(Quick transmigration, no romance, brainless wish-fulfillment, and a silly, adorable little System)
Setup: a heroine who has a brain but simply doesn't want to use it, and a System obsessed with little wings
Content warning: The heroine is a demon who does whatever she wants. She has no morals and doesn't care about the consequences. If she decides to have a baby the very next second, that's perfectly normal. After all, life is long, so why not have some fun?
System: Demon Lord, Demon Lord, you can't... kill her! If you do, the plot can't continue.
Xian Yan: But she just asked me to beat her to death. I was only doing what she asked.
System: ...Demon Lord, she's got something wrong with her head. Let's not stoop to her level, okay? She's not worth our time!!!
Xian Yan: Oh, is that so?
A sword rose and fell, and the person was cut clean in two... Not a single drop of blood was left on the white floor, a testament to the swordsman's extraordinary skill.
Xian Yan: Do you see? In this world, the only ones I can tolerate are the dead.
System: ... (Stop looking! Stop looking! My Demon Lord kills everything. Let's all go!)
