This story tells the story of a nearly successful experimental subject "Yanyi" who was imprisoned for an unknown number of years in a secret human research experimental base, and another experimental subject who died "Fen Ying" and fought together to escape from the abyss and see the light of day again.
There are not many characters, and the relationships are clear, but the clues are a bit unreasonable, the content of the story is not contemporary, the science and technology are a bit exaggerated, and the overall story has no impact.
Intention: a sudden whim
