Hi! I need some help??? I can't remember a manwha title dbdnsnsnnd but I remember the summary jwjsjwjajaja (sorry for my bad grammar, English is not my first language TvT)
Summary: it's about a girl who got reincarnated and she invented a gun in the historical era then she helped slaves(?) And she trained the womens (slave) on how to protect themselves and as far as I can remember I think she's a police or a detective in her past life
