If you like the female protagonist's ruthless methods, I recommend you to read the novel "Doomsday Corpses". The female protagonist was reborn after being betrayed and vowed not to choose a lowly life, so her methods were very ruthless. Moreover, this book was a sci-fi space-doomsday crisis novel, which was very suitable for readers who liked doomsday topics. I hope you like this fairy's recommendation. Muah ~π
