During the dust storm on Mars, the interplanetary trade team led by Wang Xian still negotiated with Zero Point Harbor, and the exploration department took the initiative to observe the dust storm and take care of their spacecraft.

It has to be said that in the face of the dust storm that can only be called a global disaster on Mars, the two Hengyue-class spacecraft withstood the test and did not suffer any damage, and then with the assistance of the immigrants from Zero Point Harbor, they found the low point and blocked the impact of the dust storm through the tall mountain, so there was no loss except for a lot of red sand and gravel on the spacecraft.

"However, the effects of dust storms are still there, especially when we take off, we have to be exposed to the Martian atmosphere, even if we use fusion energy reactors, we have to choose the right weather to ensure maximum safety."

After receiving the conclusion sent by the exploration department, Wang Xian pouted slightly, had no opinion, and concentrated on studying how to talk about the business of Zero Point Port.

"What we provide is the most scarce materials in Zero Point Port, so we don't have to worry about not being able to sell, the key is the price, how much to sell, and what we can bring back."

Since the joint fleet is running a long trade route, it no longer focuses on the supply and demand of commodities and the price difference between the two planets, but has to focus on multiple planets, which makes the complexity of the problem increase exponentially.

Moreover, even in the history of mankind, such a multi-planetary trade route exploration is the first time, and if it can be successfully maintained, it will be no less significant than the ancient Silk Road, the Strait of Malacca, and the Suez Canal on the oil route.

"Therefore, even if the profit is not as high as imagined, it is good to achieve such a goal, which can be regarded as proving that interplanetary trade is indeed profitable, so that the sub-investigation has a result, which means that the East Galaxy Company is worth considering continuing to invest in the future." Wang Xian muttered to himself.

He flipped through the list of foreign trade commodities provided by Zero Point Port, and several commodities on it were out of stock, obviously because the factory had not yet been completed, and it had not been put into production, and it was taken out first to fool people.

"The first item, Martian grain... The price is 50,000 yuan/ton, which is 20 times the price quoted by the earth, but considering the cost of transporting it, there is a lot of profit! ”

If Cao Chuan would notice here, the lighthouse country actually found a way to make a fortune on ordinary Mars - grain. Mars has carbon dioxide, nutrient-rich volcanic sediments, and then uses fusion power plants to provide electricity and heating, and grows crops that like to grow in a backlit environment, and you can produce food.

The advantage of Martian grain is that the gravity of Mars is low, the freight to ship it out is cheap, and its location is closer to the asteroid belt than the Earth, which generates profit margins.

However, if this continues, the lighthouse country has a superior food planting environment in the country, and even the zero point port they occupy is vigorously developing agriculture, is it possible that the lighthouse country will really become an agricultural power in the future?

Wang Xian didn't care about this kind of thing, and he wouldn't be as boring as Cao Chuan, he found that Zero Point Port did have a chance to trade, and planned to purchase 1,000 tons of grain and sell it to Ceres 024 Port in the asteroid belt.

"But wait..."Wang Xian suddenly hesitated, remembering the Taoyuan Port on the other side of the planet, he flipped through the information provided by the other party for comparison, and a hint of amusement flashed on his face.

"I didn't expect Taoyuan Port to also provide grain trading, do you want to toss it again?" Wang Xian had previously asked the employees of the trade department to spread rumors that Taoyuan Port was also interested in their goods.

Now, Taoyuan Port is really involved, and he has to think about it more.

A few minutes passed, it seemed that Zero Point Port was quite sincere, and the price had reached his psychological expectations, Wang Xian considered tossing it again, and Zero Point Port really wanted to give up the idea of talking, and planned to give up, first according to the previous idea.

He flipped through the rest of the list, except for food, there were not many commodities that interested him, and because the establishment of Zero Point Port was too short, there were relatively few commodities developed, such as some technological products, which did not have much advantage over the production of the East Galaxy Company, whether it was transported to the asteroid belt or transported back to the moon, the profit margin was not large.

In order to prevent missing opportunities, he still has the patience of professional habits to record the supply and demand of goods, profits, and the main transportation costs, and through computer processing, comprehensive analysis, to obtain a more intuitive table, telling himself what commodities are worth trading and what commodities are not worth trading.

With a clearer plan in mind, you can negotiate with Mayor Princeton.

Because of his neighbors on Mars, the mayor of Princeton always had a feeling that he was being manipulated, but the local side of the lighthouse country asked them to allow them to do loss-making business to accelerate their own development, so he had to work hard to continue the conversation.

In order to prepare 1,000 tons of grain for trading, they even cut part of the food ration, and in exchange for 50 million, compared with the billions they paid, it is really a drop in the bucket.

He gritted his teeth, hoping that trade would allow them to develop faster during this time, and when the large spaceships on the local side were built, they would not be as embarrassed as they are now, and they would have to be controlled by others everywhere.

The trade was reached, and the East Galaxy Company sold 70% of the goods in the spacecraft to Zero Point Port, including the exploration department, relying on the extra cabin to transport a small batch of goods, taking the opportunity to make a lot of extra money, as the department's performance.

In the process, although the name of Taoyuan Port was mentioned repeatedly, even the mayor of Princeton finally realized that it might be just a façade created by the East Galaxy Company, and they actually had no contact with Taoyuan Port at all.

Originally, the joint fleet had a plan to visit Taoyuan Port, but because of the dust storm, it would be very expensive for them to go by spaceship, and the distance between the two places was more than 7,000 kilometers, and it was even more difficult when the land route was completely blocked.

After the discussion of the fleet, reported to the East Galaxy Company, they decided to temporarily give up visiting Taoyuan Port, they are mainly to accumulate experience, study the possibility of planetary trade, if they find a profitable trade route, there is an opportunity to see if there are other business opportunities along the trade route in the next few years, there is no need to rush.

More than ten days later, the Martian dust storm became smaller, and the distant starlight could be seen again, so the long-delayed fleet no longer wasted time, and resolutely set sail, bringing 1,000 tons of loaded grain, 1,000 tons of messy Martian "specialties" that could not see actual benefits for the time being, and the target was the asteroid belt.
