After being reborn, I was turned into a slave girl by a princess.

The time-traveling ship slowly descended.

What appeared before the girls was an incredibly magnificent space station.

Chapter 6 Humanity's Defense Line

Pushing open the door to the decompression chamber, Lonnie's eyes were met with a quiet and cold foyer.

Because the air filtration system in this space was long ago damaged, there is almost no air or microorganisms here. Therefore, the oxidation process is relatively weak, and the interior decoration is also relatively well preserved.

……

This foyer was clearly intended for people to practice in the past. Lonnie could identify some exercise equipment, as well as sofas, tables, chairs, and a microwave oven.

On the wall, she also found a medical kit that had already been emptied.

only……

This space station looks huge; it won't be explored in a short time. Just as Lonnie was feeling a bit lost, she heard Elusia's voice in her ear.

"Silly little fox, don't waste your time here. Our goal is just to navigate to the central hub and get to the central passage."

"oh oh……"

Of course, it would be impossible to survive in such a near-vacuum environment using only physical flesh.

So the equipment Lonese is currently using is, of course, the tool used at the Autumn Arts Festival—the suited mannequin!

Its full name is "Girl's Single Combat Jacket". However, compared to the male version in the past, Lonnie is wearing a female version now. Although this style provides less strength, it is more flexible and allows Lonnie to move freely.

With the help of her coat, Lonnie temporarily abandoned her exploration of the front hall and continued along the corridor, soon discovering a heavy metal door.

It appeared to be deliberately locked, and next to the door hung three large characters: "Communication Station".

"Communication station, Elusia, should I enter this place?"

"Yes, but be careful. Be careful not to fall."

"Of course!"

Lonnies turned the handle forcefully, but what she saw next stunned the girl!

Because there were seven or eight corpses lying neatly in the room.

Their flesh had long since decomposed, leaving only white bones. Yet the clothes they wore still represented their former identities.

Soldiers wearing bulletproof vests and scientists wearing white coats.

Beside the soldiers lay several standard-issue rifles. Judging from the empty magazines, they appeared to have been engaged in a fierce battle.

And what about the scientists?

He was clutching a briefcase tightly, seemingly containing very important documents.

……

This scene filled Lornish with a sense of astonishment, but also a touch of sadness... How many years have passed? Centuries, perhaps?

But for so long, no one has been able to collect their bodies.

Have people simply forgotten them?

Or is it that... they simply lack the ability to return to the sky?

The technology of the past has been buried by time, and even those names have been completely covered by the years.

"Elcia, um..."

"Okay, go to the console first and uninstall the navigation hub. Then take the briefcase back to the ship, and I'll analyze it."

"Uh-huh."

Although somewhat nervous, Lonnies successfully completed her mission under Elusia's guidance, bringing back all the necessary resources.

……

……

-------------------

……

……

Back in the familiar cockpit, feeling the familiar light, Lonnie felt a little more at ease.

After receiving the equipment, Elusia approved, saying, "Hmm, not bad. Although some parts are old and damaged, they can still be used after replacement."

"Um, Elusia, the things in the file..."

"Let me see... Oh, it's some research data. It was very useful back then, but it's no longer useful."

"It's useless now?"

"The parts that can be applied have already been updated. The parts that cannot be applied are simply inconvenient to use due to hardware limitations."

"Waaah..."

"However, the navigation center does have some records, which seem to have been left behind by these predecessors before their deaths."

……

……

After saying that, Elusia linked the file to the system, and then a chaotic image appeared on the screen.

Violent explosions rang out outside, and flashes of light flickered on the screen.

"Can you hear me? Can you hear me? This is the T-17 observation post. We are under attack and urgently need support."

A soldier wearing a steel helmet typed anxiously on a keyboard, stating, "Our supplies have run out, but we will not retreat until we receive further instructions!!"

"Dr. Liu was seriously injured, but the data from the observation point remains intact. We will do everything we can to protect him... Please rest assured, even if we sacrifice ourselves, the data will be preserved!"

Even though Elusia stopped playing the video, Lonnies knew what happened next.

Just as rumored, the soldiers did not retreat, and no reinforcements ever arrived.

"Elusia... what are they doing here...?"

"It's very simple: guard the universe and defend against the enemies of the abyss."

"abyss?!"

"Yes, in ancient languages, the abyss refers to the bottomless depths of the earth, right? But in reality, at the end of the last era, the earth was the safest place for people."

"!"

"In order to isolate the influence of some cluttered information, such as observatories for detecting neutrinos (gravitational waves) or dark matter, they are generally built underground."

Many heroic ruins were built underground for protection and to avoid air raids or enemy attention.

"This...this kind of thing..."

Lonnie gasped, only then realizing that both Rainbow Abyss and the Hero's Abode were underground.

Because they are located underground, they have remained largely intact for thousands of years, with little erosion from weathering.

So……

"The abyss... could it refer to the universe?"

"Well, to be precise, it should be other civilizations in the depths of the universe."

"!"

"One of them you've already dealt with directly is the alien civilization represented by the demons. The western demon territories of Kandar, including the current Hofa and Silent Leaf, are all products of this lineage."

"Then, the other one..."

"It's called the Supreme Civilization. You've actually seen it yourself, it's like a civilization on a vast ocean. It's closely associated with the Supreme Civilization... These two civilizations jointly influence our planet, bringing both destruction and rebirth."

"!"

"Silly boy, have you heard of the Dark Forest Theory? In the dark universe, every hunter needs to protect himself and cannot reveal his existence... However, our human civilization cannot be considered a hunter at all."

"What's the meaning……"

"For example, in a previous era, a modern human nation discovered a group of indigenous people on an archipelago. The natives carried iron spears, lived a primitive life of slash-and-burn agriculture, and their bodies were so weak that they could not resist many viruses. So why kill them?"

"!"

Lonnie was startled, realizing that while the Dark Forest Theory made a lot of sense, it only applied to civilizations of equal standing.

Earth, especially for humankind, has far too many weaknesses.

For example, lifespans are too short. With the death of each generation of scientists, knowledge disappears from their minds, and it takes decades for the next generation to learn.

For example, if their physical bodies are too weak, let alone nuclear bombs, even a slightly advanced biotechnology could wipe out an entire race with a special virus.

Yes, humans are intelligent beings.

However, humans, who are born with various disadvantages, are simply no match for cosmic civilizations.

and so……

"Yes, the 'Otherworldly Immortals' represent physical civilization, while the 'Ultimate Ones' represent technological civilization. These two civilizations represent two directions of evolution and are simultaneously influencing Earth, attempting to make it a member of their camp."

Chapter 7 The History of Heroes

Lones learned what had happened from Elusia's account.

So, wasn't the last human era invaded by monsters and many people died?

The culprit behind all this is, of course, the alien civilization.

However, these memories that humans deeply abhor and even grieve over are, in the eyes of the alien civilization... they even consider them a gift to humanity!

Because living organisms can only evolve through elimination.
