"Latecomer, if you were born in the Milky Way Orion Spiral Arm after discovering this information, and if you belong to carbon-based life, then be careful, you are under the control of the Extreme Cleaners of the Universe. Don't let the cleaners find out where you are, don't let the cleaners find out where you are......"

The information left by the meteorite civilization contains three parts.

The first part is about civilization, the second part is about the crisis that civilization is encountering, and the third part is about leaving a warning message.

Extreme Purge, another terrifying name appeared in front of everyone's eyes.

"Extreme Cleaners, was the meteorite civilization destroyed by this Cleaner civilization?" When Han Youwei saw this part of the content, her mood was a little heavy.

"The part that tells about the crisis of the meteorite civilization has already been mentioned, and the meteorite civilization was attacked by the cleaners, which led to the destruction of the civilization." Fang Yuan looked at the crisis part first.

"Judging from this information, it seems that we are facing the same crisis as the meteorite civilization, could it be that it is also the cleaner civilization that attacked us?" Han Youwei began to think about the crisis that the earth is facing now.

"It's not certain yet, according to the information we have now, it is the Parasey Soul Advent Civilization that will destroy the Earth." Fang Yuan shook his head slowly.

"Could the advent civilization be the civilization of the Purges?" Eve chimed in.

"It's hard to say, from the point of view of the means of destroying the planet, the means are different, and the meteorite civilization is destroyed by a single particle of light......"

Fang Yuan looked at the deciphered information, and guessed while pondering: "The meteorite civilization took off fifteen spaceships, escaped from the home planet, and saw the destruction of the home planet.

"After they determined that the ship could not escape the pursuit of the Cleaner civilization, it took them twelve days to leave the information in the genes of a tenacious microbe."

Niu Dazhi scratched his scalp and asked, "Which is a grain of light?" ”

"Here, see for yourself. If there is no mistake in deciphering the text, what is written here is a particle of light with mass. Fang Yuan pointed to a line on the deciphered document.

"A light-grained planet?" Niu Dazhi scratched his scalp and didn't understand it.

"I'll have to explain this to Professor Lang." Everyone looked at Lang Tongguang.

Lang Tongguang studied astrophysics, so he naturally knows more about this.

"The particle of light written here should not be a photon, but a mass substance. Theoretically, matter with mass will become infinitely larger as it approaches the speed of light. If you reach the speed of light, not to mention the planets, the stars can be destroyed......"

Lang Tongguang was originally teaching at the university, and he was happy to explain the doubts of these young people: "Of course, the speed of light required to accelerate a mass object in the three-dimensional world is also infinite.

"If an advanced civilization has the technological means to accelerate a particle of mass to the speed of light, it is possible to destroy the planet as long as it is aimed at the right position.

"Also, to add, the speed of light is a constant of the universe, and it belongs to a kind of cosmic law. Don't look at the speed of light in the same way that you think of ordinary speed.

"Judging from the current human cognition, in the three-dimensional universe, the speed of light cannot be surpassed."

Some of the cadets of the military scientific research class understood, and some did not.

"You say, is it possible for the Cleaner Civilization to be a silicon-based civilization like the Star Beast Civilization, I feel that this type of civilization of the Star Beast Civilization is more like an extreme Cleaner who will attack other civilizations when they see it." Eve thought hard and said what was in her heart.

"There is such a possibility. However, judging from the information left by the meteorite civilization, they found the spaceship of the Cleaner civilization, which means that the Cleaner civilization has a spaceship. It's hard to say whether a civilization of this type of Star Beast Civilization will develop a spaceship if it evolves to a high level. ”

Lu Xiuwen didn't agree with Eve's idea very much, but he didn't completely deny it: "However, the star beast civilization we have seen has a civilization level of only 1.1, and it is difficult to say whether there will be a spaceship when it develops to 2.0, or even 3.0." ”

"I still think that the Cleanser Civilization mentioned by the Meteorite Civilization should be the Palese Advent Civilization, and the information I got from Rahu also shows that it is the Palese Civilization that wants to destroy the Earth and the Star Beast World together. This is in line with the civilized practice of the cleaners, but the technological means used are not the same. "Fang Yuan is the one who has seen Rahu the most times, so he knows more about the information of the Palese civilization.

Han Youwei nodded slowly, and then added: "Actually, the meteorite civilization may have been a civilization hundreds of millions of years ago, and for such a long time, maybe the Cleaner civilization has developed to a higher level, or it has changed to another Cleaner civilization.

"With the practices of the Cleanser civilization, it should be easy to have wars with other civilizations. In that case, there is a high possibility that the Cleanser civilization will be destroyed, right? ”

Fang Yuan's jaw head agreed: "It's also reasonable to say this, attacking other civilizations everywhere, the chance of encountering revenge is confirmed.

"Moreover, if the time span is hundreds of millions of years, under the explosion of science and technology, low-level civilizations have every chance to develop into high-level civilizations."

Niu Dazhi has been listening carefully, but he can't fully understand it, but thinking has been going on.

He thought about it very seriously and said: "In this way, if you want to develop into a higher civilization, the most critical strategy is to hide yourself. You've got to be able to steal mines, you know? Just like in the game, you have to steal mines, open sub-bases, develop secretly, develop high-level troops, and then kill back. ”

Several members of the team were a little speechless when they heard Niu Dazhi's analysis.

His statement is indeed too game, but everyone has to admit that his statement is actually right.

In the information left by the meteorite civilization, a warning was also given, so that the civilization that saw this information should not reveal its location.

This coincides with Niu Dazhi's thoughts.

If a civilization wants to develop into a high-level civilization, then when it is weak, it must be hidden and not discovered by the high-level cleanser civilization.

As long as the weakest stage is passed and developed, there is the possibility of confrontation.

It's just that humans no longer have the conditions to carry out this strategy.

Fang Yuan shook his head helplessly and said, "That's right, you're right, we've already been discovered." ”

"That's right. We have all been discovered by advanced civilizations, how can we secretly develop? Eve chimed in.

Niu Dazhi nodded slowly, continued to think seriously, and said after a while: "If that's the case, according to my king-level understanding, now we should drive a spaceship out of the solar system, find a hidden corner, reopen the base, and develop secretly." ”

"You're right, but it's meaningless." Several members of the team commented in unison.
