In 1958, the Pirate 1 probe reached Mars.
After landing, the lander module transmitted image data of suspected Martian life forms to Earth, while its satellite confirmed the existence of organisms on the Martian surface.
Shortly thereafter, contact with the lander module was lost.
Subsequently, the probe projects of the two superpowers in the Cold War failed, but this was humanity's first observation of extraterrestrial life.
Unfortunately, due to insufficient observation time, very little information was obtained.
In 1966, a global large-scale project aimed at communicating with alien life, the Alternative 1 Plan, was launched.
In 1967, the geological exploration team of the international permanent lunar base Plato 1, while surveying the interior of the Sacrobosco crater on the lunar surface, accidentally discovered organisms similar to those on Mars, and subsequently lost contact.
Soon after, these organisms attacked various locations on the lunar surface, destroying human bases. This was humanity's first true contact with extraterrestrial life.
These alien life forms were named BETA: Beings of Extra-Terrestrial origin which is Adversary of human race.
Thus, the First Lunar War broke out.
In 1968, the Alternative 2 Plan replaced the Alternative 1 Plan, with the primary goal of finding means to communicate with the BETA through studying their biology and interaction with the environment.
However, although the BETA appeared to be carbon-based life forms, they had no cells, tissues, organs, or systems, which was quite bizarre, making communication impossible.
In the same year, the Northern Superpower began attempting to communicate with the BETA through telepathy.
In 1970, humanity's weapons against the BETA—Tactical Surface Fighters—began to be deployed in the Lunar War.
In 1973, the war turned unfavorable, and the BETA successfully invaded Earth, landing and beginning to construct their first hive, H01.
That same year, in order to eradicate the BETA, humans even deployed nuclear bombs to attack the hive, but found they had almost no effect.
Also that year, because the Alternative 2 Plan showed no progress, the Northern Superpower's telepathy backup plan replaced it as Alternative 3.
This plan would create artificial humans with telepathic abilities to communicate with them, resulting in the sacrifice of most of these artificial humans.
In 1974, she was born into this world that was about to turn into hell.
In 1975, the BETA constructed Hive H02.
In 1976, the BETA constructed Hives H04 and H05.
In 1977, the BETA constructed Hive H06.
In the same year, as the Alternative 3 Plan also had little effect, various countries began to compete for the leadership of Alternative 4.
In 1978, the BETA constructed Hive H07.
In 1979, the G-Element, discovered in 1974, was found to potentially develop into an effective superweapon against the BETA through a series of theories, thus the G-Bomb development plan began.
In 1987, the G-Bomb was successfully developed, a weapon even more terrifying than nuclear bombs, capable of effectively destroying BETA hives.
However, this weapon caused severe ecological damage and could potentially lead to human extinction. Moreover, deploying it to BETA hives required breaking through layers of BETA obstacles, so its use was extremely cautious.
In 1991, she—the genius physicist Yuuko Kouzuki—proposed the "Quantum Causality Theory," which attracted the attention of the Alternative Committee.
In 1995, the United Nations decided to use Yuuko Kouzuki's plan as Alternative 4, thus making her the chief supervisor of this plan.
In the same year, Hive H17 began construction, further compressing humanity's living space.
In 1998, the Far East island nation was also invaded.
In the same year, which is today, Kyoto was officially confirmed to have fallen, with nearly one-third of the country's population dead, and H21 beginning construction.
Simultaneously, the Alternative 5 Plan was again urged to be implemented, as it was confirmed that habitable planets existed in the Bernard star system. Therefore, the purpose of Alternative 5 was interstellar migration.
However, this plan couldn't accommodate too many people, meaning a large number of humans would be abandoned. Therefore, the implementation of Alternative 5 wasn't going smoothly, allowing Alternative 4 to continue its difficult maintenance.
"Dr. Kouzuki, they're urging us again from over there."
A voice intruded into Yuuko Kouzuki's office, bringing the seemingly dazed woman back to her senses as she coldly glanced up.
"I know."
After the person left, Yuuko Kouzuki once again focused her consciousness on the livestream in that special [Dimensional Chat Group].
Currently, this supernatural phenomenon might be a lifeline for saving this world.
Now, the mechanical life forms in the livestream, if their precision components could be obtained and their computing units understood, would greatly benefit Alternative 4, which Yuuko Kouzuki was in charge of.
Of course, understanding the power source technology would also be beneficial.
This is—!
Yuuko Kouzuki suddenly stood up, eyes wide, not because she had discovered something useful from the mechanical spiders' suicide attack on that heavily armored figure.
Correction, she did discover something, but not from the spiders or that humanoid metal canister—the explosion and smoke still covered them, preventing her from seeing anything.
She reacted this way because A2, seemingly concerned about that humanoid canister, moved, causing the camera centered on her to move as well. This revealed a corpse right beside her as she jumped down from the giant machine to the ground.
That wasn't the remains of a mechanical spider; it was clearly the remains of someone from the same group as A2 and the woman piloting the transforming fighter jet. The issue was that this dismembered corpse's internal structure wasn't normal flesh tissue.
"Artificial human?"
No, some organs looked similar but were also artificial synthetic organs, so the blood was obviously synthetic blood.
However, this was different from the artificial human child named Kasumi she had received.
Kasumi was, after all, human, artificially created through genetic engineering.
But the people in the livestream were humanoid robots created by humans, robots with their own thinking.
If she hadn't seen the internal structure, Yuuko Kouzuki wouldn't have doubted their identities up to now, believing they were humans from that world, possibly genetically modified or enhanced humans, or artificial humans like Kasumi.
She didn't expect them to be this kind of artificial human.
This meant that their computational units were beyond imagination, and the technology in their bodies far exceeded Yuuko Kouzuki's understanding, causing her to stare intently.
She wished she could dive into the livestream and bring this corpse back here for immediate analysis and research.
"Oh? There's someone inside? Still alive?"
Yuuko Kouzuki was slightly stunned because the figure of that humanoid canister had now emerged.
It was a tragic sight; the body armor had been blown open and was severely deformed.
But it revealed that there was a person inside, who also looked quite badly injured.
With such injuries, people from her world would certainly not survive, yet the other party could still stand up and was forcibly breaking off the body armor, forcibly removing the armor.
When the entire figure was revealed, it made Yuuko Kouzuki look deeply.
With injuries like these, humans from her side would definitely not survive.
Yet the other party was still alive, and had the strength to break open that heavy armor.
Most importantly, the other party didn't seem like the artificial humans from there, but a human with a genuine flesh body?
