After returning to the mine, which had been renamed "Tang's Mine", the two of them first rested for a night, and the next day Sam went to the town to buy daily necessities, while Tang Feng couldn't wait to prepare to condense the silver in the mine.

Consciousness entered the star core space, and Tang Feng asked, "Star core, can you condense the silver in this area now?" Tang Feng asked, while drawing a range from the holographic analysis map, which was the area with the richest silver reserves in this mine.

This area is next to the abandoned gold mine, which was supposed to be a gold-silver mine or silver-gold mine associated with the gold mine, but unfortunately these gold-silver mines or silver-gold mines have not formed veins, so although the silver reserves here are very high and the grade is also very high, it seems that there is no mining value in the eyes of ordinary people, and it is too scattered!

The star core gave the answer very happily: "The silver in this area can completely condense a very small silver deposit, the reserve is about one ton, and it needs to consume 17% of the energy." However, the star core advises the host to spend a little more energy to condense the silver in this area directly into natural silver, so as to avoid the trouble caused by mining. In addition, according to the detection, about 100 kilograms of natural gold can be condensed in this area, which consumes 4% of the energy, and the copper content here is also relatively high, which can also condense a high-grade small ore vein, but it needs to consume 14% of the energy. However, if the host decides to condense the silver and gold in this area into natural silver and gold and condense the copper veins, then it will consume 53% of the energy stored in the star core. ”

As soon as he saw the information displayed by the star core, Tang Feng was also moved.

There is a saying in the industry, "Gold that is more valuable than pure gold is natural gold, and silver that is more valuable than pure silver is natural silver."

This natural gold is the natural formation of pure gold, of course, the purity is certainly not as high as the pure gold after artificial purification, this natural gold is actually commonly known as the dog's head gold, a natural gold nugget formed in vein gold or placer gold, which contains a little silver or copper.

Although the purity of this natural gold is far less than that of the pure gold that is often four nines, but in terms of value, natural gold is 5~7 times that of pure gold of the same weight, and the price of some natural gold is even ten times or even dozens of times that of pure gold of the same weight. At an auction in China, there was a piece of natural gold weighing about 1.7 kilograms that was auctioned at a sky-high price of 8.2 million yuan, because the natural gold naturally formed the appearance of Maitreya Buddha, although it is not as realistic as the artificially made pure gold Maitreya Buddha, but don't forget that this is a natural shape!

As a result, this piece of about 1.7 kilograms of natural gold was sold for 35 kilograms of pure gold! You can imagine how valuable this natural gold is!

Natural silver is the same as natural gold, but it is not as valuable as natural gold, but if natural silver is well shaped, it can still be sold for a sky-high price. In the State Geological Museum of Arizona, there is a piece of natural silver, which has a strange shape, but the size is no more than the size of an adult's palm, and the value is as high as 15,000 US dollars.

Therefore, in the precious metals mining industry, natural gold and natural silver are definitely the preferred mining targets! This thing is worth too much!

And the most important thing is that, as the star core just said, if it is condensed into a silver deposit, although it will consume much less energy, it will also have to mine silver ore, and then it will have to be refined, and finally pure silver can be refined and sold. Just the process of mining and refining in the middle is not something that Tang Feng can deal with now.

And if you spend a little more energy and condense natural silver and natural gold directly under the surface, then at least there is no need to mine and refine, as long as the thing is dug up, it can be sold directly for money, and the selling price is very high! Of course, if you can control the star core to condense natural silver and natural gold, and make the shape of these natural silver and natural gold more peculiar, maybe the price will be higher!

The comparison between the two, the high and low are naturally revealed! Or is it better to condense directly into natural gold and natural silver! Isn't it just 50% more energy consumption, now that our legs are better, we can find a uranium mine to absorb at any time, and we are afraid that we will not be able to replenish the energy? As for the high-grade copper vein, Tang Feng planned to condense it in an area 30 meters below the ground, not preparing to mine it himself, but after digging out the natural gold and natural silver, it was a condition for the land to be sold at a high price, after all, there are copper mines and no copper mines, and the price of this land is naturally different.

Since it has been decided to directly condense into natural silver and natural gold, then just do it! Tang Feng did not hesitate to give the order of condensation to the star core, and the star core immediately gave a deadline for the final condensation of natural gold and natural silver - one month!

When he saw that it would take another month to know the result, Tang Feng couldn't help but roll his eyes. It seems that although the function of this star core is magical, it is not an all-powerful God!

But then again, being able to directly condense the scattered silver and gold in the earth's crust into natural silver and natural gold is already beyond people's imagination, and it can't be too demanding on the star core, after all, the kind of thing that turns stones into gold can only be seen in those fantasy novels or immortal cultivation novels! It's still a normal world!

A month is just a month, isn't it just thirty days, we can afford to wait!

However, while Tang Feng gave the condensation order to the star core, he also asked the star core to condense according to the shape and size he requested. After all, a big, well-shaped natural gold or natural silver, the selling price will definitely be very, very high, once these natural gold and natural silver are really condensed according to Tang Feng's requirements, they can be regarded as a miracle if they are moved out of a piece.

For this kind of request of the host, the star core readily agreed, after all, as long as it is natural silver or natural gold, as for the shape and size, it is not a matter at all for the star core.

After giving the order of condensation, the rest of the matter is to wait, once the silver and gold under this ground are condensed by the star core into all kinds of strange and realistic natural silver and natural gold, then Tang Feng's happy life will really come!

After finishing the affairs of the star core space, Sam also drove back from Northman, of course, he also pulled a lot of fresh vegetables and meat, and for the next period of time, the two big men who had nothing to do except eat and sleep. Of course, if Sam had to go to the town bar for a drink or two at night, Tang Feng wouldn't be able to control the guy. Who made Sam such a prodigal in the United States?

Time passed day by day, and strange changes were taking place under the ground that no one knew, and Tang Feng finally threw away the crutch and stood up in Sam's amazement.

On this day, after the star core sent a reminder to Tang Feng that "condensation is complete", Tang Feng, who was full of apprehension, finally started his career as a big mine owner in his life!
