Little Edward couldn't quite say where the girl came from. Perhaps she was the byproduct of a brother's momentary fun.
It was said that after the Little Poison Insect had exhausted a female being, it found a fetus inside the abdomen of that female being.
Perhaps out of the idea of "observing the formation of the neural network," the Little Poison Insect maintained a womb-like environment according to the Demon Sect's secret manual.
It was probably because the New Human had a more resilient life force than the old human— or rather, every cell of the "Benchmark Man" possessed an "injury resistance ability" stronger than that of Homo sapiens. Thus, even under primitive conditions, the fetus still managed to survive.
This was a form of luck... or perhaps it should be said to be "misfortune"?
After the baby was born, her mission was to be the "new toy."
