Shi Yue is struck by lightning and sent into an old-fashioned melodramatic romance novel. When she wakes up, she discovers that she's the cannon-fodder junior sister of the male lead's cannon-fodder master. She's the sort of character mentioned only once in the book, a junior sister who dies early because of a cultivation mishap. To prevent her senior brother from meeting his fate of impaling himself on ten thousand swords, she decides to stay by his side and help him cultivate the Heartless Sword.
Later, she discovers that her best friend was struck by lightning along with her, and turned into a sword.
Fine! For her senior brother and her best friend, Shi Xianyu is going to rise to the challenge!
A cultivation-life romance featuring a heroine who acts like a warm, spoiled little troublemaker but is actually indifferent to everything, and a cold-hearted male lead who dotes on her alone.
The original novel's male and female leads are not villainized. The original male lead is upright and old-fashioned, the original heroine is tsundere but kind, and the two of them get together right away.
