There was no way, and in the end, Ishida Taro still had to buy 10 million tons of steel from Qin Yi's side at a price of 3,800 Chinese dollars a ton.

Although this price is only 200 Chinese dollars a ton cheaper than that transported from the ground to space, the tens of millions of tons of steel are also 2 billion Chinese dollars cheaper, which is not a small number, and Chinese dollars are very valuable.

What's more, it's not just a matter of saving a sum of money, because it's in space, it also saves the trouble of transportation, saving his strength and time, which is why Qin Yi was able to pinch them, because this is the best choice, although the price is really not cheap.

After talking about business, Ishida and his party left quickly, but not long after Ishida's front foot walked, Uncle Sam from North America sent someone over, and the purpose was the same as Ishida and the others, they all came to buy steel.

The Japanese have a 'Kaguya Project' in space, and are ready to rely on their own scientific and technological strength to build a large spaceship comparable to the Blue Dragon; Uncle Sam in North America has once again proposed a huge 'Apollo Plan', and the new Apollo Program is different from the original moon landing program, and the purpose is also to build a large spaceship that can go to the asteroid belt to mine asteroids.

In addition, the European Space Agency has also proposed a "Columbus Project" to build a large spacecraft called "Columbus" to recreate their glorious history hundreds of years ago.

The polar bears came up with a 'Krolev' plan to build large spaceships to mine asteroids in preparation for the construction of space warships in the future.

Even the Indian elephant has an ambitious 'Light of India' project to spill curry flavor throughout the solar system.

Ambitious countries have put forward their own plans, and everyone clearly sees the importance of mining asteroids, especially with the lessons of lunar mining in the past, and everyone is not far behind.

Now all the territory and resources of the moon have been divided, the Chinese people account for the absolute majority, and the other countries together are not as many as the Chinese people, and some slow countries have been constantly protesting every time the United Nations General Assembly is held, shouting that the moon is the moon of the entire earthlings, demanding the sharing of lunar resources and so on.

Everyone remembers this lesson firmly, so in the matter of mining asteroids, everyone does not dare to show weakness, nor is they willing to lag behind.

Because you are one step slower than people today, you may soon be a thousand or ten thousand steps slower, and when the resources of the asteroid belt are divided, you will only be able to cry and cry at the United Nations General Assembly, and completely lose the right to speak in space.

Once it lags behind in the new era, it is destined to become a second-rate country, and it will not be able to reap the slightest benefit in the future interstellar age of discovery.

Qin Yi's side sells the spaceship too expensive, the kind that doesn't sell a penny less than 5 trillion Chinese dollars, even if it is the craziest Japanese who reserves Chinese dollars, it is still a lot, a lot, let alone other countries.

There is no way, everyone can only be self-reliant, with these trillions of Chinese dollars, there is no problem in building 10 or 8 huge spaceships, and they can also cultivate their own scientific research team, engineer team, space shipbuilding capabilities, and drive the development of related industries in their own countries.

When it comes to settling accounts, everyone is a shrewd person, and no one is a fool.

Therefore, there are many people who come to Qin Yi to buy steel, all of them are representatives of one country, and all of them are ambitious, and they want to buy tens of millions of tons of steel.

Not long after Qin Yi's steel was smelted, 10 million tons today and 10 million tons tomorrow were quickly sold, and more than 200 billion Chinese dollars were recovered.

"All the plans are very good, but if you want to rely on traditional rocket technology to drive the spacecraft to mine asteroids, it should be no problem to mine asteroids of about millions of tons or tens of millions of tons of small ones, but if you want to mine large asteroids, hehe~"

In the spaceship headquarters building of Galaxy Technology Group, in Qin Yi's office, Qin Yi stood next to the window and watched the southern sticks leave, and the corners of his mouth couldn't help but laugh.

Traditional rocket propulsion technology, which relies on burning solid or liquid fuel to obtain powerful thrust, was the only way for humans to enter space before the advent of anti-gravity technology.

Rocket technology has a long history of development, the technology is very mature, and it has also made great contributions to the development of human space industry, but it is obviously not obvious that it wants to be used in the mining of asteroids.

When the rocket burns, the fuel will soon burn out, and it can still be used in short-range space voyages, and many of the spaceships that travel between the Earth and the Moon are now spaceships made by countries around the world that use rocket thrust.

Because the distance between the Earth and the Moon is short, only less than 400,000 kilometers, you can still walk by relying on the thrust of the rocket.

But to the asteroid belt, even the straightest distance from the Earth to the asteroid is more than one astronomical unit, and that is at least 150 million kilometers.

In fact, it is impossible to fly in a straight line, because the earth is rotating, and if you fly in a straight line, you will not be able to catch up with the earth at all, and you must go in the direction of the earth's revolution.

The one-way journey is much longer, more than 200 million kilometers casually, and at least 400 million kilometers round trip.

Such a long distance, although flying in space, only the start and deceleration need to use power, most of the time relying on inertial flight, but such a long distance, all kinds of situations may arise, relying on traditional rocket power technology is too unreliable.

If the calculations are accurate and everything goes well, it is still possible to mine the asteroid and come back, but the room for maneuver is relatively small, and the fault tolerance rate is very low.

Qin Yi believes that scientists in these countries should have repeatedly made detailed calculations on this, and they know very well that there is a great risk in this, but they have no choice, even if there is a risk, it is also necessary, because they can't lag behind others, and they can't watch the Chinese family dominate.

Scientists also believe that anything may not be good enough at the beginning, but with the progress of technology and the accumulation of experience, it can be slowly improved to reduce the risk, just like when the plane first appeared, the accident rate is extremely high, but now, the plane is the safest way to travel.

In the middle of space, Mt. Fuji Space City.

This is the largest space building built by the Japanese in space, it integrates scientific research, shipbuilding, tourism and many other functions, very large, very lively, can be regarded as the embodiment of the power of the Japanese in space.

"Ladies and gentlemen, for the sake of our brilliant future, in order to be able to lay a starry sky for our children and grandchildren, in the coming days, I hope that everyone can show 100% enthusiasm and strive to build the Kaguya spacecraft as soon as possible."

Jiro Omura, the chief engineer and chief designer of the Kaguya Project, said to a group of scientists and engineers.

"Hi~"

When everyone heard this, they immediately looked solemn, and immediately replied in unison very respectfully.

This is a very high action team, but also a very professional team, in order to build the Kaguya spacecraft, the entire project team has dispatched Japan's top scientists and engineers in various fields, a total of more than 100,000, plus relying on the strength of the whole country, hundreds of universities in Japan have participated, and tens of thousands of powerful companies have actively assisted, it is bound to build a huge spaceship that has attracted worldwide attention.

The shipyard where Mt. Fuji Space City used to build small spaceships has been stopped or moved to other places.

The steel purchased from the Galaxy Technology Group was transported by the spaceship, and the robotic arm from the Huaxia Ink Claw Machinery Technology Group became extremely busy.

The entire shipbuilding dock is almost a miniature version of the Dragon's Nest space factory, although I don't want to admit it, but in this era, in the development of the space field.

Not only Japan, but all countries around the world have been influenced by China, and they are all learning from China, whether it is the construction of space architecture, or the construction of spaceships, etc., everyone is learning, learning from China, learning from Galaxy Technology Group.

The same goes for the construction of the 'Kaguya' spaceship, because the Blue Dragon spaceship is so big that it was built in an exposed dock outside the Dragon's Lair Space Factory, directly exposed to space.

Countries around the world that are very concerned about this will naturally not give up a good opportunity to learn, so when the Qinglong spacecraft was built, countless pairs of eyes were staring at every moment, and the construction process was completely filmed with a camera.

Now that the 'Kaguya' spacecraft is to be built, the Japanese have also learned the process and steps of the Galaxy Technology Group's construction of the 'Blue Dragon' spacecraft, and then combined it with their own design to make some changes and modifications.

In just a few months, a huge keel appeared next to the Mt. Fuji Space City, although this keel is not as large as the Blue Dragon spacecraft, but its length has reached more than 800 meters, more than 300 meters long, and more than 100 meters high, it can be seen that this is definitely a very large spaceship.

At the same time, the two wings at the bottom of this spacecraft, there are several rows of rocket propulsion design, it is obvious that in terms of power, the Japanese did not design a single-power rocket thrust system, but adopted a safer and more secure multi-power system design, and also because of the use of a multi-rocket propulsion system, its power will be more powerful.
