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

He glanced at the "dictionary" in front of him, smacked his lips and explained.

"Look."

"This part of the pattern on the right."

"It's a cesium-133 atom."

"And this pattern represents the transition of the cesium-133 atom between its two hyperfine energy levels in its ground state."

"As for what it means..."

"One second is the duration of 1 cycles of radiation when a cesium-133 atom transitions between two hyperfine energy levels in its ground state, so the text on the left corresponding to it is one second and the cesium-9192631770 atom meaning."

"Similarly, 1 meter is the distance light travels in 1/299792458 seconds in a vacuum."

"By analogy, through this dictionary, we can recognize their words little by little, so as to understand the content of their information."

Chapter 180 Refused to Respond

As members of the People's Federation, the brains of everyone present are naturally better, and they quickly understood Lu Yongchang's statement.

"It means that in order to let us understand the meaning of their message, Proxima Centauri sent a detailed commentary?"

Councilor Li leaned his elbows on the conference table, and asked with a frown: "What is their purpose?"

After all, this is the first time in history that human civilization has come into contact with an alien civilization.

No one, including Lu Yongchang, knew how to deal with this situation.

"Wait a little longer." Lu Yongchang frowned and said, "Wait for Ling to analyze all the content of the message before reading."

The old man sitting on the main seat nodded silently, with a flash of thought in his eyes.

"The extremely dark way of getting along with cosmic civilizations that you mentioned last time does not seem to be very suitable for this situation."

During the waiting time, the old man said softly.

Hearing this, Lu Yongchang couldn't help but smiled wryly: "Chairman, this is also the result I deduced based on the situation at the time."

"This time... I don't know what's going on."

Suddenly, his eyes moved slightly: "Perhaps, they are also like us, a rudimentary interstellar civilization that has just stepped out of the planet?"

"No, no."

Thinking of the traces of the Hall thruster on the moon, Lu Yongchang quickly overturned his argument: "The junior interstellar civilization does not have such a high level of interstellar navigation technology."

In the conference room, the faces of every congressman were full of worries and doubts.

"Professor, the analysis result is out."

Zero's voice broke the slightly restless atmosphere in the conference room.

"For the convenience of understanding, I translated it according to the way humans write."

As he spoke, a "translation" appeared in front of everyone present.

[To the unknown advanced civilization: We are the Proxima Centauri civilization 4.22 light-years away from you.

In the vast universe, it is extremely lucky to encounter an advanced civilization with a similar level of development.

Unknown advanced civilization, I wonder if you have encountered a "technical bottleneck"?

Regardless of whether we meet or not, we hope to establish a cooperative relationship with you, and jointly analyze the endless mysteries in the universe, so as to achieve the rapid development of civilization. 】

At the end of the translation, the relative coordinates of Proxima Centauri and the solar system are also attached.

The moment Lu Yongchang saw the relative coordinates, his eyes lit up slightly.

"Like us, do you use multiple pulsars for positioning..." Lu Yongchang muttered to himself, "There is still a technological bottleneck, what does this mean?"

"Professor, this is a brand new vocabulary." Zero quickly explained, "I chose the most appropriate translation based on the context and the dictionary."

"Probably the meaning is very simple. When a civilization develops to a certain level, it will encounter the so-called development bottleneck, and the development of science and technology will come to a standstill."

"The time to encounter technological bottlenecks depends on the development potential of civilization."

"In their opinion, there are many factors that affect the development potential of civilization. The population size, the proportion of scientists, the emphasis on technological development, and even belief and willpower all have different degrees of influence on it."

Lu Yongchang's face changed slightly.

The stagnation of technological development is tantamount to slow death for a civilization!

Especially the rudimentary interstellar civilization that has just stepped out of the planet!

Watching the surrounding resources being exhausted, but unable to go further afield to find new resources...

Thinking of this scene, Lu Yongchang shuddered slightly.

Fortunately, human beings have not yet encountered the so-called technological bottleneck.

Of course, this also has a lot to do with the technology tree system in his mind.

"Yongchang?" Perhaps seeing Lu Yongchang's uncertain expression, Mr. Li asked softly, "Is there any important content hidden in this message?"

Lu Yongchang came back to his senses, and stared straight at the four Chinese characters for "technical bottleneck".

Suddenly, his eyes lit up!

Each clue formed a complete closed loop in his mind!

"Chairman, I know what's going on!"

Lu Yongchang was full of excitement, and said without the slightest hesitation: "If their technological development has stalled, then their behavior makes sense!"

Seeing the puzzled expression on the old man's face, Lu Yongchang hurriedly explained.

"Chairman, you should still remember the basic conditions of the dark forest law I mentioned last time?"

The old man was taken aback for a moment, and then suddenly said: "The law of the dark forest...the name is quite good."

"I remember the few basic conditions you mentioned."

"It seems that there is a chain of suspicion and a technology explosion, right?"

Lu Yongchang nodded, with a strange light shining in his eyes: "Now, they no longer have the prerequisite for technological explosion!"

"So, that's why they chose to communicate with us?" The old man frowned. "How can they ensure that we are good-hearted?"

Hearing this question, Lv Yongchang smiled more intensely.

"That gets to the point."

"I can be sure that the civilizations on the Proxima Centauri side, like us, are contacting alien civilizations for the first time."

"On the scale of the universe, everyone is a newcomer who has just left Novice Village!"

"Then what are we going to do now?" Albert's voice sounded from the side, "Respond to them?"

The moment Albert's voice fell, the conference room fell into silence.

Need a response?

What are the consequences of responding?

How to ensure that the Proxima civilization did not deceive them?

If the Proxima Centauri civilization is malicious, what will be the consequences if they respond rashly?

Councilor Li's expression changed slightly.

For the first time, he personally felt the endless chain of suspicion.

Unlike on Earth, the infinite extension of the distance between the two makes the chain of suspicion infinitely stronger!

The conference room was extremely quiet, and the sound of the wall clock swinging continuously reached everyone's ears, aggravating the restlessness in people's hearts.

Lu Yongchang silently felt the atmosphere in the conference room.

After a long time, he let out a long breath and said softly, "I choose not to respond to them."

The muscles on Albert's face trembled slightly, and he understood the meaning of Lu Yongchang's words.

"You mean... preparing for war?"

Lu Yongchang nodded silently, affirming Albert's question.

"Why did you choose war?" A low-ranking member of parliament interrupted the communication between the two dissatisfied, "The civilization of Proxima Centauri is now more technologically advanced than ours?"

"Even they have encountered technological bottlenecks, in case we later..."

"There is no chance!" Lu Yongchang's voice suddenly became louder, "Even if we also encounter technological bottlenecks, it is also a matter of human civilization!"

"The top priority now is that we need to find a planet in the habitable zone to house those billions of humans!"

"Do you think the Proxima Centauri will obediently give us their home planet?!"

The congressman didn't answer, but just silently lowered his head.

"do not forget."

Lu Yongchang looked a little cold: "It is the responsibility of the Academy of Sciences to deal with matters outside civilization!"

Chapter 181 Destructive Mining

As Lu Yongchang's voice fell, many congressmen's faces turned ugly.

what is this?

Is the purpose of their coming to the meeting just to listen to an announcement?

"Cough cough!"

Seeing that something was wrong with the atmosphere in the meeting room, Councilor Li, who was sitting in the main seat, coughed twice.

Seeing that all the councilors were looking at him, the old man said unhurriedly: "I think what Professor Lu said makes sense."

"Humans, there is no chance to try and make mistakes."

"Since it has been confirmed that there is a civilization in the Proxima Centauri star 4.22 light-years away, from now on, we must prepare for the war in the near future."

"Remember, you are a member of humanity!"

"I don't want someone to get their ass wrong on such a big issue of right and wrong!"

Faced with Mr. Li's severe reprimand, the expressions of those councilors who originally advocated cooperation with Proxima civilization changed drastically.

Sitting crooked ass...

In this context, it is tantamount to a crime against humanity!

Seeing the coldness in the old man's eyes, all the congressmen present swallowed subconsciously.

……

The information from the Proxima Centauri civilization makes the future of human civilization seem more and more illusory.

Before leaving the solar system, human beings have a potential life and death enemy.

No, to be precise, there should be two.

There is also a civilization that causes sun mutations, which has not been revealed until now.

Thinking of this, Lu Yongchang who returned to the office sighed silently.

Everyone is the enemy!

This universe is so dark!

As the saying goes, blessings come without pairs, and misfortunes never come singly. When Lu Yongchang was troubled, Ling's voice once again added a little haze to his mood.

"Professor, there is bad news."

"What's wrong?" He took a deep breath, sat up straight from the office chair, and asked solemnly towards the holographic projection in front of him.

"Professor, according to the current construction progress, our ore resources will be completely exhausted in two weeks."

"How come?" Lu Yongchang frowned suddenly, "Aren't there many robots mining?"

"Professor, the ore veins that are easy to mine on the surface have basically been mined." Zero controls the holographic projection to present a scene of scenes, "Most of the remaining ore veins are deep and difficult to mine."

Looking at the huge tiankengs in the video, Lu Yongchang fell silent.

Although the Moon Palace project has been implemented, the entire moon is covered with large and small automatic mining factories.

But the earth is still the current mainstream ore source for human beings.

If you want to obtain a large amount of ore easily, perhaps, you can only find a way from the sky.
