This day is an important day that determines the fate of mankind!

Yu Yifeng stood in front of the recording table and took a hard breath, his heart still beating wildly. He can be said to be the most mentally endurable person on the Noah, but he is still extremely nervous.

Although the temperature inside the ship remained around 23-24 degrees Celsius, he still felt the impatience welling up in his heart. It was hot, it was hot, and he felt like he was sweating all over his body. He was genuinely nervous, trying to calm his mind.

"Tough" and "camouflage" are the main keywords of this plan, and in the whole process, human beings must not show any breath of stage fright!

In fact, a human being is just a cat, but if you have to disguise yourself as a tiger, you have to roar from time to time to prove that you are a real tiger...... That's how humans feel today.

According to the calculations of scientists, in the universe, after two civilizations with a similar level of scientific and technological development, the greatest possibility is ...... Mutual temptations and skirmishes! Then the two sides found that the cost of going to war with each other was too great to make peaceful contacts. exchanging information with each other, trading with each other, etc......

It is not known whether the Dark Forest theory is correct or not. But from the standpoint of humanity, if the benefits of war are less than the price to be paid, then war will not break out.

In the final analysis, all human actions are for the sake of profit, and perhaps the same is true of other civilized races.

Assuming that interstellar civilizations are scarce, then species that can develop interstellar navigation capabilities must be very intelligent. If this assumption is true, everyone can sit down and talk about it, and there is no need to fight you to the death. Death is something that any living thing wants to avoid, and there is no need for hatred and war.

But that being said, people don't know if the other person is logical, moral, or belligerent......

People can only use their wisdom to the extreme and implement the plan with the greatest success rate!

"The other party should be wise and logical, otherwise science and technology will not be able to develop. It's not too wrong to see them as smart species......" Yu Yifeng took a deep breath, they wanted to communicate with each other according to this thinking.

The first step in the "camouflage plan" is communication, or rather, deterrence!

Just like countries that live in peace, they also have borders with each other. A powerful interstellar civilization will certainly not let an alien spaceship with unknown circumstances boldly approach it. According to this logic, human beings must preemptively warn each other, rather than blindly hiding.

Only in this way can you show that you are a powerful civilization with the same status as the other party!

So, how to warn? How to warn hard and just right? This has become the focus of the discussion among experts in the past few days.

After careful discussion, they came to the conclusion that they would be the first to send signals to extraterrestrial civilizations by radio!

Just like all countries on the earth, when fishing boats and planes cross the border, they will inevitably give a warning in righteous words, and if they do not heed the warning, deeper contradictions will occur......

Well, things may not be the same in the universe. Either way, such a warning is the most human-logical solution...... If the universe is not a dark forest, there must be nothing wrong with warning first!

“…… We are a strong human civilization! Be calm and calm! Yu Yifeng kept silently reciting this sentence in his heart, and began to calm the restlessness in his heart.

People don't want to use text and telegraphy, because human information encoding ability is not high, maybe in the eyes of extraterrestrial civilizations, it is a symbol of weakness...... In this way, it is likely to be directly exposed. Sending a string of voice messages does not have this problem, as long as the sound waves are recorded as completely as possible, using the simplest encoding.

Yu Yifeng's tone can't be too hurried, nor can he be anxious, he can be slightly angry, like equal parties telling a serious matter: You have crossed the line, leave quickly, otherwise it will cause a war. Yes, that's it...... We are both equal!

After a long time, he slowly spoke: "Unknown alien spaceship, you have crossed the safety limit set by us, leave quickly!" If you don't leave, you will be responsible for the consequences! ”

Yu Yifeng finished speaking in one breath, feeling that he had performed well this time.

He listened to the recording a few more times, but found no major errors. If his voice is timid or anxious, he will have to re-record it, and this is the third time he has recorded it.

The wording in this is very particular, such as "demarcated safe distance" and "borne by you", which is just pulling the tiger's skin and scaring people......

Many of the scientists below began to nod, and one of the leading psychology experts said, "That's it, there shouldn't be much of a problem this time." ”

In fact, aliens absolutely cannot understand Chinese. With the information of this sentence alone, no matter how powerful the other party's technology is, it is impossible to decipher the relevant meaning. Especially Chinese, which is the most difficult language for humans to learn!

But it doesn't matter, they don't need to understand, just let them know - humanity is warning them!

This is also a point of the mystery of the human "camouflage" plan...... The unknown is the most terrifying thing, and alien civilizations do not know what human beings are talking about, and they will definitely have certain concerns and questions.

In this way, they will have an incomprehensible psychology towards humans, and the best result is to scare them away!

The experts are getting busy, and they will send this voice message through a large radio station. This radio station has a power of up to 30,000 watts, and the other party can certainly receive it clearly.

"Captain! The speed of radio propagation is also the speed of light, and it takes about 8.57 days for the other party to receive this message...... Are you sure to send? ”

Yu Yifeng sighed lightly and nodded again, he didn't know if what he was doing was right or wrong......

According to the assumptions of some scientists, in the dark universe, without the presence of visible light, it is difficult to find an object that does not emit any radiation itself, or only emits a trace of radiation. Therefore, as long as human beings maintain radio silence, alien civilizations may not be able to discover Noah.

But this assumption was quickly overturned, and who knows how long they will stay in the solar system, and who knows if they will explore Mars? As long as a few reconnaissance satellites are launched on Mars, Noah can be discovered, and it is better to put its fate in the hands of its own than to rely on ethereal luck...... This is Yu Yifeng, and this is what most people think!

"Send!" With Yu Yifeng's order, this string of voice messages was sent out by the radio.

The acting was about to be true, and Yu Yifeng immediately ordered Noah to take off from the ground and slowly float above the Martian atmosphere. A large number of "fake" barrels shone slightly, making a posture of imminent attack!

This was followed by anxious waiting, and it took more than eight days for the radio to reach the target......
