The fleet continued westward, flying for a total of eleven hours, and saw fire on the ground at three o'clock in the morning.
This fire was the camping site of two teams of our own exploration expedition team. There was also light outside the camp, a take-off and landing line composed of small light bulbs.
After the fleet communicated through lights, the two aircraft dived to lower their altitude and circled. Wang Qi's plane activated the deceleration flight mode and circled down.
The deceleration flight mode is achieved by separating the flaps. Normally it looks like just a small piece of the wing. When decelerating, it separates up and down, creating a speedbrake-like effect. The wooden man flies originally slowly. Even if it hovers and descends after deceleration, the speed will not exceed 120 kilometers.
Lower to the take-off and landing height, continue to decelerate, and approach and land at a speed of 70 kilometers per hour.
The plane was light, and although it was not a professional airport, it only bounced slightly before landing smoothly.
The escort fleet also fell down one by one.
Overall the flying experience was weird.
The takeoff is a vertical takeoff, with frequent lifts and landings during the flight. However, the kinetic energy cannot be eliminated through magic during landing, and it turns into a normal rolling landing.
The pilot needs to rest. Although everyone has some night vision ability, the field of vision cannot be compared with that during the day. Wang Qi went down to say hello to everyone, but still rested on the plane and waited for dawn.
As the sun rises, the high ground where the small camp is located has a good view, and we can already see the color of the water on the horizon.
The pilot was still resting, while Wang Qi listened to the exploration team's report.
"This plate covers an area of about 14,000 square kilometers. There are only two fishing villages. Now most of them have migrated to more populated areas. Surface copper enrichment was found near the boundary of the Eastern District. There should be copper mines underground. This point on the coastline There are lithium deposits and as the shoreline recedes, our sampling in areas of the coral bed shows there may be oil underneath."
"Is it impossible to estimate the range of reserves?" Wang Qi asked.
"Your Majesty, these mines are more than a hundred meters away from the surface. We can't get big equipment here. We can only do shallow sampling with the accompanying tools, and we don't know the geological conditions below."
It is difficult to say whether the location of the land belongs to the Ongi Kingdom. The current point is about 1,200 kilometers away from the Bathtub Sea where the Luna River flows into. Due to the lack of fresh water, only scattered villages have settled, and there are no cities further north. .
Geological exploration is a matter that can easily cause conflicts. The exploration team came here because Wengji's population and control in this direction are basically negligible.
Wang Qi will pay attention to this place because of the copper mine.
Copper is very difficult to smelt. Like tin and lead, they are all metals that can be obtained directly from campfires before the emergence of iron tools.
The kingdoms and empires in the penal colony used it as currency, so it should be relatively scarce.
The ease of smelting and the scarcity of ore veins determine that similar shallower ownerless copper veins are very difficult to find.
But copper is very important. Whether it is the electrical conductivity second only to silver or its thermal conductivity exceeding 400w/m·k at room temperature (more than ten times that of stainless steel), it is an excellent industrial raw material that is difficult to replace.
The kingdom has no copper mines and relies entirely on recycling copper from copper coins. Not only is the cost high, but the quantity is also insufficient. As a result, the current power grid in the kingdom is mainly made of aluminum-iron alloy wires. Even some motors are not copper wires, which has a high chance of burning out. bigger.
So when he heard that there might be a copper mine some time ago, he decided to ask Li Xiang to come and take a look. However, because of the discoveries of lithium, oil, and the retreat of the coastline, he decided to come together.
"The copper mine is very important to the kingdom. Let's go take a look after everyone has had breakfast. Maybe the special envoy can help you take a sample."
"yes!"
The joy of the reporting team members was beyond words. Their unit had contact with His Highness Li Xiang, but the chance was slim. Who wouldn't want to see the majesty of the Valkyrie up close?
After everyone had breakfast, a team was left to take care of and protect the pilots. Wang Qi, Li Xiang and other six people followed another team to see if there was any hope of finding a copper mine.
After walking a few kilometers from the camp to the target area, there was no green, just bare rocks.
This kind of scene is very common at the seaside. Affected by the perennial sea breeze, the coastline is basically saline-alkali land, which is not conducive to the growth of natural plants. The green mentioned here is the green unique to copper mines.
There is no patina, that is, there is no characteristic sign. The fact that copper accumulation can be found here shows that the exploration team dug holes very diligently.
"In this area, we drilled holes every 100 meters and found that three of the six samples were rich in copper. This is the one with the highest concentration."
The hole in front of everyone is only about eight centimeters in diameter. It was drilled with a special manual drilling tool. The team members still have the same tool with them, some long and some short.
Wang Qi looked at Li Xiang: "Can you try it?"
"Just give it a try. Just stay back."
Wang Qi and others gave way.
Li Xiang came out without any armor. It was still not good to hit him directly with his fist, so he used magic first.
First there is an earthquake.
Earthquake is a four-ring magic, which is said to be very suitable for use on the battlefield. This was the first four-ring magic she learned, and it didn't take long for her to learn it.
The destructive power of the earthquake I just learned is a bit of a mystery. There are a few small lines on the ground, but it's nothing serious.
The real sampling method depends on the third-level spell, Earth Thorn.
Like Earthquake, Ground Thorn is a tactical magic that is rarely used in mage fights. However, if it is cast continuously on the battlefield, even if it does not cause direct damage, it can build temporary fortifications and give one's side a local advantage.
Generally, when mages use ground thorns, they will try to use them in soil, mudstone, and sandstone terrain. The stones here are igneous rocks that are similar to granite, which will consume particularly magic power.
But it doesn't matter, Li thinks there are hundreds of such mysterious spells. Even though it has a lot of magic power, and the earthquake was used to loosen the muscles and bones, it doesn't cost much to cast the spell directly.
Her control over the three-ring magic was obviously better. The ground thorns sprang out directly from the hole drilled by the exploration team and stopped at a height of more than three meters.
Then he kicked it off and let it go again.
Magic below the fifth ring does not involve creation out of thin air, and the same is certainly true of ground thorns. These ground thorns are actually underground rock masses, but their shapes have been reconstructed.
Continuously generating ground thorns and kicking them off. Due to the relationship between control and underground holes, it is inevitable that the holes will become larger and larger, and the ground thorns behind will become thicker and thicker. After kicking about twenty thorns, they will be broken. The bottom diameter of the ground thorn has exceeded thirty centimeters.
She stopped suddenly and stared at the one that was finally kicked off: "Is this a mine?"
The exploration team members hurried forward, and Wang Qi followed behind, but first glanced at the section that was broken by the kick and connected to the ground.
There is no hole, just like an ordinary rock section. There is a cavity probably dozens of miles down.
Looking at the stone thorn she pointed at, there were a little yellow and green spots on the back half.
I quickly received a positive answer: "Yes, Your Majesty, Your Highness, this is copper ore, chalcopyrite, with a high sulfur content."
Tsk!
Wang Qi didn't make a sound, but he was very disgusted.
High sulfur content means that a more complicated desulfurization process is required, or like the pyrite produced in underground cities, it is first used to make sulfuric acid, and then the slag is used to find a way to extract the metal.
"Special envoy, let's take a look at two more."
Li Xiang gave him a look, waved away the exploration team, and took a few more cigarettes.
