"I announce that the Mars transformation program has officially entered the engineering stage, and the countdown to the launch of the Mars transformation fleet has begun." At the end of the Mars Transformation Plan press conference, the Emperor of the Ming Empire, who was standing in the middle, announced the start of the Mars Transformation Plan, and the fleet was officially launched.

With the emperor's order, Zhu Lei, who was already in the chess world, also began to give the order to take off.

With Zhu Lei's order, the captains of a small fleet and the captains of each battleship also began to give orders to take off at the same time.

"Battleship increases the power of the anti-gravity engine!"

"Start the plasma thruster"

As all the battleships started their engines, the battleships began to move slowly, flying into space one after another.

A battleship lined up in a neat line and flew into space in an orderly manner.

And the speed of the battle ranks is getting faster and faster, and in the end it turns into a little bit of starlight, and after entering the universe, each battleship immediately starts the artificial gravity engine.

After leaving the moon, the spacecraft turned on the fusion engine, and the plasma thrusters produced more energy to speed up the spacecraft, and the fleet began to accelerate continuously, and the slowest warship in the entire fleet could reach 4% of the speed of light if it sailed at full speed.

However, the fleet does not have to use such a fast speed in the solar system, so when the speed reaches about 120 kilometers per second, all the ships in the fleet turn off their engines.

Although 120 kilometers per second seems to us to be quite fast, in the context of the universe, the very actual speed seems to be slower than that of a turtle, and it is impossible to tell whether the spacecraft is flying or not.

Watching the spaceship go away, all the people on the scene cheered loudly, after all, this fleet is the only space fleet of mankind at present, and it is also the only security guarantee for mankind now, it is with the existence of this fleet, human hearts have the bottom, before the completion of this fleet, although the force of the Ming Empire is already very strong in the eyes of the earthlings, but in fact, all people have no bottom in their hearts, after all, there are many civilizations in the universe with a higher degree of science and technology than human beings, and I don't know when it will come.

With the existence of this fleet, if an alien civilization comes, human beings also have the force to fight, and no matter what, they can at least buy time for human beings to transfer.

At this time, in Xiaolu's live broadcast room, netizens were also frantically swiping the screen.

"Wow, it's shocking, modern human beings finally officially have their own space fleet, I can't imagine that since human beings walked out of the earth, it has only been a short 20 years to have their own space fleet, although this space fleet may not be very powerful, but at least it can provide us with a strong security guarantee."

"Yes, who says it's not, and according to the data, the flagship of this space fleet, blasting the earth is like playing, this is the power of technology!"

……

Zhu Lei stood in the command room of his flagship, looking at the earth gradually disappearing in the distance.

He knew that from today onwards, mankind was about to turn a new chapter, because just now, at the moment when his space fleet was launched, the little Lori in his super plane mall reminded him that the earth civilization had finally successfully entered the threshold of the intermediate civilization and became an authentic middle polar civilization.

And the list of sales in the mall has been updated, and all the goods sold in it have become products of intermediate civilization, and he has also seen many scientific and technological products that are useful to the earth in it, but because they are all products and technologies of intermediate civilization, these things are very expensive, and with his current net worth, even if they all add up, it is not enough to buy a scientific and technological technology.

He used to think that it was very cost-effective to sell food in the mall, after all, an average of one energy coin and a pound of grain seemed very expensive to him before, but now after upgrading, he found that selling food is actually a very stupid thing, because after reaching the intermediate civilization, selling scientific and technological products is the mainstream, because casual scientific and technological products require millions or even tens of millions, and some even require hundreds of millions or billions of energy coins. So how much grain needs to be sold to buy a technological product.

After all, relatively speaking, compared to the primary civilization, the intermediate civilization already has its own scientific and technological development direction, and it is very unrealistic to use products to control an intermediate civilization, and after the intermediate civilization, many technologies are very similar, and some can even be imitated directly, which is what we call a cottage.

Therefore, Zhu Lei is not going to sell food in the mall in the future, not to mention that with the passage of time, the price of food on the earth will become higher and higher, not to mention that with the increase in population, it may even be that even the food of human beings themselves is not enough, let alone sell it in the mall, so he has to choose to sell the products again.

Although the pig man had also sold some technological products before, most of these technological products were low-end technological products, and the civilization level he was in before was only primary, and the price of the same product was much lower in the primary civilization, so it was only now that he found out why the technological products of the intermediate civilization were so few in the primary civilization.

Although the intermediate primary civilization is only a little higher than the primary civilization, the intermediate civilization is the middle pole civilization after all, and there is an essential difference between the primary civilization, after all, one is just struggling on its home planet, and some have even been able to dominate one side, especially in terms of resources, the primary civilization and the intermediate civilization are not comparable at all.

Zhu Lei saw at a glance in the mall, there were all kinds of minerals for sale everywhere, and there was a lot of grain for sale, although the turnover was also very large, but compared with scientific and technological products, the price of these grains was really not enough.

However, there are a lot of scientific and technological products that are sold, especially industrial products, in the mall, and most of the prices of these products are around several million, after all, most of the intermediate primary civilizations have just been promoted from the primary civilization, so the scientific and technological content is not very high for civilizations of the same level.

Walking around the mall, he found that there was one thing in the city that was very popular, and the price was good, and this kind of goods were also consumables, basically every civilization had to use them, and the most expensive of such goods was even higher than those industrial products such as high-end machine tools, that is, arms.

After all, compared to most other civilizations, the location of the earth civilization is too remote, and it can even be said to be a barren area of civilization, so compared to most of the other intermediate and elementary civilizations, the earth is obviously much more difficult on the road of civilization development due to being lonely in the barren area, but in terms of security, it is incomparable to other intermediate civilizations.
