I Gave Birth to a Divine Phoenix Egg, but My Sister Replaced It with an Egg

My sister and I are twin girls of the Phoenix clan, and are the most favored concubines of the Phoenix Emperor. In the last life, we gave birth to children on the same day. I gave birth to a divine phoenix egg, but she laid an egg. My sister was afraid that her cheating would be exposed, so she exchanged her eggs for my magical phoenix eggs on the day of delivery. She was named the Phoenix Queen. As the mother of the divine phoenix, she was admired by her tribe and enjoyed infinite glory. But I was spurned, tortured, and burned at the stake by Emperor Feng. When I open my eyes again, I go back to the day I gave birth.
