On the morning of the thirtieth day of the Chinese New Year's Eve, Su Zhe was called up early by his little sister Su Meiyun.

After breakfast, Su Zhe took Su Meiyun and Yang Weiwei to the town to go shopping.

said it was shopping, but in fact, he accompanied his little sister to the street to see the excitement.

There are spring couplets, lanterns, fireworks, toys, dried fruits and fruits sold on the street.

Su Zhe and Yang Weiwei like the atmosphere of the New Year, while Su Meiyun likes to play monkeys.

This is also the main purpose of Su Zhe taking Su Meiyun to the street.

The three of them watched the monkey all morning, and it didn't end until Su Zhe's mother called home for lunch.

After lunch, Yang Weiwei went home, and Su Zhe sat in front of the laptop with his little sister Su Meiyun in his arms.

The two are with Ning Qiaoqiao.

, Ning Qiaoqiao is making dumplings with her father Ning Changsheng.

In the process of opening, it was basically Su Meiyun and Ning Qiaoqiao chatting, and Su Zhe and Ning Changsheng were just backgrounds.

Su Zhe was also very puzzled, I don't know why the little sister Su Meiyun chatted so happily with Ning Qiaoqiao.

The two of them are like little sisters.

After the end, Su Zhe used his computer to log in to the SS-defense system.

The first thing he looked at was the deployment of the SS-defense system.

Just when he was about to take a closer look, he heard his little sister Su Meiyun say, "Big brother! You let me down, I'm going to see Mommy's croquettes."

"Good! I'll send you there." Su Zhe stood up with his little sister in his arms.

When he came to the kitchen, Su Zhe put his little sister Su Meiyun on the ground, and Su Meiyun shouted that her grandfather ran directly to her grandfather Su Da Niu, who was burning the fire under the stove.

Su Zhe left the kitchen with a freshly fried balls from his mother.

When he passed by the hall, he was stopped by his father Su Jianguo and asked him to help paste the Spring Festival couplets.

Every year, he and his father posted the Spring Festival couplets together, and it has long been a routine.

Su Zhe and his father chatted while pasting Spring Festival couplets.

The content of the conversation is nothing more than asking Su Zhe to work hard, saying that when he becomes a teacher, he must be responsible for his students, and he must be like Teacher Fan Xiaohui.

Su Zhe nodded the whole way.

After pasting the Spring Festival couplets, Su Zhe returned to the room and sat in front of his laptop to watch the deployment of the SS-defense system.

All 3,000 SS-defense system subsystems in China are online, which means that 3,000 SS-defense system subsystems have been deployed.

In space, not only were thirty temporary probes deployed, but three serious probes were launched during the time that followed.

Each of the three probes has 22 tons, which not only has more powerful detection capabilities, but also carries a first-stage dead light emitter.

To date, the SS-Defense System has completed three thousand SS-Defense Subsystem subsystem bases on the ground, thirty temporary probes and three full-fledged probes in space, plus three supernumerary survey telescopes.

The scope of its effective exploration and effective interception is space with the earth as the center and a radius of 300,000 kilometers.

Counting the three survey telescopes, the local ones can see farther.

After watching the deployment of the SS-defense system, the real-time monitoring data of the two asteroids that are about to collide is called up through the SS-defense system.

It is now highly certain that two asteroids, one 10 kilometres in diameter and one 150 kilometres in diameter, will collide at a distance of 300 kilometres from the Earth at 9:10:45 tonight. ….

After reading this, Fan Xiaoming sent a request.

At this time, Fan Xiaoming was at home in Shangling City, and his object was still sitting next to Fan Xiaoming.

After the three of them finished talking about Happy New Year, they then talked about the collision of two asteroids.

Just like Fan Xiaoming said, if two asteroids collide and there is no threat to the earth, it is fine, once there is a threat, I believe many people will not be able to sleep today.

While the three of them were chatting, all three of them received an email with the same content, joining a temporary discussion group.

The group was dealing with two asteroids that were going to collide tonight.

After Su Zhe joined, he found that the individual's name was not displayed in the discussion group, only the code name.

The largest code name for a discussion group is one thousand and one, which means that there are one thousand and one members of the discussion group.

Su Zhe's code name is zero three, Fan Xiaoming's code name is one zero, and Fan Xiaoming's object code name is eight seven seven.

The three of them chatted for a few words and it was over.

At this time, the discussion group was lively.

At first, everyone was in the discussion group talking about two asteroids that were about to collide.

But chatting and chatting, the person codenamed Zero Four sent a photo, a photo of making dumplings.

The direction of the discussion group changed immediately.

Everyone began to post photos, and the photos were not dumplings, various dishes, or Spring Festival couplets or something.

After that, everyone talked about the customs of the New Year in various places.

When Su Zhe saw the first photo he posted, he knew that the codename Zero Four was either Professor Ning Changsheng or Ning Qiaoqiao.

I called to confirm that this zero four was really Professor Ning Changsheng Ning.

According to Professor Ning Changsheng Ning, there is no need to discuss these things so seriously for the New Year, anyway, everything that should be prepared has been prepared, and there is no point in discussing it now, it is better for everyone to discuss the New Year.

In this regard, Su Zhe agreed, after all, the result can only be known after the collision of two asteroids.

Ending the call, Su Zhe found that Zero Four had been speaking in the discussion group to liven up the atmosphere.

He guessed that the responsible persons of the relevant departments organized by the discussion group probably dared to be angry and did not dare to speak out, after all, Professor Ning's status was there.

In addition, the discussion group is basically composed of experts in related fields, and the responsible persons of relevant departments can only turn a blind eye.

In the discussion group, when everyone was posting photos and discussing the New Year, the codenames Zero One and Zero Two tried to pull the topic back.

But just when there was a little effect, Zero Four came out again with rhythm.

Eventually, Zero One and Zero Two also gave up their resistance and joined the ranks of posting photos and chatting.

As soon as it got dark, the sound of firecrackers began one after another.

At about six o'clock in the evening, Su Zhe lit a string of 3,000 firecrackers and quickly ran into the hall.

In the sound of firecrackers and the shouts of the little sister Su Meiyun, the Chinese New Year's Eve dinner began.

Su Daniu took out two red envelopes, and Su Zhe and Su Meiyun happily took the red envelopes given by their grandfather.

The family gathered around the table for a hot Chinese New Year's Eve dinner.

When Su Zhe was toasting his grandfather Su Da Niu, Su Da Niu asked with a smile, "Xiao Zhe! I heard my comrades-in-arms say that after we have some Xuanwu defense system, we will not be afraid of the great powers and imperialism, and we can press them down and fight them, is this true?" ….

"Grandpa! It's true! It's all true!" Su Zhe nodded affirmatively.

"Good! Very good!" Su Daniu smiled and drank the liquor in the cup.

After eating the Chinese New Year's Eve dinner, Su Zhe helped his parents clean up the dishes and chopsticks, and then set off fireworks.

This year, because I was not short of money, I bought a lot of fireworks.

Su Zhe and his father Su Jianguo were busy for half an hour before they made a fireworks array in front of the door.

Not only do you have to connect all the leads, but you also have to take safety measures.

After confirming the safety, Su Zhe held Su Meiyun and lit the general lead with a lit incense.

After lit, Su Zhe ran to the door quickly with his little sister in his arms.

Set up for half an hour for five minutes.

In these five minutes, the other fireworks have become the accompanying village, which is the most exciting.

After the fireworks ended, the family sat in front of the TV to watch the Spring Festival Gala.

Su Zhe found that his grandfather, parents, and little sister all like to watch the Spring Festival Gala, especially his little sister Su Meiyun, who couldn't stop laughing when she watched it.

At this moment, Su Zhe's mother Yang Xiuzhi's mobile phone rang, and it was sent by Ning Qiaoqiao.

Su Zhe found that his mother, little sister and Ning Qiaoqiao were chatting very happily.

Looking at this situation, Ning Qiaoqiao is very familiar with his mother.

Ending the call, Yang Xiuzhi looked at Su Zhe and said, "Qiaoqiao is good! you

Use more snacks!"

"What heart?" Su Zhe was a little puzzled.

"Big brother! Let Sister Qiaoqiao be my sister-in-law!" Su Meiyun reminded.

"Tell me about you, you're not as good as your little sister!" Su Jianguo said next to him.

"Everyone Qiaoqiao knows to greet us, why don't you start greeting Qiaoqiao's father, Professor Ning." Yang Xiuzhi said with a smile.

"Ah! This...... Got it!" Su Zhe said as he stood up and walked towards his room.

In the past, he really didn't think about it.

Looking back, it would be nice to be able to be with Ning Qiaoqiao, after all, the two have a common language.

It's also very comfortable when you're together.

Coming to the room, Su Zhe sent a request to Professor Ning Changsheng Ning.

seconds on.

The two chatted about some homely things.

Su Zhe took the initiative to ask some topics about Ning Qiaoqiao's life.

The conversation ended at 8:50 a.m., when the two received reminder emails at the same time.

While Su Zhe landed on the SS-Defense system, he was also browsing the content of the discussion group.

The issue discussed was the problem of the dead end of the interception of the SS-defense system.

Although the SS-Defense system can explore every direction of the earth without blind spots, it cannot intercept flying objects in every direction, and there are blind spots.

In fact, it is possible to intervene in advance for distant targets, but it is a bit troublesome.

It is said that it is discussing the problem of intercepting dead ends, but in fact, it is discussing the issue of cost.

According to the plan given by the relevant departments, the wreckage of the two asteroids that collided will be intercepted and destroyed in China, and in principle, it will not matter in foreign countries, but the super-large wreckage will intervene in advance.

Then there are the requests from other countries to intervene.

There's a cost to doing that, so now you're calculating the cost.

The cost of asteroids of different sizes and directions is different.

Soon, the costs were all calculated.

In the case of multiplying the cost by ten times to a hundred times, the relevant departments sent the relevant quotations to the relevant foreign institutions and organizations. ….

At nine o'clock in the evening, that is, more than ten minutes before the collision of the two asteroids, the relevant agencies of foreign countries received this offer.

The offer is public, but different countries will treat it differently.

After receiving this offer, these institutions and organizations reacted differently, some asked for help, some refused, some ridiculed, and some did nothing.

At this moment, the two asteroids that are about to collide are being monitored conditionally.

What these people hope most is that the debris after the asteroid collision will have no impact on the Earth at all.

Otherwise, they will bleed profusely.

They all knew that it was better to bleed than to crash the wreckage into the land.

A smaller wreck is fine, but if the wreckage is a little bigger, the result will be disastrous.

It's better to spend some money.

……

Su Zhe knew that the SS-defense system had been fully prepared, after all, the drill was based on the worst-case scenario.

Minute by minute.

The time came to ten o'clock in the evening, and Su Zhe stared at the laptop screen.

Its heart was beating fast.

Soon, an asteroid with a diameter of 10 kilometers and an asteroid with a diameter of 150 kilometers will collide.

The unsettling mystery is finally about to be revealed.

Is the wreckage completely harmless to Earth, or the worst-case scenario, or ......

When the relevant probes from all over the world were looking at this space 3 million kilometers from the earth, Yanjing time came to 9:10:45 p.m.

Somewhere three million kilometers from Earth, an asteroid with a diameter of 10 kilometers collided with an asteroid with a diameter of 150 kilometers.

An asteroid with a diameter of 10 kilometers directly crashed into an asteroid with a diameter of 150 kilometers

Interior.

Just when the watchers were confused, a shining white pass flashed.

"Not good!" Su Zhe shouted as he looked at the white computer screen.

At the same time, the window lit up.

Su Zhe came to the window and found that the night had turned into day, and a "sun" glowing with white light appeared in the sky.

Seeing this, he began to worry.

Fortunately, this white light only lasted for a few seconds.

He returned to his computer, glad that the SS-Defense system and the three survey telescopes were still working.

At this very moment, three telescopes are scanning the space where the explosion occurred.

Yes! Two asteroids collided and exploded.

With constant scanning, the data displayed on the computer screen is constantly updated.

In fact, you don't need to look at these data to know that the situation after the explosion is not optimistic, and there will be no fewer wreckage flying to the earth.

A quarter of an hour passed, and the wreckage with a diameter of more than a hundred meters was basically recovered.

Among them, there are three hundred wrecks that pose a threat to the earth.

There are 183 from 100 meters to 500 meters, 90 from 500 meters to 1 kilometer, and 27 from more than 1 kilometer.

Of the twenty-seven that exceeded one kilometer, twenty-three were from one kilometer to five kilometers, and three were from five kilometers to ten kilometers.

The last remaining wreckage is thirty-five kilometers in diameter.

Another quarter of an hour passed, and the wreckage with a diameter of ten to one hundred meters was also found.

Among them, the number of harmful to the earth has reached more than 100,000.

As for the wreckage with a diameter of less than ten meters, it is not being detected, and there is no need to detect it.

Three survey telescopes are constantly updating the data of the wreckage, and all the collected data is sent into the simulator.

Half an hour later, the trajectory of the debris with a diameter of more than 10 meters and the location of the debris on the earth were all released.

At this time, countries with observation capabilities and their relevant institutions and organizations called one after another, clearly saying that they would jointly face this catastrophe for mankind.

Soon, the United Nations General Assembly issued a joint statement that those who have money will contribute their money, and those who have resources will contribute their resources, and mankind must unite to face the disaster together.

Seeing that the relevant countries had expressed their positions, the relevant domestic departments responded quickly and sent the relevant data of the detected debris that posed a threat to the earth to the relevant departments of the United Nations General Assembly.
