This time, Zhu Lei stayed in the capital for a week, and then he returned to the moon and returned to the site of the Mars program demonstration meeting.

However, when Zhu Lei returned to the scene of the demonstration meeting, his company also made a big move at this time, at this time Zhu Lei's company is no longer the company more than ten years ago, and now his Yongan Military Factory is very famous in the entire Ming Empire, after all, many things in the Ming Empire can only be produced by his factory, and other factories cannot produce.

This time, Zhu Lei's company's big move was to announce that five plasma thrusters and three anti-gravity engines would be open to the people of the Ming Empire.

That is to say, no matter who it is in the future, as long as you are a citizen of the Ming Empire with your ID card, you can buy plasma thrusters and anti-gravity engines in his military factory with your ID cards, it can be said that from now on, plasma thrusters and anti-gravity engines are no longer exclusive products of the military, and anyone can buy them in the Ming Empire as long as you have money in the future.

And because these products are relatively early products, the prices are not very high, and even ordinary citizens of the Ming Empire can afford them.

Among them, the cheapest is the Ion 5 thruster, which is an ultra-small thruster, which was used as a steering device and brake device for spaceships more than ten years ago, but now due to the upgrading of Zhu Lei's military factory technology, this plasma thruster has been eliminated.

Therefore, this thruster is only used by civilian spaceships now, but before that, these spaceships used by the people of the Ming Empire were basically made by state-owned shipyards, and of course there were also his own shipyards.

However, from now on, due to the opening of plasma thrusters and anti-gravity engines to the people, the space shipbuilding industry is no longer the territory of the military and Zhu Lei.

In the future, the Ming Empire will be the same as the Age of Discovery, as long as you have the technology and capital, anyone can invest in the space shipbuilding industry.

If someone has strong hands-on ability, he can even build his own spaceship, and after passing the detection of the Ming Empire Security Testing Center, he can even drive the spaceship he made into space.

When Zhu Lei's military factory has announced the open purchase policy, all the people in the entire Ming Empire are inspired, especially those enterprises or individuals engaged in the shipbuilding industry 20 years ago, after all, after the rise of suspension cars and suspension trains, their shipbuilding industry has been dealt a fatal blow, although there is national support in the next ten years, most of the enterprises have been maintained, but it is also very sleepy, after all, after human walking after the space age, the surface ship shipbuilding industry on the earth has come to an end.

Although some countries have survived in the past ten years, the heads of these enterprises are very clear that if they do not make changes, then there is only two words waiting for them, and there is no way out.

However, the policy announced by Yongan Group this time is that these shipbuilding industry enterprises that are about to go bankrupt see the future, so when Yongan Group has announced the policy, they will immediately come to the door, after all, they have had enough of such days, so they know very well that if their shipbuilding enterprises want to survive in the universe age, they must follow the trend to the universe.

Although they knew it very well before, but they didn't have their own technology, so they could only watch, and now that the opportunity comes, of course they have to rush over immediately.

After all, in the previous ten years, although they did not have their own thruster technology and experience in manufacturing spaceships, but with their own company's experience in manufacturing surface ships decades ago, they also designed a large number of spaceship drawings in the past ten years, but because they did not have their own technology, these spaceships all stayed on the drawings and could not be manufactured.

However, their hard work was not in vain, and now they have finally waited for Yongan Group to open up the right to buy engines and anti-gravity engines.

In fact, this time, his Yongan Group announced the decision to let go of the right to buy, Zhu Lei personally made it, although it said that this would make their own company, as well as the state-owned shipyards will suffer great losses, and will definitely be occupied by these private shipyards Part of the market, but this is also a helpless thing.

After all, if human beings want to walk the universe era, spaceships are an indispensable means of transportation, whether it is war, or interstellar exchanges, or mining in the universe, there are a large number of spaceships, and so many spaceships, relying only on state-owned shipyards and Zhu Lei's own shipyards can not meet the needs of the entire Ming Empire.

And whether it is his own shipyard or a state-owned shipyard, it is mainly to manufacture war machines, that is to say, to manufacture warships, so for a long time in the future, whether it is his own shipyard or the state-owned shipyard of the Ming Empire, there is no energy to manufacture various spaceships for civilian use.

Therefore, it is necessary to open the right to purchase, and this opening is a product more than ten years ago, which actually has little impact on his own company, after all, his Yongan Group is mainly based on the military industry.

Although there is a big gap between the spaceships made by these private shipyards in terms of safety compared with Zhu Lei and the spaceships produced by state-owned shipyards, it is enough for the people.

The five thrusters that Yongan Group opened the right to buy this time are, two small thrusters, and two kinds of thrusters used in the Suzaku 1 and Suzaku 2 aerospace vehicles 20 years ago, the third plasma thruster is an ultra-miniature thruster, in fact, this is also the steering gear of the spacecraft, the fourth thruster is a large thruster, which is mainly used in large spaceships, and the fifth thruster is the thruster used in the steering of large spaceships mentioned above.

The three anti-gravity engines also cover the anti-gravity engines used by the three types of small, medium, and large spacecraft.

And Zhu Lei's Yongan Group, in addition to opening these two engines, even opened the earliest artificial gravity device, although this artificial gravity device, the volume is much larger than now, and the mass is also much heavier, and the gravitational force generated can only reach 2/5 of the current earth, but it is enough for the people at this stage.

It can be said that Zhu Lei's Yongan Group dropped a huge bomb on the entire Ming Empire this time, which made the entire lifeless shipbuilding industry of the Ming Empire change all of a sudden, and became very active, and even some shipyards have begun to publicize the spacecraft drawings they designed in the early years without buying plasma thrusters and anti-gravity engines and other equipment.

Some shipyards have even begun to lay dragons, and it can be said that they have been waiting for this day for nearly 20 years, and today they have finally waited for it.
