I Was Reborn Until the Day When My Sister Fainted and I Married the Prince of the Heavenly Clan on My Behalf.

My sister and I are Emperor Feng's favorite twins. My younger sister was jealous that I was in love with Cang Qiong, the crown prince of the Celestial Clan, so she got married for me. My mother begged me on her knees to help my sister. In my previous life, I reluctantly agreed for the sake of family honor. The Emperor of Heaven was overjoyed and promised that whoever gave birth to a grandson first would be crowned Crown Princess. My sister and I gave birth to children on the same day, and she exchanged her daughter for my son from the wedding of the prince of the Celestial Clan. The younger sister's mother was named the crown princess based on her son's wealth, and she enjoyed unlimited fame. I was neglected and rejected by the prince. I was drained of my spiritual power and thrown into the cold palace. Her daughter was born a bad person and pushed me into the abyss, saying, "Only if you die can I return to my mother." When I opened my eyes again, I went back to that day.
