Su Zhe hugged his little sister Su Meiyun, listening to his grandfather Su Daniu talk about the universe and the solar system, while watching the live broadcast of the National Space Station's return to the spacecraft.

The more his grandfather Su Da Niu spoke, the more excited he became, and there was no rhythm to stop at all, and the live broadcast of returning to the spaceship came to an end.

The three astronauts had already left in a medical vehicle.

But the live broadcast didn't end there.

The live stream screen changed from returning to the ship to the studio.

The studio has a female presenter and two experts, and the background is a starry sky.

Countless "stones" flew quickly across the starry sky.

The moderator and two experts began to detail the beginning and end of the crisis.

It starts with the first probe hitting an asteroid......

On the morning of the first day of the new year, Su Zhe watched the live broadcast and listened to everyone's discussions.

After lunch, Su Zhe squinted for a while.

At three o'clock in the afternoon, he sat down in front of his laptop and carefully watched the results and preparations of the SS-Defense system.

In the afternoon, he didn't plan to go out and hang out, but stayed in front of his laptop and watched the SS-Defense system in action.

At present, the asteroid wreckage is in the blind spot area intercepted by the SS-defense system, and the asteroid wreckage will not appear in the interception and strike area of the SS-defense system until 5 o'clock in the afternoon.

At this moment, the vanguard of asteroid wreckage, that is, the first wave of asteroid wreckage, has flown through the lunar orbit, less than 100,000 kilometers from the Earth.

This first wave of asteroid debris was created after the two disintegration of the largest asteroid debris with a diameter of 35 kilometers after the collision of two asteroids.

Most of the impact sites of the first wave of asteroid debris were in the Americas.

This first wave will last for a quarter of an hour.

A quarter of an hour after the end of the first wave, a second wave of asteroid debris hit.

The impact sites of the second wave of asteroid debris are basically in the European region.

The duration of this wave is half an hour.

Whether it is the first wave or the second wave, the largest of these asteroid debris is only five meters in diameter.

Normally, these asteroid wreckage burn up in the atmosphere.

However, there are exceptions, such as asteroid damage that contains metals that are not easily burned, or other substances, which are also possible.

These materials that are not burned will be smashed to the ground, but the volume of these materials that are smashed to the ground will not be too large, and the relative threat is not large.

Compared with previous meteor showers, the meteor showers formed by the impact of these two waves of asteroid debris will be very spectacular.

Not only will the overall duration last, but there will be many "large meteors", a single meteor will last for a long time, and it will also produce the sound of an air explosion.

Especially for asteroid debris with a diameter of nearly five meters, the asteroid debris of this size will burn up at a much lower altitude.

Su Zhe didn't have the eyes to see these two waves of meteor showers, but the people of the Americas and Europe were able to feel it in advance.

The most important thing is that when the first wave of meteor showers began, the American continent was in the dark night, and when the second wave of meteor showers began, the sky on the European continent was only cloudy, which did not affect the viewing of meteor showers.

After the two waves are over, a large force of asteroid wreckage will appear at six o'clock in Yanjing time.

A large force of asteroid debris will first hit the Pacific region and then envelop the entire Earth.

The time will last for twelve hours.

Su Zhe tracked the first wave of asteroid wreckage in real time through the SS-Defense system.

At the same time, it was found that the trajectories of most of the satellites and probes over the Americas had been adjusted.

Compared to avoiding the asteroid debris that is coming.

He looked at the time, and it was thirty-fifty-five.

Just after reading the time, a moon at an altitude of 9,000 kilometers above the Atlantic Ocean was smashed into slag by the wreckage of an asteroid with a diameter of two meters.

This satellite was really unlucky, it was obviously in high orbit, but it was still hit by the wreckage of an asteroid.

he

It is guessed that this satellite should have lost the ability to maneuver.

You know, the trajectories of these asteroid wrecks have been shared, and it is common sense that this will not happen.

As the first wave of asteroid debris gets closer and closer to Earth, satellites in high and low orbits, probes have basically avoided those asteroid debris.

Now it's time to avoid it, and then it's up to you to see if you have more fuel and luck.

Just when Su Zhe sighed, the time came to five o'clock.

Thousands of asteroid debris crashed into the atmosphere of the Americas region.

Countless bright lights fell to the ground.

Su Zhe saw this scene from a space perspective through the SS-defense system.

He knew that from space it was certainly not as shocking as it was from the ground.

The process lasted a quarter of an hour before it ended.

After reading this, he immediately switched to the second wave of asteroid wreckage.

The head of this wave of asteroid debris crossed the synchronous orbit and flew towards the Earth at a rapid pace.

The time came to half-past four.

Like the first wave of asteroid debris, these asteroid debris rushed into the atmosphere at a very high speed.

Every wreck burned and streaked through.

……

People in the Americas and Europe learned about the time of the asteroid wreckage through the Internet or other means, and they stood outdoors, many people took out professional shooting tools to record this moment, and there were not a few people who broadcast live.

Before the first wave of asteroids hit, the American continent was shrouded in darkness.

People in the dark look at the time displayed on their phones and look up at the sky.

In the darkness, the stars in the sky are particularly conspicuous.

Suddenly, a bright light flashed in the sky.

Then, more and more light fell, and its density exceeded that of all previous meteor showers.

For a time, the people of the American continent were excited, praising the beauty and grandeur of the meteor shower.

More than ten seconds passed, and a continuous roar reached the ground, and the sound was like a mixture of sonic boom and thunder.

In addition, a lot of light keeps falling, and it disappears at very low altitudes.

At this moment, many people felt fear.

This process lasted a quarter of an hour.

It was only after the end of the day that the people of the American continent woke up from their fears and knew that there was no real threat from these asteroid wreckage.

At this moment, it is not only the people of the Americas who are afraid, but also the people of the world who are watching the live broadcast.

The first wave of asteroid wreckage is over, and the world's attention has shifted to Europe.

At this moment, the European continent is clouded, and in the "anticipation" of the people of Europe and the world, the impact of the asteroid wreckage has begun.

The dense falling lights and roars overwhelmed the Europeans.

It was only after the sun rose above the horizon that the falling lights and roars ended.

At this time, Yanjing time is five o'clock in the afternoon.

Su Zhe looked, and the SS-defense system began to intercept.

At first, there weren't a lot of red beams emitted, but as time went on, more and more red beams flashed through the sky.

Su Zhe stood by the window and looked at it, thinking it was not interesting, and sat back in front of the laptop.

Just about to watch the first and second waves of ground shooting videos, his little sister Su Meiyun staggered to the room.

"Big brother! Eldest brother! It's time to eat!"

"Good! Eat!" Su Zhe got up and picked up his little sister.

The family ate very quickly, and it took less than half an hour to finish dinner.

At 5:50, the dishes and chopsticks were all put away.

Su Zhe and his father moved the Eight Immortals Table to the open ground in front of the door, and the family sat at the Eight Immortals Table.

By this time, it was already dark, and some shining stars could be faintly seen.

"Xiao Zhe! The meteor shower starts at six o'clock, right?"

Su Jianguo asked.

"Yes!" Su Zhe replied while watching the second wave of videos shot on the ground.

Su Daniu looked at the laptop screen and said, "This meteor shower is so scary, it's like a bombing."

Su Zhe nodded and reminded, "Don't worry about what you see or hear for a while, nothing will fall to the ground."

At home, unlike abroad, if there is an asteroid with a diameter of five meters that is not completely burned up, the SS-defense system will continue to strike at the wreckage.

There will be no debris falling to the ground.

"Good!"

"Got it!"

His parents and grandfather nodded and said.

Su Meiyun looked at the sky and shouted, "There are so many red lights!"

In an extremely short period of time, countless red beams flashed, and multiple small fireballs appeared in the far reaches of the sky.

Su Zhe saw the family looking at him, and he explained, "These red beams are hitting the debris of an asteroid with a huge volume."

The red beams shouted by the little sister Su Meiyun hit the asteroid wreckage with a diameter of one kilometer to five kilometers.

For the next period of time, the SS-Defense system will continue to output a large number of red beams to strike the asteroid wreckage, so that the asteroid wreckage will eventually be less than five meters in diameter.

At the same time, it is necessary to destroy the debris of the asteroid that threatens the two space stations, space solar power stations, satellites, probes, etc.

But satellites and probes that aren't their own won't care.

"Huh!" Su Meiyun nodded seriously, "Big brother! When does the meteor shower start?"

"A few minutes!" Su Zhe smiled and said, "Let's look east."

"Which direction is east?" Su Meiyun asked in a milky voice.

"The direction in which the sun rises." Su Zhe replied with a smile.

"Huh! Got it!" Su Meiyun nodded.

When the family looked to the east, the time came to six o'clock.

In the distant sky in the east, a bright light fell directly below the horizon, and then countless bright lights followed.

"Big brother! This is a meteor shower! Pretty, so pretty!" Su Meiyun shouted.

Su Zhe hugged the little sister standing on the stool in his arms and said, "Little sister! After a while, the voice is a little loud, there is a big brother, don't be afraid."

"Yes! I won't be afraid!" Su Meiyun nodded affirmatively.

Su Zhe smiled and looked up at the sky, and the falling light came from far and near.

In a few moments, a falling light lit up the sky, accompanied by a piercing roar.

Looking at the bright light falling from the sky and listening to the piercing roar, Su Zhe felt the ultimate sense of oppression.

It gave him the impression that countless fireballs were constantly falling to the ground.

Relieved of the oppressive feeling are the red beams that keep flashing.

He couldn't help but sigh that if there was no Xuanwu plan, or if there was no implementation of the Xuanwu plan at all costs, the future of mankind would be buried in this disaster.

There are twenty-three asteroid wrecks of one kilometer to five kilometers, and three asteroid debris of five kilometers to ten kilometers.

There is also an asteroid wreck with a diameter of thirty-five kilometers.

The Earth is able to withstand the impact of these asteroid debris, but humans on Earth cannot.

Looking back, he himself was a little afraid.

In the face of these catastrophes, humanity is too small.

Fortunately, in the shortest possible time, the SS-defense system was fully deployed.

In fact, after the collision and explosion of two asteroids, he was very worried, worried that the asteroid contained a large amount of radioactive material.

If there is a large amount of radioactive material in the asteroid damage, even if the SS-defense system is deployed, human civilization will not be able to escape the result of destruction.

This time, human luck is good, after close detection, the remains of these asteroids have only a very small amount of radioactive material, which will not affect the existing ecological circle of the earth.

If the debris contains a large amount of radioactive material, even if the debris burns up in the atmosphere, the burned residue will still float in the atmosphere, and eventually the radioactive residue will settle to the ground.

The consequences can be imagined......

Just as he was thinking about it, he understood his mother Yang Xiuzhi tremblingly muttering, "This...... What if these lights hit the ground!"

Su Zhe looked at the little sister in his arms and found that the little sister Su Meiyun looked at the sky with a curious face, without a trace of fear.

Su Jianguo turned his head to look at Su Zhe, and said with some fear, "Xiao Zhe! Are these meteors really not going to fall to the ground?"

"Nationhood! What do you have to worry about?" Su Da Niu said indifferently, "Xiao Zhe said that he wouldn't fall if he didn't fall."

Su Jianguo nodded.

Su Daniu said with some excitement: "I think that when we were fighting, the cannons and aerial bombs kept exploding, and we were not afraid."

"Dad! There is no comparison between fighting and fighting." Su Jianguo pointed to the sky and said, "If these meteors fall to the ground, they will be much more powerful than those aerial bombs and missiles, and I heard that the dinosaurs were killed by these meteors."

"Why can't it be compared!" Su Da Niu said, "You haven't been on the battlefield, do you know what the battlefield is like?"

"I haven't been on the battlefield, but I've seen it on TV." Su Jianguo replied.

"You can take it seriously when you watch it on TV!" Su Da Niu was a little disdainful.

……

While Su Zhe's father and grandfather were debating, most of the world was hit by large-scale asteroid wreckage.

In the dark night area, people watch the falling meteors and listen to the piercing roar, some are afraid, some are excited......

In the daytime area, people could not see the obvious light falling, only the roaring sounds, which made people uneasy.

At this moment, everyone on earth knows that humanity is on the verge of destruction.

If it weren't for the emergence of the Xuanwu defense system, humanity would have been ironclad in this catastrophe.

Meantime! People have seen the power of the Xuanwu defense system, which can disintegrate the asteroid wreckage more than two million kilometers away with a single blow.

And it can hit so many targets at the same time.

Such a powerful Xuanwu defense system is daunting!
