Zhang Yuan sighed: "But I think the reason for deep space colonization is still insufficient. Dyson spheres, it does sound scary. However, it is a direct proof that there is a truly powerful extraterrestrial civilization in the universe. Civilization can be exposed. ”

"It also proves that the universe is not a black forest and can communicate with each other. It's not as dangerous as you think. ”

In the 21st century, before it was proven to be a Dyson sphere, scientists were already enthusiastically sending electromagnetic signals in that direction. Anyway, scientists often do this kind of thing.

This string of signals represents the "cordial greetings" of mankind and the wish of "yearning for peace".

This kind of thing is ridiculous, and it is said that there is no "yearning for peace", even though mankind has broken out two world wars in the 22nd century. But it did happen.

There are always a lot of optimists in the world who believe that aliens can communicate amicably. If the real communication is successful, human civilization will usher in a qualitative change!

"How can you be so optimistic, a strong civilization can be exposed, and a weak one? The earth will always be played to death by them, so why should people help monkeys? ”

Li Zhendong said with a smile, this kind of bullshit has happened too much, so it's not strange.

To this day, there are still people who are sending electromagnetic waves in the direction of KIC 8462852, hoping that the "alien god" will help them out of the sea of suffering.

Secretly emitting electromagnetic waves, the government has no way and no ability to stop it.

Zhang Yuan also teased: "Maybe? People on the South American side will eat monkeys; But the people on our side do help the monkeys, and when they see the sick monkeys, they will rescue them and give them food. Monkeys even have the audacity to grab things, and you will be fined for hurting them......"

"It is estimated that in a while, aliens will come to Earth to drop food."

"Well, that's pretty good...... When the time comes, don't say it's really fragrant. ”

Fortunately, electromagnetic waves travel only at the speed of light, and it takes more than 1,200 years to reach the KIC 8462852.

In addition, the attenuation of electromagnetic waves in cosmic space is very serious, plus cosmic radiation interference, and when it reaches 1,200 light-years away, it has long become a string of garbled codes.

So there is no need to worry too much, it is impossible for ordinary civilian equipment to transmit the signal so far.

Whether the earth is exposed or not, no one knows.

Perhaps, people have observed primitive people tens of thousands of years ago, and they don't care about this group of indigenous monkeys at all.

Looking up at the starry sky, Zhang Yuan felt a little sleepy. He yawned, and suddenly clenched his fists as if he had been beaten with chicken blood: "So, study!" ”

"You have to become stronger to evolve from a monkey to a human."

"Fighting, come on! Step up your game! ”

“……”

Li Zhendong wanted to cry without tears, so he rested for a few minutes, and he wanted to study again.

What to do, online, etc., it's in a hurry!

But soon, Zhang Yuan rejected the idea by himself, "Forget it, it's too late, it's not efficient, let's rest first." I will always sleep back when I squeeze out the time, so it is better to have a regular schedule. ”

Li Zhendong's heart was relieved.

"I'll report to Xisha Aviation City tomorrow."

Li Zhendong was nervous again: "Why? Your holiday is mandatory and does not allow early ending! ”

"There's nothing to do at home...... I finished reading the book. ”

Zhang Yuan shook his head and explained: "It's too expensive to buy e-books yourself, and the universities there can read books for free. Coupled with the fact that there is a lot of literature that can be consulted for free, and there are some professors and experts who can ask for help, it is not a good thing to work alone behind closed doors. ”

In this era, intellectual property rights are highly valued, and piracy is illegal, and if you are caught, you will be fined heavily.

Specialized books and essays are more expensive. According to Zhang Yuan's current speed of reading books and literature, he has to consume hundreds of thousands of yuan every day.

So my plan was to read two books a day, plus five literatures, for 20 days. Tens of thousands of dollars are also money...... Why don't you save some money and donate it to the Deep Space Foundation? ”

Li Zhendong felt that his head was about to explode, and he almost fainted on the ground.

Read two books a day......

Two books......

Two......

You're a dog, right, and books are meat and bones?

He felt that he was not good at all, and said nonsense: "You are such a dog...... Oh big guy! ”

"That's it, sleep and sleep."

Watching Zhang Yuan walk into his room, Li Zhendong took a hard breath.

Thinking of being busy picking up girls during the holidays, playing games, and playing stupid sisters, while others are reading, working hard, and working hard, I feel a sense of guilt in my heart.

Then, he picked up the half-read book "Complex and Half Single Plum Algebra" and re-read it.

It's so angry.

…… Forced, no way.

……

Early the next morning, Zhang Yuan got up early, bid farewell to Li Zhendong's parents, and returned to his city.

After enduring the pain and buying a series of the latest electronic products, he copied all kinds of data left by his father into 10 mechanical hard drives.

After 3,000 years of interstellar travel, nothing is reliable, and electronics are especially unreliable. Maybe one day, this tablet will not be able to be used, and only by diversifying the risk can this data be maintained for a long time.

Even if after three thousand years, these things have long been worthless, Zhang Yuan still hopes that they can be preserved.

I checked back and forth several times: "That's all there should be." ”

The Deep Space Planning Agency allows each astronaut to carry 20 kilograms of personal supplies. The suitcase was stocked with a few changes of clothes, a few souvenirs left by my father, and all kinds of messy electronics, including the latest photonic chips, storage devices, etc., which should not be too much to miss.

"Hey, I'm going to get out of here soon......"

Zhang Yuan looked at this home, where he had lived for more than ten years, every detail was so familiar.

I've laughed here, wept, been taunted by my father, and been depressed alone in my room...... There have been so many, so many stories that have happened.

It's like its own mother, and there's a harbor-like warmth when it's hiding here.

Unfortunately, I was going to leave it eventually.

There is no possibility of regret if you never go back.

Clean up and wipe every place spotlessly, and throw away all the garbage that should be thrown away.

"Bang" closed the door, and the deep attachment in my heart became more and more intense.

He turned his head and bowed.

"Goodbye."

"Goodbye!"

Farewell to the past, farewell to the past, a tear can't help but flow.

Zhang Yuan wiped his sleeve and walked to the elevator.

Men always have to go far away, wipe away their tears, and don't think about anything.

Dragged his suitcase to the entrance of the community, where there was a familiar park, because the weather was too hot, and there was no one in it.

I remember when he was a child, he used to play here.

One day, he suddenly fell on the ground.

Then I had a flash of inspiration and cried into the corner, and I couldn't stop.

When his father asked him what he was doing, Zhang Yuan said, "I knew I was going to die, so I cried." Even if you don't die now...... I'm going to die a long, long time later, so it's very uncomfortable. ”

A little child, who suddenly understood the concept of "death", did not turn a corner for a while and a half, and felt very uncomfortable in his heart, so he could only keep crying.

This situation seems funny and real.

Death, how unfortunate it is, is the end of everyone.

"I see...... "Daddy said coolly, "if you're dead, you're dead, what's the big deal?" Do you know what it means to be alive? If you don't know, why be afraid? ”

"Live, to eat!" Zhang Yuan snorted and cried.

"Hahaha, that makes sense!" Daddy was just there laughing, and in a rare case he didn't make any comments.

Smart as a dad, he can't answer such an ultimate question.
