In 2095, an advanced alien civilization invaded.
This time:
Genetic engineering would create immortal human bodies!
Cloning technology would bring eternal youth!
Quantum communication, tens of thousands of times faster than 5G, would serve as the brain!
Controlled nuclear fusion would power them as they raced forward!
Antimatter bombs would be their swords of defense!
They would hide in four-dimensional space, and two-dimensional foil would shake the cosmos!
At this moment, humanity declared to the entire universe: Whoever dares attack our planet Earth will be annihilated, no matter how far away they are. The whole world has entered the age of superintelligence!
This novel and its characters are entirely fictional. Any resemblance is purely coincidental. Do not imitate.
Why can't you develop a weapon to defeat aliens even though you have developed a time machine? Generally speaking, the aliens who invade low-tech planets don't have that much force! But I really like novels about climbing the technology tree! Come on!! (???_??)?
