Zeng Rong thought that there was money to be made now. 100 khakis, and 1 million khakis, those are two completely different concepts!

It's just that a simple transformation of Black Treasure can increase the value by 10,000 times, and the speed at which Black Treasure makes money is simply comparable to the money printing machine on the earth!

However, Zeng Rong still felt a little strange, a ton of iron is only 100 khaki, why is it so cheap? This is no longer the price of cabbage. You must know that Zeng Rong is in the hotel, and he will have to pay 1,000 khaki coins for a day.

In his consciousness, Zeng Rong found the answer in an instant.

It turns out that when cosmic technology has developed to a certain extent, interstellar transportation is as convenient as transportation between two cities in the Earth era.

Unlike the process of iron ore mining on Earth, when interstellar transportation became very simple and convenient. A large number of interstellar mining ships can sail directly to unmanned stars, mining stars.

Finding the veins is as easy as digging for iron.

On the earth, because of the limitations of science and technology, only the veins on the earth can be taken, but in the interstellar era, an administrative star can mine the veins of uninhabited planets around thousands, tens of thousands of star systems, plus the mining is completely automated by robots, as long as there is money to get a set of interstellar mining equipment, the first-class metal is like flowing water is continuously extracted, so that the cost of the first-class metal is basically the cost of transportation.

However, secondary metals are different, the secondary metal veins that exist in nature are very rare, and the performance of secondary metals is indeed higher than that of primary metals. It's also a huge leap forward to be able to create something even more powerful. The reason for the high price is that simple.

And want to refine secondary metals from primary metals. The technology and equipment requirements are very high, and the materials consumed are too much, and it is not even cheaper to buy them directly in the natural state.

These two reasons are the reasons for the high price of secondary metals.

"Do you recycle metal here?" Zeng Rong asked directly.

"We don't buy back primary metals, we only buy back secondary metals, or secondary metals or above." The staff said, "It's just that if we buy it back." The price is ten percent lower than the market price. ”。

"It's okay." Zeng Rong smiled, it's only ten percent, although it can make this metal material trading company earn a lot of price difference. But it also saved Zeng Rong from looking for buyers everywhere.

On the second floor, Zeng Rong read it all, but it was strange to find that gold was actually a second-class metal. I thought about it for a moment. Gold is also quite special. This inert metal, even if it has been buried in the ground for thousands of years, is dug up as if it had just been produced. This strong anti-oxidation and corrosion-resistant properties have been applied in some special fields.

Of course, this is not to say that the price of secondary metals is the same as the price of gold. It is obviously much cheaper than Star Iron, although it is also a secondary metal.

The second floor is finished. went to the third floor and saw the eyes full of tertiary metals, Zeng Rongyou was stunned for a moment, it turned out that uranium, radium, and plutonium on the earth are all tertiary metals!

However, in the metal exhibition hall of this planet, Zeng Rong can see dozens of radioactive metals! According to the classification of the Tianxuan universe, these radioactive metals are just the lowest level of energy metals, not only can they not provide sufficient energy, but indeed, compared to the energy required for space jumping, even the nuclear reactors on the earth are a little weaker. And it also carries a negative ray that endangers the genes of life. This negative ray is the nuclear radiation on the earth!

Sure enough, in the exhibition hall of the fourth-grade metal, Zeng Rong saw the special uranium and other metals produced by Heibao, where they were classified into primary energy blocks. It provides a lot of energy and has no side effects.

After looking at the fourth floor, before Zeng Rong asked to go to the fifth floor, the staff said apologetically, "I'm sorry, metals above level 5 are all forbidden, and we ordinary people are not qualified to have them." ”。

"It's okay," Zeng Rong said with a smile, it was enough to be able to see metals of level one to four, and let Heibao remember the taste of these metals.

The veins of secondary metals are very rare, and the veins of fifth-grade metals are encountered? Zeng Rong didn't think he would be so lucky. After taking a look at the information, Zeng Rong immediately learned that the fifth-level metal veins could only be discovered in the unusually large planets, or in the star cores of some planets.

Those unusually large planets with obvious signs have long been occupied and mined by various forces. The only way to find a new giant planet is to explore in remote and dangerous unexplored star fields.

And if you want to enter the core of the planet, it is even more difficult, and it is very difficult to cross that thick, high-temperature and high-pressure magma layer.

Zeng Rong didn't think about finding any planets with high-level ore veins, as long as there was a planet with first-level ore veins. While cultivating together with Black Treasure, you can also use the particularity of Black Treasure to make a lot of money!

After the idea was taken, Zeng Rong left the metal trading company, and the next thing was to buy a spaceship.

The city functions of the khaki star are very clear, the spaceship trading center, in another city, Zeng Rong flew for nearly two hours, flying more than 2,000 kilometers, before arriving at the place dedicated to trading spaceships.

Alexandria, the largest spaceship trading center near Khaki City.

When he arrived in Lishan City, along the way, Zeng Rong really opened his eyes!

All kinds of spaceships, coming and going in the sky, the scene inside is close to the scene in the science fiction film that Zeng Rong saw on Earth before

There is also a spaceship, the pilot should be an expert in the control of the spaceship, and he actually played the spaceship jump in mid-air, every time the engine of the spaceship starts to jump, it can fly out of a few hundred meters, and the hull does not have a trace of bumps, when staying in the air, it is very stable.

"The G278 spaceship, an antique from three million years ago." This spaceship also seemed to have attracted the attention of Yanhua No. 1, and after independently probing, he continued: "On the ship, there are two awakened humans with two drops of cosmic force condensed in their bodies. However, the hull seems to have undergone special modifications, otherwise there is no way to keep the spaceship three million years ago so intact, it must be added with special materials, which retains stability and increases power, and is worth three million khaki coins. ”。

Soon, Zeng Rong was shocked by the scene in front of him, within two hundred miles, like a huge stadium, the ground with red and yellow lines intersecting to mark the location of the spaceship, thousands of spaceships of different shapes, parked within the planned docking line, of course, between each spaceship and spaceship, there is a silver villain.

"Master, look at those little silver people." Yanhua No. 1's voice appeared again: "These villains, called maintenance silvermen, are the monitoring guards given by the businessmen who sell spaceships, and they are directly connected to the computer on the spaceship, and can monitor whether their spacecraft is damaged or stolen, and with the existence of these maintenance silvermen, as long as the spaceship is damaged, the silvermen will automatically find the resources that can be used on the spaceship, and after the owner's consent, the spacecraft will be repaired, which is very convenient!" ”。

Zeng Rong originally thought that the spaceship in the universe was similar to the car on the earth, and if there was damage, he could find a repair shop, but he didn't expect that the space technology had reached such a level that there was no need to manually detect whether there was damage, as long as it was fused with the idea of the maintenance silver, it could be repaired independently.

Sou!

At this time, Zeng Rong's side appeared a human being wearing a suit, but his skin was green, but looking at his face, it looked like a strange shape in the movie, with a slightly longer neck and a huge head on his head.

If it weren't for Yan Hua No. 1 telling him that this person was a human in time, Zeng Rong would probably not hesitate to make a move, after all, such a human would look too shocking.

"Hello sir, my name is Batak, I'm the administrator here, how can I help you?" The human who just arrived and looked like an alien, bent his legs slightly, his upper body hung down, raised his head and looked at Zeng Rong with only one eye, and asked.

"Ahem, hello, Batak." Zeng Rong coughed a little embarrassed, then took out a cosmic coin from his pocket and handed it to Batak.

"Woo...... Cosmic Coins! Batak looked at the cosmic coin in his hand, and couldn't hide his excited expression, and even his body began to tremble with joy!

You know, like Bakhta, as an administrator here, on the premise of counting tips, a year, but only a salary of more than 100,000 khaki coins, but as soon as Zeng Rong shook his hand, he gave Batak a month's salary, and he was really wealthy.

"Sir, if you have any orders, please say, as long as I can do it, Batak will definitely try to help you, if you want to ask for bodyguards, you see me done!" At this time, Batak regarded Zeng Rong as a rich young master, and began to stutter without sparing.

Through the introduction of Yanhua No. 1, Zeng Rong learned that this strange human of Batak actually had a drop of cosmic force in his body.

Such a body is considered a master among ordinary people, but for the sake of a wrong judgment, he is so out of shape! It seems that the development of this scientific and technological civilization has nothing to do with the fairness of the social system and the distribution of resources!

"Batak, I'm so sorry, I don't need bodyguards for the time being, I'm here to pick a suitable spaceship." Zeng Rong spread his hands and said. (To be continued.) )

PS: ps: Thank you brother for the annoying classmate again.
