The Invasion of Mysterious City

　　"Okay, can your mining speed be comparable to an engineering robot? Don't waste time and leave quickly."

　　"This……!"

　　These slaves really wanted to repay their gratitude. The only thing they knew was mining ore, but when Xiao Ran said this, they didn't know what to do.

　　"Okay, let's go. You don't need your help here. It won't take long for the entire planet to become a ruined place. Before that, you should leave quickly and find your own new home." Luo Xue said.

　　"Leave this planet and start a new life of your own," Yuxin said.

　　"You heard it clearly, hurry up and don't waste time here." Xiao Ran said.

　　"We get it."

　　I heard Xiao Ran and the others said that the slaves were a little lost. I didn’t expect that they would not be able to help at all, but after cleaning up, these slaves also returned to their steel cities to pack their things. In fact, there was nothing to pack, that is, some memorable things to take away.

　　A total of [-] million slaves from the entire planet, led by an old slave, went to the planet's arsenal and left the planet in a spaceship, but the number of people was a bit large, and a standard spaceship of [-] people was hard inside. It crowded tens of thousands of people, and fortunately, the spacecraft has an automatic navigation function, otherwise they would not be able to leave the natives who can't drive a spacecraft.

　　These slaves of various races sailed to the long universe to find their new home. After a few years, they even developed into an intermediate cosmic civilization and had a certain status in the entire universe. At the same time, the federation formed by these slaves also completely abolished the slave system. , does not allow the existence of any slaves.

　　Of course, these are all later stories...!

　　"The masters and slaves have all left' ~." Zero Zero Seven reported.

　　"That's good."

　　Xiao Ran doesn't care about the slave thing. It is the mineral resources of this planet that Xiao Ran pays attention to. Fortunately, most of the mineral resources of the planet have been marked and discovered, and it only needs engineering robots to mine.

　　...!

　　"Big brother...!"

　　At the same time, Zhou Yi, who had successfully searched the entire cosmos docking port, also entered the planet in a spaceship and came to Xiao Ran and the others.

　　"All the mineral resources are in it, and I estimate the value should be in the range of tens of billions to hundreds of billions." Zhou Yi said.

　　"That high?"

　　"Well! Many of these are rare and high-grade ores, and the imperial army also collects them in large quantities."

　　"It's good to sell these first."

　　Without a word, Xiao Ran opened the army's point exchange and sales system to sell all the ores.

　　"Drip!"

　　"Is all kinds of rare ores worth billions of tons worth [-] billion points sold?"

　　"so many?"

　　Xiao Ran was a little stunned when he saw the price displayed above. Although Zhou Yi said that the value was not low, Xiao Ran felt that it would be good to have tens of billions of these ores. He didn’t expect it to be so high. After a closer look, it turned out that one of them was only [-] million tons. [-] million tons of blue gold source ore sold for [-] billion points, and this [-] million tons accounted for half of the points.

　　"Blue gold source ore is one of the core ore used to manufacture imperial starships and technological weapons."

　　"That's why it's so expensive."

　　Xiao Ran didn't know much about ore, but after reading the introduction of Blue Gold Source ore, he understood why only [-] million tons of ore was so expensive.

　　"How many veins of blue gold source are there on the planet."

　　Now that he knew which ore was the most expensive, Xiao Ran naturally had to increase his efforts to mine that ore first.

　　"There are thirty-two veins in the master planet's blue gold source. The place where it is located is geologically hard, so the slave miners can't mine much in one year. The [-] million tons are only obtained after twenty years of mining."

　　"' "Hehe! Of course those slaves can't be mined, but it's different with engineering robots."

　　"What grade of ore veins are those thirty-two?" Zhou Yi asked.

　　"There is only one high-level ore vein, four intermediate-level ore veins, and the rest are primary blue gold source ore veins." Zero Zero Seven said.

　　"Send it."

　　"I'm afraid the value of those mined by Big Brother is at least a few trillion points." Zhou Yi said excitedly.

　　"I didn't expect this planet to have such a treasured ore vein." Mu Fei said.

　　"awesome."

　　"We were lucky."

　　Xiao Ran’s luck can’t be said to be good, it’s totally amazing. This resource planet has a lot of special and rare ores, and it is also one of the top large resource planets in the entire Silver Dragon Empire. The rest of the resource planets are completely incomparable.

　　"Drip!"

　　Xiao Ran exchanged [-] million working robots in one go to go to the location of thirty-two blue gold source ore veins. At the same time, Zha (Wang Zhaozhao) took a look at the second most valuable ore vein. Jinwu mother ore is also a rare and useful ore. The empire is also in great demand for large ores. Although it is not as good as the blue gold source ores, it is relatively high compared to other ores.

　　"Focus on mining these two kinds of ores first." Xiao Ran gave orders to the engineering robot.

　　"Yes, sir."

　　"The value of these two kinds of ores occupies more than half of the entire planet. After mining these two kinds of ores, we will go to the next planet." Xiao Ran said to several people.

　　Xiao Ran is now focusing on rare resources with high value, and those resources that usually need to be exchanged for points are simply abandoned by Xiao Ran.

　　"Listen to brother."

　　"I didn't expect to discover rare mineral resources by mining the first resource planet," said Mu Fei.

　　"Brother will buy me a dragon egg after mining those ore." Xiyan said.

　　"OK, no problem."

　　...! .

Chapter 411

　　At first, Xiao Ran thought that even if it was a planet's mineral resources, because it is a planet with a primary cosmic civilization, it would definitely not have any rare resources. It is not bad to be able to mine the entire planet and exchange it for tens of billions. However, rare ores were discovered on this planet. The value of rare ores in dozens of veins was no less than tens of trillions of points. Xiao Ran was in a good mood.

　　"The master has collected all the ores in all the warehouses on the entire planet." The android came to Xiao Ran and handed the space accessories to Xiao Ran.

　　"very good."

　　The cosmic berthing port stores a large number of ore resources that are ready to be transported to the capital planet or sold, and the warehouse of the army in the planet also has a lot of ore resources that have been mined, and the quantity is even more than in the cosmos berthing port.

　　"Drip!"

　　"After testing [-] trillion tons of various ore resources, the total value is [-] billion points."

　　"The [-] trillion tons of various ore resources are only more than [-] billion points, and the remaining blue gold source mines on the planet are actually only [-] million tons...!"

　　"No wonder."

　　Xiao Ran roughly took a look at the blue gold source mine and a few high-value ore resources, the value of other ore resources is very low, even dozens or hundreds of tons can be exchanged for one or two hundred 680 points, one hundred and thirty trillion. The exchange of tons for more than [-] billion points is all based on quantity.

　　If there are hundreds of millions of tons of blue gold source ore, the value is far more than tens of billions of tons of various ores. This is a huge price gap, so Xiao Ran is now ordering engineering robots to take the lead in mining all blue gold source ores. The remaining ores are selectively mined according to their value.

　　"Xiao Ran, look at this...!"

　　"Unexploited ore resource map."

　　Mu Fei opened the network of this planet's army and found some mineral veins that the army had not yet mined, or had no ability to mine.

　　After hundreds of years of uncontrolled mining, the entire planet has long since changed from a green planet to a desolate mining area. However, there are still a few forests in the place where there are more than ten mineral veins. Obviously, the mineral veins there are valuable. Expensive, or more advanced rare ore, even if it is mined at the technological level of the Silver Dragon Empire, it cannot be used.

　　"I didn't expect there was such a document. It just so happens that you, Mu Fei, bring thousands of working robots to investigate." Xiao Ran said to Mu Fei.

　　"Brother, I'll go too."

　　"Brother, we are going too."

　　It's boring to stay here and wait for engineering robots to mine ore, so several people want to go for a stroll.

　　"Okay, I will give you a thousand engineering robots by myself, which should be enough."

　　The three million engineering robots and the first exchanged robots have all been sent out to mine wildly. Now that a new mine has been discovered, Xiao Ran plans to buy another million engineering robots.

　　"Drip!"

　　Successfully purchased engineering robots, Mu Fei, Zhou Yi, Luo Xue...!Several people each flew to the target location with a thousand engineering robots.

　　Xiao Ran continued to stay in the spaceship where the ore vein was located to wait for news. Several engineering robots next to Xiao Ran were frantically mining ore. The ore value of this ore vein was neither high nor low-medium, and the reserves were amazing, so Xiao Ran planned to take all of it. mined.

　　...!

　　"How about it?"

　　"The master mine exploration robot has searched the entire planet, and found that there are twelve more mines that have not been found in the Silver Dragon Empire, but these mines are all located in the deep sea and volcanic areas...!"

　　"In the deep-sea volcanic area, the mineral resources in this place are generally not too bad. [-] engineering robots are sent to each place to mine at full speed. I would like to see what mineral veins are in those deep seas and volcanoes. Small surprise."

　　The engineering robots produced by the Imperial Army are absolutely suitable for mining work in any environment. The temperature of the volcano does not exceed [-], and the depth of the deep sea does not exceed [-]. It can easily carry out mining work, and these engineering robots come with a lot of equipment. , it is no problem to establish mining bases in the deep sea and volcanoes.

　　"Drip!"

　　"Big brother, we sent it again." Xiao Ran was excited when Zhou Yi connected to the communication screen.

　　"Have you found any rare mineral veins?"

　　"It is definitely a rare ore vein, one of the rare ores specially used to manufacture the core power acceleration system and defense system of the top starship."

　　"You tell me the name directly, I don't have much research on ores."

　　"Crystal titanium ore, a type of crystal titanium ore, there are not many reserves of ore like Neogene Earth, and the empire has banned mining, most of which are obtained from other planets."

　　"Crystal titanium ore was originally one of the main materials for the core power accelerators of the top starships of the Imperial H-GT Moro series before the first [-] generations, but because this ore is really rare and the reserves are small, the ultra-fast space jump acceleration The starship eventually stopped production, and it was replaced by the current blood ore used to make the material for the acceleration power system, and its overall performance is much worse than that of crystal titanium ore." Zhou Yi explained.

　　"I understand, but how do you know so much?"

　　"Haha! Because the family has collected a top-level starship of the H-GT Moro series. Now it is definitely a rare starship. The family won't let me take it out. Although the speed is not as fast as your starship, eldest brother. However, the ship can easily crush the speed of the top starships of the other academies."

　　"Ok."

　　"How much is the price of crystal titanium ore?"

　　"I'm afraid you will be shocked when you say it, big brother, [-] tons of crystal titanium ore is worth one billion points."

　　"what?"

　　Hearing this price, Xiao Ran was indeed taken aback. This is definitely the most valuable ore that Xiao Ran has ever been exposed to.

　　"What grade is that crystal titanium vein?"

　　"It's a pity that even the lowest-level ore veins can't be reached. I initially estimate that it can be mined about tens of millions of tons, but this is already very good. This kind of crystal titanium ore is in great demand by the imperial army. Ultra-rare ore, it is very good to find one on this planet."

　　"If the number is large enough, the imperial army will definitely use crystal titanium ore again to manufacture top-level starships, even king-class starships, but the output of tens of millions of tons is not enough for the imperial army's consumption in one day. I want to see crystal titanium again. I am afraid that it will take a long time for the top starship to be made of ore...!" Zhou Yi said with emotion.
