Yunyushan walked alone on the way out of school, and most of the classmates around him were in groups.

"Hey, Yushan, why are you walking so slowly?"

A boy put his arm on his back and greeted him warmly.

"Oh, it's nothing, I just like to go slower." I couldn't think of any good reason for it, so I could only cope like this.

The two of them chatted a few words with or without a match, and a voice came from the front:

"Bai Leshan, hurry up."

So the two immediately said goodbye.

"See you tomorrow, bye."

"Oh okay, bye-bye"

Looking at his distant back, Yun Yushan didn't feel too much, he had only been here for less than two months, and as a transfer student, it was naturally difficult to have a particularly good friend so quickly.

The sun shines on the water, sparkling, like a school of glowing fish. He often had the illusion that he became a beam of light, shining on the water, and was refracted by the waves on the surface of the water into countless rays of light and flew towards the vast starry sky.

Looking up, he seemed to be in space, seeing the rugged surface of the moon, and seeing the sun like a blazing fireball.

He is usually the only one in the house, so he walks more slowly, and it is a great pleasure for him to pass the time with those fantasies on the road.

But his fantasies soon came to an end, as he arrived home.

And the moon, which he had just gazed at, floated silently in space, and there was no more movement except for the occasional visit from humans and meteorites.

On the far side of the moon, the day was as dark and cold as usual.

A saucer-shaped transparent object gradually emerged in mid-air, and by the time it fell to the ground, it had completely become an entity, and a saucer-shaped alien spaceship in the human impression was parked there.

A door appeared on the ship's smooth and flawless surface, and two strange-looking aliens stepped out of it.

The two aliens spoke fluent Chinese dialect, which was extremely grotesque. Obviously, for their technology, even without a medium, sound can travel freely.

"This is the Blue Star, it's so beautiful."

"It's really beautiful," the other alien muttered without a look, "It's a pity that no matter how beautiful it is, I can't see it anymore, Qing." ”

"Maybe we can admire it a little longer, the sea."

"Hmph, you just like to do things that don't make sense." The alien known as "The Sea" was visibly displeased.

"You don't seem to be happy with me?"

"Sort of"

“……”

The humans of Earth do not yet know that they have come to a catastrophe, and for them, today is the same as any other day.

At Yunyushan's house, make dinner, take a bath, do homework, sleep, and then wake up.

The sun is rising, the golden morning light is scattered in the city, and the city that has been silent all night is beginning to wake up.

Yun Yushan met the enthusiastic aunt downstairs and greeted him, in fact, Yun Yushan felt that they were not familiar with each other, but everyone else greeted him, and he always had to respond to be polite.

"Auntie, it's early."

The old woman sends her grandson to school, and she is used to it every day. After sending the child to the farmer's market to buy groceries, he suddenly realized that he had forgotten to bring his wallet, and he couldn't help but feel sorry for his stupidity.

"Why did you forget to bring your wallet today?" The old woman was a little upset, and suddenly a bus drove behind her, and when she saw that it was the one she was going to take, she hurriedly chased after her, and hurriedly got on the bus. Sitting on the bus, I saw that my grandson was going to elementary school next year.

In the elementary school, the whole school is filled with a lively atmosphere, and today is the sports day held by the school. The loudspeaker buzzed to broadcast the ranking of the runners, a few children on the track blushed and ran desperately, and the classes cheering for the players in their own class on the side were full of voices and fever, which made it unbelievable that these people were children.

An office worker passed by the school gate, heard the sound and couldn't help but look a few more times, came back to his senses and looked at his watch, and hurriedly walked to the subway station. After a while, the office workers who crowded into the subway looked at their mobile phones, looked at them for a while, and they were bored, but they didn't know what they wanted to see. When he arrived at the station, he got off the bus with the crowd and came to the company to clock in and go to work, in order to work in the current company, he had struggled, and there was always a drive in his heart at that time, but now those motivations have disappeared with the promotion of his status.

Now I am also in charge of a project on the detection of thermal radiation, but I don't have to work so hard anymore.

Not long after the office workers who had just arrived at the office settled down, the phone rang.

The other end of the phone: "Xiao Liu, how is the progress of the project you have at hand, you have to come up with a plan as soon as possible......"

"I know there is a difficulty, overcome it, the customer is urging me."

On the other end of the phone, the leader who had just finished calling the office workers dialed another number: "Hey, Professor Lin......

This person known as Professor Lin looks like he is in his forties, but his aura is not weak: "I hope that the instrument will be ready for prototype production within two weeks, and I don't have to worry about money......"

"Okay, okay, don't worry, within these two weeks, the prototype will definitely be released."

Professor Lin hung up the phone, sat in a chair and rubbed his eyes, the recent progress of the experiment was delayed again and again, which made him very helpless.

Time passed quickly, and it was almost time to get off work again, and Professor Lin's group had been working overtime for a few days, and he was embarrassed to ask everyone to continue working overtime.

"Teacher Lin, you can't rush the things you are studying, you might as well take a good rest while you are free." The boy in the white coat who stood next to Professor Lin said.

"Okay"

Professor Lin sorted out the experimental data, and after the students left, carefully locked the experimental materials in the safe, which was a gray stone chip.

On the way home, Professor Lin has been thinking about the experimental data, comparing the characteristics of other substances, Professor Lin is almost certain that this is a new substance, at least a new material, only experimental proofs and papers are published, but I heard that Lao Wang, who is engaged in genetic engineering, is also studying this kind of stone chips, Professor Lin is puzzled, why is it popular in this year.

At Professor Lin's house, his son Yun Yushan also happened to come home from school, and the two met in the corridor, but they didn't have the atmosphere of an ordinary father and son, so they didn't have anything to say, and they entered the house together.

Professor Lin and his wife divorced, left when Yunyushan was a child, plunged into his own research, almost never saw his ex-wife and son for more than ten years, last year his ex-wife died suddenly and unexpectedly, Professor Lin was quite surprised, but also a little helpless, he can only take on the responsibility of raising his son.

Yun Yushan is a fairly independent child, when he returns home, he is almost always doing dinner and housework, Professor Lin has lived alone for so many years, looking at his son's skillful movements in front of him, he can't find a chance to help.

And Yun Yushan, who lives with his mother all the year round, is very eager for his father's love, but he doesn't know how to get along with his father, and he is still a little shy when he has just become an adult, and he usually doesn't take the initiative to chat with his strange father, so he has to keep doing housework and not letting himself be idle.

At this time, the two aliens on the moon were still chattering.

"One hundred and thirty-three years ago, if I hadn't gone to Brooks Star to save you, you would have become the excrement of the Brooks Star people long ago!"

"Hmph, you died in the silent sea of stars in the previous generation, didn't I risk my life to come out with your message, can you still talk to me here like now?"

"I'll save you more!"

"Nonsense......"

As the two aliens argued, the saucer's hatch opened again, and a dark shadow emerged from inside.

"Qing and Hai, you two are really boring, you've been arguing for a whole day and a night, and it's not over yet."

This creature standing in front of the two aliens looked exactly the same as the Chinese people on the earth, with hazy eyes, yawning, and looking like he had just woken up.

"Forget it, it's still hopeless to rely on the two of you, so I'll do it." Raising his hand and pointing at the earth, a green light flew out of his fingertips.

"The development of that civilization on the Blue Star is not bad, there must be a lot of life energy, don't waste it, refine it for a hundred years first, and then we will come to get energy crystals before the end of the holiday."

"Hey, Shiro, are we still lacking this energy?" The alien named "Qing" pursed his lips, "Wouldn't it be okay to just blow up the blue star and get the energy crystal?" ”

Hai glanced at Bai and remembered the green light that shot out just now, thoughtfully.

"Forget it, Qing, white is also a good intention, doesn't he always say that no matter how small the mosquito legs are, they are meat."

"Well, okay, okay, that's the trouble." Qing didn't bother about it anymore, but said: "You have to listen to my ...... wherever you go during the holidays."
