Lin Wan, a modern-day corporate drone, transmigrates into a cultivation novel as a cannon-fodder supporting female character. Armed with a mysterious guide she obtained by chance, she defies fate and changes her destiny. She carefully plans every move, believing she is resisting fate and using her foreknowledge, only to discover in the middle and later parts of the story, to her shock, that the guide is actually a comeback script she herself sent back through time and space in her previous life, at the cost of all her strength as she lay dying. She is fighting not only the original plot, but also the astonishing, intricately connected scheme she laid herself.
