(System + cultivation + transmigrate + transmigrate into a book + villain)
Chu Sanchen has an exceptionally sweet, gentle face, but she never does what she should and throws the Four Continents into utter chaos.
As a Void Illumination cultivator, Sima Shiyuan has always been like a lofty, icy peak in the eyes of the world: elegant, aloof, and untouchable. Yet a woman slaps him twice in a row.
He doesn't know what she looks like or what her name is, and can only spend years searching for her in the vast sea of humanity.
Sima Yu'an, head of the Sima family, has spent years investigating the theft of their mines. At last, he narrows his search down to one person.
He watches the woman slap his grand-uncle. His usually proud grand-uncle only takes her hand and gently blows on it, worried that she hurt herself.
Sima Yu'an's eyes widen in shock. “Grand-uncle, this woman stole the Sima family's mine. You can't just let her get away with it.”
Sima Shiyuan gives him a cold glance, then kneels reverently before the woman. “She's your grand-aunt. How can you call it theft when it's all in the family?”
Chu Sanchen pulls her hand away in disgust. “Who said we're family?”
Sima Shiyuan smiles. “We're both born with wicked bones. We're a match made in heaven, of course we're family.”
(The fun really starts after chapter 38. Most of the earlier chapters lay down clues and groundwork, so readers looking for pure power fantasy can skim them. The one who transmigrates isn't the heroine; she's a native of this world. The System isn't 4588, it refers only to ‘Fengchun.’)
The witch cultivation system was adapted by the author from prehistoric fantasy novels, with a few original touches. Any similarities in ideas are purely coincidental.
