Deep Palace Knife

In the last life, I was my sister's spear, and I helped her ascend to the throne of phoenix, but I was poisoned by poisonous wine. After she was reborn, she asked me to be her dowry? I prefer to enter the palace as a beautiful girl. A slap in the face can change an imperial edict, and fifty times of "Female Commandments" can change her forever. On the day of the confrontation before the emperor, I told the emperor who gave me death: "My concubine, I would like to be the sharpest knife in your hand." In this life, no one can think of being my master again.
