The puppy likes to rummage through the trash can, and this is a habit that he first discovered on the third day. Because it is no longer hungry and has the strength to run around, the park's trash cans have become its most frequented spots. Although it usually finds nothing, sometimes it will dig out some food or find some small things to bring back to its cardboard box.

No one is ready to adopt it these days, and it has made the cardboard box at the entrance of this park its home. It also began to become messy like an ordinary stray dog, and its originally smooth and beautiful hair was gray and black, making it even more difficult for it to be adopted.

But at first, she didn't care about that, because in some sense, she herself was filthy.

Unlike the puppy, Chu sits there all the time, she is like a plant in this park, usually does not move, only occasionally does it move.

Three days have passed, and the people who pass by the park seem to have gotten used to the two stray maidens and puppies. One or two well-meaning people left some food, but at first she didn't eat anything more, and she fed it all to the puppy, and she couldn't keep feeding it with sin.

In the afternoon of this day, Chu still sat next to the cardboard box, kept silent, and looked at the city in the distance. If it weren't for the occasional blink of an eye, someone might have thought she was a sculpture.

The puppy had something in its mouth and ran from a distance on its somewhat thin legs.

It ran up to Hatsu and put down the contents of its mouth.

"Wang. It barked at Hatsu and spun in circles.

Chu was attracted to it, lowered his eyes, and looked at what it had brought back. Today it has brought back a lot of garbage, all in cardboard boxes.

What was placed on the ground was a broken toy, why it was broken, because it was missing an arm. But if it weren't, it shouldn't have been thrown away.

There's something special about this toy, at least at first glance. It looked a lot like a friend she had known from the past.

It is a broken robot, the paint on its body is painted with rust, and it is definitely not the type that children like in appearance, it is neither good-looking nor handsome, and even a little rough.

Hatsu picked it up and looked at it carefully in front of him.

She found a button on the robot's back and pressed it with her finger.

"Didi. The robot toy's eyes flickered a few times, and he said in a non-obvious electronic voice.

"Defend the planet. ”

The corners of Chu's mouth were slightly hooked, it was really like, and the friend she remembered.

That robot, is it still watching over the gray-green planet, and the humans it is looking forward to must have returned.

Chu pressed the button on the back of the toy again, the pale green light flashed in the toy's eyes, and the electronic voice repeated the phrase to defend the earth.

When the puppy saw Chu smiled, he barked twice excitedly, and wagged his tail and lay on the ground.

In the quiet park, two beings who don't know where they are going are entertaining themselves, their joy seems incomprehensible to others, but it is so simple.

It was getting late, and Chu put the broken toy robot by her side, which was the gift she got on the third day.

The puppy ran back into the cardboard box and played with the ball he picked up today.

The evening sun had dyed the streets of the city crimson, and when she looked at the sky, she was stunned.

Chu's eyesight was several times that of ordinary people, so she could see things that ordinary people couldn't see, and she saw a black dot moving slowly in the sky.

At the same time, on the screens of several buildings in Central, the live broadcast of the planetarium requested by the mayor was also recording this moment, and the black dots were slowly expanding.

Under the screen of the building, the city was as busy as ever, with people coming and going, but no one noticed the change in the black dot on the screen.

Some people will glance at it and leave with a smile, still expecting the so-called spectacle to come a few days later.

······

The Central City Astronomical Monitoring Station, during this period of time, the monitoring station is very busy, they have to observe the asteroid close to the earth several times a day, repeat its trajectory and moving speed, and strive to get the accurate time and closest distance of its passage through the earth as soon as possible.

At present, the asteroid is about 249,500 kilometers away from the Earth, and it is moving at a speed of about 32,000 kilometers per hour, which is very fast, which gives it enough energy to climb out of the Earth's gravitational well, and also makes it safer.

Based on its current trajectory, it will continue to move closer to Earth in the coming days, but will remain within a safe distance, which is predicted to be no less than 0.4 Earth-Moon distances.

There should be a partial solar eclipse and the massive asteroid at a very close distance.

Under normal circumstances, the monitoring station would not pay so much attention to the asteroid passing through the earth, but this time the asteroid is indeed too large, so they have to be cautious. Once this asteroid with a diameter of 40 kilometers becomes a threat to the Earth, even a little bit is likely to cause huge consequences.

On the screen of the monitoring station, the computer is simulating the trajectory of the asteroid, while dozens of researchers on both sides are busy calculating and analyzing the data in their hands.

"How's it going. ”

A calm voice rang out beside a researcher.

"Huh?" the researcher looked away from the paper at hand and to his side, and when he saw the man standing beside him, he immediately gathered his thoughts and replied.

"For now, the asteroid is safe, it has a lot of mass and velocity, and theoretically it won't be pulled by Earth's gravity. ”

"Well, that's good. The man was wearing a white coat and leaning his gold-rimmed glasses, with absolute sanity and calmness in his eyes.

"Continue to observe, and report anything abnormal as soon as possible. ”

"Yes. The researcher nodded.

At this moment, next to the two of them, another researcher was looking at the operating data calculated on the computer.

He seemed to see something, his brow furrowed, and he leaned down to the computer to carefully look at a line of data.

After a few seconds, his pupils dilated slightly, and a fine layer of cold sweat broke out on his forehead.

"Report, report. ”

"What's wrong?" the man on the side turned around.

The researcher, who seemed to have discovered something, leaned on the table and swallowed a mouthful of saliva.

"The trajectory of the asteroid seems to have been deflected. ”

As he spoke, he raised his eyes with some horror in his eyes.

"It's deflecting towards the Earth. ”
