After two asteroids collided and exploded, Su Zhe's discussion group fell silent.

The members of the discussion group, like Su Zhe, were looking at the data scanned by the three survey telescopes in detail.

Although the collision and explosion were considered before, it really happened to everyone's surprise.

This situation, so to speak, is one of the worst.

Su Zhe read the relevant data of the wreckage and participated in the discussion of the discussion group.

According to known data, the fastest wreckage will hit the Earth on the first day of the new year, which is tomorrow at 6 p.m.

From this point on, the impact of the debris on the earth will last for twelve hours and will not end until six o'clock in the morning on the third day of the new year.

If these wrecks are not intervened and intercepted, human civilization will be destroyed in this wreckage impact.

There is no doubt about this, because twenty-seven wrecks with a diameter of more than one kilometer will hit all continents and oceans, and the landing point of the wreckage with a diameter of thirty-five kilometers is the center of the Americas.

With such a large-scale asteroid debris impact, there will be no chance of survival for mankind.

When Su Zhe and everyone were discussing the interception plan, the code name Zero One announced a piece of news.

All countries in the world, through the United Nations General Assembly, unanimously expressed their support for the use of the Xuanwu defense system to intercept these asteroid wreckage.

The General Assembly urgently passed a bill to support the operation.

Then, Codename Zero-2 posted the target of the interception in the discussion group.

Make sure that the wreckage of the asteroid that falls into the atmosphere is less than five meters in diameter.

Under normal circumstances, an asteroid with a diameter of 10 meters will not affect the surface, but given the composition of the wreckage, it is necessary to control the diameter to less than 5 meters in order to ensure safety.

Once the target is determined, the next step is to develop an interception plan.

After half an hour of discussion, the final plan came out.

Except for the seven-hour blind spot time, and from 10 a.m. to 5 p.m. tomorrow, the SS-Defense system deployed on the ground during this time period will not be able to intercept the wreckage, and it can intercept it at other times.

As for the specific plan, when the wreckage enters the space with the Earth as the center and a radius of 300,000 kilometers, the radius of the wreckage should be less than 5 kilometers.

When entering a space with a radius of 200,000 kilometers, the radius is required to be less than one kilometer.

The radius of the wreckage required for 100,000 km is 500 meters.

The radius of the wreckage required for 50,000 km is 300 meters.

The radius of the wreckage required for 30,000 km is one hundred meters.

The radius of the wreckage required for 10,000 km is fifty meters.

The required radius of the wreckage for five thousand kilometers is thirty meters.

The radius of the wreckage required for three thousand kilometers is ten meters.

The radius of the wreckage required for a thousand kilometers is five meters.

Interception in stages and areas, but considering the blind spot time, some have to be done in advance.

When a group of experts were discussing the specific interception plan, major official media and even the live broadcast of the Spring Festival Gala broadcast an urgent news.

The content is the same, and two asteroids exploded three million kilometers from the earth, and the debris produced by them will threaten the safety of the earth, and then the time Xuanwu defense system will take interception measures, I hope everyone will not panic.

The reason why it was announced was because it couldn't be concealed if you wanted to.

Not long ago, a "sun" glowing white suddenly appeared, and then a red beam of light from the dead light.

These are all things that can be seen, so let everyone guess, it is better to take the initiative to announce it.

No, after the relevant news was announced, the speculation on the Internet about the "sun" that appeared not long ago was instantly revealed.

The creatures who were in a state of terror vanished in an instant.

All earthlings know that the wreckage of the asteroid poses a threat to Earth, and the Xuanwu defense system is about to intercept it.

When there was a lot of noise on the Internet at home and abroad, the specific interception plan came out.

Only a quarter of an hour passed after the plan came out.

That is, ten in the night

At 50 o'clock, countless red beams of different thicknesses appeared all over the country and shot into space.

……

After the specific scheme of interception was determined, the SS-defense system began to act.

According to the scheme, the first thing the SS-defense system had to deal with was a wreckage with a diameter of more than five kilometers, and there were four such wreckage.

There are three from 5 km to 10 km.

The largest remaining wreck is thirty-five kilometers in diameter.

The SS-Defense system was the first to attack the largest wreckage, with a diameter of up to 35 kilometers.

Su Zhe glanced at all the subsystems of the SS-Defense System and saw that most of the Death Light was preparing.

I took a closer look at the methods of dealing with this wreckage with a diameter of thirty-five kilometers.

One-third of the domestic Deadlight is activated, including three sets of Premium-Deadlight.

Concentrate the launch, and be sure to disintegrate this massive wreckage with a single blow.

The same method will then be used to deal with the three wrecks between five and ten kilometers.

Seeing that the preparations were almost ready, Su Zhe came to his parents' room with his laptop.

Grandpa and little sister were left in the room.

After asking, I found out that his parents were talking about this with others outside the door because of the "sun" that suddenly appeared before.

Seeing Su Zhe holding his laptop, Su Daniu asked, "What did the host of the Spring Festival Gala say about asteroids and wreckage before, and said that there was a Xuanwu defense system to intercept it, what is going on?"

"It's just two asteroids colliding ......," Su Zhe explained simply.

Su Zhe also called up the picture of the collision of the two asteroids to show his grandfather and little sister, and said that the Xuanwu defense system was about to start intercepting, and the red beam produced by the interception was much better than fireworks.

Hearing Su Zhe say this, the little sister Su Meiyun hurriedly jumped off the chair.

The Spring Festival Gala was not interested in watching it, so he took his eldest brother Su Zhe and grandfather Su Daniu to look outside the house.

Su Zhe held a laptop in one hand and his little sister Su Meiyun in the other, and came to the open ground in front of the gate with his grandfather Su Daniu.

At this time, Su Zhe's parents were chatting with their neighbor's uncle and uncle not far away, about the "sun" that suddenly appeared before and the news of the interception of the asteroid wreckage announced by the relevant media.

And in the distance, fireworks explode from time to time.

Su Zhe didn't call his parents, but went into the house and moved a small square table and three chairs.

He placed his laptop on a small square table and sat in front of it, while his grandfather and little sister sat next to him.

The trio stared at their laptops.

Su Zhe took a look, and the ground-related SS-defense system subsystem base was ready.

There were three minutes left before the time of the attack.

The laptop screen rotated, and there were three official probes deployed in space, and three probes with a first-level death light.

The first-level death light carried on it simultaneously emitted a red beam.

In just ten seconds, the three first-stage dead lights carried by the three probes fired twelve red beams without interruption.

Su Zhe knew that the purpose of these red beams was not to attack the wreckage of an asteroid with a diameter of thirty-five kilometers, but to determine the accuracy of the predictions of the SS-Defense System.

Its purpose is the accuracy of the positioning of the SS-defense system.

Next to Su Zhe, his grandfather and little sister stared at each other, and the two couldn't understand it at all.

Su Da Niu was a little shocked, and asked in disbelief, "Sun ...... Xiao Zhe! Are you involved in the Xuanwu Defense System?"

"Yes! There is participation!" Su Zhe nodded affirmatively, "Grandpa! Younger sister! The interception will begin immediately, and you will watch the sky."

When Su Zhe spoke, the attack had already entered the countdown, and he raised his head and shouted after him.

「…… 5、4、3、2、1。」

As soon as Su Zhe's words fell, countless red beams of different thicknesses flashed in the sky.

Immediately afterward, a large fireball appeared in the far reaches of the sky.

The big fireball only lasted a few seconds

Gone.

At this moment, the fireworks in the distance dimmed.

"Beautiful! It's so pretty!" Su Meiyun shouted.

"This ...... That's the power of the Xuanwu Defense System." Su Da Niu exclaimed.

Su Zhe heard the exclamations of his parents and neighbors' uncles not far away.

He smiled and began to see the effect of the blow.

From the real-time monitoring footage of the three survey telescopes, it is known that the wreckage of the asteroid with a diameter of 35 kilometers was hit by numerous red beams at a distance of 2.73 million kilometers from the earth.

An explosion ensued.

According to the scanning results of the three survey telescopes, the effect of this blow is still good.

The explosion of the wreckage of this asteroid with a diameter of 35 kilometers produced the destruction of an asteroid with a diameter of 11 kilometers.

Five kilometers to ten kilometers are not.

There are only three from one kilometer to five kilometers.

Among the remaining mutilations, there are also some that are five meters to one kilometer, but many more are less than five meters.

He carefully analyzed the process of the attack, which was very different from the design of the attack.

According to the design, after this wave of attacks, the diameter of its wreckage will be less than five kilometers.

But the result was a wreckage with a diameter of eleven kilometers.

As for the occurrence of such a situation, there are two reasons, the material composition inside the wreckage is not understood, the distance is too far, and there is a slight deviation in the attack point of its beam.

Think about it, such a lapse is within acceptable limits.

At this moment, the discussion group was unusually lively, and everyone was saying their opinions.

The results of everyone's analysis were similar to Su Zhe's.

Just when Su Zhe was holding his mobile phone to watch the speeches of the discussion group, he heard the little sister Su Meiyun ask, "Big brother! Is there anything else to look at?"

Su Zhe turned his head and said with a smile, "And!"

As he spoke, he looked at the laptop, and the targets of the second wave were four.

One wreck with a diameter of eleven kilometers plus three wrecks from five kilometers to ten kilometers.

He looked at the countdown and shouted.

At this time, his grandfather, little sister, and his parents not far away all looked up at the sky.

After Su Zhe finished shouting, countless red beams of light appeared in the sky again.

Then, four small fireballs appeared in the sky.

Four small fireballs lasted a few seconds.

"Big brother! Eldest brother! Anything else? Anything else?" Su Meiyun shouted.

"Also, but it's going to take a long time, and it's not as good as these two times." Su Zhe explained, "Wait for tomorrow, tomorrow I can watch the meteor shower overnight."

"Really? I can watch meteor showers all night." Su Meiyun asked happily.

At this time, Su Zhe's parents and those uncles and uncles came over.

Su Zhe hurriedly hid the SS-defense system picture.

"What! Can you watch a meteor shower overnight tomorrow?" Su Jianguo asked curiously.

Those uncles and uncles also looked at Su Zhe curiously.

Su Zhe smiled and said, "Yes! On the first night of the new year, there will be a continuous stream of meteor showers."

Those uncles didn't understand and didn't believe it.

Su Zhe saw that these people didn't know much about this incident, and planned to talk to everyone.

Just as I was about to start talking, all the adults and children in the neighborhood came running.

Su Zhe's parents enthusiastically brought the stool and took melon seeds and candy.

After everyone was done, Su Zhe began to speak.

He said in a way that everyone could understand that two asteroids collided three million kilometers from Earth......

After talking for a long time, those children understood, but those adults did not.

When I asked, I found out that many of these uncles and uncles didn't even know that the earth was round, and some didn't even know what the earth was.

I don't even know the most basic cosmology, and it's too hard for these uncles and uncles to understand.

He didn't think that way either.

In the end, it was his grandfather Su Da Niu who stood up and said, "You adults don't understand and go home and let your children teach you, now you just need to know that there will be a continuous meteor shower tomorrow, that is, on the night of the first day of the new year."

As soon as Su Daniu's words fell, these uncles and uncles shouted.

It's better to read books, know astronomy and geography, and say that in the future, you must let the children in the family take the university entrance examination and learn Su Zhe.

Everyone chatted for a while, and someone shouted that it was almost twelve o'clock at night, saying that they would go home and set off fireworks.

Su Zhe's family is the same, after everyone left, Su Zhe and his father Su Jianguo moved out many fireworks and 10,000 firecrackers and put them up.

Just past midnight, Su Zhe held Su Meiyun and lit 10,000 firecrackers.

For a while, the sound of firecrackers in the distance and near sounded at the same time.

At the same time as the 10,000 firecrackers burned out, the general fuse of those fireworks was lit.

The total leads burned all the way, and the fireworks were lit one after the other.

Immediately, the fireworks continued to rush into the sky.

After watching their own fireworks, the family watched other people's fireworks for a while.

Su Zhe helped his grandfather Su Da Niu back to sleep.

On the way, Su Daniu was a little excited and asked a lot of questions about the Xuanwu defense system.

Su Zhe didn't hide it, and picked up what his grandfather understood.

"Good! Contributing to the country is what you should do." Su Da Niu said excitedly, "Right now, with the Xuanwu Defense System, it's good that we don't bully others, we can be regarded as truly standing up."

"Yes! I'll continue." Su Zhe smiled and nodded.

"Yes! That's right, there is no country and there is a home!" Su Da Niu thought for a while and asked, "Xiao Zhe! You and I have a good talk about the universe and the solar system, and I didn't understand it before."

Su Zhe and his grandfather explained what the universe is, what the solar system is, and how the moon revolves around the earth.

In the end, he talked about the development and construction of the school in the Tamu Gobi, the super factory, the three-door project, the light pillar project, and the development of the solar system.

Although Su Daniu didn't understand it too well, he finally understood the development of the solar system.

"Xiao Zhe! This...... Are you involved in all of this?" Su Daniu asked in surprise.

Su Zhe nodded affirmatively and said, "Everyone is involved!"

"Good! Worthy of my eldest grandson!" Su Da Niu smiled and asked, "Xiao Zhe! It's time to develop the solar system, do you think I can go to the moon at my age? I want to see if there are Chang'e, Wu Gang, and Moon Rabbits on the moon."

"Yes!" Su Zhe said with certainty.

"Boy! You can't fool your grandfather!"

"No one can fool grandpa! I will definitely take my grandfather to the moon to see Chang'e!"

"Good!"
