After Luo Xun and Zhang Xiaobin went out.

Chen Yi took out Lin Qian's personal information again and looked through it carefully.

The age of 20 is the time of youth and flourishing.

Although some thoughts and ideas are still a little immature and naïve.

But the talent and ability are very good, and the thinking is relatively sharp.

It should not be a big problem to sharpen it and become the core personnel of Yifei in the space age.

"You said that you established a connection with the target through the public password of the universe, and then analyzed the life form of the other party through the information replied by the target, and said your specific thoughts."

Chen Yi closed the information with both hands.

looked at Lin Qian, who was sitting not far away, and asked the key to this question.

The universe public password, this thing, Chen Yi knows what it is.

To put it simply.

That is, all civilizations, all life, are under the same universe.

In this way, all civilizations have a natural set of common codes.

For example, in mathematics, the mathematical symbols may be different between different civilizations, but the formulas and theorems described between these symbols will be the same for all civilizations.

1+1=2, which is the universal formula of the universe.

As long as it is a circle, the area of the circle is a certain ratio of circumference to diameter, multiplied by the square of the radius.

Binary, ternary, quaternary, decimal and other mathematical laws and theorems are also common among every civilization in the universe.

There will be no situation where the binary of human beings and the binary of extraterrestrial civilizations are different.

All kinds of physical laws, Newton's first law, Newton's second law, Newton's third law, as well as the nuclear parameters of various elements, the theory of relativity, the mass-energy formula and so on, everyone is also in agreement.

For example, the definition of time, the current international definition of 1 second time, is not a clock ticking.

Rather, it refers to the time spent by the cesium-133 atom in the 9192631770 electromagnetic wave radiation cycle when it transitions between two energy orders in the ground state.

Of course, other civilizations may not know which cesium-133 atom human civilization depicts.

But because they are in the same universe, all cesium-133 atoms and atomic structures are the same.

In this way, it is only necessary to note the nucleus of the cesium-133 atom, how many neutrons and protons there are.

Well, the alien civilization understands.

Oh, it turns out that 1 second for human beings is 9192631770 times the time it takes for the cesium-133 atom to transition to radiation cycle.

Knowing 1 second, the next thing you can know is 1 minute, 1 hour, 1 millisecond, 1 nanosecond, and so on, and the definition of time is agreed.

Time to reach a consensus.

Next, the same goes for length.

Extraterrestrial civilizations may not know how long a human is 1 meter.

But extraterrestrial civilizations going into space must know how long the diameter of the hydrogen nucleus, that is, the diameter of the proton.

Using the diameter of a proton to describe 1 meter, for example, 1 meter is equal to how many hydrogen atoms are arranged together, so that extraterrestrial civilizations understand the concept of the length of meters.

There are two basic concepts of time and length.

Other definitions of velocity, acceleration, force, gravity, etc., can be further extended and agreed upon.

Got the speed, time, length, etc.

The rest of the colors and sounds can be agreed on in the same way.

With color and sound, drawings and images have the basis for simultaneous translation.

and all other basic concepts were agreed, and images and pictures were also agreed.

The following subjective concepts such as far, near, long, short, light, and heavy can be translated step by step and consensus established through the comparison of pictures, images, etc., with the comparison of data.

Subjective concepts can be determined, and further actions, behaviors, cultures, and even art can also be built on these subjective concepts to build the basis of translation.

For example, the day in Chinese.

Understand the rules of human physics, mathematical theorems, and the definition of elements.

Extraterrestrial civilizations will understand that the sun is a star where a large amount of hydrogen comes together due to gravity and the elemental fusion occurs, that is, the meaning of the star.

Further, by understanding the human definition of color, sound, and image, the alien civilization will understand that day means day.

Further, by understanding the human definition of action through speed, images, etc., and then through the metaphor of images, the chemical formula changes when organisms reproduce, and understanding the process of human reproduction, alien civilizations can understand the third meaning of day.

Eventually, the language dictionaries of both sides were interoperable.

A common set of linguistic codes was formed between the two civilizations.

Through this set of passwords, combined with powerful computing power and artificial intelligence, all interstellar civilizations can communicate smoothly with each other, and there are no longer communication barriers.

"Mr. Chen, different civilizations and intelligent life, because of the different living environments, differences in social culture and values, there will be different differences in aesthetic hobbies and cultural preferences."

"These aesthetic and cultural differences, unless deliberately concealed, will inevitably be revealed in normal communication and communication."

"Determine the other party's aesthetic preferences, cultural preferences, etc., we can use these to extrapolate backwards and analyze the other party's living environment and social mainstream values."

"Determine the living environment of the other party and the mainstream value of society, and then analyze it further, we can analyze the life form of the other party, innate personality and so on."

Lin Qian briefly described her thoughts.

"What if the other party disguises their aesthetics and culture in the process of communication?"

"Or, what if they don't pay attention to our communications at all?"

Chen Yi nodded and said the flaws in this plan.

Lin Qian's plan sounds very simple.

However, it involves complex knowledge of life evolution, intelligent psychology, artistic aesthetics, social engineering, etc.

Speaking from his heart, if he were Chen Yi, he would not be able to do such an analysis plan.

For Xuannu to carry out such an analysis, a lot of learning and modeling analysis are also indispensable.

After all, there is a specialization in the art industry.

What he is good at now is scientific research, black technology, and what he is good at is engaging in machine and research, as well as a lot of knowledge and basic principles, and he has cultivated a view of the universe.

Of course, as the founder of Wingfly, the leader of the space age.

In addition to researching black technology, his current core responsibility is to grasp the development direction of human civilization, rather than doing something personally.

It doesn't matter if he can't do such a plan, as long as someone below can do it.

If he had to do everything himself, he would not be able to lift human civilization into space if he was tired to death.

"If the other party's response is disguised, or there is no response to our message."

"Don't hesitate, the winged fleet can set off first."

"21 light hours, according to the other party's speed it takes 69 days, and a communication back and forth is 42 hours, we can reserve 20 days to communicate with the other party more than a dozen times."

"The information and data of more than a dozen communications are enough to analyze all the situation of the other party."

"If you can't analyze the situation, or if you analyze the probability of the other party's malicious civilization, it is relatively high."

"Yifei arranged for the fleet to pass in the name of greeting, and at the same time asked the other party not to approach the inner solar system and not to approach the blue star."

"In this way, even if the other party is malicious, the war will not affect the blue star and our base camp."

Lin Qian clearly stated the response plan for different situations.

Regarding Lin Qian's performance, Chen Yi was not in a hurry to express his opinion, his fingers knocked on the table, and said calmly: "You go out first and let Luo Xun call." ”

Lin Qian didn't say anything, bowed slightly to Chen Yi, got up and went outside.

After a while, Luo Xun came in.

Chen Yi did not deny it because the other party's emotional control ability was relatively poor at the beginning, and the other party's Tinder plan.

After all, the existence of memetic technology is still top secret, and no more than ten people in the world know about it.

Not knowing the existence of memes, in the face of an alien civilization that can fly across the stars, it is normal logic to be cautious and prepare the Tinder battleship.

As long as he didn't say that he was going to leave with the Tinder battleship.

"For this unknown blueshift signal, as a member of the External Relations Department, in addition to the Tinder Project and the Global Defense Array, what other ideas do you need to add?"

Chen Yi motioned for Luo Xun to sit down and asked if the other party had any other ideas and plans.

"Mr. Chen, I think we can arrange for the battleship of Yifei to go over to greet you."

Luo Xun thought about it and made a proposal.

"What about after greeting?"

"Determine the reality of the opposing fleet and prepare for the next move."

"What action?"

"If the strength of the opposing fleet is stronger, our warships can also delay for a while, increasing the success rate of our Tinder plan."

"If the strength of the opposing fleet is on par with ours or even weaker than ours, we can try to establish diplomatic relations with the other side to increase our understanding of the universe and the stars."

Luo Xun talked eloquently, Chen Yi listened for a while, pondered for a moment, and made a fork in his heart.

The program is well complemented.

But they did not understand the fundamental responsibilities of the Department of External Relations.

In other words, this scheme is suitable for direction rather than actual implementation. However, if the direction is guided, it is superficial, lacking an overall view and a strategic view.

"Very good, you go back first and call Zhang Xiaobin in." After Luo Xun finished speaking, Chen Yi nodded, signaled that the other party could go out, and at the same time called Zhang Xiaobin in.

"Yes."

Luo Xun replied with some disappointment, turned around and went outside.

After waiting for a while, Zhang Xiaobin came in.

Chen Yi still asked the same question, asking if there were any ideas that needed to be added.

Compared with Luo Xun's eloquent talk before, Zhang Xiaobin is more straightforward, and there is no other supplement.

Instead, according to the current position of the eight planets in the solar system, a defense and offensive plan relying on planetary resources is given, and the plan for him to take the initiative to attack and resist the enemy is filled in and perfected.

How perfect is it?

It is so perfect that the front-line combatants can almost execute and use it when they get it.

“.”

Chen Yi was silent for a moment, and looked at Zhang Xiaobin, who looked a little fanatical: "You should go to the Development Department, not the External Relations Department." ”

"The development department has certain requirements for engineering, and my achievements in engineering are not enough, and my mastery of intelligent psychology and social engineering meets the requirements."

Zhang Xiaobin told the truth, and he didn't mean to put gold on his face.

"I understand, since you don't have enough engineering grades, you should stay in the External Relations Department."

Chen Yi nodded, and did not comment on Zhang Xiaobin's behavior of choosing that subject if he couldn't do it.

The development department, or the construction and combat department of Yifei Future, has a hard index for engineering.

After all, in the future war system, it is not only about commanding, but also about restarting the flame of war and building and developing alone.

Even the latter is one of the centers of gravity in the future.

Because of the space environment, it is empty.

The technology of the two sides is the same, the two sides are almost the cards, coupled with the assistance of artificial intelligence to check and fill in the gaps, it is difficult to have a situation where one person can defeat thousands of troops by relying on tactics

In this case, the test of victory in the war is more about whose productive forces are more fierce, whose resources are replenished more quickly, and whose scientific and technological strength is stronger.

"You go back first, today's matter, pay attention to confidentiality."

After determining Zhang Xiaobin's situation, Chen Yi motioned to the other party to go back first.

"Thank you, Mr. Chen."

Zhang Xiaobin looked a little disappointed, but he didn't say anything, bowed slightly and turned around to leave the office area.

"Called Lin Qian in."

Watching Zhang Xiaobin leave, Chen Yi thought for a moment and instructed Qin Xiaoyu.

"Okay, Brother Yi."

Qin Xiaoyu answered, got up and went outside.

After a while, he brought Lin Qian, who was waiting in the hall next to him.

"The Universal Public Dictionary is ready."

"What do you think should be our first greeting, and what do we need to prepare?"

Seeing Lin Qian coming in, Chen Yi was not polite, and directly asked the other party about his thoughts and ideas.

First sentence.

Lin Qian thought seriously for a while, and replied with a somewhat cautious expression: "Friends from afar, this is carbon-based intelligent life human civilization, may I ask you if there is anything you need our help with?" ”

"As for preparation, first, increase tracking of the situation and determine the reaction of the other party to the signal."

"The second is to determine the response time of the other party."

"The public dictionary of the universe, although it does not involve complex operations, because of the huge amount of data and a certain amount of abstraction, if you want to understand it quickly, you can't do without the assistance of strong artificial intelligence."

"The speed at which the other party replies to the message, to a large extent, represents the strength of the other party in the field of artificial intelligence."

"Of course, there is a certain possibility of camouflage in the speed of recovery."

"We can add some relatively complex and obscure sentences that can test the performance of artificial intelligence in follow-up exchanges to judge whether the other party's first reply is disguised."

"If the results of the test are inconsistent with the results of the first response, and it is determined that the other party is disguised, then the probability that the other party is malicious will be greatly increased."

Lin Qian answered and analyzed clearly.

Human civilization has just entered space, and it is unknown to any situation in the universe.

Now if you want to make contact with an alien civilization that is unfamiliar and has a high probability of being stronger than yourself, you would rather have 10,000 more eyes and a thousand more temptations, which is better than being a stunned young man.

"Good."

Chen Yi praised approvingly, looked at Lin Qian and said with a smile: "Congratulations, classmate Lin Qian, you will represent human civilization and send a formal inquiry to aliens for the first time." ”

"History will remember today, and it will remember your name at the same time."

"Ahh

Lin Qian shouted in disbelief, and her expression was suddenly full of indescribable excitement.

"Xuannu, prepare a cosmic public dictionary of human civilization, activate the interstellar communication array, and send an inquiry to the unknown blueshift signal according to Lin Qian's meaning."

"Send 10 times, 1 minute apart."

"At the same time, record the time of sending, strictly determine the distance of the other party, and determine the response interval of the other party."

"Turn on the tachyon scanning module, turn on the electromagnetic wave detection module, increase the scanning frequency of the Hubble telescope, and determine the various behaviors of the other party after receiving the signal."

Chen Yi gave instructions to Xuannu one by one.

Received Chen Yi's command, far away in space.

The interstellar radio communication array, which is arranged in a planet-synchronous orbit, begins to slowly adjust its angle.

After multiple angle corrections, the transmission direction of the communication array accurately locks the unknown blueshift signal direction beyond 21 optical hours, and then emits a series of electromagnetic wave signals
