After Turning into a Fly, I Smear Dung on a Scumbag's Face

Kicked out after being used as a substitute wife, I woke up as a fly. And the domineering CEO's beloved first love had turned into a flyswatter. I flew straight to the CEO's face and left a huge welt on his lips. His first love, furious and frantic, smacked him across the face with the flyswatter. I wasn't about to be outdone. I flew to a dung pit, rolled around in it, then rubbed my hands together like a fly and repeatedly scrubbed the CEO's face with all six of my shit-covered legs. The System told me: Make humans angry to earn Rage Points. Earn a hundred million, and you can become human again. I grinned and flew up to the ceiling of the CEO's house. Gu Yanchen, are you ready to welcome the most disgusting ex-wife in the whole city? I thought I was just going to mess with you, until I discovered that your trillion-yuan empire was built on the destiny and fortune of me and your first love. The truth behind the CEO's devoted-lover persona, the Heavenly Dao's karmic punishment system hovering over his head, and what exactly was stolen from the two of us in terms of destiny and fortune? ... I won't just get revenge. I'll uncover every last one of these mysteries. This novel and its characters are entirely fictional. Any resemblance to real people or events is purely coincidental.
