Humanity is missing, luckily I have billions of clones.

Chapter 66 Natural Disaster
Li Qingsong was a little surprised to hear this answer.

"What kind of observation methods does your Bluetuk civilization use?"

Momolans said weakly: “Planetary atmosphere spectroscopy technology.

We built a massive array of space telescopes to observe the planets in this system, and we found a third planet that's perfectly in the habitable zone, hot enough to support liquid water.

We determined the elemental composition of the planet's atmosphere and confirmed the presence of life. We also determined whether the atmosphere contained industrial markers and the carbon dioxide concentration curve, confirming that there was no intelligent life on the planet. So, we chose it as a migration target..."

Li Qingsong knew that the so-called industrial markers were a kind of gas that could not be formed naturally and could only be produced through the industrial processes of intelligent life.

Just like the commonly used refrigerator and air-conditioning coolant, Freon is a typical industrial marker.

After this substance is released into the atmosphere, when the planet is located between a distant observer and the sun, this substance in the planet's atmosphere will cause corresponding changes in sunlight.

Distant observers can determine whether the atmosphere of a distant planet contains industrial markers by observing whether there are such changes in sunlight.

If there are industrial markers, it will obviously prove that there is an intelligent civilization on this planet, and that it has developed to a certain level, or at least has entered the industrial age.

But... this alien said there are no industrial signs in the Earth's atmosphere?
How can this be?

Human civilization has developed to the point where we can even build deep space spacecraft in the solar system, yet you say there are no industrial markers in the Earth's atmosphere?

"Still lying."

Li Qingsong sneered and once again controlled the clone to lift the electric shock device over.

Momorans screamed in horror: "I have already answered your question! Why are you still torturing me! Ah——"

While torturing him, they used the Bluetuk people's life support methods to prevent him from dying.

At the same time, Li Qingsong did not stop interrogating the other Bluetuk people.

“Why choose the solar system as the migration target?”

"...We discovered a habitable planet here, but with no industrial markers, indicating the absence of a more intelligent civilization, so we came here.

If there are industrial markers, we wouldn’t dare come here, after all, we have no way of determining the level of technology corresponding to these industrial markers…”

"You lied, and you will be punished!"

“Why choose the solar system as the migration target?”

“…there are no industrial markers…”

"Execution!"

"Execution!"

"Execution!"

When the 366th Bluetuk screamed in pain from the electric shock but still gave the answer "no industrial markers", Li Qingsong felt a little more confused.

Not only was this the case during the interrogation, but he also found a similar description in the mother ship's database.

The captives seemed to really think so.

At this moment, even Li Qingsong couldn't help but feel a little surprised and suspicious.

"Is it true that there are no industrial markers in the Earth's atmosphere? No, it's impossible, it's impossible.

Industrial markers can persist in the atmosphere for a long time, even if all human civilization were to disappear. The Bluetuk main fleet's top speed is only 3% of the speed of light. Taking into account acceleration, deceleration, and inertial travel, it would take at least 900 years to complete.

Their voyage had already been underway for about 500 years. Adding the time for preparation, they had begun observations at least 500 years ago!

At that time, the Earth was already at the end of the feudal era, and early activities such as iron smelting, textiles, dyeing, gunpowder, and agriculture had been carried out on a large scale. There would also be corresponding industrial markers in the atmosphere!
There's no way they can't see it!

There must be industrial landmarks on Earth, and these captives are telling the truth, so there is only one possibility...

These captives have been deceived! For some reason, the leaders of the Bluetuk civilization deceived them!"

Li Qingsong's mind raced as he asked another question.

"I discovered from your database that the environmental exploration mission carried out by your advance fleet is mainly resource exploration.

Your exploration plan shows that you do not seem to intend to survive in the solar system for a long time. Instead, after some predatory and destructive mining, you will set out again to sail away in no more than a few thousand years.

You said before that there are planets in this solar system that are more suitable for your survival, so why do you want to leave here?"

A hint of confusion flashed across Momolan's eyes. "Is this part of our exploration plan? I only know we're going to conduct environmental and resource exploration. I don't know anything else."

After analysis, Li Qingsong believed that what he said was true.

Only people like me who can mobilize a lot of brainpower, analyze the overall situation, and pay enough attention can vaguely perceive the "malice" hidden under the surface detection plan.

It's normal that Momolance doesn't know.

Li Qingsong then asked another question.

"Why do you want to leave your home system and migrate into space?"

"The commander said a 'natural disaster' is coming. If we don't flee quickly, our entire civilization will be destroyed."

"Natural disaster? What natural disaster? According to my observations, the main star of the Gliese 625 galaxy, your home galaxy, is a red dwarf that burns steadily. There's no possibility of drastic changes in the short term.

With your level of technology, you can easily handle planetary catastrophes. What kind of natural disaster would make you abandon your homeland?

Confusion flashed across Momolan's eyes again: "I don't know."

"You do not know?"

"Yes, I don't know. I only know that the scourge is coming and we must escape. That's what the commanders said, so the entire civilization took action. They started preparing hundreds of years ago, and then they set off..."

"You just believe whatever the commander says?"

"of course."

A look of awe crossed Momolans's face. "Following the footsteps of the commanders to the death is the key to the continuation of our civilization. Whether we understand it or not, we should not disobey the commanders' orders."

Li Qingsong smelled a strong scent of conspiracy.

The inexplicable disappearance of human civilization, the blueprint for the migration of all civilizations, without any obvious disasters, and the lower-middle-class people deceived into believing that no intelligent civilization ever existed. A migration plan that was ostensibly a migration, but was actually a pretext for predatory exploitation and then another voyage...

The disappearance of human civilization is definitely related to the Bluetuk civilization!

Even if the Bluetuk civilization was not the mastermind, it was definitely involved in it!
"In about 400 years, your main fleet will arrive..."

Li Qingsong raised his head and looked in the direction of Gliese 625.
