Tao Yuda's words echoed in the command center.

Lu Yongchang frowned and said after pondering for a moment.

"you mean……"

"The opposite side is just a first-level or second-level civilization like us?"

"Yes, this possibility cannot be ruled out." Tao Yuda nodded and said in a deep voice.

"No, no."

He Bilin's voice of objection came from the side: "Academician Tao, according to your words, what does the second sentence mean?"

"Why do the other party call us little guys?"

"Isn't this a contradiction to the previous sentence?"

Tao Yuda raised his lips slightly and said softly: "In my opinion, this is a trick that the other party deliberately arranged."

"The purpose is to confuse our judgment."

"But how do you make sure that the first sentence is not a fool?"

He Bilin asked directly without any hesitation.

Tao Yuda's expression suddenly stopped.

This is indeed a problem.

Lu Yongchang, who was in the first place, sighed slightly, waved his hand helplessly to interrupt the argument between the two.

This is the chain of suspicion...

Just a few short sentences can cause endless questions.

"Okay, in this regard, I suggest that the other party be recognized as a civilization with little strength than ours."

"And, for some reason, the opponent's war power should be greatly reduced."

"In other words, it is a level 3 or level 4 civilization in a broken state."

Lu Yongchang's conclusion immediately attracted everyone's attention.

Facing everyone's puzzled eyes, he explained softly.

"Everyone should understand what Tao Yuda and He Bilin said."

"There is a huge contradiction among these two names."

"From the two names, we can see the other party's cautiousness in civilization."

"on the other hand."

"It can be seen from the other party's second sentence that the other party immediately discovered our attempt to attack Ross 154."

"And we have not found any trace of the other party's civilization until now."

"The interstellar probe next to Ross 154 also found nothing unusual."

"Based on the above two points, we can roughly draw a conclusion."

"The other party should be a high-level civilization whose strength has been greatly damaged due to unknown factors."

"This so-called unknown factor may be war or civil strife."

Everyone's eyes showed a sudden look and nodded in agreement.

Fang Xu frowned and suddenly said, "Yongchang, if you want to consider the title, should the other party's claim be taken seriously?"

“The other party uses a claim to be ‘me’, not ‘we’.”

"Does this mean that the other party is an individual of a high-level civilization?"

"If we were just individuals of advanced civilizations, could we..."

Speaking of this, a cold light flashed in Fang Xu's eyes.

Lu Yongchang instantly understood the meaning of Fang Xu's words.

At this moment, his heart beat a few times.

If it is really as Fang Xu said, the other party is just an individual of a high-level civilization, then humans may be able to rely on their huge fleet...

But soon, he suppressed the throbbing in his heart and slowly shook his head.

"No, I don't recommend doing this before the other party completely reveals his malicious intentions."

"If the other party is just an individual of a third-level civilization, we may still have the power to fight."

"But if it is an individual of Level 4 or even Level 5 civilization... I don't think we can win by relying on the advantage of quantity."

"Think about our current starships, think about the starships of Proxima Centar civilization before."

"It's just that the gap between first-level civilization and second-level civilization is so big."

Fang Xu nodded silently, with a hint of regret in his eyes.

If it can sink or capture a starship from a high-level civilization, the development speed of human civilization will probably increase by a huge margin in an instant.

"Now, it's the second question."

Lu Yongchang shrugged and spoke again.

"What the other party said was not malicious, how should we understand?"

"You can't believe them!" Fang Xu said immediately, "Thinking about the outcome of the solar system and the Proxima Galaxy, I don't think a strange higher civilization can have good intentions to us."

Lu Yongchang pondered for a moment and nodded gently: "Then how should we deal with the exchange initiated by this advanced civilization?"

"Ignore it?"

“Or…responsive?”

The moment the question was raised, everyone present was moved.

The first person to speak was Academician Cao Liangcai.

"I don't think we can respond to each other's communication."

“This will have some unpredictable consequences for us.”

"This consequence may be fatal to human civilization."

Fang Xu's voice also sounded: "Since the opponent has chosen to communicate with us, we should take the opportunity to learn about each other's information."

“We have too little understanding of the universe.”

The moment Fang Xu finished speaking, Lu Yongchang's eyes moved slightly.

This is not wrong.

The current human civilization has too shallow understanding of the universe.

If you can take this opportunity to learn about the superficial information of various civilizations in the universe...

I think it will be of great help to the subsequent development of human civilization.

Thinking of this, Lu Yongchang reached out and pressed in the air: "Everyone, be quiet."

The debate in the command center quickly became smaller.

"Try to contact the other party first."

Lu Yongchang said lightly: "No matter what, we need an opportunity to understand the civilization in the universe."

"Otherwise, the situation of human civilization will only become more and more difficult in the future."

His speech put an end to the debate.

Even Cao Liangcai nodded silently after hearing the reasons given by Lu Yongchang and agreed to the proposal.

...

One hour later.

A message was sent from [Earth] and flew straight towards Ross 154, 5.8 million kilometers away in the distance.

The information content is very simple.

【Hello】

There are only two words, and there are even punctuation marks.

Lu Yongchang stood on the podium, staring at the holographic projection ahead.

In the holographic projection, there is a real-time image of Rose 154 from the interstellar probe.

After 19.33 seconds.

Looking at the image in front of him that had not changed at all, Lu Yongchang's brows frowned.

"Calculate the time, the other party should have received the signal."

"Why didn't there be any reaction?"

Time passes by minute by minute.

Twenty seconds later, a harsh alarm sounded in the command center.

"Professor, received a signal from Ross 154 with a frequency of 1420 MHz."

Lu Yongchang took a deep breath.

Here comes!

The other party responded!
Chapter completed!
