Epoch of Twilight

In 2020, on July 3rd, this behemoth that had been staying in the solar system suddenly ejected a pulse stream that spanned tens of kilometers in an instant, making the dark space suddenly brighten up.

Immediately afterwards, the heavy body of the spaceship began to move slowly. Ten minutes later, it easily broke free from the sun's gravitational pull, left the ecliptic plane, and gradually flew out of the solar system.

...

One morning on Earth.

In a world of ice and snow, a metal plate that was frozen on the ground suddenly vibrated slightly, making a bang bang bang sound. After a short while, it was knocked away by a huge force, and a figure carefully drilled out of the hole. Blow, he shivered all over.

Five years have passed since the destruction of the aliens, the sky has become much brighter than before, and the temperature has also risen significantly, but it is still minus thirty-four degrees.

He rubbed his hands, and sneaked out of the cave entrance. This man was covered in thick animal skins, with a stench on his body, and his face was covered with thick dirt and greasy, making it difficult to see his true face clearly. It felt like I hadn't showered in years.

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

He raised his head and glanced at the sky covered by lead clouds. His eyes, which were already extremely dark, suddenly became darker. This is a kind of darkness that humans can't describe in words, as if even light cannot escape the eyes.

He looked at it for a long time, and suddenly his face froze, as if he still couldn't believe it, he rubbed his eyes, stared at it for a few minutes, his expression became more and more excited, and his body began to tremble slightly.

He scrambled and ran towards the cave.

"Let's go, finally go!" He shouted while running, his voice was full of excitement and crying, like a lunatic.

"What, let's go, you read it right?"

"Really gone?"

"Okay, okay, we're finally safe!"

Unexpectedly, there were not many people in the cave, the small cave was full of people, and when they heard that this person disappeared, the atmosphere suddenly boiled.

"Calm down, everyone, Xiaohu, drink some water first, and speak slowly!" A middle-aged man with a strong figure stepped out and patted him on the shoulder: "What did you see?"

He was tall, with a strong physique, a thick chest, full of a strong sense of strength, compared with the rest of the messy people, his body was quite clean, spotless, and as he spoke, the whole cave fell silent.

His powerful strength made him the natural boss of this homeless camp, and no one dared to challenge his authority.

If Luo Yuan were here, he would have recognized that this was Ling Zhongan, the former deputy head of the Sword Headquarters.

It is hard to say, when the Boxing people's plan to destroy human beings was launched, he lived in the headquarters of the sword in the suburbs. As a result, when the antimatter bomb exploded, he was directly affected by the destructive force, and his body was instantly shattered.

Fortunately, he has a special evolutionary ability, his body can be broken down into particles in a short time, and he is already close to immortality to a certain extent. The moment he is shattered, his body begins to reorganize at the same time. In addition, he is far away from the center of the explosion, so he picked up One life, but he was also seriously injured. He was in a coma for more than a year before waking up from the ice.

It's a pity that at that time, the human army had already left the earth, and he could no longer find traces of human activities. After wandering in the ice field for half a year, he accidentally found the footprints left by humans and found this homeless camp.

The man called Xiaohu took a sip of water and calmed down: "Boss, that alien spaceship is gone, really gone."

The originally quiet crowd became excited again, and many people were crying with joy. They have been hiding in Tibet for the past few years. Every time they do activities, they will choose the coldest late night, lest they will be discovered by aliens and be cleaned again. For this reason, they have froze to death Few people.

"Don't be careless, maybe it is hidden behind a certain planet. We have been waiting for five years, and we don't care about waiting another year or a half. Now the weather has warmed up and the food has become more and more abundant. Man discovered that cutting the weeds and rooting them out was enough for us to survive."

...

The scope of the solar system is extremely vast, bounded by the Kuiper meteorite belt, which is a circular space with a diameter of one light-year. In this area, affected by the gravity of the sun, matter and gas are relatively dense, which belongs to the high-risk area of ​​interstellar navigation.

But even if the low-speed safety state has been maintained, the spacecraft is still not so stable when flying. During this period, the spacecraft will experience a slight shock almost every few hours.

A large amount of fine dust in space frequently bombarded the spaceship, causing the spaceship to emit a hazy brilliance even in flight.

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

Fortunately, the farther away from the sun, the lower the vibration frequency. After three years, it only happened once in a while, and after leaving the solar system, this kind of situation never happened again.

Time flies, and the spacecraft has been in space for almost a decade now.

Today's virtual world is no longer as narrow as it used to be. In the past ten years, the latest generation of quantum computer groups has replaced the original computer group, and its computing power has been increased tens of thousands of times, making this world even bigger. It also becomes more real.

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

Not only is the island densely covered with factories, but even in space, there are stretches of factory areas.

At this time, in a giant factory, a new type of spaceship construction project has officially started.

The lower and upper two ultra-giant gantry frames on both sides stand tall. With the assistance of a large number of construction machinery around, the giant curved armor weighing billions of tons on both sides of the two gantry frames is slowly closing.

Luo Yuan and a group of high-level executives rode a small aircraft and watched the armor gradually close in the distance. Just by watching from a distance, one could feel the shock from the bottom of his heart.

These two gantry frames are more than 10,000 meters long, 5,000 meters high, and have a total mass of 1.5 billion tons. Putting it on the earth, such a super machine is completely impossible even with the metal crafts of the Boxing people. Gravity alone , it can be crushed, and in order to drive it exclusively, the power consumed per second reaches 10 million degrees, which is almost comparable to that of the mother ship.

Using such a huge gantry, the spaceship to be built is naturally not small. Compared with this planned spaceship, Luo Yuan's small flying machine with a length of more than ten meters is like a fly next to an elephant, and it looks insignificant.

The size of the spaceship is still a dish-shaped structure, but its diameter reaches an astonishing nine kilometers, which is six times that of the Bossing mother ship. If someone walks from one end to the other, it will take at least two hours. And its mass can reach tens of billions of tons.

This spaceship is not a copycat of the Boxing mother ship, nor is it simply enlarged, but a brand new interstellar warship designed by a new generation. The reason why the spaceship is still in the shape of a disc is not because humans do not have the technical ability to manufacture spaceships of other shapes. It is because there are not many spaceship shapes to choose from. Although the spaceship is in the environment of space, under normal circumstances, it will not be too close to the stars. Little affected by gravity, it seems that any structure will do.

But this is only for a spacecraft in a stationary state. The spacecraft still needs to accelerate or decelerate, or even decelerate rapidly in an emergency. Therefore, the stability requirements of the spacecraft structure are quite high.

It must be symmetrical up and down, left and right, and the mass must be balanced everywhere, which excludes those strange structures. At the same time, when flying, the contact surface must be smaller and faster to reduce the probability of head-on collision with meteorites.

In addition to being larger in size, its technological content far exceeds that of the Boxing mothership. In the past few years, human science and technology have advanced by leaps and bounds, and a large number of new technologies and achievements have emerged one after another, showing an explosive development speed.
