Age of Cataclysm: I can light up the technology tree

With just one sentence, the atmosphere in the command center instantly turned cold.

At this moment, an ancient advertising slogan even sounded in Lu Yongchang's mind.

My heart feels cool and my heart is soaring.

"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 beginning of 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 from the opposite side, human civilization was as humble as ants on the roadside.

Perhaps because of the response, a steady stream of complicated messages came from the direction of Ross 154.

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

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

【hehe……】

[This is a very good and cautious approach. 】

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

Lu Yongchang took a sharp breath.

What did he see? !

In order to hide its own coordinates, the previous efforts of human civilization are as clear as a piece of white paper to the other party!

Not only Lu Yongchang, but at this moment, the command center was already in chaos.

"Quiet!"

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

"Professor, there is no new information."

"Cut off all signal interfaces." Lu Yongchang gave the order without any hesitation, "Start the self-test program immediately."

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

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

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

Something big happened!

For interstellar civilizations, the difficulty of achieving long-distance hacking is tantamount to reaching the sky in one step.

As long as the other party doesn't receive the information you send, you won't be able to hack into the enemy civilization's computer system no matter how powerful you are.

For example, no matter how powerful a hacker is, he cannot hack into a computer that is not connected to any network from a distance or out of thin air.

For interstellar civilizations, before communication is established, both parties are like computers without access to the Internet.

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

This is also what Lu Yongchang is worried about.

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

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

And thereby learned human language and mastered human calculation units...

What a terrifying thing!

Thinking that during these 64 years, human civilization has lived under the surveillance of the other party, layers of cold sweat oozed from Lu Yongchang's back!

"Detection completed."

"No potential hazard has 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 seemed particularly loud.

"Professor, the other party has sent another message. Do you want to accept it?"

Zero asked in a calm tone.

Lu Yongchang didn't speak for the first time.

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

"..."

After a short wait, Zero's response came: "Based on simulation calculations, 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 high?"

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

"That……"

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

[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 it, you can test the central computer system. 】

[Believe me, I mean no harm. 】

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

Is this no malice?

You have secretly learned all the basic information, and you still say you have no malicious intentions?

When the dog heard this, he would shake his head!

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

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

[We believe that with your ability, you should not bother to take action against our small second-level civilization. 】

[Just, we have a few questions that we would like you to answer. 】

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

[Sorry for any offense. 】

…

"Yongchang, these questions..."

"Isn't it too straightforward?"

Fang Xu frowned and asked in a low voice: "Will it cause dissatisfaction on the other side?"

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

no way.

The opponent has this strength.

Before humans discovered him, he had already figured out everything about humans.

Once you annoy the other party...

Human civilization, I guess, will not have any good fruits to eat.

Lu Yongchang slowly shook his head: "No."

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

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

…

Tens of seconds later.

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

[Interesting... you actually know the civilization classification system. 】

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

[Let me guess. 】

【Have you just experienced a war? 】

In the holographic projection, Chinese characters pop up one by one.

Lu Yongchang's face changed slightly.

"Yongchang..." Fang Xu turned his head suddenly, with a look of panic in his eyes. He lowered his voice and murmured in an extremely hoarse voice, "How about we leave this star system?"

"No rush."

"We'll talk first." Lu Yongchang squeezed out a few words through his teeth, "Be prepared for attack and evacuation."

Upon hearing this, Zhao Zijie, who was sitting next to him, straightened his back instantly and his face became a little more 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 starships, all other starships will enter the [Forward Four] state!

The direction of travel is random!

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

[Haha, when I say this, you must be nervous again, right? 】

[Believe me, I won’t take action against a small second-level civilization. 】
