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

Time passed by minute by minute.

Twenty seconds later, a piercing siren sounded in the command center.

"Professor, received a signal from Ross 154 on the frequency of 1420 megahertz."

Lu Yongchang took a deep breath.

coming!

The other party responded!

[Hello, little ones, I have been following you for a long time. 】

Chapter 329 No Maliciousness?

With just one sentence, the atmosphere in the command center instantly became colder.

At this moment, an old advertisement even sounded in Lu Yongchang's mind.

Cool through the heart, the heart is flying.

"A long time... what does this mean?"

Fang Xu's slightly hoarse voice came: "Could it be that the other party has been paying attention to us since the earth?"

"If that's the case, the level of technology on the other side..."

He didn't finish his sentence.

But everyone present knew that this meant that, in the eyes of the other side, human civilization was as humble as ants on the side of the road.

Perhaps because of the response, Ross 154 sent a steady stream of complicated messages.

[According to your time calculation, it should be 64 years ago when your detector disturbed my deep sleep. 】

[Take a star system that is about to be destroyed as an information transfer station...]

【Ha ha……】

[This approach is very good, very cautious. 】

[In this universe, it is right to be cautious. 】

Lu Yongchang gasped suddenly.

What did he see? !

In order to hide their own coordinates, the previous efforts of human civilization, in the eyes of the other party, are as clear as a blank sheet of paper!

It's not just Lu Yongchang, at this moment, the command center has become a mess.

"Quiet!"

Lu Yongchang looked at the holographic projection in front of him with an ugly face: "Zero, did the other side send any other messages?"

"Professor, there is no new information."

"Cut off all signal interfaces." Without any hesitation, Lu Yongchang issued an order directly, "Start the self-inspection program immediately."

"Focus on checking all the data sent back by interstellar probes in the past 64 years!"

"The signal interface has been cut off." Zero's voice sounded again, "The system self-test is in progress..."

Looking at the self-inspection progress bar in the holographic projection, Lu Yongchang's eyes were full of horror.

What a big deal!

For an interstellar civilization, the difficulty of achieving long-distance hacking is no different than reaching the sky in one step.

As long as the other party does not receive the information you send, even if you have great abilities, you will not be able to hack into the computer system of the enemy civilization.

Just like, no matter how powerful a hacker is, he can't hack into a computer that is not connected to any network from a distance and out of thin air.

For the interstellar civilization, before communication is established, both parties are like a computer without access to the network.

But all of this will change completely with the establishment of the communication system.

This is also what Lu Yongchang is worried about.

64 years ago, the probes sent by humans were invaded by this advanced civilization.

The other party even discovered the information transfer station carefully set up by humans!

And use this to learn the human language and master the human calculation unit...

What a terrifying thing this is!

Thinking that in the past 64 years, human civilization has lived under the surveillance of the other party, and layers of cold sweat ooze from Lu Yongchang's back!

"The detection is complete."

"No potential hazards have been identified."

Hearing this, Lu Yongchang breathed a sigh of relief.

He raised his hand, wiped the cold sweat from his forehead, and sat down on the chair behind him.

"Click."

At this moment, the sound of the electromagnetic adsorption device was particularly loud.

"Professor, the other party sent another message, do you accept it?"

Zero asked in a flat tone.

Lu Yongchang didn't speak for the first time.

After thinking carefully, he asked softly: "Zero, if the other party has hacking behavior, can you detect and stop it? What is the probability of success?"

"..."

After a short wait, Zero's response came: "According to the simulation calculation, I am 99.9% sure to prevent the other party's hacking behavior."

Lu Yongchang raised his eyebrows, a trace of surprise flashed in his eyes: "So tall?"

"Yes, Professor." Zero said again, "I have sufficient home field advantage, and I can even physically cut off the source of the hacking signal."

"That……"

Lu Yongchang thought for a moment and said: "Open the signal interface and receive the information sent by the other side."

[Don't be nervous, I just learned some basic information with the help of the detectors you sent, and I didn't tamper with your central computer system. 】

[If you don’t believe me, you can test the central computer system. 】

[Trust me, I have no malicious intentions. 】

Seeing the Chinese characters appearing in the holographic projection, Lu Yongchang sneered.

This is not malicious?

They all secretly learned all the basic information, and said that they didn't have any malicious intentions?

The dog would shake his head when he heard this!

Although he thought so in his heart, Lu Yongchang carefully edited a bunch of new information in a respectful tone.

[Dear high civilization, I'm sorry we disturbed your rest. 】

[We believe that with your ability, you should disdain to attack our little secondary civilization. 】

【It’s just that we have a few doubts that we would like to ask you to answer. 】

【Who are you?What level of civilization does it belong to?What do we need to do? 】

[If there is any offense, please forgive me. 】

……

"Yongchang, these questions..."

"Is it too straightforward?"

Fang Xu frowned, and asked in a low voice: "Will it cause the other party's dissatisfaction?"

After the previous dialogue, the weight of this unknown civilization in the hearts of everyone has been infinitely elevated.

no way.

The opposite side has this strength.

Before humans have discovered him, he has already figured out humans clearly.

Once you annoy the other side...

Human civilization, presumably, will not have any good fruit to eat.

Lu Yongchang shook his head slowly: "No."

"Since the other party chooses to communicate with us, it will inevitably tell us some necessary information."

As he spoke, he pressed the send button in front of him.

……

After dozens of seconds.

The familiar 1420 MHz signal came from the direction of Ross 154.

[Interesting... You guys actually know the civilization classification system. 】

[It seems that you should have encountered other civilizations. 】

【let me guess. 】

[Have you just experienced a war? 】

In the holographic projection, Chinese characters jumped out one by one.

Lu Yongchang's face changed slightly.

"Yongchang..." Fang Xu turned his head suddenly, his eyes flickering with horror, he lowered his voice, and whispered in an extremely hoarse voice, "Why don't we leave this star system?"

"Not urgent."

"Wait and talk first." Lu Yongchang squeezed out a few words from between his teeth, "Be prepared to attack and evacuate."

Hearing this, Zhao Zijie, who was sitting next to him, straightened his back instantly, and his face became a little serious.

He slowly stretched out his hand and pressed it on the holographic projection in front of him.

As long as there is any abnormality, as long as he gives an order, the human fleet will launch the most powerful attack on Ross 154!

At the same time, except for the attack starship, all other starships will enter the state of [Forward [-]]!

The way forward, random!

As for the purpose, it is naturally to preserve the last fire for human civilization!

[Hehe, I said that, you should be nervous again, right? 】

[Believe me, I still won't do anything to a small second-level civilization. 】

Chapter 330 Level [-] Civilization: "Painting"

The rows of Chinese characters in the holographic projection caught everyone's eyes.

Lu Yongchang's face was pale, and he wanted to get up subconsciously, but was firmly sucked to the seat by the electromagnetic adsorption device.

Even if the central computer system wasn't hacked, even if they weren't living under each other's watch...

However, in front of this unknown civilization, human civilization at this time is still like a stripped lamb, without any privacy at all.

He didn't even dare to imagine what the mental state of this advanced civilization was like during these 64 years!

Is it with the mentality of teasing ants, or with some other twisted mentality...

Lu Yongchang didn't dare to think about this question carefully!

"Zi, Zijie, wait first." Lu Yongchang took a few deep breaths, suppressed the panic in his heart for a few minutes, and stopped Zhao Zijie's attempt to press the attack button.

Just like Lu Yongchang, Zhao Zijie's eyes were sunken at this time, his face was pale, and there were beads of bean-sized cold sweat on his forehead!

But there are still differences between the two.

In Zhao Zijie's eyes, there was a madness and fierceness!

Like an animal driven to a dead end, it is full of madness to choose and eat!
