An Unconventional Heroine

[If a conventional heroine is someone whose mission is to win people's love and do everything she can to win over the male lead, then I must be a very unconventional heroine~] With a System, she transmigrates into the bodies of cannon fodder characters and villains in various little worlds. Instead of winning anyone over, she focuses on managing her own life and living it to the fullest. No romance plot. The heroine is devoted to trying out all kinds of different lifestyles and doesn't date. Plot-focused, with no explicit content. An illogical, wish-fulfillment story with a heroine whose golden finger is so overpowered it breaks through the heavens. The heroine's fans won't budge. The heroine has questionable morals, stops at nothing, and is no traditional good person. She's coolheaded, decisive, and ruthless.
