I recommend "Doomsday: Mommy Robbery, Please Lie Down" to you! This was a sci-fi novel about ancient martial arts mecha. It was about a moldy girl who was reborn from the apocalypse. She had a cute baby who killed everyone around her. Along the way, she faced earthquakes, monsters, and the destruction of humanity. Finally, she became the king of doomsday. Besides, this book has already been completed. It fits your needs too well! I hope you like this fairy's recommendation. Muah ~π
