After Rebirth, Will I Be a Prince or a Princess?

[One soul and two bodies]+[Brother and sister? ] Xiao Heng was reborn, but he was completely different from ordinary rebirths - his soul was split into two, and he was born into a twin of a dragon and a phoenix in the palace. The boy was Xiao Linchuan, the sixth prince, and the girl was Xiao Linwan, the seventh prince. I thought that I would be able to live and eat well in this life, but I didn't expect that when they were ten years old, their biological father actually said that he would send them to get married when they were sixteen years old. No, it's easier for men. If you go to get married with your own female body, it will cost you your life! He must escape from the palace before he turns sixteen!
