Trindaddy Island does not prohibit any national forces that find it to land on the island, and is willing to trade with any force, although it has caused the unhappiness of some human countries, such as some old powers in Europe and the United States, but who cares.

It's just that the forerunners learned Sun Cheng very well, and he didn't offend those human countries to death.

It is true that Trindaddy Island does not exclude trading with any human country, but any human power that wants to buy high-quality products from the black market needs to ship the rare metals and rare earths paid for to the island within the specified time after placing an order, and the ordered goods also need to be shipped back by themselves.

This provides the feasibility for certain powerful rogue states to join forces to monopolize goods on the black market.

The forerunners will not interfere in this process, so whether the materials will be intercepted by the navies of some countries when they are transported, how to transport the ordered machines back, whether the road is unsafe, etc., is not something they need to consider.

The hundreds of machines and instruments sold on the island are specially selected by Sun Cheng in the military, heavy industry, and high-tech fields, and they are about one to two generations ahead of the current level of earth science and technology.

Therefore, every national power that landed on the island with a purpose was happy to place an order when they learned that there was a group of aliens who were willing to trade with them, and even established a trading market on this island to provide some more advanced machinery and equipment than the current earth.

In the more than one month that Sun Cheng has been designing and perfecting the small spacecraft, the forerunner has successfully sold seven batches of products.

Seven of the eight material storage warehouses built in a corner of the island have now been filled with rare metals, rare earths and other materials that were used to pay for by the forces of the human nation when they were traded before.

If Sun Cheng does not go out of the customs again, without more authorized pioneers, he can only continue to build more material storage warehouses on the island.

After digesting the information shared by the forerunners, Sun Cheng did have some more recognition for him.

The changes on the island during this period of time only surprised him slightly, but it was still roughly within his expectations.

With the terrifying operation ability of sappers and thousands of robots of various types, a small island with a total area of only ten square kilometers has been tossed by the forerunners for a month, and if the island is still the same as before Sun Cheng gave up studying the spaceship, he will doubt the ability of his group of subordinates.

"At present, the main force of buying a large amount of equipment on the island is Britain and France, which almost cover the first batch of about ninety percent of the machines and equipment temporarily released on the black market...... The United States is followed by Japan and Russia...... Although the United States also landed on the island to contact us at the first time, because the first meeting was unhappy, they almost did not grab the first batch of products since the opening of the black market, and they could only wait for the second batch of goods to be put on the shelves......"

Since it is a black market, of course Sun Cheng will not open it to sell things.

Unlimited shipments not only fail to sell at a high price, but also satisfy the needs of coveted human countries in a very short time.

The consequences of this can only be two, either they will lose the desire to continue buying, or they will become more insatiable in their desire for more technical products.

From the beginning, Sun Cheng never thought of selling goods with too high technology content.

In the future, even if the goods on the black market will be updated, they will not be much more advanced than they are now.

He doesn't have to worry about not being able to sell things, anyway, there are so many human countries he wants to buy.

The black market is only slightly more expensive, and only accepts rare metals and rare earths for barter, without any strings attached.

For this alone, there is no need to worry about no buyers.

Under the guidance of the forerunners, Sun Cheng came to the eight warehouses that had been filled.

These are several warehouses manufactured according to Decepticon standards, with a length, width, and height of 100, width, and 20 meters.

Directly in front of the warehouse is an automatic roller shutter with a height and width of 10 meters.

As the door of the warehouse opened, what Sun Cheng and the others saw was not a messy pile of metals and rare earths, but a neatly stacked container.

A chip is implanted on the top of the container.

Sun Cheng swept his gaze, and the weight, quality, type, etc. of the rare metals filled in the box all came to his mind.

"Well done!"

He was very pleased with the arrangement of the Precursors.

For a long time, Sun Cheng implemented various standardized containers inside the No. 2 base.

It's not that he thinks that standardized containers can bring convenience to bulk cargo handling, in fact, containers can indeed bring some convenience, but it is indeed convenient for him.

Because Sun Cheng often uses the spherical space to transport and store some materials and even robots, the spherical space in his body, although because Sun Cheng has been steadily providing sufficient energy liquid, the total capacity of the space is constantly expanding.

But no matter how much the spherical space expands, there is still a limit.

Scattered items will take up a lot of space.

In contrast, a standardized container only needs to be filled with things, which can save a lot of space.

And when it is needed, Sun Cheng can take out the neatly classified containers at any time, which is very worry-free.

It just so happened that some time ago, he had just cleared out most of the things in the spherical space and temporarily placed them in his own private warehouse at Base 2.

Looking at the various rare metals and rare earths piled up in several warehouses on Trindadi Island, Sun Cheng didn't say much, and took a moment to put them all into the spherical space, looking at the spherical space that was refilled with a lot of things, his heart was full of joy.

This special existence hidden in his body, which is suspected to be an imaginary space, has been slowly expanding by absorbing energy since he mastered it.

In the past year or so, Sun Cheng has packed a large amount of high-purity energy liquid into a ball-shaped space for absorption and continued to expand.

After absorbing nearly 20% of the energy liquid accumulated in the second base for more than a year, the interior of the current spherical space has expanded to a hemispherical space with a radius of more than 270 meters.

This gradually huge private space can be said to be Sun Cheng's biggest secret after being able to freely shuttle between the two worlds.

Even as the interior of the spherical space continued to expand, it began to help him more and more.

For example, Sun Cheng's private legion combat system designed for himself, which allows him to store a large number of troops in spherical space, is one of the cores.

For example, a month ago, the reason why he suddenly thought that he could design a small spacecraft to land on Mars without waiting for the explorer-class spacecraft to be manufactured, was that he suddenly thought that he could use the spherical space to transport a large number of robots to Mars together.

This will not only save a lot of time, once the construction of the Mars base begins, and with a whole planet to provide various materials and energy for itself, Sun Cheng's power development will be ten times or even a hundred times that of now.

"Over there at Base No. 2, it will take about half a month to build the spaceship! Until then, it's time for me to prepare! ”

Sun Cheng thought so in his heart, and suddenly the forerunner beside him turned pale, and turned to report to Sun Chengyu: "Master, the Autobot Drift is here!" ”
