Mars will continue to accept various small planetary collisions in the following years, and it can be said that there may not be time to rest at all in the future, but fortunately, in the future, the asteroids that hit Mars will not be too large, and the maximum will not exceed the size of Ceres.

After all, the largest asteroid in the asteroid belt between Jupiter's orbit and Mars' orbit is only Ceres, and the other asteroids are not as big as Ceres.

However, Zhu Lei and everyone in the Ming Empire knew that the real test of Mars was five years later, when Europa and Mars collided, and that was when the test was the greatest.

In the following half a year, Zhu Lei and his fleet have been flying back and forth between the asteroid belt and Mars, in this more than half a year, Zhu Lei has moved the other three largest asteroids in the asteroid belt to Mars, these three small stars are all more than 400 kilometers in size, the names of these three asteroids are Homo sapiens, marriage and Vesta.

In addition, in half a year, the Ming Empire sent tens of thousands of small probes to the asteroid belt, which not only had detection functions, but also had positioning functions.

The main goal of these probes is to detect asteroids in the asteroid belt with a diameter of more than 500 meters, and once detected, these small stars will be located by the positioning device released by the probe.

Then wait for the civilian mining ships, or Zhu Lei's fleet, to pull all these little stars to Mars.

Of course, for those asteroids with relatively high mineral content, they will definitely not be pushed directly to Mars, but after the minerals are smelted, those slags will be transported to Mars by slag ships.

In the past six months, the private mining industry of the Ming Empire has also developed very rapidly, from the original total number of spaceships was less than 20,000 ships, and now the mining deposits of the entire Ming Empire have more than doubled, and the overall number has reached more than 50,000 ships.

Moreover, the number of medium and large mining ships has exceeded 1,000, of which there are no more than 50 large mining ships in the entire Ming Empire.

Although the number of medium and large mining ships is really very small compared to small mining ships, but unlike small mining ships, these medium and large mining ships can not only carry out long voyages and have the ability to mine anywhere in the entire solar system, but also these medium and large mining ships can carry a large number of small mining farms and mine at a very long distance from the earth.

For example, a medium-sized mining ship, he can carry eight small mining ships on it, and all the staff on the mining ship, and then fly with these spaceships and personnel to the outer Kuiper Belt of the solar system, or even farther away to mine, of course, first of all, the spacecraft must have enough living materials on it.

Since these medium-sized mining ships still use old nuclear power plant-type reactors, and the thrusters have only one plasma thruster, they are not very fast, and if they go to the Kuiper Belt for mining, then it will take at least two years to go back and forth, and even if it is a large mining ship, it will take more than a year to mine in the Kuiper Belt on the outer part of the solar system.

During this period, Daming Ming took over the mining group, and there were some sensational things that caused the whole Daming, including the five brothers mining ship, they brought back a huge platinum ore from the asteroid belt, and the platinum content of this platinum ore is as high as 50%, in addition to this ore has up to 30% iron content and less than 20% copper.

For the platinum ore mined by the Five Brothers, the entire Ming Empire was very sensational, even Zhu Lei himself was very surprised, although the Ming Empire has entered the interstellar era, and many precious metals are everywhere in the universe, but precious metals like platinum have been discovered so much in the human race just out of the earth.

Moreover, compared to gold, whether in the whole universe or on the earth, the amount of platinum ore is far less than gold, for example, platinum on the earth is 35 times more precious than gold.

And whether it is in the industrial field, in the medical field and other fields, the role of platinum is far higher than that of gold, so Zhu Lei was so surprised.

After calculation, the platinum content of this ore is as high as nearly 5 million tons, which is terrifying, but in fact, this number is nothing to the current Ming Empire, because every spaceship, especially medium and large spaceships, will use at least more than 100 tons of platinum on average, so when this ore arrives at the nearby Universe Mineral Trading Center, it is directly purchased by the Ming Empire official and Zhu Lei's Yongan Group.

And the price is also quite considerable, after all, so much platinum, except for the official of the Ming Empire and Zhu Lei's Yongan Group, other companies are not of much use, of course, it is also a little useful for jewelry companies, but this platinum mine is as high as five or six million tons, if it is smelted into jewelry, no jewelry company can eat it.

The official of this ore of the Ming Empire and Zhu Lei's Yongan Group finally came up with a price of 1.5 billion energy coins, after all, in addition to the platinum content of about 50%, this ore is also rich in copper and iron, you must know that the price of ordinary steel in the Ming Empire is also rising in a straight line, so it is very reasonable to give this price.

The price of this ore caused a sensation in the entire Ming Empire on the same day, you must know what the price of a small space mining ship is, at most it is only hundreds of thousands, but the first time the five brothers mined got such a big return, this is not a matter of ten times and a hundred times, but a whole of thousands of times, which of the entire Ming Empire is not red.

Although the four brothers who drove this small space mining ship spent more than half a year in order to drag this asteroid to the space mineral trading base near the moon, and the price of energy consumed was as high as several million, but the return of this asteroid alone is already crazy, you must know that the price of 1.5 billion can already buy the largest space mining ship of the Ming Empire.

Of course, the first batch of people to buy a space mining ship, except for the Five Brothers, the others are not bad, although the price of a single mineral for many teams is far less than that of the Five Brothers, after all, not any team has the luck of being able to find the platinum ore that was pulled back by their spaceship.

Moreover, although there are many precious metals such as platinum ore in the universe, it is very difficult to find them at once.

However, many teams have earned hundreds of millions of yuan in energy coins in just a few months.

Even among the first buyers, at least they earned hundreds of millions.
