After transmigrating into the body of the Jade Rat Spirit, I became Nezha's adopted sister.

Thrown into the perilous body of the infamous Golden-Nosed White-Haired Rat Spirit, Bai Yeying finds herself running for her life from the merciless Pagoda-Bearing Heavenly King Li Jing. Just as all hope seems lost, a fierce youth wreathed in flames descends from the heavens—Nezha, the Third Lotus Prince, riding his Wind Fire Wheels with his Universe Ring ablaze. Desperate to survive, the quick-witted mouse spirit immediately latches onto the legendary god of war, spinning quick alibis and shameless pleas that leave the usually volatile deity utterly speechless. From that chaotic first encounter, an unlikely bond is forged. Instead of facing execution, Bai Yeying finds herself whisked away into the heart of legend, miraculously becoming Nezha's adopted sister. Between dodging the wrath of celestial authorities, brazenly stealing divine offerings, and navigating her new life alongside a protective yet perpetually exasperated brother-turned-protector, Bai Yeying discovers that surviving ancient myth is a wild, comedic, and dangerously thrilling ride. But when past enemies close in and the lines between divine duty and familial devotion begin to blur, just how far will the fierce Third Prince go to protect his troublesome new little sister?
