Outside the embassies of each civilization is the interstellar trade port of the Protoss civilization, and the interstellar trade port of the entire Protoss civilization is divided into three parts.

The first part is located in the outermost area of the entire interstellar trade port, in this area, the people who come to trade are the fourth-level civilizations near some foreign Protoss civilizations, although most of these fourth-level civilizations are located not far from the Protoss civilization, but these world civilizations are not subordinate civilizations of the Protoss civilization, so these civilizations have no subordinate relationship with the Protoss civilization.

But although this is the case, but because these civilizations are some low-level civilizations near the Protoss civilization, they can also be protected by the Protoss civilization, and it is also conditional to get the protection of the Protoss civilization, that is, these civilizations will provide a large number of cheap resources to the Protoss civilization every year.

Well, the outermost area in the trade port is where these civilizations and the Protoss civilization trade resources, but in fact, because these civilizations belong to the lowest cosmic civilization in the universe, there is nothing to get hold of except for the lowest-end primitive resources and some specific native products trade.

Of course, the technology of the same fourth-level civilization can still be bought in this trade area, but these fourth-level civilizations traded in this area have to pay huge taxes to the Protoss civilization every year, after all, compared to the certainty and danger of those black markets, at least the trading market established by the Protoss civilization is a regular trading market, which is recognized by most of the fifth-level or above civilizations in the universe, so even if it is traded here, it has to pay a huge amount of wealth to the Protoss civilization, These civilizations also prefer to trade here.

After all, trading in the black market or trading privately is too dangerous, and if you are not careful, you may lose both people and money, and the transaction here is at least guaranteed by the Protoss civilization, and the Protoss civilization, as a fifth-level civilization, their credit can still be guaranteed.

Therefore, there is no act of killing people and selling goods here, even if it is out of the area where the Protoss civilization is located, the Protoss civilization is a fifth-level civilization, and the deterrent effect of the Protoss civilization is still very strong, and no civilization dares to carry out the act of killing people and selling goods.

The second area in the trade port is the rich civilization trading area of the high-level civilizations in the galaxy, after all, all the fifth-level or above civilizations in the galaxy, each civilization has its own large number of subsidiary civilizations, and the fourth-level civilizations in the first region are different, although most of these subsidiary civilizations are also fourth-level civilizations, but the Protoss civilization treats these civilizations with obvious differences from the world civilizations in the first region.

In any case, most of these civilizations are also fourth-level civilizations, but behind these civilizations are the powerful fifth-level or above civilizations in the galaxy, as the so-called dog beating to see the master, this rule is obviously very applicable in the galaxy, not to mention that although these civilizations are subsidiary civilizations of fifth-level civilizations, the technology possessed by these civilizations is certainly not comparable to those fourth-level civilizations in the first region.

Although most of these civilizations are fourth-level civilizations, there are also very few quasi-fifth-level civilizations, and even some fifth-level civilizations can still see some technologies that only fifth-level civilizations have in this trading market, but the price of these technologies is very expensive, and there are a large number of fifth-level civilization products for sale in this area, and it is obvious that these products are the products that can only be produced by the fifth-level civilization behind these civilizations, and these civilizations are just agents of the civilization.

There is no need to pay a huge amount of wealth to the Protoss civilization like the first area to trade in the falling area, after all, there is a high-level civilization standing behind the civilization in this area, and many of the products traded here are industrial products that can only be produced by the fifth-level civilization, even if the Protoss civilization sometimes buys some industrial products in this area, so naturally the taxes to be paid here are also much lower, and after trading in this area, entering and exiting the Protoss civilization will not be restricted by customs.

The last area is the advanced trading area of the Protoss civilization, all the sides of the transaction in this trading area are the existence of civilizations above level 5, and the civilizations above level 5 belong to the existence of the overlord level in every region of the galaxy, these civilizations not only have a long history, profound heritage, and strong military strength, so the civilization level of each of their civilizations is not much worse than that of the Protoss civilization, and some are even higher than the civilization level of the Protoss civilization.

Therefore, the civilization that trades here does not have to pay high taxes at all, as long as it pays a small amount of taxes, and even many goods do not need to be taxed at all.

In fact, the rules of the interstellar trading port of the Protoss civilization are very strict, and all the civilizations in the low-level trading area in the interstellar trading port are not allowed to enter the high-level trading area, while the high-level trading area can enter the low-level trading area.

After all, the various technological products in the high-level trading area, if there are no special circumstances, are basically blockaded by the low-level civilization in the universe, even if there are people from low-level civilizations who inadvertently break in, they are not allowed, and those with minor circumstances will be expelled immediately once they are discovered, and if the circumstances are serious, then the Protoss civilization will also hold its civilization responsible, and even use force to maintain the laws in the Protoss civilization trading port.

In fact, this set of laws is very common in the galaxy, and basically all advanced civilizations will do this, but in different forms.

……

Just as Zhu Lei and the others were resting while learning about the civilization of the Protoss from all aspects, after nearly two months of rest, the delegation sent by the high-level of the Protoss finally arrived at this living planet located on the edge of the Protoss territory.

The high-level representatives sent by the Protoss civilization this time are of very high standard, after all, the visiting team of the Ming Empire also has the existence of the Qingwang this time, so the high-level representatives sent by the Protoss civilization must also have at least people with the same identity, and this time the high-level representative of the Protoss civilization has the highest identity is the second prince of the Protoss civilization, and is also the second heir to the throne of the Protoss civilization. He also sent a person equivalent to the level of the prime minister of the ancient Ming Empire to preside over the friendly talks between the Ming Empire and the Protoss civilization.

After all, although the second prince was the most noble person in the delegation of the Protoss civilization, he was not good at the specific exchanges and negotiations of civilization, so these aspects were handed over to others.

Therefore, it can also be seen from here that the high-level of the Protoss civilization attaches great importance to the arrival of the visiting mission of the Ming Empire, and even did not hesitate to send a person at the level of a prime minister to preside over this meeting.
