Epoch of Twilight

On 2020, on the third day of July, this behemoth, which has been stuck in the solar system, suddenly ejected a pulse stream and instantly crossed the length of tens of kilometers, making the dark space suddenly brighten.

Immediately afterwards, the heavy body of the spacecraft began to move slowly. After ten minutes, it had easily escaped the gravitational pull of the sun, drove away from the ecliptic plane, and gradually flew outside the solar system.

......

Some morning on the earth.

In a piece of ice and snow, a piece of metal plate that was frozen on the ground suddenly vibrated slightly and made a squeaking sound. It was not long before it was knocked open by a giant force. A figure carefully drilled out of the hole and was chilled by the outside. Blowing, he took a nap.

It has been five years since the destruction of aliens. The sky has been brighter than it was at the beginning, and the temperature has returned to a large temperature, but it is still minus 34 degrees.

He licked his hand and sneaked out of the hole. The man was covered in thick animal skin, with a stench on his body, thick mud and greasy face, which made people unable to see his true face. I haven’t taken a shower for years.

However, a pair of dark eyes that are different from ordinary people show that he is not an ordinary person.

He looked up at the sky covered with lead clouds, and the already incomparably dark eyes suddenly became deeper. This is a kind of darkness that humans describe without words, as if they could not escape the light.

He looked at it for a while, and suddenly looked awkward. He seemed to still believe it. He blinked and looked at it for a few minutes. His face became more and more excited and his body began to tremble slightly.

He ran to the cave with a roll of climbing.

"Go, finally left!" He yelled as he ran, his voice full of excitement and crying, as if he was a madman.

"What, gone, you are not mistaken?"

"Really gone?"

"Good, we are safe!"

Surprisingly, there were a lot of people in the cave, and the small hole was filled with people. When I heard this person disappeared, the atmosphere suddenly boiled.

"Everyone calms down, Xiaohu, drink water first, and slowly say!" A tall, middle-aged man came out of the crowd and patted him on the shoulder: "What did you see?"

He is tall, physically strong, and has a strong chest. He is full of powerful sense of power. Compared with the rest of the people, he looks quite clean and his body is spotless. As he speaks, the whole cave is quiet.

Strong strength, let him become the natural boss of this wanderer camp, no one dares to challenge his authority.

If Luo Yuan is here, he will recognize that this is Ling Zhongan, the deputy director of the former Li Jian headquarters.

It is also hard to say. When the Bolivia’s plan to destroy humanity was launched, he lived in the headquarters of the Lijian in the suburbs. As a result, the devastating force was directly affected by the anti-material bomb explosion, and the body shattered instantly.

Fortunately, his evolutionary ability is special, the body can be decomposed into particles in a short time, and to some extent it is close to immortality. At the moment of smashing, the body begins to recombine at the same time, and further away from the center of the explosion, it is paralyzed. One life, but also severely hit hard, he was in a coma for more than a year before he woke up from the ice.

It is a pity that at that time, the large army of human beings had already left the earth. He could no longer find traces of human activities. After wandering for half a year in the ice sheet, he unconsciously discovered the footprints left by human beings and found the camp of the wanderers.

The man, known as Xiaohu, drank his mouth and calmed down his mood: "Boss, the alien spaceship, has disappeared, really disappeared."

The quiet people were excited again. Many people have been so happy that they have been hiding in Tibet for the past few years. Every time they move, they will choose the coldest night, for fear that they will be cleaned again by aliens. Few people.

"Don't care, maybe it is hidden behind a certain planet. We have waited for five years. I don't care to wait another year and a half. Now the weather has warmed up and the food is getting richer, as long as it is not alien. People have found that weeding the roots is enough for us to survive."

......

The solar system is extremely wide, bordered by the Kuiper meteorite belt. This is a circular space with a light-year diameter. In this area, due to the influence of solar gravity, the matter and gas are relatively dense, which is a high-risk area for interplanetary navigation.

But even if it is kept at a low speed and safe state, the spacecraft is still not so stable when flying. During this time, the spacecraft will have a slight shock almost every few hours.

A large number of tiny dust in space frequently bombarded the spacecraft, causing the spacecraft to shine in flight.

In the beginning, every shock will cause people's anxiety, but they will experience more, and after a long time, they will gradually get used to it.

Fortunately, the farther away from the sun, the lower the frequency of the shock. After three years, it has only happened once, and when it leaves the solar system, this situation has not happened.

Time flies, and today the spacecraft has been flying in space for nearly a decade.

Today's virtual world is no longer the narrow world of the past. In this decade, the latest generation of quantum computer groups replaced the original computer group, and the computing power has increased tens of thousands of times, making the world more extensive. It has also become more real.

This space island has become a large island with an area of ​​more than 10,000 square kilometers.

Not only is the factory on the island dense, but even the space has appeared in the factory area.

At this time, a new spacecraft construction project in a giant factory has been officially launched.

The two upper and two super-sized gantry frames on both sides stand tall, and with the help of a large number of construction machinery around them, the two gantry frames are erected on both sides and the giant curved armor weighing several billion tons is slowly closing.

Luo Yuan and a group of high-rise passengers took a small flying machine and watched the armor of the distance gradually close together. It was a long-term wait and see, and you could feel the shock from the bottom of your heart.

These two gantry frames have a length of more than 10,000 meters, a height of five kilometers, and a total mass of 1.5 billion tons. They are placed on the earth. Such a super machine, even if the metal process of the Bolivia is completely impossible, the light is gravity. It can be crushed, in order to drive it specifically, the power consumed per second reaches 10 million degrees, almost comparable to the mother ship.

With such a huge gantry, the ship that is about to be built is naturally not too small. Compared with this planned spacecraft, Luo Yuan’s small aircraft, which is more than ten meters long, seems to be insignificant.

The shape of the spacecraft is still dish-shaped, with a diameter of nine kilometers, six times that of the Bose mother ship. If someone walks from one end to the other, it will take at least two hours. And its quality can reach 10 billion tons.

This spaceship is not a copy of the human-like model of the B-Star Mothership, nor is it a simple enlargement, but a new generation of Star Warships designed by the new generation. The reason why the spacecraft is still in the shape of a dish is not that the human body has no technical strength to make other shapes of the spacecraft. It is because there are not many options for the shape of the spacecraft. Although the spacecraft is in a space environment, in general, it is not too close to the stars. The impact of gravity is small, and it seems that any structure can be.

However, this is only for a spacecraft in a static situation. The spacecraft also needs to accelerate or decelerate. Even in an emergency, it will decelerate rapidly, so the stability requirements of the structure of the spacecraft are quite high.

It must be symmetrical up and down, and the quality of each place is balanced, which eliminates those grotesque structures. At the same time, the contact surface should be smaller and faster when flying, reducing the probability of hitting the meteorite on the face.

In addition to its larger size, its technological content is far beyond the Boseidon mother ship. Over the past few years, human science and technology have advanced by leaps and bounds, and a large number of new technologies and new achievements have emerged, showing an explosive growth rate.
