It's reasonable for me to have a two-way foil for a second-level civilization, right?

The next scene made his thinking organs tremble more and more violently.

A blue planet and a silver moon.

The probe landed quietly on the silver-white satellite.

High-precision cameras have captured images of intelligent creatures on the blue planet.

so ugly.

Atoka looked at the image in front of him, pouted.

They have only one pair of eyes!

Limbs are so weak, I don't know how they live...

Incredible!

Atoka talked to himself while looking at the image on the monitor.

The video data came to an abrupt end.

Atoka knew that this was the return of the probe.

He stood up abruptly and walked towards the communication equipment beside him.

He needs to report the incident to the higher-ups.

……

When it comes to alien civilizations, the efficiency of the upper class has suddenly increased a lot.

Just after Atoka finished reporting and put down the communication device, the reminder sound of the communication device sounded.

"..."

Atoka silently picked up the communication device, and put it next to his hearing organ.

"Are you sure?"

"……Okay, I know."

After putting down the communication equipment, Atoka's breathing hole opened and closed, and balls of hot air gushed out from it.

The upper class speaks really badly.

I just confirmed a sentence, and I was scolded.

Wrinkles appeared on the top of Atoka's thinking organ, and he silently walked towards the console beside him.

There is no way, I am just a low-level receiver, one Atoka is gone, and there are tens of thousands of Atoka to take over his job.

Thinking of this, the folds on the top of Atoka's thinking organ became much less.

Just do what the higher ups say!

As he thought about it, he pressed a button on the console with an "expressionless face".

The electromagnetic wave signal passed through the dense atmosphere and was transmitted to a man-made device outside the atmosphere.

In the next second, the signal amplified by the equipment flew towards the solar system!

…………

Take a look at the timeline.

In 1980, the Proxima b probe was launched.

In 2025, when the Earth Voyager left the solar system, the probe arrived in the solar system, and sent out a signal after detection.

In 2030, Proxima b received the signal from the probe and sent the above signal in the same year.

In 2034, Earth receives a signal from Proxima Centauri.

Chapter 179 "Dictionaries"

Earth.

Qinghai-Tibet Plateau, People's Federation First Laboratory, inside the main laboratory.

Lu Yongchang stared blankly at the holographic image in front of him, and swallowed slightly.

"...Zero, what did you say?"

"Signal in the direction of Proxima Centauri? Are you sure?!"

Lu Yongchang was confused.

How could this be? !

In the last life, there was no signal from Proxima Centauri!

Is the butterfly effect really that powerful? !

"Yes." Zero Yong said in a very affirmative tone, "Because of the transmission distance, the signal is a bit mixed, but I can be sure that this is a message sent by an intelligent creature!"

Hearing this, Lu Yongchang's face changed slightly.

He got it!

In the previous life, maybe Proxima Centauri also sent a signal!

It's just that the signals are too complicated, and human beings just discovered the sun mutation at that time, the world was in turmoil, and no one noticed the signal!

Lu Yongchang looked at the regularly fluctuating signal frequency band in front of him with an uncertain expression.

"zero!"

"Immediately notify the chairman of the assembly to hold a meeting of the People's Federation."

"Also, point all working radio telescopes toward Proxima Centauri and keep an eye on their movements!"

……

conference room.

The chairman of the council and one of the councilors sat solemnly in their seats, silently looking at Lu Yongchang standing in front of them.

"Yongchang, is the zero report true?"

Seeing that everyone was present, Mr. Li asked in a low voice with a look of concern in his eyes.

Lu Yongchang nodded silently.

Then, he turned around and waved to the holographic projector beside him.

A holographic image appeared in front of him.

"This is the signal received by the sky eye system."

"At present, there may be some confusion." Lu Yongchang said in a deep voice, "Zero, let's process the data."

The moment the order was issued, the messy signal bands instantly became regular.

Looking at the undulating waveform in front of him, the meeting room was dead silent.

Albert, who was sitting by the side, reached out and scratched his blond hair, and said in fluent Chinese: "Then what does this signal contain?"

"It can't be just a series of ordinary electromagnetic wave signals?"

Lu Yongchang glanced at Albert and said calmly, "That's exactly what I want to say."

"At present, the content of this signal is very simple."

As Lu Yongchang's voice fell, a series of numbers appeared in front of everyone.

2 3 5 7 11 13 17 19 23 2 3 5 7 11 13 17 19 23

"This is the law of signal change from zero statistics."

"Sequence of prime numbers?" The Emperor asked in a low voice, frowning slightly.

Lu Yongchang raised his eyebrows slightly, and looked at the emperor in surprise.

"Yes, it is indeed a sequence of prime numbers."

"From 2 to 23, as of now, this sequence has been cycled 30 times, and each cycle takes 1 minute."

"I don't understand." Albert tugged at his blond hair, his eyes full of doubts, "Why does Proxima Centauri put such a boring string of data?"

Like Albert, many congressmen also showed some doubts in their eyes.

"I think this should be selecting the audience." Lu Yongchang replied softly, "or, it is selecting the audience."

"How should two civilizations communicate, this is a very romantic question."

"Two civilizations with different cultures, different technologies, and different species will definitely not be able to communicate normally if they rely solely on language or patterns." Lu Yongchang took a deep breath, "In the entire visible universe, at least, in our Within the cognitive system, the laws of mathematics and physics are the only tools.”

"Prime number sequence plus electromagnetic wave communication, this can at least filter out those civilizations that have not developed modern technology."

"Considering the things found on the moon, I can be sure that this series of signals from Proxima Centauri must be directed at us."

As soon as the voice fell, there were countless questions.

"The moon? What was found on the moon?"

"Look at what I'm doing? The United States didn't find any messy things when they landed on the moon before!"

"..."

Mr. Li frowned and coughed lightly.

"Cough cough!"

"Zero, unlock that file."

The next moment, a series of small holographic images appeared in front of every congressman.

"Everyone, let me explain." Councilor Li picked up the microphone and said in a deep voice, "This is the trace discovered by Xia Guo when he landed on the moon for the first time."

"According to our calculations, this burn mark should come from a more advanced Hall thruster, and the destination of this UFO is Proxima Centauri."

After a brief silence, exclamations sounded in the conference room!

"Damn..." This is the quintessence of the country that Albert MP shouted.

"God!!" This is the exclamation of the emperor.

Although he knew that the occasion was wrong, Lu Yongchang still had a smile in his eyes when he saw the scene in front of him.

It seems that the chairman's cultural unification plan has been implemented well.

"They, what do they want to do!" Albert was shocked and angry.

This reaction is also normal.

No matter who it is, when they know that there is a civilization secretly observing human beings, they will react like this.

"Professor, the second message has arrived."

Just when Lu Yongchang was about to answer, Zero's avatar suddenly appeared above the conference table.

"What's the content?!" Lu Yongchang asked in a deep voice with a serious face.

The originally noisy meeting room also fell silent in an instant!

"There's a lot of information." Zero's avatar frowned anthropomorphically, "However, they attached a dictionary inside."

"Dictionary?" Lu Yongchang asked suspiciously.

"Yes, in my opinion, this is a dictionary." Zero replied quickly.

At the same time, the holographic projection screen quietly changed.

On the left side of the holographic projection, there are pieces of weird text.

On the right, there are some simple patterns.

"So that's how it is..." Lu Yongchang's eyes showed a bit of obsession.

Everyone looked at the chief scientist of the People's Federation who was deeply involved.

"This..." Albert and the Emperor looked at each other and shrugged helplessly.

Even Mr. Li's face was full of puzzlement and doubts.

"Yongchang?" Finally, Councilor Li couldn't help asking, "What does this mean?"

Hearing Mr. Li's call, Lu Yongchang came back to his senses.
