In the vast space of the Perseus Arm, one of the main spiral arms of the Milky Way, a narrow trail of smoke spread forward at a speed infinitely close to the speed of light, like a sharp blade cutting through the galaxy, leaving gray scars on the galaxy. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

And it's a spaceship.

It has a sci-fi silvery shell and slowly rotating quadrives, with an oval sphere glowing white in the middle.

Inside the spaceship, a metallic robot is constantly downloading and uploading information.

"Targeted, the blue planet in the star system in the Orion Arm, the third spiral arm of the Milky Way."

"Attack: Gravitational Wave Attack!"

"Attack stopped...... Redefining the potential of civilization...... Identified as a mutant civilization...... Loading quantum information...... Redefining the Attack Method...... Quantum-guided attacks. ”

At the microscopic level, the light quanta vibrated slightly, and then calmed down, as if nothing had happened.

……

On the beach in Sanya, Xiao Li and Xi Jiqiu were wearing swimsuits and playing beach volleyball, flirting and scolding from time to time in an envious gaze.

"What do you want to eat tonight?"

"Is it okay to eat you?"

"Not good."

A young man lying under a parasol wearing large sunglasses glanced at his girlfriend next to him, and then at Xi Jiqiu, who was stepping on the beach and raising his hand, jumping, and hitting the ball, and hatefully biting on the straw was a wild suck, "Flowers are stuck in cow dung...... Good cabbage is arched by pigs! ”

"Show affection and die quickly." The middle-aged uncle squatting on the shallow water looked at the two of them intently, and cursed in circles, "Show so well, tomorrow, no, I will be hit by a car and killed by a plane when I wait a minute." ”

"That's enough." A young man waved a tennis racket hatefully, and resentment was rampant in his heart, "Half a month, half a month in a row to show affection here, it's just enough." ”

At this moment, a small dotted shadow appeared on the beach, and then, the shadow quickly expanded, and a helicopter was faintly visible in the sky.

The middle-aged uncle squatting on the shallow water looked at the helicopter dumbfounded, "This is not true, is it...... I'm just talking about it...... When did it work so well...... ”

The helicopter stopped steadily on the beach, and two soldiers in military uniforms jumped down from it, standing in front of Xiao Li with a serious face, and one of the soldiers took the lead in speaking, "Academician Xiao, I'm very sorry to disturb your vacation, but there is a very urgent matter that you need to deal with." ”

Another soldier also spoke, "Just last night, the joint quantum research team in Vienna, Austria, accidentally discovered a piece of information while conducting quantum teleportation research. ”

Quantum teleportation is a long-distance communication method based on quantum entanglement, which is simply a transmission method that disperses quantum entanglement and some physical information to convert it so that it can reach any specified place, which is the basic form of quantum communication.

"What's the message?" Xiao Li asked.

"A message from an extraterrestrial civilization." The soldier who spoke pondered his words and said, "A very friendly message, but it expresses something that makes the Federation high-level undecided, so the Federation has ordered us to come and find you, after all, you have been in contact with extraterrestrial civilizations and have exposed their plots, so the Federation high-level would like to ask you to refer to it." ”

"Academician Xiao, I know you're on a blind date...... Cultivating Emotional ...... But now is not the time to cultivate feelings...... The upper echelons are now frightened birds...... We need pillars. ”

"And that pillar is you."

"That's an exaggeration." Xiao Li was embarrassed, "Wait a minute, I'll deal with some things." ”

He walked back and walked in front of Xi Jiqiu, "I'm sorry, maybe I can't continue to play with you, but I did have a lot of fun during my vacation in Sanya." ”

"So I'll give you a meeting gift, and Fu Xi will send you this meeting gift when you go back."

"It's okay." Xi Jiqiu is not an eyeless girl, she knows what to do at this time, "You go and get busy with yours, I will take a plane back to the imperial capital tonight." ”

With that, she got up and left.

Looking at the back of Xi Jiqiu's departure, Xiao Li turned around and nodded to the two soldiers when he couldn't see it anymore, "Please take me to the place where I first found the information, I want to see the most primitive information." ”

With that, he got into the helicopter.

Buzzing......

The propeller buzzed and spun, carrying Xiao Li across the South China Sea, across the Strait of Malacca, and finally landing in front of the laboratory of the Joint Quantum Research Group in Vienna, Austria.

Xiao Li got off the plane, and someone was already waiting for him here, with white skin, a high nose, blue glass-like eyes rolling in their sockets, and bald hair.

"Hello, Xiao." When the bald man saw Xiao Li coming down, he immediately greeted him and stretched out his hand to shake Xiao Li's hand, "I am Bell, the head of the Joint Quantum Research Group in Vienna, Austria, and welcome Academician Xiao to the Joint Quantum Research Group in Vienna, Austria." ”

Saying that, he lured Xiao Li in, "Here's the thing, last night when our group was studying quantum teleportation, we accidentally discovered a piece of information transmitted through quantum. ”

"It sent us some very kind messages."

"A message of kindness?"

"Yes, well-intentioned information, at least on the surface."

Before he entered the laboratory, Xiao Li saw the antenna, a giant antenna, which was placed on the roof of the laboratory, which was bigger than the roof.

"This is the antenna designed by our research team ourselves, the main purpose is to receive and transmit quantum information, for sensitivity considerations, so the design is a bit huge." Bell said with a hint of pride.

In Europe, there are many groups like him, although they belong to a certain organization, but they are only affiliated with each other, and the talents and funds need to find their own way, and being able to do this is enough to make them proud.

What's even more exciting is that they have discovered information about extraterrestrial civilizations, which means that they are beginning to become famous.

"It's this giant antenna that allows our group to receive information from extraterrestrial civilizations."

Xiao Li nodded and didn't say anything, the quantum realm was not his strong point, and it was inconvenient for him to express his opinion in this regard, "Can you take me to see that piece of information?" ”

"Absolutely."

Bell led Xiao Li to the inside of the laboratory.

The laboratory is not very vast, and the small space is densely packed with computers, and these computers are not the supercomputers that Xiao Li often uses, but rather ordinary commercial-grade servers.

These commercial-grade servers may be more powerful than ordinary computers in terms of computing, but they are not worth mentioning in the face of supercomputers.

"Abel, this is Xiao, he wants to see the information we received unexpectedly."

"Okay."

A white man named Abel quickly tapped his fingers on the keyboard and pulled up a piece of information.

"The Galactic Guardians Alliance warns you that the civilization located on the blue planet in the star system in the third spiral arm of the galaxy, Orion, the third spiral arm of the galaxy, your coordinates in the universe have been exposed, and you may usher in a dark forest strike, warning, warning, this blow comes from a higher civilization."

"Is this a warning message?" Xiao Li touched his chin, "But what is the Galactic Guardian Alliance, why haven't I heard of it?" ”

He had traveled the soul network of the colonizer civilization and collected some information about the galaxy, but he had never heard of the Galactic Guardian Alliance.

"Literally, yes." Bell took Xiao Li's words, "The investigators of the Earth Federation also muttered a warning message when they copied this information. ”

"But does such a well-intentioned civilization really exist?" Xiao Li is very calm, once he was bitten by a snake for ten years and was afraid of the well rope, after experiencing the lizard civilization, the dark forest strike and the cyborg, he has long been naïve.

There may be well-intentioned civilizations, but it would be naïve to believe that the civilizations you encounter are well-intentioned.

"Can you capture where the source of quantum information is?" Xiao Li asked.

"How could it be ......." Bell smiled bitterly, "In terms of quantum communication, we are still in a very early stage, and we can't even build the most basic quantum network...... Tracing the source of quantum information is such a difficult technology, how can we have the ability to do ....... ”

Xiao Li thought for a moment and then asked, "Then what about sending a message?" ”

"That's fine." "We can transfer information through quantum, but I can't guarantee where the information will go ......," Bell affirmed. ”

The accurate means of quantum transmission is quantum teleportation, and they still have some achievements in this regard, but they cannot accurately orient to the specific location.

If quantum teleportation is compared to a human shouting, then the technology they currently master is limited to standing on an empty field and yelling at the air, while the complete quantum teleportation is the transmission of the sound of the martial arts master in the martial arts novel, condensing the sound into a thin line, and accurately transmitting it to anyone's ears without causing information leakage.

"Try it." Xiao Li said calmly: "It doesn't matter if you fail. ”

"What message should we send?"

"One question: What is the Galactic Guardians Alliance?"

"Okay." Bell and his colleagues are busy, translating the information they want to send into quantum information.

The so-called transformation of information into quantum information is actually a special algorithm.

It is inspired by the binary of computers.

As we all know, the basis of a computer is binary, consisting of 0 and 1, which basically represent the information displayed by the computer, and the same is true for quantum information, which is composed of the most basic information, and then converted into information that can be understood by human beings through computer calculation and reduction.

As the quantum information transformation was complete, Bell and his colleagues passed it on.

No one knows where the message will go, disappear in space, spread farther away, or inexplicably turn back.

The transmission of quantum information has too many unsolved mysteries for human beings today.

"What is the Galactic Guardians Alliance?"

"What is the Galactic Guardians Alliance?"

"What is the Galactic Guardians Alliance?"

Quantum is vibrating, information is transmitting, it is like human beings shouting towards the universe, representing the spread of human voices to the universe.

After about two seconds, the message was sent back.

"The Galactic Guardians Alliance is an alliance of well-meaning civilizations, and it is our duty to defend against the Cleaners and protect the weak ones."

"He really did reply." Bell leaned on the computer and stared at it carefully, "No traces of intrusion, not hackers...... It's someone who communicates with us through quantum information. ”

He was excited.

Because it means that quantum communication has a future, and it is a very bright future.

"And ......." Bell couldn't help himself, "Being able to transmit quantum information in a directional manner, the other party's quantum teleportation technology is very mature, they are definitely an extraterrestrial civilization, and they are also a very advanced extraterrestrial civilization." ”

"Calm down." Xiao Li, who has been in contact with extraterrestrial civilizations several times, is excited about the communication of extraterrestrial civilizations, but he is not so excited that it is difficult to control himself, "Ask him, how do you prove that they are well-intentioned civilizations?" ”

"Okay."

Bell tapped quickly on the keyboard, converting Xiao Li's words into quantum information and sending it out.

But this time, it took a full minute for the message to come back.

"We can't prove ourselves."

Xiao Li continued expressionlessly: "Ask them, what is a cleaner. ”

Bell quickly tapped on the keyboard, and soon the message came back, "The Cleaner is a spaceship sent by a malicious civilization to clean up a weak civilization, and it flies around the universe at an infinitely close speed of light, cleaning up all the weak civilizations it has seen along the way, and it is their creed to escape far away after one blow." ”

"Why clean up?"

"Because the universe is vast and the living space is very narrow, the big trees in the forest do not allow the weak weeds to rob them of their nutrients, because they need it too."

Hearing this, Xiao Li and the people present all gasped, and a chill poured out from the bottom of their hearts, and then their whole bodies were cold.

The big trees are the higher civilizations, the weeds are the new civilizations of them, and the higher civilizations that have gone far in the development of civilization go back to clean up those new civilizations that have started in the mountains, and the malice of civilization is terrifying.

"Those damn cleaners, for this reason, actually launched a dark forest strike on the earth." Bell was indignant.

"What about you?"

"We are a civilization of good will."

"Why kindness?"

"The universe is vast, the living space is vast, and the big trees and weeds in the forest can survive together because the nutrients are abundant."

Hearing this, Bell breathed a sigh of relief, "It seems that this civilization is indeed well-intentioned. ”

There are good and bad, there is malice and goodwill, and to be able to meet a civilization of goodwill, Bell feels that he can celebrate.

"Not necessarily." Xiao Li said calmly: "Ask him again, why didn't they make a move against the destruction of the lizard civilization?" ”
