In 2020, the world's top scientists discovered wave crystals in the "Technology Forest". The "Technology Forest" was the last forest created by humans. Due to the large number of Due to the development and utilization, there are not many real forests left in the world. Wave Crystal is the only survivor from a distant wind-like planet. Its arrival has further confirmed the fact to mankind that a devastating disaster - the Devouring Empire is marching towards the Earth!

At this time, The wave crystal floated transparently in the air, and a cute girl appeared inside. She shouted: The army of the Devouring Empire is approaching here, it has destroyed our home, and ate what is left of us. A little bit of precious material, no matter how advanced our technology is, can't protect a piece of land, so run away! The further away, the better, its speed is amazing, and in a few decades, it will swallow the earth!!

After hearing what the little girl said, everyone was dumbfounded! The home they depended on for survival was about to disappear! "Why, we didn't provoke the Devouring Empire, why did they eat us!" humans roared angrily.

"Hey!" I could only hear the sigh of the little girl in the wave crystal! "How beautiful our home is! There are a few snow-white clouds floating in the blue sky, with thick trees and lush grass, and the air is so beautiful. So pure, so natural, the water is so bright, so thorough!

However, we are very stupid and greedy to use these natural resources, continue to exploit and seize them, so that in the end we can’t even get a tree. It is difficult to find intact trees, and at this moment, the Devouring Empire will take advantage of our current situation to violently attack us. What it fears most is the most pure natural resources, and when we lose the most precious things

It took advantage of our shortcomings and swallowed up our planet. After chewing day and night, it absorbed all the nutrients and available substances in the planet. About 100 years later, it spit out the remnants of the planet again. There was smoke everywhere, bare land, and erupting volcanoes, which completely restored our planet to its most primitive state. And I am the one on this planet. The only survivor!"

After listening to the little girl's narration, everyone was dumbfounded - the earth is about to be destroyed, it is our own fault, and now it is too late, too late to remedy it, it is ourselves Their ignorance led to disaster, and everyone sat there waiting for the moment of death, because they knew that the "decades" the girl said were only a few days away now!!

Is she also a robot? "Kid, you Is it also a robot?" I asked curiously. The little girl rolled her eyes at me and said, "Are you from Mars? People here are all robots." After that, the little girl left. I was left alone there in a daze, and instantly I felt like I was struck by thunder.

When the Pacific Plate 3 and Eurasia 15 When the tectonic plates docked and came together, the earth ushered in total darkness for the first time in 4.5 billion years. The twilight line disappeared and only the lights of the city remained bright. This process was witnessed by approximately 9 billion people in the solar system.

At first, just like a cloudy day, the sun seemed not as bright as usual, not as invisible as usual. After 30 minutes of cloudy skies, the docking began. Just like a total solar eclipse, the outline of the sun was covered little by little by a huge black screen, but the black screen was closed from both sides, like a burning red sun that was being squeezed. Blazing iron. This process lasted for two hours, and the brightness of the sun weakened little by little. Finally, night fell, the night sky became dark, and even the moon disappeared, leaving only a few stars. This is the sunset of the solar system.

The original theory of the Japanese Shell Project was proposed by Friesen as early as the 1960s. Dyson proposed. He envisioned an artificial celestial body with a diameter of about 200 million kilometers that would be used to wrap around stars and mine stellar energy. This is a natural nuclear fusion reactor that uses stars as a power source. In just 400 years, humans began to turn this theory into reality - the Sun Shell Project was launched.

The first phase of the solar shell project has been going on for 42 years. People have built several assembly docks as huge as cities in the orbits of Mercury, Venus and Mars. They are called "stellar factories".

Immediately afterwards, the second phase of the Sun Shell project lasted for 2 centuries. During this period, it provided 50% of the jobs in the solar system. Hundreds of millions of people lived and worked in the star factory, building the "solar shell" - used to surround and wrap around the sun, about 100 meters away from the sun. A giant man-made celestial body located 9 million kilometers away.

The solar shell is divided into hundreds of parts for construction. The built solar shell is transported to the nearest orbit for final assembly. Nearly 200 solar crusts cover about 50% of the sun's surface. Because they are like the major plates floating on the earth, these solar crusts are named various earth plates. Each solar crust has an area of ??about 15 billion square kilometers and is 10 kilometers thick. The side facing the sun is equipped with high-efficiency photovoltaic panels to absorb the radiant energy emitted by the sun, while high-strength carbon nanotube materials keep them structurally stable.

The solar crust will absorb 1.5 trillion joules of energy per second, which is 550,000 times the combined power generation of other facilities in the solar system.

Finally, in the third phase of the solar crust project that lasted for 58 years, a continuous space city was built on the outer surface of the solar crust, with an area 6,000 times that of the earth, and billions of people migrated to their new homes. .

At this point, the most massive and miraculous solar crust project in human history has been completed, which has made it possible for human civilization to further expand and develop.

My grandfather and father were both workers in the second phase of the Japanese Shell Project. Whenever my grandfather talks about the past, he will always proudly tell me that he participated in the construction of the first sun shell. And I live in Asia City No. 15, Eurasia, and am engaged in the work of maintaining the sun shell.

I am sitting in a construction vehicle wrapped in a total reflection mirror, driving on the vast photovoltaic panels on the inner surface of the solar crust

One night during the summer vacation, I was lying on the small bed outside the house, looking at the twinkling stars in the sky, and at the white, gushing The Milky Way was resting, and I fell asleep unknowingly...

Suddenly, a luminous round thing appeared in the sky and flew into my house. Ah! It turned out to be a spaceship! Suddenly two guys in special clothes stepped out of the spaceship. Their appearance was very different from ours, but their language could be understood. Are they aliens? I was very surprised. I shouted loudly but no one answered. These two guys pulled me onto the spacecraft roughly. The spacecraft was extremely fast and flew to the moon in a blink of an eye.

When I came to the moon, I was immediately stunned by the sight in front of me: the sky was filled with spaceships, and one of the spacecrafts launched a missile downwards. There was only a roar and a missile appeared on the ground. A large pit hundreds of meters deep. It turned out that they were conducting military exercises.

At this time, an alien came towards me. He told me: "I am the highest commander here. We are doing major military exercises before attacking the earth. We have extremely powerful weapons here. Nuclear weapons, one bomb is enough to destroy your village. Do you know? The village I am talking about refers to a city or country with a population of more than 200 million people. So, we are confident enough to conquer the earth..." He. He left me laughing wildly. I am very worried. I am really afraid that these aliens will destroy our beautiful home.

About a few seconds later, the commander gave an order, and countless spacecraft rushed violently towards the earth. "No, you inhuman things, you can't destroy our home. Mom, mom -" I hated their actions so much that I rebuked and called out loudly...

" Wake up quickly and go to sleep in the house. "My mother shook me awake. It turned out that I had just had a dream.

I think we must study hard, master high technology, and protect our beautiful homeland!
