Humanity is missing, luckily I have billions of clones.

Chapter 381 The Star is Sick
Leaving traces that neither hinder the normal development of this primitive civilization nor prevent them from having enough power to help themselves in the future requires skill.

As luck would have it, Li Qingsong explored the star system and unexpectedly discovered an asteroid with a rather unusual orbit.

This asteroid reaches a length of 50 kilometers and has a total mass of 20 trillion tons. According to Li Qingsong's calculations, there is a greater than 95% probability that it will collide with that planet in about 500 years.

The impact of an asteroid of such high mass and such large size would unleash energy dozens of times greater than that of the asteroid that wiped out the dinosaurs.

Based on the normal development trajectory, it is highly unlikely that this civilization would have the ability to prevent this asteroid impact in 500 years.

The ultimate demise of this civilization seems inevitable.

However, with Li Qingsong's arrival, things naturally took a different turn.

"This asteroid is a suitable place. I'll leave my mark here..."

Li Qingsong thought to himself, then casually assigned a few spaceships, carrying the corresponding equipment, to land on the asteroid and slightly shift its orbit.

Afterwards, Li Qingsong left a cube with a side length of 1 meter on it.

This cube is made of a strong nuclear material, which can resist the effects of interstellar radiation very well in low-speed environments and can remain undamaged for at least millions of years.

Its side length is exactly one meter, and all the edges are exactly the same length.

Of course, with Li Qingsong's level of technology, he could still detect the error, but for this primitive civilization, even if they developed to the point of landing on this asteroid, they would not be able to detect the error.

Li Qingsong could imagine the shock this primitive civilization would feel when they finally landed on this asteroid and discovered a cube that was impossible to detect any error.

Furthermore, Li Qingsong knew that once they had sufficient capabilities, this civilization would inevitably land on this asteroid.

The reason is simple: since they have developed the technology to the point where they can land on this asteroid, they must have a deep enough understanding of the laws governing celestial motion.

The asteroid's orbit underwent extremely strange changes due to Li Qingsong's interference.

They could calculate that the asteroid's normal orbit had a very high probability of colliding with the large planet where their civilization resided. However, due to some unknown factors, the asteroid's orbit took such an unusual turn, just in time avoiding a collision with their own planet. Therefore, any civilization would want to investigate why.

Once they begin observing the asteroid and try to figure out what happened, they will be able to discover the cube they left behind.

On this cube, Li Qingsong also engraved some of the characters used by this primitive civilization.

"Once you have the ability to travel between stars and leave your home planet to truly enter space, please help us keep an eye out for fleets or civilizations that possess the following characteristics."

Beneath this cube lies a gravitational wave communication device. If you make any discoveries, please inform us of the relevant information through this device. We will then provide you with sufficient compensation, depending on your needs.

Propelling this asteroid to prevent it from colliding with your home planet and causing the destruction of your civilization would be a demonstration of our sincerity.

Respectfully submitted by Lantuk Civilization, Galactic Calendar XXXX.

After finishing his work, Li Qingsong was about to leave. But at that moment, some information detected by the miniature stealth detectors scattered throughout this primitive civilization piqued his interest.

"Oh? So we're at a crucial juncture in the progress of civilization?"

……

Under the dazzling sunlight, Li Qingsong's detector silently floated in the sky, quietly taking in all the movements within a radius of several kilometers without being discovered or noticed by anyone.

Through this detector, Li Qingsong saw a poor village and a dilapidated house.

Several strong, intelligent beings from this primitive civilization, together, violently kicked open the fence of the house, forced their way in, and dragged out a female boy who only had two arms—a sign of inferiority—but whose appearance perfectly matched the primitive civilization's aesthetic.

The young female resisted desperately, crying and shouting in despair, "I won't go with you! Let me go! Help!"

The girl's parents received the news and rushed back from the farmland outside the village, where they ran into the group of burly men.

The father, his face full of anger, charged forward menacingly, raising his arm high halfway there.

Upon reaching him, he slapped the young woman hard across the face.

The young girl stared at her father in shock and fear, only to see him turn to the burly men with a fawning expression: "Master, have mercy! Master, have mercy! You've finally agreed to take my daughter in..."

A burly man snorted arrogantly, ignoring the desperate cries of the young woman, and forcibly dragged her away.

The father continued to bow and scrape, but the mother finally couldn't hold back her emotions any longer and cried out, "My child, it's not that your parents are heartless and don't want you, it's just that only by following the master can you have a way to survive..."

The master initially refused to accept you, but your parents knelt there and begged for three days before he finally agreed to take you in…

……

In a town a dozen miles away, the roads were filled with ragged, dying beggars. Beside them stood a bustling restaurant.

In a private room, the table was laden with delicacies. A portly middle-aged man with three arms discreetly slipped a bag into another man's hand, saying obsequiously, "Sir, the matter of getting those muskets and gunpowder approved is now up to you..."

……

Thousands of miles away, in a luxurious palace complex, four-armed female beings frolicked leisurely, their laughter echoing throughout. A very strong male being, also with four arms and wearing a magnificent crown, sat back in a large seat, watching the frolicking female beings before him and laughing loudly.

A man dressed in official robes entered, his eyes fixed straight ahead, and respectfully reported, "Your Majesty, the weather is now favorable, the land is at peace, even the common people can eat their fill every day, with meat at every meal, and the whole world is praising your virtues..."

"Hahahahaha!"

Upon hearing these words, the strong male creature burst into hearty laughter once again.

……

On the plain, a group of ragged, pale-faced, lowly people with two arms are confronting a group of people dressed in official robes.

"Heaven is not giving us a way out! We've rebelled! We've rebelled!"

A lowly man with both arms, filled with grief and rage, roared: "Kill them! Kill!"

……

Thousands of miles away, amidst towering mountains, a group of strong, savage male beings gathered together.

"The emperors of the Southern Dynasty are incompetent, officials are corrupt, and popular uprisings are rampant. This is our opportunity..."

"Charge into the Southern Dynasty! Seize the throne! Make all the people of the Southern Dynasty slaves and herd their livestock for us!"

"Kill! Kill!"

...Under the miniature stealth detector, everything that happened on this planet entered Li Qingsong's mind, one by one.

"Hey……"

Li Qingsong sighed softly.

Faced with these hardships, Li Qingsong felt deep compassion. But he also knew that he couldn't easily intervene.

Either don't take action, or if you do, be responsible to the end.

Because I will eventually have to leave, I can't stay here for too long.

However, even if one performs a miracle and saves the immediate suffering, the civilization will inevitably face even greater suffering after one leaves.

Because they will almost certainly worship themselves as deities, and may even form elaborate deity-worshipping organizations. And such organizations will inevitably go astray after they leave, further restricting the intellectual and cultural development of this civilization.

This is an objective law governing the development of civilization.

"You still have to fight for a good life yourself; I can't help you with that."

Li Qingsong thought to himself, "However, there is one thing I can do to help you with."

"I'll take care of those barbarians for you."

Although the Southern Dynasty on this planet had developed rudimentary gunpowder gun technology, rampant corruption and poor quality meant it was at a disadvantage against cold weapons.

Once the barbarians invade, there is absolutely no way to stop them.

In Li Qingsong's view, the corruption of civilization and the uprising of the lower classes to overthrow the upper classes are objective laws of the development of civilization, which he cannot easily interfere with.

It is precisely in this constant upheaval that civilization can continue to progress.

However, the invasion of barbarians, which abruptly interrupted the process of civilization's development and even led to its regression, was an unexpected event.

Defeating the barbarians can at most be considered as putting the progress of civilization on the right track, not as forcing growth.

"What methods should we use to deal with those barbarians?"
We need to deal with the barbarians, but the methods can't be too direct to avoid the emergence of god worship... Hmm, let's create a plague.

Li Qingsong quickly collected some biological specimens from the barbarians and, using his biological techniques, developed a targeted virus specifically targeting the barbarian genes in just a few days, which he then casually released.

This virus only targets these barbarians; no other organisms can be infected. Once the majority of the barbarians are killed, the virus will naturally become extinct due to the disappearance of its host, thus preventing its potential for continuous mutation.

In the midst of towering mountains, countless barbarian tribes have gathered together.

Banners fluttered, long swords gleamed, savagery and bloodlust filled the air, and murderous intent soared to the heavens.

But at that moment, a low-ranking soldier suddenly started coughing violently, unable to control himself.

……

Five days later, this army of over 100,000 people disappeared silently into the mountains.

Meanwhile, Li Qingsong had already thrown the dozen or so ships that had entered this star system into the star to destroy all traces. The main fleet, 1.5 light-years away, had set sail again and entered warp space.

Throughout the long journey, Li Qingsong maintained a pattern of sometimes stopping and sometimes setting sail, continuously launching probes into space during these voyages to maintain a speed of 70% of the speed of light and constantly expand his detection area.

Hundreds of years passed in a flash, and Li Qingsong once again sailed more than a thousand light-years away.

Li Qingsong visited star after star, traversed stardust after stardust, and witnessed the birth and death of stars, but he never found any trace of a second civilization.

Up until this moment.

Across several light-years, Li Qingsong once again detected industrial features in a certain star system.

This discovery greatly encouraged Li Qingsong.

"This civilization has a very high level of technology. It has at least reached the stage of strong cores and can conduct interstellar travel."

Hmm... there's a life-bearing planet over there. This must be the home star system of this civilization? They haven't carried out a full-scale civilization migration yet?

However, this star doesn't seem to be in good condition. It's only 50 billion years old, so why is it already showing signs of expansion?

That star, which is clearly less massive than the Sun, has a lifespan of at least 110 billion years. It's only in its prime, yet it's already prematurely aged.

With his gravity-level technology, Li Qingsong quickly figured out the reason.

"I see……"

In Li Qingsong's view, this star has an inherent "defect".

The primordial nebula that formed it contained too many heavy elements, which were deposited into its core as stars formed, much like a tumor in the human body, hindering the normal convection process of matter inside the star.

When a star is young, there is enough hydrogen to prevent this "lump" from affecting the overall structure. However, as the star ages, too much hydrogen is fused into helium, and this lump begins to play a role.

It's like a lump in the body starting to block blood flow.

"A star with a congenital heart disease, how rare, how very rare."

Li Qingsong clicked his tongue in amazement.

The universe is only about 173 billion years old at this stage, and normally the primordial nebula would not have a very high content of heavy elements. However, perhaps due to the ejection of matter from multiple supernova explosions, the primordial nebula that formed this star happens to have such a high content of heavy elements.

"This civilization is both unlucky and lucky."

The unfortunate thing is that the parent star had a congenital heart disease, but the fortunate thing is that it only came to fruition when it developed into a strong core and had the ability to travel between stars on a large scale.

Then the rest is quite simple: assemble a large fleet, carrying all the population and wealth of the civilization, leave this star system, and evolve into a space civilization...

Wait, what is this civilization doing?

Li Qingsong investigated carefully, and the result left him speechless.

On the mother planet where this civilization was born, Li Qingsong saw more than millions of giant thrusters.

Those giant thrusters pointed straight to the sky, constantly spewing out hot, thick tail flames.
