In a few months, the pioneers grew very fast.


    After walking around trindadi Island, sun Cheng found that the changes here are indeed the same as they seem, and the changes are very huge.


    Many people on the island are now resident here. There is no hidden idea of the existence of the black market. Therefore, countries with a little strength on the earth now almost know the existence of such a magical island.


    At present, many human countries and forces have established liaison offices on the island.


    These liaison offices have as few as five or six people, and even as many as dozens or hundreds of people. It is said that the total number of permanent human beings on the island has exceeded more than 1000.


    The reason why those human countries and forces bother to set up a long-term Liaison Office on this island, which can not produce any materials and all necessities of life can only be purchased from the mainland, is because of the rules of the black market.


    The total number of materials used to trade with humans on the island is fixed. Although it will be refreshed regularly, the number is not large.


    Therefore, unless you buy the goods at the first time when they appear in the black market mall, you will have to wait until next month, or there is a force to grab the goods and break the contract.


    Because the lowest price of each set of equipment may need tens of millions of dollars, and the price of selling hundreds of millions of dollars at a higher price is very common.


    Trindadi does not accept the currency of human countries, but only accepts all kinds of rare metals and minerals for barter.


    Sun Cheng initially set this provision to leave sufficient preparation time for mankind, because whether they want to excavate minerals or buy from the international market, this process takes time.


    There are two reasons why the black market on trindadi was born.


    First, Sunson hopes to use the human forces on earth to help himself gather enough resources as soon as possible to speed up the development of Kwai Fu forces and the construction of explorer class ships.


    South America, where he chose the No. 2 base for development, is indeed a god given place. It is rich in minerals. Even if only selling mineral resources is enough to enable many countries in South America to maintain a good economy for a long time.


    However, no matter how rich a heaven given land is, it can''t have all the same mineral resources.


    At least in several South American countries controlled by the No. 2 base, sun Cheng''s Decepticons engineers have drawn detailed ore vein maps, including hundreds of minerals such as uranium and rare earth, which are either scarce or not at all.


    This is also the reason why after the gradual development and expansion of base 2, a large number of minerals have been imported from the Far East and Russia.


    The second reason for the establishment of the black market is sun Cheng''s efforts to avoid excessive attention from countries around the world.


    Since the fallen king suddenly ordered the Decepticons to invade the earth on a large scale six months ago, destroyed the main force of the second fleet of the United States, and openly invaded the communication systems of various countries on the earth, exposing the existence of Decepticons, human countries have invested a large amount of resources and manpower in exploring aliens for national security and various considerations.


    After that, the Decepticons fought with the US military in the Red Sea, the Autobots and Decepticons fought in Egypt, the Autobots and Decepticons fought with humans in Jordan, and even the laboratories of a series of arms giants in the United States were attacked.


    In a series of activities after Decepticons and Autobots were exposed, it is obvious that the role of human countries is to be invaded at will or even unable to resist.


    The United States, which has not seen tyranny on the earth for more than half a century, has been tossed and lost most of the main forces of the two aircraft carrier fleets.


    We should know that since World War II, aircraft carrier battle groups have always represented the military presence of the United States. Whether it is regional intervention or military coercion, old American aircraft carrier battle groups are almost everywhere.


    However, although the total number of aircraft carriers equipped by the United States has been maintained at about 10, due to the routine maintenance and technical upgrading of aircraft carriers, the maximum number of aircraft carriers that the United States can use for combat at the same time is generally about three.


    This is also the reason why the United States could finally swallow that tone after three aircraft carriers suffered heavy losses and the Autobots destroyed the laboratories of various domestic arms giants.


    Their most important conventional deterrence was paralyzed by the previous Decepticons. Naturally, no matter how arrogant the hawks were, they had to bow their heads.


    There are not many countries with aircraft carriers on earth, and the United States is undoubtedly the one with the most aircraft carriers and the strongest aircraft carrier combat capability.


    Even the United States is so badly bullied by aliens. It can be imagined the attitude of other countries in the face of these uninvited aliens.


    Sun Cheng is afraid of being stared at by too many eyes, so he took the initiative to get out of the black market of trindadi Island, so that all humans can personally end up in contact with their aliens.


    The commodities he took out to exchange materials with mankind were all advanced mechanical equipment and precision instruments in line with the current earth''s industrial level.


    Only a few countries on earth can produce such equipment. They are naturally a sharp weapon in the hands of politicians to suppress other countries, so countries that really need them can''t buy them even if they want to.


    What''s more, sun Cheng had to sell more to get more resources.


    He asked a Decepticon engineer who was specially responsible for producing all kinds of mechanical equipment sold on the black market to control the technical content of the equipment sold to be about five to ten years ahead of the current level of the earth, which is almost a generation of technology difference, which is attractive to most countries.


    Sun Cheng was very satisfied with the pioneer''s orderly management of the black market on the island.


    Accompanied by several of his men, he took a slight turn around the island.


    The forerunner has now learned and mastered sun Cheng''s original simple instructions.


    All humans stranded on the island need to calculate the accommodation cost according to the number of people and the number of days they stay.


    The island does not accept the currency of any human country, so those countries and forces that have established offices on the island can only pay with resources.


    The same is true for the food and fresh water they consume on the island.


    Sun Cheng is very satisfied with this learning ability. If the forerunner can exercise on the island, when he and the forerunner''s new body are all completed, he doesn''t mind making the forerunner the first commander under his command, and begins to shoulder more command and combat tasks.


    The premise is that there is no hip pulling problem.


    Several tall mechanical soldiers strolled around the island, which naturally attracted a lot of attention.


    As a result, when sun Cheng and his men came to the island, near the huge temple building that had been simply and roughly named "black market", several humans in suits appeared and stopped sun Cheng and his men.


    "Are you confused, sir? Can you give us a few minutes? We want to talk about a cooperation with you?"


    Sun Cheng looked at the humans who called him in surprise, and his eyes flashed red.


    Among these people, he recognized a familiar face!
