(The worlds may be split up later, with romance in one version and no romance in another.)
World One, Plane-Side Shop System: She transmigrates into the tragic ex-girlfriend whose research was stolen by her scumbag boyfriend. No problem, she has the Plane-Side Shop System. Qin Buyu develops a new piece of software, and shops from another world move in!
World Two, Game Connects to Ancient Times System: Qin Buyu plays a game and becomes the daughter of a local magnate from the start. In the game, she has a husband who married into her family. He not only dislikes her, but also carries on with his cousin. After forcibly claiming him, Qin Buyu goes on to take many more handsome men by force. But how does she end up becoming a regional overlord?
World Three, Summon Mom System: Qin Buyu arrives in a cultivation world as a substitute junior sister at a cultivation sect. She has another identity, too: she's the daughter in a daughter-raising game from another world. When people make things difficult for her, Qin Buyu summons one mom after another.
World Four, Virtuous Wife System: Qin Buyu arrives in ancient times, where she's expected to be virtuous and proper. Everyone praises her virtue to her face, but behind the scenes, she's a spectacularly sadistic Dom.
Modern-day transmigration as an animal who cultivates immortality; an ancient emperor who can't have children and gives birth to eight treasures at once; the City Skylines game connects to ancient times; a danmei villainess with live-streaming comments; men in ancient times get pregnant and give birth; a guide to becoming a Dragon-Acquiring-Capital protagonist's furnace; starting an education group in an infinite-flow world; Zeus's baby-making adventures in Greek mythology...
The worlds won't necessarily be in order. Some will have couples, and some won't.
I can write whatever you want to read, however wild it is. Feel free to add it to your collection [starry eyes].
