"Yes." Wu Qing replied: "Great disaster." ”

……

17X-S33 star, the third planet.

The earth is barren, and the scorched black land is dotted with big pits one after another.

A winding procession trekked along the edge of the pit.

Sturdy leather armor rolled up into a burden, sharp spears resisted into burdens, the young and old approached the path, the young and old fell behind, and the noble chiefs were lifted high by the strongest warriors and walked in the center of the ranks.

The exception is that in the middle, the most luxurious, and the highest seat, it is no longer the duke, but the prophet.

The four warriors carrying the seat took the lightest and most steady steps, and the team within dozens of steps in front was silent.

The Prophet reclined in his seat, staring at him and not saying a word.

Most of the time, the prophet did not say a word.

But the prophet knows everything.

Set up camp, fend off wild beasts, build bridges, open roads, filter water, and forage for food...... Any difficulty that had previously meant annihilation for this team could be solved with a few words just by going to the Prophet.

But everyone tried not to disturb the prophet.

Because every time the prophet spoke, there was a deep helplessness and sorrow in his eyes.

Everyone said that this world, which was hated by God and destined to be transformed into hell, would be cursed by God every time he let the living escape from calamity, and he would be cursed by God many times, and one curse after another, and what awaits the prophet in the future, everyone dare not imagine.

There is nothing else to offer to the Prophet the best food, the cleanest water, the noblest position, the most secure warrior, and the most sincere respect and affection.

……

17-1C8 star, second planet.

Cave.

Parents cry anxiously for their separated children, children cry out uneasily, wives who have lost all their possessions cling to their husbands, the wounded cry out in pain, and relatives cry in vain while comforting them, making the air of panic even heavier.

Deep in the cave.

Listening to the noise outside, and the occasional loud noise in the distance, from the baron down, the butler, the sheriff, the forester, and the deputy of the captain of the guard, who had injured one leg, all looked solemn.

In the face of a natural disaster that destroys the world, wealth is nothing, force is nothing, and prestige is nothing.

Everything can only rely on the stranger who appeared out of nowhere, but seems to know everything, knows everything, but lets others do everything.

……

F-B112M star, the only planet.

……

9X-CNN37 star, the third planet.

……

Looking at the world after another, Changxing saw two points.

These are all civilizations that have been hit by meteor showers.

In these worlds, "Wu Xiaoqing" has become a leader.

Changxing also had a few doubts.

"How many such civilizations are there? Why do you encounter meteor showers at the same time? Such a continuous meteor shower. ”

Facing the citizens of the Federation whose level of civilization far exceeds that of the earth, Wu Qing does not need to popularize the basic common sense of science: "After seeing so many galaxies and the states of so many planets, I believe you have already guessed about these disasters." ”

"Of course", Changxing nodded, "such a meteor shower on such a large scale and attacking so many galaxies at the same time...... It should be when these planets, these galaxies, and the entire galaxy in which they are located move through the dense zone of space dust and matter. ”

When this guess was spoken, Changxing's squirrel's face was also full of seriousness.

Even for a civilization like the Federation, which is already capable of mass-producing interstellar warships, the movement of galactic celestial bodies encountering a dense zone of space dust and matter is an extremely terrifying scenario.

Looking at what happened to the Dinosaurs in the Cretaceous period of the earth, we know that with the terrifying ultra-high speed of the planet's celestial movements, even if it hits a meteorite with a diameter of only one kilometer, it will mean the destruction of the entire biosphere.

Of course, with the technological level of the Federation's civilization, a single meteorite, or dozens of meteorites, or even hundreds or thousands of meteorites, the Federation may have the ability to push them out of orbit or simply shatter them before they get close to their own galaxy.

However, Changxing's education was enough for him to know that the dense zone of space dust was far from so simple, and the meteorites encountered in the entire river system were far from thousands and hundreds, but in trillions, trillions.

The volume of these dense substances is not as simple as a kilometer in diameter, they are extremely small, even if they are directly smashed into people's faces, they do not feel the slightest, and they are also extremely large - it is not unusual for the entire Federation of 15 planets, and even the stars combined, to be larger than the entire Federation - if the orbit of the celestial body touches such a "dust", even a civilization like the Federation can only wait for death in despair.

In addition to being hit by "dust", which is so large that it is far greater than the mass of the entire galaxy combined, the Milky Way passes through the dense zone of space dust and matter, and there is also the risk of gravitational waves from the tearing of nearby galaxies to change the orbit of galaxies, the risk of super-asteroid explosion caused by huge energy impacts, the risk of black hole effect caused by super weight aggregation, and the risk of indiscriminately annihilating the vacuum zone of space by super civilizations...... And so on and so forth, and these risks are undoubtedly more desperate than the danger of direct impact by super-large "dust", and even the entire civilization has quietly perished without knowing it.

"How long will this meteor shower be?" Changxing asked.

"Judging from the information displayed by the search and rescue boat, the entire river system passes through the dense dust belt completely, and it will take about ......" Wu Qing paused slightly: "...... Two hundred thousand years. “

"Two hundred thousand years," Changxing's eyes widened, even if it was linked to the astronomical scale, 200,000 years was a very long time: "If it has been such a dense impact frequency, this river system does not know how many civilizations will survive in the end." ”

"It won't always be this impact frequency," Wu Qing shook his head, and under Changxing's inquiring gaze, Wu Qing continued, "It's just the beginning...... Even judging from the records of the civilization of the search and rescue team, the dust belt through which this river system passes is extremely dense and dangerous. “

"Extremely dangerous...... Changxing gasped, "So, your mission this time is to save the civilization of this river system?" “

"Of course not." Wu Qing shook his head vigorously: "With our current ability, we can save at most one percent of this river system...... No, one in 10,000. “

As a member of the civilization that is about to enter space, Changxing is not confused by the number of "one in ten thousand", "one in ten thousand, is already very remarkable." There are hundreds of billions of stars in a river system, and one ten-thousandth of it is also tens of millions of stars.

"yes, that's amazing." Wu Qing was also very emotional, but he quickly shook his head again: "But we can't do this." “

"What?"

"We can't save so many civilizations." Without waiting for Changxing to ask, Wu Qingxian directly asked Changxing a question: "In your opinion, what kind of behavior is it for the search and rescue team to save civilization everywhere?" ”

"Great." Changxing replied without hesitation.

"yes, I think it's great, too." Wu Qing nodded, and shook his head again: "But in the eyes of some civilizations, this is a crime. “

Changxing waited quietly, waiting for Wu Qing to continue his narration.

"In our civilization there is an ancient philosophy: the heavens will descend on the people...... Heaven must first make a man miserable in his heart, strain his bones and muscles, make him suffer from hunger, make his skin emaciated, make him suffer from poverty, make him do things upside down, and always be unsatisfactory, and through these things make his heart awake, make his character firm, and increase the talents that he does not possess. - Can you understand this notion? “

"Of course, it's the result of wisdom." Changxing nodded: "Setbacks make people progress...... The more problems you encounter, the more problems you solve, and the stronger your ability to master. “

"Similar to this idea," Wu Qing continued, "In the universe, in the eyes of some civilizations, disasters are like this...... Disasters are a rare opportunity for civilization and a necessary resource for the progress of humanities, science and technology, and morality. “

"Has Civilization Evolved on a Cosmic Scale?" Changxing first pondered, and then asked, "So, what about those civilizations that failed to stand out?" ”

"What is the use of those cookie-cutter civilizations, civilizations that survive by relying on other helps, except for consuming the resources of this universe in vain?"

"So," Changxing frowned, "The civilization that holds this view has the right to speak in the universe?" “

"It's not about having the right to speak." Wu Qing shook his head: "This universe is big enough to accommodate many opinions, so the search and rescue team civilization has a certain space for activity...... This space can be used to save your Federation, to save the Minds, to save the few civilizations we have encountered before, but not this time. “

Changxing keenly understood: "Because the scale of this meteor shower is large enough?" “

"Yes, big enough, grand enough, and dangerous enough." Wu Qing nodded: "The eyes of the universe are all gathered here now...... Keep an eye on how many civilizations will come out on top. “

"At the same time, I will stare at it, will there be some blind civilization to meddle in things?"

"Not really." Wu Xiaoqing smiled: "A civilization that has reached the level of a search and rescue team will easily not clash with each other, but there is indeed some tacit understanding." “

Changxing waited quietly again.

"The tacit understanding is that we can meddle in the 'dead civilization', but we can't do anything to the 'civilization that still has hope of coming to the fore', at least not on a large scale."

"What do you mean by a 'civilization that is already dead', and what does it mean by a 'civilization that still has hope of coming to the fore'? Where is the boundary between the two? “
