it was a crystal mine, everyone was relieved. Although they didn't know what a crystal mine was, Youye knew the word mine. The copper and iron tools they used were all extracted from the mine. To put it bluntly, it was just a pile of stones, a pile of dead things.
Fear comes from the unknown, but when they learned the truth of the matter, they naturally stopped being afraid. Compared with the monsters that they didn't know what they would look like, and the gods that they couldn't see or touch, if it was just a pile of stones, what would be scary.
"Captain, do we still need to go into the cave to have a look? The leader asked us to go in and look for stones?" The Eagle Clan member asked.
"Yes, the leader said so, so of course we have to go in and look for it." Youye said with a relaxed look. After reading Luo Chong's reply, he was no longer afraid. He just went in to find two stones. As long as there was no thunder again, there was nothing to be afraid of.
"But don't we have a mine? Why do we need to find another one? And we don't even know what that stone looks like. There are so many stones in the cave, how can we know which one it is?" The Eagle Clan member asked again, still seeming to be frightened by the experience last night, and not so willing to enter the cave.
"Why do you have such an idea? Don't you know how important ore is to our Han tribe? Without copper and iron, can we live such a good life now? Without those metal tools, can we grow so much food? Without the metal weapons in your hands, can we protect our families from being killed by cannibals?" Youye blurted out a series of rhetorical questions, strongly expressing his displeasure.
"You should be happy that you can find new ores for the tribe this time. If these new ores can make better things, it will be good for the whole tribe. And as long as we can bring the ores back, we will definitely be rewarded by the leader. In the future, in front of the tribe, you will also be meritorious people. Don't you want that?" Youye looked at them without saying anything, calmed down, and encouraged them again.
"I didn't say I didn't want to look for it. It's just that I don't know what that kind of stone looks like." The Eagle Clan member who was scolded muttered in a low voice, unwilling to admit that he was timid.
"This problem is easy to solve. Since the leader said it was ore, it must be different from the ordinary stones we have seen. We just need to take one piece of each of those stones that look different. There will always be one that the leader needs. When the time comes, we can bring it back to the leader to see it." Youye made a decision immediately.
"Okay, when are we going to go in and look for stones?"
"Of course as soon as possible, but you don't have to worry. You don't have to go in this time. Leave a few people outside to guard the camp. Just keep an eye on our horses. I will only take two people, a total of three people, in. Even if there is danger, we don't have to go in." Youye said firmly.
