The Underworld's Female Mercenary: Born to Be Wild

She was a 21st-century mercenary who could kill without a trace with a dazzling smile. With one move, she transmigrated into an unfamiliar future. Thanks to her excellent character, she met a cute, scheming genius of a robot. And then everything was turned upside down! In the modern city, she cultivates spiritual power, gambles on mining claims, forges spirit artifacts, grows spirit herbs, raises spirit pets, crushes the underworld, gets involved in military and political affairs, manufactures advanced weapons, and builds a power of her own, climbing step by step to the peak of wealth. Unsatisfied, she even expands to other planets.
