The Empress's Swapped Heir

Empress Seraphina (9 tails) and twin Scarlett (8 tails, jealous) both had children with the human prince. Seraphina's heir was pure-blooded; Scarlett's, an ordinary girl. Scarlett swapped her mixed-blood child for Seraphina's. Seraphina saw, remained silent, and swapped them back. For 500 years, Scarlett abused daughter Akari; Seraphina raised 'daughter' Jade. Celestial Ladder trial revealed: Akari was Scarlett's biological daughter, Jade Seraphina's.
