Quick Transmigration: The Host Isn't Looking for Love

(One-on-one romance, both leads sexually inexperienced, unconventional plot, a touch of mystery) After dying one day, Ji Ran binds herself to a husky System. From then on, the two embark on a path of quick transmigration, traveling through three thousand small worlds to complete various missions. She utterly crushes scummy male leads and refuses to become the heroine of a tragedy. She turns her tragic fate around and trounces narcissistic male leads. The cannon-fodder female lead makes a comeback and rises to the top. Meanwhile, through each journey across time and space, Ji Ran also seeks to unravel the mysteries of the unknown. What secrets lie hidden behind her? Where will her soul return to, and where will it go? And why does someone keep hanging around her, looking so much like the same person? Falling in love? Not a chance! But later, she eats her words! (Not every world has a male lead. The male lead is the same person throughout, though the heroine only finds out later.)
