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

My sister and I are the princesses of the Feathered Tribe, and we are also the Phoenix Queen candidates appointed by the Phoenix Master. In the last life, we gave birth to children on the same day. I gave birth to fire phoenix eggs, but she laid rotten eggs. My sister was afraid that her cheating would be exposed, so she exchanged her rotten eggs for my fire phoenix eggs on the day of delivery. She was revered as the Phoenix Queen, and for a time she was unparalleled. But because of my cheating, my bones were shaved off due to cramps, and I was thrown into the endless void to die. In a trance, a small dumpling wrapped in flames told me that he was my son. Open your eyes again and go back to the day when the fire phoenix egg broke out of its shell.
