The scientist explained.
—It contains everything we could ever want.
A mere twenty years.
Their consciousness-uploading technology had already become highly advanced.
The initial brain-computer interfaces had long since been abandoned.
As long as all residents soaked in green ionized fluid, their consciousness could enter an electronic simulated world.
There, the residents could experience everything.
They could transform into anything they wanted, even turn the world into a perfect utopia.
They named that place—the Ideal Country.
Gradually.
The residents spent more and more time immersed in the electronic world. Since the ionized fluid could supply them with the energy they needed at any time, they no longer even wished to return to this block-shaped continent they had long since come to know inside out.
Everything outside was entrusted to intelligent robots.
They stopped reproducing.
The number of times they returned to reality gradually fell to zero.
A hundred years later, they had become completely immersed and never woke again.
And during that time.
Their bodies were also evolving rapidly, with every useless organ being evolved away.
Gradually, their limbs, facial features, and even torsos vanished.
All that remained were exposed brains and neural tissue.
That did not prevent them from remaining immersed in the electronic world, while allowing them to absorb nutrients more efficiently and directly.
This continent became as silent as death.
Yet the external robots continued operating flawlessly, following the commands of their programmers and constantly repairing the continent, eventually shaping it into what it was today.
The awakening facilities offered the most direct way to observe their vital states.
The pipelines spread throughout the underground ensured the supply of ionized fluid.
Of all the residents, only 120 million brains in vats remained.
And all of this.
Had happened 1,300 years ago.
After seeing all of it.
