Half-immortal civilization

(I also thought about whether to enlarge the pace and increase the progress of the plot; but I also have to consider, try to arrange it as reasonable as possible, don’t write science fiction as unreal, so the plot will be a bit slow, please forgive me. I think once it is really written as unreal , It is also an irresponsible behavior towards you.

Of course, Tianya here has the cheek to ask for collection and recommendation.Thank you.

In addition, in order to make the story more vivid and closer to reality, everyone is welcome to brainstorm. ) The plane and the comet are rapidly approaching at an angle of about 90 degrees. The comet, which was far away in the sky just now and can only be seen with the help of one, is now very close at hand.

"Now, launch!" Mu Xinghai's voice sounded.Afterwards, the speed of one of the Dream planes dropped significantly. However, only 10 minutes later, the comet that was about to leave in front of it suddenly shook violently. Covering an area of ​​tens of thousands of kilometers, with the burst of strong water vapor, it fell rapidly towards the direction of the sun.

At that moment, the chairman and the others all held their breath and looked at the extra-large fireworks in front of them, far surpassing the most beautiful and spectacular on earth. Under the sunlight, dots of colored light spots appeared among the water vapor and dust scattered in space, but These light spots are broken, which makes people feel a kind of sorrow of the broken world.

"This is technology, this is the electromagnetic railgun!" The chairman muttered to himself, looking at a huge celestial body 30 kilometers away. Such a celestial body can hit the earth, and it can destroy millions of square kilometers of celestial bodies. Under the attack of the No. [-] aircraft, it was easily turned into dust in space, leaving nothing behind, let alone the power to resist!

If you don't see it with your own eyes, you will never imagine that the electromagnetic railgun in space will be so terrifying.The comet that once threatened the safety of the earth just quietly disappeared into space.And at the last moment, walking through fragments of tens of thousands of kilometers, a hazy mist, that is a range larger than the earth, and it is really touching!
Everyone breathed a sigh of relief, looking at the spectacular scene that quickly went away outside the window.Unfortunately, the speed of the plane is too fast. After 10 minutes, you can only see the scene of the size of the moon, and after another 10 minutes, only the size of a saucer remains.

"We are now 180 million kilometers away from the earth, and we are starting to return. You can now observe the earth at this distance through the instruments on the plane.

Leaders, we are the first human beings to observe our earth with our own eyes at this distance! "

Mu Xinghai's words were a little excited.Yes, even the top pilots of the master company can travel around the moon in a few hours, but it is also the first time to observe the earth at this distance.

At this distance, the earth is just a white point of light.Yes, just a white spot of light, you can't even see the blue!
"This is the earth? It's so small!" The chairman suddenly sighed.

"Yeah, it's too small!" The face of Lao Liu next to him was already rosy, and he looked at the white light spot in the distant space, which was not as big as a litchi, and suddenly felt something, "We still have a long way to go. Let’s go. Perhaps, we are going to plan a long march in the space age!”

"Yes, that's a good idea!"

But at this time, Mu Xinghai once again disturbed everyone's interest: "Please note that the plane is starting to return and will make a sharp turn. The instantaneous acceleration may reach 3 times the gravity for a short time. Please be prepared."

It's 3 times the gravity again!Some people's faces turned pale, but they also knew that the plane was only flying forward just now, and now it was going to return to the earth, of course it had to turn around.

The engine roared, and the whole world was filled with the sound of the engine.When the speed is as high as 130 kilometers per second, it is not easy to turn a corner.

On the other hand, Mu Xinghai was also doing an experiment, slowly changing the direction of the plane through a slow side force, and in the process, keeping the speed of the plane unchanged.This is a very critical technology.

If the plane is in space, it has to decelerate to zero first, and then re-accelerate. This not only wastes a lot of time, but it will take at least an hour to re-accelerate.And once a war breaks out, this is a living target!

All the people lay down and fastened all the seat belts; and the plane began to slowly lift its head up, and began to return, preparing to make a 180-degree upward flip.

In the computer model, the plane will make a big turn with a diameter of up to 72 kilometers, while the diameter of the earth is only 1.27 kilometers!

But this kind of action is so inconspicuous in the vast space.

18 planes, in the absence of space, neatly raised their heads, neatly climbed, and neatly turned over...

If you judge acrobatics, it is definitely an unsurpassable peak in the world today!

After three full hours, the plane finally made a complete U-turn, and the speed, not only did not decrease, but increased a lot.This is mainly because, in the future, taking care of these elderly people will take a 10-minute break every half hour. During this period, only double the gravity will be maintained; and this has also caused the actual gyration diameter to exceed 100 million kilometers.

When the plane returned to the earth, it was already 4 hours later, and at a position of 30 kilometers away from the earth, the plane began to decelerate. When it approached the earth, the speed had dropped to 8 kilometers per second.

All the people were excited, looking at the blue planet so close, they suddenly felt an unprecedented shock and beauty.In the vast space, there is only such an earth!In this seemingly endless desert, there is only one bowl of water!That kind of preciousness, that kind of shock, made everyone shed tears for a moment.This is our foundation!

"Next, we will revolve around the earth three times. Of course, if the leaders feel that three times are not enough, we can do three more times." In a rare way, Mu Xinghai made a small joke, "We still have 50% of the battery left. It can hover over the earth for a few days."

"Then circle a few more times and let me take a good look at the earth." Suddenly, the chairman also began to playful, "People say that watching is a bad habit, but today, I think we are watching the earth!"

"Pfft!" Zhang Jingyuan in the monitoring center on the ground spewed out a mouthful of water.Well, great idea, watch the earth!

At this moment, some segments of the simultaneous live broadcast have already made Huaxia boil.For example, the 100 million-kilometer slalom makes everyone excited and overwhelmed.

However, Huaxia's actions here have made other countries worry. Without him, the gap in technology is really too big!In particular, satellites in space tracked the entire journey of the plane.As a result, the once developed countries were completely silenced.

However, what made them speechless even more was what was yet to come!
