On July 3, 2020, this huge ship that had been staying in the solar system suddenly ejected a pulse stream, which instantly crossed a length of dozens of kilometers, making the dark space suddenly light up.

Immediately after, the heavy body of the spacecraft began to move slowly, and after ten minutes, it had easily broken free from the gravitational pull of the sun, sailed away from the ecliptic plane, and gradually flew towards the outer solar system.

……

One early morning on Earth.

In the middle of a piece of ice and snow, a metal plate that was frozen on the ground suddenly shook slightly, making a clattering sound, and it didn't take long for it to be knocked open by a huge force, and a figure cautiously drilled out of the hole, blown by the cold wind outside, and he shivered.

Five years have passed since the destruction of the aliens, the sky is much brighter than it was at the beginning, and the temperature has warmed up significantly, but it is still minus 34 degrees.

He rubbed his hands together and sneaked out of the cave, this man was wrapped in a thick animal skin, with a foul smell on his body, and his face was covered with thick dirt and greasy, which made it impossible to see his true face, as if he had not bathed for years.

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

He glanced up at the sky covered by lead clouds, and his eyes, which were already pitch black, suddenly became deeper, a kind of darkness that humans could not describe in words, as if even the light could not escape.

He looked at it for a while, and suddenly his face was stunned, as if he didn't believe it, rubbed his eyes, and stared at it for a few minutes, his expression became more and more excited, and his body began to tremble slightly.

He ran to the cave with a roll and a crawl.

"Gone, finally gone!" As he ran, he shouted, his voice full of excitement and crying, like a madman.

"What, gone, you read that right?"

"Really gone?"

"Okay, good, we're safe!"

Surprisingly, there were not many people in the cave inside, but the small cave ** part was crowded with people, and when I heard that this person was disappearing, the atmosphere was suddenly boiling.

"Everyone, calm down, Xiaohu, drink saliva first and speak slowly!" A burly middle-aged man stepped out of the crowd and patted him on the shoulder: "What do you see?" ”

He was tall, athletic, with a thick chest and a great sense of strength, but he was rather quiet and spotless compared to the rest of the men, and as he spoke, the whole cavern fell silent.

If Luo Yuan was here, he would recognize that this was Ling Zhong'an, the former deputy minister of the Sword Headquarters.

It's also fatal to say, when the Boxing people's plan to destroy humanity was launched, he lived in the Sword Headquarters in the suburbs, and when the antimatter bomb exploded, it was directly affected by the destructive force, and his body was instantly shattered.

Fortunately, his evolution ability is special, his body can be decomposed into particles in a short time, and to some extent he is already close to immortality, at the moment of shattering, the body began to reorganize at the same time, and in addition, it was far away from the center of the explosion, so he picked up a life, but he was also severely injured, and he was in a coma for more than a year before he woke up from the ice.

It's a pity that the large army of humans has long left the earth at that time, and he can no longer find traces of human activities, and wanders in the ice field for half a year before he accidentally finds the footprints left by humans and finds this wanderer camp.

The man known as Xiaohu took a sip of water and calmed down: "Boss, that alien spaceship is gone, it's really gone." ”

The originally quiet crowd became excited again, and many people were already crying with joy, they have been hiding in Tibet for several years, and every time they are active, they will choose the coldest night, lest they be found by aliens and purged again, for which many people have frozen to death.

"Don't be careless, maybe it's hidden behind a planet, we've been waiting for five years, don't care about waiting for another year and a half, now the weather has warmed up, the food has become more and more abundant, as long as it is not discovered by aliens, cut the grass and eradicate the roots, enough for us to survive."

……

The solar system is extremely extensive, bounded by the Kuiper Meteorite Belt, a circular space with a diameter of one light year, in which the influence of the sun's gravity is relatively dense with matter and gas, and belongs to the high-risk area of interstellar navigation.

However, even if it was kept safe at a low speed, the spacecraft still did not fly so smoothly, and almost every few hours, the spacecraft experienced a slight shock.

A large amount of those fine dust in space frequently bombarded the spaceship, causing the spacecraft to emit a misty glow while flying.

At the beginning, every shock will cause people to be anxious, but after more experience and time, they will gradually get used to it.

Fortunately, the farther away from the Sun, the less frequent the oscillations became, and after three years, it only happened once in a while, and when it was out of the solar system, it didn't happen again.

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

In the past decade, the latest generation of quantum computer groups has replaced the original computer groups, and the computing power has increased tens of thousands of times, making the world more vast and more realistic.

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

Not only are there factories on the island, but there are also factories in space.

At this time, in a huge factory, the construction of a new spaceship has officially started.

The lower and upper two super giant gantries on both sides stand tall, and with the assistance of a large number of construction machinery around, the two gantries are hanging on both sides of the giant arc-shaped armor weighing billions of tons and slowly closing.

Luo Yuan and a group of high-level people rode on a small flying machine, watching the armor in the distance gradually close, just looking from afar, you could feel the shock from the bottom of your heart,

The length of these two gantries is more than 10,000 meters, the height is also 5,000 meters, and the total mass is 1.5 billion tons.

With such a huge gantry, this spaceship that is about to be built is naturally not small. Compared with this planned spaceship, the small flying machine that Luo Yuan was more than ten meters long was like a fly next to an elephant, and it looked insignificant.

The spacecraft is still saucer-shaped, but it is an astonishing nine kilometers in diameter, six times the size of the mothership, and it would take at least two hours for someone to walk from one end to the other. And its mass can reach 10 billion tons.

This spaceship is not a copycat of the Boxing mothership modeled on humans, nor is it simply enlarged, but a new generation of design of a new interstellar warship. The reason why the spaceship is still saucer-shaped is not that humans do not have the technical strength to make spaceships with other shapes, but because there are not many spacecraft shapes to choose from, although the spaceship is in a bad space environment, under normal circumstances, it is not too close to the stars, and it is very little affected by gravity, and it seems that any structure can be.

However, this is only for the spacecraft in a stationary situation, the spacecraft also needs to accelerate or decelerate, and even in case of emergency, it will slow down sharply, so the stability of the spacecraft structure is quite high.

It must be symmetrical up and down, left and right, and maintain a balance of mass everywhere, which eliminates those odd-shaped structures, and at the same time, the contact surface should be smaller and faster when flying, reducing the probability of hitting the meteorite head-on.

In addition to being larger, its scientific and technological content is far beyond the glass star mother ship, in recent 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 development speed.
