Of course, they don't know these four brothers, after all, they are just civilian forces, in the final analysis, they are just the middle class of the Ming Empire, and they will definitely not know about these top secrets of the Ming Empire.

However, although they don't know this, this does not prevent them from knowing S-level metal minerals, after all, if they can be used by the Ming Empire as S-level metal minerals, then this kind of mineral deposit must be very rare, even in the entire galaxy, it is also very rare.

What's more, according to the information released by the central computer of the Ming Empire, this black gold metal is also one of the most important metals for the civilization of the Ming Empire to advance to the sixth level or higher civilization, this metal is one of the most important materials used to make various space weapons, of course, the Ming Empire is still only a fifth-level civilization, and the research involving space is not very deep, and the four brothers of the Zhang family do not know from what channel the Ming Empire obtained This metal material is one of the most important materials for manufacturing space equipment. But this is not something that they, the middle class of the Ming Empire, can understand.

"What, S-grade mineral metal, how is this possible, according to the data of the Central Intelligent Computer of the Ming Empire, the S-level mine is a very rare mineral, and many S-grade metal minerals are not many in the entire galaxy, and some of the stools do not exist even in the galaxy.

But there are S-level metal minerals here, brother, you didn't lie to me! ”

Hearing Zhang Laoer's shout, Zhang Laosan's mood that had just calmed down became excited again, you must know that this is an S-level metal mineral, if other civilizations know that they have found these S-level metal minerals, then there will definitely be a lot of civilizations to come and grab it, even if the entire civilization is destroyed, especially the civilization of level five or above has a certain understanding of the use of these S-class metals.

"Yes, the third one, it is really an S-grade metal mineral, and it is also a very rare space attribute metal mineral, so no matter what, we must mine these S-grade metal minerals, compared to other minerals, these black gold metal minerals are too important, even if all the minerals in this star field are added up, it is impossible to exceed these black gold metal minerals."

"Okay second brother, I'll go and mine it myself."

"No, third child, you continue to look at the data here, I will immediately report this information to the base camp of the Ming Empire, after all, this matter is too important, I need to activate the most advanced communication equipment in the world to report this matter, after all, I don't know when we need to mine minerals by hand, and black gold minerals are so important, I am not afraid of ten thousand, just in case."

And you go and order the fourth, equip all the weapons in our fleet, all the personnel on the spaceship are on first-level alert, release all the automatic weapons on the spaceship, and activate all the radar equipment on the spaceship to conduct first-level alert within the surrounding range of five light-years.

After all, these black gold minerals are too scarce, and they are so useful to the Ming Empire, we have to be on guard against whether people from other civilizations have discovered these metals, so we must be fully prepared.

There is also the fact that we have just killed these cosmic creatures, since there is black gold in this star field, then the bodies of these cosmic creatures must contain re-metals, so the corpses of these cosmic creatures are all collected from it, after all, every gram of black metal like this is very precious, like this S-grade black crystal metal, the value of one gram of weight is equivalent to a cosmic battlecruiser of the Ming Empire, and the volume of cosmic creatures like this is so huge, if they really contain black gold metal in their bodies, Then there must be a lot of each cosmic creature in the body, so we can't let go of the corpse of a cosmic creature. ”

"Second brother, since these metals are so precious, why do you have to notify the Ming Empire to mine them, you must know that if we mine them, the price will be even higher when they are transported to the Empire, and if the Ming Empire officials come to mine them, then the value will be reduced a lot."

"No, you're wrong, if the ordinary metal is indeed as you said, we will mine it ourselves and then transport it to the Ming Empire to sell it, so the value is indeed much higher, even if you hire a mining company to mine it, the value is much more cost-effective than the official direct mining of the Ming Empire.

But these black gold metals are different, because black gold metal is an S-level strategic resource, not to mention that this resource is a necessary mineral element for the civilization of the Ming Empire to move towards a higher level, which is very important for the entire Ming Empire, not to mention that like this S-level strategic resource, there is a special explanation in the central wisdom of the Ming Empire, any kind of S-level strategic resource, the price of transporting it back is exactly the same as the official mining team sent by the Ming Empire to mine, after all, compared to the S-level strategic resources, Such a small loss of the Ming Empire's energy coins can be slightly ignored.

But just in case, we will mine first, and we can mine as much as we can, after all, it will take a year or two for the official fleet of the Ming Empire to arrive here, and in such a long time, we can't guarantee that no other civilization will come, so we must mine as much as we want, and the mining is our own, even if there are other civilization fleets coming, we don't have to worry about all the minerals falling into the hands of others. ”

"Okay, second brother, I'll report it, and leave the matter of mining minerals and collecting the corpses of cosmic creatures to the fourth and fifth children!"

After finishing speaking, Zhang Lao Er hurriedly walked out, after all, this matter is too important, it is a matter of the Ming Empire and the entire human civilization, so he can't afford to be the slightest sloppy.

And Zhang Laosan continued to monitor the data on the display screen, after all, at this time they have not determined the specific number of S-grade black gold metal minerals, not to mention that he also expects more S-grade metal minerals to be discovered, but in the subsequent data, in addition to S-grade black gold metal minerals, no other S-grade or S-level minerals have been found, but A-grade metal minerals and minerals below A-grade have been found several.

But at this time, they can no longer afford these A-grade mines or other rare minerals of A-grade or below, which they were very happy with before.

Minerals of Grade A or below, although precious, are actually very significant in the entire Milky Way, but they are not the same as the black gold metal they have just discovered.

So when he saw that some A-grade mineral resources had been discovered one after another, although they were still very happy in their hearts, they were still slightly disappointed.

But this is also normal, there are so few minerals of S grade or above in the universe, there is a ferrous metal here is already their luck, if two or more are found, it is called abnormal.
